In two journal articles, I came across a use of the infinitive in French that I'm not familiar with.
The first article is titled Enseigner la vertu?, and the second—which is a reply to the first—is titled Pouvoir enseigner la vertu?.
Both articles are about Plato's Meno, which concerns whether virtue is teachable. So I have a general idea that the first asks about teaching virtue and the reply asks about the ability to teach virtue.
However, I can't find any standard use of the infinitive in French that fits this context. Is it idiomatic? Or is there a standard use that I've missed in the grammars I've checked? (I would also be happy to hear what people think would be a good way to translate these titles, though I'm primarily concerned with understanding them rather than translation per se.)
