Analysis of the Phenomena of the Human Mind

by James Mill

The Ideas which we have occasion to name, are first, Simple Ideas, the copies of simple sensations; secondly, Complex Ideas, the copies of several sensations, combined. Of those complex ideas, also, there is one species, those copied directly from sensations, in the formation of which the mind has exercised but little control; as the ideas of rose, horse, stone, and of what are called the objects of sense in general. There is another species of complex ideas which, though derived also from the senses, are put together in a great degree at our discretion, as the ideas of a 138 centaur, a mountain of gold, of comfort, of meanness; all that class of ideas in short which Mr. Locke has called mixed modes.

We may thus distinguish three classes of ideas, which we have occasion to name: 1, simple ideas, the copies of single sensations: 2, complex ideas, copied directly from sensations: 3, complex ideas, derived indeed from the senses, but put together in arbitrary combinations. The two former classes may be called Sensible, the last Mental Ideas.

With respect to ideas, of the first two classes, those which are the direct copies of our sensations, either singly, or in groups; it is of great importance to observe, and also to remember, that, for the most part, the words, which are employed as marks of the Sensations, are made to serve the further purpose of being marks also of the Ideas. The same word is at once the name of the sensations, and the ideas.

If any person were asked, whether the word BEING is the name of a Sensation, or of an Idea; he would immediately reply, that it is the name of an Idea. In like manner, if he were asked, whether the word ANIMAL is the mark of a cluster of Sensations, or of a cluster of Ideas; he would with equal readiness say, of a cluster of Ideas. But if we were to ask, whether the name Sheep is the name of a cluster of Sensations, or of a cluster of Ideas; he would probably say, that Sheep is the name of Sensations; in the same manner as rose, or apple. Yet, what is the difference? Only this, that ANIMAL is the more general name, and includes sheep along with other species; and that BEING is still more general, and includes animal along with vegetable, mineral, and other 139 genera. If sheep, therefore, or stone, be a name of sensations, so is animal or being; and if animal, or being, be a name of ideas, so is sheep or stone a name of ideas. The fact is, they are all names of both. They are names of the Sensations, primarily; but are afterwards employed as names also of the Ideas or copies of those sensations.

It thus appears, that the names generally of what are called the objects of sense are equivocal; and whereas it would have been a security against confusion to have been provided with appropriate names, one, in each instance, for the Sensation, and one for the Idea, the same name has been made to serve as the mark for both. The term horse is not only made to stand for the sensations of sight, of hearing, of touch, and even of smell, which give me occasion for the use of the term horse; but it stands also for the ideas of those sensations, as often as I have occasion to speak of that cluster of ideas which compose my notion of a horse. The term tree denotes undoubtedly the Idea in my mind, when I mean to convey the idea tree into the mind of another man; but it also stands for the sensations whence I have derived my idea of a tree.

Thus, too, if I mean to name my simple ideas; those, for example, of sight; I have no other names than red, blue, violet, &c.; but all these are names of the sensations. When forced to distinguish them, I must use the awkward expressions, my sensation of red, my idea of red. Again; sound of a trumpet, is the name, as well of the sensation, as the idea; flight of a bird, the name, as well of the sensation, as the idea; light the name as well of the sensation as the idea; pain 140 the name as well of the sensation as the idea; heat the name as well of the sensation as the idea.[43]

[⁴³] In strict propriety of language all these are names only of sensations, or clusters of sensations; not of ideas. A person studious of precision would not, I think, say heat, meaning the idea of heat, or a tree, when he meant the idea of a tree. He would use heat as the name only of the sensation of heat, and tree as the name of the outward object, or cluster of sensations; and if he had occasion to speak of the idea, he would say, my idea (or the idea) of heat; my idea (or the idea) of a tree.—Ed.

As we have remarked, in regard to SENSATIONS, singly, or in clusters, that they are too numerous to receive names but in classes, that is names common to every individual of a class, the same is obviously true of the IDEAS. The greater number of names of Sensible Ideas are names of classes: man is the name of a class; lion, horse, eagle, serpent, and so on, are names of classes.

Ideas, of the third class, those which the mind forms arbitrarily, are innumerable; because the combinations capable of being formed of the numerous elements which compose them, exceed computation. All these combinations cannot receive names. The memory can manage but a moderate number. Of possible combinations, therefore, a small proportion must be selected for naming. These, of course, are the combinations which are suggested by the occasions of life, and conduce to the ends which we pursue.

We arrange those ideas, also, in classes; to the end that every name may serve the purpose of marking, as extensively as possible. Thus the term fear is 141 applicable to a state of mind, of which the instances form a class. In like manner, courage is the name of a class; temperance, ignorance, piety, and so on, names of classes. Republic, aristocracy, monarchy, are names, each of them, not of an individual government, a government at one time and place, but of a class, a sort of government, at any time and place.
