The Reverend Thomas Robert Malthus FRS (13 February 1766 – 23 December 1834^[1]) was an English scholar who did influential work in political economy and demography.

Malthus came to prominence for drawing attention to the potential dangers of population growth: "The power of population is indefinitely greater than the power in the earth to produce subsistence for man". ^[2] As an Anglican clergyman, Malthus saw this situation as divinely imposed to teach virtuous behaviour: he regarded optimistic ideas of social reform as doomed to failure.^[3] He thus presented to the reader a dystopian, negative, view of the world, in contrast to the eutopias of writers such as Rousseau and William Godwin. A disaster occurring as a consequence of population growth outstripping resources is known as a Malthusian catastrophe.

Malthus placed the longer-term stability of the economy above short-term expediency. He criticised the Poor Laws,^[4] and (alone among important contemporary economists) supported the Corn Laws, which introduced a system of taxes on British imports of wheat. He thought these measures would encourage domestic production, and so promote long-term benefit.^[5]

Malthus became hugely influential, and controversial, in economic, political, social and scientific thought. Many of the later evolutionary biologists read him,^[6] particularly Charles Darwin and Alfred Russel Wallace, for whom Malthusianism became an intellectual stepping-stone to the idea of the survival of the fittest.^[7][8] Malthus remains a writer of great significance.

Modern commentators generally refer to him as Thomas Malthus, but during his lifetime he went by his middle name, Robert.

[edit] Biography

Thomas Robert Malthus, the younger son among eight children born to Daniel and Henrietta Malthus, grew up in a country house, The Rookery, near Guildford in Surrey. The family was prosperous; his father was a personal friend of the philosopher David Hume and an acquaintance of Jean-Jacques Rousseau. The young Malthus received his education at home in Bramcote, Nottinghamshire and at the Dissenting Warrington Academy, until his admission to Jesus College, Cambridge in 1784. There he took prizes in English declamation, Latin and Greek, but he graduated in mathematics. He took the MA degree in 1791, and was elected a Fellow of Jesus College, Cambridge two years later.^[9] In 1797, he took orders and became an Anglican country curate at Okewood near Albury in Surrey.^[10]

His portrait,^[11] and descriptions by contemporaries, present him as tall and good-looking, but with a hare-lip and cleft palate.^[12] Malthus apparently refused to have his portrait painted until 1833 because of embarrassment over the cleft lip. His cleft palate affected his speech: such birth defects had occurred before amongst his relatives.^[13]

Malthus married his cousin, Harriet, on April 12, 1804, and had three children: Henry, Emily and Lucy. In 1805 he became Professor of History and Political Economy at the East India Company College (now known as Haileybury) in Hertfordshire.^[14] His students affectionately referred to him as "Pop" or "Population" Malthus. In 1818 Malthus became a Fellow of the Royal Society.

[edit] The Principle of Population

Between 1798 and 1826 Malthus published six editions of his famous treatise, An Essay on the Principle of Population, updating each edition to incorporate new material, to address criticism, and to convey changes in his own perspectives on the subject. He wrote the original text in reaction to the optimism of his father and his father's associates, (notably Rousseau) regarding the future improvement of society. Malthus also constructed his case as a specific response to writings of William Godwin (1756-1836) and of the Marquis de Condorcet (1743-1794).

Malthus regarded ideals of future improvement in the lot of humanity with scepticism, considering that throughout history a segment of every human population seemed relegated to poverty. He explained this phenomenon by pointing out that population growth generally preceded expansion of the population's resources, in particular the primary resource of food.

In evaluating Malthus one can usefully distinguish between his primary (and virtually irrefutable) axioms, and the consequences he drew from the axioms, which have not always met with consensus agreement.

[edit] Primary theory: the axioms

"The power of population is indefinitely greater than the power in the earth to produce subsistence for man. Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio. A slight acquaintance with numbers will show the immensity of the first power in comparison with the second." ^[15] See also Malthusian growth model.

