In addition to these, counting.

I can count now.

How do you do it?

One, two, three, four.

Look, now; what you deem four is really ten, and a perfect triangle, and what we swear by.

And after that, stranger, you will have knowledge concerning earth and air and water and fire-the mass of each, and what form it has, and what motion by consequence.

You mean this: that I shall be immortal, changing into one form after another? But that is enough on this subject.
