In order to understand Descartes’ argument, understanding the concepts he uses is very important. There are two key principles that his argument is based on; levels of reality and the idea that causes must be at least as real as their effects. The distinction between formal and objective reality should be laid out from the beginning in order to grasp Descartes’ argument. When talking about the forms of reality, Descartes is differentiating between two ways of existing; mostly being independent or dependent to exist. Formal reality reflects the degree of independence in something’s existence. In other words, the more formal reality something has, the fewer things it needs to exist. Formal reality can be applied to everything, in different degrees, however. As for objective reality, it can only be applied to ideas as it basically is a representation of something; an object of thought. With this being said, an objective reality of an idea is equal to the formal reality of the thing that the idea is about.

First, ideas originate from causes; the latter must have as much or more formal reality as the objective reality of the idea. Second, Descartes has an idea about God, this idea has infinite objective reality because this idea, no matter what caused it has to have infinite formal reality; “because something can’t come from nothing, or the cause must have as much or more reality than the effect” (Descartes 31). Third, Descartes is finite and does not have infinite formal reality, therefore he cannot cause the idea of God because he, as a cause, would have less formal reality than the objective reality of what he produced, effect, which is the idea of God. Thus, God could have caused the idea of God in him, because only God has as much formal reality as the objective reality of his idea (Descartes 31), therefore, God
Humans are finite substances so they cannot come up with the ideas of infinite substances unless it were given to them by an infinite substance. Descartes continues that while we advance gradually each day these attributes could never exist within us because we are only potentially perfect whereas God is actually perfect. Furthermore, Descartes argues that only God could be the author of his being because if it were he or his parent’s other finite substances that authored his being then he would not have wants or doubts because he would have bestowed upon himself every perfection imaginable to a finite being. Therefore, God exists because Descartes could not have thought of God because he is a finite substance thus the idea of God must have come from an infinite substance.
I have an idea of a perfect being; it must contain in reality all the
From Descartes point of view, he thinks that it makes sense to talk of degrees of reality to qualify the above assumptions, and he sometimes equates this with talk of degrees of perfection. Thus, he brings God back into the picture. The ideas, then, could come from only God, or from another being superior to humans but inferior to God. But this, too, is impossible, argues Descartes, as if it were the case that God produces the ideas of bodies in humans, then the very strong inclination we have towards believing that the idea-producing bodies resemble the ideas we have would be false and thus God would be allowing us to be deceived which is not permissible. The same would apply if any other being were producing
Descartes’ skeptical arguments begin from the thought that everything can be doubted; the first being our senses. He claims that our senses can sometimes deceive us (e.g. when viewing things from far away). Things that can deceive us once, have the possibility to be deceiving us all the time—giving us reason to doubt all sensory claims. This leads to a problem since humans rely on empirical knowledge. If one cannot consider any claim delivered by sense to be true knowledge, then it gives reason for one to doubt reality. Following is the dream argument in which what seems to be tangible reality, is an effect of a dreaming experience. Descartes gives the example of dreaming he is sitting by a fire when in actuality he could be asleep
Descartes is able to examine ideas and gain knowledge form them. Innate ideas mean they are present at birth, in other words we are implanted with certain ideas at our creation. He often uses ‘innate ideas’ to explain the mind’s original programming. “An infant’s mind is programmed with the rules of logic. Consider as an example the valid rule, modus ponens. Let P and Q stand for variables… the rules states that, if P then Q is true and P is true, then it follows that Q is true. We know that we are programmed with this rule because young children, who have never studied logic and have never entertained the rule, when given an argument in which the variables above are replaced by actual sentences, are able to intuit the validity of the argument.” Descartes believed our minds are programmed with eternal truths, “Whatever comes into existence must have been brought into existence by something else.” He also discovers that the idea of God is only part of his initial programming but also that God, operating through secondary sources such as his parents, is the programmer.
