For Volume IV of his Philosophical Dictionary, Voltaire wrote an entry for ‘End of the World’.
The greater part of the Greek philosophers held the universe to be eternal both with respect to commencement and duration. But as to this petty portion of the world or universe, this globe of stone and earth and water, of minerals and vapors, which we inhabit, it was somewhat difficult to form an opinion; it was, however, deemed very destructible. It was even said that it had been destroyed more than once, and would be destroyed again.
Let this set you free, writer. The end of the world will come again, and then again. Let it come. Hasten it with your words if you dare.
