Thomas Aquinas presents two different argument for the existence of a God based on the “government” of things, one in the Summer contra Gentiles and one in the Summa Theologiae, the latter the so-called “Fifth way”. First, I argue that the Fifth way is metaphysically more fundmental, for which reason it is selected for use in the later Summa. Secondly, I address the question of the argument's validity, alling attention to its foundation in absolutely fundamental experience.
