Seneca · On the proper style for a philosopher's discourse
Letters 40.2
You write me that you heard a lecture by the philosopher Serapio, when he landed at your present place of residence. “He is wont,” you say, “to wrench up his words with a mighty rush, and he does not let them flow forth one by one, but makes them crowd and dash upon each other. For the words come in such quantity that a single voice is inadequate to utter them.” I do not approve of this in a philosopher; his speech, like his life, should be composed; and nothing that rushes headlong and is hurried is well ordered. That is why, in Homer, the rapid style, which sweeps down without a break like a snow-squall, is assigned to the younger speaker; from the old man eloquence flows gently, sweeter than honey.
