and to be administered in the most perfect manner, after whatever model we suppose it to have been framed, such a perfect form would be so far from lasting for ever, that it must come to an end so much the sooner on account of its perfection. For, though happily such Governments should be firmly established—though they should be found consistent with the reigning passions of human nature, though they should spread far and wide—nay, though they should prevail universally, they must at last involve mankind in the deepest perplexity, and in universal confusion. For how excellent soever they may be in their own nature, they are altogether inconsistent with the present frame of nature, and with a limited extent of earth.
"Under a perfect Government, the inconveniences of having a family would be so entirely removed, children would be so well taken care of, and every thing become so favourable to populousness, that though some sickly seasons or dreadful plagues in particular climates might cut off multitudes, yet in general, mankind would increase so prodigiously, that the earth would at last be overstocked, and become unable to support its numerous inhabitants.
"How long the earth, with the best culture of which it is capable from human genius and industry, might be able to nourish its perpetually increasing inhabitants, is as impossible as it is unnecessary to be determined. It is not probable that it could have supported them during so long a period as since the creation of Adam. But whatever may be supposed of the length of this period, of necessity it must be granted, that the earth could not nourish them for ever, unless either its fertility could be continually augmented, or by some secret in nature, like what certain enthusiasts have expected from the philosopher's stone, some wise adept in the occult sciences should invent a method of supporting mankind quite different from any thing known at present. Nay, though some extraordinary method of supporting them might possibly be found out, yet if there was no bound to the increase of mankind, which would be the case under a perfect
