Nothing has so stopped the progress of Darwin’s great conception as the injudicious efforts of his so-called disciples to bring it to perfection. Instead of correcting their chief, they should have weighed thoughtfully all Kant’s arguments against the materialism of his adversaries, and have sought to refute them; if they had succeeded in proving that Kant makes a mistake when he admits that there is in man a principle quite distinct from his body, they would have been authorised in replacing Darwin’s theory by their own; if they had not succeeded, Darwin and his theory would have remained unshaken, but they would be annihilated. Max Müller examines the question from another point of view. “We admit that as we know nothing, except by analogy, of the mind of animals, we could not with the weapons that Kant has placed in our hands, make head against the assertion that they might possess, for all we know, the same forms of sensuous intuition and the same categories of the understanding which we possess. Nothing, therefore, could have been said from a purely philosophical point of view, against treating man as a mere variety of some other genus of animals.”[65] But as the origin of language was to Kant less than a secondary question--it might almost be said to have no existence for him--it belongs to the science of language to show, what Kant had never shown, that for all human knowledge not only were percepts and concepts necessary, but also names. How was it that it did not occur to Kant since he perceived that there were mathematics of the forms or manifestations of sensation, namely, time or duration and space? He said well: Each object of which we think is attached in time or space to another; this can only be done by the use of such indications as _now_, _then_, _here_, _there_; and he saw in this gradation of perception, the first step towards the act of counting, that is to say of reasoning, and consequently of speaking; all of which was comprehended by the Greeks in their word Logos. As an instance the word _cent_ exists in every language, but _cent_ in French consists only of four letters placed side by side one after the other, and would never be anything else to us if we could not count; but to count is to add and to take away, that is to say, addition and subtraction, thus to conceive and name; in order to possess a hundred objects, it does not suffice to see them only, it is necessary to count them up to the hundred.
