I profoundly admire Aldous Huxley, both for his philosophy and uncompromising sincerity. But I disagree with his advocacy of 'the chemical opening of doors into the Other World', and with his belief that drugs can procure 'what Catholic theologians call a gratuitous grace'. Chemically induced hallucinations, delusions and raptures may be frightening or wonderfully gratifying; in either case they are in the nature of confidence tricks played on one's own nervous system.
Arthur KoestlerThe disastrous history of our species indicates the futility of all attempts at a diagnosis which do not take into account the possibility that homo sapiens is a victim of one of evolution's countless mistakes.
