Around us, out of a simple primal form,
Impossible; yet you know that every man
Before his birth, a few brief years ago,
Was once no more than a single living cell.
You think it ends your theory of creation.
You say that God made you; and yet you know
—And reconcile your creed with what you know—
That you yourself originally”—he held up
A gleaming pencil-case—“were a little piece
Of matter, not so large as the end of this.
