Plato: The Republic

9. BOOK IX (continued)

On the other hand, every one sees that the principle of knowledge is wholly directed to the truth, and cares less than either of the others for gain or fame.

Far less.

`Lover of wisdom,' `lover of knowledge,' are titles which we may fitly apply to that part of the soul?

Certainly.

One principle prevails in the souls of one class of men, another in others, as may happen?

Yes.

Then we may begin by assuming that there are three classes of men-- lovers of wisdom, lovers of honour, lovers of gain?

Exactly.

And there are three kinds of pleasure, which are their several objects?

Very true.

Now, if you examine the three classes of men, and ask of them in turn which of their lives is pleasantest, each will be found praising his own and depreciating that of others: the money-maker will contrast the vanity of honour or of learning if they bring no money with the solid advantages of gold and silver?

True, he said.

And the lover of honour--what will be his opinion? Will he not think that the pleasure of riches is vulgar, while the pleasure of learning, if it brings no distinction, is all smoke and nonsense to him?

Very true.

And are we to suppose, I said, that the philosopher sets any value on other pleasures in comparison with the pleasure of knowing the truth, and in that pursuit abiding, ever learning, not so far indeed from the heaven of pleasure? Does he not call the other pleasures necessary, under the idea that if there were no necessity for them, he would rather not have them?

There can be no doubt of that, he replied.
