In the “Suma Theologica,” by Saint Thomas Aquinas, Aquinas combines the doctrines of Christianity with Aristotelian philosophy, through the assertion that as a result of observation, utilization of the senses, and an empirical mindset, one can substantiate the existence of God. Aquinas holds the conception that in the quest for God’s existence, philosophy and theology are interwoven together and both play complementary roles. He infuses numerous theological doctrines, mainly from Saint Augustine, alongside Aristotelian ideals such as, the first mover, to corroborate his argument for the existence of God. Instead of basing his argument on human reason and rationality like his predecessor, Saint Anselm of Canterbury, Aquinas holds that it is …show more content…

As a result, it is impossible for an object to dwell in a state of both actuality and potentiality, therefore, “whatever is moved must be moved by another,” that is it should move itself (Aquinas 25). From this, Aquinas draws the conclusion that an infinite regress is impossible because there is no beginning and no end and therefore there would be no first mover or no other subsequent movers. Since there is motion, there must be a mover who is able to move things, but does not have to be moved itself. Thus, something must exist for which its nature is out of necessity and that is God, the first mover made up of pure actuality.

If one were to eliminate the work done by the painter, there would be no
