"There is perhaps nothing more interesting than to listen to a superior man talk of what he does not know. He advances slowly, and scarcely puts his foot down without knowing if the ground is solid; he looks for plausible analogies; he tries to attach his ideas to higher and incontestable principles; he always has the tone of looking, never that of teaching; and it often happens that, even if he is mistaken, he leaves a great enough idea of his mental honesty."
