text: I shall tell you what I mean by health: if the mind is content with its own self; if it has confidence in itself; if it understands that all those things for which men pray, all the benefits which are bestowed and sought for, are of no importance in relation to a life of happiness; under such conditions it is sound. For anything that can be added to is imperfect; anything that can suffer loss is not lasting; but let the man whose happiness is to be lasting, rejoice in what is truly his own. Now all that which the crowd gapes after, ebbs and flows. Fortune gives us nothing which we can really own. But even these gifts of Fortune please us when reason has tempered and blended them to our taste; for it is reason which makes acceptable to us even external goods that are disagreeable to use if we absorb them too greedily. Attalus used to employ the following simile: "Did you ever see a dog snapping with wide-open jaws at bits of bread or meat which his master tosses to him? Whatever he catches, he straightway swallows whole, and always opens his jaws in the hope of something more. So it is with ourselves; we stand expectant, and whatever Fortune has thrown to us we forthwith bolt, without any real pleasure, and then stand alert and frantic for something else to snatch." But it is not so with the wise man; he is satisfied. Even if something falls to him, he merely accepts it carelessly and lays it aside. The happiness that he enjoys is supremely great, is lasting, is his own. Assume that a man has good intentions, and has made progress, but is still far from the heights; the result is a series of ups and downs; he is now raised to heaven, now brought down to earth. For those who lack experience and training, there is no limit to the downhill course; such a one falls into the Chaos of Epicurus, – empty and boundless. There is still a third class of men, – those who toy with wisdom; they have not indeed touched it, but yet are in sight of it, and have it, so to speak, within striking distance. They are not dashed about, nor do they drift back either; they are not on dry land, but are already in port.
