I cannot think, then, that Professor Max Müller’s contention that thought and language are identical—and he has repeatedly affirmed this—will ever be generally accepted. Thought is no more identical with language than feeling is identical with the nervous system. True, we can no more feel without a nervous system than we can discern certain minute organisms without a microscope. Destroy the nervous system, and we destroy feeling. Destroy the microscope, and we can no longer see the animalcules; but our sight of the animalcules is not the microscope, though it is effectuated by means of the microscope, and our feeling is not the nervous system, though the nervous system is the instrument that enables us to feel.
The nervous system is a device which living beings have gradually perfected—I believe I may say quite truly—through the will and power which they have derived from a fountain-head, the existence of which we can infer, but which we can never apprehend. By the help of this device, and in proportion as they have perfected it, living beings feel ever with great definiteness, and hence formulate their feelings in thought with more and more precision. The higher evolution of thought has reacted on the nervous system, and the consequent higher evolution of the nervous system has again reacted upon thought. These things are as power and desire, or supply and demand, each one of which is continually outstripping, and being in turn outstripped by the other; but, in spite of their close connection and interaction, power is not desire, nor demand supply. Language is a device evolved sometimes by leaps and bounds, and sometimes exceedingly slowly, whereby we help ourselves alike to greater ease, precision, and complexity of thought, and also to more convenient interchange of thought among ourselves. Thought found rude expression, which gradually among other forms assumed that of words. These reacted upon thought, and thought again on them, but thought is no more identical with words than words are with the separate letters of which they are composed.
To sum up, then, and to conclude. I would ask you to see the connection between words and ideas as in the first instance arbitrary. No doubt in some cases an imitation of the cry of some bird or wild beast would suggest the name that should be attached to it; occasionally the sound of an operation such as grinding may have influenced the choice of the letters g, r, as the root of many words that denote a grinding, grating, grasping, crushing action; but I understand that the number of words due to direct imitation is comparatively few in number, and that they have been mainly coined as the result of connections so far-fetched and fanciful as to amount practically to no connection at all. Once chosen, however, they were adhered to for a considerable time among the dwellers in any given place, so as to become acknowledged as the vulgar tongue, and raise readily in the mind of the inhabitants of that place the ideas with which they had been artificially associated.
As regards our being able to think and reason without words, the Duke of Argyll has put the matter as soundly as I have yet seen it stated. “It seems to me,” he wrote, “quite certain that we can and do constantly think of things without thinking of any sound or word as designating them. Language seems to me to be necessary for the progress of thought, but not at all for the mere act of thinking. It is a product of thought, an expression of it, a vehicle for the communication of it, and an embodiment which is essential to its growth and continuity; but it seems to me altogether erroneous to regard it as an inseparable part of cogitation.”
The following passages, again, are quoted from Sir William Hamilton in Professor Max Müller’s own book, with so much approval as to lead one to suppose that the differences between himself and his opponents are in reality less than he believes them to be.
“Language,” says Sir W. Hamilton, “is the attribution of signs to our cognitions of things. But as a cognition must have already been there before it could receive a sign, consequently that knowledge which is denoted by the formation and application of a word must have preceded the symbol that denotes it. A sign, however, is necessary to give stability to our intellectual progress—to establish each step in our advance as a new starting-point for our advance to another beyond. A country may be overrun by an armed host, but it is only conquered by the establishment of fortresses. Words are the fortresses of thought. They enable us to realize our dominion over what we have already overrun in thought; to make every intellectual conquest the base of operations for others still beyond.”
“This,” says Professor Max Müller, “is a most happy illustration,” and he proceeds to quote the following, also from Sir William Hamilton, which he declares to be even happier still.
“You have all heard,” says Sir William Hamilton, “of the process of tunnelling through a sandbank. In this operation it is impossible to succeed unless every foot, nay, almost every inch of our progress be secured by an arch of masonry before we attempted the excavation of another. Now language is to the mind precisely what the arch is to the tunnel. The power of thinking and the power of excavation are not dependent on the words in the one case or on the mason-work in the other; but without these subsidiaries neither could be carried on beyond its rudimentary commencement. Though, therefore, we allow that every movement forward in language must be determined by an antecedent movement forward in thought, still, unless thought be accompanied at each point of its evolutions by a corresponding evolution of language, its further development is arrested.”
Man has evolved an articulate language, whereas the lower animals seem to be without one. Man, therefore, has far outstripped them in reasoning faculty as well as in power of expression. This, however, does not bar the communications which the lower animals make to one another from possessing all the essential characteristics of language, and, as a matter of fact, wherever we can follow them we find such communications effectuated by the aid of arbitrary symbols covenanted upon by the living beings that wish to communicate, and persistently associated with certain corresponding feelings, states of mind, or material objects. Human language is nothing more than this in principle, however much further the principle has been carried in our own case than in that of the lower animals.
This being admitted, we should infer that the thought or reason on which the language of men and animals is alike founded differs as between men and brutes in degree but not in kind. More than this cannot be claimed on behalf of the lower animals, even by their most enthusiastic admirer.
