Aquinas Second Way Analysis

718 Words 3 Pages
In the Summa Theologica, Thomas Aquinas claims that there must be a first efficient cause to existence and that therefore a chain of causes cannot infinitely continue. This is also known as Aquinas’ second way. An efficient cause is an agent that brings about a change or an effect. Aquinas uses the term to argue that a first efficient cause is needed in order for there to be existence. I will argue that there can be more than one first cause, since Aquinas never explicitly stated that there is only one first efficient cause. Thomas Aquinas’ second way argues that there must be a first efficient cause which causes other things to exist. This first cause cannot have come into existence by itself. Something must come into existence by a first …show more content…
However, Aquinas does not say that there must be only one efficient first cause, he just simply argues that there must be a first cause, in which it could not have caused itself into existence, and that a chain of causes cannot be infinite. Aquinas’ argument claims that there must be at least one efficient first cause, meaning that there could be more than one. In this situation, each first cause is responsible for a certain part of the outcome, being the effect. These multiple first causes are similar to the division of labor. Division of labor is the assignment of different tasks within a system to improve efficiency. It is like a chain of dominos, but with two starting points that lead into one trail. If both of the starting points are knocked over at the same time, the domino effect will continue at the same rate of time until they both reach the single strand that they are connecting to, thus merging and having two first causes to the dominos collapsing. Simply saying that because there is an uncaused first cause does not mean or prove that there can only be one, rather there could be …show more content…
If there is then no order, it appears to be impossible for things to come together at once to create an effect. For example, if a human were to be created, how would the multiple first causes create this effect of a human? One first cause could be in charge of the skin, another the bones, the heart, the ribs, etc. but these developments would have to have some kind of order or process in order to create the effect of a human. Hence, the first causes have no way of ordering themselves to create something as complex as a human. Even compared to the domino effect of two strands leading into one, this certainly works in terms of motion, but with a complex process of first causes leading to a single effect, it does not work. Aquinas would agree with this because the idea of having multiple first causes does not work. His argument seems to be better than this objection because having a singular first cause in charge of everything appears to work more efficiently and makes more sense than to have multiple first causes leading to one effect. Having a singular first cause would mean that it has complete control of creating the

• Analysis Of Richard Swinburne's Cosmological Argument

As Swinburne stated that there could be no simpler explanation than the one which postulates only one cause. Theism is simpler than polytheism. The Criteria that needs to be met according to him, to prove or disprove the existence of God is meant by only the personal explanation which gives us the ultimate explanation for the existence of the World. However, while this may convince many individual that Theism is indeed correct, I would disagree because our interpretations depend on how much we are prepared to trust a posteriori knowledge. “For those who believe, no proof is necessary.…

• Induction In David Hume's Argument

One very impressive attack on Hume’s argument, trying to solve it with its definition, is as follows. The first premise of the argument is challenged, which is “if we want induction to be rationally justified, induction must be reliable.” Since the definition of deduction is based on the validity of an argument, which is assumed to be reliable, why couldn’t reliability be a part of the definition of induction? Induction is defined to be reliable in this attack. However, reliability cannot be a part of the definition because it is a way to evaluate those methods, such as deduction and induction. The criteria for the evaluation is a totally different idea than the method itself.…

• Kalam Cosmological Argument Essay

Therefore, God could not have caused our universe by existing outside of temporal moment before our universe existed and have the existence of our universe. In response to this, Craig argued that the cause of the origin of the universe is causally prior to the Bang, though not temporally prior. This brings about the notion that time begins with the beginning of the universe. The cause of the universe, whatever it may be, is itself not temporal, since its existence is required in order for the universe and time to come into existence. Even if we accept the Craig's idea of causation rule, we cannot assume that this definition is applicable to our entire vast universe based on our very limited knowledge of our observable world.…

• Cosmological Argument

The first opposition he brings upon the cosmological argument is that “Nothing is demonstrable, unless the contrary applies a contradiction.” This opposing argument says that if we conceive something to exist, we also conceive that thing to not exist; and there is no bring in which its existence implies a contradiction. If this is the case, then there is no being thats existence proves to be necessary. Cleanthes also asks “Why may not the material universe be the necessarily existent Being, according to this pretended explication of necessity?” (Cleanthes, First Philosophy, pg.80.) This argument is bringing to light the question of whether or not we can assume we know God’s properties, if we in fact cannot settle on exactly what the philosopher 's God can or cannot do. There may be an attribute of God’s that makes his existence necessary that we simply are unaware of and cannot dismiss.…

• Argument: The Implications Of Avicett's Kitab Al-Najat

I agreed that the first possibility should be rejected. In that case, the rational faculty has the knowledge of the form of the organ. However, the observation made by the organ is not reflected on the form of the organ, since the form is commonly defined as the perfect state of matter. Hence, the information received by the organ cannot be conducted through the form that is acquired by the faculty. No new knowledge would be received by the rational faculty, so we cannot claim the faculty know through a organ.…

• Plato, Pao And Hume's Argument For Design

In the same way the universe demands a designer, it simply could not be the product of chance. Thus, there must be a superior being, big enough to create a supreme artefact such as the universe. Finally, David Hume likened the world to ‘one great machine subdivided into an infinite number of lesser machines’. This theory however leads to the philosophy that similar effects require a similar cause. Through the thrust of Hume’s argument, he introduces us to two characters that express the argument for design; whilst a third, namely Philo, criticises the…

• Analysis Of St. Thomas Aquinas Treatise On Happiness

If we never can know what the universal end is or how to get there, then we can never progress towards it and therefore never achieve it. It is possible to argue that since we each strive to be the best version of ourselves, this can be defined as the universal end. I find this definition as incomplete and inconsistent because it is a sweepingly broad term when in reality each person has a different “best version” in mind. Even though this argument may make sense, Aquinas would probably have some obvious objections. First, Aquinas would argue that the universal end does not need to be achieved in order to strive towards it, or it can be achieved in some way that transcends the material world.…

• Kuhn's Theory Of Incommensurability

The concept of incommensurability is presented in Kuhn 's early views as an impediment to the comparability of theories belonging to separate paradigms (Sankey 1993, p. 761). The logic behind this argument rests in the idea that incommensurability forbids translatability and that translatability between paradigms is necessary for comparability (Sankey 1993, p. 765). Logically it must follow that commensurability is necessary for comparability. To state the problem of comparability in Kuhn 's own words: "There is no algorithm of theory choice [...] which, properly applied, must lead each individual in the group to the same decision" (Sankey, 761). I refute this claim by arguing that competing theories are often incommensurable yet…

• Review Of Anselm's Argument For The Existence Of God

Both explantion go against the eternal nature of God, which is necessary to be the greatest conceivable being. Therefore, if God does not exist then his existence is impossible. But whatever is conceivable is possible therefore God must exist. Under this argument it is irrelevant if existence is an attribute or not, solving the problem with Anselm’s ontological…

• Paley's Argument Analysis

I believe that the global argument from design is not cogent because William Paley is not able to overcome the fallacy of composition, hereby creating an analogy between man-made objects and the universe although the universe does not necessarily have to be contingent upon anything else to exist. Other avenues to explore in the future could be to consider where the theory of evolution fits into the argument. Based on that theory, things may appear as though they were designed in a tactical way, but have merely adapted so that they are able to exist in the most favorable way that they can. The theory of evolution is yet another reason why the argument from design is…
