It's all fine and good to be a skeptic in the Rortian vein or Stanley Fish-style and argue that metaphysics and foundationalism are bunk and that democracy doesn't need any sort of philosophical grounding.
The problem is that there is trickle-down of ideas: not directly from academia to the average citizen, but from philosophers to the media elite, who are mostly college-educated and whose views of reality and discourse are a kind of cartoon version of the dominant trends in academic thought.
You wonder then where the MSM gets this idea that empiricism doesn't matter, that reality is just a construct, that public life is nothing but a power-struggle in which the right thing to do is find out what the daddy-party wants, and just obey that?
Look no further than Rorty, Fish, and the two-bit latter-day deconstructionists.
Ideas have consequences, and so does the weak-tea thesis that ideas themselves are inconsequential. Without a strong commitment to truth, empiricism, and foundationalism in ideas, all you have left is tribalism on right, and triangulation on the left.
I've been making fun of the following Wilber quote:
"The single greatest problem was stated this way. When green attacks orange, amber wins. And believe me, amber is winning, just ask Karl Rove. Despite a democratic victory here or there, the ranks of voters have downshifted towards amber, unmistakably and strongly. All of this thanks to the likes of green Harvard, which has finally succeeded in deconstructing it's own deconstructionists"
I think I may have to take back my fun-making. That quote above - coming from a completely different place than Wilber - essentially says the same thing.
Something to think about.
