"Today we know that on the sub-atomic level the fate of an electron or a whole atom is not determined by its past. But this discovery has not led to any basically new departure in the philosophy of nature, only to a state of bewildered embarrassment, a further retreat of physics into a language of even more abstract symbolism. Yet if causality has broken down and events are not rigidly governed by the pushes and pressures of the past, may they not be influenced in some manner by the "pull" of the future—which is a manner of saying that "purpose" may be a concrete physical factor in the evolution of the universe, both on the organic and unorganic levels. In the relativistic cosmos, gravitation is a result of the curvature and creases in space which continually tend to straighten themselves out—which, as Whittaker remarked, "is a statement so completely teleological that it certainly would have delighted the hearts of the schoolmen."

“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.”

“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.”

“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.”
