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.

Leonardo is the Hamlet of art history whom each of us must recreate for himself.

I just don't think the moon is going to be an adequate substitute for the fact that we haven't addressed ourselves to clearing up the slums.

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.

Antique art has come down to us in a fragmentary condition, and we have virtuously adapted our taste to this necessity. Almost all our favorite specimens of Greek sculpture, from the sixth century onward, were originally parts of compositions, and if we were faced with the complete group in which the Charioteer of Delphi was once a subsidiary figure, we might well experience a moment of revulsion. We have come to think of the fragment as more vivid, more concentrated, and more authentic.

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.

The dark ghettos are social, political, educational and-above all-economic colonies. Their inhabitants are subject peoples, victims of the greed, cruelty, insensitivity, guilt, and fear of their masters.
