"Rousseau’s ideas were in the air; he only expressed what many of his contemporaries knew, namely that they were faced with a choice and had to decide either for Voltairianism, with its reasonableness and respectability, or for the surrender of historical traditions and a completely new beginning. There is no personal relationship in the whole history of European culture with more profound symbolic significance than that between Voltaire and Rousseau."

“The new Christian ideal of life did not at first alter the outward forms of art, but did alter its social function.”

“It would never have been possible for Byzantine court art to become the Christian art par excellence, if the Church itself had not become an absolute authority and had not felt itself to be mistress of the world. In other words, the Byzantine style was only able to gain a footing everywhere where there was a Christian art, because the Catholic Church in the West desired to become the power the Emperor was already in Byzantium.”

“The mania for self-observation and self-admiration in literature and the view that a work is the more true and the more convincing, the more directly the author reveals himself in it, are part of the intellectual inheritance of Rousseau. In the next hundred to hundred and fifty years everything of importance in European literature is stamped with this subjectivism. Not only Werther, René, Obermann, Adolphe, Jacopo Ortis, are among the successors of Saint-Preux, but also the heroes in later novels— from Balzac’s Lucien de Rubempré, Stendhal’s Julien Sorel, Flaubert’s Frédéric Moreau and Emma Bovary to Tolstoy’s Pierre, Proust’s Marcel and Thomas Mann’s Hans Castorp—are derived from it. They all suffer from the discrepancy between dream and reality and are the victim of the conflict between their illusions and practical, commonplace, middle-class life.”

“In spite of the growing differences of income, the ever-increasing concentration of capital and the steady increase of the proletariat, in a word, in spite of the growing opposition between classes, there is everywhere a certain social levelling that, at last, puts a definite end to the privileges of birth. This is the last stage of the trend towards the abolition of social distinctions which had been going on since the days of hereditary monarchy and authoritarian priesthood. The decisive step was due to the Sophists, who invented the completely new rationalistic conception of areté,independent of birth and breeding, to which every Greek without exception could attain. The next step in this levelling is taken by the Stoics, who first enunciated standards of human value that are free from all tinge of race and nationality. The Stoics’ freedom from national prejudice merely expressed a state of affairs already achieved in the kingdoms of Alexander’s successors, just as the liberalism of the Sophists is merely a reflection of the social conditions due to the rise of the commercial and industrial bourgeoisie of the cities.”

“If the resistances in one direction are impossible to overcome, then the artist’s invention and powers of expression turn to a goal the way to which is not obstructed, and it is very unusual for him even to be aware of the fact that his achievement is a substitute for the real thing. Even in the most liberal democracy the artist does not move with perfect freedom and unrestraint; even there he is restricted by innumerable considerations foreign to his art. The different measure of freedom may be of the greatest importance for him personally but in principle there is no difference between the dictates of a despot and the conventions of even the most liberal social order. If force in itself were contrary to the spirit of art, perfect works of art could arise only in a state of complete anarchy. But in reality the presuppositions on which the aesthetic quality of a work depends lie beyond the alternative presented by political freedom and compulsion.”

“The historical importance of the Carracci is extraordinary; the history of the whole of modern ‘church art’ begins with them.”
