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.
