'It has been one of the most destructive modern prejudices that art and science are different and somehow incompatible interests. We have fallen into the habit of opposing the artistic to the scientific temper; we even identify them with a creative and a critical approach. In a society like ours which practices the division of labour there are of course specialized functions, as matters of convenience. As a convenience, and only as a convenience, the scientific function is different from the artistic. In the same way, the function of thought differs from, and complements, the function of feeling. But the human race is not divided into thinkers and feelers, and would not long survive the division.'
'Einstein rounded three centuries of the questioning of nature when he equated energy and mass in a single line:
This is not the same as the unification of concepts as that for which Keats was searching when he closed the Ode on a Grecian Urn with the lines
Beauty is truth, truth beauty, - that is all Ye know on earth, and all ye need to know.
But the likeness is more important than the difference. The likeness is more helpful in making us understand that the concepts of science are like the concepts of value, monuments to our sense of unity in nature.'
