Quote by Thomas Malthus
"I think I may fairly make two postulata. First, that food is necessary to the existence of man. Secondly, that the passion between the sexes is necessary and will remain nearly in its present state."
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."