[edit] Secondary theory: the consequences

"Yet in all societies, even those that are most vicious, the tendency to a virtuous attachment is so strong that there is a constant effort towards an increase of population. This constant effort as constantly tends to subject the lower classes of the society to distress and to prevent any great permanent amelioration of their condition." ^[16]

"The way in which, these effects are produced seems to be this. We will suppose the means of subsistence in any country just equal to the easy support of its inhabitants. The constant effort towards population... increases the number of people before the means of subsistence are increased. The food therefore which before supported seven millions must now be divided among seven millions and a half or eight millions. The poor consequently must live much worse, and many of them be reduced to severe distress. The number of labourers also being above the proportion of the work in the market, the price of labour must tend toward a decrease, while the price of provisions would at the same time tend to rise. The labourer therefore must work harder to earn the same as he did before. During this season of distress, the discouragements to marriage, and the difficulty of rearing a family are so great that population is at a stand. In the mean time the cheapness of labour, the plenty of labourers, and the necessity of an increased industry amongst them, encourage cultivators to employ more labour upon their land, to turn up fresh soil, and to manure and improve more completely what is already in tillage, till ultimately the means of subsistence become in the same proportion to the population as at the period from which we set out. The situation of the labourer being then again tolerably comfortable, the restraints to population are in some degree loosened, and the same retrograde and progressive movements with respect to happiness are repeated." ^[17]

Malthus also saw that societies through history had experienced at one time or another epidemics, famines, or wars: events that masked the fundamental problem of populations overstretching their resource limitations:

"The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race. The vices of mankind are active and able ministers of depopulation. They are the precursors in the great army of destruction, and often finish the dreadful work themselves. But should they fail in this war of extermination, sickly seasons, epidemics, pestilence, and plague advance in terrific array, and sweep off their thousands and tens of thousands. Should success be still incomplete, gigantic inevitable famine stalks in the rear, and with one mighty blow levels the population with the food of the world." ^[18]

The following passage suggests that techniques of animal husbandry could apply to humans, anticipating the idea which, in 1883, Francis Galton called eugenics:

"It does not... by any means seem impossible that by an attention to breed, a certain degree of improvement, similar to that among animals, might take place among men. Whether intellect could be communicated may be a matter of doubt; but size, strength, beauty, complexion, and perhaps longevity are in a degree transmissible... As the human race, however, could not be improved in this way without condemning all the bad specimens to celibacy, it is not probable that an attention to breed should ever become general." ^[19]

[edit] Proposed solutions

"Malthus argued that population was held within resource limits by two types of checks: positive ones, which raised the death rate, and preventative ones, which lowered the birth rate. The positive checks included hunger, disease and war; the preventative checks, abortion, birth control, prostitution, postponement of marriage, and celibacy." ^[20]

In the second and subsequent editions, with his name on the title page, Malthus put more emphasis on moral restraint. By that he meant the postponement of marriage until people could support a family, coupled with strict celibacy (sexual abstinence) until that time. "He went so far as to claim that moral restraint on a wide scale was the best means—indeed, the only means—of easing the poverty of the lower classes." ^[21] This plan appeared consistent with virtue, economic gain and social improvement.

This train of thought makes Malthus's stand on public assistance to the poor especially interesting. He proposed the gradual abolition of poor laws by gradually reducing the number of persons qualifying for relief. Relief in dire distress would come from private charity.^[22] He reasoned that poor relief acted against the longer-term interests of the poor by raising the price of commodities and undermining the independence and resilience of the peasant.^{[citation needed]} In other words, the poor laws tended to "create the poor which they maintain".^[23]

It offended Malthus that critics claimed he lacked a caring attitude towards the situation of the poor. He wrote in an addition to the 1817 edition:

"I have written a chapter expressly on the practical direction of our charity; and in detached passages elsewhere have paid a just tribute to the exalted virtue of benevolence. To those who have read these parts of my work, and have attended to the general tone and spirit of the whole, I willingly appeal, if they are but tolerably candid, against these charges ... which intimate that I would root out the virtues of charity and benevolence without regard to the exaltation which they bestow on the moral dignity of our nature...^[24]

Some, such as William Farr^[25] and Karl Marx,^[26] argued that Malthus did not fully recognize the human capacity to increase food supply. On this subject Malthus wrote: "The main peculiarity which distinguishes man from other animals, is the means of his support, is the power which he possesses of very greatly increasing these means.^{[citation needed]}

[edit] Malthus's expectations of growth in population

Since 1800, global food production has greatly increased, but whether it has generally kept pace with population growth remains a matter for debate (see the multiple millions of deaths summarised and itemised in List of famines). Some call for new ways "to increase yields while preserving natural habitats and biodiversity",^[28] but Malthusianism would reject^{[citation needed]} this possibility.

