Since science's competence extends to observable and measurable phenomena, not to the inner being of things, and to the means, not to the ends of human life, it would be nonsense to expect that the progress of science will provide men with a new type of metaphysics, ethics, or religion.
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 MaritainArt 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.
