Idk about the modern meaning of virtue but doesn't "virtus" in roman mean something like "bravery" and "manliness". (Probably cognate to sanskrit "vIryam"
It isn't some modern meaning I'm referring to. I'm speaking of the general notion of virtue discussed by Aristotle or expressed in things like the four cardinal virtues (among which you will find courage, opposed to cowardice) and so on.
