Ebook The Common Sense of Political Economy

This book is intended primarily as a popular but systematic exposition of the "marginal" theory of Economics. The Introduction will make it clear that the author makes no claim to originality or priority with respect to anything that it contains. It is not a history; and the question it is concerned with is not who first made any given application of the "marginal" theory to Economics, but what are the main applications of that theory inevitably demanded by the facts. The general absence of references or acknowledgments, therefore, must not in any case be regarded as an implied claim on the author's part to a special property in the argument or illustration in question.

But whereas this general explanation will, I hope, clear me from the charge of ingratitude, or worse, with reference to the great masters and the published works on Economics, it cannot absolve me from the duty of registering some few of the personal obligations under which I have from time to time been laid during the many years over which the direct and indirect preparations for this work have extended.

To Mr. Graham Wallas, to Mr. H. H. Cunynghame, and to several members of my own family, I owe criticisms or suggestions which they may well have forgotten, but which have been of decisive importance to the development of my own thought.
