Thomas Malthus

The Rev. Thomas Robert Malthus (February, 1766 – December 23, 1834), who is usually known as Thomas Malthus, although he preferred to be known as "Robert Malthus," was an English demographer and political economist best known for his pessimistic but highly influential views. Although it is popularly assumed that it was these pessimistic views that gave economics the nickname Dismal Science, the phrase was actually coined by the historian Thomas Carlyle in reference to an anti-slavery essay written by John Stuart Mill.

Demographic theory

Malthus's views were largely developed in reaction to the optimistic views of his father and his associates, notably Rousseau and William Godwin. In An Essay on the Principle of Population, published in 1798, Malthus predicted population would outrun food supply, leading to a decrease in food per person. This prediction was based on the idea that population if unchecked increases at a geometric rate (i.e. 2, 4, 8, 16, 32, 64, 128, etc.) whereas the food supply grows at an arithmetic rate (i.e. 1, 2, 3, 4, 5, 6, 7, etc.) (See Malthusian catastrophe for more information.) Only misery, moral restraint and vice (which for Malthus included contraception) could check excessive population growth. Malthus favoured "moral restraint" (including late marriage and sexual abstinence) as a check on population growth. However, it is worth noting that Malthus proposed this only for the working and poor classes. Thus, the lower social classes took a great deal of responsibility for societal ills, according to his theory. Essentially what this resulted in was the promotion of legislation which degenerated the conditions of the poor in England.
