Thomas r malthus an essay on the principle of population

If he should succeed in drawing the attention of more able men, to what he conceives to be the principal difficulty in the way to the improvement of society, and should, in consequence, see this difficulty removed, even in theory, he will gladly retract his present opinions and rejoice in a conviction of his error.

Table of Contents. FIRST Preface The following Essay owes its origin to a conversation with a friend, on the subject of Mr. June 7, Although it was simultaneously discovered by Torrens , West and Ricardo , Malthus's pamphlet was the first of the four to be published. Refuting older contentions that rent was a cost of production, Malthus argued that it was merely a deduction from the surplus. Rent, Malthus argued, is enabled by three facts: 1 that agricultural production yields a surplus; 2 that the wage-fertility dynamics guarantee that the price of corn would remains steadily above its cost of production; 3 that fertile land is scarce.

Ricardo own essay was actually a response to Malthus. Ricardo dismissed Malthus's arguments, arguing that Malthus's "third" cause -- that land differs in quality and is limited in quantity -- is sufficient to explain the phenomenon of rent. He incorporated Malthus's theory of rent with his own theory of profits to provide the " Classical " statement of the theory of distribution. He also dismissed Malthus's feeble attempts to defend parasitical landlords and the Corn Laws. Malthus's own criticism of Ricardo's essay led them into a debate on the question of "value".

Malthus supported Smith's old "labor-commanded" theory of value, whereas Ricardo favored the "labor-embodied" version. The outcome of the discussion was Ricardo 's Principles in , which set down the doctrine of the Classical School on value, distribution and production, incorporating at least two of Malthus's own contributions: the "natural wage" version of Malthus's population theory and an expanded version of Malthus's theory of rent.

Malthus was never comfortable as a member of the Classical school. Nowhere is this more evident than in Malthus's own treatise, Principles of Economics He differs from the Classical Ricardians at several points. For instance, Malthus introduced the idea of a demand schedule in the modern sense, i.

He also paid much attention to the short-run stability of prices. Thirdly, and most famously, Malthus denied the validity of Say's Law and argued that there could be a "general glut" of goods. Malthus believed that economic crises were characterized by a general excess supply caused by insufficient consumption. His defense of the Corn Laws rested partly on the need for landlord consumption to "make up" for shortfalls in demand and thus avert crisis. See our more extensive discussion of the General Glut Controversy. Alphabetical Index. No limits whatever are placed to the productions of the earth; they may increase for ever and be greater than any assignable quantity, yet still the power of population being a power of a superior order, the increase of the human species can only be kept commensurate to the increase of the means of subsistence by the constant operation of the strong law of necessity acting as a check upon the greater power It makes no difference how much productivity increases, Malthus writes, it could not long keep up with unrestrained reproduction.

Population must be constantly checked to keep it in line with what the earth can produce. It is not nearly so high 7 billion as of this writing because there have been constant checks on population in the last years.

Thomas Robert Malthus

While food productivity has increased substantially, it has not nor could it increase at the same rate as unchecked population growth. What are these checks that Malthus writes about? They include celibacy, contraception, and various forms of non-procreative sex. Under this heading Malthus includes extreme poverty, diseases, plague, malnutrition, wars, infanticide, and famine.

Positive checks are far more likely to operate within poor populations; preventive checks among the upper classes. As the food supply increases, food becomes cheaper, and more children are brought into the world.

As there are more mouths to feed, food becomes more expensive, thus causing stress on families, more children dying or steps taken to prevent conception itself. As food prices rise, more land is put under the plow, or greater efforts made in intensifying the production of the land itself. While Malthus recognized that the relationships among the fertility of people and land are a good deal more complex than this simplified assertion, he maintained there is a recurrent reciprocal relationship between the two.

Because of this reciprocal relationship between population and production, over the course of sociocultural evolution, both population and food production have grown in tandem. Periods of increase in food productivity, whether because of the application of technology or the expansion of cultivated land, have been met with expansions of population. Periods of stability in food production, or contraction in productivity, have been marked by the same phenomena in population level. Because people can reproduce faster than they can increase the production of food, population must always be checked through positive or preventive means.
