4. Have I done something for the general interest? Well then I have had my reward. Let this always be present to thy mind, and never stop [doing such good]. 5. What is thy art? To be good. And how is this accomplished well except by general principles, some about the nature of the universe, and others about the proper constitution of man? 6. At first tragedies were brought on the stage as means of reminding men of the things which happen to them, and that it is according to nature for things to happen so, and that, if you are delighted with what is shown on the stage, you should not be troubled with that which takes place on the larger stage. For you see that these things must be accomplished thus, and that even they bear them who cry out, “O Cithaeron.” And, indeed, some things are said well by the dramatic writers, of which kind is the following especially:— “Me and my children if the gods neglect, This has its reason too.” And again,— “We must not chafe and fret at that which happens.” And,— “Life’s harvest reap like the wheat’s fruitful ear.” And other things of the same kind. After tragedy the old comedy was introduced, which had a magisterial freedom of speech, and by its very plainness of speaking was useful in reminding men to beware of insolence; and for this purpose too Diogenes used to take from these writers. But as to the middle comedy, which came next, observe what it was, and again, for what object the new comedy was introduced, which gradually sank down into a mere mimic artifice. That some good things are said even by these writers, everybody knows: but the whole plan of such poetry and dramaturgy, to what end does it look? 7. How plain does it appear that there is not another condition of life so well suited for philosophizing as this in which thou now happenest to be. 8. A branch cut off from the adjacent branch must of necessity be cut off from the whole tree also. So too a man when he is separated from another man has fallen off from the whole social community. Now as to a branch, another cuts it off; but a man by his own act separates himself from his neighbor when he hates him and turns away from him, and he does not know that he has at the same time cut himself off from the whole social system. Yet he has this privilege certainly from Zeus, who framed society, for it is in our power to grow again to that which is near to us, and again to become a part which helps to make up the whole. However, if it often happens, this kind of separation, it makes it difficult for that which detaches itself to be brought to unity and to be restored to its former condition. Finally, the branch, which from the first grew together with the tree, and has continued to have one life with it, is not like that which after being cut off is then ingrafted, for this is something like what the gardeners mean when they say that it grows with the rest of the tree, but that it has not the same mind with it.
