The problem of reading asks how we can acquire the greatest number of ideas, and how we can arrive at truth rather than the verdict of an author. It assumes a limited time and asks how we can use that time most profitably. Not least of all, it asks how we can best combine our reading with original thought. From the remarks already made, it is evident that we cannot prescribe any one method for dealing with all books. Even works of similar nature and merit will be treated in different ways, depending on the order in which we read them, and like conditions. The mastery of any book will not be an end in itself. It will be subordinated to the larger end of obtaining the best from reading as a whole. But for the sake of clearness, I shall for the present consider our end as the mastery of some particular subject, and shall indicate a plan of reading to best serve that end. Needful qualifications will come later. I shall first outline a typical plan of study, and then review and explain it in detail. Assuming you have chosen a subject, your first step should be to do a little unaided thinking on it. Next I would advise the selection of a comprehensive text book. This should be read critically and written note made of the problems taken up which you do not believe have been adequately treated, or the solutions of which are in any way unsatisfactory. These you should think out for yourself. A second book may in some cases be read in the same thorough manner as this first one, and the problems recorded in the same way. After that all books on that subject may be read “hop, skip and jump” fashion, for the new problems or solutions they suggest. I do not expect the foregoing plan to be strictly adhered to, for the nature of the subject studied will make certain changes necessary. However, it demands more detailed explanation and perhaps defense. Let us take up the first step advised—giving a little unaided thought to the subject. My only reason for advising “a little” thinking, is that I know if I asked more the reader would probably do nothing at all. Indeed many readers will fail to see the necessity of thinking about a subject before studying it. Many may even question the possibility of doing so. “How is a man to think about a subject on which he knows nothing?” you ask. Let us, however, consider. The very fact that you want to study a subject implies that the phenomena with which it deals are not clear to you. You desire to study economics, for instance, because you feel that you do not understand everything you should about the production, distribution and consumption of wealth. In other words, something about these phenomena puzzles you—you have some unsolved problems. Very well. These problems are your materials. Try to solve them. “But how can I solve them when I know nothing of economics?”
