Dewey
was the person credited with changing the American education system to what it is today. So he's the guy to thank for all the dumb kids out there.
Rorty just looked like he was full of his own psycho-progressive BS.
And Foucault? In 1975 he dropped acid at Zabriskie Point in Death Valley National Park, and called it the best experience of his life. And after the Iranian revolution he cozied up with the Mullahs.
And these are President Obama's lawyer's "major influences"???
Another influence I failed to mention was Jacques Derrida, sometimes considered the father of the Deconstructionist movement (largely responsible in my opinion for the death of modern philosophy, and the dismantling of American academic standards, but that's another story).
What many of these people have in common is their cultural roots as leftist radicals and their educational pedigrees as Ivy League graduates and later, as professors. Today, they are running your government.
