One Less X

How Boole put it. Take a class,
A set out of the world,
And call it x. Then the class

Of all non-x, all the rest
Of the world, is one, less x.
Let x stand for poems, the world

Of non-poems, which is not poems,
Is all one, less x. We float
In this spill of waves called poems

And say, all the world is one
Less all of us. While plus us,
The world is one, but non’s gone.
