6. First of all, tragedy was introduced to remind us that certain events happen, and are fated to happen as they do; and to teach us that what entertains us on the stage should not grieve us on the greater stage of the world. You see that such things must be accomplished; and that even they bore them who cried aloud, O Cithaeron! Our dramatic poets have said some excellent things; especially the following:—
Me and my children, if the Gods neglect,
It is for some good reason—
and again,
Vain is all anger at external things;
and,
To reap our life like ears of ripened corn—
and the like.
And after tragedy came the Old Comedy, using a schoolmaster’s freedom of speech, and employing plain language with great profit to inculcate the duty of humility. To this end Diogenes used a method much the same. Next consider the nature of the Middle Comedy; and lastly for what purpose the New was introduced, which gradually degenerated into the mere ingenuity of artificial mimicry. It is well known that some useful things were said by the New Comic Writers; but what useful end had they in view in all their accumulated poetry and playmaking?
7. How manifest it is that no other course of life was more adapted to the practice of philosophy than that which now is yours.
8. A branch cut off from its adjacent branch must necessarily be severed from the whole tree. Even so a man, parted from any fellow-man, has fallen away from the whole social community. Now a branch is cut off by some external agency; but a man by his own action separates himself from his neighbour—by hatred and aversion, unaware that he has thus torn himself away from the universal polity. Yet there is always given us the good gift of Zeus, who founded the great community, whereby it is in our power to be reingrafted on our kind, and to become once more, natural parts completing the whole. Yet the frequent happening of such separations, makes the reunion and restoration of the separated member more and more difficult. And in general a branch which has grown from the first upon a tree, and remained a living part of it, is not like one which has been cut and reingrafted; as the gardeners would say, they are of the same growth but of different persuasion.
