And why to you more than the Syrians, or to the Egyptians? Why more than to me or to any other man? Not at all more. Seeming, then, doth not for every man answer to Being; for neither in weights or measures doth the bare appearance content us, but for each case we have discovered some rule. And here, then, is there no rule above seeming? And how could it be that there were no evidence or discovery of things the most necessary for men? There is, then, a rule. And wherefore do we not seek it, and find it, and, having found it, henceforth use it without transgression, and not so much as stretch forth a finger without it? For this it is, I think, that when it is discovered cureth of their madness those that mismeasure all things by seeming alone; so that henceforth, setting out from things known and investigated, we may use an organized body of natural conceptions in all our several dealings. 5. What is the subject about which we are inquiring? Pleasure? Submit it to the rule, cast it into the scales. Now the Good must be a thing of such sort that we ought to trust in it? _Truly._ And we ought to have faith in it? _We ought._ And ought we to trust in anything which is unstable? _Nay._ And hath pleasure any stability? _It hath not._ Take it, then, and fling it out of the scales, and set it far away from the place of the Good. But if you are dim of sight, and one balance doth not suffice, then take another. Is it right to be elated in what is good? _Yea._ And is it right to be elated then in the presence of a pleasure? See to it that thou say not it is right; or I shall not hold thee worthy even of the balance.[3] Thus are things judged and weighed, when the rules are held in readiness. And the aim of philosophy is this, to examine and establish the rules. And to use them when they are known is the task of a wise and good man. CHAPTER II. ON THE NATURAL CONCEPTIONS. 1. The natural conceptions are common to all men, and one cannot contradict another. For which of us but affirms that the Good is profitable, and that we should choose it, and in all circumstances follow and pursue it? Which of us but affirms that uprightness is honorable and becoming? Where, then, doth the contradiction arise? Concerning the application of the natural conceptions to things severally. When one saith, _He did well, he is a worthy man_, and another, _Nay, but he did foolishly_, then there is a contradiction among men, one with another. And there is the same contradiction among the Jews and the Syrians and the Egyptians and the Romans; not whether that which is righteous should be preferred to all things and in all cases pursued, but whether this be righteous or unrighteous, to eat the flesh of swine. And ye can discover the same contradiction in the matter of Achilles and Agamemnon. For call them before us: What sayest thou, Agamemnon, Should not that which is right and fair come to pass? ——“That should it.”
