I believe I have shown with sufficient clearness that a language may have a great diversity of apparent forms, and may express all grammatical relations with definiteness, and yet when taken as a whole it may lack true grammatical form. From this arises an essential and real graduated difference between languages. This difference, however, has nothing to do with the question whether particular languages employ exclusively agglutination or inflection, as all began with agglutination; but in the languages of the higher class, it became in its effects on the mind, identical with inflection.
As languages of the higher class, one has but to name the cultivated idioms of Asia and Europe, Sanscrit, Greek and Latin, in order to apply to them the above statement. It is still more necessary, however, to understand thoroughly the structure of those languages which are on a lower plane, partly because this will convince us of the correctness of the classification, partly because these tongues are less generally known.
It is enough to take up some single leading grammatical relation. I select for this purpose the verb as the most important part of speech, with which most of the others come into relation, and which completes the formation of the sentence, the grammatical purpose of all language—and often embraces it wholly in itself. But I shall confine myself solely to that which makes the verb a verb, the characteristic notation of its peculiar verbal nature. In every language this point is the most important and the most difficult, and cannot be made too clear to throw light upon the whole of the language. Linguistic character can be ascertained through this point in the shortest and most certain manner.
The verb is the union of the subject and predicate of the sentence by means of the notion of Being; yet not of every predicate. The attribute which is united to the substance by the verb must be an energic one, a participial. The substance is represented in the verb as in motion, as connecting the Being with the energic attribute. By means of this representation, and the peculiar nature of the attribute, the verb is distinguished from the mere logical copula, with which it is liable to be confounded if these ideas are not understood. If the verb is explained merely as a synthesis of Being with any other attribute, then the origin of the tenses cannot be wholly derived from one idea, for the idea of time alone would allow only a three-fold distinction. Moreover, in such case the true and efficient nature of the verb is misunderstood. In the sentence, “The man is good,” the verb is not a synthesis of the adjective “good” with the substantive, but it is a participial of the energic attribute “to be good,” which contains a condition, having beginning, middle and end, and consequently resembles an action. Fully analyzed, the sentence would be, “He is being good.” Where the substantive verb stands without a visible predicate, as in the sentence, “I am,” then the verb “to be” has itself as the object of a synthesis, “I am being.” But as rude nations would find this difficult to comprehend, the verb “to be” is either entirely lacking, as in many American languages, or else it has an original material sense, and is confounded with “to stand,” “to give,” “to eat,” etc., and thus indicates Being as identical with the most familiar occupations.
The subject, the substance represented as in action, may be one independent of the speakers, or it may be identical with one of them, and this identity is expressed by the pronouns. From this arises the persons. The energic attribute may exert its action in various manners in the substance or between two substances; this gives rise to the forms or classes of verbs. Their action must be confined to a given point or period of time. The Being may be understood as definite or indefinite, etc., and in this is the origin of modes. Being is inseparably connected with the notation of time. This, united with the fixation of the point or period of time of an action, forms the tenses. No verb, therefore, can be conceived as without persons and tenses, modes and classes; yet these qualities do not constitute its essence, but arise from the latter, which itself is the synthesis brought about by the notion of Being. The signs of these qualities must be made to appear in the grammatical notation of the verb, but in such a manner that they appear dependent on its nature, making one with it.
The energic attribute, which aids in forming the verb, may be a real movement or action, as going, coming, living, working, etc., or merely a qualitative Being, as a being beautiful, good, mortal, or immortal. In the former case, we have a real attributive verb, in the latter a substantive verb, in which an attribute is considered as at rest, hence as an adjective. Although in both cases the nature of the verb is the same, yet in many languages this difference leads to a corresponding variety in grammatical notation.
In accordance with these ideas culled from universal grammar, the forms of the conjugations in the various languages will now be considered.
I have taken as a basis for this investigation as many American languages as I thought sufficient for the purpose, and as would not make the survey oppressive by their number; but as I do not name all of them, and pay still less attention to pointing out in what other groups of languages the peculiarities named occur, it must be understood that what is here said is not intended as a characterization of American languages. This is reserved for another study.
In order to judge how closely these languages approach grammatical perfection in this point, we must take as our criterion that condition of speech where there is a class of words, which possess verbal power, and are at the same time separated by a definite form from all other parts of speech. With reference to this condition as the highest, we must arrange in various grades all other structural forms or paraphrases of the verb.
The notion of Being, which constitutes the basis and the essence of the verb, can be indicated either,
