denominate a multitude, by what originally was intended to express an individual.
It is this application of the name of an individual to a great multitude of objects, whose resemblance naturally recalls the idea of that individual, and of the name which expresses it, that seems originally to have given occasion to the formation of those classes and assortments, which, in the schools, are called genera and species, and of which the ingenious and eloquent M. Rousseau of Geneva finds himself so much at a loss to account for the origin. What constitutes a species is merely a number of objects, bearing a certain degree of resemblance to one another, and on that account denominated by a single appellation, which may be applied to express any one of them.
When the greater part of objects had thus been arranged under their proper classes and assortments, distinguished by such general names, it was impossible that the greater part of that almost infinite number of individuals, comprehended under each particular assortment or species, could have any peculiar or proper names of their own, distinct from the general name of the species. When there was occasion, therefore, to mention any particular object, it often became necessary to distinguish it from the other objects comprehended under the same general name, either, first, by its peculiar qualities; or, secondly, by the {307} peculiar relation which it stood in to some other things. Hence the necessary origin of two other sets of words, of which the one should express quality; the other, relation.
Nouns adjective are the words which express quality considered as qualifying, or, as the schoolmen say, in concrete with, some particular subject. Thus the word _green_ expresses a certain quality considered as qualifying, or as in concrete with, the particular subject to which it may be applied. Words of this kind, it is evident, may serve to distinguish particular objects from others comprehended under the same general appellation. The words _green tree_, for example, might serve to distinguish a particular tree from others that were withered or that were blasted.
Prepositions are the words which express relation considered, in the same manner, in concrete with the co-relative object. Thus the denote some relation subsisting between the objects expressed by the words between which the prepositions are placed; and they denote that this relation is considered in concrete with the co-relative object.
Words of this kind serve to distinguish particular objects from others of the same species, when those particular objects cannot be so properly marked out by any peculiar qualities of their own. When we say, _the green tree of the meadow_, for example, we distinguish a particular tree, not only by the quality which belongs to it, but by the relation which it stands in to another object.
As neither quality nor relation can exist in abstract, it is natural to suppose that the words which denote them considered in concrete, the way in which we always see them subsist, would be of much earlier invention than those which express them considered in abstract, the way in which we never see them subsist. The words _green_ and _blue_ would, in all probability, be sooner invented than the words _greenness_ and _blueness_; the words _above_ and _below_, than the words _superiority_ and _inferiority_. To invent words of the latter kind requires a much greater effort of abstraction than to invent those of the former. It is probable therefore, that such abstract terms would be of much later institution. Accordingly, their etymologies generally show that they are so, they being generally derived from others that are concrete.
But though the invention of nouns adjective be much more natural than that of the abstract nouns substantive derived from them, it would still, however, require a considerable degree of abstraction and generalization. Those, for example, who first invented the words _green_, _blue_, _red_, and the other names of colours, must have observed and compared together a great number of objects, must have remarked their resemblances and dissimilitudes in respect of the quality of colour, and must have arranged them, in their own minds, into different classes and assortments, according to those resemblances and {308} dissimilitudes. An adjective is by nature a general, and in some measure an abstract word, and necessarily pre-supposes the idea of a certain species or assortment of things, to all of which it is equally applicable. The word _green_ could not, as we were supposing might be the case of the word _cave_, have been originally the name of an individual, and afterwards have become, by what grammarians call an Antonomasia, the name of a species. The word _green_ denoting, not the name of a substance, but the peculiar quality of a substance, must from the very first have been a general word, and considered as equally applicable to any other substance possessed of the same quality. The man who first distinguished a particular object by the epithet of _green_, must have observed other objects that were not _green_, from which he meant to separate it by this appellation. The institution of this name, therefore, supposes comparison. It likewise supposes some degree of abstraction. The person who first invented this appellation must have distinguished the quality from the object to which it belonged, and must have conceived the object as capable of subsisting without the quality. The invention, therefore, even of the simplest nouns adjective must have required more metaphysics than we are apt to be aware of. The different mental operations, of arrangement or classing, of comparison, and of abstraction, must all have been employed, before even the names of the different colours, the least metaphysical of all nouns adjective, could be instituted. From all which I infer, that when languages were beginning to be formed, nouns adjective would by no means be the words of the earliest invention.
