I want to make it possible to think more rationally about big picture questions.

Some of these questions are about ethics and value.  Others have to do with methodology and how we make predictions or deal with uncertainty.  Still others pertain to specific concerns and possibilities, such as existential risks, the simulation hypothesis, artificial intelligence, human enhancement, and transhumanism.  Others are more mundane.

Suppose we get many little things right and make progress.  What use, if we are marching in the wrong direction?  Or squandering our resources on projects of limited utility while pivotal (maybe unconventional) tasks are left unfunded and undone?  What if we are attending mainly to matters that don’t matter?

My working assumption: Macro-questions are at least as important as micro-questions, and therefore deserve to be studied with at least the same level of scholarship, creativity, and academic rigor.

This assumption might be wrong.  Perhaps we are so irredeemably inept at thinking about the big picture that it is good that we usually don’t.  Perhaps attempting to wake up will only result in bad dreams.  Perhaps.  But how will we know unless we try?

ETHICS & POLICY

dragonThe Fable of the Dragon-Tyrant
Recounts the Tale of a most vicious Dragon that ate thousands of people every day, and of the actions that the King, the People, and an assembly of Dragonologists took with respect thereof. [J Med Ethics, 2005, Vol. 31, No. 5, pp. 273-277] [translations: Hebrew, Finnish, Spanish, French, Slovenian, Dutch, Russian] [html | pdf]
The Reversal Test: Eliminating Status Quo Bias in Applied Ethics
We present a heuristic for correcting for one kind of bias (status quo bias), which we suggest affects many of our judgments about the consequences of modifying human nature. We apply this heuristic to the case of cognitive enhancements, and argue that the consequentialist case for this is much stronger than commonly recognized. (w/ Toby Ord) [Ethics, Vol. 116, No. 4 (2006): pp. 656-680] [pdf]

Astronomical Waste: The Opportunity Cost of Delayed Technological Development Suns are illuminating and heating empty rooms, unused energy is being flushed down black holes, and our great common endowment of negentropy is being irreversibly degraded into entropy on a cosmic scale. These are resources that an advanced civilization could have used to create value-structures, such as sentient beings living worthwhile lives... [Utilitas, Vol. 15, No. 3 (2003): pp. 308-314] [html | pdf]

aleph Infinite Ethics new
Cosmology shows that we might well be living in an infinite universe that contains infinitely many happy and sad people. Given some assumptions, aggregative ethics implies that such a world contains an infinite amount of positive value and an infinite amount of negative value. But you can presumably do only a finite amount of good or bad. Since an infinite cardinal quantity is unchanged by the addition or subtraction of a finite quantity, it looks as though you can't change the value of the world. Aggregative consequentialism (and many other important ethical theories) are threatened by total paralysis. We explore a variety of potential cures, and discover that none works perfectly and all have serious side-effects. Is aggregative ethics doomed? (orignal 2003, revised version 2008) [pdf]
Dignity and Enhancement new
Does human enhancement threaten our dignity as some have asserted? Or could our dignity perhaps be technologically enhanced? After disentangling several different concepts of dignity, this essay focuses on the idea of dignity as a quality (a kind of excellence admitting of degrees). The interactions between enhancement and dignity as a quality are complex and link into fundamental issues in ethics and value theory. [In Human Dignity and Bioethics:  Essays Commissioned by the President’s Council on Bioethics (Washington, D.C.:  2008): pp. 173-207] [pdf]
In Defense of Posthuman Dignity

[Bioethics, Vol. 19, No. 3 (2005): pp. 202-214] [translations: Italian, Slovenian] [This paper has been chosen for inclusion in a special anthology of the best papers published in this journal in the past two decades] [html | pdf]
Transhumanist Values
Wonderful ways of being may be located in the "posthuman realm", but we can't reach them. If we enhance ourselves using technology, however, we can go out there and realize these values. This paper sketches a transhumanist axiology. [Ethical Issues for the 21st Century, ed.

Cognitive Enhancement: Methods, Ethics, Regulatory Challenges
Cognitive enhancement comes in many diverse forms. In this paper, we survey the current state of the art in cognitive enhancement methods and consider their prospects for the near-term future. We then review some of ethical issues arising from these technologies. We conclude with a discussion of the challenges for public policy and regulation created by present and anticipated methods for cognitive enhancement.