Elwell states that Malthus made no specific prediction regarding the future; and that what some interpret as prediction merely constituted Malthus's illustration of the power of geometric/exponential population growth compared to the arithmetic growth of food-production.^[29]

Rather than predicting the future, the Essay offers an evolutionary social theory. Eight major points regarding evolution appear in the 1798 Essay:^[30]

1. subsistence severely limits population-level
2. when the means of subsistence increases, population increases
3. population-pressures stimulate increases in productivity
4. increases in productivity stimulate further population-growth
5. because productivity increases cannot maintain the potential rate of population growth, population requires strong checks to keep parity with the carrying-capacity
6. individual cost/benefit decisions regarding sex, work, and children determine the expansion or contraction of population and production
7. checks will come into operation as population exceeds subsistence-level
8. the nature of these checks will have significant effect on the larger sociocultural system — Malthus points specifically to misery, vice, and poverty

Malthusian theory has had great influence on evolutionary theory, both in biology (as acknowledged by Darwin and Alfred Russel Wallace) and in the social sciences (compare Herbert Spencer). Malthus's population theory has also profoundly affected the modern-day^[update] ecological-evolutionary social theory of Gerhard Lenski and Marvin Harris. He can thus rank as a key contributing element of the canon of socioeconomic theory.

[edit] Reactions to Malthusian ideas

Malthus became subject to extraordinary personal criticism. People who knew nothing about his private life criticised him both for having no children, and for having too many. In 1819, Shelley, berating Malthus as a priest, called him "a eunuch and a tyrant" (though the Church of England does not require celibacy, and Malthus married in 1804).^[31] Marx repeated the lie, adding that Malthus had taken the vow of celibacy, and called him "superficial", "a professional plagiarist", "the agent of the landed aristocracy", "a paid advocate" and "the principal enemy of the people." ^[32] In the 20th century an editor of the Everyman edition of Malthus claimed that Malthus had practised population control by begetting eleven girls.^[33] (In fact Malthus fathered two girls and one son.) Garrett Hardin provides an overview of these personal insults.^[34]

[edit] Contemporaries of Malthus

William Godwin responded to Malthus's criticisms of his own arguments with On Population (1820).

Other theoretical and political critiques of Malthus and Malthusian thinking emerged soon after the publication of the first Essay on Population, most notably in the work of the reformist industrialist Robert Owen, of the essayist William Hazlitt^[35] and of the economists John Stuart Mill and Nassau William Senior,^[36] and moralist William Cobbett. Note also True Law of Population (1845) by politician Thomas Doubleday, an adherent of Cobbett's views.

[edit] Marxist

Other opposition to Malthus's ideas came from the middle of the nineteenth century with the writings of Karl Marx (Capital, 1867) and Friedrich Engels (Outlines of a Critique of Political Economy, 1844), who argued that what Malthus saw as the problem of the pressure of population on the means of production actually represented the pressure of the means of production on population. They thus viewed it in terms of their concept of the reserve army of labour. In other words, the seeming excess of population that Malthus attributed to the seemingly innate disposition of the poor to reproduce beyond their means actually emerged as a product of the very dynamic of capitalist economy.

Engels called Malthus's hypothesis "...the crudest, most barbarous theory that ever existed, a system of despair which struck down all those beautiful phrases about love thy neighbour and world citizenship." ^[37]

Vladimir I. Lenin sharply criticized Malthusian theory and its neo-Malthusian version,^[38] calling it a "reactionary doctrine" and "an attempt on the part of bourgeois ideologists to exonerate capitalism and to prove the inevitability of privation and misery for the working class under any social system".

[edit] Biological

Critical commentary on Malthus by biologists^[who?] largely addresses matters peripheral to his main premises. For example, complaints^{[by whom?]} that it justifies conservative social policies or that it leads to policies such as eugenics, represent "concerned citizen" complaints^{[citation needed]}, which apply to the secondary theory, or consequences. Such criticisms do not arise from the technical work of the professional biologist.^{[citation needed]}

Darwin and Wallace both read and acknowledged the positive role played by Malthus in the development of their own ideas:

"In October 1838... I happened to read for amusement Malthus on Population... it at once struck me that under these circumstances favourable variations would tend to be preserved, and unfavourable ones to be destroyed. The result of this would be the formation of new species." ^[39]

Ronald Fisher expressed criticism of the use of Malthus's theory as a basis for a theory of natural selection. Fisher did not deny Malthus's basic premises, but emphasised that natural selection can alter fecundity.^[40]

