Key passages
“The probability, therefore, is that each of those fixed stars is also a Sun, round which another system of worlds or planets, though too remote for us to discover, performs its revolutions, as our system of worlds does round our central Sun.”
It is likely that every fixed star is a sun with its own orbiting planets, just like our solar system.
Paine extends the heliocentric model to the entire universe, arguing for a plurality of worlds.
“By this easy progression of ideas, the immensity of space will appear to us to be filled with systems of worlds; and that no part of space lies at waste, any more than any part of our globe of earth and water is left unoccupied.”
This line of reasoning shows that space is filled with many systems of worlds, with no empty or wasted parts.
Paine emphasizes the purposeful and filled nature of the cosmos, reflecting deist design.
