The theories about the origin of language have followed those about the origin of thought, and have shared their fate. The materialists have never been able to show the possibility of the first step. They attempt to veil their inability by the easy but fruitless assumption of an infinite space of time, destined to explain the gradual development of animals into men; as if millions of years could supply the want of the agent necessary for the first movement, for the first step in the line of progress! No numbers can effect a logical impossibility. How indeed could reason spring out of a state which is destitute of reason? How can speech, the expression of thought, develop itself in a year or in millions of years, out of unarticulated sounds which express feelings of pleasure, pain, and appetite? The common-sense of mankind will always shrink from such theories. Bunsen's words were echoed even more forcibly by professor Max Müller, speaking as President of the Anthropological Section of the British Association at Cardiff in 1889. What [he asked] does Bunsen consider the real barrier between man and beast? It is language, which is unattainable, or at least unattained, by any animal except man. You know [he continued] how for a time, and chiefly owing to Darwin's predominating influence, every conceivable effort was made to reduce the distance which language places between man and beast, and to treat language as a vanishing line in the mental evolution of animal and man. It required some courage at times to stand up against the authority of Darwin, but at present all serious thinkers agree, I believe, with Bunsen, that no animal has ever developed what we mean by rational language, as distinct from mere utterances of pleasure or pain, a subject lately treated with great fulness by Professor Romanes. Still, if all true science is based on facts, the fact remains that no animal has ever found what we mean by a language; and we are fully justified, therefore, in holding with Bunsen and Humboldt, as against Darwin and Romanes, that there _is_ a specific difference between the human animal and all other animals, and that that difference consists in language as the outward manifestation of what the Greeks meant by _Logos_.
