Aquinas Five Proofs

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.

     There is, however, a way to fix Aquinas’ theory. If we take his logic into account we can say that there was a time when the universe did not exist. But, the universe exists now therefore it must have had a beginning. By definition a necessary being has no beginning and now end. Due to this definition we can say that the universe is not a necessary being. This leaves us with one of three options: there is a necessary being, the universe has always existed, or something can come into existence out of nothing. Due to the big bang theory we can eliminate the theory of the universe always existing. Therefore, there is a necessary being or something can come into existence out of nothing. Because we know that something cannot come into existence out of nothing we determine that there must be a necessary being. However, the necessary being is either God or the universe. Because the universe had a beginning it can not be necessary, therefore God is the necessary being and he must exist.

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.

The central problem of this paper that I am going to try to convince my atheist friend is that god existed. I will argue in favor of a higher being by first presenting and evaluating two argument that will be used to persuade my atheist friend. First I will explain Pascal’s argument. Second I will explain one of the arguments of Aquinas’s that is in favor of the existence of god. Then I am going to explain what’s the central difference between the two arguments is. I will conclude by stating whether I was successful in converting my atheist friend.

As discussed in class, modern scientific research provides alternatives to Aquinas’s presumed necessities. An infinite series of causes no longer seems impossible. This research disproves Aquinas 's third premise (P3), and his argument for God as the first cause is consequently unnecessary. Furthermore, the fourth premise still has a logical gap between the first cause and God. Aquinas offers no explanation as to why the first cause must be God or a supernatural being at all. The first cause may just as easily be a spontaneous event, or a first cause may not exist at all in an infinite universal cycle.

Thomas Aquinas’ five ways prove that God exists in some form, his argument that God exists through motion is a sound theory that he created. There are objections

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.

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.

As one of most valuable works on this topic one can name St. Thomas Aquinas' Summa Theologiae, in which he states that existence of God, can be demonstrated in five different ways.

He believed in natural theology and thought that man could not understand God without God's assistance and guidance. The foundations of his proofs of God’s existence were based on his five basic beliefs about God. Aquinas wrote that God was: 1) simple as in having no parts, 2) perfect therefore lacking nothing, 3) infinite having no beginning and no end, 4) immutable as in never changing, and 5) one in essence and existence.

Another example states that all voluntary things can be reduced to one principle which is human reason or will. This case concludes that God’s existence is not necessary. In response to these two cases Aquinas proposes that he can prove the existence of God in five ways. These

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.

The final crucial proof of the existence of God is Aquinas fourth proof. This proof looks at qualities of humans; all humans possess many different attributes which we consider unique to each individual. This is when standards are formed humans began to have a certain criteria for how or what someone with a given attribute should act or how they should portray themselves. The only way this standard could come into existence is to believe that there is a perfect creation possessing all qualities and expressing them in the most precise and perfect way. This perfect creation is God, the person in which humans get the laws at which the obeyed by. Aquinas five proofs of the existence of God are much more extensive but just looking at the proof of motion and the proof of perfection it becomes unquestionable that there is an almighty creation. This superior creation creates laws at which

When St. Thomas wrote this section of his ground breaking essay what he ultimately was claiming, was that through philosophy and observation, there is a way to see how the natural world points to there in fact being a God. Although to some it may seem absurd, modern day science based upon observation and experimentation, does not completely discredit or debunk the first, second, third, and fifth arguments from St. Thomas Aquinas’s Five Ways, but rather it suggests substantial evidential credibility, in regards to his theories on God’s existence.Concepts, theories, and laws drawn from the

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