John Maynard Smith doubted that famine functioned as the great leveler that Malthus portrayed it as, but he also accepted the basic premises:

"[A population] cannot increase logarithmically for ever. Sooner or later, a shortage of resources must bring the increase to a halt. It was this insight which led both Darwin and Wallace acquired by reading... Malthus, and which led to the idea of natural selection." ^[41]

[edit] Cornucopian

Some 19th-century economists^[who?] believed that improvements in finance, maufacturing and science rendered some of Malthus's warnings implausible. They had in mind the division and specialization of labor, increased capital investment, and increased productivity of the land due to the introduction of science into agriculture (Justus Liebig; Sir John Bennet Lawes). Even in the absence of improvement in technology or increase of capital equipment, an increased supply of labor may have a synergistic effect on productivity that overcomes the law of diminishing returns. As American land-economist Henry George observed with characteristic piquancy in dismissing Malthus: "Both the jayhawk and the man eat chickens; but the more jayhawks, the fewer chickens, while the more men, the more chickens."

Many^{[weasel words]} 20th-century economists, such as Julian Lincoln Simon, have also criticised Malthus's conclusions.^[42] They note that despite the predictions of Malthus and the Neo-Malthusians, massive geometric population growth in the 20th century did not result in a Malthusian catastrophe, largely due to the influence of technological advances^{[citation needed]} and the expansion of the market economy^{[citation needed]}, division of labor^{[citation needed]}, and stock of capital goods^{[citation needed]}. The enviro-sceptic Bjørn Lomborg, echoes such arguments, and presents data showing that the environment has actually improved.^[43] Those who regard Malthus as a failed prophet of doom include a former editor of Nature, John Maddox.^[44]

[edit] Anthropological

Anthropologist Eric Ross depicts Malthus's work as a rationalization of the social inequities produced by the Industrial Revolution, anti-immigration movements, the eugenics movement and the various international development movements.^[45]

[edit] Economic

Malthus argued that as wages increase within an economy, the birth-rate increases while the death-rate decreases. He reasoned that high incomes allowed people to have sufficient means to raise their children, thus resulting in greater desire to have more children, which increases the population. In addition, high incomes also allowed people to afford proper medication to fight off potentially harmful diseases, thus decreasing the death-rate. As a result, wage-increases caused population to grow as the birth-rate increases and the death-rate decreases. He further argued that as the supply of labor increases with the increased population-growth at a constant labor demand, the wages earned would decrease eventually to subsistence, where the birth-rate equals the death-rate, resulting in no growth in population^{[citation needed]}.

The examples and perspective in this section deal primarily with the northern hemisphere and do not represent a worldwide view of the subject. Please improve this article or discuss the issue on the talk page.

However, the world generally has not developed in accordance with Malthus's expectations. During the late 19th and early 20th century, the population (and wages) increased as the industrial revolution gathered pace. However, birth rates in highly-developed nations have dropped to bare replacement-levels, such that many Western nations like the US and Canada only grow due to immigration, and Japan faces a declining population when the post-World War II generation dies off.

Malthus assumed a constant labor-demand in his assessment of England^{[citation needed]}, and in doing so he ignored the effects of industrialization. As the world became more industrialized, the level of technology and production grew, causing an increase in labor-demand. Thus, even though labor-supply increased, so did the demand for labor. In fact, the labor-demand arguably increased more than the supply, as measured by the historically observed increase in real wages globally with population growth.

His main work presents a theory of irremediable, if not untreatable, scarcity: one could classify it in a general category called Scarcity Theory. Three of his works present material that falls under the theory of surplus value:

1. (1815) The nature of Rent
2. (1820) Principles of political economy^[46]
3. (1827) Definitions in Political Economy ^[47].

The Nature of Rent proposes rent as a kind of surplus, whereas the previous general definition of rent portrayed it as an societal economic loss caused by personal financial gain derived from land scarcity.^[48]

Principles of Political Economy and Definitions in Political Economy defend^[49] the concept of the general glut, a theory that surplus value can present a problem. Rent as surplus, and a glut or surplus of goods as problems differ somewhat or stand in contradistinction to Malthus's earlier scarcity theory of The Principle of Population.

