Economics contrasted with the natural sciences
1. Political economy, as one of the social sciences, may be contrasted with the natural sciences, which deal with material things and their mutual relations, while it deals with one aspect of men's life in society, namely, the earning of a living, or the use of wealth. It is true that political economy also has to do with plants and animals and the earth—in fact, with all of those things which are the subject-matter of the natural sciences; but it has to do with them only in so far as they are related to man's welfare and affect his estimate of the value of things; only in so far as they are related to the one central subject of economic interest, the earning of a living.
Character of the social sciences
2. The social sciences deal with men and their relations with each other. The word "social" comes from the Latin socius, meaning a fellow, comrade, companion, associate. As men living together have to do with each other in a great many different ways, and enter into a great many different relations, there arise a great many different social problems. Each of the social sciences attempts to study man in some one important aspect—that is, to view these relations from some one standpoint.
Man's acts, his life, and his motives are so complex that it is not surprising that there has been less definiteness in the thought of the social sciences, and that they have advanced less rapidly toward exactness in their conclusions, than have the natural sciences. This complexity also explains the discouragement of the beginner in the early lessons in this subject. Usually the greatest difficulties appear in the first few weeks of its study. The thought is more abstract than in natural science; it requires a different, I will not say higher, kind of ability than does mathematics. But little by little the strangeness of the language and ideas disappears; the bare definitions become clothed with the facts of observation and recalled experiences; and soon the "economic" acts and relations of men in society come to be as real and as interesting to the student as are the materials in the natural world about him—often, indeed, more interesting.
Economics, politics, law, and ethics
3. Political economy is related to all the other social sciences, it being the study of certain of men's relations, while politics, law, and ethics have to do with other relations or with relations under a different aspect. Politics treats of the form and working of government and is mainly concerned with the question of power or control of the individual's actions and liberty. Law treats of the precepts and regulations in accordance with which the actions of men are limited by the state, and the contracts into which they have seen fit to enter are interpreted. Ethics treats the question of right or wrong, studies the moral aspects of men's acts and relations. The attempt just made to distinguish between the fields occupied by the various social sciences betrays at once the fundamental unity existing among them. The acts of men are closely related in their lives, but they may be looked at from different sides. The central thought in economics is the business relation, the relation of men in exchanging their services or material wealth. In pursuing economic inquiries we come into contact with political, legal, and ethical considerations, all of which must be recognized before a final practical answer can be given to any question. Nevertheless the province of economics is limited. It is because of the feebleness of our mental power that we divide and subdivide these complex questions and try to answer certain parts before we seek to answer the whole. When we attempt this final and more difficult task, we should rise to the standpoint of the social philosopher.
§ III. THE RELATION OF ECONOMICS TO PRACTICAL AFFAIRS
Economics is first a science
1. The ideal of political economy here set forth is that it should be a science, a search for truth, a systematized body of knowledge, arriving at a statement of the laws to which economic actions conform. It is not the advocacy of any particular policy or idea, but if it arrives at any conclusions, any truths, these cannot fail to affect the practical action of men.
But it touches many practical interests
Political economy, because defined as the science of wealth, has been described by some as a gospel of Mammon. It is hardly necessary to refute such a misconception. Political economy is not the science of wealth-getting for the individual. Its study is not primarily for the selfish ends and interest of the individual. (Certainly some of its lessons may be of practical value to men in active business) for many economic "principles" are but the general statement of those ideas that have been approved by the experience of business men, of statesmen, and of the masses of men. Some of its lessons must have educational value in practical business, for political economy is not dreamed out by the closet philosopher, but more and more it is the attempt to describe the interests and the action of the practical world in which men must live. Many men are working together to develop its study—those who collect statistics and facts bearing on all kinds of practical affairs, and those who search through the records of the past for illustrations of experiments and experiences that may help us in our life to-day.
Economic study needed in a democracy
2. But, in the main, the study of political economy is a social study for social ends and not a selfish study for individual advantage. The name political economy was first suggested in France when the government was monarchical and despotic in the extreme. As domestic economy indicates a set of rules or principles to guide wisely the action of the housekeeper or the owner of an estate, so political economy was first thought of as a set of rules or principles to guide the king and his counselors in the control of the state. The term has continued to bear something of that suggestion in it, though of late the term "economics," as being broader and less likely to be confused with politics, has very generally come into use. But in the degree in which unlimited monarchy has given way to the rule of the people, the conception of political economy has been modified. In a democracy there is need for a general diffusion of knowledge. The power now rests not with the king and a few counselors, but in the last resort with the people, and therefore the people must be acquainted with the experience of the past, must have all possible systematic knowledge to enlighten public policy and to guide legislation.
Is of growing interest and influence
Moreover, with the growth of the modern state, with the interest increasing importance of business, and of industrial and commercial interests, as compared with changes of dynasty or the personal rivalries of rulers, economic questions have grown in relative importance. In our own country, particularly since the subjects of slavery and of States' rights ceased to absorb the attention of our people, economic questions have pushed rapidly into the foreground. Indeed, it has of late been more clearly seen that many of the older political questions, such as the American Revolution and slavery, formerly discussed almost entirely in their political and constitutional aspects, were at bottom questions of economic rivalry and of economic welfare. The remarkable increase in the attention given to this study in colleges and universities in the last twenty years is but the index of the greatly increased interest and attention felt in it by citizens generally.
To sum up, it may be said that in the study of political economy we are seeking the reason, connection, and relations in the great multitude of acts arising out of the dependence of desires on the world of things and men.

ECONOMIC MOTIVES
§ I. MATERIAL WANTS, THE PRIMARY ECONOMIC MOTIVES
Feeling urges to economic actions
1. A logical explanation of industry must begin with a discussion of the nature of wants, for the purpose of industry is to gratify wants. An economic want may be defined as a feeling of
