After tragedy came ancient comedy, which was allowed to attack personal flaws. This freedom of speech was useful — it kept men from becoming too proud. That's why Diogenes also spoke this way. Later came Middle and New Comedy. But what were they really for? Mostly just to entertain people with clever imitation. 'It will steal away; watch out,' and so on. Sure, these plays had some good parts too. But what was the whole point of this kind of drama? Just what we said — entertainment.
After the tragedy, the ancient comedy was brought in, which had the liberty to inveigh against personal vices; being therefore through this her freedom and liberty of speech of very good use and effect, to restrain men from pride and arrogancy. To which end it was, that Diogenes took also the same liberty. After these, what were either the Middle, or New Comedy admitted for, but merely, (Or for the most part at least) for the delight and pleasure of curious and excellent imitation? 'It will steal away; look to it,' &c. Why, no man denies, but that these also have some good things whereof that may be one: but the whole drift and foundation of that kind of dramatical poetry, what is it else, but as we have said?
