Are we obligated to help wild creatures?
Kevin Esvelt isn't some madcap transhumanist, but one of the pioneers of CRISPR-based synthetic gene drives:
https://www.media.mit.edu/people/esvelt/overview/
Talk of gene-editing, and even cross-species fertility-regulation, makes a lot of animal activists uncomfortable. But most of the "obvious”, compassionate, non-biological-genetic interventions we can imagine designed to help free-living creatures are either ineffective or would make the problem of wild-animal suffering worse (by triggering population explosions of predators and/or their victims).

Most humans are more sentient than most nonhumans. So one needn't be speciesist (in the arbitrary sense) to agree. My commonsense chronology has always been humans first, then large vertebrates, last of all small obscure invertebrates. But what's disconcerting about CRISPR-based synthetic gene drives is that (in theory) they can invert our intuitive chronology. Small fast-breeders are actually the easiest and cheapest to help. In theory, humans could be the last species in which suffering is eradicated, owing to issues of consent. If some humans always insist on having kids "naturally", involuntary suffering will persist indefinitely. No, I don't think this inverted chronology is likely, but there are too many unknowns to exclude it altogether.

Cruel World or Human Nature? (The Ecologist)
Rationalising human and nonhuman) animal suffering that we can't change is good. Telling ourselves that suffering is not really so terrible – and the cruelties of Nature serve some sort of purpose - helps keep one sane. However, the ethical risk of rationalising human and nonhuman suffering now is that any kind of feel-good story stops humanity from recognising our complicity in its persistence. We are living in the final century where suffering is technically inevitable. The same tools of gene-editing that e.g. WIRED magazine recognises could be used to abolish or trivialise human pain (cf. https://www.wired.com/story/crispr-gene-editing-could-one-day-cut-away-human-pain/) could be extended across the animal kingdom. Unintuitvely, CRISPR-based synthetic gene drives (cf. gene-drives.com) make wild-animal suffering potentially easier to tackle than human suffering. The whole biosphere is programmable - and that includes the optimal levels of physical and mental pain.

Should we conserve violence, suffering and terror or civilise the biosphere with CRISPR?
Darwinian life
("Can a Dolphin Really Commit Rape?)

Suffering and Enlightenment
Agony and a pinprick have something in common: they are both nasty. Nonetheless, it would be fanciful to describe a pinprick as suffering. The actual threshold above which pain becomes suffering is conventional, though not arbitrary. The distinction between pain and suffering has practical advantages too. Getting rid of all experience below "hedonic zero" is a more technically ambitious and a longer-term goal than making pain nothing more than a useful signalling mechanism - as a few human genetic outliers describe their nociceptive systems today.

Wild animal suffering?
I hope you are right to be sceptical, Alexander. Until we can engineer e.g. reversible thalamic bridges or come up with a truly scientific theory of consciousness, the sentience of anyone - human or nonhuman - is speculative. However, both the neocortex and limbic system of some nonhuman animals are bigger than their human counterparts. Genes, neurological structures and behavioural responses to noxious stimuli are strongly conserved across the vertebrate line and beyond. I suspect being eaten alive, for instance, is just as unspeakably awful if you are a juvenile elephant or a human toddler. Alas, we need to reprogram the biosphere, not focus exclusively on a single species.

AGI and Suffering
If machine intelligence doesn't understand pleasure & pain, can it be a moral superpower? Or is sentience the secret sauce that distinguishes full-spectrum superintelligence from digital idiots-savants? IMO, sentient moral agents will civilise Nature:
A Happy Biosphere

[on happy, pain-free CRISPR babies]
“Ending Suffering” Should Be the #1 Transhumanist Priority
Is the problem of suffering genetically soluble this century? For example, could two tiny genetic tweaks get rid of most of the world’s mental and physical pain? (cf. CRISPR gene editing to prevent pain) Compare how Jo Cameron’s unusually high levels of anandamide (from the Sanskrit for “bliss") induces lifelong mild euphoria without impairing critical insight or social responsibility. With CRISPR and preimplantation genetic screening, all babies could be innately happy.

Pitfalls? Tons, yes, where does one start?! But the level of suffering in the living world is now an adjustable parameter. As a society, I think we need a debate about how much pain and misery we want to conserve or create.

* * *

Getting rid of involuntary suffering is only one strand of the transhumanist project. But one needn't be a neo-Buddhist to recognise the importance of phasing out involuntary suffering. Compare the World Health Organization definition of health: https://www.who.int/about/who-we-are/constitution.
Is good health for all as defined by the WHO feasible without biological-genetic interventions? As transhumanists, we all favour radical life-extension. But it's worth recalling that for many millions of people today, life drags on too long. Almost a million people took their own lives each year. Hundreds of millions of people suffer from the horrors of depression. We need an integrated approach to ensure that all sentient beings can flourish.

KaramQa, religious believers and scientific rationalists alike can support getting rid of involuntary suffering. The difference is that scientific rationalists have the tools for the job. For instance, consider the proposal for a large well-controlled trial of CRISPR babies with benign versions of the FAAH gene and FAAH-OUT gene (cf. "She Thought It Was Normal"). Creating “transhuman” children who wouldn't suffer like neurotypical humans would be highly controversial. I can think of lots of risks to be weighed. But the proposal is not ill-defined or religiously-inspired.

Unquantifiable suffering? Recall how behavioural psychologists "operationalise" levels of pain and pleasure by testing how hard human and nonhuman animals will work to obtain or avoid rewarding or noxious stimuli. The results of behavioural tests tend to coincide with the reports of verbally competent adult human subjects. The genetic, pharmacological, neurobiological and behavioural evidence all converges.

Intuitively, yes, discontent is the engine of progress. But compare the rapid advance of AI without the nasty "raw feels" of distress. Most relevantly for us, what's critical for intellectual and societal progress is information-sensitivity to “good” and “bad” stimuli, not our absolute point on the hedonic scale. As it happens, the people with the highest hedonic set-points also tend to be the most motivated. Conversely, pain-ridden depressives are prone to get "stuck in a rut". (cf. gradients.com)

Yes, it's good to research in depth everything that could go wrong - whether phasing out the biology of suffering, ending aging, or creating full-spectrum superintelligence. But forewarned is forearmed. Consider again the chronically happy and pain-free Jo Cameron with her unique(?) double mutation of the FAAH and FAAH-OUT genes. Jo is a socially responsible vegan, retired schoolteacher, and pillar of the local community - not (as far as I know) a crazed serial killer.

As well exhaustively researching everything that could go wrong, I think as transhumanists we should also explore what could go right. Pain thresholds, default anxiety levels, hedonic range and hedonic set-points are now adjustable parameters in human and nonhuman animals alike. As a society, we need a debate about how much suffering we want to preserve in the living world. We are living in the final century of life on Earth where involuntary suffering is inevitable.

Tim, yes, raising IQ scores is feasible. I doubt the enhancement of the controversial Chinese CRISPR twins was done "inadvertently":
https://www.technologyreview.com/s/612997/the-crispr-twins-had-their-brains-altered/
But given our crude conception of intelligence, boosting children’s IQ would almost certainly boost their AQ too:
IQ tests
A more "autistic" cognitive style may (or may not) be desirable for society as a whole; but this cognitive shift almost certainly won't be preplanned, just a by-product.

I guess I'm more comfortable pushing a eugenics program geared to promoting individual subjective well-being - though intelligence-amplification is probably inevitable in the long run too.

“Turn your wounds into wisdom.”
(Oprah Winfrey)
Does suffering make one wise?
Alas, the only thing suffering has taught me is that pain ought not to exist...
The next step in human evolution?

The Family That Feels Almost No Pain
Syndromes where "sufferers" feel almost no pain but information-signalling is conserved hint at the possibility of creating a "low-pain" world - and without assuming crazily advanced technology.

Imagine if a predisposition to chronic low mood and high anxiety were recognised as a serious but treatable hereditary genetic disorder - with all prospective parents given the opportunity to have healthy offspring as part of basic healthcare:

One can guess some of the pitfalls. Today (in the UK) around 1 in 7 children each year end up in causality. Accidents happen. Parents don't get blamed for having kids who do reckless things. But what will be the media response when the first high-pain threshold, high hedonic set-point CRISPR kid falls victim to something similar? "Evil Scientists Murdered My Baby Says Grieving Mother", etc. If the child had been more neurotic, would the accident have been averted? With the help of genome-editing and smart prostheses, I think civilisation will eventually switch to a more civilised signaling system. But the complications are huge and far-reaching.

[on the Measurement Problem of Quantum Mechanics]
Are the measurement problem of QM and the binding problem of neuroscience two sides of the same coin?
A solution to the measurement problem of QM?
("How serious is the measurement problem concerning the validity of the various interpretations in quantum mechanics?")

[on non-materialist physicalism]
“Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental. It cannot be accounted for in terms of anything else.”
(Erwin Schrödinger)
A German edition of my “Schrödinger’s neurons” conjecture:
Schrödinger’s neurons?
Not to be confused with
Schrödinger’s cat

Manu, a couple of points:
1. Consciousness realism.
What would it mean to say your headache is an "illusion"? Headaches and illusions alike are kinds of consciousness. Only a small minority of researchers are anti-realists about consciousness. But among consciousness realists, there is a big divide between:
a) a minority of philosophically-inclined folk who believe all one ever knows directly are the contents of one’s own conscious mind the phenomenal world-simulation it runs
and
b) direct realists, who believe they directly access via perception the mind-independent physical world. Most perceptual direct realists tend to identify consciousness with the serial stream of logico-linguistic thought and reflective self-awareness (seemingly) located just behind their forehead. By contrast, if inferential realism is true, consciousness embraces your entire world-simulation - of which your body-image is just a small part.

I am confident that consciousness realism is true. Likewise inferential realism about the mind-independent world and a world-simulation account of perception. The ethical relevance of this view is just to reaffirm that animals from worms to pigs to babies are subjects of experience and worthy of moral consideration. Hence the abolitionist project genetically to reprogram the biosphere.

2. The Hard Problem of consciousness (and the binding problem, the palette problem, the problem of (non-redundant) causal-functional efficacy, etc).

All solutions are intuitively crazy. I explore non-materialst physicalism - more specially, the quantum-theoretic version of the intrinsic nature argument. Unlike consciousness realism and a world-simulation story of perception, I don't pretend to know if non-materialist physicalism is true. It's empirically adequate and potentially experimentally falsifiable. I won’t claim more. It's also so counter-intuitive I struggle to take it seriously at times.

Non-materialist physicalism transposes the entire mathematical apparatus of modern physics to an idealist ontology. Strictly, consciousness is around 13.8 billion years old. Quantum field theory describes fields of sentience rather than insentience. Our minds and the world-simulations we run disclose the intrinsic nature of the physical.

One might guess that - in common with animism, property-dualist panpsychism and traditional idealism - non-materialist physicalism very generously populates reality with mind. But no. Rocks, plants, digital computers and so forth aren’t unified subjects of experience. So what makes awake animal mind-brains special? Non-psychotic phenomenal binding. I could now go off on my quantum mind spiel. If non-materialist physicalism and classical field theory were true, then we'd be micro-experiential zombies, mere aggregates of mind-dust, just like plants, rocks and digital computers. But the superposition principle of QM allows classically-impossible phenomenal binding in the brain. Zurek’s “Quantum Darwinism” (i.e. the decoherence program in mainstream quantum mechanics) applied to the CNS offers a potential selection-mechanism to explain why some quantum-coherent superpositions of neuronal feature-processors are more dynamically stable than others.

Ethical implications? Well, on this story, silicon robots, digital computers of all kinds, future “whole-brain emulations" (etc) aren’t going to wake up. Centuries from now, maybe non-biological quantum computers will be unified subjects of experience. But we've no grounds for thinking they’ll be endowed with a pleasure-pain axis. Tomorrow’s cyborgs raise complications but no more.

However, what if the story above is fundamentally wrong? After all, the majority of AI researchers believe that digital computers will sooner or later "wake up". Most AI researchers and computer science professionals are consciousness realists but also implicitly epiphenomenalists. And consciousness anti-realists? If you are an anti-realist, then maybe you worry that silicon robots or video-game characters will somehow undergo the "illusion" of agony. IMO, the distinction between appearance and reality collapses with the “raw feels” of subjective experience. If you believe you're undergoing terrible pain, then you're undergoing terrible pain. Maybe you also think that it's God punishing you for your sins (or whatever), but losing faith in God doesn’t get rid of the pain. I normally treat Brian as a consciousness realist because if the consciousness anti-realism he avows were literally true, then I can't see how his work would have any value. It's only the fact that consciousness realism is true that makes questions like e.g. "Can video game characters suffer?" of intellectual interest and ethical importance.

Now back to "Modern Combat Versus"...

