Plato: The Republic

4. BOOK IV (continued)

No more than you can say that the hands of the archer push and pull the bow at the same time, but what you say is that one hand pushes and the other pulls.

Exactly so, he replied.

And might a man be thirsty, and yet unwilling to drink?

Yes, he said, it constantly happens.

And in such a case what is one to say? Would you not say that there was something in the soul bidding a man to drink, and something else forbidding him, which is other and stronger than the principle which bids him?

I should say so.

And the forbidding principle is derived from reason, and that which bids and attracts proceeds from passion and disease?

Clearly.

Then we may fairly assume that they are two, and that they differ from one another; the one with which man reasons, we may call the rational principle of the soul, the other, with which he loves and hungers and thirsts and feels the flutterings of any other desire, may be termed the irrational or appetitive, the ally of sundry pleasures and satisfactions?

Yes, he said, we may fairly assume them to be different.

Then let us finally determine that there are two principles existing in the soul. And what of passion, or spirit? Is it a third, or akin to one of the preceding?

I should be inclined to say--akin to desire.

Well, I said, there is a story which I remember to have heard, and in which I put faith. The story is, that Leontius, the son of Aglaion, coming up one day from the Piraeus, under the north wall on the outside, observed some dead bodies lying on the ground at the place of execution. He felt a desire to see them, and also a dread and abhorrence of them; for a time he struggled and covered his eyes, but at length the desire got the better of him; and forcing them open, he ran up to the dead bodies, saying, Look, ye wretches, take your fill of the fair sight.
