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.
