> I once tried to come up with a single-word purpose for education, and I landed upon the word “resourceful”

That seems pretty good. I might add "curious" and "skeptical."

> I landed upon the word “resourceful”

My 14 year old is pretty sharp and i like to pose philosophical questions that have no answer to him to watch the gears turn and see what he comes up with. I once asked him what he thought the meaning of life is and he replied "to make the most effective use of the resources available to you". I can't tell you if that came from him or something he read and, while not a perfect answer, i like it quite a bit.

capable, tenacious, kind

I really like that paragraph in the article. We have more access to knowledge and other resources than ever in history, and yet not everyone is a Renaissance Man.

Availability of resources does not entail skill in leveraging them. I'm not sure classical eduction is the best way to learn that, but it's certainly better than nothing and a useful first step.