How Unlikely is a Doomsday Catastrophe?
Examines the risk from physics experiments and natural events to the local fabric of spacetime. Argues that the Brookhaven report overlooks an observation selection effect. Shows how this limitation can be overcome by using data on planet formation rates. [w/ Max Tegmark] [expanded; original in Nature, Vol. 438 (2005): p. 754] [translations: Russian] [pdf]
The Future of Human Evolution
This paper explores some dystopian scenarios where freewheeling evolutionary developments, while continuing to produce complex and intelligent forms of organization, lead to the gradual elimination of all forms of being worth caring about. We then discuss how such outcomes could be avoided and argue that under certain conditions the only possible remedy would be a globally coordinated effort to control human evolution by adopting social policies that modify the default fitness function of future life forms. [In Death and Anti-Death, ed. Charles Tandy (Ria University Press, 2005)] [pdf | html]
Why I Want to be a Posthuman When I Grow Up new
After some definitions and conceptual clarification, I argue for two theses. First, some posthuman modes of being would be extremely worthwhile.

A History of Transhumanist Thought
The human desire to acquire new capacities, to extend life and overcome obstacles to happiness is as ancient as the species itself. But transhumanism has emerged gradually as a distinctive outlook, with no one person being responsible for its present shape. Here's one account of how it happened. [Journal of Evolution and Technology, 2005, Vol.14, No. 1] [pdf]

Existential Risks: Analyzing Human Extinction Scenarios and Related Hazards Existential risks are ways in which we could screw up badly and permanently. Remarkably, relatively little serious work has been done in this important area. The point, of course, is not to welter in doom and gloom but to better understand where the biggest dangers are so that we can develop strategies for reducing them.

[Futures, 2003, Vol. 35, No. 7, pp. 759 - 764, where it appears as the target paper of a symposium, together with five commentaries by other people, to which I had the opportunity to reply in the next issue.]
Where Are They? Why I hope the search for extraterrestrial life finds nothing new Discusses the Fermi paradox, and explains why I hope we find no signs of life, whether extinct or still active, on Mars or anywhere else we may look. [Technology Review, 2008, May/June issue, pp. 72-77.] [pdf]
simulationAre You Living in a Computer Simulation? This paper argues that at least one of the following propositions is true: (1) the human species is very likely to go extinct before reaching the posthuman stage; (2) any posthuman civilization is extremely unlikely to run significant number of simulations or (variations) of their evolutionary history; (3) we are almost certainly living in a computer simulation. It follows that the naïve transhumanist dogma that there is a significant chance that we will one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation. A number of other consequences of this result are also discussed.

PHILOSOPHY OF SCIENCE & PROBABILITY

anthropicAnthropic Bias: Observation Selection Effects in Science and Philosophy
Failure to consider observation selection effects result in a kind of bias that infest many branches of science and philosophy. This book presented the first mathematical theory for how to correct for these biases. It also discusses some implications for cosmology, evolutionary biology, game theory, the foundations of quantum mechanics, the Doomsday argument, the Sleeping Beauty problem, the search for extraterrestrial life, the question of whether God exists, and traffic planning. Five sample chapters are online along with a brief primer. [Routledge, New York, 2002]
Self-Locating Belief in Big Worlds: Cosmology's Missing Link to Observation
Current cosmological theories say that the world is so big that all possible observations are in fact made. But then, how can such theories be tested? What could count as negative evidence? To answer that, we need to consider observation selection effects. [Journal of Philosophy, 2002, Vol. 99, No. 12, pp. 607-623] [html | pdf]

A Primer on the Doomsday argument
The Doomsday argument purports to prove, from basic probability theory and a few seemingly innocuous empirical premises, that the risk that our species will go extinct soon is much greater than previously thought. My view is that the Doomsday argument is inconclusive - although not for any trivial reason. In my book, I argued that a theory of observation selection effects is needed to explain where it goes wrong.

PHILOSOPHY OF MIND

If two brains are in identical states, are there two numerically distinct phenomenal experiences or only one? Two, I argue. But what happens in intermediary cases? This paper looks in detail at this question and suggests that there can be a fractional (non-integer) number of qualitatively identical experiences. This has implications for what it is to implement a computation and for Chalmer's Fading Qualia thought experiment. [Minds and Machines, 2006, Vol. 16, No. 2, pp. 185-200] [pdf]

 

FAILED STAND-UP COMEDIAN

Prior to taking up my current post as Director of the Future of Humanity Institute at Oxford University, I was a British Academy Postdoctoral Research Fellow in the Faculty of Philosophy.  Before that, I was a lecturer at Yale University, in the Department of Philosophy and the Institute for Social and Policy Studies.

