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 MaritainPoetic experience is distinct in nature from mystical experience. Because poetry emanates from the free creativity of the spirit,it is from the very start oriented toward expression, and terminates in a word proffered, it wants to speak; whereas mystical because it emanates from the deepest longing of the spirit bent on knowing, tends of itself toward silence and internal fruition. Poetic experience is busy with the created world and the enigmatic and innumerable relations of existents with one another, not with the Principle of Being.
