St. Thomas Aquinas presents five arguments to demonstrate the existence of God. However, this paper focuses on the fifth argument. The fifth argument is regarded as the Teleological Argument and states that things that lack intelligence act for some end or purpose. While the fifth argument satisfies God’s existence for Aquinas, some contemporary readers would argue that Aquinas neglects the laws of physics. Others argue that Aquinas allows a loophole in his argument so that the Catholic conception of God is not the only intelligent designer. Aquinas has several premises that all his arguments rely on. The starting point is that dependent beings exist. Since they exist, they (including their essence or characteristics) must have a cause. It …show more content…

A thing cannot move towards its end without an intelligent being directing the thing to its end. The intelligent being that moves all natural things toward their end is God. Therefore, things that lack intelligence do not obtain their end or purpose by random chance, but by God. In other words, things have order or regularity. Aquinas says that “this is clear from the fact that they always, or usually act in the same way so as to achieve what is best” (Aquinas 26). It then follows that since things have order, they must be goal oriented. Aquinas is saying that the course of actions that unintelligible beings have are directed by …show more content…

A contemporary reader would argue that Aquinas neglects that the laws of physics and nature can exist beyond a creator. Even though the world is complex, a creator does not necessarily have to exist. For example, in Aquinas’ example in the text, the archer applied force in order move the arrow. This would follow Newton’s laws of motion and these principles are things that people can not violate because they are always true. Therefore, the intelligent being himself moved the arrow, but that the law of physics was also involved to get the arrow to its end. Another problem is in Aquinas statement that things “reach their goal by purpose, not by chance” (Aquinas 26). However, how do we know that the world does not have randomness or chance? Actually, there are some examples in science that debunks Aquinas’ statement. For example, Richard Dawkins believed that random mutations in species allows for variation and a bigger genetic pool in support of Darwin’s theory of evolution. Lastly, Aquinas claims that the designer has to be God because He is an uncaused cause. Even if people accepted this, Aquinas does not substantiate why it must be the case that the Catholic conception of the one and only true God is the only intelligent designer of all natural things. Aquinas leaves room for polytheism to exist, and hence more than one intelligent designer can move material things. If this is the
