Gersonides on Time and Eternity

Kreskis: Gersonides seems to have a very unusual view on this because he denies the eternity of the universe, as I understand it. On the other hand, he thinks that time is eternal and has been there since God came into existence. And so what he will want to argue is that the world itself is eternal in the sense that it's engendered out of what he calls a pre-existent matter. But at the same time, he wants to argue time is finite. So either the temporal sphere is not eternal, but was actually generated.
