But in all ages the great obstacles to advancement in Art have been opposed by the so-called men of science. To be sure, our men of science are not quite so bigoted as those of old:—oh, I have something so queer to tell you on this topic. Do you know that it is not more than a thousand years ago since the metaphysicians consented to relieve the people of the singular fancy that there existed but two possible roads for the attainment of Truth! Believe it if you can! It appears that long, long ago, in the night of Time, there lived a Turkish philosopher (or Hindoo possibly) called Aries Tottle. This person introduced, or at all events propagated what was termed the deductive or a priori mode of investigation. He started with what he maintained to be axioms or "self-evident truths," and thence proceeded "logically" to results. His greatest disciples were one Neuclid, and one Cant. Well, Aries Tottle flourished supreme until advent of one Hog, surnamed the "Ettrick Shepherd," who preached an entirely different system, which he called the a posteriori or inductive. His plan referred altogether to Sensation. He proceeded by observing, analyzing, and classifying facts-instantiae naturae, as they were affectedly called—into general laws. Aries Tottle's mode, in a word, was based on noumena; Hog's on phenomena. Well, so great was the admiration excited by this latter system that, at its first introduction, Aries Tottle fell into disrepute; but finally he recovered ground and was permitted to divide the realm of Truth with his more modern rival. The savans now maintained the Aristotelian and Baconian roads were the sole possible avenues to knowledge. "Baconian," you must know, was an adjective invented as equivalent to Hog-ian and more euphonious and dignified.

Now, my dear friend, I do assure you, most positively, that I represent this matter fairly, on the soundest authority and you can easily understand how a notion so absurd on its very face must have operated to retard the progress of all true knowledge—which makes its advances almost invariably by intuitive bounds.
