For thousands of years, the nature of human intelligence has been debated, discussed and examined. Descartes’ argument that it is not bodies that think, but an immaterial substance that exists non-spatially is problematic because it vies thinking from a flawed, incomplete understanding of the human brain and its functions. Descartes would defend his claim by arguing that the thinking soul connects to the body through the brain, and while influenced by the states of the brain, exists outside of our bodies, however that would still be ignoring years of study and scientific evidence exploring the brain. The argument that the soul is what thinks, and would therefore makes artificial intelligence impossible is highly flawed.

One primary concern is our perceptions of physical objects, which according to Descartes, exist in the immaterial. He reasons that all knowledge or experience of the world exists first in the mind, and that all physical experiences prove the mind’s existence. While an experience may have been false, such as a dream, the experience of the mind did surely exist, further proving the existence of the mind, separate of the physical world. (Descartes, 1983, p. 7) Descartes reasons that all things other than one’s own mind can be doubted, even God, and that thinking is the only thing that can be known to …show more content…
These are substantial deficiencies, and leave many questions unanswered, or even acknowledged. Any defense or response to objections will ultimately revolve around Descartes’ main views, without being fully able to address concerns. Descartes’ views on intelligence revolve around an immaterial soul that connects to the body and thinks, feels, and perceives. He offers no real evidence for this view, aside from his own logic, and often uses the existence of God to fill in holes in his logic. I reject the argument that immaterial souls are responsible for thought. Even if I were to accept that as being true, I would reject the implication that an artificial intelligence could not think because of a lack of a
Descartes' error, Antonio Damasio tells us, was his belief in "the abyssal separation between body and mind . . . " (250). As Damasio notes, there are certainly many specific "errors" in Descartes' writings--that heat causes the circulation of the blood, for example, or that movement is translated instantaneously through the plenum from one object to another--but all these notions have been "corrected" by subsequent theory in ways that we can imagine Descartes himself might easily accept. The "abyssal separation" persists as the central cliché of modern philosophy because we do not yet agree on a solution, and Descartes serves as the convenient scapegoat for those who want to argue for the reduction of mind to matter. Damasio himself is part of a new generation of neuroscientists who, using the framework of connectionism or neural network theory, think they posses a solution to the mind/body [End Page 943] problem. The actual object of his attack is thus not so much Descartes but those cognitive psychologists who have defined themselves in terms of a Cartesian "nativism" or doctrine of innate elements of knowledge not derived from sensation. None of these "nativists" literally believes in mind/ body dualism, but insofar as they cling to the central functionalist dogma that mind can be instantiated in any physical system they de facto treat mind as something that can be considered apart from embodiment, and they embrace, more or less, an overtly Cartesian methodology, which Jerry Fodor has called "methodological solipsism." 1
Descartes gives reasons to say his mind could exist without his body, however these reasons are not good enough for us to agree with him. Descartes’ two strongest reasons for this are the doubt argument and the divisibility argument.
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
It is in Meditation II that Descartes relates his certainty regarding his existence. He claims that he exists because he is able to think; “I think, therefore I am.” Even though he believes that all of his senses are subject to analysis, he knows for certain that he is thinking. This leads into the concept of separation between mind and body. Meditation II is Descartes assertion that both mind and body are separate from one another. Further on in Meditation VI, Descartes evaluates the existence of material objects, away from the existence of self and the existence of God. He acknowledges that he believes that material objects can exist since they are “objects of pure mathematics.” He acknowledges that God is capable of creating everything for which he is capable of perceiving. Additionally, Descartes acknowledges that the imagination produces evidence to support the perceived existence of external
If Descartes firstly has the premise of the existence of think, maybe it would be more complete. We know, according to Descartes’s statement, the thought is inseparable from us, is a part of us. So when we think, and thinking do exist, we can prove the existence of ourselves. So the following argument maybe better for me:
Right in the beginning Descartes makes a very clear distinction between imagination intellectual thought. He states that intellectual thought is abstract and without shape, Descartes would call it e...
Descartian dualism is one of the most long lasting legacies of Rene Descartes’ philosophy. He argues that the mind and body operate as separate entities able to exist without one another. That is, the mind is a thinking, non-extended entity and the body is non-thinking and extended. His belief elicited a debate over the nature of the mind and body that has spanned centuries, a debate that is still vociferously argued today. In this essay, I will try and tackle Descartes claim and come to some conclusion as to whether Descartes is correct to say that the mind and body are distinct.
