WE KNOW WE HAVE REACHED HAPPINESS WHEN WE NO MORE DESIRE ANYTHING.
That the man who has achieved perfect Life possesses happiness is proved by his no longer desiring anything. What more could he desire? He could not desire anything inferior; he is united to the best; he, therefore, has fulness of life. If he be virtuous he is fully happy, and fully possesses the Good, for no good thing escapes him. What he seeks is sought only by necessity, less for him than for some of the things which belong to him. He seeks it for the body that is united to him; and though this body be endowed with life, what relates to his needs is not characteristic of the real man. The latter knows it, and what he grants to his body, he grants without in any way departing from his own characteristic life. His happiness will, therefore, not be diminished in adversity, because he continues to possess veritable life. If he lose relatives or friends, he knows the nature of death, and besides those whom it strikes down know it also if they were virtuous. Though he may allow himself to be afflicted by the fate of these relatives or friends, the affliction will not reach the intimate part of his nature; the affliction will be felt only by that part of the soul which lacks reason, and whose suffering the man will not share.
