Art and poetry cannot do without one another. Yet the two words are far from being synonymous. By Art I mean the creative or producing, work-making activity of the human mind. By Poetry I mean, not the particular art which consists in writing verses, but a process both more general and more primary: that intercommunication between the inner being of things and the inner being of the human Self which is a kind of divination (as was realized in ancient times; the Latin vates was both a poet and a diviner). Poetry, in this sense, is the secret life of each and all of the arts.
Jacques MaritainIt is necessary that the object that the artist is shaping, whether it be a vase of clay or a fishing boat, be significant of something other than itself. This object must be a sign as well as an object; a meaning must animate it, and make it say more than it is.
Jacques MaritainEvery work of art reaches man in his inner powers. It reaches him more profoundly and insidiously than any rational proposition, either cogent demonstration or sophistry. For it strikes him with two terrible weapons, Intuition and Beauty, and at the single root in him of all his energies... Art and Poetry awaken the dreams of man, and his longings, and reveal to him some of the abysses he has in himself.
