"Must it not then be acknowledged by an attentive examiner of the histories of mankind, that in every age and in every State in which man has existed, or does now exist

That the increase of population is necessarily limited by the means of subsistence,

That population does invariably increase when the means of subsistence increase, and,

That the superior power of population is repressed, and the actual population kept equal to the means of subsistence, by misery and vice."
