Wisdom of the Ages

Jay Nordlinger posts the following quote, in response to Slow Joe Biden's execrable remark that "these times require more than a good soldier, they require a wise leader" (directed at McCain, of course), courtesy of Thucydides*:

"The society that separates its scholars from its warriors will have its thinking done by cowards and its fighting done by fools."

I'm not terribly well-read in the Classics, and I consider this a major failing of my own education (the other being the lack of any "shop" type classes, although both of these are failings of modern pedagogy as a whole, I think). In fact, apart from some high school Homer and some Julius Caesar, I'm not "read" at all in that realm. But clearly there is much wisdom to be gained from such an exposure, so perhaps it's time I rectify that glaring omission in my own studies.

As for the content of what Biden said: okay, show me one genuinely wise thing Obama has done or said in his vast, expansive career. Just one! Please! That's all I'm asking...

*Update: Okay, maybe it was more recent than Thucydides. But I think my points still stand.
