After the Fourth Lateran Council in 1215 settled the question in the West whether or not the world exists from eternity, a new debate arose concerning the demonstrability of the temporal creation of the world. Thomas Aquinas, of course, also joined in the controversy, and while accepting on faith the constitution of the council, argued for the logical possibility of the eternity of the world. In doing so, he had to refute all the counter-arguments provided against the possibility of an eternally created world.
