Weak Arguments in Cosmological Argument by Thomas Aquinas

St. Thomas Aquinas’s first cosmological argument, the prime mover, defines things in the world as being either in a state of potentiality or in a state of actuality. Those things that are in potentiality are things that have the capability of being reduced to another form. Such as a boy is potentially a man, or tree is potentially a house. Things that are in a state of actuality are things that are currently reaching their potential; such as that boy becoming a man, or that tree becoming that house. Aquinas observed that all things in a state of actuality had to have been put into that state by something that was already in actuality. In thinking about this he concluded that there would have to be an infinite regress of actual things making potential things actual. He concluded that this would be impossible because given that, there would be no first mover. He instead, postulated that there must be a first mover. A being that never had potential but only has existed in a state of infinite actuality. That what we call God.

Comparing Aquinas and Descartes they both in a way have arguments for cause in proving the existence of God. Aquinas in that "nor indeed it is possible, that anything is the efficient cause of itself" (The Second Way, 2) and there needs to be a first cause that is the cause of all

- St. Thomas Aquina interpreted Aristotelian philosophy from a Christian perspective. Aquina also gave five proofs for God’s existence; motion, efficient cause, possibility and necessity, degrees of perfection and design. The first way was natural things are in motion. If something is in motion, then it must be set into motion by something outside of itself. There

The ideas that God is altogether simple and that he has complete knowledge of himself and all things form the foundation for much of Aquinas' arguments for the existence of a world of contingent beings, deriving from a necessary being. Aquinas continues this line of reasoning in his argument that God's knowledge is the cause of things. Aquinas likens this relationship to the artificer and the art. The artificer, working through his intellect, creates the art. As Aquinas says, "Hence the form in the intellect must be the principle of action." Aquinas also says, "Now it is manifest that God causes things by his intellect, since his being is his act of understanding; and hence his knowledge must be the cause of things, insofar as his will is joined to it." Aquinas is saying here that if God's intellect creates things, i.e. human beings, then he must also be the cause of those things because his intellect is the same thing as his will. Keeping in mind that God is altogether simple, this conclusion naturally follows a logical sense of reasoning.

Aquinas’ first and second argument are both very similar to one another. Aquinas states “To cause change is just to draw something out of potentiality into actuality” (Aquinas 43). So here, Aquinas is saying that something has the potential to change. And if you change it that makes it a reality. Aquinas then states “this can only be done by something in actuality.” (Aquinas 43). This something that he is referring to is God. Next Aquinas states “It is therefore impossible for a thing that undergoes a change to cause that change, or for something to change itself. Therefore, whatever undergoes change must be changed by another thing. And, if this other thing undergoes change, it also must be changed by something else, and so on.” (Aquinas 43). However, Aquinas goes back on what he has said and states “But this cannot go back to infinity” (Aquinas 43). This is what we called an “infinite regress”. However, I am not a fan of Aquinas’ theory that an infinite regress is impossible. While it’s understandable, I believe that us as humans will always ask “why?” So we can follow Aquinas and say that an infinite regress is impossible and we must stop at God. But, this brings the questions of “why is God exempt from this?” and if we choose to not follow Aquinas and believe an infinite regress is possible then we can go back into infinity which dismantles 3 of his 5 arguments. After all, he is trying to prove the existence of only one God. Aquinas then wraps up his first argument by saying “We must therefore posit a first cause of change which is not itself changed by anything. And this everyone understands to be God.” (Aquinas 43).

The Strengths and Weaknesses of the Cosmological Argument for the Existence of God The cosmological argument seeks to prove the existence of God by looking at the universe. It is an A posteriori proof based on experience and the observation of the world not logic so the outcome is probable or possible not definite. The argument is in three forms; motion, causation and being. These are also the first three ways in the five ways presented by Aquinas through which he believed the existence of God could be shown.

Aquinas ' second argument is that there are many things that happen in this world, and that these occurrences are effects derived from a cause. The effects in turn can be the cause of something else and so on and so on. Nothing, however, can be the cause of itself, so there must be a first efficient cause that sets off other intermediate causes, in hopes of reaching an ultimate goal. Therefore, according to Aquinas, the first of all the efficient causes would be God.

Thomas Aquinas is one of the Christian and Catholic churches most beloved philosophers and theologians. Throughout his 49-year lifespan, Aquinas combined the theological ideologies of religion with the logical concepts of reason. He did this most notably through his publication of the Five Ways, also known as the Five Proofs, which were written in his book Summa Theologica. In his Five Ways, Aquinas takes the cosmological approach to the argument over God’s existence. That is, each proof begins with an observation about the universe and connects the observations to the dependency of nature. For some action to occur, another action must push it into occurrence. For example, a ball cannot move from rest without an outside force acting on it. This links to the idea of God in that he is argued to be the outside force that initiated the universes existence. Aquinas breaks this argument down into the Arguments from Motion, Causation, Contingency, Degree, and the Teleological argument. Within this analysis, Aquinas’ Argument from Motion will be broken down into its parts, premises and conclusions, and criticisms countering his argument will be offered and explained.

Aquinas arguments are strong cases in the existence of God. His work helped me appreciate and made me want to explore his philosophical skill in exploring Gods nature, and also defending Christian teaching. Being Christian is one of the main reasons why I picked Aquinas arguments, also because the work he provided for us is true in my eyes. I’m going to defend and state some reasons in why I believe him and his role should be played in Religion today. “Motion” an argument he tries to prove in God existence.

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' 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.

Aquinas says we experience causality Nothing is the cause of itself causes are other than their effects. There cannot be an infinite regress of caused causes. If there were an infinite regress, the effects we experience here & now would not exist. Therefore, there must be some first cause and this we call "God." There is also the law of argument by design, we naturally work towards a goal, we also lack the knowing of the outcome, but we reach our goal by being pointed in the direction, therefore there is an intelligent being pointing us in the direction and that would be proof of “God”.

Thomas Aquinas theorized five different logical arguments to prove the existence of God utilizing scientific hypotheses and basic assumptions of nature. In the fifth of his famous “Five Ways”, Aquinas sets forth the assumption that all natural bodies move toward an end. Since bodies are constantly moving in the best way possible to achieve that end, the path must be designed. God, of course, is the ultimate designer of the universe.

Here Aquinas argues that everything that happens is the cause of something, but nothing can cause itself. If we trace back a cause all the way back to the beginning of the world, it could not have caused itself. Therefore, God must have been the first cause. Aquinas’ third proof is the Argument from Contingency. We see that everything here on earth is finite. People die, empires fall. All things must come to an end. That means things had to have a beginning where nothing was in existence yet. How did things come into existence? God. Aquinas’s 4th argument is the Argument of Degrees. Here we judge things to be a certain degree of good or bad. But what are we comparing that to? If they have a certain degree of good and bad, then what is the greatest degree of good? And that must be God. Aquinas’s final argument is his Argument from Design. Perhaps one of his strongest arguments Aquinas says that there must be an intelligent designer behind everything. Random objects don’t have any brains to act the way they do. But they are directed in the way they act by God.

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
