On Eating
This was the sufficient sustenance of the Israelites. But that of the Gentiles was over-abundant. No one who uses it will ever study to become temperate, burying as he does his mind in his belly, very like the fish called ass, which, Aristotle says, alone of all creatures has its heart in its stomach. This fish Epicharmus the comic poet calls “monster-paunch.”
Such are the men who believe in their belly, “whose God is their belly, whose glory is in their shame, who mind earthly things.” To them the apostle predicted no good when he said, “whose end is destruction.”
