“It may seem as though I had met with an evil recompense from the gods for my conduct in adhering to what I think just and virtuous; but it only seems so, and so long as I succeed in living in accordance with nature, which obeys an everlasting law, no man is justified in accusing me. My own peace of mind especially will never desert me so long as I do not set myself to act in opposition to the fundamental convictions of my inmost being, but obey the doctrines of Zeno and Chrysippus. This peace every one may preserve, aye, even you, a woman, if you constantly do what you recognize to be right, and fulfil the duties you take upon yourself. The very god himself is proof and witness of this doctrine, for he grants to him who obeys him that tranquillity of spirit which must be pleasing in his eyes, since it is the only condition of the soul in which it appears to be neither fettered and hindered nor tossed and driven; while he, on the contrary, who wanders from the paths of virtue and of her daughter, stern duty, never attains peace, but feels the torment of an unsatisfied and hostile power, which with its hard grip drags his soul now on and now back.
“He who preserves a tranquil mind is not miserable, even in misfortune, and thankfully learns to feel con tented in every state of life; and that because he is filled with those elevated sentiments which are directly related to the noblest portion of his being--those, I mean--of justice and goodness. Act then, my child, in conformity with justice and duty, regardless of any ulterior object, without considering whether your action will bring you pleasure or pain, without fear of the judgment of men or the envy of the gods, and you will win that peace of mind which distinguishes the wise from the unwise, and may be happy even in adverse circumstances; for the only real evil is the dominion of wickedness, that is to say the unreason which rebels against nature, and the only true happiness consists in the possession of virtue. He alone, however, can call virtue his who possesses it wholly, and sins not against it in the smallest particular; for there is no difference of degrees either in good or in evil, and even the smallest action opposed to duty, truth or justice, though punishable by no law, is a sin, and stands in opposition to virtue.
