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 à 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 the advent of one Hog, surnamed the “Ettrick Shepherd,” who preached an entirely different system, which he called the à posteriori or inductive. His plan referred altogther [C,E: altogether] to Sensation. He proceeded by observing, analyzing and classifying facts—instantiæ naturæ, 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 that 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. The ancient idea confined investigation to crawling; and for hundreds of years so great was the infatuation about Hog especially, that a virtual end was put to all thinking properly so called. No man dared utter a truth for which he felt himself indebted to his Soul alone. It mattered not whether the truth was even demonstrably a ·1296· truth, for the bullet-headed savans of the time regarded only the road by which he had attained it. They would not even look at the end. “Let us see the means,” they cried, “the means!” If, upon investigation of the means, it was found to come neither under the category Aries (that is to say Ram) nor under the category Hog, why then the savans went no farther, but pronounced the “theorist” a fool, and would have nothing to do with him or his truth.
Now, it cannot be maintained, even, that by the crawling system the greatest amount of truth would be attained in any long series of ages, for the repression of imagination was an evil not to be compensated for by any superior certainty in the ancient modes of investigation. The error of these Jurmains, these Vrinch, these Inglitch and these Amriccans, (the latter, by the way, were our own immediate progenitors,) was an error quite analogous with that of the wiseacre who fancies that he must necessarily see an object the better the more closely he holds it to his eyes. These people blinded themselves by details. When they proceeded Hoggishly, their “facts” were by no means always facts—a matter of little consequence had it not been for assuming that they were facts and must be facts because they appeared to be such. When they proceeded on the path of the Ram, their course was scarcely as straight as a ram’s horn, for they never had an axiom which was an axiom at all. They must have been very blind not to see this, even in their own day; for even in their own day many of the long “established” axioms had been rejected. For example—“Ex nihilo nihil fit;” “a body cannot act where it is not;” “there cannot exist antipodes;” “darkness cannot come out of light”—all these, and a dozen other similar propositions, formerly admitted without hesitation as axioms, were, even at the period of which I speak, seen to be untenable. How absurd in these people, then, to persist in putting faith in “axioms” as immutable bases of Truth! But even out of the mouths of their soundest reasoners it is easy to demonstrate the futility, the impalpability of their axioms in general. Who was the soundest of their logicians? Let me see! I will go and ask Pundit and be back in a minute ………….. Ah, here we have it! Here is a book written nearly a thousand years ago and lately translated from the Inglitch—which, by the way, appears to have been the rudiment of ·1297· the Amriccan. Pundit says it is decidedly the cleverest ancient work on its topic, Logic. The author (who was much thought of in his day) was one Miller, or Mill; and we find it recorded of him, as a point of some importance, that he had a mill-horse called Bentham. But let us glance at the treatise!
Ah!—“Ability or inability to conceive,” says Mr. Mill, very properly, “is in no case to be received as a criterion of axiomatic truth.” What modern in his senses would ever think of disputing this truism? The only wonder with us must be, how it happened that Mr. Mill conceived it necessary even to hint at anything so obvious. So far good—but let us turn over another page. What have we here?—“Contradictories cannot both be true—that is, cannot co-exist in nature.” Here Mr. Mill means, for example, that a tree must be either a tree or not a tree—that it cannot be at the same time a tree and not a tree. Very well; but I ask him why. His reply is this—and never pretends to be anything else than this—“Because it is impossible to conceive that contradictories can both be true.” But this is no answer at all, by his own showing; for has he not just admitted as a truism that “ability or inability to conceive is in no case to be received as a criterion of axiomatic truth?”
Now I do not complain of these ancients so much because their logic is, by their own showing, utterly baseless, worthless and fantastic altogether, as because of their pompous and imbecile proscription of all other roads of Truth, of all other means for its attainment than the two preposterous paths—the one of creeping and the one of crawling—to which they have dared to confine the Soul that loves nothing so well as to soar.
By the by, my dear friend, do you not think it would have puzzled these ancient dogmaticians to have determined by which of their two roads it was that the most important and most sublime of all their truths was, in effect, attained? I mean the truth of Gravitation. Newton owed it to Kepler. Kepler admitted that his three laws were guessed at—these three laws of all laws which led the great Inglitch mathematician to his principle, the basis of all physical principle—to go behind which we must enter the Kingdom of Metaphysics. Kepler guessed—that is to say, imagined. He was essentially a “theorist”—that word now of so much ·1298· sanctity, formerly an epithet of contempt. Would it not have puzzled these old moles, too, to have explained by which of the two “roads” a cryptographist unriddles a cryptograph of more than usual secrecy, or by which of the two roads Champollion directed mankind to those enduring and almost innumerable truths which resulted from his deciphering the Hieroglyphics?
One word more on this topic and I will be done boring you. Is it not passing strange that, with their eternal prating about roads to Truth, these bigoted people missed what we now so clearly perceive to be the great highway—that of Consistency? Does it not seem singular how they should have failed to deduce from the works of God the vital fact that a perfect consistency must be an absolute truth! How plain has been our progress since the late announcement of this proposition! Investigation has been taken out of the hands of the ground-moles and given, as a task, to the true and only true thinkers, the men of ardent imagination. These latter theorize. Can you not fancy the shout of scorn with which my words would be received by our progenitors were it possible for them to be now looking over my shoulder? These men, I say, theorize; and their theories are simply corrected, reduced, systematized—cleared, little by little, of their dross of inconsistency—until, finally, a perfect consistency stands apparent which even the most stolid admit, because it is a consistency, to be an absolute and an unquestionable truth.