[edit] 1800: The present high price of provisions

In this work, his first published pamphlet, Malthus argues against the notion prevailing in his locale that the greed of intermediaries caused the high price of provisions. Instead, Malthus says that the high price stems from the Poor Laws which "increase the parish allowances in proportion to the price of corn". Thus, given a limited supply, the Poor Laws force up the price of daily necessities. Then he concludes by saying that in time of scarcity such Poor Laws, by raising the price of corn more evenly, produce a beneficial effect.^[50]

[edit] 1814: Observations on the effects of the Corn Laws

Although government in Britain had regulated the prices of corn (wheat) since the seventeenth century^{[citation needed]}, the Corn Laws originated in 1815. At the end of the Napoleonic Wars that year, Parliament passed legislation banning the importation of foreign corn into Britain until domestic corn cost 80 shillings per quarter. The high price caused the cost of food to increase and so caused great distress among the working classes in the towns. This led to serious rioting in London and to the "Peterloo Massacre" (1819) in Manchester.^[51][52]

In this pamphlet, printed during the parliamentary discussion, Malthus tentatively supported the free traders. He argued that. given the increasing expense of raising British corn, advantages accrued from supplementing it from cheaper foreign sources. This view he changed the following year.

[edit] 1815: The Nature of Rent

Rent constitutes a major concept in economics. David Ricardo, Malthus' contemporary and friendly rival, defined a theory of rent in his Principles of Political Economy (1817). Ricardo regarded rent as value in excess of real production — something caused by incident of ownership rather than by fundamental economic value imparted by free and equal trade. For Ricardo, rent represented a kind of negative money that landlords could pull out of the production of the land by measure of land's scarcity.^[53]

Contrary to this concept of rent, Malthus states that rent cannot exist except in the case of surplus. Also he says that rent, once accumulated, becomes subsequently a source of capital re-investment, causing positive effects through the growth and accumulation of productive wealth. He proposes rent to be a kind of surplus.

[edit] 1815: The policy of restricting the importation of Grain

Malthus emerged as the only economist of note to support customs duty on imported grain.^[54]

He had changed his mind from the previous year, siding now with the protectionists. Foreign laws, he noted, often prohibit or raise taxes on the export of corn in lean times, which meant that the British food supply could become captive to foreign politics. By encouraging domestic production, Malthus argued, the Corn Laws would guarantee British self-sufficiency in food.^[55]

[edit] 1820: Principles of political economy

1836: Second edition, posthumously published.

Malthus intended this work to rival Ricardo's Principles (1817). It, and his 1827 Definitions in political economy (below), defend Sismondi's views on general glut as against Say's Law. Say's Law states, "there can be no general glut". A general glut falls under the general category of what we might term Malthus's "Surplus Theory", rather his main, and earlier, body of work, what can be called his "Scarcity Theory".

[edit] 1823: The Measure of Value, stated and illustrated

[edit] 1827: Definitions in political economy

"The question of a glut is exclusively whether it may be general, as well as particular, and not whether it may be permanent as well as temporary...[The] tendency, in the natural course of things, to cure a glut or scarcity, is no more a proof that such evils have never existed, than the tendency of the healing processes of nature to cure some disorders without assistance from man, is a proof that such disorders never existed." ^[56]

Malthus's contribution to general glut theory would seem contrary to his main and more famous work on scarcity theory.

[edit] Malthus on religion

As a believer and a clergyman, Malthus held that God had created the inexorable tendency to population growth for a moral purpose, with the constant harsh threat of poverty and starvation designed to teach the virtues of hard work and virtuous behaviour.^[3]

The problem faced by Malthus has occurred to many believers: why should an omnipotent and caring God permit the existence of wickedness and suffering in the world? Malthus's theodicy answers that evil energizes mankind in the struggle for good. "Had population and food increased in the same ratio, it is probable that man might never have emerged from the savage state". The principle of population represented more than the difference between an arithmetic and a geometric series; it provided the spur for constructive activity:

"Evil exists in the world not to create despair, but activity." ^[57]

Malthus saw "the infinite variety of nature" which "cannot exist without inferior parts, or apparent blemishes"^{[cite this quote]}. Such diversity and struggle functioned to enable the development of improved forms. Without such a contest, no species would feel impelled to improve itself. Without the test of struggle, and the failure or even death of some, no successful development of the population as a whole would take place. For Malthus, evil invigorates good and death replenishes life. Malthus painted a picture of fecundity in the face of enduring resource-scarcity, in which adversity and evil can stimulate beneficial outcomes.^[58]

[edit] Influence

Malthus's theory of population has proven very influential. In fact, in 1978 Michael H. Hart published a book called The 100: A Ranking of the Most Influential Persons in History, which placed Malthus at number 80 in this worldwide ranking.