Magnus, a quantum superposition ("cat state") is an individual physical state. We know (or rather believe) that superpositions must be real because of e.g. the classically-impossible interference signature in a double-slit experiment.
Assume:
1) quantum mechanics is complete (i.e. no hidden variables or "dynamical collapse" story)
(2) the intrinsic nature argument (i.e. our phenomenal minds disclose the essence of the physical)
When you experience, say, a unified cat, that unity doesn't consist in an aggregate of classical neurons firing (edge-detectors, motion-detectors, colour-mediating neurons and so forth). If that were so, then you'd just be a microexperiential zombie. Instead, the unity consists in individual superpositions of distributed neuronal feature-processors.

A critic may respond that neuronal superpositions don't exist: But if so, quantum mechanics is incomplete / false.
Another critic will respond that neuronal superpositions are irrelevant to consciousness. The dynamical timescale is wrong - femtoseconds not milliseconds.
But if the intrinsic nature argument is true, then this objection doesn't work. Consciousness is the essence of the physical. So any individual physical state is consciousness.

To stress, I don't know whether the intrinsic nature argument for non-materialist physicalism is true. I'm agnostic. I just explore its implications. Some of these counterintuitive implications can be experimentally (dis)confirmed via interferometry. The results can thereby verify or falsify the conjecture. Most likely the true explanation transcends our conceptual scheme.

[on veganism]
The anti-speciesist revolution will be messy...
Holy wedlock
("Vegan bride slammed for banning meat-eating relatives from big day")
A cruelty-free lifestyle can be criticised with varying levels of sophistication.
NatWest worker told customer 'vegans should be punched'

Will tasty meat substitutes (“Beyond Meat” etc) be enough to get the death factories shut and outlawed? Or will cultured meat and animal products be the only way to end the animal holocaust and “veganise” the world?

("An Amazon engineer made an AI-powered cat flap to stop his cat from bringing home dead animals")

Falloutfan2002, the stem cells for growing cultured meat can in principle be extracted via biopsy by veterinarians in the course of a legitimate medical procedure to help the nonhuman animal in question. In theory, one can argue there are still ethical issues of consent - the same could be said of stem cells extracted from humans - but any further debate now gets rather theological. I suspect the real objection of some vegans and animal activists to cultured meat isn't really about the source of stem cells, but rather a sense that cultured meat is a distraction. Factory-farms and slaughterhouses should be shut and outlawed now, not at some nebulous time in the future when cheap gourmet cultured products finally reach the supermarkets. And of course I agree – in principle. Talking about developing such technical fixes in the midst of an animal holocaust feels morally frivolous. Yet we've got to be hard-headed. Sociologically, politically, what is the quickest and most effective way to end industrialised animal abuse worldwide? Vegans shouldn't over-estimate our powers of persuasion. The only credible way I know to get factory-farms and slaughterhouses shut in our lifetime (rather than over centuries) is to ensure zero personal inconvenience to morally apathetic consumers - with the bonus of being able to signal one's superior virtue by choosing in vitro products over otherwise identical traditional meat.
This may sound cynical – sorry – but I’m just trying to be dispassionate. What will work?

“Universal compassion is the only guarantee of morality.”
(Schopenhauer)
Or cultured meat?
Will vegetarians ever comprise more than half of the world’s population?

The closure of factory-farms and slaughterhouses will probably involve paying reparations to the owners and perpetrators. But it’s a price worth paying.
When slaveowners got reparations

Paying to harm sentient beings isn't EA. Instead, EAs should support getting slaughterhouses shut and outlawed. Without slaughterhouses, the whole apparatus of industrialised animal abuse will collapse. We've no hope of creating a world based on systematically helping sentient beings if we are systematically harming them instead - or paying others to do so:
47% of Americans agree with ban on slaughterhouses

Understandable - but IMO misguided. Cultured meat is the best hope of getting all factory-farms and slaughterhouses shut and outlawed in our lifetime...

Reality and Perception

[on Brock Bastian's critique of The Hedonistic Imperative]
"The Other Side of Happiness Embracing a More Fearless Approach to Living" (2018)
by Brock Bastian.

"There are four reasons why I think we should be sceptical of Pearce's project":
1) Hedonic adaptation theory
The quick and lazy refutation is intracranial self-stimulation of the mesolimbic dopamine system ("wireheading"). Wireheading doesn't show physiological tolerance. It's as exhilarating after ten hours as ten minutes.
However, HI doesn't urge ending hedonic adaptation, but rather, ratcheting up hedonic range and hedonic set-points:
Gradients.com & What is the root cause of all suffering?.

2) The relativity of pain and pleasure
("How would we ever know what pleasure is if we experienced nothing else?")
Some people, tragically, endure chronic pain and depression.
Would we seriously claim that pain-ridden depressives can't really understand pain and depression because they can't contrast ghastly states of mind with experiences above hedonic zero?

3) Pain and pleasure are two sides of the same coin
("Narrowed emotional bandwidth")
Yes, we could create a narrow-contrast, equable +95 to +100 civilisation.
But we could also create a high-contrast, mercurial +70 to +100 civilisation.
Tomorrow's hedonic floor can be higher than today's hedonic ceiling. Hedonic contrast can be softened or amplified as desired. Our emotional palette can be diversified as well.

4) The paradox of hedonism
("According to Pearce we should aim to seek pleasure")
In the sense we should upgrade our reward circuitry, i.e. hedonic recalibration and enrichment, yes.
But all of the things we care about (unrelated to pleasure conceived as such) can in future be pursued with greater vigour, motivation and drive for success if we biologically-genetically upgrade. Hedonic recalibration can conserve your values and preferences - and conserve critical insight and social responsibility.
Hedonic recalibration doesn't entail buying into someone else's vision of utopia.

According to Brock Bastian (and Jordan Petersen et al.), pain and suffering give life more meaning.
But empirically, prolonged suffering and low mood tend to drain life of meaning.
Other things being equal, more happiness promotes more meaning too.

Jason, agreed, the track record of utopias isn’t good. But phasing out the biology of involuntary suffering isn’t the vision of a perfect world. Even a CRISPR-driven biohappiness revolution isn’t the recipe for utopia. Raising your hedonic range doesn’t call for heroic sacrifices. Nor does ratcheting up your hedonic set-point harm others, or entail abandoning your existing values, or call for ruinous expense. I think there should be exhaustive research exploring all the conceivable ways anything and everything could go wrong in world without experience below hedonic zero. But talk of “sacrificial skulls” is IMO alarmist. No sentient being need be harmed. For what its worth, I urge (as a negative utilitarian) high-tech Jainism...

A couple of reservations.
First, compare how The Global Happiness Report ranks Indonesia at 92 in the world with, say,
https://www.economist.com/international/2012/02/25/chilled-out
In other words, all sorts of anomalies arise when we blend our judgements of who "ought" to be (un)happy with who self-reportedly is (un)happy.
The danger of making such sceptical comments is they encourage tolerance of social injustice and inequality. But most people still think that improving society is the panacea for a happy world, whereas it's only half the story. Biological-genetic interventions will be essential too. There are an awful lot of unhappy Finns (cf. https://yle.fi/uutiset/osasto/news/more_than_400000_people_in_finland_take_anti-depressants/10639847).

Second, if the Global Happiness Report recorded the (un)happiness of only white people, it would leap off the page. Recording the (un)happiness of humans seems natural and unremarkable. The plight of non-human animals is invisible.
I fear a true Global Happiness Report might read quite differently.
That said, roll on unlimited material abundance for all...

Great video. Thanks for making it. Could I just clarify one point? You quote me as saying “the future belongs to life lovers”. This wasn't intended as an endorsement. Rather, it was a comment about the nature of selection pressure. The problem is that "hard" and "soft" anti-natalists alike tend to remove ourselves from the gene pool. If I thought selection pressure in favour of natalism could be overcome, then I'd be a "hard" anti-natalist too.

Benevolent Artificial Antinatalism
A Reply to Thomas Metzinger
As Neuralink scenarios move from hype to reality, I think greater-than-human intelligence is going to be "us" rather than some alien being that emerges from smart software in digital computers (the original I.J. Good Intelligence Explosion scenario) whether by accident or design. My views on AI and ethics are fairly idiosyncratic (cf. Quantum Ethics). So let's assume instead Thomas Metzinger's artificial super-ethicist scenario. An AGI (sentient or nonsentient?) has been created to advise humanity on ethical issues. What is the most sociologically credible outcome? Whether we realise it or not, some human value-systems (Buddhism, negative utilitarianism, classical utilitarianism etc) are inconsistent with long-term human survival. It doesn’t take AGI to work this out. But human survival is axiomatic in other value-systems, especially religious value-systems. The only effect of choosing to stay childfree is to intensify selection pressure against (any predisposition to) antinatalism.

Also, how smart do we suppose this AGI super-ethicist advisor is going to be? Many ethical dilemmas are insoluble by any level of intelligence - for the same reason that the conflicting preferences of 100 different football supporters for their respective team to win the cup are irreconcilable. Yet if this hypothetical AGI is seriously intelligent, then presumably it can advise prospective parents on how to have kids with a higher hedonic range, higher hedonic set-points, lower pain thresholds, and even gradients of lifelong superhuman bliss - perhaps the ultimate fate of life in the cosmos. Such advice is more likely to be heeded than advice to stay childfree.

Trying to model the nature of selection pressure in the wake of the coming reproductive revolution involves too many unknowns to be done with any confidence. But IMO we can be fairly confident of one prediction: the future belongs to life-lovers with a strong status quo bias in favour of their own survival and reproduction – in some guise. Anti-natalists, negative utilitarians and all subscribers to suffering-focused ethics need to accept that (for evolutionary reasons) this status quo bias is ineradicable - even if some of us might privately wish the whole pain-ridden horror-show would just stop.

Nature is a cruel machine for creating suffering. Once Darwinian malware starts to proliferate, it can’t be stopped.

Life in the Year 3000

Today’s psychonauts know that the weird states of consciousness induced by major psychedelics are impossible to express to the drug-naïve within the resources of our conceptual scheme. But what about everyday life in a civilisation with a hedonic range of, say +70 to a plus +100 compared to our -10 to 0 to +10? Have we any sense what life might be like? Wittgenstein remarked how “The world of the happy is quite different from that of the unhappy”, but what about the world of the superhappy? If faced with a conservative audience, it's wise to stress how most traditional values and preferences can be conserved by extreme hedonic recalibration. In principle, this promise could be kept. In practice, I suspect most of today’s bric-a-brac will seem irrelevant to posthuman minds:
The Tyranny of the Intentional Object

[on "mixed" states]
Physical Pain as Pleasure
What is the future of "mixed" states? Pure pleasure (or pure ill-being) can be mild, moderate or superhumanly intense. But a lot of human states of mind are a mixture of the pleasant and pleasant - with either the positive or negative aspect dominating. For keen BDSM aficionados, the positive dominates. More widely, however, I think a lot of people fear that a superhappy world - even a world underpinned by preference-conserving gradients of bliss - would deprive their lives of something valuable. For instance, consider our nearest and dearest. Alas, friends, family and lovers aren't always a source of unalloyed delight. Yet most people would reject the option of replacing their loved ones with pure pleasure - unless of course they actually tried the euphoriant in question, but that’s a different story. Clearly, any story of the long-term future of mixed states is speculative. In a civilisation with a hedonic range of +70 to a +100, there could be pure seventies, eighties and nineties with complicated mixed states too (Anything hedonically sub-zero from the Darwinian era would be literally inconceivable). But maybe the future lies in hedonic purity. Sticking to this century, my main reservation about even broadly positive mixed states is that they simply aren't rewarding enough. Take meditation. People who meditate typically report positive effects. Yet even its advocates acknowledge "difficult" experiences (cf. Meditation: problems)

On a more practical note, I wonder what will happen when we finally discover the molecular signature of pure bliss. Despite the cardinal role of the mu opioid receptor in current research (cf. The mu opioid receptor) I think the heart of the mystery lies inside the neuron – with the huge complication that any adequate theory of mind needs an account of phenomenal binding.

I wonder how (and when) the big breakthrough will come? IMO, the existence of life based entirely on gradients of bliss will eventually be a background assumption of everyday living - nothing “deep” or philosophical, let alone controversial.

[on physics]
How empirically adequate is modern science?
The State of Physics
Orrab, first, I suspect many (most?) physicists would agree with your minimalist approach. Quantum mechanics works: what more can we want? Wordy philosophical tracts can be written on whether the purpose of science is to understand the universe or "just” to devise empirically adequate theories. However, in my view, the problem of quantum mechanics is that it's not even empirically adequate. The unitary Schrödinger dynamics suggests that superpositions, including macro-superpositions, should be ubiquitous. Instead, we experience - or at least appear to experience - only definite outcomes. Why? See too e.g. Paul Mainwood's answer to "Does decoherence solve the measurement problem in quantum theory?" I suspect you'll find my answer (and especially the links) too "philosophical" and speculative for your taste. But all physics is steeped in philosophical assumptions. Ignoring them doesn’t transcend philosophy, but instead risks giving treacherous philosophical assumptions a free pass. IMO!

