There is a curious law of art... that even the attempt to reproduce the act of seeing, when carried out with sufficient energy, tends to lose its realism and take on the unnatural glittering intensity of hallucination.
Northrop FryeScience begins with the world we have to live in, accepting its data and trying to explain its laws. From there, it moves toward the imagination: it becomes a mental construct, a model of a possible way of interpreting experience. The further it goes in this direction, the more it tends to speak the language of mathematics, which is really one of the languages of the imagination, along with literature and music. Art, on the other hand, begins with the world we construct, not with the world we see. It starts with the imagination, and then works toward ordinary experience.
Northrop FryePoetry is the most direct and simple means of expressing oneself in words: the most primitive nations have poetry, but only quitewell developed civilizations can produce good prose. So don't think of poetry as a perverse and unnatural way of distorting ordinary prose statements: prose is a much less natural way of speaking than poetry is. If you listen to small children, and to the amount of chanting and singsong in their speech, you'll see what I mean.
Northrop FryeIn literature, questions of fact or truth are subordinated to the primary literary aims of producing a structure of words for its own sake, and the sign-values of symbols are subordinated to their importance as a structure of interconnected motifs.
