"If the only ultimate check on the growth of population is misery, then the population will grow until it is miserable enough to stop its growth."
Second Theorem: "The Utterly Dismal Theorem"
This theorem "states that any technical improvement can only relieve misery for a while, for so long as misery is the only check on population, the [technical] improvement will enable population to grow, and will soon enable more people to live in misery than before. The final result of [technical] improvements, therefore, is to increase the equilibrium population which is to increase the total sum of human misery."
Third Theorem: "The moderately cheerful form of the Dismal Theorem"
"Fortunately, it is not too difficult to restate the Dismal Theorem in a moderately cheerful form, which states that if something else, other then misery and starvation, can be found which will keep a prosperous population in check, the population does not have to grow until it is miserable and starves, and it can be stably prosperous."
