"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."

“Without the hard little bits of marble which are called 'facts' or 'data' one cannot compose a mosaic; what matters, however, are not so much the individual bits, but the successive patterns into which you arrange them, then break them up and rearrange them.”

“God seems to have left the receiver off the hook, and time is running out.”

“The evolution of the brain not only overshot the needs of prehistoric man, it is the only example of evolution providing a species with an organ which it does not know how to use.”

“The sixth pre-Christian century—the miraculous century of Buddha, Confucius and Lâo-Tse, of the Ionian philosophers and Pythagoras—was a turning point for the human species. A March breeze seemed to blow across the planet from China to Samos, stirring man into awareness, like the breath of Adam's nostrils. In the Ionian school of philosophy, rational thought was emerging from the mythological dream-world. ...which, within the next two thousand years, would transform the species more radically than the previous two hundred thousand had done.”

“Men cannot be treated as units in operations of political arithmetic because they behave like the symbols for zero and the infinite, which dislocate all mathematical operations.”

“Einstein's space is no closer to reality than Van Gogh's sky. The glory of science is not in a truth more absolute than the truth of Bach or Tolstoy, but in the act of creation itself. The scientist's discoveries impose his own order on chaos, as the composer or painter imposes his; an order that always refers to limited aspects of reality, and is based on the observer's frame of reference, which differs from period to period as a Rembrant nude differs from a nude by Manet.”