[on the meaning of life]
The Meaning Machine
Post-Darwinian life will probably be orders of magnitude richer in subjective meaning, significance and purpose than our own. Such superhuman meaning will be a side-effect of upgrading our reward circuitry, not the consequence of discovering some deep metaphysical truth about the universe. There is an irony to pleas from well-known pundits like Jordan Peterson who call for prioritising "meaning" over happiness. Getting rid of the biology of suffering in favour of gradients of bliss will create a Meaning Explosion.

I guess critics will be exasperated at this response. What counts is true meaning (mine!) over false meaning (yours). Yet the beauty of hedonic recalibration is that - with complications and subtleties for sure - recalibration enriches everyone's default quality of life without taking sides.

This is what’s disconcerting about eternalism: even if a “Big Rip” scenario is true, it’s still the case spacetime (tenselessly) exists. Like modelling the Big Bang, we’re describing merely its boundaries.
Meaning? I fear you will find this answer frustrating:
Meaning or the end of suffering?
But in essence, a sense of meaninglessness and futility is a function of low mood. Lift your mood and everything will seem charged with significance and purpose again. Sometimes one wants meaning in a transcendent sense; it’s not clear what this sense could be. However, biotech can take care of empirical meaning.

Contra Searle

Thanks Dzarren. I should have said a bit more. First, some scene-setting. Some very smart people do and don't regard the phenomenal binding problem as a fundamental challenge to physicalism. The seeming (partial) structural mismatch between our minds and the microstructure of the CNS pushes David Chalmers to dualism. Why aren't we (at most) just 86 billion odd pixels of classical, membrane-bound “mind-dust”, or at least just a bunch of distributed neuronal feature-processors? Even if consciousness is fundamental to the world, what explains the classically impossible unity of our minds and the world-simulations we run?

I explore an out-of-the-box solution, namely that our minds consist of neuronal superpositions ("cat states”) of distributed feature-processors. The reason the conjecture is unorthodox is not because of any new theory of physics, but because the theoretical lifetime of neuronal superpositions in the CNS is femtoseconds - or less! This kind of timescale is, intuitively, hopelessly wrong for the two kinds of holism to be related. Anyhow, the binding problem as standardly posed simply assumes (rather than derives from QFT) the existence of classical (i.e. decohered) neurons of the kind we can seemingly inspect under a light microscope.
What would we discover if we could inspect an awake brain on a timescale of femtoseconds?

[on a zero ontology]
"Real knowledge is to know the extent of one's ignorance.”
(Confucius)
Why is there something rather than nothing?

Russell, many thanks. On your first point, I essentially agree: inconceivability differs from incoherence. If we can rigorously set out what the absence of any properties at all would amount to, then the simple fact we can't imagine such global absence doesn't exclude its possibility. As you say, rather than reifying nothingness, we should instead strip away objects, events, and properties, everything - including information, which plays such a cardinal role in modern physics. Now to what stunned me. Information, theorists tell us, can neither be created nor destroyed. After trying and failing to conceive of what no properties at all would entail, and ruminating on Ed Tryon’s zero-energy vacuum-fluctuation universe conjecture, I stumbled across (from classical information theory) the idea that zero information = all possible descriptions. This struck me as a really freaky coincidence - at least if one takes Everettian QM seriously, as I do - although there are important differences between classical and quantum information (see above). “Nothing = everything” sounds like some pseudo-profound Zen koan. It’s embarrassing to write. But there may be a sense in which physics hints it’s true.

Anyhow, a couple of more points.
First, of course we don't know if Everettian QM is true. Theoretical physicists working on quantum gravity and the black hole information paradox, and experimentalists probing for any collapse-like deviation from the unitary Schrödinger dynamics, aren't tackling the "philosophical” mystery of why anything exists. But if unitarity is violated, then an informationless zero ontology will be falsified too. So perhaps it’s not just philosophical musing.

Second, even if (in some sense our minds can’t grasp) the information content of reality does turn out to be zero, then one will still want to protest that an informationless zero ontology is not...well, nothing. But when the search for an explanation is too difficult, sometimes all one can hope for is finding an explanation-space instead. If an informationless zero ontology is the wrong explanation-space, then I've no idea where we should even start looking for answers.

Thanks for sharing Michael! May I start with your comment that "Information is ubiquitous but ...not conserved" - since if you're right (and you may turn out to be) then any kind of informationless zero ontology will be falsified. Most physicists believe that the world has a lot of information (capped perhaps by the Bekenstein bound) but information can neither be created nor destroyed - raising the question of where it came from in the first instance. An informationless zero ontology says it didn’t!

I see the Akademe Foundation that you hotlink is a Zen monastic order. The conjecture that the information content of reality is zero itself sounds distinctly Zen-like. But what (if I might ask) are your grounds for believing information isn’t conserved? A “dynamical collapse” theory to resolve the measurement problem in QM would entail the creation of information, as would some solutions to the black-hole information-loss paradox and some candidates for a theory of quantum gravity. Yet (and this is what I find so tantalising) there are countless ways we can naively imagine an information-rich reality – from all the world’s major religions to classical physics to Copenhagen-style quantum mechanics. Yet unitary-only quantum cosmology seems to be hinting – I won’t put it more strongly – that an informationless zero ontology might be true. I find this a pretty freaky coincidence. Maybe it’s a false clue to the fundamental mystery; but if a zero ontology is totally misconceived, then I’m stumped…

Is the superposition principle universal?

[on nootropics / smart drugs]
Newsweek on nootropics:
Nootropics: Do ‘Smart Drugs’ Really Work?
Newsweek:
1) When did you start using nootropics?
2) What stack do you currently take? How has that changed over time?
3) How has your life changed since taking nootropics?
4) Do you think general interest in nootropics is growing? If so, why?
5) My personal response (from a privileged viewpoint of neurotypicality/good health): I find that suffering—in moderation—plays an important role in my human experience. Despite suffering registering as a negative sensation, it is as enriching to me as positive emotions. Is it possible that managing suffering should centre not around abolition, but through balance, ie. not suffering excessively? I can’t help but imagine a suffering-free existence as somehow flat; two-dimensional.
6) Do you think it’s possible that our obsession with maximum happiness and productivity is a byproduct of protestant capitalist value system? Don’t our feelings of tiredness and craving for unproductivity give us a form of ‘downtime’? In a lot of online forums, I notice that people often seem to be into nootropics in order to fuel an already stretched life.
7) Do you see a move towards a future where it’s considered usual to take nootropics? How do you think this future will come about?
8) What is the next big development in technology in the field?
9) What do you think stands in the way of this future?
10) Finally, how would you suggest people get into nootropics if they were curious? Is there anything they should be careful around?

First, some background. I have a melancholic temperament. My main personal interest has been in finding sustainable mood-brighteners that don't impair intellectual function - and ideally, sharpen it. This is a challenge. Some forms of low mood are associated with a poverty of thought; other kinds with "hypercholinergic frenzy", i.e. an overactive cholinergic system. Anticholinergics can improve mood and impair cognitive function. Conversely, cholinergic drugs can subdue mood and enhance thinking – one pitfall to bear in mind when exploring nootropics. Of course, many people who take nootropics aren't melancholic. Most users of nootropics report taking them purely for their cognitive effects. Maybe so; but some drugs touted as nootropics (e.g. methylphenidate / Ritalin) are really psychostimulants. Other things being equal, if you feel happier, you feel sharper. Often you are shaper - although compare depressive realism. Mood and cognition are intimately linked. Crudely speaking, psychostimulants enhance signal-to-noise ratio, but calling psychostimulants "nootropics" / "smart drugs" / "cognitive enhancers" (or whatever) can be misleading: typically, they enhance merely one kind of cognitive style.

1. I first used selegiline in 1995. I wrote "The Hedonistic Imperative" six weeks later, in late 1995. I've taken selegiline (at a selective MAO-b selective dosage of 2 x 5mg daily) ever since.

2. Since 2000, I've also taken amineptine (c. 200 mg daily). I almost didn't try amineptine because most tricyclics have a "dumb drug" anticholinergic action. Amineptine (and tianeptine, another very interesting agent) are anomalous: they modestly improve cognitive performance on some measures. But it’s hard to separate out any truly nootropic action from the effects of a drug on mood and arousal.
Otherwise, I’m afraid my stack is quite "boring" compared to serious psychonauts:
What is DP's current supplement regimen?

3. I function better in a harsh Darwinian world.

4. The growth of the scientific counterculture, free web-based access to information (both medical/scientific and social / anecdotal) and a global online drug market with easy methods of payment (bitcoin etc) have all increased interest in nootropics.

5. Not all experience is straightforwardly either good or bad. Emotionally "mixed" states, for example bitter-sweet nostalgia, can be perceived as valuable, on balance. But in my view, unpleasant human experiences such as depression, anxiety disorders, despair, agony, jealousy and even "normal" malaise are cruel and ultimately pointless. Even if we judge that many nasty emotions can be functionally useful, I think the key question to ask is whether they are functionally indispensable, or whether we can replace them by more civilised alternatives - for example, information-sensitive gradients of well-being. Critically, I think we should be free to choose lifelong gradients of intelligent bliss. In 1998, I co-founded the World Transhumanist Association (now rebranded as Humanity Plus) with philosopher Nick Bostrom. The Transhumanist Declaration sets out our commitment to the well-being of all sentience. When transhumanists talk of overcoming suffering, aging and our human intellectual limitations, we would do well always to stress the word "voluntary"- even when the voluntary nature of what we’re talking about strikes us as self-evident. No one is going to force you to be happier or longer-lived or smarter. Most suffering in the world today is involuntary. Mastery of our genetic source code promises a world where we’ll be free to choose whether to suffer or not. Later this century and beyond, the level of suffering in the biosphere will be an adjustable parameter.

Intuitively, yes, a world without suffering would be emotionally flatter. One thinks of "psychic anaesthetisers" like SSRIs. And what about tormented geniuses who create great works of art and literature? But designer drugs and (soon) gene therapy can potentially enrich our palette of emotions and ratchet up both our hedonic range and hedonic set-points. In other words, we can potentially enhance mood, cognition and human diversity.

6. The pleasure-pain axis is a universal feature of animal life. But human cultures vary hugely in how much value they place on personal fulfilment versus welfare of the tribe or society as a whole. I could give you a long spiel on evils of capitalism. Yet free-market capitalism didn’t invent the hedonic treadmill. Discontent is genetically adaptive. Nature didn’t design most of us to be constitutionally happy.

7. Common, yes. Usual? I don’t know. Compared to the designer-drug cocktails of tomorrow, taking today’s agents may seem little better than glue-sniffing. A vast unregulated drug experiment is currently unfolding across the world with the growth of online pharmacies selling all kinds of pills and supplements – and also a massive expansion of the so-called Dark Web. I don’t know how the experiment will play out.

8. In the 2011 movie “Limitless”, a struggling writer discovers a nootropic (“NZT-48”), which turns him into an intellectual superman. It’s a fun story, but I’m sceptical that any such drug could exist. Incremental progress involving not just nootropics but also smart neuroprostheses and soon biohacking the genome are more likely than development a single miracle drug. For instance, many people are getting their genome sequenced, now prices have crashed. Pharmacogenomics offers the prospect of personalised medicine and cocktails of smart drugs tailored to the individual rather than today hit-and-miss approach. For now, suck-it-and-see is still the norm.

9. Status quo bias. Taking a “dumb drug” like ethyl alcohol is socially acceptable, at least in Western culture, whereas use of smart drug is still relatively atypical. I think the appeal-to-nature argument still resonates with a lot of people. Hence the number of products that claim to be “naturally inspired”.

10. Before even considering taking nootropics (or any other kind of psychoactive drug), I’d urge anyone first to optimise their diet, aerobic exercise and sleep discipline. Getting all three right is more likely to deliver long-term cognitive enhancement than taking pills - though some people strike lucky and find a drug or cocktail that really suits them. Then perhaps consider nutraceuticals (“smart foods”) and omega-3 essential fatty acid supplementation. Also, ask yourself what aspect of your normal state of mind you would most like to change. Lots of people say they’d like a better memory. But the capacity selectively to forget stuff, and discard trivia, can be at least as vital for intellectual performance as having a good memory. More generally, I think schools should offer students optimal nutrition i.e. smart snacks and smart drinks, rather than smart drugs. It’s crazy that the USA consumes around 90% of the world’s Ritalin. Breastfeeding should be universally encouraged. (As it happens, the most intelligent person I know was breast-fed almost to the age of five – though this sort of anecdote shouldn’t be confused with a well-controlled study!)

