Such as are thy habitual thoughts, such also will be the character of thy mind; for the soul is dyed by the thoughts. Dye it then with a continuous series of such thoughts as these: for instance, that where a man can live, there he can also live well. But he must live in a palace;- well then, he can also live well in a palace. And again, consider that for whatever purpose each thing has been constituted, for this it has been constituted, and towards this it is carried; and its end is in that towards which it is carried; and where the end is, there also is the advantage and the good of each thing. Now the good for the reasonable animal is society; for that we are made for society has been shown above. Is it not plain that the inferior exist for the sake of the superior? But the things which have life are superior to those which have not life, and of those which have life the superior are those which have reason.
Whether the universe is a concourse of atoms, or nature is a system, let this first be established, that I am a part of the whole which is governed by nature; next, I am in a manner intimately related to the parts which are of the same kind with myself. For remembering this, inasmuch as I am a part, I shall be discontented with none of the things which are assigned to me out of the whole; for nothing is injurious to the part, if it is for the advantage of the whole. For the whole contains nothing which is not for its advantage; and all natures indeed have this common principle, but the nature of the universe has this principle besides, that it cannot be compelled even by any external cause to generate anything harmful to itself. By remembering, then, that I am a part of such a whole, I shall be content with everything that happens. And inasmuch as I am in a manner intimately related to the parts which are of the same kind with myself, I shall do nothing unsocial, but I shall rather direct myself to the things which are of the same kind with myself, and I shall turn an my efforts to the common interest, and divert them from the contrary. Now, if these things are done so, life must flow on happily, just as thou mayest observe that the life of a citizen is happy, who continues a course of action which is advantageous to his fellow-citizens, and is content with whatever the state may assign to him.
There is no man so fortunate that there shall not be by him when he is dying some who are pleased with what is going to happen. Suppose that he was a good and wise man, will there not be at last some one to say to himself, Let us at last breathe freely being relieved from this schoolmaster? It is true that he was harsh to none of us, but I perceived that he tacitly condemns us.- This is what is said of a good man. But in our own case how many other things are there for which there are many who wish to get rid of us. Thou wilt consider this then when thou art dying, and thou wilt depart more contentedly by reflecting thus: I am going away from such a life, in which even my associates in behalf of whom I have striven so much, prayed, and cared, themselves wish me to depart, hoping perchance to get some little advantage by it. Why then should a man cling to a longer stay here? Do not however for this reason go away less kindly disposed to them, but preserving thy own character, and friendly and benevolent and mild, and on the other hand not as if thou wast torn away; but as when a man dies a quiet death, the poor soul is easily separated from the body, such also ought thy departure from men to be, for nature united thee to them and associated thee. But does she now dissolve the union? Well, I am separated as from kinsmen, not however dragged resisting, but without compulsion; for this too is one of the things according to nature.
