“When Heidegger returned to teaching after his escapade as Nazi rector, one of his colleagues famously quipped, “Back from Syracuse?” The reference, of course, is to the three expeditions Plato made to Sicily in hopes of turning the young ruler Dionysius to philosophy and justice. The education failed, Dionysius remained a tyrant, and Plato barely escaped with his life. The parallel has been invoked more than once in discussions of Heidegger, the implication being that his tragicomic error was to have momentarily believed that philosophy could guide politics, especially the gutter politics of National Socialism.”
