Characters tend to be either for or against the quest. If they assist it, they are idealized as simply gallant or pure; if they obstruct it, they are characterized as simply villainous or cowardly. Hence every typical character...tends to have his moral opposite confronting him, like black and white pieces in a chess game.
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.
Northrop FryeA person who knows nothing about literature may be an ignoramus, but many people don't mind being that.
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.
