In "Tehran Times" April 21, 2010, a short interview with Michael Walzer:
Q: Was the 20th century the best century in the history of philosophy? Why?
A: The century of Heidegger and Sartre? A century of willful obscurity and political idiocy. John Rawls is the towering exception, but he can’t save the century. Compare the era of Plato and Aristotle, or the era of Descartes and Spinoza, or the era of Hume and Kant. I don’t know how the relation of politics and philosophy works, but the 20th century was a time of tyranny, world war, and mass murder, and I would guess that that’s not a good time for philosophy. Certainly the response of philosophers was not anything to be proud of.
