FIRST PHILOSOPHER.
Cogito, ergo sum. I have thought, and therefore existence!
If the first be but true, then is the second one sure.

PUPIL.
As I think, I exist. 'Tis good! But who always is thinking?
Oft I've existed e'en when I have been thinking of naught.

SECOND PHILOSOPHER.
Since there are things that exist, a thing of all things there must
needs be;
In the thing of all things dabble we, just as we are.

THIRD PHILOSOPHER.
Just the reverse, say I. Besides myself there is nothing;
Everything else that there is is but a bubble to me.

FOURTH PHILOSOPHER.
Two kinds of things I allow to exist,—the world and the spirit;
Naught of others I know; even these signify one.

FIFTH PHILOSOPHER.
I know naught of the thing, and know still less of the spirit;
Both but appear unto me; yet no appearance they are.

SIXTH PHILOSOPHER.
I am I, and settle myself,—and if I then settle
Nothing to be, well and good—there's a nonentity formed.

SEVENTH PHILOSOPHER.
There is conception at least! A thing conceived there is, therefore;
And a conceiver as well,—which, with conception, make three.

PUPIL.
All this nonsense, good sirs, won't answer my purpose a tittle:
I a real principle need,—one by which something is fixed.

EIGHTH PHILOSOPHER.
Nothing is now to be found in the theoretical province;
Practical principles hold, such as: thou canst, for thou shouldst.
