The progress of science, like an ancient desert trail, is strewn with the bleached skeletons of discarded theories, doctrines, and axioms which seemed to possess eternal life.

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.

As modern physics started with the Newtonian revolution, so modern philosophy starts with what one might call the Cartesian Catastrophe. The catastrophe consisted in the splitting up of the world into the realms of matter and mind, and the identification of 'mind' with conscious thinking. The result of this identification was the shallow rationalism of l' esprit Cartesien, and an impoverishment of psychology which it took three centuries to remedy even in part.

The most persistent sound which reverberates through man's history is the beating of war drums.

Nobody before the Pythagorean had thought that mathematical relations held the secret of the universe. Twenty-five centuries later, Europe is still blessed and cursed with their heritage. To non-European civilizations, the idea that numbers are the key to both wisdom and power, seems never to have occurred.

When a person identifies himself with a group his critical faculties are diminished and his passions enhanced by a kind of emotive resonance. The individual is not a killer, the group is, and by identifying with it, the individual becomes one. This is the infernal dialect reflected in man's history.

...the cosmology of a given age is not the result of unilinear, "scientific" development, but rather the most striking, imaginative symbol of its mentality- the projection of its conflicts, prejudice and specific ways of double-think onto the graceful sky.
