Recommended: Objections to descartes doubt

There are few faults in Descartes’ views, but few nonetheless. For one, Descartes reasoning for his cogito argument is flawed. Descartes proposes the idea of defective nature doubt and that instead of being created by god he was created by an evil genius, an evil genius that has created him as a deceived person and therefore his judgement and perception of reality is that of a defective nature. Descartes admits that he is not able to correctly perceive reality and therefore dismissing his own use of logic, but immediately after that explanation of his doubt Descartes uses his logic to produce an argument for his existence. How can Descartes be sure that he is not being deceived by his defective nature when coming to this conclusion? He cannot.

    In Meditations, Descartes brings doubt to everything he believes because it is human nature to believe that which is false. He states that most of what he believes comes from the senses and that a lot of times those senses can be deceived. His conclusion of doubting everything is based on his example of a basket of apples. It goes as follows; you have a basket of apples but you fear that some apples have gone bad and you don't want them to rot the others, so you throw all the apples out of the basket. Now that the basket is empty you examine each apple carefully and return the good apples to the basket. This is what he does with his beliefs, he follows and keeps only those beliefs of which he is sure of. Our beliefs as a whole must be discarded and then each individual belief must be looked at carefully before we can accept it. We must only accept those beliefs we feel are good.

  • Mediations of First Philosophy by Descartes

    1291 Words  | 3 Pages

    In earlier meditations Descartes proved that he existed through the Cogito argument. Descartes must now move on to examine and explore questions about the world around him, but instead of doing this he first stop to examine the question of whether or not God exists. Descartes wants to know that he was created by an all knowing, perfect creator that is good and wants to make sure that he was not created by an evil spirit or demon. If Descartes can prove that he was created by a perfect all knowing creator then his ideas must carry some semblance of truth, because God is not a deceiver and he must of placed these ideas in Descartes. Descartes has good reasons for searching for the answer to the question of God’s existence, now he has to come up with a good sound argument to prove it.

    My thoughts on God are clear and distinct that he is existent. Descartes’ now has ‘rebuilt’ the world, solely because of his power and reasoning. Descartes’ is only able to use his power and reasoning because he knows God is a guarantor of his ideas and thoughts. As Descartes thinks about his own imperfections, it leads him to think about perfection, and how it has to come from something superior to him.... ...

  • The Cartesian Circle is Wrong

    1602 Words  | 4 Pages

    ...ircle may have had a solid foundation and belief. However, I just gave you, with supporting evidence, my view of why the Cartesian circle is wrong and why I believe that Descartes was trying to make the point that God must exist in order for him or us to even have the clear and distinct perception to dwell on the idea of God, an idea that only God himself created. I hope this solves the issue of the Cartesian circle and hopefully strengthens Descartes argument of how the circle is false and he was maybe just misunderstood. My claim will stand that the Cartesian circle was just a big misunderstanding, and Descartes, by no means, interacted with the belief and structure of this falsified circle.

  • Brain Gives Birth to Reality

    Descartes assured his existence through the conviction of "Cogito, ergo sum" which translates into “I think therefore I am” (Popkin & Stroll 198). In order to question ones existence one must exist, non-existence cannot question itself. I know that my mind exists because I am here to question its existence. To concretize this idea, imagine a house and you are building a house on ground which you see. The house is built out of wood, metal, and earth on the ground. Does the house exist because of the materials used to build it or because your mind tells you that it exists? Well based on Descartes, there are no such things as wood or metal in reality because the only thing that is real is the mind itself and the built house is a figment of your mind to what you perceive as real better known as an illusion. Therefore all that we sense is an illusion and everything outside the mind is uncertain of existence. Furthermore this leads to the ...

    He argues that if he does not solve God’s existence, he will not be certain about anything else. Thus, Descartes says that he has an idea of God and, therefore, God exists. However, in order to be certain of His existence, Descartes provides proofs that will illustrate his reasoning. The four proofs include formal reality vs. objective reality, something can’t arise from nothing, Descartes cannot be the cause of himself, and therefore, the bigger cause is God. Now that Descartes knows God is real, he must solve another aspect, which is if God can be a deceiver. Descartes believes “it is clear enough from this that he cannot be a deceiver, since it is manifest by the natural light that all fraud and deception depend on some defect” (89). In other words, God possesses all of the perfections that Descartes cannot have but those perfections that are in his thoughts, concluding that God has no defects whatsoever according to the natural

    Descartes succeeded in some parts of his proof for the existence of God, but failed in proving God’s existence from a logical point of view. Most religions prove that anybody can be right in his own description of existence of God. So, Descartes is right in his own way, but to others to accept his idea is totally up to them. No one is certain that God exists. Although there are many causes that could make one believe God is for certain, those causes which might be perceived, does not necessarily make them true.

