Isocrates the rhetorician, when at a drinking bout some begged him to make a speech, only returned: With those things in which I have skill the time doth not suit; and in those things with which the time suits I have no skill.
And Crato cried out: By Bacchus, he was right to forswear talk, if he designed to make such long-winded discourses as would have spoiled all mirth and conversation; but I do not think there is the same reason to forbid philosophy as to take away rhetoric from our feasts.

For philosophy is quite of another nature; it is an art of living, and therefore must be admitted into every part of our conversation, into all our gay humors and our pleasures, to regulate and adjust them, to proportion the time, and keep them from excess; unless, perchance, upon the same scoffing pretence of gravity, they would banish temperance, justice, and moderation.

It is true, were we to feast before a court, as those that entertained Orestes, and were silence enjoined by law, that might prove no mean cloak of our ignorance; but if Bacchus is really [Greek omitted] (A LOOSER of everything), and chiefly takes off all restraints and bridles from the tongue, and gives the voice the greatest freedom, I think it is foolish and absurd to deprive that time in which we are usually most talkative of the most useful and profitable discourse; and in our schools to dispute of the offices of company, in what consists the excellence of a guest, how mirth, feasting, and wine are to be used and yet deny philosophy a place in these feasts, as if not able to confirm by practice what by precepts it instructs.
And when you affirmed that none ought to oppose what Crato said, but determine what sorts of philosophical topics were to be admitted as fit companions at a feast, and so avoid that just and pleasant taunt put upon the wrangling disputers of the age, Come now to supper, that we may contend; and when you seemed concerned and urged us to speak to that head, I first replied: Sir, we must consider what company we have; for if the greater part of the guests are learned men,--as for instance, at Agatho's entertainment, characters like Socrates, Phaedrus, Pausanias, Euryximachus; or at Callias's board, Charmides, Antisthenes, Hermogenes, and the like,--we will permit them to philosohize, and to mix Bacchus with the Muses as well as with the Nymphs; for the latter make him wholesome and gentle to the body, and the other pleasant and agreeable to the soul.

And if there are some few illiterate persons present, they, as consonants with vowels, in the midst of the other learned, will participate not altogether inarticulately and insignificantly.

But if the greater part consists of such who can better endure the noise of any bird, fiddle-string, or piece of wood than the voice of a philosopher, Pisistratus hath shown us what to do; for being at difference with his sons, when he heard his enemies rejoiced at it, in a full assembly he declared that he had endeavored to persuade his sons to submit to him, but since he found them obstinate, he was resolved to yield and submit to their humors.
