The Cathedrals were built to the glory of God; New York was built to the glory of Mammon.

The difference between what we see and a sheet of white paper with a few thin lines on it is very great. Yet this abstraction is one which we seem to have adopted almost instinctively at an early stage in our development, not only in Neolithic graffiti but in early Egyptian drawings. And in spite of its abstract character, the outline is responsive to the least tremor of sensibility.

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 still try to learn from history. History is ourselves.

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.

People sometimes tell me that they prefer barbarism to civilisation. I doubt if they have given it a long enough trial. Like the people of Alexandria, they are bored by civilisation; but all the evidence suggests that the boredom of barbarism is infinitely greater.

We can hardly imagine a state of mind in which all material objects were regarded as symbols of spirtual truths or episodes in sacred history. Yet, unless we make this effort of imagination, Medieval art is largely incomprehensible.

Gargoyles were the complement to saints; Leonardo's caricatures were complementary to his untiring search for ideal beauty. And gargoyles were the expression of all the passions, the animal forces, the Caliban gruntings and groanings which are left in human nature when the divine has been poured away. Leonardo was less concerned than his Gothic predecessors with the ethereal parts of our nature, and so his caricatures, in their expression of passionate energy, merge imperceptibly into the heroic.
