it may be

These are the edgings and inchings of final form,
The swarming activities of the formulae
Of statement, directly and indirectly getting at,

Like an evening evoking the spectrum of violet,
A philosopher practicing scales on his piano,
A woman writing a note and tearing it up.

It is not in the premise that reality
Is a solid. It may be a shade that traverses
A dust, a force that traverses a shade.

-- Wallace Stevens, from "An Ordinary Evening in New Haven"
