Published in two volumes or as a set this provides a definitive scholarly variorum edition of Malthus's Principles of Political Economy. It contains the full text of the first 1820 edition, including Malthus's own invaluable 70-page summary, and contains details of all the additions, omissions and emendations that occurred between the first and the second, posthumous, edition of 1836. The first edition is extremely rare, and for over 150 years confusions and disagreements have inevitably occurred in the interpretation of Malthus's economics because of the absence of any systematic record of the differences between the two editions. The editor has written a lengthy and authoritative introduction giving an account, derived mainly from contemporary correspondence, of the events and circumstances surrounding the publication of the two editions. It shows the relationship between the Principles and Malthus's other writings and activities as a political economist. There is also an editorial commentary that aims to explain the significance and origin of the alterations.
The Rev. Thomas Robert Malthus FRS was an English cleric and scholar, influential in the fields of political economy and demography. Malthus himself used only his middle name Robert.
His An Essay on the Principle of Population observed that sooner or later population will be checked by famine and disease, leading to what is known as a Malthusian catastrophe. He wrote in opposition to the popular view in 18th-century Europe that saw society as improving and in principle as perfectible. He thought that the dangers of population growth precluded progress towards a utopian society: "The power of population is indefinitely greater than the power in the earth to produce subsistence for man". As an Anglican cleric, Malthus saw this situation as divinely imposed to teach virtuous behaviour. Malthus wrote:
That the increase of population is necessarily limited by the means of subsistence, That population does invariably increase when the means of subsistence increase, and, That the superior power of population is repressed, and the actual population kept equal to the means of subsistence, by misery and vice.
Malthus placed the longer-term stability of the economy above short-term expediency. He criticized the Poor Laws, and (alone among important contemporary economists) supported the Corn Laws, which introduced a system of taxes on British imports of wheat. His views became influential, and controversial, across economic, political, social and scientific thought. Pioneers of evolutionary biology read him, notably Charles Darwin and Alfred Russel Wallace. He remains a much-debated writer.
