The ups and downs of this cosmos may sometimes be acknowledged to be metaphorical ups and downs, but until about Newton's time most people took the "up" of heaven and the "down" of hell to be more or less descriptive.

It seems to me that Canadian sensibility has been profoundly disturbed, not so much by our famous problem of identity, important as that is, as by a series of paradoxes in what confronts that identity. It is less perplexed by the question "Who am I?" than by some such riddle as "Where is here?

In 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.

Poetry 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.

Myths, as compared with folk tales, are usually in a special category of seriousness: they are believed to have "really happened,"or to have some exceptional significance in explaining certain features of life, such as ritual. Again, whereas folk tales simply interchange motifs and develop variants, myths show an odd tendency to stick together and build up bigger structures. We have creation myths, fall and flood myths, metamorphose and dying-god myths.

Science 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.