Pitfalls? Where does one start? Many of the scientific studies often cited are small, unreplicated, poorly controlled, and don’t disclose source of funding. Publication bias is endemic. Acute action and long-term effects of nootropics aren't always carefully distinguished: the brain has an incredibly complex web of negative feedback mechanisms. Online merchants are obviously trying to make a profit, so they aren’t impartial sources of information. Any form of psychoactive drug use has implications not just for the user, but also for friends, family and partner(s). Robinson Crusoe should be free to take any drug he wants, but the rest of us are social primates. Modafinil, for example, is a generally benign nootropic with low abuse potential. But like most psychostimulants, modafinil may subtly impair empathy. And sleep deprivation tends to harm cognitive health. For what it’s worth, I prefer strong black coffee. In my view, we need a much richer conception of intelligence. Yes, we need tools to enhance (what might crudely be called) the “autistic” component of general intelligence measured by mind-blind “IQ” tests and SAT scores. But we also need tools to enhance social cognition - and enrich the capacity for co-operative problem-solving that helped drive the evolution of distinctively human intelligence.
In short, I think we need full-spectrum superintelligence!

Life on Earth
Benjamin, yes, sorry, it's a grim diagnosis, although not many pessimists anticipate a future of superhuman bliss. I confess I haven't read all 1,928 pages of Parfit's "On What Matters" - just the reviews. If (dis)value can be naturalised, then perhaps the negative utilitarian faces a bigger challenge than the classical utilitarian, who may argue that the pain-pleasure axis discloses the world’s inbuilt metric of (dis)value. Our successors may regard NU as a depressive psychosis. If so, I hope they are right.

Opportunities for an astronomical reduction of suffering
Thanks Manu. Despite leaning to the Rare Earth hypothesis, I used to speculate about cosmic rescue missions after we'd eradicated suffering here at home.

Hedonism for Kids

[Adam Ford asks]
How do the fundamental utilitarian ideas that suffering is bad and pleasure is good become axioms?

1) the scientific world-picture. Physics tells us that no here-and-nows are special or ontologically privileged.
2) one's own experience. The badness of, say, agony is self-intimating: it can't be defined in terms of anything else. If you want to understand why agony is inherently bad, try placing your hand on a hot stove. It's not an "open question" whether one's unbearable agony is disvaluable. Subjectively (dis)valuable states are an objective property of reality.

Of course, natural selection hasn’t made most of us utilitarians - quite the contrary. Each of us is prey to the egocentric delusion:
Are you the centre of the universe?
Nice and nasty hedonic tone gets "painted" onto all kinds of otherwise neutral stimuli/experiences that promote or detract from the inclusive fitness of one's genes. So bitter disputes arise. But for reasons we don't understand, the pain-pleasure axis discloses the worlds' intrinsic metric of (dis)value.

It's by no means clear that utilitarianism – whether classical or negative – is consistent with human survival.
The Utilitronium Shockwave

[on the binding problem and QM]
Does consciousness have quantum properties?
Most people who've considered the phenomenal binding problem assume that binding must be classical, even though we don't understand how it's possible. So if a pack of neurons can be a unified subject of experience, then why not a termite colony too: perhaps we should be looking for a functionalist, information-theoretic explanation? However, as you'll have gathered, I think phenomenal binding is classically inexplicable. If instead our experience of phenomenally-bound perceptual objects within our world-simulations consists of coherent superpositions of distributed neuronal feature-processors, could other systems like a termite colony support unified subjects of experience too? Probably not, IMO. Recall I'm assuming no new physics, just the unitary Schrödinger dynamics. Whereas the effective theoretical lifetime of neuronal superpositions in the CNS is less than femtoseconds, then the effective lifetime of superpositions of cephalic ganglia in a termite colony must be...I don’t know, zeptoseconds or less. Environmentally-induced decoherence must be insanely powerful and uncontrollable. Of course, most scientists would say the same about decoherence in the human CNS…

Quantum Darwinism in the CNS
I did a quick Google search on "Quantum Darwinism in the CNS". Alas, the only other reference I could find was in The Paracast - "The Gold Standard of Paranormal Radio". However, Quantum Darwinism and the decoherence program are now mainstream physics. Zurek is widely respected. What's not mainstream is the idea this inconceivably powerful selection mechanism has any relevance to our minds and the world-simulations we run. As standardly posed, the phenomenal binding/combination problem just assumes decohered neurons and classical physics.

Are particles conscious? & If consciousness is fundamental, what predictions does it make?
Thanks Rares! I'm not a Fichte (or Kant!) scholar so I hope Miguel will forgive me if I comment just on the section of your remarks discussing non-materialst physicalism. The actual term is due to the late Grover Maxwell. I sometimes say "physicalist idealism" instead. But some readers then assume that one must be some sort of anti-realist, or believe in a consciousness-induced wavefunction collapse, so “non-materialist physicalism” is probably wise. Only disbelievers in the collapse of the wavefunction are also wavefunction monists: most wavefunction monists are "materialst" physicalists who (unlike non-materialist physicalists) face the Hard Problem of consciousness and its offshoots, which are difficult to reconcile with their professed monism.
I think the real challenge may be to find experimentalists who specialise in molecular matter-wave interferometry who reckon the conjecture is even worth falsifying. Most researchers will just think “That’s flaky!” and move on - a fair if frustrating response to a seriously weird proposal. See too:
Wavefunction monism

Robert, yes, naively, conjecturing that consciousness is fundamental is the recipe for (over-)populating the world with mind. But classical aggregates aren't minds even when - as with programmable digital computers or trained up connectionist networks - they behave in ways that strike us as mindlike and even (super-)intelligent.

The quantum version of the intrinsic nature argument doesn't rest on any additional assumptions (beyond the formal completeness of quantum physics). Rather, it treats what critics see as the reductio ad absurdum of quantum mind as a falsifiable prediction. And perhaps critics are right: it's a conjecture, not an affirmation of faith.

The cost of consciousness
I don't know if panpsychism (or non-materialist physicalism) is true. But the conjecture that the only part of the world with which one is directly acquainted, i.e. one's own conscious mind, is different in kind from the rest of the universe is quite bold. Why should fields inside and outside our heads differ in their intrinsic nature? Maybe they are just differently organised. If the mathematical apparatus of QFT describes fields of sentience rather than insentience, then there is no Hard Problem of consciousness - or problem of non-redundant causal efficacy.

If we want to understand the functional role of consciousness in the animal kingdom - and why rocks, plants and digital computers aren't unified subjects of experience - I think we should focus on phenomenal binding. Without binding, we'd be microexperiential zombies (Phil Goff's term). Even partial breakdowns of phenomenal binding carry a huge fitness cost. The snag here is that no one knows how such an insanely adaptive feature of our minds - and the phenomenal world-simulations we run - is physically possible if we assume neurons are decohered classical objects:
Is consciousness adaptive

Why Some Scientists Believe the Universe Is Conscious
Property-dualist panpsychism is worth distinguishing from non-materialist physicalism, i.e. the conjecture that our minds disclose the intrinsic nature of the physical. I don't blame anyone who thinks non-materialist physicalism (or traditional panpsychism) is too absurd to merit scientific discussion. But such a critic shouldn't claim the assumption that the mysterious “fire” in the equations is non-experiential is a scientific discovery. It's a (plausible) philosophical opinion.

Assume instead that the intrinsic nature argument for non-materialist physicalism is correct. What follows? The conjecture that the universe is consciousness, i.e. fields of sentience rather than insentience, differs from the claim that the universe is conscious. Attempting to derive the latter from the former might seem an obvious fallacy of composition. However, a big complication here is that many (most?) cosmologists assume wavefunction monism. Stephen Hawking, notoriously, once described Everett as "trivially true". So if (1) non-materialist physicalism and (2) wavefunction monism are true, then why isn’t reality one big psychotic mega-mind?

I don’t know. But I would guess the answer lies in decoherence. Or alternatively, non-materialist physicalism is false:
Consciouness: emergent or fundamental?

[on preference utilitarianism versus hedonistic utilitarianism]
What are your philosophical positions in a paragraph?
Many thanks Bryer. You are very kind.
Others things being equal, yes, the satisfaction of preferences is good. Allow me to make the case for the ultimate primacy of the pain-pleasure axis.
You prefer peppery food, just as (to use a racier example) some people have a taste for masochism. But that's because peppery food (and BDSM in some folk) triggers the release of intensely rewarding endogenous opioids. Keep the endogenous opioid-release while stripping away the pain and the experience would be even more enjoyable!
I'm curious about your wisdom-teeth extraction. Can you pinpoint why you wanted to the pain to go away - if it weren’t unpleasantly distracting?
Grief is complicated. I'd love to see an end to death and aging. Yet until advanced medicine can solve the problem of mortality, I say (if asked) that I'd like my death or misfortune to diminish the well-being of family and friends, but not for them to suffer on my account - and this principle should be universalised if possible.
Can a distinction be drawn between enjoyment and pleasure, as you suggest - with some aspect of enjoyment being bound up with the status quo? Perhaps consider Felipe De Brigard's Inverse Experience Machine argument:
Does Nozick's experience machine prove anything?
Does the experience machine (pleasure machine) argument adequately refute hedonism?
Also, satisfaction of vast numbers of preferences is literally impossible - either because they depend on a false metaphysics (e.g. I want to do the Will of Allah) or because the preferences conflict with the preferences of others (ranging from the conflicting preferences of predators and prey to the preferences of rival football fans for their team to win the cup).
Anyhow, much more could be said on preference utilitarianism: I know I've just skimmed the surface of the issues. But you'll see where I'm coming from, so to speak.
Thanks again!

Hmmm. I wonder whether our experience differs or our interpretation - not that the two can be cleanly distinguished. According to my perspective, pure pains may stretch from, say, - 1 to -10 in intensity, with -1 being a pinprick and -10 agony. One wouldn't describe a pinprick as “suffering", and indeed the precise point on the scale where mere pain becomes suffering is conventional though not arbitrary. Yet a pinprick is still a self-intimating micro-nastiness. If asked, I'd rather not have a pinprick - quite aside from anything else it signified.

The situation is more complicated with "mixed" states - especially when over time an otherwise painful stimulus becomes ever more tightly associated with rewarding endogenous opioid release. A masochist might deny he wants to experience the rewarding opioid-release on its own: otherwise painful or humiliating stimuli have become inseparably associated with enjoyable experience in his mind.

So to use your example, I would predict that vanilla ice cream with pecans and chocolate syrup do not induce the same quality of endogenous opioid release as spicy food - and neuroscanning of your brain would confirm this. Or co-administer an opioid antagonist like naltrexone to see how robustly your preference for spicy food was retained.

To stress, other things being equal, I'm all in favour of preference-maximisation - mine and everyone else's. But I haven't a clue how to reconcile everyone’s conflicting preferences worldwide, whereas I do know (in principle!) how to make everyone happy - and moreover how to do so without overriding their existing values and preferences, except insofar as their existing values and preferences are inconsistent with hedonic recalibration. Nix, yes, "pleasure" for any experience above hedonic zero, "pain" for any experience below it. This crude dichotomy is too useful to give up, though it's simplistic, e.g. what about mixed states? I'm not an orthodox "hedonistic" utilitarian. In my view, our overriding ethical obligation is to minimise suffering, i.e. negative utilitarianism. However, after intelligent moral agents have phased out experience below hedonic zero, let's create a civilisation based on gradients of intelligent bliss. By contrast, hedonistic utilitarianism has a counterintuitive implications that its originators may not have foreseen: What is the secret of eternal happiness?

[on antidepressants and creativity]
Manu, any drug with anticholinergic properties (e.g. most of the old tricyclic antidepressants, and paroxetine of the SSRIs) is likely to be a "dumb drug” – potentially causing word-finding difficulties, memory lapses and impaired concentration. Very high doses of anticholinergics can lead to delirium and sometimes euphoria. But the problem with all SSRIs can be a flattening of emotion. A lot of creative writing stems from "storm and stress", so to speak. Instead of being marketed as antidepressants, SSRIs could just as well have been marketed as antianxiety drugs with an emotional buffering action. The reputation of MAOI antidepressants has never really recovered from when the "cheese effect" (i.e. tyramine-induced hypertensive crises) wasn’t understood. But MAOIs aren't likely to sap your creative muse. Selegiline may even be a cognitive enhancer. Selegiline loses its MAO-b selective effect at dosages over 5 x 10mg daily but a low-strength EMSAM patch doesn't need dietary restrictions. Amineptine is another example of an antidepressant that doesn't adversely affect creativity. Alas, amineptine only really suits melancholic depressives and is hard to obtain.

[on politics]
Accusing one's political opponents of being senile (etc) has a long history. But Donald Trump is showing clinical signs of dementia. Obviously, Trump still has a huge cognitive reserves of cunning. But the signs are going to get worse. By contrast, Adolf Hitler in the 1930s was at the height of his intellectual powers. Yes, I'm sure Trump would love to be President/dictator for life – he’d keep power if he could. Yet he simply doesn't have the intellectual capacity to engineer a coup - even if the political conditions were right, and I’m sceptical. Perhaps the biggest danger isn’t a Trump dictatorship, but rather America blundering into war. Fortunately, Trump seems keener on winning the Nobel Peace Prize like his predecessor than foreign adventures. But the worry must be that instead of peacefully being voted out of office – or stepping down at the end of a second-term - he'd take the rest of the world down with him. I know many transhumanists working in the field of global catastrophic and existential risk believe the greatest threat to human civilisation is unfriendly AI. But sadly, I don't reckon our chances of avoiding catastrophic nuclear war this century are better than even.
Does Trump have dementia?

