I encounterd the phrase “because the barbarians require it” being used to describe people defending an action which they knew to be stupid but which they considered essential to ensure some others would agree to do something they did consider important.
It sounds like a quote from a classical author. Does anyone recognize it?
It does seem to catch the rough sense of the quote - maybe Cavafry was inspired to write his poam from some original quote. Or maybe I am wrong to assume that the person who I remember using the phrase was actually quoting anyone.
I can’t read Latin but I assume that that is the correct translation. It seems to me that Cicero is saying something quite different rather than “we” are doing some stupid because the barbarians require it that the barbarians are doing the same thing as everyone else but merely from necessity.