  • Serious Errors within Rene Descartes’ Meditations on First Philosophy

    1094 Words  | 3 Pages

    In the first meditation, Descartes makes a conscious decision to search for “in each of them [his opinions] at least some reason for doubt”(12). Descartes rejects anything and everything that can be doubted and quests for something that is undeniably certain. The foundation of his doubt is that his opinions are largely established by his senses, yet “from time to time I [Descartes] have found that the senses deceive, and it is prudent never to trust completely those who have deceived us even once”(12). First, Descartes establishes that error is possible, employing the example of the straight stick that appears bent when partially submerged in water, as mentioned in the Sixth Replies (64-65). Secondly, he proves that at any given time he could be deceived, such is the case with realistic dreams. Further, Descartes is able to doubt absolutely everything since it cannot be ruled out that “some malicious demon … has employed all his energies in order to deceive me” (15). The malicious demon not only causes Descartes to doubt God, but also sends him “unexpectedly into a deep whirlpool which tumbles me around so that I can neither stand on the bottom or swim on the top”(16). Descartes has reached the point where he must begin to rebuild by searching for certainty.

    Descartes argument for his existence came from the doubt he had about everything around him. This doubt was generated by the idea of an evil genius. Descartes invented the evil genius to be an all-powerful and all-deceitful being. By creating the possibility of an evil genius, Descartes found the doubt he needed in order to be able to doubt everything he once believed. The evil genius was able to deceive ...

    According to Descartes, “because our senses sometimes deceive us, I wanted to suppose that nothing was exactly as they led us to imagine (Descartes 18).” In order to extinguish his uncertainty and find incontrovertible truth, he chooses to “raze everything to the ground and begin again from the original foundations (Descartes 59).” This foundation, which Descartes is certain to be the absolute truth, is “I think, therefore I am (Descartes 18).” Descartes argues that truth and proof of reality lies in the human mind, rather than the senses. In other words, he claims that the existence of material objects are not based on the senses because of human imperfection. In fact, he argues that humans, similarly to Plato’s Allegory of the Cave, are incapable of sensing the true essence or existence of material objects. However, what makes an object real is human thought and the idea of that object, thus paving the way for Descartes’ proof of God’s existence. Because the senses are easily deceived and because Descartes understands that the senses can be deceived, Descartes is aware of his own imperfection. He

  • Third Meditation, by Rene Descartes

    869 Words  | 2 Pages

    Descartes affirms that he is certain that he is a thinking thing. His reasoning, however, seems to be a circular argument. Descartes knows he is a thinking thing because “in this first instance of knowledge, there is nothing but a certain clear and distinct perception of what I affirm” (Descartes, 24). He concludes, “everything I very clearly and distinctly perceive is true” (Descartes, 24). Descartes could only know that what he clearly and distinctly perceives is true if he can be certain he is a thinking thing. Throughout this proof, Descartes is trying to use God’s existence as a way of affirming that which he clearly and distinctly perceives. However, he is also trying to prove God’s existence by claiming that the idea of God is a clear and distinct perception. Without inquiring into the existence of God, “it appears I am never capable of being completely ...

  • Descartes Skepticism

    1205 Words  | 3 Pages

    Descartes’ first two Meditations are arguably the most widely known philosophical works. Because of this, one can make the error of assuming that Descartes’ method of doubt is self-evident and that its philosophical implications are relatively minor. However, to assume this would be a grave mistake. In this paper, I hope to spread light on exactly what Descartes’ method of doubt is, and how, though it furnishes challenges for the acceptance of the reality of the external world, it nonetheless does not lead to external world skepticism.

    Firstly, Descartes made the mistake of supporting a conclusion with premises that can only be true if the conclusion was a premise for the other premises that were supporting it. To clarify, Descartes basically stated that the clarity of his reasoning and perceptions are only possible through the existence of a non-deceiving God and that the non-deceiving God can only be proved through the clear reasoning and perceptions that the non-deceiving God bestowed upon him (51, 52). This is clearly a...