At Haileybury, Malthus developed a theory of demand-supply mismatches which he called gluts. Considered ridiculous at the time, his theory foreshadowed later theories about the Great Depression, and the works of economist and Malthus-admirer John Maynard Keynes.

Malthus's position as professor at the British East India Company training college, which he held until his death in 1834, gave his theories considerable influence over Britain's administration of India through most of the 19th century, continuing even under the Raj after the Company's dissolution in 1858. The official response to India's periodic famines (which had occurred every decade or two for centuries) became one of not entirely benign neglect: the authorities regarded the famines as necessary to keep the "excess" population in check.

A distinguished early convert to Malthusianism, British Prime Minister William Pitt The Younger (in office: 1783–1801 and 1804–1806), after reading the work of Malthus promptly withdrew a Bill he had introduced that called for the extension of Poor Relief. Concerns about Malthus's theory helped promote the idea of a national population census in the UK. Government official John Rickman became instrumental in the carrying out of the first modern British census in 1801, under Pitt's administration. In the 1830s Malthus's writings strongly influenced Whig reforms which overturned Tory paternalism and brought in the Poor Law Amendment Act of 1834.

Before Malthus, commentators had regarded high fertility as an economic advantage, because it increased the number of workers available to the economy. Malthus, however, looked at fertility from a new perspective and convinced most economists that even though high fertility might increase the gross output, it tended to reduce output per capita. A number of other notable economists, such as David Ricardo (whom Malthus knew personally) and Alfred Marshall admired Malthus and/or came under his influence. Malthus took pride in the fact that some of the earliest converts to his population theory included Archdeacon William Paley, whose Natural Theology first appeared in 1802. Ironically, given Malthus's own opposition to contraception, his work exercised a strong influence on Francis Place (1771–1854), whose Neo-Malthusian movement became the first to advocate contraception. Place published his Illustrations and Proofs of the Principles of Population in 1822.

Malthus's idea of man's struggle for existence had an influence on the inception of Darwin's theory of evolution, along with A. P. de Candolle's idea of "nature's war". The metaphor of struggle for existence provides the explanation of how natural selection can produces the "survival of the fittest", a phrase of Herbert Spencer.^[59] Darwin, in The Origin of Species, called his theory an application of the doctrines of Malthus in an area without the complicating factor of human intelligence. Darwin referred to Malthus as "that great philosopher"^[60] and wrote in his notebook that "Malthus on Man should be studied". Wallace called Malthus's essay "...the most important book I read..." and considered it "the most interesting coincidence" that reading Malthus led both himself and Darwin, independently, towards the idea of evolution.^[61]

The first Director-General of UNESCO, evolutionist and humanist Julian Huxley, wrote of The crowded world in his Evolutionary Humanism (1964), calling for a World population policy. Huxley openly criticised Communist and Roman Catholic attitudes to birth control, population control and overpopulation.

Malthusian ideas continue to have considerable influence. Paul R. Ehrlich has written several books predicting famine as a result of population increase: The Population Bomb (1968); Population, resources, environment: issues in human ecology (1970, with Anne Erlich); The end of affluence (1974, with Anne Erlich); The population explosion (1990, with Anne Ehrlich). Ehrlich predicted, in the late 1960s, that hundreds of millions would die from a coming overpopulation-crisis in the 1970s, and that by 1980 inhabitants of the United States would have a life-expectancy of only 42 years. Erlich's predictions have as of 2009^[update] failed to come about. Other examples of applied Malthusianism include the 1972 book The Limits to Growth published by the Club of Rome, and the Global 2000 report to the then President of the United States of America Jimmy Carter. Science-fiction author Isaac Asimov issued many appeals for population-control reflecting the perspective articulated by people from Thomas Malthus through Paul R. Ehrlich.

More recently^[update], a school of "neo-Malthusian" scholars has begun to link population and economics to a third variable, political change and political violence, and to show how the variables interact. In the early 1980s, James Goldstone linked population variables to the English Revolution of 1640-1660^{[citation needed]} and David Lempert devised a model of demographics, economics, and political change in the multi-ethnic country of Mauritius. Goldstone has since modeled other revolutions by looking at demographics and economics{[fact}} and Lempert has explained Stalin's purges and the Russian Revolution of 1917 in terms of demographic factors that drive political economy. Ted Robert Gurr has also modeled political violence, such as in the Palestinian territories and in Rwanda/Congo (two of the world's regions of most rapidly-growing population) using similar variables in several comparative cases. These approaches suggest that political ideology follows demographic forces.

