As an individual his primary interest is in self, but he finds by experience that he cannot be independent of others. His impulses, his feelings, and his ideas are due to the relations that he has with that which is outside of himself. He may exercise choice, but it is within the limits set by these outside relations. He may make use of what they can do for him or he may antagonize them, at least he cannot ignore them. Experience determines how the individual may best adapt himself to his environment and adapt the environment to his own needs, and he thus establishes certain definite relationships. Any group of individuals, who have thus consciously established relationships with one another and with their social environment is a society. The relations through whose channels the interplay of social forces is constantly going on make up the social organization. The readjustments of these relations for the better adaptation of one individual to another, or of either to their environment, make up the process of social development. A society which remains in equilibrium is termed static, that which is changing is called dynamic.

2. The Field and the Purpose of Sociology.—Life in society is the subject matter of sociological study. Sociology is concerned with the origin and development of that life, with its present forms and activities, and with their future development. It finds its material in the every-day experiences of men, women, and children in whatever stage of progress they may be; but for practical purposes its chief interest is in the normal life of civilized communities, together with the past developments and future prospects of that life. The purpose of sociological study is to discover the active workings and controlling principles of life, its essential meaning, and its ultimate goal; then to apply the principles, laws, and ideals discovered to the imperfect social process that is now going on in the hope of social betterment.

3. Source Material for Study.—The source material of social life lies all about us. For its past history we must explore the primitive conduct of human beings as we learn it from anthropology and archæology, or as we infer it from the lowest human races or from animal groups that bear the nearest physical and mental resemblance to mankind. For present phenomena we have only to look about us, and having seen to attempt their interpretation. Life is mirrored in the daily press. Pick up any newspaper and examine its contents. It reveals social characteristics both local and wide-spread.

4. Social Characteristics—Activity.—The first fact that stands out clearly as a characteristic of social life is activity. Everybody seems to be doing something. There are a few among the population, like vagrants and the idle rich, who are parasites, but even they sustain relations to others that require a certain sort of effort. Activity seems fundamental. It needs but a hasty survey to show how general it is. Farmers are cultivating their broad acres, woodsmen are chopping and hewing in the forest, miners are drilling in underground chambers, and the products of farm, forest, and mine are finding their way by river, road, and rail to the great distributing centres. In the town the machinery of mill and factory keeps busy thousands of operatives, and turns out manufactured products to compete with the products of the soil for right of way to the cities of the New World and the Old. Busiest of all are the throngs that thread the streets of the great centres, and pour in and out of stores and offices. Men rush from one person to another, and interview one after another the business houses with which they maintain connection; women swarm about the counters of the department stores and find at the same time social satisfaction and pecuniary reward; children in hundreds pour into the intellectual hopper of the schoolroom and from there to the playground. Everybody is busy, and everybody is seeking personal profit and satisfaction.

5. Mental Activity.—There is another kind of activity of which these economic and social phases are only the outward expression, an activity of the mind which is busy continually adjusting the needs of the individual or social organism and the environment to each other. Some acts are so instinctive or habitual that they do not require conscious mental effort; others are the result of reasoning as to this or that course of action. The impulse of the farmer may be to remain inactive, or the schoolboy may feel like going fishing; the call of nature stimulates the desire; but reason reaches out and takes control and directs outward activity into proper channels. On the other hand, reason fortifies worthy inclinations. The youth feels an inclination to stretch his muscles or to use his brains, and reason re-enforces feeling. The physical need of food, clothing, and shelter acts as a goad to drive a man to work, and reason sanctions his natural response. This mental activity guides not only individual human conduct but also that of the group. Instinct impels the man to defend his family from hardship or his clan from defeat, and reason confirms the impulse. His sociable disposition urges him to co-operate in industry, and reason sanctions his inclination. The history of society reveals an increasing influence of the intellect in thus directing instinct and feeling. It is a law of social activity that it tends to become more rational with the increase of education and experience. But it is never possible to determine the quantitative influence of the various factors that enter into a decision, or to estimate the relative pressure of the forces that urge to activity. Alike in mental and in physical activity there is a union of all the causative factors. In an act of the will impulse, feeling, and reflection all have their part; in physical activity it is difficult to determine how compelling is any one of the various forces, such as heredity and environment, that enter into the decision.

6. The Valuation of Social Activities.—The importance to society of all these activities is not to be measured by their scope or by their vigor or volume, but by the efficiency with which they perform their function, and the value of the end they serve. Domestic activities, such as the care of children, may be restricted to the home, and a woman's career may seem to be blighted thereby, but no more important work can be accomplished than the proper training of the child. Political activity may be national in scope, but if it is vitiated by corrupt practices its value is greatly diminished. Certain activities carry with them no important results, because they have no definite function, but are sporadic and temporary, like the coming together of groups in the city streets, mingling in momentary excitement and dissolving as quickly.

The true valuation of activities is to be determined by their social utility. The employment of working men in the brewing of beer or the manufacture of chewing-gum may give large returns to an individual or a corporation, but the social utility of such activity is small. Business enterprise is naturally self-centred; the first interest of every individual or group is self-preservation, and business must pay for itself and produce a surplus for its owner or it is not worth continuing from the economic standpoint; but a business enterprise has no right selfishly to disregard the interests of its employees and of the public. Its social value must be reckoned as small or great, not by the amount of business carried on, but by its contribution to human welfare.

Take a department store as an illustration. It may be highly profitable to its owners, giving large returns on the investment, while distributing cheap and defective goods and paying its employees less than a decent living wage. Its value is to be determined as small because its social utility is of little worth. When the value of activity is estimated on this basis, it will be seen that among the noblest activities are those of the philanthropist who gives his time and interest without stint to the welfare of other folk; of the minister who lends himself to spiritual ministry, and the physician who gives up his own comfort and sometimes his own life to save those who are physically ill; of the housewife who bears and rears children and keeps the home as her willing contribution to the life of the world; and of the nurses, companions, and teachers who are mothers, sisters, and wives to those who need their help.

7. Results of Activity.—The product of activity is achievement. The workers of the world are continually transforming energy into material products. To clear away a forest, to raise a thousand bushels of grain, to market a herd of cattle or a car-load of shoes, to build a sky-scraper or an ocean liner, is an achievement. But it is a greater achievement to take a child mind and educate it until it learns how to cultivate the soil profitably, how to make a machine or a building of practical value, and how to save and enrich life.

The history of human folk shows that achievement has been gradual, and much of it without conscious planning, but the great inventors, the great architects, the great statesmen have been men of vision, and definite purpose is sure to fill a larger place in the story of achievement. Purposive progress rather than unconscious, telic rather than genetic, is the order of the evolution of society.
