John Stuart Mill Population Quotations

The average condition of the people improving or deteriorating, depends upon whether population is advancing faster than improvement, or improvement than population.

A population may be too crowded, though all be amply supplied with food and raiment. It is not good for a man to be kept perforce at all times in the presence of his species...

If the earth must lose that great portion of its pleasantness which it owes to things that the unlimited increase of wealth and population would extirpate from it, for the mere purpose of enabling it to support a larger, but not a happier or a better population, I sincerely hope, for the sake of posterity, that they will be content to be stationary, long before necessity compels them to it.

A stationary condition of capital and population implies no stationary state of human improvement. There could be as much scope as ever for all kinds of mental culture, and moral and social progress.
