So states Parent Duchatelet in his work on "Prostitution." From all the information which I have been able to gather, I find that all the remedies for pauperism and fecundity--sanctioned by universal practice, philosophy, political economy, and the latest reformers--may be summed up in the following list: masturbation, onanism, [19] sodomy, tribadie, polyandry, [20] prostitution, castration, continence, abortion, and infanticide.

[21] All these methods being proved inadequate, there remains proscription.
Unfortunately, proscription, while decreasing the number of the poor, increases their proportion.

If the interest charged by the proprietor upon the product is equal only to one-twentieth of the product (by law it is equal to one-twentieth of the capital), it follows that twenty laborers produce for nineteen only; because there is one among them, called proprietor, who eats the share of two.

Suppose that the twentieth laborer--the poor one--is killed: the production of the following year will be diminished one-twentieth; consequently the nineteenth will have to yield his portion, and perish.

For, since it is not one-twentieth of the product of nineteen which must be paid to the proprietor, but one-twentieth of the product of twenty (see third proposition), each surviving laborer must sacrifice one-twentieth PLUS one four-hundredth of his product; in other words, one man out of nineteen must be killed.
Therefore, while property exists, the more poor people we kill, the more there are born in proportion.
Malthus, who proved so clearly that population increases in geometrical progression, while production increases only in arithmetical progression, did not notice this PAUPERIZING power of property.
