In the consideration of the faculties and impulses -- of the prima mobilia of the human soul, the phrenologists have failed to make room for a propensity which, although obviously existing as a radical, primitive, irreducible sentiment, has been equally overlooked by all the moralists who have preceded them. In the pure arrogance of the reason, we have all overlooked it. We have suffered its existence to escape our senses solely through want of belief -- of faith; -- whether it be faith in Revelation, or faith in the Kabbala. The idea of it has never occurred to us, simply because of its supererogation. We saw no need of impulse -- for the propensity. We could not perceive its necessity. We could not understand, that is to say, we could not have understood, had the notion of this primum mobile ever obtruded itself; -- we could not have understood in what manner it might be made to further the objects of humanity, either temporal or eternal. It cannot be denied that phrenology and, in great measure, all metaphysicianism have been concocted a priori. The intellectual or logical man, rather than the understanding or observant man, set himself to imagine designs -- to dictate purposes to God. Having thus fathomed, to his satisfaction, the intentions of Jehovah, out of these intentions he built his innumerable systems of mind. In the matter of phrenology, for example, we first determined, naturally enough, that it was the design of the Deity that man should eat. We then assigned to man an organ of alimentiveness, and this organ is the scourge with which the Deity compels man, will-I nill-I, into eating.
The Imp of the Perverse by Poe, Edgar Allan, 1809-1849
