"For as long as possible, the learned collegium has tried to defend its integrity against the close combat of ideologico-critical exposures. Do not unmask, lest you yourself be unmasked could be the unspoken rule. It is no accident that the great representatives of critique—the French moralists, the Encyclopedists, the socialists, and especially Heine, Marx, Nietzsche, and Freud—remain outsiders to the scholarly domain. In all of them there is a satirical, polemical component that can scarcely be hidden under the mask of scholarly respectability. These signals of a holy nonseriousness, which remains one of the sure indexes of truth, can be employed as signposts to the critique of cynical reason."
