Politics
Context: One would have thought that it was even more necessary to limit population than property; and that the limit should be fixed by calculating the chances of mortality in the children, and of sterility in married persons. The neglect of this subject, which in existing states is so common, is a never-failing cause of poverty among the citizens; and poverty is the parent of revolution and crime.

“Poverty puts crime at a discount.”
La pauvreté met le crime au rabais.
Maximes et Pensées (Van Bever, Paris :1923), #312
Reflections; alternately translated as: "Poverty sets a reduced price on crime"; in The Viking Book of Aphorisms (1962).

“The evils of poverty are not barren, but procreative”
Source: Poverty (1912), p. v
Context: The evils of poverty are not barren, but procreative, and... the workers in poverty, are in spite of themselves, giving to the world a litter of miserables, whose degeneracy is so stubborn and fixed that reclamation is almost impossible, especially when the only process of reclamation must consist in trying to force the pauper, vagrant, and weakling back into that struggle with poverty which is all of the time defeating stronger and better natures than theirs.
