BOOK II. XI. 16-25
terminable and undiscoverable.—Therefore, there is some standard.—Then why do we not look for it and find it, and when we have found it thenceforth use it unswervingly, not so much as stretching out our finger without it? For this is something, I think, the discovery of which frees from madness those who use only opinion as the measure of all things, so that thenceforward, starting with certain principles that are known and clearly discriminated, we may use in the judgement of specific cases an organically articulated system of preconceived ideas.
What subject has arisen that we wish to investigate?—Pleasure.20—Subject it to the standard, put it into the balance. Should the good be the sort of thing that we can properly have confidence and trust in?—It should.—Can we properly have confidence, then, in something that is insecure?—No.—Pleasure contains no element of security, does it?—No.—Away with it, then, and throw it out of the balance, and drive it far away from the region of things good. But if you are not endowed with keen eyesight and if one balance is not enough for you, bring another. Can one properly feel elated over the good?—Yes.—Can one properly feel elated, then, over the moment's pleasure? See that you do not say that it is proper; if you do, I shall no longer regard you as a proper person even to have a balance!
And so are matters judged and weighed, if we have the standards ready with which to test them; and the task of philosophy is this—to examine and to establish the standards; but to go ahead and use them after they have become known is the task of the good and excellent man.
