Actually, you are describing in perfect detail all of my humanities professors in college. They would just ramble on from one idea to another, and apparently we were supposed to see the grand connection between them, but to this day I suspect that it's just the way Ph.D.s love to convince themselves of how smart they are. And that's most of the reason why I so despised my humanities courses.
I think Gore would have been very happy as a college professor. He could ramble on all day about how brilliant he is, never having to make any sense, and he'd have hordes of liberal college kid groupies.
Only in the humanities, as you said. In the hard sciences, math, or engineering he'd be expected to produce objectively verifiable results.
