One, who is not, we see; but one, whom we see not, is;
Surely, this is not that; but that is assuredly this.

What, and wherefore, and whence: for under is over and under;
If thunder could be without lightning, lightning could be without
thunder.

Doubt is faith in the main; but faith, on the whole, is doubt;
We cannot believe by proof; but could we believe without?

Why, and whither, and how? for barley and rye are not clover;
Neither are straight lines curves; yet over is under and over.

One and two are not one; but one and nothing is two;
Truth can hardly be false, if falsehood cannot be true.

Parallels all things are; yet many of these are askew;
You are certainly I; but certainly I am not you.

One, whom we see not, is; and one, who is not, we see;
Fiddle, we know, is diddle; and diddle, we take it, is dee.

A.C. Swinburne.
