But it is quite ridiculous for a man to speak and decide like a genius in things which require the most careful investigation by Reason. One does not know whether to laugh more at the impostor who spreads such a mist round him that we cannot clearly use our Judgement and so use our Imagination the more, or at the public which na�vely imagines that his inability to cognise clearly and to comprehend the masterpiece before him arises from new truths crowding in on him in such abundance that details (duly weighed definitions and accurate examination of fundamental propositions) seem but clumsy work.
