That is the argument of John McCumber, a scholar of Hegel and Heidegger who himself decamped from philosophy to German. His book Time in the Ditch: American Philosophy and the McCarthy Era (Northwestern University Press, 2001) savages the contemporary American philosophical profession and its flight from history. He notes, for instance, that 10 years after the 1987 "breakthrough anthology" Feminism as Critique, not one of its contributors, from Seyla Benhabib to Iris Marion Young, still taught in a philosophy department. The pressures that force — or tempt — big names such as Rorty and Martha Nussbaum to quit philosophy, McCumber observes, exert equal force on those outside the public eye. He charges, for instance, that senior editors dispense with peer review and run the major philosophy journals like private fiefdoms, and that a few established professors select papers for the discipline's annual conferences. The authoritarianism and cronyism drive out mavericks.I expect journals rise and fall based on their quality (As calculated by citations?). Today mavericks have the internet to work around the inefficiencies in traditional academic publishing; witness this story in the New Yorker on Garrett Lisi publishing his paper on E8 and the Standard Model.
