Philosophers are people who know less and less about more and more, until they know nothing about everything. Scientists are people who know more and more about less and less, until they know everything about nothing.

I have found the missing link between the higher ape and civilized man; it is we.

I see the creative accomplishments of which highly gifted humans are capable as special cases of the universal creative process, that game played by everyone against everyone else, from which wells up all that has never been before.

In nature we find not only that which is expedient, but also everything which is not so inexpedient as to endanger the existence of the species.

Scientific truth is universal, because it is only discovered by the human brain and not made by it, as art is.

All scientific knowledge to which man owes his role as master of the world arose from playful activities.

The rushed existence into which industrialized, commercialized man has precipitated himself is actually a good example of an inexpedient development caused entirely by competition between members of the same species. Human beings of today are attacked by so-called manager diseases, high blood pressure, renal atrophy, gastric ulcers, and torturing neuroses: they succumb to barbarism because they have no more time for cultural interests.
