It is vain to say human beings ought to be satisfied with tranquillity: they must have action; and they will make it if they cannot find it.

Knowledge is an unending adventure at the edge of uncertainty.

Science has nothing to be ashamed of even in the ruins of Nagasaki. The shame is theirs who appeal to other values than the human imaginative values which science has evolved.

That is the essence of science: ask an impertinent question, and you are on the way to a pertinent answer.

We are all afraid for our confidence, for the future, for the world. That is the nature of the human imagination. Yet every man, every civilization, has gone forward because of its engagement with what it has set itself to do.

The symbol and the metaphor are as necessary to science as to poetry.

Man is unique not because he does science, and he is unique not because he does art, but because science and art equally are expressions of his marvelous plasticity of mind.

The most remarkable discovery ever made by scientists is science itself. The discovery must be compared in importance with the invention of cave-painting and of writing.

Science is the acceptance of what works and the rejection of what does not. That needs more courage than we might think.

It is a mistake to think of creative activity as something unusual.