There is nothing expedient for denoting the different qualities of different substance, which as it requires no abstraction, nor any conceived separation of the quality from the subject, seems more natural than the invention of nouns adjective, and which, upon this account, could hardly fail, in the first formation of language, to be thought of before them. This expedient is to make some variation upon the noun substantive itself, according to the different qualities which it is endowed with. Thus in many languages, the qualities both of sex and of the want of sex are expressed by different terminations in the nouns substantive, which denote objects so qualified. In Latin, of male and female in the animals and persons to whom such appellations belong, without needing the addition of any adjective for this purpose. On the other hand, the words, _forum_, _pratum_, _plaustrum_, denote by their peculiar termination the total absence of sex in the different substances which they stand for. Both sex, and the want of all sex, being naturally considered as qualities modifying and inseparable from the particular substances to which they belong, it was natural to express them rather by a modification in the noun substantive, than by any general and abstract word {309} expressive of this particular species of quality. The expression bears, it is evident, in this way, a much more exact analogy to the idea or object which it denotes than in the other. The quality appears, in nature, as a modification of the substance, and as it is thus expressed in language, by a modification of the noun substantive, which denotes that substance, the quality and the subject are, in this case, blended together, if I may say so, in the expression, in the same manner as they appear to be in the object and in the idea. Hence the origin of the masculine, feminine, and neutral genders, in all the ancient languages. By means of these, the most important of all distinctions, that of substances into animated and inanimated, and that of animals into male and female, seem to have been sufficiently marked without the assistance of adjectives, or of any general names denoting this most extensive species of qualifications.
There are no more than these three genders in any of the languages with which I am acquainted; that is to say, the formation of nouns substantive can, by itself, and without the accompaniment of adjectives, express no other qualities but those three above mentioned, the qualities of male, of female, of neither male nor female. I should not, however, be surprised, if, in other languages with which I am unacquainted, the different formations of nouns substantive should be capable of expressing many other different qualities. The different diminutives of the Italian, and of some other languages, do, in reality, sometimes express a great variety of different modifications in the substances denoted by those nouns which undergo such variations.
It was impossible, however, that nouns substantive could, without losing altogether their original form, undergo so great a number of variations, as would be sufficient to express that almost infinite variety of qualities, by which it might, upon different occasions, be necessary to specify and distinguish them. Though the different formation of nouns substantive, therefore, might, for some time, forestall the necessity of inventing nouns adjective, it was impossible that this necessity could be forestalled altogether. When nouns adjective came to be invented, it was natural that they should be formed with some similarity to the substantives to which they were to serve as epithets or qualifications. Men would naturally give them the same terminations with the substantives to which they were first applied, and from that love of similarity of sound, from that delight in the returns of the same syllables, which is the foundation of analogy in all languages, they would be apt to vary the termination of the same adjective, according as they had occasion to apply it to a masculine, to a feminine, or to a neutral substantive. They would say, This variation, in the termination of the noun adjective, according to {310} the gender of the substantive, which takes place in all the ancient languages, seems to have been introduced chiefly for the sake of a certain similarity of sound, of a certain species of rhyme, which is naturally so very agreeable to the human ear. Gender, it is to observed, cannot properly belong to a noun adjective, the signification of which is always precisely the same, to whatever species of substantives it is applied. When we say, _a great man_, _a great woman_, the word _great_ has precisely the same meaning in both cases, and the difference of the sex in the subjects to which it may be applied, makes no sort of difference in its signification.
_Magnus_, _magna_, _magnum_, in the same manner, are words which express precisely the same quality, and the change of the termination is accompanied with no sort of variation in the meaning. Sex and gender are qualities which belong to substances, but cannot belong to the qualities of substances. In general, no quality, when considered in concrete, or as qualifying some particular subject, can itself be conceived as the subject of any other quality; though when considered in abstract it may. No adjective therefore can qualify any other adjective. A _great good man_, means a man who is both _great_ and _good_. Both the adjectives qualify the substantive; they do not qualify one another. On the other hand, when we say, the _great goodness_ of the man, the word _goodness_ denoting a quality considered in abstract, which may itself be the subject of other qualities, is upon that account capable of being qualified by the word _great_.
