That is why I think, in defiance of Plato, that there is at once error and vulgarity in saying that poetry is a lie, except in the sense that Cocteau wrote one day: I am a lie who always tells the truth. The only poetry which lies purely and simply is academic, pseudo-classical, conceptually repetitive poetry, and it is not poetry.
Jacques MaritainPoetry proceeds from the totality of man, sense, imagination, intellect, love, desire, instinct, blood and spirit together.
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.
Jacques MaritainSince 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.
