Poetry is the name, in my dialect, of a constituent or property of being. Like shapeliness and grace, symmetry and love, it must be made as well as found, but it is made, it seems to me, by many creatures other than human beings, and found in countless contexts far from human language. I try not to use the word as the collective plural of poem, just as I refrain from using love as the plural of romance (or of copulation).
