Aquinas and Searching for God and His Relationship with the World

Saint Thomas Aquinas was a Philosopher used the logic of both Aristotle and Saint Augustine to establish his teachings. He taught that believing in God was not simply for the ignorant. He used both Greek Philosophy and Christian Doctrine in his teachings. He taught an abundant of things including that the goal of Theology is is use reason to grasp the truth about God and to experience salvation through that truth. In addition to that, he shaped the catholic understanding of mortal sin and venial sin.

Aquinas argued the existence of God with five main points. Aquinas began by saying that nothing can be a cause of itself; rather every event was caused by some prior event. Therefore event A causes event B that leads to event C and so forth. He believed in this cause and effect relationship but believed that there must be a first cause as a starting point. When contemplating this starting point Aquinas rejected the possibility of an infinite series of events. This means that the universe has not existed forever and there must have been something from which every single event stems. There must be an uncaused first cause, which Aquinas concluded to be God. The first cause is called the unmoved mover. The unmoved mover is what set all other events and beings in motion.

     Aquinas’ third way argument states that there has to be something that must exist, which is most likely God. He starts his argument by saying not everything must exist, because things are born and die every single day. By stating this we can jump to the conclusion that if everything need not exist then there would have been a time where there was nothing. But, he goes on, if there was a time when there was nothing, then nothing would exist even today, because something cannot come from nothing. However, our observations tell us that something does exist, therefore there is something that must exist, and Aquinas says that something is God.

To prevent the possible hypothetical problem of infinite regression, Aquinas believes in an unmoved mover. Based on the foundations of Aristotle’s God the unmoved mover who thinks about nothing but himself as in thinking about other things would cause movement and contradict his state of unmovement. In the same way, Aquinas adopts the same model of an unmoved god who first puts other things in motion. However, unlike Aristotle, Aquinas merely adopts the idea of contingency to postulate a non-antideity. From the bases of causation and motion we arrive at two attributes of God ‘unmoved mover’ and ‘uncaused first cause’. with motion, “nothing else than the reduction of something from potentiality to actuality” therefore cannot be simultaneously in actuality and

Aquinas sets up this argument in his discussion of whether or not God exists. His five proofs set up the framework for much of his later writings in the Summa

Several hundred years ago, two great philosophers Thomas Aquinas’s and Rene Descartes used the method of ontological argument for the existence of God and used intuition and reason alone to get to each other’s theory. Rene Descartes wrote out several mediations, but the one we’re going to touch base on is meditation III that he wrote in the 1600’s; While Thomas Aquinas’s wrote his five proofs of God in 1270 that specifies God’s existence in each proof; the one that gives the best argument is the existence of God in his III proof. While both philosophers provide great information about their reason about God, Thomas Aquinas’s and Rene Descartes both attempt to prove the existence of God, but

Well unfortunately some believe their (omnipotent) God has all the answers and knows of every person’s next moves and what’s yet to come. I can somewhat agree with that but I don’t believe it is my duty to judge or prove the existence, and the all mighty power God has. I certainly am a believer of faith and that the existence of good and evil lies in all of us, regardless of the control God has over us. My opinion relates to how Aquinas believes that everyone’s consequences and endings they choose are because of the free choice God gives us all. As mentioned in the book, a great example that I find makes a perfect analogy is when he states, “He can create in a multitude of ways, No

Thomas Aquinas’ five ways are his arguments of the five proofs that God exists in some form, these five ways have standard abjections. The arguments are named as follows: argument from motion, arguments from causation, arguments from contingency, argument from gradations of goodness, and the argument of governance. These are Aquinas’ theories of why things change, whatever is changing is being changed by something else.

Therefore, it is more believable that the universe had a beginning and a personal creator. The third of Aquinas' ways is the argument of contingency. The world consists of contingent items- items that have a property are items referred to as 'being.' These items are generated and perish; they have a beginning and an end.

The first part in which one can prove that there is a God is based on change. In the first part, Aquinas mentions that things change and that there has to be something which brings about that change, but at the same time is changeless. Aquinas states that “a thing in process of change cannot itself cause that same change; it cannot change itself” (Aquinas 45). For example, he gives an example about wood and fire. The wood is able to be hot but simply cannot make itself change without having an outside source that will cause it to become hot. The fire, that is naturally hot, will indeed make the wood hot and as a result, will change the wood.

Aquinas argues that all things that are in motion must be moved to actuality by something that has already been actualized. This is because something cannot be in potency and

Aquinas' second proof is similar to his first in that it relates to cause and effect. St. Thomas reasoned that in a world of order there is an order to all cause and effect. And , since there is a cause for the existence of all things there must be a cause that caused all things and had no cause itself. He points out that nothing in creation existed prior to itself and the causality cannot be traced back infinitely. If the efficient or first cause did not exist then nothing would exist. That first or efficient cause is God.

5.) Aquinas explains that a person cannot have knowledge of a corporeal thing unless that person has the sense in order to have a sensory experience of it. This experience that is explained by Aquinas is the first of his three grades of cognitive power. He calls his first grade of cognitive power the sense, being the act of a bodily organ in order to understand the individuals and their particulars. The second grade of cognitive power he calls the angelic intellect which exists apart from matter. He explains the angelic intellect as a divine mind in which knows the universal and understands the material things through immaterial things. The final grade of cognitive power is the human intellect and Aquinas explains that

The Medieval Era was a time dominated by belief. People lived with such great superstition and fear of God. Many people were focused not on their lives her on earth, but rather their life after death. During the Renaissance people became more humanistic and focused more on their lives in the moment rather than their afterlife. We can see these changes of Ideas by studying the works of Saint Anselm of Canterbury, Saint Thomas Aquinas, Thomas a Kempis, and Caesarius of Heisterbach from the Medieval Era and compare it to the works of Marsilio Ficino, Leonardo Da Vinci, Niccolo Machiavelli, and Desiderius Erasmus of the Renaissance period we can see

St. Thomas Aquinas is a famous philosopher from the medieval period who believed there was a god. One of Aquinas significant works in philosophy was his argument that God exists. In Aquinas' argument, or also known as Summa Theologica, he uses five arguments to support the claim that God exist and four of them are cosmological argument. Cosmological arguments are arguments that try to reason that god exists because of the universe or cosmos leads to the conclusion that god exists. His first argument is the Argument From Motion. In the argument of motion Aquinas observed that we live in a world and universe that things are continuously moving, and he also noticed that to make something move something has to move or start it moving. To Aquinas this means that everything that is moving must have been moved by something or someone and there had to be a time when the thing wasn't moving. The mover for the beginning of everything in Aquinas' argument is God. The second argument is the Argument From Causation which is very similar to the Argument From Motion. Aquinas thoughts were that everything that is caused had to be caused by something else. Nothing can cause it's self so there must be an thing that is uncaused and to Aquinas that thing is God because it can't go back forever. The Third argument is The Argument From Contingency. Contingency is a future or thing that could have not existed and Aquinas believe that the world can't always be contingent because then it could have
