Fortunately, as to the law of rent there is no necessity for discussion. Authority here coincides with common sense,^[1] and the accepted dictum of the current political economy has the self-evident character of a geometric axiom. This accepted law of rent, which John Stuart Mill denominates the pons asinorum of political economy, is sometimes styled "Ricardo's law of rent," from the fact that, although not the first to announce it, he first brought it prominently into notice.^[2] It is:

The rent of land is determined by the excess of its produce over that which the same application can secure from the least productive land in use.

This law, which of course applies to land used for other purposes than agriculture, and to all natural agencies, such as mines, fisheries, etc., has been exhaustively explained and illustrated by all the leading economists since Ricardo. But its mere statement has all the force of a self-evident proposition, for it is clear that the effect of competition is to make the lowest reward for which labor and capital will engage in production, the highest that they can claim; and hence to enable the owner of more productive land to appropriate in rent all

1. I do not mean to say that the accepted law of rent has never been disputed. In all the nonsense that in the present disjointed condition of the science has been printed as political economy, it would be hard to find anything that has not been disputed. But I mean to say that it has the sanction of all economic writers who are really to be regarded as authority. As John Stuart Mill says (Book II., Chap. XVI.). "there are few persons who have refused their assent to it, except from not having thoroughly understood it. The loose and inaccurate way in which it is often apprehended by those who affect to refute it is very remarkable." An observation which has received many later exemplifications.
2. According to McCulloch the law of rent was first stated in a pamphlet by Dr. James Anderson of Edinburgh in 1777, and simultaneously in the beginning of this century by Sir Edward West, Mr. Malthus, and Mr. Ricardo.
