Explain the Cosmological Argument. (30 marks) One of the most famous proponents of the cosmological argument is the philosopher Thomas Aquinas who developed the Three Ways’ in his chief work, Summa Theologica in order to prove the existence of God based on the fact that there is a universe. He based his arguments on what he could observe in the world around him, which makes it an ‘a posteriori’ argument. Aquinas’ Three Ways that supported the cosmological argument are motion, cause and contingency. His First Way is based on motion, which, according to Aquinas, does not only include movement from one place to another but also the change of quantity and quality.

Since nothing can move itself, he concluded that there must be a Prime Mover, a so-called first mover, which itself was unmoved. This Unmoved Mover started off the chain of movement/motion, and to him the Prime Mover is God. To develop the argument further, he continued that objects or things only achieve their absolute potential through an external influence. As a result he also defined motion as potentiality turned into actuality.

Aquinas argued that nothing can be in potentiality and actuality at the same time or in other words, nothing can be simultaneously hot and cold, for example.
