Plato: The Republic

6. BOOK VI (continued)

Of course, he replied; but I wish that you would tell me whether you conceive this supreme principle of the good to be knowledge or pleasure, or different from either.

Aye, I said, I knew all along that a fastidious gentleman like you would not be contented with the thoughts of other people about these matters.

True, Socrates; but I must say that one who like you has passed a lifetime in the study of philosophy should not be always repeating the opinions of others, and never telling his own.

Well, but has any one a right to say positively what he does not know?

Not, he said, with the assurance of positive certainty; he has no right to do that: but he may say what he thinks, as a matter of opinion.

And do you not know, I said, that all mere opinions are bad, and the best of them blind? You would not deny that those who have any true notion without intelligence are only like blind men who feel their way along the road?

Very true.

And do you wish to behold what is blind and crooked and base, when others will tell you of brightness and beauty?

GLAUCON - SOCRATES

Still, I must implore you, Socrates, said Glaucon, not to turn away just as you are reaching the goal; if you will only give such an explanation of the good as you have already given of justice and temperance and the other virtues, we shall be satisfied.

Yes, my friend, and I shall be at least equally satisfied, but I cannot help fearing that I shall fall, and that my indiscreet zeal will bring ridicule upon me. No, sweet sirs, let us not at present ask what is the actual nature of the good, for to reach what is now in my thoughts would be an effort too great for me. But of the child of the good who is likest him, I would fain speak, if I could be sure that you wished to hear--otherwise, not.
