text: Now if the life of the gods contains nothing greater or better, and the happy life is divine, then there is no further height to which a man can be raised. Also, if the happy life is in want of nothing, then every happy life is perfect; it is happy and at the same time most happy. Have you any doubt that the happy life is the Supreme Good? Accordingly, if it possesses the Supreme Good, it is supremely happy. Just as the Supreme Good does not admit of increase (for what will be superior to that which is supreme?), exactly so the happy life cannot be increased either; for it is not without the Supreme Good. If then you bring in one man who is "happier" than another, you will also bring in one who is "much happier"; you will then be making countless distinctions in the Supreme Good; although I understand the Supreme Good to be that good which admits of no degree above itself. If one person is less happy than another, it follows that he eagerly desires the life of that other and happier man in preference to his own. But the happy man prefers no other man's life to his own. Either of these two things is incredible: that there should be anything left for a happy man to wish for in preference to what is, or that he should not prefer the thing which is better than what he already has. For certainly, the more prudent he is, the more he will strive after the best, and he will desire to attain it by every possible means. But how can one be happy who is still able, or rather who is still bound, to crave something else? I will tell you what is the source of this error: men do not understand that the happy life is a unit; for it is its essence, and not its extent, that establishes such a life on the noblest plane. Hence there is complete equality between the life that is long and the life that is short, between that which is spread out and that which is confined, between that whose influence is felt in many places and in many directions, and that which is restricted to one interest. Those who reckon life by number, or by measure, or by parts, rob it of its distinctive quality. Now, in the happy life, what is the distinctive quality? It is its fulness. Satiety, I think, is the limit to our eating or drinking. A eats more and B eats less; what difference does it make? Each is now sated. Or A drinks more and B drinks less; what difference does it make? Each is no longer thirsty. Again, A lives for many years and B for fewer; no matter, if only A's many years have brought as much happiness as B's few years. He whom you maintain to be "less happy" is not happy; the word admits of no diminution.
