Industrial wealth has grown at a rate which no possible increase of population could attain, and it can grow with still greater speed. But agriculture is still considered a stronghold of the Malthusian pseudophilosophy. The recent achievements of agriculture and are not sufficiently well known; and while our gardeners defy climate and latitude, acclimatise sub-tropical plants, raise several crops a year instead of one, and themselves make the soil they want for each special culture, the economists nevertheless continue saying that the surface of the soil is limited, and still more its productive powers; they still maintain that population which should double each thirty years would soon be confronted by a lack of the necessities of life!

In short, we may say that the theory of Malthus, by shaping into a pseudo-scientific form the secret desires of the wealth-possessing classes, became the foundation of a whole system of practical philosophy, which permeates the minds of both the educated and uneducated, and reacts, (as practical philosophy always does) upon the theoretical philosophy of our century.

Science, down to the present day, remains permeated with Malthus's teachings. Political economy continues to base its reasoning upon a tacit admission of the impossibility of rapidly increasing the productive powers of a nation, and of thus giving satisfaction to all wants. This postulate stands, undiscussed, in the background of whatever political economy, classical or socialist, has to say about exchange-value, wages, sale of labour force, rent, exchange and consumption. Political economy never rises above the hypothesis of a limited and insufficient supply of the necessities of life; it takes it for granted. And all theories connected with political economy retain the same erroneous principle. Nearly all socialists too, admit the postulate. Nay, even in biology (so deeply interwoven now with sociology) we have recently seen the theory of variability of species borrowing a quite unexpected support from its having been connected by Darwin and Wallace with Malthus's fundamental idea, that the natural resources must inevitably fail to supply the means of existence for the rapidly multiplying animals and plants.

As to the poorer classes—who always feel the influence of ideas circulating at a given time amid the wealthier classes—it deprived them of the very hope of improvement; it made them skeptical as to the promises of the social reformers; and to this day the most advanced reformers entertain doubts as to the possibility of satisfying the needs of all; in case there should be a claim for their satisfaction, and a temporary welfare of the labourers resulted in a sudden increase in population.

He thus gave to the rich a kind of scientific argument against the ideas of equality; and we know that all dominion is based upon force, force itself begins to totter as soon as is no longer supported by a firm belief in its own rightfulness.

Few books have exercised so pernicious an influence upon the general development of economic thought as Malthus's Essay on the Principle of Population exercised for three consecutive generations. It appeared at the right time, like all books which have had any influence... and it summed up the ideas already current in the minds of the wealth-possessing minority. It was precisely when the ideas of equality and liberty, awakened by the French and American revolutions, were still permeating in the minds of the poor, while the richer classes had become tired of their amateur excursions into the same domains, that Malthus came to assert, in reply to Godwin, that no equality is possible; that the poverty of the many is not due to institutions, but is a natural law... and that law cannot be changed by any change of institutions.

Those who can be horror-stricken at seeing the population of this country increase by one... every 1,000 seconds who think of a human being as a mere claimant upon the material wealth of mankind, without being at the same time a contributor to that stock. But we, who see in each newborn babe a future worker capable of producing much more than his own share of the common stock—we greet his appearance.

We thus see that the over-population fallacy does not stand the very first attempt at submitting it to a closer examination.

All we can say now is, that, even now, 600 persons could easily live on a square mile; and that... 1,000 human beings—not idlers—living on 1,000 acres could easily, without... overwork, obtain... a luxurious vegetable and animal food, as well as the , wool, silk and hides necessary for their clothing. As to what may be obtained under still more perfect methods—also known but not yet tested on a large scale—is better to abstain from any forecast: so unexpected are the recent achievements of intensive culture.

If we take all into consideration; if we realise the progress made in the gardening culture, and the tendency towards spreading its methods... if we watch the cultural experiments which are being made now—experiments today and realities tomorrow—and ponder over the resources kept in store by science, we are bound to say that it is utterly impossible to foresee at the present moment the limits as to the maximum number of human beings who could draw their means of subsistence from a given area of land, or as to what a variety of produce they could advantageously grow in any latitude.
