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

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.

When Coleridge tried to define beauty, he returned always to one deep thought; beauty, he said, is unity in variety! Science is nothing else than the search to discover unity in the wild variety of nature,-or, more exactly, in the variety of our experience. Poetry, painting, the arts are the same search, in Coleridge's phrase, for unity in variety.

Whether our work is art or science or the daily work of society, it is only the form in which we explore our experience which is different.

We gain our ends only with the laws of nature; we control her only by understanding her laws.

To me the most interesting thing about man is that he is an animal who practices art and science and in every known society practices both together.

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.
