The inhabitants of the planet Jupiter saw that I had thought about the number of people or souls, if there were a thousand planets filled with inhabitants, such as our earth, over a period of 6000 years. I then figured for them that the populace of a thousand planets over 6000 years would not fill the space that their planet appears to us to contain. Taking one generation as 35 years, in 6000 years 171 3/7 generations would arise from it. Therefore, if the people living today on this earth multiplied 171 3/7 times, they would not fill up a thousandth part of the surface of that planet. And then if the space to the center of the planet were counted as living-space, one might conclude that if there were thousands of planets, even tens of thousands, in the universe, then to our eyes, a globe of so many tens of thousands would not appear as large as the globe of their earth. Yet still it is such a small quantity as to be almost nothing compared to the universe. Moreover, if the universe were filled [with people] from one end to the other, [their number] would still be as nothing to the infinite Lord. 1748, 1 March.
