The Man of Forty Crowns: I have heard much talk of population. Were we to take it into our heads to beget double the number of children we now do; were our country doubly peopled, so that we had forty millions of inhabitants instead of twenty, what would happen?

The Geometrician: Each would have, instead of forty, but twenty crowns to live upon; or the land would have to produce the double of what it now does; or there would be the double of the nation’s industry, or of gain from foreign countries; or one half of the nation sent to America; or the one half of the nation should eat the other.—The Man of Forty Crowns.
