The long and short of it: education good, no curiosity and illiteracy, bad. ;)
That does seem to be the point, doesn't it?
I'm wondering about a couple of things.
First of all, the ideas summarized in your two quoted paragraphs are clearly oversimplifications. In fact,
they seem to confirm some rather old stereotypes about the radical difference between Northern versus Southern European cultures, along with assertions of the superiority of the former over the latter..
Also, as ballet lovers, shouldn't we be a bit on the side of the "liturgists"?. Reading can't tell us everything we need to know, Nor can intellectual analysis. Sometimes "doing" something in a serious, committed, even sacred manner (either as ritual, or dance, or other performance art) is an equally profound way of accessing knowledge.
Which suggests that an active education in the arts is something that ideally should go hand in hand with the kind of intellectual training that the writers of the article above are advocating. Thinking in terms of the paragraphs quoted above, we might think of this as a union
of "Northern" and "Southern" European types, both of which are of great value to us as individuals and as culture.
