It is a very grave mistake to think that the enjoyment of seeing and searching can be promoted by means of coercion and a sense of duty. To the contrary, I believe it would be possible to rob even a healthy beast of prey of its voraciousness, if it were possible, with the aid of a whip, to force the beast to devour continuously, even when not hungry.

Logic will get you from A to B. Imagination will take you everywhere.

Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined for the insect, as well as for the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper.

God does not play dice.

The human mind has first to construct forms, independently, before we can find them in things.

Have the courage to take your own thoughts seriously, for they will shape you.

Out of complexity, find simplicity!
