The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.

The true delight is in the finding out rather than in the knowing.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!', but 'That's funny ...'

To introduce something altogether new would mean to begin all over, to become ignorant again, and to run the old, old risk of failing to learn.

Inspect every piece of pseudoscience and you will find a security blanket, a thumb to suck, a skirt to hold. What does the scientist have to offer in exchange? Uncertainty! Insecurity!

A subtle thought that is in error may yet give rise to fruitful inquiry that can establish truths of great value.

How often people speak of art and science as though they were two entirely different things, with no interconnection. An artist is emotional, they think, and uses only his intuition; he sees all at once and has no need of reason. A scientist is cold, they think, and uses only his reason; he argues carefully step by step, and needs no imagination. That is all wrong. The true artist is quite rational as well as imaginative and knows what he is doing; if he does not, his art suffers. The true scientist is quite imaginative as well as rational, and sometimes leaps to solutions where reason can follow only slowly; if he does not, his science suffers.

Whereas the man of action binds his life to reason and its concepts so that he will not be swept away and lost, the scientific investigator builds his hut right next to the tower of science so that he will be able to work on it and to find shelter for himself beneath those bulwarks which presently exist.

There is a single light of science, and to brighten it anywhere is to brighten it everywhere.

The facts, gentlemen, and nothing but the facts, for careful eyes are narrowly watching.