Descartes’ Dreaming Argument comes from his thinking that there is no way of knowing if you are sleeping or if you are awake. To know something is to have no doubt of a fact, it must be a justified true belief. To be justified it must hold logical reason, you cannot state something is true without evidence. In order for it to be true it is not enough to justify it, but it must be justified with true facts. Finally, you must believe it, in order to know something it must be true in your mind. As a result Descartes doubts his consciousness as he cannot truly know that he is awake. This spurs Descartes to question if any perceived knowledge of reality is really true. Descartes calls his senses into questions as he notes, “it is prudent never to trust completely those who have deceived us even once” and therefore concludes that as a result it is prudent, never to trust his sense. In
In my conviction, sense experience cannot always lead us into certainty. Descartes uses doubt as a method to search for certainty. His primary concern is knowledge which searches for certainty and the grounds for certainty are its driving force. He prefers mathematics to use as a model for it is the ideal of all knowledge due to its clarity and certainty. Diogenes Allen persuasively discusses that Descartes` method of reaching at certainty is to commence with by doubting everything which can be doubted untill he arrives at undoubted even by making the most unconvincing and improbable assumptions intending to liberate us from reliance on sense perception as well as other prejudices so that the mind can work unhindered. This implies that we
As the first “premise” of his proof Descartes makes a very important distinction between the various types of ideas. The first type of idea he discusses is ideas that are images of things. This type of idea, when thought of, is apprehended as an object of my thought, but there is something more embraced in the thought than merely the representation of the object. Now if these ideas are considered only in themselves, and are not referred to any object beyond them, they cannot, properly speaking, be false. This even applies to the will and affections, a second type of idea, for although I may desire objects that are wrong, it is still true that I desire them. The third type of idea is that of judgement. Descartes goal in this classification is to find in his mind which of the ideas are the proper bearers of truth and falsehood. Considered in themselves, ideas are not false nor are desires. The only place where mistakes can be made is in making judgements. As Descartes says, “And the chief and most common mistake which is to be found here consists in my judging that the ideas which are in me resemble, or conform to, things located outside me.” Descartes further classifies his ideas by their origin: those that appear
Descartes utilizes another rule in his thought process which states that objective reality cannot exist without formal reality. By this he means that we cannot form an idea without a cause. Assuming that God does exist would be an example of a Formal reality. Whereas the idea of God, is considered objective reality because it represents an infinite substance. Ideas themselves automatically have objective reality because the idea itself represents some reality. Also, the more perfect ideas cannot come from the less perfect; this is called The Causal
After giving his first proof for the existence of God Descartes concludes by mentioning that this proof is not always self-evident. When he is absorbed in the world of sensory illusions it is not quite obvious to him that God’s existence can be derived from the idea of God. So to further cement God’s existence Descartes begins his second proof by posing the question of whether he could exist (a thinking thing that possesses the idea of an infinite and perfect god) if God itself did not exist.
Descartes’s attempt to prove the existence of God begins with the argument that he has the clear and distinct idea of God as the “most perfect being and that there must be at least as much reality in the efficient and total cause in the effect of that cause” (40). Therefore, this idea of God can’t be from himself, but its cause must be God. So God exists. In what follows I’ll explain these terms and why the premises seemed true to him.
In the Third Meditation, Descartes forms a proof for the existence of God. He begins by laying down a foundation for what he claims to know and then offers an explanation for why he previously accepted various ideas but is no longer certain of them. Before he arrives at the concept of God, Descartes categorizes ideas and the possible sources that they originate from. He then distinguishes between the varying degrees of reality that an idea can possess, as well as the cause of an idea. Descartes proceeds to investigate the idea of an infinite being, or God, and how he came to acquire such an idea with more objective reality than he himself has. By ruling out the possibility of this idea being invented or adventitious, Descartes concludes
The second argument that Descartes defends is another question posed towards the senses. How can we take anything as real if our dreams cannot be
Descartes reasoning shows that as part of his a posteriori claim, God’s existence depends on our idea of God as a perfect being. However, he writes that “From this I knew I was a substance whose whole essence or nature is solely to think, and which does not require any place, or depend on any material thing, in order to exist” (Descartes, Discourse on the Method, page 36). As per Descartes, the existence of his mind is partially based on the notion that it’s (his minds) existence is independent of any other being. His causal proof of God, however, depends entirely on the human mind and its ideas of what God is. Aside from these flaws in his reasoning, Descartes also mistakenly links his proofs together, attempting to propagate them and champion their creditability.
Given the above arguments one can begin to understand the nature of the God Descartes is endeavoring to prove. For Descartes, God is infinite and perfect existence. God is “eternal, immutable, independent, supremely intelligent, supremely powerful, and [the creator of] everything else". (Descartes 20) Not only does God possess this nature but it is necessary that He does so. If God is not infinite or perfect God could not exist as these attributes are essential to God's existence. Furthermore, if God is not the ultimate creator the innate idea of God we experience would cease to be innate but adventitious (externally caused) or imaginative (caused by the mind) which is again impossible given its content. Given these qualities one can draw a connection to the
