Quote by Thomas Malthus
"The passion between the sexes has appeared in every age to be so nearly the same that it may always be considered, in algebraic language, as a given quantity."
More from Thomas Malthus
"The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race."
"Population, when unchecked, increases in a geometrical ratio."
"The means of subsistence increase in an arithmetical ratio."
"That the increase of population is necessarily limited by the means of subsistence."
