No nude, however abstract, should fail to arouse in the spectator some vestige of erotic feeling... The desire to grasp and be united with another human is so fundamental a part of our nature that our judgement of what is known as 'pure form' is inevitably influenced by it, and one of the difficulties of the nude as a subject for art is that these instincts cannot be hidden.

One musn't overrate the culture of what used to be called "top people" before the wars. They had charming manners, but they were as ignorant as swans.

To hurry through the rise and fall of a fine, full sentence is like defying the role of time in human life.

Only the bad artists of the nineteenth century were frightened by the invention of photography; the good ones all welcomed it and used it. Degas liked it not only because it provided an accurate record, but because the snapshot showed him a means of escape from the classical rules of design. Through it he learnt to make a composition without the use of formal symmetry.

Our universe cannot even be stated symbolically. And this touches us all more directly than one might suppose. For example, artists, who have been very little influenced by social systems, have always responded instinctively to latent assumptions about the shape of the universe. The incomprehensibility of our new cosmos seems to me, ultimately, to be the reason for the chaos of modern art.

It is often said that Leonardo drew so well because he knew about things; it is truer to say that he knew about things because he drew so well.

Great works of art can be produced in barbarous societies - in fact the very narrowness of primitive society gives their ornamental art a peculiar concentration and vitality. At some time in the ninth century one could have looked down the Seine and seen the prow of a Viking ship coming up the river. Looked at today in the British Museum, it is a powerful work of art; but to the mother of a family trying to settle down in her little hut, it would have seemed less agreeable - as menacing to her civilisation as the periscope of a nuclear submarine.
