Looking for a known Greek/Roman quote/saying that expresses the opinion why the humanities are the only worthwhile subjects to study.
Yes, dad. I know studying Philosophy is a waste of time but as the Ancients said "____".
Something like the only worthwhile object of study is Man himself.
Googling around Greek, study, man was pretty uninformative, the only result I ended up with was Protagoras' Man is the measure of all things
which means something entirely different.
I originally saw this in a work of fiction, but can't remember the phrase, whether if it was a straight out reference to a known quote or if it was just paraphrasing what was probably the position of ancient Greek scholars.
