The point is fundamental; any difference of opinion on it involves radically different conceptions of Political Economy, especially in its practical aspect. On the one view, we have only to consider how a sufficient production may be combined with the best possible distribution; but, on the other, there is a third thing to be considered—how a market can be created for produce, or how production can be limited to the capabilities of the market. Besides, a theory so essentially self-contradictory cannot intrude itself without carrying confusion into the very heart of the subject, and making it impossible even to conceive with any distinctness many of the more complicated economical workings of society. This error has been, I conceive, fatal to the systems, as systems, of the three distinguished economists to whom I before referred, Malthus, Chalmers, and Sismondi; all of whom have admirably conceived and explained several of the elementary theorems of political economy, but this fatal misconception has spread itself like a veil between them and the more difficult portions of the subject, not suffering one ray of light to penetrate. Still more is this same confused idea constantly crossing and bewildering the speculations of minds inferior to theirs. It is but justice to two eminent names to call attention to the fact, that the merit of having placed this most important point in its true light belongs principally, on the Continent, to the judicious J. B. Say, and in this country to Mr. [James] Mill; who (besides the conclusive exposition which he gave of the subject in his
Elements of Political Economy) had set forth the correct doctrine with great force and clearness in an early pamphlet, called forth by a temporary controversy, and entitled,
Commerce Defended; the first of his writings which attained any celebrity, and which he prized more as having been his first introduction to the friendship of David Ricardo, the most valued and most intimate friendship of his life.
