In the last chapter of De immortalitate animae, Pomponazzi claims that the question of immortality, just like the question of the eternity of the world, is a neutral problem. In this paper I claim that Pomponazzi has usually considered the aeternitas mundi as a probable proposition in the Aristotelian sense, rather than as a problem. Furthermore, I evaluate some analyses that use the former issues (among others) to interpret Pomponazzi’s thought.
