“The situation in which “everything is possible” is, indeed, Arendt’s diagnosis of what is distinctly totalizing in totalitarian dictatorship. It is the world-historically unique manifestation of the human capacity to will a world existing “only in ideas” (ideology) into actual reality. If we fail to achieve a sense of impartiality—what Arendt calls a “common sense”—then what is lost, along with the democratic warrant for the pursuit of truth (factual as well as rational), is the common world altogether.”
