The bitter laugh still curls our lips, elicited by his merciless satire, when the tears of pity come coursing down our cheeks, as he touches with magic finger the most godlike fibres of the soul. Luxuriance, bordering on levity, follows fast a sense of justice and of truth, that might have put a Brutus and an Aristides to the blush. National contrasts, harmonies, and deformities, all seem reflected in this representative man. Yet it would be a very partial view that represented Fourier as nothing better than an expletive particle added to the genealogical list of idea-mongers, or a mosaic of valuable relics in earth's cabinet of curiosities. Though his pen inflicts wounds both broad and deep, yet a balm is ever at hand. Not satisfied with performing amputations for the good of the body corporate, he is a professor of the healing art, and affects to have discovered an elixir that shall wipe away all tears, by causing pain and sorrow to flee away. I do not profess to judge of the merits of the case, but one feature distinguishes Fourier from critics, reformers, and prophets, who are gathered to their fathers. He is a _scientific_ explorer, and the plans that he has designed for the future structure of humanity, from the high order of architecture and mechanics which they exhibit, discriminate him from the vulgar herd as an originator, and place him in the category either of eminent scientific adventurers or inventors. Daring and caution shake hands at every page, and seem exhausted by his pen. The Archimedian lever found a resting-place in his brain, and sundry of his thoughts seem not inapt to upheave the world. If Laplace deserves credit as the creator of a Mechanique Celeste, Fourier has equal claims to gratitude as the first and only propounder of a rigidly scientific system of mental mechanics. Though Pythagoras might smile complacently at his harmonies and sacred numbers, and Plato clap his hands on seeing so worthy a disciple of his Republic, yet the fiery Frenchman is but too apt to run counter to the past, and give a slap in the face to the wisdom of the fore-world. Though hope and faith ever brighten his pages, we could wish at times for a larger infusion of charity, to neutralize the gall in which his pen was dipped. Yet he nobly vindicates his claim as a reformer by the lash he applies with no measured hand to injustice, falseness, and hypocrisy, under whatever guise they may appear.
