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.

The nude gains its enduring value from the fact that it reconciles several contrary states. It takes the most sensual and immediately interesting object, the human body, and puts it out of reach of time and desire; it takes the most purely rational concept of which mankind is capable, mathematical order, and makes it a delight to the senses; and it takes the vague fears of the unknown and sweetens them by showing that the gods are like men and may be worshiped for their life-giving beauty rather than their death-dealing powers.

The history of art cannot be properly understood without some reference to the history of science. In both we are studying the symbols by which man affirms his mental scheme, and these symbols, be they pictorial or mathematical, a fable or formula, will reflect the same changes.

The nude does not simply represent the body, but relates it, by analogy, to all structures that have become part of our imaginative experience.

This became Delacroix 's theme: that the achievements of the spirit all that a great library contained were the result of a state of society so delicately balanced that at the least touch they would be crushed beneath an avalanche of pent-up animal forces.

I believe order is better than chaos, creation better than destruction. I prefer gentleness to violence, forgiveness to vendetta. On the whole I think that knowledge is preferable to ignorance, and I am sure that human sympathy is more valuable than ideology. I believe that in spite of the recent triumphs of science, men haven't changed much in the last two thousand years; and in consequence we must try to learn from history.
