Work, as we usually think of it, is energy expended for a further end in view; play is energy expended for its own sake, as with children's play, or as manifestation of the end or goal of work, as in "playing" chess or the piano. Play in this sense, then, is the fulfillment of work, the exhibition of what the work has been done for.
Northrop FryeThe poet, however, uses these two crude, primitive, archaic forms of thought (simile and metaphor) in the most uninhibited way, because his job is not to describe nature, but to show you a world completely absorbed and possessed by the human mind.
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.
