363+;;Quote: suppose there were 60 billion chemical elements uniformly distributed; there would be no science and perhaps no thought and life; every pebble would be new

363+;;Quote: if all facts were complex, they would not repeat; a chance occurrence of a thousand circumstances

373 ;;Quote: neither calculations nor machines can replace the mathematician. They can find order but not unexpected order

373+;;Quote: the soul of a fact is its unexpected order

389 ;;Quote: mathematical invention often occurs after a long period of unconscious work following and followed by conscious work

413 ;;Quote: whoever speaks of absolute space uses a meaningless phrase; space is relative to other objects, e.g., place du Pantheon

414 ;;Quote: the distance between two points is meaningless by itself; it depends on how distance is measured

415 ;;Quote: we can measure distance with light only if we suppose that the velocity of light is constant for all observers

415+;;Quote: Lorentz explained the Michelson experiments by supposing the velocity of light was constant while lengths depended on direction

417 ;;Quote: space is in reality amorphous and the things which are therein alone give it a form

454 ;;Quote: mathematics is independent of the existence of material objects; mathematical existence means free from contradiction

483 ;;Quote: a demonstration in analytic logic leads to an immense tautology. Logic is sterile unless made fruitful by intuition

484 ;;Quote: the antinomies of formal logic arise because classifications must be modified for unforeseen objects