If the original invention of nouns adjective would be attended with so much difficulty, that of prepositions would be accompanied with yet more. Every preposition, as I have already observed, denotes some relation considered in concrete with the co-relative object. The preposition _above_, for example, denotes the relation of superiority, not in abstract, as it is expressed by the word _superiority_, but in concrete with some co-relative object. In this phrase, for example, _the tree above the cave_, the word _above_ expresses a certain relation between the _tree_ and the _cave_, and it expresses this relation in concrete with the co-relative object, _the cave_. A preposition always requires, in order to complete the sense, some other word to come after it; as may be observed in this particular instance. Now, I say, the original invention of such words would require a yet greater effort of abstraction and generalization, than that of nouns adjective. First of all, the relation is, in itself, a more metaphysical object than a quality. Nobody can be at a loss to explain what is meant by a quality; but few people will find themselves able to express, very distinctly, what is understood by a relation. Qualities are almost always the objects of our external senses; relations never are. No wonder therefore, that the one set of objects should be so much more comprehensible than the other.
Secondly, though prepositions always express the relation which they stand for, in concrete with the co-relative object, they could not have {311} originally been formed without a considerable effort of abstraction. A preposition denotes a relation, and nothing but a relation. But before men could institute a word, which signified a relation, and nothing but a relation, they must have been able, in some measure, to consider this relation abstractedly from the related objects; since the idea of those objects does not, in any respect, enter into the signification of the preposition. The invention of such a word, therefore, must have required a considerable degree of abstraction. Thirdly, a preposition is from its nature a general word, which, from its very first institution, must have been considered as equally applicable to denote any other similar relation. The man who first invented the word _above_, must not only have distinguished, in some measure, the relation of _superiority_ from the objects which were so related, but he must also have distinguished this relation from other relations, such as, from the relation of _inferiority_ denoted by the word _below_, from the relation of _juxta-position_, expressed by the word _beside_, and the like. He must have conceived this word, therefore, as expressive of a particular sort or species of relation distinct from every other, which could not be done without a considerable effort of comparison and generalization.
Whatever were the difficulties, therefore, which embarrassed the first invention of nouns adjective, the same, and many more, must have embarrassed that of prepositions. If mankind, therefore, in the first formation of languages, seem to have, for some time, evaded the necessity of nouns adjective, by varying the termination of the names of substances, according as these varied in some of their most important qualities, they would much more find themselves under the necessity of evading, by some similar contrivance, the yet more difficult invention of prepositions. The different cases in the ancient languages is a contrivance of precisely the same kind. The genitive and dative cases, in Greek and Latin, evidently supply the place of the prepositions; and by a variation in the noun substantive, which stands for the co-relative term, express the relation which subsists between what is denoted by that noun substantive, and what is expressed by some other word in the sentence. In these expressions, for example, _fructus arboris_, _the fruit of the tree_; _sacer Herculi_, _sacred to Hercules_; the variations made in the co-relative words, arbor and Hercules, express the same relations which are expressed in English by the prepositions _of_ and _to_.
To express a relation in this manner, did not require any effort of abstraction. It was not here expressed by a peculiar word denoting relation and nothing but relation, but by a variation upon the co-relative term. It was expressed here, as it appears in nature, not as something separated and detached, but as thoroughly mixed and blended with the co-relative object.
To express relation in this manner, did not require any effort of generalization. The words _arboris_ and _Herculi_, while they involve in {312} their signification the same relation expressed by the English prepositions _of_ and _to_, are not, like those prepositions, general words, which can be applied to express the same relation between whatever other objects it might be observed to subsist.
To express relation in this manner did not require any effort of comparison. The words _arboris_ and _Herculi_ are not general words intended to denote a particular species of relations which the inventors of those expressions meant, in consequence of some sort of comparison, to separate and distinguish from every other sort of relation. The example, indeed, of this contrivance would soon probably be followed, and whoever had occasion to express a similar relation between any other objects would be very apt to do it by making a similar variation on the name of the co-relative object. This, I say, would probably, or rather certainly happen; but it would happen without any intention or foresight in those who first set the example, and who never meant to establish any general rule. The general rule would establish itself insensibly, and by slow degrees, in consequence of that love of analogy and similarity of sound, which is the foundation of by far the greater part of the rules of grammar.