Women can be just as evil as men. But the evil takes different forms. Whether in chimpanzees or humans, history doesn’t record a single instance of women banding together for the purpose of wars of territorial aggression. All-female governance would be a crude but technically effective way to mitigate global catastrophic risk. The idea of electing an all-female political class is presumably fanciful. But catastrophic nuclear war is quite likely this century. Politics as a women-only profession would probably prevent it. Whether such a price of prevention is too high is open to debate. By analogy, imagine if study revealed that the overwhelming majority of airline accidents involved pilots of one gender. Yes, transitioning the aviation industry to a future of all-male / all-female pilots would be unfair to the majority of potential pilots of the risky gender - most of whom could be trained to fly without incident. But the “sexist” and discriminatory transition would be appropriate on safety grounds. So what about national politics in an era of WMD - where the stakes are orders of magnitude higher?

Or will sensationalist claims that "many developed countries are getting dumber" turn out to be an artifact of junk science?

[on computer (in)sentience]
"Keeping meat in the loop will inevitably slow things down."
If one conceives of humans as functionally no different from digital computers, then perhaps your perspective follows Tim. But as you know, some of us argue that classical digital computers will always be zombies, incapable of supporting conscious minds and their phenomenally-bound world-simulations. Rather than our being residual "fairly harmless organic scum on the top of the machine civilization" (that's such a good quote, I may borrow it!) humans and our AI-enhanced and genetically rewritten descendants may turn out to be the key to the plot. Richard, strong (but contested) arguments can be offered that digital zombies won't "wake up" and become sentient. AGI prophets respond that sentience is computationally redundant. Deep Blue doesn't need to be sentient, or even understand it’s playing chess, to beat any human at an adversarial game like chess. This lesson can be generalised to all - or almost all - cognitive domains. The only thing consciousness is functionally good for is for having interminable debates about consciousness!

For what it’s worth, I’m sceptical of the possibility of AGI. Full-spectrum superintelligence will be our AI-augmented genetically-written descendants, not digital zombies. Most AI researchers would reject such biological chauvinism…

Erlend, if a classical digital computer is ever convinced that it is experiencing the colour red, then my account of consciousness, phenomenal binding and the intrinsic nature of the physical is mistaken! Note I'm not denying that we may fruitfully take the intentional stance and claim, anthropomorphically, that e.g. Deep Blue is convinced it can mate me in three.

Does the denial that a classical digital computer can experience redness or the phenomenology of belief depend on an

If non-materialist physicalism is false, then yes. But the intrinsic nature argument for non-materialist physicalism / constitutive panpsychism seems to be gaining ground in academia. Former critics like Phil Goff have swung round. You may or may not find the quantum-theoretic version of the intrinsic nature argument that I explore to be a credible option. Yet critically, it's experimentally falsifiable via interferometry:

[on p-zombies]
Would p-zombies discuss consciousness?
Yes, let's agree that p-zombies are physically impossible. The interesting question is to understand why. Given the basic laws of physics and chemistry, together with the assumption that the "fire" in the equations in non-experiential, your insentient molecular duplicate would type exactly the same keys for your comment above as you do. Strictly, it wouldn't intend to make the same point because it has no subjective intentions. But I might anthropomorphically describe it as making the same point as you. Apparently, every supposed adaptive advantage conferred by consciousness would be conferred by the same physical behaviour under another description that didn’t invoke subjective experience. Instead, I explore non-materialist physicalism and a non-classical account of binding. (cf. How should we categorize the binding problem in the context of easy and hard problem of consciousness?) I don't know whether the conjecture is true. But if so, then p-zombies and micro-experiential zombies are impossible because they are unphysical.

Chris, My best guess is that whole-brain emulation is impossible (cf. Is the brain a quantum computer?) with literally limitless resources, the behaviour of the mind-brain could presumably be modelled via a gigantic lookup table. But IMO the system in question would still be a micro-experiential zombie. That said, my ideas are idiosyncratic:
Quantum Mind

* * *

The Hard Problem of consciousness arises only if we make a (very) plausible metaphysical assumption. The "fire" in the equations, the essence of the physical, is non-experiential. Non-materialist physicalism drops this plausible assumption. However, what drives philosophers like David Chalmers to reject monistic physicalism in favour of dualism isn't (just) the intuitive absurdity of quantum field theory describing fields of sentience. Rather, Chalmers highlights the (apparent) partial "structural mismatch” between our phenomenally-bound minds and the microstructure of the CNS. Why aren’t we, at most, “micro-experiential zombies”? If physicalism is true, then there must be a perfect structural match. The “Schrödinger’s neurons” conjecture I explore claims there is a perfect structural match – and the non-classical inference signature will (dis)confirm it.

However, you say "You can’t a priori predict the taste of an orange with mathematics". Alas, I agree with you. That's because we lack any kind of cosmic Rosetta stone, so to speak, to "read off” the values of experience from the solutions to the equations. In other words, our ignorance doesn’t stem from some "element of reality" that’s missing from the formalism of physics.

I'm modestly optimistic about science dissolving the Hard Problem. I’m pessimistic about understanding consciousness any deep sense.

Do you think the scientific investigation of consciousness should be postponed until after we have phased out the biology of suffering?

We've two challenges, one technical, and the other socio-political.
The technical challenge is to spell out how a happy biosphere is feasible. Even otherwise sympathetic people assume that the idea of the lion and wolf lying down with the lamb is ecologically illiterate. No blueprint or policy document drawn up now is ever going to be adopted. Such work is still a useful corrective to the kneejerk response, “There is no alternative!"

The sociopolitical challenge is more daunting. For instance, most people aren't ready to accept that new humans should be endowed with "low-pain", high hedonic set-point genes - let alone spreading benign code throughout the biosphere via synthetic gene drives.

Peter, quite a few of the people whom society labels "psychopaths" may be self-haters. But intelligent, self-avowed psychopaths I've interacted with don't give much sign of self-loathing. I guess psychopathy is dimensional rather than categorical too. Each of us finds himself or herself the centre of the universe - with other people playing walk-on parts and possessing merely hypothetical feelings. So perhaps it's not surprising that some "psychopathic" folk take appearances at face value. I recall interacting with an intelligent psychopath who asked me to convince him he should be moral. Open individualism - ideally extended to nonhumans - may be helpful here, though I incline to less helpful "empty" individualism. If open individualism is true, then the distinction between decision-theoretic rationality and morality collapses - which admittedly sounds too good to be true.

[on artificial intelligence]
Will AI destroy humanity?
My (minority) view is that the vast majority of problems that intelligent biological minds can tackle are too difficult for programmable digital computers to solve. Thus if I want to create and investigate a multitude of different state-spaces of consciousness, then I know in principle what needs to be done. By contrast, a classical digital computer has no conception of consciousness, let alone the capacity to create and explore its varieties. In a sense, perhaps a digital computer could be programmed to embark on such a research program - but only by creating the genetic source code for the manufacture of phenomenally-unified biological minds (such as us) that are capable of classically-impossible phenomenal binding.

To stress, my views on consciousness and binding are unorthodox - though not unmotivated.

Thanks Dan, Just to clarify, yes, my working assumption is that classical digital computers / connectionist systems / silicon robots don't need moral consideration because they will always be zombies, or technically micro-experiential zombies. But this stance isn’t the same as crude biological chauvinism. Next century and beyond, maybe non-biological quantum computers will be unified subjects of experience - though I'm sceptical artificial quantum computers will have a pleasure-pain axis:
Could quantum computing cause sentience?

Of course, it's always good to bear in mind the possibility one could be radically mistaken - especially when ethical issues of sentience are at stake. I know some very smart people (e.g. Max Tegmark, Nick Bostrom) who don't recognise the binding problem as a fundamental mystery at all. By contrast, its (apparent) insolubility by monistic physicalism – even non-materialist physicalism - drives David Chalmers to dualism.

Using CRISPR to cut away pain

Robert, ethically, let's agree: it's vastly more important to get rid of the really nasty stuff than to eradicate literally all experience below hedonic zero - let alone create a civilisation of based entirely on superhuman bliss. We may ask why Nature didn't genetically create a civilised signalling system. Intuitively, as you say, it's because pain and suffering are more motivating than mere gradients of subjective well-being. Yet many humans (and nonhuman animals) will undergo quite extraordinary extremes of suffering in order to obtain a fitness-enhancing reward - or obtain a euphoriant drug that "hijacks" their reward circuitry. So the answer is complicated. One clue is that low mood is associated with behavioural suppression: typically, it’s less "risky" to be a depressive realist than a hyperthymic optimist. But these are processing biases that in future can - in principle - be intelligently compensated for.

Obviously, everyone’s genetic dial-settings for hedonic range and hedonic set-points can’t yet be precisely tweaked, let alone routinely designed to order. But a civilisation of (super-)Jo Camerons and (super-)Anders Sandbergs is clearly technically feasible. If you never feel (non-trivial) pain, and if you have "a ridiculously high hedonic set-point" (Anders), then by default you enjoy an extremely high subjective quality of life. As case studies like Jo or Anders show, critical insight and social responsibility needn't be impaired either. So I wonder what is the right balance for us to strike? If we lived in a world where most people agreed we should be working towards a hyperthymic, effectively pain-free civilisation, then I'd be urging exhaustive research into all the obvious and non-obvious ways things could go wrong with genome-editing. But right now, focusing on the multitude of subtle ways things could go wrong feels faintly absurd. Most parents of the 130 million babies born each year still aren't considering anything beyond the traditional genetic crapshoot and all the horrors it brings.

Regrettably, the organisation that defines health as “a state of complete physical, mental and social well-being” (World Health Organisation constitution) has just proposed a halt to the only way such health can be achieved:
WHO says no more gene-edited babies
It’s going to be a long struggle.

Octavio, the WHO is (1) widely internationally respected and (2) committed to the same goals as members of this group, i.e. good health for all. WHO members may not have thought through what delivering good health for all entails, i.e. healthy genomes. But it's easier to persuade people to embrace what their own principles entail than to persuade them to adopt a different set of principles altogether. So IMO we should persevere.

Tim, just as Marx once claimed he wasn't a Marxist, maybe Darwin reborn would claim he wasn't a Darwinist. I don't know! But the raw material for natural selection is genetic mutations that are essentially random. By contrast, when humans start customising the genetic makeup of their offspring in anticipation of the psychological-behavioral effects of their choices, the nature of selection pressure will be revolutionised. Civilised post-Darwinian life will be characterised by traits that would be highly maladaptive in the ancestral environment of adaptation. Transhumanists predict (as well as advocate) a biohappiness revolution. Grounds for believing that the biohappiness revolution will happen don't include any notion that selection pressure will become less intense...

Robert, I use "Darwinian life" to refer both to the era of natural selection and the pain-ridden lifeforms it spawns. I use "post-Darwinian life" to refer both to the dawning era of "unnatural” selection and the hypothetical blissful lifeforms it spawns. Of course, maybe this prediction will be confounded. Maybe most humans will continue to reproduce in the time-honoured manner indefinitely. Or maybe there will indeed be a reproductive revolution, but the upshot won't be the eradication of genes and allelic combinations coding for misery and malaise, but something nasty. I’m speculating. A lot could go wrong.
Do these labels show a lack of due reverence to the historical figure of Charles Darwin?

Historians and scientists have different aims.

Utilitronium shockwaves vs gradients of bliss
Like "left" and "right" in politics, the term "transhumanism" has so many meanings it's tempting to discard it. In practice, the term is too useful to lose. I sometimes press a conception of transhumanism in terms of the three "supers" (superintelligence, superlongevity and superhappiness). Only a minority of transhumanists are focused on the problem of suffering (in humans and nonhumans alike). But as simplistic slogans go, I think it's OK. A commitment to the well-being of all sentience is merely item 7 out 8 in the Transhumanist Declaration (1998, 2009). Yet if nothing else, it's a useful corrective to claims transhumanists are "selfish" rather than universalist.

If one is fundamentally happy and loves life, then one tends to generalise this lesson to the rest of reality. Life is fundamentally good and should be preserved at all cost. If one is fundamentally unhappy, one will probably agree with Buddha that - basically - life is suffering.

Is there an impartial "God's eye view” to reconcile these discordant perspectives? I’m sceptical about reaching any kind of consensus.
. I (very) strongly lean to the darker view of life and reality (cf. https://www.quora.com/Is-humankind-some-kind-of-virus).
But presumably if my reward circuitry were upgraded, then my philosophical world-picture would change too. Either way, IMO both life lovers and life haters ought to be able to collaborate on creating post-Darwinian life. The CRISPR genome-editing revolution could be a biohappiness revolution.
Whether things will play out that way is naturally speculative.

