To the psychologist the individual is interesting primarily as a center of knowing, feeling, and willing. To the sociologist the individual begins to be interesting when he is thought as knowing, feeling, and willing something. In so far as a mere trick of emphasis may serve to distinguish problems, this ictus indicates the sociological starting-point. The individual given in experience is thought to the point at which he is available for sociological assumption, when he is recognized as a center of activities which make for something outside of the psychical series in which volition is a term. These activities must be referred primarily to desires, but the desires themselves may be further referred to certain universal interests. In this character the individual becomes one of the known or assumed terms of sociology. The individual as a center of active interests may be thought both as the lowest term in the social equation and as a composite term whose factors must be understood. These factors are either the more evident desires, or the more remote interests which the individual's desires in some way represent. At the same time, we must repeat the admission that these assumed interests are like the atom of physics. They are the metaphysical recourse of our minds in accounting for concrete facts. We have never seen or touched them. They are the hypothetical substratum of those regularities of conduct which the activities of individuals display.

We may start with the familiar popular expressions, "the farming interest," "the railroad interest," "the packing interest," "the milling interest," etc., etc. Everyone knows what the expressions mean. Our use of the term "interest" is not co-ordinate with these, but it may be approached by means of them. All the "interests" that are struggling for recognition in business and in politics are highly composite. The owner of a flour mill, for example, is a man before he is a miller. He becomes a miller at last because he is a man; i.e., because he has interests—in a deeper sense than that of the popular expressions—which impel him to act in order to gain satisfactions. The clue to all social activity is in this fact of individual interests. Every act that every man performs is to be traced back to an interest. We eat because there is a desire for food; but the desire is set in motion by a bodily interest in replacing exhausted force. We sleep because we are tired; but the weariness is a function of the bodily interest in rebuilding used-up tissue. We play because there is a bodily interest in use of the muscles. We study because there is a mental interest in satisfying curiosity. We mingle with our fellow-men because there is a mental interest in matching our personality against that of others. We go to market to supply an economic interest, and to war because of some social interest of whatever mixed or simple form.

With this introduction, we may venture an extremely abstract definition of our concept "interest." In general, an interest is an unsatisfied capacity, corresponding to an unrealized condition, and it is predisposition to such rearrangement as would tend to realize the indicated condition. Human needs and human wants are incidents in the series of events between the latent existence of human interest and the achievement of partial satisfaction. Human interests, then, are the ultimate terms of calculation in sociology. The whole life-process, so far as we know it, whether viewed in its individual or in its social phase, is at last the process of developing, adjusting, and satisfying interests.

No single term is of more constant use in recent sociology than this term "interests." We use it in the plural partly for the sake of distinguishing it from the same term in the sense which has become so familiar in modern pedagogy. The two uses of the term are closely related, but they are not precisely identical. The pedagogical emphasis is rather on the voluntary attitude toward a possible object of attention. The sociological emphasis is on attributes of persons which may be compared to the chemical affinities of different elements.

To distinguish the pedagogical from the sociological use of the term "interest," we may say pedagogically of a supposed case: "The boy has no interest in physical culture, or in shopwork, or in companionship with other boys, or in learning, or in art, or in morality." That is, attention and choice are essential elements of interest in the pedagogical sense. On the other hand, we may say of the same boy, in the sociological sense: "He has not discovered his health, wealth, sociability, knowledge, beauty, and rightness interests." We thus imply that interests, in the sociological sense, are not necessarily matters of attention and choice. They are affinities, latent in persons, pressing for satisfaction, whether the persons are conscious of them either generally or specifically, or not; they are indicated spheres of activity which persons enter into and occupy in the course of realizing their personality.

Accordingly, we have virtually said that interests are merely specifications in the make-up of the personal units. We have several times named the most general classes of interests which we find serviceable in sociology, viz.: health, wealth, sociability, knowledge, beauty, and rightness.

We need to emphasize, in addition, several considerations about these interests which are the motors of all individual and social action. First, there is a subjective and an objective aspect of them all. It would be easy to use terms of these interests in speculative arguments in such a way as to shift the sense fallaciously from the one aspect to the other; e.g., moral conduct, as an actual adjustment of the person in question with other persons, is that person's "interest," in the objective sense. On the other hand, we are obliged to think of something in the person himself impelling him, however unconsciously, toward that moral conduct, i.e., interest as "unsatisfied capacity" in the subjective sense. So with each of the other interests. The fact that these two senses of the term are always concerned must never be ignored; but, until we reach refinements of analysis which demand use for these discriminations, they may be left out of sight. Second, human interests pass more and more from the latent, subjective, unconscious state to the active, objective, conscious form. That is, before the baby is self-conscious, the baby's essential interest in bodily well-being is operating in performance of the organic functions. A little later the baby is old enough to understand that certain regulation of his diet, certain kinds of work or play, will help to make and keep him well and strong. Henceforth there is in him a co-operation of interest in the fundamental sense, and interest in the derived, secondary sense, involving attention and choice. If we could agree upon the use of terms, we might employ the word "desire" for this development of interest; i.e., physiological performance of function is, strictly speaking, the health interest; the desires which men actually pursue within the realm of bodily function may be normal or perverted, in an infinite scale of variety. So with each of the other interests. Third, with these qualifications provided for, resolution of human activities into pursuit of differentiated interests becomes the first clue to the combination that unlocks the mysteries of society. For our purposes in this argument we need not trouble ourselves very much about nice metaphysical distinctions between the aspects of interest, because we have mainly to do with interests in the same sense in which the man of affairs uses the term. The practical politician looks over the lobby at Washington and he classifies the elements that compose it. He says: "Here is the railroad interest, the sugar interest, the labor interest, the army interest, the canal interest, the Cuban interest, etc." He uses the term "interest" essentially in the sociological sense but in a relatively concrete form, and he has in mind little more than variations of the wealth interest. He would explain the legislation of a given session as the final balance between these conflicting pecuniary interests. He is right, in the main; and every social action is, in the same way, an accommodation of the various interests which are represented in the society concerned.

3. Social Pressures[162]

The phenomena of government are from start to finish phenomena of force. But force is an objectionable word. I prefer to use the word pressure instead of force, since it keeps the attention closely directed upon the groups themselves, instead of upon any mystical "realities" assumed to be underneath and supporting them, and since its connotation is not limited to the narrowly "physical." We frequently talk of "bringing pressure to bear" upon someone, and we can use the word here with but slight extension beyond this common meaning.

Pressure, as we shall use it, is always a group phenomenon. It indicates the push and resistance between groups. The balance of the group pressures is the existing state of society. Pressure is broad enough to include all forms of the group influence upon group, from battle and riot to abstract reasoning and sensitive morality. It takes up into itself "moral energy" and the finest discriminations of conscience as easily as bloodthirsty lust of power. It allows for humanitarian movements as easily as for political corruption. The tendencies to activity are pressures, as well as the more visible activities.
