“Now, my dear friend,” continues the letter-writer, “it cannot be maintained that by the crawling system, exclusively adopted, men would arrive at the maximum amount of truth, even in any long series of ages; for the repression of imagination was an evil not to be counterbalanced even by _absolute_ certainty in the snail processes. But their certainty was very far from absolute. The error of our progenitors was quite analogous with that of the wiseacre who fancies he must necessarily see an object the more distinctly, the more closely he holds it to his eyes. They blinded themselves, too, with the impalpable, titillating Scotch snuff of _detail_; and thus the boasted facts of the Hog-ites were by no means always facts—a point of little importance but for the assumption that they always _were_. The vital taint, however, in Baconianism—its most lamentable fount of error—lay in its tendency to throw power and consideration into the hands of merely perceptive men—of those inter-Tritonic minnows, the microscopical savans—the diggers and pedlers of minute _facts_, for the most part in physical science—facts all of which they retailed at the same price upon the highway; their value depending, it was supposed, simply upon the _fact of their fact_, without reference to their applicability or inapplicability in the development of those ultimate and only legitimate facts, called Law. “Than the persons”—the letter goes on to say—“Than the persons thus suddenly elevated by the Hog-ian philosophy into a station for which they were unfitted—thus transferred from the sculleries into the parlors of Science—from its pantries into its pulpits—than these individuals a more intolerant—a more intolerable set of bigots and tyrants never existed on the face of the earth. Their creed, their text and their sermon were, alike, the one word ‘_fact_’—but, for the most part, even of this one word, they knew not even the meaning. On those who ventured to _disturb_ their facts with the view of putting them in order and to use, the disciples of Hog had no mercy whatever. All attempts at generalization were met at once by the words ‘theoretical,’ ‘theory,’ ‘theorist’—all _thought_, to be brief, was very properly resented as a personal affront to themselves. Cultivating the natural sciences to the exclusion of Metaphysics, the Mathematics, and Logic, many of these Bacon-engendered philosophers—one-idead, one-sided and lame of a leg—were more wretchedly helpless—more miserably ignorant, in view of all the comprehensible objects of knowledge, than the veriest unlettered hind who proves that he knows something at least, in admitting that he knows absolutely nothing.