To express relation, therefore, by a variation in the name of the co-relative object, requiring neither abstraction, nor generalization, nor comparison of any kind, would, at first, be much more natural and easy, than to express it by those general words called prepositions, of of which the first invention must have demanded some degree of all those operations.
The number of cases is different in different languages. There are five in the Greek, six in the Latin, and there are said to be ten in the Armenian language. It must have naturally happened that there should be a greater or a smaller number of cases, according as in the terminations of nouns substantive the first formers of any language happened to have established a greater or a smaller number of variations, in order to express the different relations they had occasion to take notice of, before the invention of those more general and abstract prepositions which could supply their place.
It is, perhaps, worth while to observe that those prepositions, which in modern languages hold the place of the ancient cases, are, of all others, the most general, and abstract, and metaphysical; and of consequence, would probably be the last invented. Ask any man of common acuteness, What relation is expressed by the preposition _above_? He will readily answer, that of _superiority_. By the preposition _below_? He will as quickly reply that of _inferiority_.
But ask him, what relation is expressed by the preposition _of_, and, if he has not beforehand employed his thoughts a good deal upon these subjects, you may safely allow him a week to consider of his answer.
The prepositions _above_ and _below_ do not denote any of the relations expressed by the cases in the {313} ancient languages. But the preposition _of_, denotes the same relation, which is in them expressed by the genitive case; and which, it is easy to observe, is of a very metaphysical nature. The preposition _of_, denotes relation in general, considered in concrete with the co-relative object. It marks that the noun substantive which goes before it, is somehow or other related to that which comes after it, but without in any respect ascertaining, as is done by the preposition _above_, what is the peculiar nature of that relation. We often apply it, therefore, to express the most opposite relations; because, the most opposite relations agree so far that each of them comprehends in it the general idea or nature of a relation. We say, _the father of the son_, and _the son of the father_; _the fir-trees of the forest_, and _the forest of the fir-trees_. The relation in which the father stands to the son is, it is evident, a quite opposite relation to that in which the son stands to the father; that in which the parts stand to the whole, is quite opposite to that in which the whole stands to the parts. The word _of_, however, serves very well to denote all those relations, because in itself it denotes no particular relation, but only relation in general; and so far as any particular relation is collected from such expressions, it is inferred by the mind, not from the preposition itself, but from the nature and arrangement of the substantives, between which the preposition is placed.
What I have said concerning the preposition _of_, may in some measure be applied to the prepositions _to_, _for_, _with_, _by_, and to whatever other prepositions are made use of in modern languages, to supply the place of the ancient cases. They all of them express very abstract and metaphysical relations, which any man, who takes the trouble to try it, will find it extremely difficult to express by nouns substantive, in the same manner as we may express the relation denoted by the preposition _above_, by the noun substantive _superiority_. They all of them, however, express some specific relation, and are, consequently, none of them so abstract as the preposition _of_, which may be regarded as by far the most metaphysical of all prepositions. The prepositions, therefore, which are capable of supplying the place of the ancient cases, being more abstract than the other prepositions, would naturally be of more difficult invention. The relations at the same time which those prepositions express, are, of all others, those which we have most frequent occasion to mention. The prepositions _above_, _below_, _near_, _within_, _without_, _against_, &c., are much more rarely made use of, in modern languages, than the prepositions _of_, _to_, _for_, _with_, _from_, _by_. A preposition of the former kind will not occur twice in a page; we can scarce compose a single sentence without the assistance of one or two of the latter. If these latter prepositions, therefore, which supply the place of the cases, would be of such difficult invention on account of their abstractedness, some expedient to supply their place must have been of indispensable necessity, on account of the frequent occasion {314} which men have to take notice of the relations which they denote. But there is no expedient so obvious, as that of varying the termination of one of the principal words.
