"There is no doubt that Goya thought that one of the drugs chiefly responsible for the sleep of reason was the Church, and he had the lowest possible opinion of ecclesiastical institutions. However, this did not prevent him from painting religious pictures, completely sincerely because, like all Latin people, however little he believed in Christianity, he felt himself to be within the structure of the Catholic Church. One of his finest works was the decoration of a church near Madrid called S. Antonio de la Florida. He used the kind of device that would have appealed to Tiepolo. He painted a balcony round the drum of a cupola, and behind it he put a crowd of loiterers who are supposed to be watching the saint raise a man from the dead. Very few of them are interested in this unusual event. They are interested in each other or themselves, and show very well the curious tension between the individual and the collective, which is the essence of a crowd."

“Two pictures painted in the year 1907 can conveniently be taken as the starting point of twentieth-century art. They are Matisse's Blue Nude and Picasso's Demoiselles d'Avignon; and both these cardinal, revolutionary pictures represent the nude. The reason is that the revolt of twentieth-century painters was not against academicism: that had been achieved by the impressionists. It was a revolt against the doctrine, with which the impressionists implicitly agreed, that the painter should be no more than a sensitive and well-informed camera. And the very elements of symbolism and abstraction that made the nude an unsuitable subject for the impressionists commended it to their successors. When art was once more concerned with concepts rather than sensations, the nude was the first concept that came to mind.”

“What on earth has given opera its prestige in western civilisation — a prestige that has outlasted so many different fashions and ways of thought? Why are people prepared to sit silently for three hours listening to a performance of which they do not understand a word and of which they very seldom know the plot? Why do quite small towns all over Germany and Italy still devote a large portion of their budgets to this irrational entertainment? Partly, of course, because it is a display of skill, like a football match. But chiefly, I think, because it is irrational. "What is too silly to be said may be sung" — well, yes; but what is too subtle to be said, or too deeply felt, or too revealing or too mysterious — these things can also be sung and can only be sung.”

“To anyone who is not an artist it must seem rather strange that Degas who could do anything — for whom setting down what he saw presented no difficulties at all — should have continued to draw the same poses year after year — often, it would seem, with increasing difficulty. Just as a classical dancer repeats the same movements again and again, in order to achieve a greater perfection of line and balance, so Degas repeats the same motifs, it was one of the things that gave him so much sympathy with dancers. He was continually struggling to achieve an idea of perfect form, but this did not prevent him looking for the truth in what might seem an artificial situation.”

“Sweeping, confident articles on the future seem to me, intellectually, the most disreputable of all forms of public utterance.”

“I wonder if a single thought that has helped forward the human spirit has ever been conceived or written down in an enormous room.”

“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. Ruskin said in his Elements of Drawing, "Give me some mud off a city crossing, some ochre out of a gravel-pit, a little whitening, and some coal dust, and I will paint you a luminous picture, if you give me time to gradate my mud, and subdue my dust." In many works by the greatest colourists — Rembrandt and Watteau are examples — there are very few identifiable colours.”
