There were two tendencies in ancient philosophy: according to the first one, our universe is unique (the Eleatics, Plato, Aristoteles), while according to the other, there are several universes, similar or totally dissimilar to ours (the Pythagoreans, the Atomists). Proponents of the first theory diverged in their opinion on the universe’s eternity though. Supporters of the second one argued over the similarity of another universes as well as the question if those universes co-exist or replace each other over time. These questions didn’t stop being actual in medieval Christian philosophy. But if there were no doubts about the question of an actual existence of our universe as being the only and unique, the question if God created only our universe was yet to be answered. St. Thomas Aquinas provides several evidences of the uniqueness of the universe – two from the ‘authority’ and three from himself.