Malthus, sometimes regarded as the founding father of modern demography,^[62] continues to inspire and influence futuristic visions, such as those of K Eric Drexler relating to space advocacy and molecular nanotechnology. As Drexler put it in Engines of Creation (1986): "In a sense, opening space will burst our limits to growth, since we know of no end to the universe. Nevertheless, Malthus was essentially right."

The Malthusian growth model now bears Malthus's name. The logistic function of Pierre Francois Verhulst (1804-1849) results in the S-curve. Verhulst developed the logistic growth model favored by so many critics of the Malthusian growth model in 1838 only after reading Malthus's essay. Malthus has also inspired retired physics professor, Albert Bartlett, to lecture over 1,500 times on "Arithmetic, Population, and Energy", promoting sustainable living and explaining the mathematics of overpopulation.

• [Malthus] became the best-abused man of the age ^[63]
• There is hardly a cherished ideology, left or right, that is not brought into question by the principle of population. ^[64]

• Ebenezer Scrooge from A Christmas Carol by Charles Dickens, represents the perceived ideas of Malthus^{[citation needed]}, famously illustrated by his explanation as to why he refuses to donate to the poor and destitute: "If they would rather die they had better do it, and decrease the surplus population". (Although Dickens may have had some Malthusian concerns (evident in Hard Times and other novels), he concentrated his attacks on Utilitarianism and on those who preached the achievement of Utopia through work, with labour as the answer to all social ills.)
• In Robert A. Heinlein's novel, The Moon Is a Harsh Mistress, the character Bernardo de la Paz says to Mannie: "This planet isn't crowded; it is just mismanaged ... and the unkindest thing you can do for a hungry man is to give him food. Read Malthus. It is never safe to laugh at Dr. Malthus; he always has the last laugh."
• In Aldous Huxley's novel, Brave New World, people generally regard fertility as a nuisance, as cloning has enabled the society to maintain the population at precisely the level the controllers want. The women, therefore, carry contraceptives with them at all times in a "Malthusian belt".
• In John Fowles's The French Lieutenant's Woman Dr. Grogan' says of Malthus: "For him the tragedy of homo sapiens is that the least fit to survive breed the most".
• George R. R. Martin's novel Tuf Voyaging features a planet called S'uthlam (an anagram for "Malthus") which constantly faces the danger of mass famine because of its rapidly expanding population.
• Urinetown, a musical about a world torn by drought, ends with a shout of "Hail Malthus!" after explaining that all the characters in the show die. (The musical portrays a society that cannot sustain itself because of a scarcity of water due to over-consumption. As a result the citizens have to pay to urinate.)
• In the Season 1 finale of the television-series Sliders, "The Luck of the Draw" references Thomas Malthus.
• Bioy Casares's novel La invención de Morel makes frequent mention of Malthus
• The villanous Anti-Spirals from the television anime Tengen Toppa Gurren-Lagann represent Malthus's sociological theories taken to inhumane extremes.
• In the second season of the Stephen J. Cannell 1980's television series Wiseguy, the villainous character Mel Profit (played by Kevin Spacey) bases his arms-dealing philosophy on Malthus, saying: "The population grows geometrically and the food supply grows geographically. Three things keep the balance: Famine. Disease. And War."

[edit] Epitaph

The epitaph of Malthus in Bath Abbey reads:

Sacred to the memory of the Rev Thomas Robert Malthus, long known to the lettered world by his admirable writings on the social branches of political economy, particularly by his essay on population. One of the best men and truest philosophers of any age or country, raised by native dignity of mind above the misrepresentation of the ignorant and the neglect of the great, he lived a serene and happy life devoted to the pursuit and communication of truth. Supported by a calm but firm conviction of the usefulness of his labors. Content with the approbation of the wise and good. His writings will be a lasting monument of the extent and correctness of his understanding. The spotless integrity of his principles, the equity and candour of his nature, his sweetness of temper, urbanity of manners and tenderness of heart, his benevolence and his piety are still dearer recollections of his family and friends. Born February 14, 1766 Died December 29, 1834.
