From The Chronicle:
Anyone who has been paying attention to the fault lines of academic debate for the past 20 years already knows that the “science wars” were fought by natural scientists (and their defenders in the philosophy of science) on the one side and literary critics and cultural-studies folks on the other. The latter argued that even in the natural realm, truth is relative, and there is no such thing as objectivity. The skirmishes blew up in the well-known “Sokal affair” in 1996, in which a prominent physicist created a scientifically absurd postmodernist paper and was able to get it published in a leading cultural-studies journal. The ridicule that followed may have seemed to settle the matter once and for all.
