NOUNS ADJECTIVE.

As the purpose of language is to denote sensations and ideas; to mark them for our own use, or to give indication of them to our fellow men; it is obvious that the names of sensations and ideas are the fundamental parts of language. But as ideas are very numerous, and the limits of the human memory admit the use of only a limited number of marks or names, various contrivances are employed to make one name serve as many purposes as possible.

Of the contrivances for making the use of each word as extensive as possible, we have already adverted to one of great importance; that of arranging ideas in classes, and making one name stand for each individual of the class. When the classes are large, one word or mark serves to name or indicate many individuals.

But when, for the sake of economizing names, those classes have been made as large as possible, we often find occasion for breaking them down into smaller parcels, or sub-classes, and speaking of these sub-classes by themselves.

An example will render what is here expressed sufficiently plain. The term sound, is the name of a large class of ideas or sensations; for it is equally the name of both; the sound of thunder, the sound of a cannon, the whistling of the wind, the voice of a man, the howling of a dog, and so on.

Among these sounds I perceive differences; some affect me in one way, and I wish to mark them as doing so; some affect me in another way, and I wish to mark them as affecting me in that particular way.

It is obvious that names might be invented for these subordinate classes, to mark such of them as we have occasion to mark; and the cases are numerous, in which this is the expedient adopted. Thus the term animal is the name of a large class. But we have occasion to speak apart of various portions of this class, to all the more important of which portions, we have given particular names. Horse is the name of one portion, man of another, sheep of another, and so of the rest.

There is, however, another mode of naming subordinate classes; a mode by which the use of names is greatly economized, and of which the utility is therefore conspicuous.

The subordinate class is distinguished from they rest of the greater class by some peculiarity, something in which the individuals of it agree with one another, and do not agree with the rest. Thus to recur to the example of sound. One set of sounds affect me in a certain way, a way peculiar to that set. Wishing to distinguish these sounds from others by a mark, I call them loud. Another set of sounds affect me in another way, and I call them low; a third set in another way, and I call them harsh; a fourth in another way, and I call them sweet. By means of those adjectives applied as marks upon the mark of the great class, I have the names of four species, or sub-classes; 1, loud sounds; 2, low sounds; 3, harsh sounds; 4, sweet sounds; and the number might be greatly enlarged.

It thus appears that, as nouns substantive are marks of ideas, or sensations, nouns adjective are marks put upon nouns substantive, or marks upon marks; in order to limit the signification of the noun substantive; and instead of its marking a large class, to make it mark a subdivision of that class. Thus the word, rose, is the mark of a large class: apply to it the adjective yellow, that is, put the mark yellow upon the mark rose, and you have the name, yellow rose, which is a sub-division, or species, of the class Rose.

This peculiarity of naming, this putting of marks upon marks, in order to modify the meaning of a certain mark, is a contrivance which deserves the greatest attention. It is one of the principal expedients for the great purpose of economizing names, and performing the business of marking with the smallest number of marks; but, like the rest of the contrivances for this purpose, it contributes to obscure the simple process of naming; and when not distinctly known and attended to, operates as a source of confusion and error.

The use of adjectives, in economizing names, is most conspicuous, in the case of those subdivisions which apply to the greatest number of classes. There is one distinction which applies to most classes; the distinction between what pleases, and what does not please us, no matter on what account. The first we call good, the second evil. These two terms serve to mark a very great number of subordinate classes, and, of course, save, to a great extent, the multiplication of names.

Thus, in the case of the senses, we have the word taste, the mark of one great class of sensations. Tastes we divide into sub-classes by the words good and evil; good tastes being one class, bad tastes another. If we had invented separate marks for each of these two classes, we should have had three names, to mark the class taste with these its two primary subdivisions; and we should have had occasion for the same number of names in the case of each of the five senses; or, fifteen different names. But the adjectives, good, and evil, they being applicable to all the senses, save us the invention of names for the sub-classes of the other four senses; as we say good smells, bad smells, in the same manner as good tastes, and bad tastes. They save, therefore, eight names out of fifteen, or more than one-half.

The economizing power of adjectives is still more remarkable, when we depart from simple sensations and ideas, and apply them as marks upon the names of the complex, which are far more numerous. Thus, the term horse is the mark of a complex idea, and the name of a class of objects. We say good horse and bad horse, good dog and bad dog, good house and bad house, and so in cases without number; in each of which, the repetition of the two adjectives, good, and bad, saves us the use and embarrassment of separate names.

It deserves to be remarked, that the terms good and evil apply much more generally to that class of complex ideas, in the formation of which the mind has but little control; namely, those of external objects; than they do to the other class of complex ideas which the mind makes up in an arbitrary manner to suit its own convenience. Ideas of the latter description are very often made up according to the distinction of good and evil. Thus, the idea glory, is composed of ingredients all of which belong to the classes, good; and the idea good, is multifariously included in the name. After the same manner, the idea of evil is multifariously included in the complex idea disgrace. Good is implied in the term virtue, evil in the term vice; good is implied in the term wealth, evil in the term poverty; good is implied in the term power, evil in the term weakness. In some cases, the ideas of this class are so general, that good and evil are both included; and, in such cases, adjectives are necessary to mark the subdivisions or species. Thus, we say good manners, bad manners; good sense, bad sense; good conduct, bad conduct; and so on.

Next to the adjectives which form the numerous sub-classes of good and evil, those which mark degrees are of the most extensive application, and in the operation of sub-marking save the greatest number of names. Thus the terms, great, and little, are applicable to a great proportion of the marks of complex ideas of both formations. We say a great tree, a little tree; a great man, a little man; a great crime, a small crime; great blame, little blame; great honour, little honour; great value, little value; great weight, little weight; great strength, little strength, and so on.

Different adjectives differ in the number of classes to the subdivision of which they are subservient. Thus hot and cold are only applicable where diversities of temperature are included; round, square, and so on, where figure is included; white or black, where colour; and so on.

Beside the use of adjectives, in dividing great classes into smaller ones, without multiplication of names; they sometimes answer another purpose. It often happens that, in the cluster of sensations or ideas which have one name; we have occasion to call attention particularly to some one ingredient of the cluster. Adjectives render this service, as well as that of marking a class. This rose, I say, is red; that rose is yellow: this stone is hot, that stone is cold. The term, red rose, or yellow rose, is the name of a class. But when I say, this rose is red, where an individual is named, I mark emphatically the specific difference; namely, red, or yellow; which constitutes that subdivision of the genus rose, to which the individual belongs.45
