Question: Explain how Thomas Aquinas tries to prove Gods Existence (30)

St. Thomas Aquinas (1225-1274) was a Catholic Italian Monk who was regarded to be one of the most important philosophers of the medieval period. Aquinas had adopted the works of Aristotle's analysis of physical objects, his view of place, time and motion, his proof of the prime mover and his cosmology. He tried to connect the Christian faith together with the Philosophy of Aristotle’s work in his 'Summa Theologica'. Aquinas used 5 arguments to do this, with the first 3 being regarded as the Cosmological Argument, as the arguments were coherent and summed up to the same conclusion that; there must be a cause of the cosmos, and that cause being God. His main achievement was to bring together faith and reason and Aquinas had used the theory of A Posteriori in order to address this. This term basically just means that things have not been learnt/accepted on the base of experience, and Aquinas used this to claim that we have no direct understanding of God's nature as perfection, as the starting point to his argument.
Aquinas's first way to prove Gods existence was known as the argument from Motion. As Aquinas had stated in his Summa Theologica, on the third Article 'Whether God exists' ''It is certain and evident to our senses, that in the world some things are in motion''. Through our senses, such as feeling, observing, tasting, we are able to perceive that a real world exists, and this is how Aquinas would prove that a real cosmos also would exist. Nothing can theoretically move by itself, every object in motion would have a mover, and this mover would also have a mover. However you cannot have an infinite chain of movers? Therefore Aquinas thought that there was an unmoved mover and this was known as 'God'. Something must have put the object moving into its state and it maybe could have been an external supernatural power. As Philosopher Peter Kreeft mentioned that if

    In his Summa Theologica number seventeen, article two, Aquinas is trying to answer the question of whether there is falsity in the senses and, if there is, how it exists. He concludes that falsity does exist in the senses in the way that the senses can misjudge objects. Aquinas maintains that the senses can perceive the likeness of an object in one of three ways. The first is by the color of the object and other proper qualities which occur in only one sense. The second is by the common qualities of shape and size which can be validated by more than one of the senses. Finally, the third occurs accidently and not of its own nature. He follows that by stating the premises for his argument. Aquinas’s first premise is the sense gains false knowledge…

    The idea of God is intense, as both of these analyses have shown. Aquinas’ idea of God is “Ipsum esse subsistens,” or Subsistent Act of Existing Itself (Magee, 2015). To speak of God as a self-subsistent being is to say He “Just Is.” He articulates every creature is “fundamentally composed of essence and existence.” In order for everything to exist, there must be a First Cause and Aquinas says God is that cause because without it, nothing exists. God is infinite simplicity and perfect. Aquinas and Tillich both see God as Being Itself (Fesser, 2011). Tillich places God “above God.” He writes, “God does not exist.” However, this is not in an attempt to deny God, but to demonstrate that God transcends everything.…

    Thomas Aquinas proposes a number of laws that exist in the world. He believes that God is responsible for eternal law. Aquinas points out that eternal law the way the universe is structured. He understands that a rational being must exist, who is responsible for the structure of the universe, and that rational being must be God. This category of law applies to all things in the universe ranging from rocks to human beings. All of these things have natural tendencies that…

    Aquinas proposed the way of motion through the idea that in the world some things are in motion and whatever is moved is moved by another. He argued that it is impossible for something to be both mover and moved. Motion is therefore a change of state and is not just movement in time and space from one place to another.…

I shall outline Aquinas’ understanding of voluntary ignorance and involuntary ignorance as an excuse from blame.

    Thomas Aquinas is a medieval scholar who wrote the five cosmological arguments that support the existence of God. A cosmological argument is an argument that supports the existence of God and that everything that exists was caused by something else. One of Aquinas’ ways to prove God’s existence is through the argument of possibility and necessity. He argues that there must be a first necessary being to set the chain of causes in motion which results in the universe today.…

    Thomas Aquinas. Again, he believed in God but disagreed with Anselm’s argument proving his existence. Aquinas raises questions about God’s self-evident existence. He claims that things can be self-evident in two ways: in itself and both in itself and to us; even though something may exist self-evidently in itself, this self-evidence may not be known to us as humans and therefore, its existence would not be self-evident to us. This is exactly what Aquinas proposes God to be. God is self-evident in himself because he is his own essence. However, seeing as this essence is unknown to us (as we do not know enough about him), the statement ‘God exists’ is not self-evident to us. This, again, is another criticism which holds weight against the Ontological Argument, highlighting a glaring weakness in its…

    St. Thomas Aquinas presents one of the earliest teleological arguments in his Summa Theologica. Aquinas argues that anything with knowledge moves toward and end or cause. But, natural bodies, or planets, do not have knowledge and they still move toward an end. By an end, Aquinas means that the planets take the same path of orbit around the sun. Thus, Aquinas argues, if an unintelligent body is moving toward an end, it must be directed by an intelligent being. This intelligent being must be God (Aquinas, Summa Theologica, Article 3, Question…

    This particular argument is also in favor if the idea that God does in fact exist, but Aquinas has a different explanation from Anselm. Thomas Aquinas presents the argument known as the “Cosmological” or “first cause”. In a few words, this means that Aquinas believes there must have been a first cause in the world. Aquinas argues that the proof of Gods existence is based on the basis of experiences. God must exist because every being that is dependent for existence was caused by something else that happened prior to it. He believes either there is a boundless chain of contingent beings that is extending backwards or there is a first cause, something that was not caused by something else but began everything else. But in reality, there cannot be a continuous chain extending backwards. Therefore; there is a first cause, something that was not caused by anything else but started everything else that currently exists. Aquinas claims the existence of God can be proven in five ways: Argument from motion, Nature of efficient cause, possibility and necessity, gradation, and Governance of the world. Aquinas gives us an argument that is not hard to interpret. There must have been one who created mankind, constructing the world one being at a time. It is very easy to go along with the idea that there is one person or thing that created everything else. While this argument is clear and…

    Agnosticism - 1

    • 1113 Words

    Thomas Aquinas is a firm believer of the existence of a god; He argues for the proof of god by his five proofs. For motion to take place, something must have caused it to move, every effect has a cause, Something that doesn’t exist cannot make something come into existence, a standard of living, and all beings considered unintelligent half to be led some something. For his first “proof of God” Aquinas argues that any motion that takes place requires something to cause it to move. For example a ball won’t move, unless a slope causes it to roll down a hill, or a child kicks it. So the ball always had the potential to move, but its potential cannot be reached unless something acts upon it. By this theory something had to start the movement of the universe, which the only first mover could be God. In his second proof Cause and effect is brought into play. It is very similar to his first proof in that nothing would happen unless something caused it to happen. And because an infinite series of cause and effect is irrational, there must be an original cause that requires no cause; Hence God. The third proof deals with being or not being. All things have the possibility of existing or not existing. The shirt that you are wearing now exists but there was a time when it did not. Aquinas’s argument is that for that something to go from not being to being, there had to be an original being to create it. For example the shirt that you wear had to be created in a factory; And to manufacture something you must “be”. So…
