St. Thomas Aquinas’ First Two Ways in Proving the Existence of God

It is my view that God exists, and I think that Aquinas’ first two ways presents a

successful argument for the existence of God. No doubt, the arguments have weak points

which are subjected to criticism but nonetheless, in my opinion, these propositions by

Aquinas do indeed accomplish their purpose in establishing the existence of a Greatest

Conceivable Being that is the unmoved mover and uncaused cause. I believe that this

ultimate Being is unchanging and started the universe, time and all matter and concepts

of existence. In my view, this Being is what we understand to be God.

St. Thomas Aquinas recognized that there were some people who doubted the

existence of God because, to them, logic did not allow for or explain God’s existence. His

first two ways are two proofs based on logic and observation of nature in proving God’s

existence to those who could not accept or believe God on faith alone. Aquinas’ first way

is based on motion. He calls it the most obvious way. This first argument, the Argument

from Motion, tries to prove the existence of God as the first mover which is unmoved.

and if something is in motion, then it must be caused to be in motion by something
