Symposiacs (1.2.6)

We all agreed that he said well, but asked him why he would not instruct us how to order things aright, and communicate his skill. I am content, says he, to instruct you, if you will permit me to change the present order of the feast, and will yield as ready obedience to me as the Thebans to Epaminondas when he altered the order of their battle. We gave him full power; and he, having turned all the servants out, looked round upon every one, and said: Hear (for I will tell you first) how I design to order you together. In my mind, the Theban Pammenes justly taxeth Homer as unskilful in love matters, for setting together, in his description of an army, tribe and tribe, family and family; for he should have joined the lover and the beloved, so that the whole body being united in their minds might perfectly agree. This rule will I follow, not set one rich

man by another, a youth by a youth, a magistrate by a magistrate, and a friend by a friend; for such an order is of no force, either to beget or increase friendship and good-will. But fitting that which wants with something that is able to supply it, next one that is willing to instruct I will place one that is as desirous to be instructed; next a morose, one good-natured; next a talkative old man, a youth patient and eager for a story; next a boaster, a jeering smooth companion; and next an angry man, a quiet one. If I see a wealthy fellow bountiful and kind, I will take some poor honest man from his obscure place, and set him next, that something may run out of that full vessel into the other empty one. A sophister I will forbid to sit by a sophister, and one poet by another;

For beggars beggars, poets poets, envy.[*]

I separate the clamorous scoffers and the testy, by putting some good-nature between them, that they may not justle so roughly on one another; but wrestlers, hunters, and farmers I put in one company. For some of the same nature, when put together, fight as cocks; others are very sociable as daws. Drinkers and lovers I set together, not only those who (as Sophocles says) feel the sting of masculine love, but those that are mad after virgins or married women; for they being warmed with the like fire, as two pieces of iron to be joined, will more readily agree; unless perhaps they both fancy the same person.
