So what has happened to Dewey and Rorty in higher education?

They seem to be entirely absent from the philosophy departments of top flight universities, like University of Pennsylvania, and surprisingly Chicago.

Dewey is certainly and important academic in teacher training, especially in the field of reflection

Most American philosophy departments are strongly analytically oriented. Rorty started out as an analytical philosopher, but he got more and more “continental” as he got older (and as he gained fame beyond academic philosophy). Analytical philosophers do not like him for being too continental, and for the minority of “continental philosophy” specialists, he is not a real continental, so he doesn’t really count. Of course, being dead, he is not around to kick up a fuss about it, either.

Dewey, of course, has been dead a lot longer, and, like the vast majority of once-influential dead intellectuals, is now well into the process of being forgotten (although he has hung on to some shreds of relevance for longer than Rorty is likely to).

Dewey is not in danger of being forgotten as long as there are people who don’t like the “progressive education” trend that he helped to push forward. I personally think that this branch of malpractice would have gotten along very well without his help, e.g. Rothbard’s “Education Free and Compulsory” points out quite a few 19th century antecedents that had only very limited success because American people back then were more resistant to collectivist encroachment. Nevertheless, Dewey has become so culturally entrenched among the anti-progressives, that he is guaranteed his slot in collective memory as the anti poster boy for his ideology, as much as Hitler is for his.
