Note 64 — THOMAS ROBERT MALTHUS.

Announced as early as 1807 in the reply to Spence ('Commerce Defended'). Ricardo's friendship with James Mill seems to have begun about the year 1811: 'With an estimate of his [Ricardo's] value in the cause of mankind, which to most men would appear to be mere extravagance, I have the recollection of a dozen years of the most delightful intercourse, during the greater part of which time he had hardly a thought or purpose, respecting either public or his private affairs, in which I was not his confidant and adviser.' Letter of Jas. Mill to MacCulloch, 19th Sept. 1823 (Bain's Life of Jas. Mill, p. 209).
