“The work of art has its origin in an unconscious impulse that springs from collective substrata of universal values common to all men, from which all men draw their gestures, and from which the artist derives the 'archaic' of organic existence. Every man of his own accord extracts the human element from this base, without realizing it, and in an elementary and immediate way.”

Italian Report (1955)
Context: A more rewarding approach to painting, in my opinion the only valid one, is to regard it as a deeply personal and private activity and to remember that even when the painter works directly for the public — when there is sufficient common ground to allow him to do so — the real merit of the work will depend on the personal vision of the artist and the work will only be truly understood if it is approached by each in the same spirit as the painter painted it. We must be willing to assume the same sort of responsibility and share the dilemma out of which the work was created in order to be able to feel with the artist. Since the deepest and truest dilemma, from which all good art springs, is the human condition we have every right to regard the needs of our own consciousness as the final court in judging the merit of a work of art, we have in fact a moral obligation to do so. This demands the precise honesty from the spectator as was required from the artist in making the painting. It is their common ground, the area within which communication can occur. Art in the end speaks to the secret soul of the individual and of the most secret sorrows. For this reason it is true that the development that produces great art is a moral and not an aesthetic development..

Some Notes on Caravaggio (1956)

Peace and the Public Mind (1935)
Context: The force which makes for war does not derive its strength from the interested motives of evil men; it derives its strength from the disinterested motives of good men. Pacifists have sometimes evaded that truth as making too great a concession to Mars, as seeming to imply (which it does not in fact) that in order to abolish war, men must cease to be noble.
Base motives are, of course, among those which make up the forces that produce war. Base motives are among those which get great cathedrals built and hospitals constructed-contractors' profit-seeking, the vested interests of doctors and clergy. But Europe has not been covered by cathedrals because contractors wanted to make money, or priests wanted jobs.

Context: What I am searching for... is some formula that would combine individual initiative with universal values, and that combination would give us a truly organic form. Form, which we discover in nature by analysis, is obstinately mathematical in its manifestations—which is to say that creation in art requires thought and deliberation. But this is not to say that form can be reduced to a formula. In every work of art it must be re-created, but that too is true of every work of nature. Art differs from nature not in its organic form, but in its human origins: in the fact that it is not God or a machine that makes a work of art, but an individual with his instincts and intuitions, with his sensibility and his mind, searching relentlessly for the perfection that is neither in mind nor in nature, but in the unknown. I do not mean this in an other-worldly sense, only that the form of the flower is unknown to the seed.

Context: The inevitable hypocrisy, which is associated with the all the collective activities of the human race, springs chiefly from this source: that individuals have a moral code which makes the actions of collective man an outrage to their conscience. They therefore invent romantic and moral interpretations of the real facts, preferring to obscure rather than reveal the true character of their collective behavior. Sometimes they are as anxious to offer moral justifications for the brutalities from which they suffer as for those which they commit. The fact that the hypocrisy of man's group behavior... expresses itself not only in terms of self-justification but in terms of moral justification of human behavior in general, symbolizes one of the tragedies of the human spirit: its inability to conform its collective life to its individual ideals. As individuals, men believe they ought to love and serve each other and establish justice between each other. As racial, economic and national groups they take for themselves, whatever their power can command.