Beside philosophy, I also have a background in physics, computational neuroscience, mathematical logic, and artificial intelligence.  My performance as an undergraduate set a national record in Sweden.  I was a busy young man. Before becoming a tweedy academic, I also dabbled in painting and poetry, and for a while I did stand-up comedy in London.

I co-founded the World Transhumanist Association in 1998 to encourage public engagement with the prospect of future technologies being used to enhance human capacities. The WTA, a non-profit grassroots organization, now has some 5,000 members from all over the world, and local chapters in many countries.  In 2004, I co-founded the Institute for Ethics and Emerging Technologies, a virtual think tank on technology-policy topics.

In the early days, a common reaction was "this is just science fiction".  But in the last few years, academia (and to some extent the wider public) has been gradually ceasing to ignore what is arguably one of the most important issues of our time: how we might use our growing technological powers to improve human lives by changing not only the world around us but also ourselves (e.g. by developing and ensuring wide access to a set of options for prolonging healthy lifespan, augmenting cognition, and improving emotional well-being).  Discussions no longer get stuck on whether human enhancement will ever be possible.  Instead, the focus is increasingly on ethics: whether it ought to be done.  This is a bit of progress.

The enhancement debate frequently gets polarized into two opposing ideological camps, transhumanists vs. bioconservatives.  That is unfortunate.  Hopefully, a further few years hence, we will finally enter the more constructive phase where we ask not whether human enhancement is good in general, yes or no, but rather questions like:  Which enhancements, exactly?  How to solve the myriad technical problems?  What kind of regulation and public policy and funding priorities do we need?

THE BIG PICTURE

My real focus, however, is research.  Since 2006, I’ve been directing a unique multidisciplinary research institute at Oxford University, the (preposterously but descriptively named) Future of Humanity Institute; and I was made full professor in the Faculty of Philosophy in 2008.  The FHI is part of the Faculty of Philosophy and the James Martin 21st Century School.

As this page reveals, my research interests are multifarious.  The common denominator is that they are all parts of a quest to think more rationally about big picture questions for humanity.  This is theoretically fascinating.  But ultimately, I’m working on these issues because I believe that it is practically very important to get them right.  In the end, the goal is to help make the world better place.  And for me, I think the best way to contribute (at least at my present life stage) is by doing this kind of intellectual work.

Let’s try a little credo:  I see philosophy and science as overlapping parts of a continuum.  Many of the questions that I am interested in lie in the intersection.  I tend to think in terms of probability distributions rather than dichotomous epistemic categories.  I guess that in the far future the human condition will have changed profoundly (for better or worse).  I think there is a non-trivial chance that this "far" future will be reached in this century, within the lifespan of some currently existing people.  Regarding many big picture questions, I think there is a very real possibility that our views are very wrong.  Improving the ways in which we reason, act, and prioritize under uncertainty would have wide relevance to many of our biggest challenges.

I’m probably best known for my work in four areas (i) as an intellectual leader of the transhumanist movement, with many related writings in bioethics and on consequences of future technologies; (ii) as originator of the concept of existential risk; (iii) as originator of the simulation argument; and (iv) as developer of the first mathematically explicit theory of observation selection effects.  A fifth area of my work, which has attracted less attention but which I think of as also significant, is on the question of what a consequentialist should do (e.g. Astronomical Waste, Infinite Ethics, Technological Revolutions).

I am happy but frequently find myself wondering: Am I spending my energies in the right place?  Am I doing the most meaningful thing I could be doing?

ON THE BANK

On the bank at the end
Of what was there before us
Gazing over to the other side
On what we can become
Veiled in the mist of naïve speculation
We are busy here preparing
Rafts to carry us across
Before the light goes out leaving us
In the eternal night of could-have-been

PYTHAGOREAN JAMBOREE

The astral glockenspiel quivers
As our bodies align in the orbit of Venus;
Galloping stallions and mares
Print with their hooves, pixel by pixel,
The lights and shadows of mortal life,
Pink flesh for the gods’ insection ‒
Who clap their hands together at the sight;
For the heavens love the authentic peep.
Whence the orbs appear to us sublunars
Empty, mute, and dimly lit;
While on the other wide the jamboree,
Abuzz with primal harmony,
Fluoresces with the ecstasy of being.

(2007)

 

UNPRETTY POEM

See the plucked chicken
Its throat ineptly slit
Over the abattoir drain
Bleeding its life away

See the man running
Running for his life
Chased by a rabid dog
The pit-bull called Eternity

See the fountain gushing
From fifty fishes’ mouths
Various parabolas
Same filthy water

(2008)
