Overview[ edit ] Between and Malthus published six editions of his famous treatise, 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 first points out that human nature being what it is, the passion between the sexes appears to be fairly constant and, if unchecked population will double itself every twenty-five years. 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.
Because of this unequal power between production and reproduction, "population must always be kept down to the level of the means of subsistence.
Here is the key to that riddle: Malthus made the mistake of illustrating the unequal powers of production and reproduction with a mathematical illustration.

Agricultural production at best, he argues, could not possibly keep pace. But to make the argument more general and less interrupted by the partial views of emigration, let us take the whole earth, instead of one spot, and suppose that the restraints to population were universally removed.
If the subsistence for man that the earth affords was to be increased every twenty-five years by a quantity equal to what the whole world at present produces, this would allow the power of production in the earth to be absolutely unlimited, and its ratio of increase much greater than we can conceive that any possible exertions of mankind could make it.
Taking the population of the world at any number, a thousand millions, for instance, the human species would increase in the ratio of—1, 2, 4, 8, 16, 32, 64,etc. In two centuries and a quarter, the population would be to the means of subsistence as to At one point in the Essay he even states: But for various reasons many critics have taken this mental experiment as the theory of population itself and delight in writing that Malthus was wrong, that overshoot and collapse did not occur.
Contrary to popular belief and the belief of many who should know betterMalthus did not predict a future in which population would outrun food supply and eventually collapse.
Other critics write that Malthus was wrong because he did not take into account the possibility of dramatic increases in the production of food.
Many criticize him for not taking into account the revolution in agriculture. But he anticipated this argument as well: 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.
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 are of two types: 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.Study Guide for An Essay on the Principle of Population.
