Whoever is acquainted with the history of philosophy, during the last two or three centuries, cannot but admit that there appears to have existed a sort of secret and tacit compact among the learned, not to pass beyond a certain limit in speculative science. The privilege of free thought, so highly extolled, has at no time been held valid in actual practice, except within this limit; and not a single stride beyond it has ever been ventured without bringing obloquy on the transgressor. The few men of genius among the learned class, who actually did overstep this boundary, anxiously avoided the appearance of having so done. Therefore the true depth of science, and the penetration to the inmost centre, from which all the lines of knowledge diverge to their ever distant circumference, was abandoned to the illiterate and the simple, whom unstilled yearning, and an original ebulliency of spirit, had urged to the investigation of the indwelling and living ground of all things. These, then, because their names had never been enrolled in the guilds of the learned, were persecuted by the registered livery-men as interlopers on their rights and privileges. All without distinction were branded as fanatics and phantasts; not only those, whose wild and exorbitant imaginations had actually engendered only extravagant and grotesque phantasms, and whose productions were, for the most part, poor copies and gross caricatures of genuine inspiration; but the truly inspired likewise, the originals themselves. And this for no other reason, but because they were the unlearned, men of humble and obscure occupations. When, and from whom among the literati by profession, have we ever heard the divine doxology repeated, I thank thee, O Father! Lord of Heaven and Earth! because thou hast hid these things from the wise and prudent, and hast revealed them unto babes [28]. No; the haughty priests of learning not only banished from the schools and marts of science all who had dared draw living waters from the fountain, but drove them out of the very Temple, which mean time the buyers, and sellers, and money-changers were suffered to make a den of thieves.
