populate all the submarine portions of the globe.'[44] Although the writers of this delicious drollery seem to have had Dr. Erasmus Darwin only in view, they could not, we thus see, parody his peculiar crotchets without hitting off not less neatly some of the corresponding extravagances of both earlier and later expounders of Nature. Nature is a phrase which, greatly to the confusion of those who so employ it, is habitually used simultaneously in two quite opposite senses, so as to denote at the same time both the agency in virtue of whose action the universe exists, and likewise the universe itself which results from that action. Nature, in either signification, becomes to a great extent interpretable when the agency so designated is credited with sufficient sense to foresee and to intend the results of its own action. On that condition, although among the many unsolved problems she may continue to present there will be some evidently lying beyond the limits of human comprehension, there will be none running counter to human reason. Except on that condition, the universe is not simply uninterpretable, it is a bewildering assemblage of irreconcilable certainties. Philosophy's choice lies between such patent truisms as that there can be no force but living force, no _vis_ but _vis vivida_, no _vis inertiae_ otherwise than metaphorically, and such blatant falsisms as that inertness and exertion may coincide, unintelligence generate intelligence, agency of whatsoever sort produce, merely by its own act, and merely out of its own essence, other agency capable of higher action than its own. Philosophy, when with these sets of alternatives before her she deliberately chooses the latter, becomes Scientific Atheism, all the varieties of which have one point in common, resembling each other in their proneness to rush upon and embrace demonstrable impossibilities for the sake of avoiding a few things hard to be understood. One variety, however, the Comtist, far exceeds all the rest in the lengths to which it is carried by this propensity. IV. If, in speaking as I am about to do of Comtism, I commit--heedless of Mr. Lewes' solemn warning--the grave offence of speaking confidently about a writer whom I have never read, I may at least plead in extenuation of my fault, that, although my knowledge of that writer be confessedly merely an echo of what others have said of him, those others, at any rate, far from being his antagonists, are two of the most ardent of his not undiscriminating admirers. It is from Mr. Mill[45] and from Mr. Lewes[46] himself that I have derived the notions of Comtist philosophy that suggest to me the following notes.
