Note 111 — Chapter VII · THE EMPIRICAL THEORY AS DEVELOPED BY MALTHUS.
Reading edition
The law of supply and demand is not so simple as to preclude a variety of ways of stating it, and the meaning of such conceptions as intensity of demand, equilibrium or balance of supply and demand, etc., requires careful reasoning to define. The history of the law in English political economy would be concerned mainly with Malthus, J. S. Mill, Cairnes and Marshall.
