Appropriate to a pig, the work of a swine. It is said that Socrates, in the presence of many others and Euthydemus himself, said that “Critias might seem to suffer from something swinish, wanting to rub himself against Euthydemus, just like piglets [do] against stones.” Xenophon says [this].[1]
Of swinish creatures:[2] “and this seemed to me to be the condition of guzzling swine rather than of human beings”. Plato [sc. says this] in Laws [book] 7.[3]
You are acting the pig: “when you talk of pigs and dog-headed people, you not only act like a pig yourself, but you act wrong in persuading your hearers to act so toward my writings”. Plato [sc. says this] in Theaetetus.[4]
