"All we can say now is, that, even now, 600 persons could easily live on a square mile; and that … 1,000 human beings—not idlers—living on 1,000 acres could easily, without … overwork, obtain … a luxurious vegetable and animal food, as well as the flax, wool, silk and hides necessary for their clothing. As to what may be obtained under still more perfect methods—also known but not yet tested on a large scale—is better to abstain from any forecast: so unexpected are the recent achievements of intensive culture. We thus see that the over-population fallacy does not stand the very first attempt at submitting it to a closer examination."