One of the ways in which Descartes attempts to prove that the mind is distinct from the body is through his claim that the mind occupies no physical space and is an entity with which people think, while the body is a physical entity and cannot serve as a mechanism for thought. [1]
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.
Once Descartes recognizes the indubitable truth that he exists, he then attempts to further his knowledge by discovering the type of thing that he is. Trying to understand what he is, Descartes recalls Aristotle's definition of a human as a rational animal. This is unsatisfactory since this requires investigation into the notions of "rational" and "animal". Continuing his quest for identity, he recalls a more general view he previously had of his identity, which is that he is composed of both body and soul. According to classical philosophers such as Plato and Aristotle, the key attributes of the soul involve eating, movement, and sensation. He can't claim to h...
In efforts to find truth, Descartes used only his logic to identify his existence. He also proved that there is some type of knowledge that we are born with. “Some of our ideas seem to be “born with me,” some “invented” by me, whereas others “come from without” (Descartes, 2008, p. 211). Which means Descartes believed that we enter this world with some innate ideas that overtime helps us to develop understanding of our sense (invented by me) and through our experiences (comes from without). Descartes was a dualist; he stated that there existed something outside of our bodies. Descartes suggested that at the “ghost in the machine” theory developed by Gilbert Ryle, which states that there is some mystical being, which we understand is the mind, that is primary to the machine (or the body). Which leads me to believe, innate ideas are active within our minds.
In Rene Descartes Discourse on Method he discusses the nature of animals. Descartes acknowledges the fact that animals are very similar to human beings, as humans and animals have the same basic design and same organs. Descartes realizes that human and animals have similar bodies but claims that animals are nothing more than bodies. He claims that animals are purely just mechanical. He argues the functions of the body are machine like as the heart, lungs, and muscles are seen to be parts of the machine. Descartes differs human beings from animals by saying that humans have souls while animals are no more than just bodies with no soul. He claims that animals are nothing more than pure machines, and believes that they have no emotions or desires. “But rather that they no intelligence at all, and that it is nature that acts in them, according to the disposition of their organs, just as we see that a clock composed exclusively of wheels and springs can count the hours and measure time more accurately than we can with all our carefulness.” (Descartes 33) Descartes sees the soul as something extra that God had gifted human beings as he sees animals without souls, personalities, desires emotions, and rational intelligence. He claims the God only gifted rational souls to human beings.
Unlike one of empiricism’s major tenets, Tabula Rasa, or blank slate, Descartes believed that the mind was not a blank slate, but actually came pre-loaded, if you will, with ideas, which are part of our rational nature and that our rational nature allows us to grasp . Descartes begins his journey deep within his own mind by claiming that all truths can be conceived by thinking about them. He calls his method cogito or pure reasoning. His famous words “I think, therefore I am,” describes the way that he thinks the mind is the true reality with the rest of reality being an extension. His example to prove thi...
Descartes was incorrect and made mistakes in his philosophical analysis concerning understanding the Soul and the foundation of knowledge. Yes, he coined the famous phrase, “I think therefore I am,” but the rest of his philosophical conclusions fail to be as solid (Meditation 4; 32). Descartes knew that if he has a mind and is thinking thoughts then he must be something that has the ability to think. While he did prove that he is a thinking thing that thinks (Meditation 3; 28), he was unable to formulate correct and true philosophical arguments and claims. For instance, his argument for faith that a non-deceiving God exists and allows us to clearly reason and perceive was a circular argument. Another issue with Descartes' philosophy is that he wanted to reconcile scientific and religious views, which is wrong since the two maintain completely different foundational beliefs and they should exist exclusively- without relation to the other. Thirdly, he believed that the mind was the Self and the Soul, failing to recognize that humans have bodies and the outside world exists, and through which we gain our knowledgeable. Lastly, Descartes argues that ideas are all innate while they actually are not- we gain knowledge through experience.
...ning of mind is something that cannot be divisible but that is hard to see because I have already proved that by my understanding of the mind it has parts. It is also hard to think of a mind or soul that does not have such things as memory and personality therefore I believe Descartes argument is false.
