Here the same thing was repeated which occurred with the two parts of Kant's writings. The "Critique of Pure Reason," was accepted by science; but the "Critique of Practical Reason," that part which contains the essence of moral doctrine, was rejected. In the teaching of Comte, that was recognized to be scientific which humoured the reigning evil. But the Positive Philosophy accepted by the crowd, based on an arbitrary and incorrect supposition, was by itself too ill-grounded, and therefore too unsteady, and could not be sustained by itself. And now, among the idle play of ideas of so-called "Men of Science," there has appeared a similarly arbitrary and incorrect assertion, not at all new, to the effect that all living beings (that is, organisms), proceed one from another; not only one organism from another, but one organism from many; that during a very long period, a million of years, for instance, not only may a fish and a duck have proceeded from one and the same forefather, but also one organism might have proceeded from many separate organisms; so, for instance, out of a swarm of bees a single animal may proceed. This arbitrary and incorrect assertion was accepted by the learned world with still greater sympathy. The assertion was arbitrary, because no one has ever seen how one kind of organism is made from others; and therefore the hypothesis about the Origin of Species will always remain a mere supposition and never become an experimental fact. The hypothesis was incorrect, because the solution of the problem of the Origin of Species by the theory of the laws of inheritance and accommodation during an infinitely long period, is not a solution of the problem at all, but the mere reiteration of the question in another form. According to the solution of this problem by Moses (to oppose which is the object of Comte's theory), it appeared that the variety of the species of living beings proceeded from the will of God and his infinite omnipotence. According to the Theory of Evolution, it appears that the variety of species of living beings proceeded from themselves in consequence of the infinite variety of conditions of inheritance and environment in an infinite period of time. The Theory of Evolution, speaking plainly, asserts only that (by chance) in an infinite period of time, anything you like may proceed from anything else you choose. This is no answer to the question; it is simply the same question put differently: instead of Will is put Chance, and the co-efficient of the Infinite is transferred from Omnipotence to Time.
