Introduction to the Study of the History of Language

It is the province of the Science of Language to explain, as far as possible, the processes of the development of Language from its earliest to its latest stage. The observations made on these processes would naturally be registered in different historical grammars of different definite languages; these grammars would follow the different steps in the development of each single language from its earliest traditional origin to its most recent phase. Wider and more general observations on the processes of this development would naturally be expressed in a comparative grammar, whose task would be to examine and compare the relations between cognate families of speech, the common origin of which is lost: but it would in this case be necessary to insist that the comparisons instituted should only be between languages in the same stage of development; or that the same stage of development, in each of the languages selected for comparison, should be taken for the purpose.

It is the task of Descriptive Grammar to ascertain and record the grammatical forms and the conditions generally of a given linguistic community at a given time; to register, in fact, all the utterances of any individual belonging to such community which might fall from him without exposing him to the suspicion of being a foreigner. It will naturally register its observations in abstractions, such as paradigms and rules. Now, if we compare the abstractions made at any given period of a language with those made at another time, we find that the results are different, and we say that the language has changed in certain respects: nay, we may even be able to detect a certain regularity in these changes; as, for instance, if we note that in English every th in the third person singular present indicative of a verb is now replaced by s: but we gather by such comparisons no information as to the true nature and origin of these changes. Cause and effect do not and cannot exist between mere abstractions: they exist only between real objects and facts. It is only when we begin to take account of the psychical and bodily organisms on which language depends, and to seek for relations of cause and effect in connection with these, that we are on safe ground.

The true object of the Science of Language, as distinguished from Descriptive and Comparative Grammar, is the entirety of the utterances of all individuals that speak; and the relations of these utterances to each other. A full history of the development of language would demand an exact knowledge of all the groups of sound ever uttered or heard, and of all the ideas awakened by such sound-groups and symbolised by them. The impossibility of attaining to any such knowledge is obvious; it is, however, possible for us to get a general idea of the play of the forces at work in the vast and complex series of processes involved in the development of language. A part only of these operating forces is cognisable by our senses. Speaking and hearing are two of the processes which can be apprehended; and, again, the ideas, or pictures, called up by language, and those which, though unspoken, pass through our consciousness, are to some extent capable of cognition. But one of the greatest triumphs of modern psychology is the proof, due to its agency, of the unconscious activity of the human mind. All that has once been present to our consciousness remains as a working factor in unconsciousness. Power consciously acquired by exercise in consciousness may be translated into power operating and manifesting itself unconsciously. The mind forms from the groups of ideas with which it is stored, psychological groups, such as sound-groups, sequences of sounds, sequences of ideas, and syntactical combinations. Strong and weak verbs, derivatives from the same root, words fulfilling identical functions, such as the different parts of speech, associate themselves into groups; and again the plurals of nouns, their different cases, their different inflections, and even entire clauses of similar construction or similar cadence, group themselves in the same way. These groups arise naturally, automatically, and unconsciously, and must not be confused with the categories consciously drawn up by grammarians; though the two, of course, must frequently coincide.
