"Once grant the ethics of vivisectionists and you not only sanction the experiment on the human subject, but make it the first duty of the vivisector. If a guinea pig may be sacrificed for the very little that may be learned from it, shall not a man be sacrificed for the great deal that can be learned from him." George Bernard Shaw