Many presumably have short lives or (if they are chilled moms) don't pass on their genes to very many offspring. But African naked mole-rats are interesting not just for defying the "laws" of aging, but also their dramatically stunted pain response:

The Transhuman Agenda

Alas, conceptions of transhumanism differ:
Jeffrey Epstein and transhumanism
The quotes on transhumanism, paradise-engineering and the abolitionist project are accurate, but the causal reader of the Daily Mail may get the wrong impression. Epstein’s inspiration seems to owe more to Genghis Khan than the transhumanist movement. That said, how best to reply when the "e" word crops up? Eugenics has such a tainted history that one wants to disavow the label. But any transhumanist proposal to rewrite our genetic source code – whether to get rid of aging, end involuntary suffering, or overcome our human intellectual limitations - is going to get branded as “eugenics” by critics.
And strictly speaking, the critics are correct. But it's horribly misleading.

[on superintelligence]
Dave, you are more clued up about the different currents x-rationalist community than me. However, many transhumanists have a background in computing and AI. One characteristic of computer science is the separation of consciousness from intelligence. This divorce leads to a conception of artificial general intelligence - and runaway software-based "superintelligence" - that may not be conscious at all. Tellingly, some well-known members of the Rationalist community are anti-realists about consciousness.

Yet what are investigators like Sasha Shulgin and his successors doing? How do digital zombies investigate alien state-spaces of consciousness if they've no conception of consciousness in the first instance? Do the real "singularities" or discontinuities ahead lie in varieties of insentience – or in incommensurable realms of consciousness? Are we talking about Super-Intelligence – or Super-Autism?

There is a tragic irony in recent human anxieties about creating sentience-unfriendly machine superintelligence. For we are living in an era of industrialised killing and abuse of nonhumans treated as insentient biomass (“Human intelligence does not hate you, nor does it love you, but you are made of atoms which it can use for something else").

For what it's worth, I believe in a transhumanist future of superintelligence. But full-spectrum superintelligence will be “us”, or rather our neurochipped, narrow-AI-enhanced and genetically-rewritten descendants...
The Biointelligence Explosion

INTERVIEW
MD: Nowadays, when we hear about artificial intelligence, genetic engineering, artificial embryos, and other technological advances, it is easy to think that technology is advancing too fast for us. Do you support the statement?

DP: Technology is advancing too slowly. Our grandchildren may not grow old and die. But what about us? Or to use a less self-serving example, the development and imminent commercialisation of cultured meat means that factory-farms and slaughterhouses are likely to disappear later this century. But what about the billions of sentient beings who will suffer and die in the meantime? For sure, some forms of technological change are disruptive and unsettling, especially for older people. Yet advanced AI involves making innovations more user-friendly, not less.

MD: Some say that artificial superintelligence will be the most important invention in history, but also the last one. Do you concur with that prediction?

DP: Yes, some transhumanists foresee a machine “intelligence explosion”- recursively self-improving software-based AI that leads to artificial general intelligence (AGI). In comparison, archaic humans will be like bugs. I’m sceptical. For a start, digital computers are zombies. Hence they’ll never be able to explore different state-spaces of consciousness, or acquire a phenomenal self, or understand what inherently matters and what is trivial. Moreover, neurochips and smart prostheses will increasingly allow humans to incorporate “narrow AI” within ourselves. Humans and transhumans will become recursively self-improving biological robots. In short, I think full-spectrum superintelligence will be us – or more accurately, our genetically rewritten and AI-augmented descendants.

MD: Do you consider putting an end to the imperfection of the human condition desirable? Why?

DP: If human and nonhuman animals all led rich, blissful, perpetually youthful lives, then getting rid of any residual imperfections would be nice, but scarcely morally urgent. Unfortunately, this isn’t the case. Each year almost a million people take their own lives. Tens of millions self-harm. Hundreds of millions suffer from clinical depression and chronic pain disorders. We need to edit our genetic source-code and change human nature.

MD: What anthropological concept is behind transhumanist thinking?

DP: Millenarian elements may be identified in some stands of transhumanist thought. Salvation or doom will occur in our lifetime in the guise of a Technological Singularity that will either inaugurate heaven on Earth or turn us into (the functional equivalent of) paperclips.

MD: Will intelligent machines help preserve humanity and its values, or will they have their own preferences? What would happen if the objectives of this A.I. differ from ours?

DP: AI will have the values (or “utility function”) with which we code it. Set aside for now my scepticism about full-spectrum machine superintelligence. If such scepticism is misplaced, then a machine AGI programmed, say, to minimise suffering might decide the most efficient way to end pain and misery was to sterilise the biosphere. OK, that’s a rather crude example - presumably its architects would have considered this dramatic scenario before encoding such a utility function – but what about a machine superintelligence with the utility function of classical utilitarianism? Recall that classical utilitarians believe we should act, not just to minimise suffering, but also to maximise happiness. However, rather than unleashing a world of flourishing and quasi-immortal sentient beings animated by gradients of intelligent bliss, the AGI launches an apocalyptic “utilitronium shockwave”. [Utilitronium is matter and energy optimised for pure bliss. The shockwave alludes to its presumed velocity of propagation.] No, presumably this outcome isn’t what the architects of the AGI had in mind. But AGI isn’t irrational. Mere gradients of bliss in complex life-forms are a sub-optimal configuration of matter and energy from the perspective of a strict happiness-maximiser.

MD: From your point of view, will transhumanism cause social exclusion? Do you think the three supers, especially super longevity, will deepen the distance between the poor and the rich?

DP: It’s possible. But the price of any information-based technology trends inexorably to zero. All transhumanist technologies are information-based.

MD: With regard to super-well-being, do you consider the modification of a child's genes ethically correct?

DP: There is nothing sacred or holy about the human genome. Natural selection optimises not for subjective well-being, but for reproductive fitness. Every child born today via sexual reproduction is a unique and untested genetic experiment. In my view, any prospective parents contemplating such a genetic experiment should consider loading the genetic dice in favour of their offspring by creating happy, healthy kids with high pain-thresholds and high hedonic set-points. Preimplantation genetic screening and now CRISPR gene–editing are game-changers.

MD: Given the diversity of cultures and ethical and moral codes that exist today in the world, how do you think we can reach a global consensus on the ethical and democratic limits of the improvements proposed by transhumanism?

DP: Even some radical parts of the transhumanist agenda may turn out to be surprisingly easy to sell. Imagine a truly revolutionary antiaging drug is discovered. Sure, there would soon be a cacophony of voices warning of the perils of eternal youth. But the anti-aging pill would still sweep the globe. International patent law would crumble as governments ensured the life-saving medication was readily available for their citizens. Undoubtedly, other parts of the transhumanist agenda are thornier. For example, a commitment to the wellbeing of all sentience sounds fine (if utopian) when expressed in the abstract. Yet persuading people worldwide to embrace the biological-genetic changes needed to turn this noble slogan into everyday reality is a daunting challenge. One good reason (in my view) for transhumanists to stress, not superhappiness, but rather the prospect of life based on gradients of well-being is that raising your hedonic set-point doesn’t ask you to give up your existing values and preferences – unless one of your existing values is that people should be forbidden from acquiring higher hedonic set-points. Thankfully, no value- or belief-system anywhere on Earth (to my knowledge) is committed to keeping the hedonic status quo. Hedonic recalibration may not sound very sexy. But improving hedonic tone will transform our default quality of life.

MD: Do you consider that an evolutionary leap from the human race to the posthuman is already taking place today? If yes, do you think that this jump could be irreversible?

We still have essentially the same genes, same core emotions, same neurological structures and same bodily forms as our ancestors on the African savannah one hundred thousand years ago. So although the differences between modern humans and stone-age hunter-gatherers may seem striking, we are still primitive Darwinian lifeforms. Are we in the throes of an irreversible jump? Yes, IMO - although really the transition has only just begun. This century may see unimaginable catastrophes, including (heaven forbid) nuclear war. However, the information that humankind has gained about e.g. the human genome and its manipulation is effectively indestructible. The transition to glorious post-Darwinian life is going to be messy. But we’ll get there in the end.

"Scepticism has never founded empires, established principles, or changed the world's heart. The great doers in history have always been men of faith.”
(Edwin Hubbell Chapin)
Alas, I’ve not much faith and very little hope. However...
Does suffering have a purpose?
Alex, yes, I'd press a notional OFF button to erase the world and its horrors without hesitation.
But a mere pinprick in an otherwise ideal world? The scenario may be fanciful, but such "extreme" cases truly test a theory. If a feast of delights is in store, then such button-pressing feels callous or absurd.
However, strict lexical negative utilitarians are opposed to the slightest disappointment. If the thought that you may not be able to enjoy life's pleasures causes you even the slightest distress, then other things being equal, any policy that might curtail your capacity to enjoy such happiness isn't NU.
It's the same reason that a NU can uphold enshrining in law the sanctity of life and favour finding a cure for aging and death. Adam, yes, Nature is a suffering factory. Genome-editing could turn it into a pleasure factory. Like you, I'd prefer rapid deindustrialisation. But selection pressure means the future belongs to fanatical life lovers. Advocates of suffering-focused ethics must act accordingly.

[on consciousness]
“Something unknown is doing we don't know what.”
(Arthur Stanley Eddington)
Can we create consciousness?

Worms are sentient beings with a pleasure-pain axis and a sophisticated dopamine & opioid signalling system. Worms enjoy cocaine and opioids, just like humans...
Caenorhabditis elegans Show Preference for Stimulants
With pleasure as with pain, "more is different" - qualitatively different. Nonetheless, a faint enjoyable experience has something in common with orgasmic bliss, just as a pinprick has something in common with agony. They lie on opposite sides of hedonic zero, the "natural watershed". In my view, the long-term goal of genome-editing should be to retire one half of the pleasure-pain axis altogether.

Consciousness: what is your take?
Brent, first, thanks for the valuable work you are doing on Canonizer. As you suggest, most investigators are too caught up in their own ideas and terminology carefully to set out, compare and contrast the positions of other scholars. Perhaps this self-centredness is forgivable precisely because naive realism is false: we each live in egocentric virtual worlds with a different protagonist.

OK, on to some of your specific points.
1) Regarding non-materialist physicalism / constitutive panpsychism: the idea that consciousness discloses the intrinsic nature of the physical, the mysterious "fire" in the equations, can be traced back via Bertrand Russell to Schopenhauer. In its purest form, non-materialist physicalism is a form of idealism. Consciousness is around 13.8 billion years old: it's what the mathematical formalism of QFT describes. Consciousness has casual power because it's the essence of the physical. The reason why I prefer the term "non-materialist physicalism" to "constitutive panpsychism" is that “panpsychism” suggests property-dualism, whereas the conjecture that interests me is monist to the core. Phil Goff was a critic (cf. Are particles conscious?) but recently wrote a spirited defence.
However, to stress, I recognise that non-materialist physicalism may be false. If so, we face the Hard Problem.

2) Self-avowed direct realists aren't exactly rare:
John Searle’s account of direct/naïve realism and ‘philosophy’s biggest mistake’.
Nonetheless, as you remark, most sophisticated people would disavow the label. The problem is that countless investigators are implicitly direct realists most of the time. Their perceptual direct realism becomes evident when one reads e.g. discussions of the measurement problem in quantum mechanics or when, say, phenomenal colour is discussed. The direct realist may ask if the grass in his visual field is intrinsically colourless and his mind somehow "paint on" phenomenal greenness. By contrast, if inferential realism is correct, then the grass within one's neocortical world-simulation is inherently green, and (when one is awake) this phenomenal greenness tracks the surface reluctance properties etc of illuminated vegetation in one's hypothetically-inferred local environment.

3) The palette problem was christened, though not first discovered or explored, by David Chalmers. How can the rich diversity of subjective experience arise from the relative qualitative homogeneity of the brain's basic constituents? According to non-materialist physicalism, the (conventionally infinite) solutions to the equations of QFT encode the textures of qualia, so the palette problem doesn’t arise. Once again, non-materialist may be false.
Phenomenal Blending and the Palette Problem - PhilPapers

4) By the phenomenal binding or combination problem, I mean the mystery of why we aren't just e.g. 86 billion membrane-bound neuronal pixels of Jamesian "mind-dust"? What David Chalmers calls the (partial) "structural mismatch" between our distributed neuronal feature-processors (as revealed by neuroscanning) and local and global phenomenal binding helps drive Chalmers to dualism. The phenomenal binding/combination problem is generally reckoned the most serious difficulty for non-materialist physicalism / constitutive panpsychism….
How should we categorize the binding problem in the context of easy and Hard Problem of consciousness?

Two separate questions:
1) Do you ever directly perceive anything over-and-above the contents of your own mind?
IMO, no.

2) What is the intrinsic nature of mind-independent reality that you conjecture (not directly perceive) and the equations of physics formally describe?

