One doesn't bother to believe the credible: the credible is believed already, by definition. There's no adventure of the mind.
Northrop FryeLiterature is a human apocalypse, man's revelation to man, and criticism is not a body of adjudications, but the awareness of that revelation, the last judgement of mankind.
Northrop FryeCharacters 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.
