Universal Doubt of Senses
We are taught, at a young age, how important our five senses are. These senses are essential to survival and are the necessary feedback for our existence. The question becomes though, what are really our senses? Touch, smell, sight, hearing, taste are the ones engrained into us, but there’s more to it, we can sense temperature, acceleration, movement, and even intangible things such as hostility, fear, or even someone or something’s gaze. While questioning why these are important and vital senses it raises a question of what is not included in the taught set of senses. Are senses real or are they a figment of our imagination created to give us a virtual reality? When people have senses that are better than others does that make our senses reliable? Rene Descartes ran into these questions himself in his Meditations on First. He distorted the perspective of senses by relabeling the concept of dreams, the beliefs of a powerful entity, and the mind itself. Descartes decides to call all individual opinions into doubt,

We think that God is good and has created the universe. Being an omnipotent individual “nothing can be added to his [God] perfection” (Descartes, 32). Our divine being also has given us the ability to determine reliable sources, whether its food or friends. If God were to be deceptive in nature then why would he allow us to freely think in a way that would figure out the deceit? Another argument is that God would not let us know what deception is in the first place since it would imply imperfection and contradict the nature of God; “the ability to deceive seems to be an indication of cleverness or power, the will to deceive undoubtedly attests to maliciousness…deception is incompatible with God” (Descartes, 36). It would not be a concept familiar to us so we could never know of its existence. So this would clearly rule out Gods play in the fallacy of
Sense Perception is a way of knowing in which a person can acquire knowledge using their five senses - taste, touch, sight, sound and smell. Sense perception is an important in our understanding of the world, and is a source of much of the pleasure in our lives. But, can we trust our senses to give us the truth? This may come out as an odd question to many because according to experience and history it is known that humans greatly rely on sense perception as a means of survival. However, like all ways of knowing, sense perception has its weakness; our senses can easily be deceived. In his TED Talk, “Are we in control of our decisions?” behavioral economist Dan Ariely uses examples and optical illusions to demonstrate the roles, strengths and limitations of sense perception as a way of knowing.
One cannot deny the senses however the mind is what allows the senses to even be perceived. Descartes broke his argument down so that it can be followed easily. This method virtually diminishes any counterarguments because he is basing it all on examples that are easy to grasp and relate to. His conclusion was based on solid fact building stating with the basics of the senses and guiding to his deeper understanding of what all the mind is and how it is distinct from the body through the body’s physical
God is not a deceiver to me; God is good, so therefore what I perceive really does exist. God without existence is like a mountain without a valley. A valley does not exist if there is no mountain, and vice versa a mountain is not a mountain without a valley. We cannot believe or think of God without existence. We know the idea of God, and that idea inevitably contains his existence.
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 addition, to the third Meditation, Descartes further explains God’s existence as a non – deceiving entity of natural light in Meditation IV. Descartes stands with his position that God is perfection by saying “it is impossible that God should deceive me”. For in every case of trickery or deception some imperfection is found.
At the beginning of the very first meditation, Descartes states that he has lost his trust with his senses because they can be easily deceived (Descartes, 18). While dreaming sometimes it feels very real just as it does whi...
Second, Descartes raised a more systematic method for doubting the legitimacy of all sensory perception. Since my most vivid dreams are internally indistinguishible from waking experience, he argued, it is possible that everything I now "perceive" to be part of the physical world outside me is in fact nothing more than a fanciful fabrication of my own imagination. On this supposition, it is possible to doubt that any physical thing really exists, that there is an external world at all. (Med. I)
He quickly releases that this is the foundation of most of his beliefs. He first acknowledges that sometime our senses can deceive us, but say that our senses is mostly sturdy. It is after this that Descartes realizes that there has been times where he has been sleeping and in his dream he was certain that he was awake and sensing real objects. Though his current senses may have be dream senses, he suggests that even dream senses are drawn from our experience of us awake. He then discovers that there are times in which he cannot distinguish whether he is in his waking state and his dream state.
The teaching of Descartes has influenced many minds since his writings. Descartes' belief that clear and distinct perceptions come from the intellect and not the senses was critical to his ultimate goal in Meditations on First Philosophy, for now he has successfully created a foundation of true and certain facts on which to base a sold, scientific belief structure. He has proven himself to exist in some form, to think and therefore feel, and explains how he knows objects or concepts to be real.
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
Outline and assess Descartes' arguments for the conclusion that mind and body are distinct substances.
Descartes first meditation included a few arguments that Descartes studied and analyze. The one I choose to analyze was his argument of sense deception. The actually argument is the following: (1) My senses sometimes deceive me. (2) If my senses sometimes deceive me, then they might always deceive me. (3) If my senses might always deceive me, then I cannot be certain about any beliefs acquired through my senses. (4) If I cannot be certain about any beliefs acquired through my senses, then I must suspend judgment on those beliefs. (5) Therefore I must suspend my judgment of those beliefs. To put this is premise conclusion argument form, it would look like this:
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.
Descartes makes a careful examination of what is involved in the recognition of a specific physical object, like a piece of wax. By first describing the wax in a manner such that “everything is present in the wax that appears needed to enable a body to be known as distinctly as possible” (67), he shows how easily our senses help to conceive our perception of the body. But even if such attributes are modified or removed, we still recognize the changed form, as the same piece of wax. This validates Descartes’ claim that “wax itself never really is the sweetness of the honey, nor the fragrance of the flowers, nor the whiteness, nor the shape, nor the sound” (67), and the only certain knowledge we gain of the wax is that “it is something extended, flexible, and mutable” (67). This conclusion forces us to realize that it is difficult to understand the true nature of the wax, and its identity is indistinguishable from other things that have the same qualities as the wax. After confirming the nature of a human mind is “a thinking thing” (65), Descartes continues that the nature of human mind is better known than the nature of the body.
It is easy for us to believe that what we experience with our senses is true, including in our dreams, but according to Descartes, we should look beyond our senses and use reasoning to determine what is certain. Descartes’ question, “For how do we now that the thoughts that arise in us while we are dreaming are more false than others, since they are often no less vivid and explicit?” (34), is asked so that we will acknowledge that our senses can easily mislead us. This should then cause us to use reasoning to differentiate between truth and illusion, and both authors agree that reasoning should be the guide to true knowledge. Though he believes in the attainability of certain knowledge through using reasoning, Descartes argues that there are only a few things about which we can be certain. Descartes’s philosophy “Cogito, Ergo Sum,” which means I think, therefore I am proves this. He believes that because our mind acknowledges that we can think and have doubts, we can be sure of our existence; if we stopped th...
In his Meditations on First Philosophy, Descartes states “I have a clear and distinct idea of myself, in as far as I am only a thinking and unextended thing, and as, on the other hand, I possess a distinct idea of body, in as far as it is only an extended and unthinking thing”. [1] The concept that the mind is an intangible, thinking entity while the body is a tangible entity not capable of thought is known as Cartesian Dualism. The purpose of this essay is to examine how Descartes tries to prove that the mind or soul is, in its essential nature, entirely distinct from the
