My host, however, had in some degree resumed the calmness of his demeanor, and questioned me very rigorously in respect to the conformation of the visionary creature. When I had fully satisfied him on this head, he sighed deeply, as if relieved of some intolerable burden, and went on to talk, with what I thought a cruel calmness, of various points of speculative philosophy, which had heretofore formed subject of discussion between us. I remember his insisting very especially (among other things) upon the idea that the principle source of error in all human investigations lay in the liability of the understanding to under-rate or to over-value the importance of an object, through mere mis-admeasurement of its propinquity. «To estimate properly, for example,» he said, «the influence to be exercised on mankind at large by the thorough diffusion of Democracy, the distance of the epoch at which such diffusion may possibly be accomplished should not fail to form an item in the estimate. Yet can you tell me one writer on the subject of government who has ever thought this particular branch of the subject worthy of discussion at all?»
