PART III. THE VALUE OF MONEY
CHAPTER XX
RECAPITULATION OF POSITIVE DOCTRINE
The chapters which have gone before have been, in considerable degree, concerned with the analysis of unsuccessful efforts to solve the problem of the value of money, as the quantity theory, or the attempts to apply the notions of supply and demand, marginal utility, and cost of production, to the problem. Not all that has gone before has been, even in form, primarily critical. The chapter on "Economic Value" lays the foundation for the main constructive theory of the book, and in virtually every chapter some portion of our positive doctrine has been developed. In the doctrines criticised, elements of truth have been noted, and in showing the errors of the doctrines considered, constructive doctrine has been presented by way of contrast. The theories criticised, moreover, even where they have gone astray in solving problems, have at least the merit of stating problems, and so have aided in clearing the way for theories better based.
It is the task of the present chapter to present, in a series of theses, the main constructive results so far attained. No effort will be made to follow the order of the exposition which has preceded. A summary of that will be found in the detailed analytical table of contents. Rather, we shall seek to draw from what has preceded the positive doctrine which is scattered through the preceding chapters, and to present it by itself, as a basis for the more systematic formulation of constructive theory which the following chapters are to contain.
1. The theory of the value of money is a special case of the general theory of value.
