Yes, those are what were classically considered the "liberal arts" (that is, the arts that were appropriate for free people, rather than slaves, who learned skills appropriate to the trades, if they learned anything at all). But no, when we currently talk about "liberal arts" (especially in a university setting), we no longer are talking about just those things. The term has changed meaning over the last 2000 years. When someone makes a post today, should assume their use of the term is today's use, not the use from the Greek and Roman era.