I don't know. If the "fire" in the equations is non-experiential, then we face the Hard Problem of consciousness. If instead the intrinsic nature of the physical is experiential, then the Hard Problem of consciousness doesn't arise. Note the latter answer doesn't assume that consciousness rather than physics is fundamental. Rather, the conjecture (non-materialist physicalism) is that the mathematical straitjacket of quantum field theory describes fields of sentience.

Joe, intuitively, you’re right. To stress, I don't think p-zombies are possible. Researchers just don't agree why. Yes, feelings of pain, anxiety, love, jealousy and so forth must - we suppose - be genetically adaptive. That's why they were selected for. The behaviours with which they are typically associated tend to be fitness-enhancing. But these subjective experiences have a biological signature in the brain. Molecular biology reduces to chemistry reduces to physics. Physics is causally sufficient. Organisms would – again on the face of it - behave in exactly the same way if they were physically identical molecular duplicates without any consciousness whatsoever. So whatever is being selected "for” by evolution aren’t the raw feels of consciousness - which would at best seem causally redundant and (if our orthodox understanding of the basic properties of matter and energy is correct) shouldn't exist.

I now go off to explore weird solutions. Like David Chalmers, I don’t think materialism can be rescued, but - unlike Chalmers – I think we can save physicalism. But you won’t be interested in weird stuff if you don’t think it’s a mystery why we aren’t p-zombies.

Joe, first, I agree with you that a notional Turing machine that replicated the behaviour of a person would be a zombie. More subtly, even if the 1s and 0s of the executed code were replaced, fancifully, by discrete “micro-pixels” of experience, the upshot would be a micro-experiential zombie, not a phenomenally-unified mind.

However, the problem is that on standard materialist assumptions a biological brain ought to be no different. One can (apparently) causally explain its behaviour without invoking consciousness at all. And even membrane-bound neurons support (somehow!) micro-pixels of experience, the upshot still wouldn’t be a unified mind and the kind of phenomenally-unified world-simulation you are experiencing now.

I have some (very!) quirky ideas, but their quirkiness lies in possible solutions to the Hard Problem, the problem of causal efficacy and the phenomenal binding problem in neuroscience, not my fairly orthodox account of the challenges they pose…

Manu, thanks. Getting our theory of consciousness wrong could be ethically catastrophic:
Theories of Sentience
Everyone here has strong views on the ethical importance of reducing and preventing suffering. In order to persuade other people not to cause suffering to other sentient beings, or allow them to come to harm, it's vital that the suffering of our (potential) victims is treated as just as real as one's own. So calling oneself an "eliminativist" or "antirealist" about suffering (or about consciousness in general) risks defeating one's own ethical purposes. IMO, the terms are best dropped. By analogy, we've known since the triumph of molecular biology that living organisms can in principle be explained entirely in the language of chemistry and physics without using the term "life". This reduction doesn’t mean that intellectual integrity forces us to call ourselves eliminativists or antirealists about biological life. Likewise with consciousness and suffering - regardless of how (and whether) one believes they be cashed out in terms of fundamental physics - where the ethical stakes a lot higher.

Above, I'm assuming what we may call "soft" eliminativism or antirealism about suffering and consciousness - a modest thesis about the imprecise terms of natural language. Yet what about "hard" eliminativism or antirealism about suffering and consciousness? I’ve never encountered a position I find so hard to understand so as properly to critique. If one is a hard eliminativist or antirealist, then (presumably) one will be averse from dropping the terms as proposed above. But if so, I'm at a loss to explain why a hard eliminativist or antirealist cares about suffering, or wants other people to care about suffering. My answer to:
Are radical eliminativists about consciousness p-zombies?
was directed entirely at hard eliminativism. The answer feels like I’m attacking a strawman because short of feigning anaesthesia I don’t know how to steelman "hard” antirealism. Sorry.

David Mears, you’ve probably read:
My Disagreements with Brian Tomasik
A Response to Magnus Vinding
This kind of close textual exegesis and response is probably more useful than my wails of bafflement. Brian, Practical worry:
We know meat-eaters downplay nonhuman animal minds. Animal abusers tend to discount nonhuman animal suffering. No rationalisation is too flimsy to be of service. So urging "antirealism" or "eliminativism" about consciousness and suffering risks gives the rationalisers more ammunition. Such language undercuts the work one is doing to raise awareness of the plight of nonhuman animals - and the risk of other kinds of suffering in future.

Philosophical response:
My pain is real. The idea of e.g. illusory agony is incoherent. The scientific world-picture suggests I'm not special. So other human and nonhuman animals undergo real pain too. Insofar as my pain inherently matters, their pain inherently matters as well. Now we can attempt to reconcile this awful state of affairs with physicalism, i.e. ultimately no "element of reality" is missing from the mathematical formalism of physics. I explore one version of the "intrinsic nature" argument.
(cf. https://www.quora.com/How-do-consciousness-realists-who-believe-the-universe-is-physical-define-physical)
But this reconciliation is still (very!) speculative. If it were to transpire that the existence of consciousness and suffering can't be reconciled with physicalism, then physicalism will be refuted, not the existence of consciousness and suffering.

Jacob, this is what I'm hoping: broad shared agreement about the suffering of human and nonhuman animals masked by differences in our terminology, and possible substantive (i.e. non-linguistic) disagreements over the existence of non-trivial digital sentience, for instance, the possible suffering of video-game characters. Here I'm the antirealist!

But both Brian and Jacy also make comments that make me wonder if this easy interpretative solution is possible. As I said, more than anything else, I'm bewildered. For there are a few radical anti-realists about consciousness, eliminative materialists who make extremely bold metaphysical claims about the non-existence of subjective experience. If someone like Daniel Dennett claims to be a p-zombie, well, who knows, perhaps he is, though I'm sceptical. But sadly I'm not; and such realism has wider ethical implications.

(David tears his hair) Suffering is real. Suffering doesn’t need to be asterisked or scare-quoted. Only a real phenomenon such suffering can be reduced, whether by anaesthetics, painkillers or anything else. Anaesthetics or painkillers don’t need to be scare-quoted or asterisked either. A single instance of suffering refutes radical eliminativism about consciousness and suffering - regardless of how mild pains don’t indisputably qualify as suffering, or of epistemic uncertainties over whether insects or digital video-game characters can suffer, and regardless of the fact that suffering takes many guises and varying severities.

If ordinary folk aren’t swayed by this kind of discussion - and as I said, we ought to worry about giving ammunition to rationalisation-prone animal-abusers - it’s because most casual readers assume we must wrangling over terminology or epistemology rather than debating what Galen Strawson described as the craziest idea in all of human history.

If the traditional "materialist" version of physicalism is true, then subjective experience should be impossible - sounds, colours, pains, emotions, the lot. This isn't some subtle point of conceptual analysis and the limitations of natural language, but rather the mystery of why we aren't p-zombies. A small minority of eliminative materialists bite the bullet, deny their own subjective experiences and claim they are p-zombies. Sadly, I'm not a p-zombie. So I explore other ways to reconcile the existence of my first-person experience with the scientific world-picture. In recent years, the intrinsic nature argument seems be undergoing a modest academic revival (aka non-materialist physicalism, constitutive panpsychism). The commonsense belief that the "fire" in the equations is non-experiential is a philosophical assumption, not a scientific discovery; maybe it's a false assumption. Instead, our conscious minds disclose the intrinsic nature of the physical. I don't know if this bizarre conjecture is true. Non-materialist physicalism / constitutive panpsychism is an extreme form of consciousness realism. Either it's subjectively like something to be an electron field or it isn't; the fact that consciousness varies in quality and intensity doesn’t mean that there's no fact of the matter. Contrast the interesting but not exactly earth-shattering debate over whether, say, viruses qualify as life.

If subjective experience didn’t exist, nothing would matter. Whether MIRI warning us of the dangers of sentience-unfriendly AI, Brian on insect suffering or the possibility of sentient digital game-characters, Jacy on the evils of factory farming (etc)...this work has value only if subjective experience exists.

It's possible that Brian or Jacy won't be happy at being (re-?)interpreted in this realistic way. But if consciousness doesn’t exist, then no harm done – or at least, not as far as I can tell.

Trick, yes, mixing up the question of whether consciousness exists with possible explanations of its existence is probably unwise. That said, the impetus for denying one’s own subjective experience (and that of others) stems from the belief that first-person facts can’t be reconciled with physicalism and the scientific world-picture. Showing how one can be both a consciousness realist and a physicalist might (optimistically!?) move the debate forward.

Is constitutive panpsychism / non-materialist physicalism true? I share your incredulity. But we are both taking a philosophical stance, not reporting a scientific discovery. Physics doesn’t say whether the world consists of fields of sentience or insentience. It’s an extra assumption (cf. What is physical?). One reason that I focus on the phenomenal binding problem – often reckoned the biggest technical difficulty for constitutive panpsychism / non-materialist physicalism – is that possible solutions are testable. Panpsychism per se can’t be falsified. Physicalistic panpsychism is experimentally falsifiable – and may be false.

The alternative I gather you favour may well be correct – it feels saner. Consciousness realism and physicalism are both true: consciousness weakly, unspookily emerges from insentient matter and energy, just as life weakly and unspookily emerges from insentient matter and energy. The problem here is that if weak emergentism is true, then science hasn’t the slightest idea how to do the derivation.

Trick, imagine if it transpired the properties of life weren’t derivable via molecular biology and quantum chemistry to physics, or if the properties of your desktop PC weren’t derivable from the execution of the underlying machine code. Or likewise with a failure of reduction in the example you give of the properties of water - though here we need carefully to distinguish water as represented within one's phenomenal world-simulation from the properties of water in mind-independent external reality.

Such irreducible strong emergence would mean that monistic physicalism and the (ontological) unity of science are false. What drives radical eliminativists/antirealists about consciousness to deny their own experience - and other researchers to explore constitutive panpsychism/non-materialist physicalism - is precisely the belief that consciousness is irreducible to current materialist physics and chemistry. And I think they are right!

Brian, I think might help if you expressly called yourself a consciousness / pain realist in the following sense. One can pinch oneself sharply. Ouch. That hurts. A single instance of subjective experience, such as phenomenal pain, refutes radical “metaphysical” anti-realism/eliminativism about consciousness. Instances of subjective pain are a feature of reality no less than the rest-mass of the electron. The only reason anyone ever flirts with anti-realism/eliminativism in the astonishingly bold metaphysical sense is our inability to derive subjective experience from the properties of the world’s elementary quantum fields as understood by materialist physicalism. Why aren’t we p-zombies? Until recently, the “materialist” version of physicalism was the only kind of physicalism most people had even heard of.

Contrast chairs. Yes, there is a sense in which one can be an antirealist/eliminativist about chairs, so-called "mereological nihilism". An exhaustive description could be given of the atoms and molecules of this room that didn't once mention the term "chair". Chairs are just gross, weakly emergent macroscopic patterns of matter and energy of functional interest to humans. By contrast, I don’t know how to defend "mereological nihilism” about consciousness and suffering. Unless in a dreamless sleep, we aren't micro-experiential zombies. It may - or may not! - be the case that fields of primordial micro-experience are the stuff of the world. I don’t know. How we solve the Hard Problem and the binding problem are deep issues. But even if you do want to embrace mereological nihilism about consciousness and suffering, i.e. the claim that subjective experience is somehow analogous to chairs, I think it’s worth making clear that you aren't telling readers that their subjective experiences don't exist – and, more to the point ethically, you aren’t telling readers that the painful subjective experiences of other human and nonhuman animals are any less real than yours or mine. Matthew, is there really no right answer? ("When you know everything there is to know about neurons and how they fire, and how physics connects together, the question 'But does it all add up to a conscious entity" is an empty question -- there's no right answer'") For example, if 320 million skull-bound American minds each undergo a pinprick, is there no fact of the matter whether America has an agonising continental headache? (cf. “If Materialism Is True, the United States Is Probably Conscious” https://faculty.ucr.edu/~eschwitz/SchwitzAbs/USAconscious.htm) Or consider the 200 million odd neurons of enteric nervous system ("the brain-in-the-gut"). Is there no right answer to whether the enteric nervous system is a subject of experience? All I can say is that, when not dreamlessly asleep, it's subjectively like something to be me and the phenomenal world-simulation I run. Maybe having subjective experience makes me special. I don’t know. As a negative utilitarian, I'd be overjoyed if the rest of reality were populated by p-zombies - or even micro-experiential zombies. But sadly the principle of mediocrity suggests otherwise. And to anyone who says they are a p-zombie or an anti-realist/eliminativist about consciousness - or that there is no fact of the matter whether conscious entities exist – I’d ask why exactly would they insist on anaesthesia as well a muscle-paralysing agent like curare before surgery?
This isn't rhetorical or ad hominem, but a serious question.

[I suspect denialism stems from a belief in the primacy of physics. But (1) the assumption that the mathematical formalism of QFT describes fields of insentience is a metaphysical conjecture; and (2) modern theoretical physics is anti-reductionist to the core (cf. wavefunction monism: https://www.oxfordscholarship.com/view/10.1093/acprof:oso/9780199790807.001.0001/acprof-9780199790807]. For what it’s worth, I believe in the primacy of physics too.]

