Once upon a time is what the fence dividing up a mountain
range announces, in lines at once irregular and even.

For drama it depends upon a clear beginning, middle, and
end. Its effects? Cathartic, purging landowners of their terror,
interlopers of their pity. On guard! the playwright cries. All
the world’s a fence, the groundlings say.

In the ancient quarrel between fancy and the imagination the
fence takes both sides. Nor does it distinguish between form
and content, poetry and prose.

These are the four directions of the fence: up, down, right,
wrong, black, white, male, female. Nevertheless, at night the
fence points only toward the future, time’s true north.

In Tennessee someone is pouring the wilderness into a jar—
that’s one way to build a fence. Here’s another: trace a pebble’s
lineage back to Creation.
