S. Thomas Aquinas provides five arguments for the existence of God; which are cosmological arguments, meaning they begin with how the world existed and the existence of God. The arguments are intended to influence individuals to believe in the existence of God. The argument we will focus on is the second argument, known as a causal argument for the existence of God. The second argument provided by St. Thomas Aquinas derives from the “nature of the efficient cause” (Aquinas: 42). This means that the things that happen all have causes, something else caused that thing to happen; there is a cause therefore an effect. For example, when people pray, there was a cause for them to pray: they are grateful for something, something is wrong, they need help with something, or they just simply want to help, or even because it makes them feel better. So the effect is what happens after you pray. Basically, this second argument attempts to tell individuals that if it were not for the existence of God in the first place, of the world, everything would not have existed at all. God was the first cause of everything.St. Aquinas's second argument also tells us that we live in a world where things happen in order, something causes other things to happen for a reason, there is an order of causes in the world. Things happen in order because it has to be that way, if it didn't happen in order, things couldn't happen in the first place. He also gives us another reason why everything has a cause, he states: “There is no known case (nor is it, for that matter, possible) in which something happens to be an efficient cause of itself; for thus it would be prior to itself, which is impossible” (Aquinas: 4...... middle of paper ......and God in the first place to exist, there is no casual reason. St. Thomas Aquinas provides arguments that work, but does not yet prove that God exists. Furthermore, in a chain of existence, at some point a cause has partly caused itself, since he says that God is the first cause but does not provide an explanation. to why God is the first cause, or how he knows that God is the first cause. There is always an explanation to causes. If there were no first cause, there would be no final or intermediate cause. is no explanation of why those things are. This second argument demonstrates good arguments about causes, but it doesn't actually explain the existence of God. There should be a further explanation of why nothing caused God to exist, why he is. uncaused and being the first cause of everything, which is why it is not yet clear whether God exists.
