Possibly some teachers will observe and regret the almost entire absence of critical discussions of controverted points in theory, which make up so large a part of some of the older texts. The more positive manner of presentation has been purposely adopted, and only such reference is made to conflicting views as is needed to guard the student against misunderstanding in his further reading. The author would not have it thought that he doubts the disciplinary value of economic theory or its scientific worth for more advanced students, for, on the contrary, he believes in it, perhaps to an extreme degree; but, for his own part, he has become convinced of the unwisdom of carrying on these subtle controversies in classes of beginners. The inherent difficulties of the subject are great enough, without the creation of new ones.
The fifty-seven chapters represent the work of the typical college course in elementary economics, allowing two chapters a week, and a third meeting weekly for review and for the discussion of questions, exercises, and reports. The subject is so large that the text is, in many places, hardly more than a suggestive outline. In class-room work it should be supplemented by other sources of information, such as personal observation by the students (many of the questions following the text serving to stimulate the attention); visits to local industries; interchange of opinions; examples given by the teacher; study and discussion, in the light of the principles stated in the text, of some such problems as are suggested in the appended list of questions; collateral reading; the preparation of exercises and the use of statistical material from the census, labor reports, etc.; history and description of industries; history of the growth of economic ideas. Suggestions, from teachers, of changes that will make the text more useful in their classes, will be thankfully received by the author.
Lack of space makes it impossible to mention by name the many sources to which the writer is indebted. Special acknowledgment, however, is gratefully made to C. H. Hull, of Cornell University; to E. W. Kemmerer, now of the Philippine Treasury Department, and to U. G. Weatherly, of Indiana University, who have read large portions of the manuscript, and have made many valuable suggestions; to W. M. Daniels, of Princeton University, who has read every page of the copy, and to whom are due the greatest obligations for his numerous and able criticisms both of the argument and of the expression; to R. C. Brooks, now of Swarthmore College, for a number of the questions in the appended list, and for helpful comments given while the course was developing; and to R. F. Hoxie and to A. C. Muhse, whose thoughtful reading of the proof has eliminated many errors. For the defects remaining, not these friendly critics, but the author alone, should be held accountable.
No book on economics can to-day satisfy everybody—"Or even anybody," adds a friend. But with this book may go the hope that what has been written with love of truth and of democracy may serve, in its small way, both to further sound economic reasoning and to extend among American citizens a better understanding of the economic problems set for this generation to solve.

CHAPTER I
THE NATURE AND PURPOSE OF POLITICAL ECONOMY
§ I. NAME AND DEFINITION
Verbal definition of economics
1. Economics, or political economy, may be defined, briefly, as the study of men earning a living; or, more fully, as the study of the material world and of the activities and mutual relations of men, so far as all these are the objective conditions to gratifying desires. To define, means to mark off the limits of a subject, to tell what questions are or are not included within it. The ideas of most persons on this subject are vague, yet it would be very desirable if the student could approach this study with an exact understanding of the nature of the questions with which it deals. Until a subject has been studied, however, a definition in mere words cannot greatly aid in marking it off clearly in our thought. The essential thing for the student is to see clearly the central purpose of the study, not to decide at once all of the puzzling cases.
Natural sciences deal with material things
2. A definition that suggests clear and familiar thoughts to the student seem at first much more difficult to get in any social science than in the natural sciences. These deal with concrete, material things which we are accustomed to see, handle, and measure. If a mere child is told that botany is a study in which he may learn about flowers, trees, and plants, the answer is fairly satisfying, for he at once thinks of many things of that kind. When, in like manner zoölogy is defined as the study of animals, or geology as the study of rocks and the earth, the words call up memories of many familiar objects. Even so difficult and foreign-looking a word as ichthyology seems to be made clear by the statement that it is the name of the study in which one learns about fish. It is true that there may be some misunderstanding as to the way in which these subjects are studied, for botany is not in the main to teach how to cultivate plants in the garden, nor ichthyology how to catch fish or to propagate them in a pond. But the main purpose of these studies is clear at the outset from these simple definitions. Indeed, as the study is pursued, and knowledge widens to take in the manifold and various forms of life, the boundaries of the special sciences become not more but less sharp and definite.
Economics studies some social acts and relations
Political economy, on the other hand, as one of the social sciences, which deal with men and their relations in society, seems to be a very much more complex thought to get hold of. We are tempted to say that it deals with less familiar things; but the truth may be, as a thoughtful friend suggests, that the simple social acts and relations are more familiar to our thought than are lions, palm-trees, or even horses. Every hour in the streets or stores, one may witness thousands of acts, such as bargains, labor, payments, that are the subject-matter of economic science. Their very familiarity may cause men to overlook their deeper meaning.
Many other definitions have been given of political economy. It has been called the science of wealth, or the science of exchanges. Evidently there are various ways in which wealth may be considered or exchanges made. The particular aspects that are dealt with in political economy will be made clear by considering two other questions, the place of economics among the social sciences and the relation of economics to practical affairs.