It is, perhaps, unnecessary to observe, that there are some of the cases in the ancient languages, which, for particular reasons, cannot be represented by any prepositions. These are the nominative, accusative, and vocative cases. In those modern languages, which do not admit of any such variety in the terminations of their nouns substantive, the correspondent relations are expressed by the place of the words, and by the order and construction of the sentence.
As men have frequently occasion to make mention of multitudes as well as of single objects, it became necessary that they should have some method of expressing number. Number may be expressed either by a particular word, expressing number in general, such as the words _many_, _more_, &c., or by some variation upon the words which express the things numbered. It is this last expedient which mankind would probably have recourse to, in the infancy of language. Number, considered in general, without relation to any particular set of objects numbered, is one of the most abstract and metaphysical ideas, which the mind of man is capable of forming; and, consequently, is not an idea, which would readily occur to rude mortals, who were just beginning to form a language. They would naturally, therefore, distinguish when they talked of a single, and when they talked of a multitude of objects, not by any metaphysical adjectives, such as the English _a_, _an_, _many_, but by a variation upon the termination of the word which signified the objects numbered. Hence the origin of the singular and plural numbers, in all the ancient languages; and the same distinction has likewise been retained in all the modern languages, at least, in the greater part of the words.
All primitive and uncompounded languages seem to have a dual, as well as a plural number. This is the case of the Greek, and I am told of the Hebrew, of the Gothic, and of many other languages. In the rude beginnings of society, _one_, _two_, and _more_, might possibly be all the numeral distinctions which mankind would have any occasion to take notice of. These they would find it more natural to express, by a variation upon every particular noun substantive, than by such general and abstract words as _one_, _two_, _three_, _four_, &c. These words, though custom has rendered them familiar to us, express, perhaps, the most subtile and refined abstractions, which the mind of man is capable of forming. Let any one consider within himself, for example, what he means by the word _three_, which signifies neither three shillings, nor three pence, nor three men, nor three horses, but three in general; and he will easily satisfy himself that a word, which denotes so very metaphysical an abstraction, could not be either a very obvious or a very early invention. I have read of some savage nations, whose language {315} was capable of expressing no more than the three first numeral distinctions. But whether it expressed those distinctions by three general words, or by variations upon the nouns substantive, denoting the things numbered, I do not remember to have met with any thing which could clearly determine.
As all the same relations which subsist between single, may likewise subsist between numerous objects, it is evident there would be occasion for the same number of cases in the dual and in the plural, as in the singular number. Hence the intricacy and complexness of the declensions in all the ancient languages. In the Greek there are five cases in each of the three numbers, consequently fifteen in all.
As nouns adjective, in the ancient languages, varied their terminations according to the gender of the substantive to which they were applied, so did they likewise according to the case and the number. Every noun adjective in the Greek language, therefore, having three genders, and three numbers, and five cases in each number, may be considered as having five and forty different variations. The first formers of language seem to have varied the termination of the adjective, according to the case and the number of the substantive, for the same reason which made them vary it according to the gender; the love of analogy, and of a certain regularity of sound. In the signification of adjectives there is neither case nor number, and the meaning of such words is always precisely the same, notwithstanding all the variety of termination under which they appear. _Magnus vir_, great men_; in all these expressions the words, _magnus_, _magni_, _magnorum_, as well as the word _great_, have precisely one and the same signification, though the substantives to which they are applied have not. The difference of termination in the noun adjective is accompanied with no sort of difference in the meaning. An adjective denotes the qualification of a noun substantive. But the different relations in which that noun substantive may occasionally stand, can make no sort of difference upon its qualification. If the declensions of the ancient languages are so very complex, their conjugations are infinitely more so. And the complexness of the one is founded upon the same principle with that of the other, the difficulty of forming, in the beginnings of language, abstract and general terms.
Verbs must necessarily have been coëval with the very first attempts towards the formation of language. No affirmation can be expressed without the assistance of some verb. We never speak but in order to express our opinion that something either is or is not. But the word denoting this event, or this matter of fact, which is the subject of our affirmation, must always be a verb.
