So, Antonis, judging from that post, if you don't understand something, you flap your hands rather than stopping to learn.
And if you don't understand someone, you accuse him of falseness of personality.
You know, this is a subject that's much larger. I have a relative who constantly refers to artisan trades as nothing, as work lazy or stupid people do by default. Of course she couldn't change the oil in her car. On the other hand, we all know people who think the liberal arts, or the soft sciences, are sheer prattery, nothing at all in the mouths of pretenders. As tho it were possible for such large enterprises over many generations to be nothing but pretense.
Do we really think we comprise in our own person and talents and experience everything that is worthwhile? That is not a logical conclusion. It is certainly not a generous one.
