Only the bad artists of the nineteenth century were frightened by the invention of photography; the good ones all welcomed it and used it.

The recognized achievements of some Negroes, despite rigid racial barriers, indicate that society by its prejudices may be depriving itself of valuable contributions from many others. It is now doubtful whether America can afford the luxury of such a waste of human resources.

Children who are treated as if they are uneducable almost invariably become uneducable.

Evidently one cannot look for long at the Last Supper without ceasing to study it as a composition, and beginning to speak of it as a drama. It is the most literary of all great pictures, one of the few of which the effect may largely be conveyed - can even be enhanced - by description.

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.

Fine colour implies a unified relationship, in which each part is subordinate to the whole, and the transitions between them are felt to be as precious and beautiful as the colours themselves. In fact, the colours themselves must be continuously modified and broken as part of the transition.

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.