Impersonal verbs, which express in one word a complete event, which preserve in the expression that perfect simplicity and unity, {316} which there always is in the object and in the idea, and which suppose no abstraction, or metaphysical division of the event into its several constituent members of subject and attribute, would, in all probability, be the species of verbs first invented. The verbs them express a complete affirmation, the whole of an event, with that perfect simplicity and unity with which the mind conceives it in nature. On the contrary, the phrases, _Alexander ambulat_, _Alexander walks_; _Petrus sedet_, _Peter sits_, divide the event, as it were, into two parts, the person or subject, and the attribute, or matter of fact, affirmed of that subject. But in nature, the idea or conception of Alexander walking, is as perfectly and completely one simple conception, as that of Alexander not walking. The division of this event, therefore, into two parts, is altogether artificial, and is the effect of the imperfection of language, which, upon this, as upon many other occasions, supplies, by a number of words, the want of one, which could express at once the whole matter of fact that was meant to be affirmed. Every body must observe how much more simplicity there is in the natural expression, _pluit_, than in the more artificial pluvia_, _the weather is rainy_. In these two last expressions, the simple event, or matter of fact, is artificially split and divided in the one, into two; in the other, into three parts. In each of them it is expressed by a sort of grammatical circumlocution, of which the significancy is founded upon a certain metaphysical analysis of the component parts of the idea expressed by the word _pluit_. The first verbs, therefore, perhaps even the first words, made use of in the beginnings of language, would in all probability be such impersonal verbs. It is observed accordingly, I am told, by the Hebrew grammarians, that the radical words of their language, from which all the others are derived, are all of them verbs, and impersonal verbs.
It is easy to conceive how, in the progress of language, those impersonal verbs should become personal. Let us suppose, for example, that the word _venit_, _it comes_, was originally an impersonal verb, and that it denoted, not the coming of something in general, as at present, but the coming of a particular object, such as _the lion_.
The first savage inventors of language, we shall suppose, when they observed the approach of this terrible animal, were accustomed to cry out to one another, _venit_, that is, _the lion comes_; and that this word thus expressed a complete event, without the assistance of any other. Afterwards, when, on the further progress of language, they had begun to give names to particular substances, whenever they observed the approach of any other terrible object, they would naturally join the name of that object to the word _venit_, and cry out, _venit ursus_, _venit lupus_. By degrees the word venit would thus come to signify the coming of any {317} terrible object, and not merely the coming of the lion. It would, now, therefore, express, not the coming of a particular object, but the coming of an object of a particular kind. Having become more general in its signification, it could no longer represent any particular distinct event by itself, and without the assistance of a noun substantive, which might serve to ascertain and determine its signification. It would now, therefore, have become a personal, instead of an impersonal verb. We may easily conceive how, in the further progress of society, it might still grow more general in its signification, and come to signify, as at present, the approach of any thing whatever, whether it were good, bad, or indifferent.
It is probably in some such manner as this, that almost all verbs have become personal, and that mankind have learned by degrees to split and divide almost every event into a great number of metaphysical parts, expressed by the different parts of speech, variously combined in the different members of every phrase and sentence.[1] The same sort of progress seems to have been made in the art of speaking as in the art of writing. When mankind first began to attempt to express their ideas by writing, every character represented a whole word. But the number of words being almost infinite, the memory found itself quite loaded and oppressed by the multitude of characters which it was obliged to retain. Necessity taught them, therefore, to divide words into their elements, and to invent characters which should represent, not the words themselves, but the elements of which they were composed. In consequence of this invention, every particular word came to be represented, not by one character, but by a multitude of characters; and the expression of it in writing became much more intricate and complex than before. But though particular words were thus represented by a greater number of characters, the whole language was expressed by a much smaller, and about four and twenty letters were found capable of supplying the place of that immense multitude of characters, which were requisite before. In the same manner, in the beginnings of language, men seem to have attempted to express every particular event, which they had occasion to take notice of, by a particular word, which expressed at once the whole of that event. But as the number of words must, in this case, have become really infinite in consequence of the really infinite variety of events, men found themselves partly compelled by necessity, and partly conducted by nature, to divide {318} every event into what may be called its metaphysical elements, and to institute words, which should denote not so much the events, as the elements of which they were composed. The expression of every particular event, became in this manner more intricate and complex, but the whole system of the language became
