“If one tries to understand the position of art today, one must also try to understand the conditions that have created the development of our perception of art and our perception of the relation to the individual and to society. The artist takes an active part in the campaign to deepen this our knowledge of the basis of our existence, the basis which, for him, makes possible an artistic creation. The artist's interest cannot be restricted to a single field; he must seek the highest perception of everything, of the whole and its details. Nothing can be sacred to him, because everything has become important to him.”

Context: If art is to nourish the roots of our culture, society must set the artist free to follow his vision wherever it takes him. We must never forget that art is not a form of propaganda; it is a form of truth.
Context: If art is to nourish the roots of our culture, society must set the artist free to follow his vision wherever it takes him. We must never forget that art is not a form of propaganda; it is a form of truth. And as Mr. MacLeish once remarked of poets, there is nothing worse for our trade than to be in style. In free society art is not a weapon and it does not belong to the spheres of polemic and ideology. Artists are not engineers of the soul. It may be different elsewhere. But democratic society — in it, the highest duty of the writer, the composer, the artist is to remain true to himself and to let the chips fall where they may. In serving his vision of the truth, the artist best serves his nation. And the nation which disdains the mission of art invites the fate of Robert Frost's hired man, the fate of having "nothing to look backward to with pride, and nothing to look forward to with hope."

Context: I outline in simple terms... our current understanding of the cognitive psychological and neurobiological basis of perception, memory, emotion, empathy, and creativity.... the principles of the viewer's response to art are applicable to all periods of painting.

Context: The artist must learn the difference between the appearance of an object and the interpretation of this object through his medium. The artist must create a spark before he can make a fire and before art is born, the artist must be ready to be consumed by the fire of his own creation.
