“ The notion of literature as only one of several avenues to a single typeof propositional knowledge is, of course, hardly the winning ticket in lit-crit today. More typical are sentiments that see such a notion as not even admissible, if at all desirable. The world of these academic refuseniks is, however, a bleak and sterile place. Disarmed by their own epistemic fiat, scholars cannot assert anything since they deny the idea of objective rationality. If they arrive at an insight whose truth they wish to defend – for example that truth and rationality are passé – they can’t do so because truth and rationality are constructed to be constructed. ”
