Rule Quotes - page 94
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.
Peter Sloterdijk