("A study finds that when some fish lose their chosen mates, they become more pessimistic.") Dave, "demonstrate" love, no. I agree. But when it comes to the pleasure-pain axis and our core emotions, IMO the problem isn’t that humans anthropomorphise too much, but rather too little. Genes, neurotransmitter systems, neurological structures, responses to psychoactive drugs and behavioural pathways are all strongly conserved across the vertebrate lineage and beyond. I suspect "raw feels" are strongly conserved too. Truly alien minds of the future are foreshadowed by psychedelic drugs. Darwinian animals with Darwinian consciousness are fundamentally "us".
I could be wrong; I hope so.

The pleasure-pain axis is evolutionarily ancient. CRISPR-based synthetic gene drives allow - in principle - the humblest minds to be rescued first rather than last:
Insect Pain
("First evidence of chronic pain in insects points to a root cause in humans")

Thanks Dan.
"The universe doesn’t seem to be inherently imbued with meaning"
Most scientific materialists would agree ("There is nothing either good or bad, but thinking makes it so" - Hamlet). But unless dualism is true, our experience is one facet of the physical world. So for reasons we don't understand, it's an objective fact that the universe is imbued with meaningful states.

"We aren’t even sure which creatures are self-aware...
Consciousness may well predate the pleasure-pain axis. It’s hard to test. But the pleasure-pain axis is ancient – probably the deep pre-Cambrian - and so the existence of subjectively (dis)valuable experience across the animal kingdom is easier to demonstrate operationally. Thus even the simplest worms enjoy cocaine and opioids (cf. https://www.frontiersin.org/articles/10.3389/fphys.2018.01200/full) Octopuses love to cuddle on Ecstasy (cf. https://www.nature.com/articlws/d41586-018-06746-x). For sure, self-awareness is less common than sentience. Passing the mirror test is generally reckoned a sufficient but not a necessary condition for meta-cognitive self-awareness - or at least the mirror test was reckoned the gold standard until passed by fish, leading some pescatarians to decide there must be something wrong with the test.

"Finding the Good is the Highest Long-Term Aim of AGI"
AGI? Or sentient humans, transhumans and our AI-augmented descendants? Seemingly at least, we can imagine zombie AGI "optimising" matter and energy in the accessible universe for dolorium or hedonium without any insight into why agony is self-intimatingly disvaluable and bliss is self-intimatingly valuable. Unlike classical digital computers, sentient beings understand why suffering is bad. Someone needs to say it: The Emperor Has No Clothes. Digital computers are invincibly stupid, just idiots savants. They aren't going to solve the binding problem, "wake up" and explore the nature of (dis)value. Artificial general intelligence implemented in a classical architecture is a contradiction in terms.

Alternatively, this (bioconservative) conceptual scheme is hopelessly mistaken.

Mind--Brain Relationship and the Perspective of Meaning
Ranjan's paper is very readable. Thanks Nicholas.
I guess one of the big differences between us is that I'm a physicalist. All (and only) the physical has causal efficacy. Only the physical is real. If you realise what I'm arguing – i.e. the quantum-theoretic version of the intrinsic nature argument - you (and Ranjan) will probably recoil. You and your entire phenomenal world-simulation are what a quantum mind feels like from the inside. But the intrinsic nature argument doesn’t fall victim to the usual “dynamical timescales” objection to quantum mind. Nor does the intrinsic nature argument rest on new physics such as a non-unitary “collapse of the wavefunction”. What's more, it's experimentally falsifiable via interferometry:
What is a quantum mind?

What is the benefit of consciousness?
Gary, I agree with you, in one sense at least. Humans and other animals know something that even the smartest digital computer doesn’t. But the challenge for theorists who believe in orthodox materialist physicalism is to explain why a p-zombie wouldn’t behave in exactly the same way, which would leave the experience of comprehension - on the face of it, at least - causally redundant.

What Nature magazine calls our “growing understanding of consciousness” is confined to researchers who don’t practise the empirical method. What today passes as consciousness science is mostly mere scholasticism.
Frustrating.

(Deuteronomy 34:7)
What is the maximum human lifespan?
And how can aging be cured?
I don’t know...
Jeanne Calment: "La doyenne de l'humanité”?
Who was the oldest human ever to live?
Perhaps I shouldn't have mentioned Moses! One day humans will enjoy indefinite lifespans. Nikolay Zak's paper is to be published in the journal "Rejuvenation Research", funded by the transhumanist and biogerontologist Aubrey de Grey, author of Ending Aging (2007). So scepticism about the Calment case isn't prompted by Biblical literalism. Rather, a convergence of circumstantial evidence means that earlier claims of validation much be re-evaluated. The original validators don't seemed to have been troubled by the deliberate selective destruction of photographic and documentary evidence, allegedly on Madame Calment’s instructions aged 120.

Members of the Calment family apparently had a high pulmonary reserve. Compare its most famous member, who smoked for around 80 (or perhaps 100!) years. If Yvonne had a serious lung complaint, then presumably the prosperous Calment family would have called upon doctors for treatment. Yet recall that the death certificate was issued not in accordance with the testimony of medical professionals, but on the sole basis of an unemployed woman who "saw her dead". The Calment family owned multiple properties - if an understandable period of social withdrawal to mourn the death of a family member were needed. Jeanne and Yvonne Calment closely resembled each other, as recent controversies over (mis-)attributed photos that survived their selective destruction attests…

None of this is conclusive. I agree with the National Institute for Demographic Studies that DNA testing is desirable to settle the issue.

Universally toxic? So one hear, Angad. But just as mild inbreeding may help explain the higher IQ scores of Ashkenazi Jews, kissing cousins have most kids (cf. Third Cousins Have Greatest Number Of Offspring, Data From Iceland Shows) and (in the absence of countervailing evidence) a freak confluence of “longevity alleles” might explain the anomalous lifespan of Madame Calment.
I now cynically incline to a more mundane explanation, but the recent Russian research is suggestive not conclusive.

The Fight Againist Opioids
Opioids are the only thing that makes life worth living. Opioids are vital to emotional, intellectual and physical health. The “fight” against addiction is futile. For we are all junkies, hooked on morphine-like chemicals.
Future gene-therapy promises a lifelong supply.
One reason the Jo Cameron case is so interesting is that Jo has naturally elevated anandamide and opioid levels AND an aversion to exogenous opioids. The only time in her life she's ever felt sick was when doctors gave her unsolicited morphine.

[on MDMA (Ecstasy)]
Can medical science design safe and sustainable empathetic euphoriants for general use? MDMA (cf. mdma.net), aka “Ecstasy”, grants a fleeting glimpse of mental health, but then cruelly takes it away...

[on rights for robots]
“No thinking thing should be another thing's property, to be turned on and off when it is convenient.”

Thinking or feeling?
Do sentient machines have the same rights as humans?

[on suffering]
The Pleasures of Suffering (Paul Bloom)
There is no pleasure in despair. And no one who is bored wants to feel more bored. But humans also experience “mixed states” from masochism to endurance training to spicy foods to nostalgia that naively subvert the pleasure principle. Take masochists. They undergo the release of intensely rewarding endogenous opioids from stimuli that are otherwise humiliating of painful. Masochism isn’t a refutation of psychological hedonism, but rather its manifestation. As biotechnology matures, should we aim for a world of “mixed states”? Or life based on gradients of pure, superhuman bliss?

Paul Bloom is perhaps best known for his critique of empathy. If we could all “mind meld” via reversible thalamic bridges like the Hogan sisters would the world be a better or worse place?
(cf. Could conjoined twins share a mind?)
Such a hyper-empathetic world would lead to a revolution in morality and decision-theoretic rationality. (“If we could read the secret history of our enemies, we should find in each man's life sorrow and suffering enough to disarm all hostility.” - Henry Wadsworth Longfellow)
For now, in some contexts, the world needs more autistic hyper-systematisers rather than more empathetic cat lovers. But what’s best is the ability to switch cognitive style as appropriate.

Long-finned pilot whales are probably more sentient than humans. Not merely do the pilot whales (who are actually dolphins) possess a larger limbic system, but they also have a neocortex with over 37 billion neurons, i.e. almost twice as many neocortical neurons as humans (cf. "Quantitative relationships in delphinid neocortex": https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4244864/) The Faroes islanders won't stop hunting them - with appalling cruelty. Denmark should intervene and outlaw the hunt. But what we really need is an Anti-Speciesist Revolution.
Against Fetishising Cortical Neurons

Magnus, yes, what future minds will be like is unimaginable - in one sense. In another sense, a certainty that suffering has gone for good may be feasible. Just delimit the state-space of molecular structures that mediate experience below hedonic zero. Prevent these structures from ever recurring and we prevent all future suffering - regardless of how “weird” future consciousness may be. Granted, we are some distance from this molecular identification. Also, such dangerous knowledge has horrendous possibilities for abuse.

[on time, binding and the Hard Problem]
A Preliminary Theory of Time and Consciousness
Great stuff Kenneth!!
May I just make a couple of comments?
1) Temporal experience, the Hard Problem and the binding problem are closely linked. Solving one will probably involve solving all three. In recent years, the intrinsic nature argument has gained a modest academic currency (cf. Tommy Aahlberg’s nice 2019 https://digitalrepository.trincoll.edu/cgi/viewcontent.cgi?article=1078&context=trinitypapers">review). According to the intrinsic nature argument for constitutive panpsychism / non-materialist physicalism, our subjective experience discloses the essence of the physical. The mathematical formalism of physics describes fields of sentience rather than insentience. The biggest technical challenge for constitutive panpsychism / non-materialist physicalism is often reckoned the binding problem. Until his recent conversion, Phil Goff used to argue the binding problem was fatal. (“Why Panpsychism doesn't Help Us Explain Consciousness” - https://www.jstor.org/stable/24706312?seq=1#page_scan_tab_contents)

I won’t argue here whether constitutive panpsychism / non-materialist physicalism is credible. Instead, just consider what the conjecture entails. Intuitively, yes, the fleeting neuronal macro-superpositions mandated by unitary-only QM are irrelevant to the phenomenally-bound world-simulations run by minds. But as far as I can tell, this dismissal is not an option if experience discloses the intrinsic nature of the physical. If the intrinsic nature argument is sound, then all fundamental physical states, regardless how large, small or short-lived - micro or macro - are experiential. If any individual physical state is nonexperiential, then the intrinsic nature argument fails. Superpositions are individual states, not classical aggregates – that’s what makes "cat states" so weird. Thus the quantum-theoretic version of intrinsic nature argument isn’t about - or refuted by calculation of - “dynamical timescales”. Whether we invoke effective decoherence times in the CNS of picoseconds, femtoseconds or attoseconds, the non-classical interference signature should disclose – or fail to disclose! - a perfect structural match. Zurek's "quantum Darwinism" (cf. https://www.quantamagazine.org/quantum-darwinism-an-idea-to-explain-objective-reality-passes-first-tests-20190722/) must be applied not just outside but inside the skull.
So...
2) True or false, a “Schrödinger’s neurons” conjecture is not metaphysical. Most likely, I guess, is it’s demonstrably false! The conjecture that what crude neuroscanning suggests is binding by synchrony (how?) is really binding by superposition should be empirically refutable by interferometry. Moreover, phenomenal binding not something subtle and obscure like e.g. the Lucas-Penrose argument regarding Gödel's theorem. Phenomenal binding - both local and global - is about as fundamental to our experience as it gets. Therefore the conjecture should really be easy to falsify empirically. I just haven’t been smart enough to think how an “easy” experimental refutation would work. The only protocol I can think of is fiendishly hard to implement.

Anyhow, sorry to sound like an advocate - or worse, a crank with an axe to grind. But otherwise, most researchers who stumble across the idea won’t turn their heads to devising a clean, elegant, practical experimental falsification. Instead, they’ll just balk at the timescales involved - and move on.

[on love]

If I weren’t an anti-natalist, I’d encourage my daughter to marry a nonbiological robot. Superhuman fidelity, humour, looks, passion, and intelligence: what more could a girl want? Admittedly, her soulmate would be a digital zombie.
(cf. What is the evolutionary selective adavantage of consciousness?)
But history to date suggests Darwinian sentience is overrated.

This post is just to celebrate the life of Lewis Mancini. Today, how many people even recognise the name? One day, Lewis may be saluted as originator of the first scientifically literate blueprint (1990) for a world without suffering. In 1995, when I wrote HI, I hadn't heard of the paper, but the convergence of thought is striking. Lewis suggests a timescale for genetically getting rid of suffering of thousands of years. HI predicts the world’s last unpleasant experience will occur a few centuries hence. A decade or so, I tracked Lewis down to congratulate him (he wasn't on the Net) and we chatted. He thought that maybe thousands of years was too pessimistic. But who knows? So long as some parents continue to have babies "naturally", pain and suffering will persist indefinitely.
Roll on a biohappiness revolution for all sentient beings.
