See Note I. in the Mathematical Appendix at the end of the Volume. This law holds a priority of position to the
law of diminishing return
from land; which however has the priority in time; since it was the first to be subjected to a rigid analysis of a semi-mathematical character. And if by anticipation we borrow some of its terms, we may say that the
of pleasure which a person gets from each additional
of a commodity diminishes till at last a margin is reached at which it is no longer worth his while to acquire any more of it.
marginal utility (
Grenz-nutz) was first used in this connection by the Austrian Wieser. It has been adopted by Prof. Wicksteed. It corresponds to the term
Final used by Jevons, to whom Wieser makes his acknowledgments in the Preface (p. xxiii. of the English edition). His list of anticipators of his doctrine is headed by Gossen, 1854.
