Diogenes ventured once to eat a raw pourcontrel, that he might disuse himself from meat dressed by fire; and as several priests and other people stood round him, he wrapped his head in his cassock, and so putting the fish to his mouth, he thus said unto them: It is for your sake, sirs, that I undergo this danger, and run this risk. A noble and gallant risk, by Jupiter! For far otherwise than as Pelopidas ventured his life for the liberty of the Thebans, and Harmodius and Aristogiton for that of the Athenians, did this philosopher encounter with a raw pourcontrel, to the end he might make human life more brutish. Moreover, these same flesh-eatings not only are preternatural to men’s bodies, but also by clogging and cloying them, they render their very minds and intellects gross. For it is well known to most, that wine and much flesh-eating make the body indeed strong and lusty, but the mind weak and feeble. And that I may not offend the wrestlers, I will make use of examples out of my own country. The Athenians are wont to call us Boeotians gross, senseless, and stupid fellows, for no other reason but our over-much eating; and Pindar calls us also hogs, for the same reason. Menander the comedian calls us fellows with long jaws. It is observed also that, according to the saying of Heraclitus, the wisest soul is like a dry light. Earthen jars, if you strike them, will sound; but if they be full, they perceive not the strokes that are given them. Copper vessels also that are thin communicate the sound round about them, unless some one stop and dull the ambient stroke with his fingers. Moreover, the eye, when seized with an over-great plenitude of humors, grows dim and feeble for its ordinary work. When we behold the sun through a humid air and a great quantity of gross and indigested vapors, we see it not clear and bright, but obscure and cloudy, and with glimmering beams. Just so in a muddy and clogged body, that is swagged down with heavy and unnatural nourishments; it must needs happen that the gayety and splendor of the mind be confused and dulled, and that it ramble and roll after little and scarce discernible objects, since it wants clearness and vigor for higher things.
