I'm hearing an echo of Francis Schaeffer here. He said (circa 1980) that we didn't really have philosophy anymore, we only had antiphilosophy. We had existentialism, which dealt with the big questions but was an antiphilosophy because it did so in an irrational way. And we had linguistic philosophy, which was rational but was an antiphilosophy because it didn't deal with the big questions.

In effect, Schaeffer said, our chairs of philosophy (at universities) are largely vacant. The real philosophy is being done by people outside of academic settings.
