Science, like art, is not a copy of nature but a re-creation of her.

This is the concentration camp and crematorium at Auschwitz. This is where people were turned into numbers. Into this pond were flushed the ashes of some four million people. And that was not done by gas. It was done by arrogance. It was done by dogma. It was done by ignorance. When people believe that they have absolute knowledge, with no test in reality, this is how they behave.

Fifty years from now if an understanding of man's origins, his evolution, his history, his progress is not in the common place of the school books we shall not exist.

We are nature's unique experiment to make the rational intelligence prove itself sounder than the reflex. Knowledge is our destiny

The new theory, of course, always subsumes more effects than the old. But the remarkable thing is that when it is discovered, it also wholly changes our conception of how the world works.

We treat ourselves both as objects of language and as speakers of language, both as objects of the symbolism and as symbols in it. And all the difficult paradoxes which go right back to Greek times and reappear in modern mathematics depend essentially on this.

The most remarkable discovery ever made by scientists was science itself.

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.

Dissent is the native activity of the scientist, and it has got him into a good deal of trouble in the last years. But if that is cut off, what is left will not be a scientist. And I doubt whether it will be a man.
