Dualism claims that reality is composed by the substances body and mind, whereas the body belongs to the physical world and the mind to the nonphysical world. Rene Descartes was a relevant defender of substance dualism, from his point of view, the body has a presence in the material space, meaning it exist and occupies the physical world while our thoughts and feelings exist in our mind and are not perceivable in the material or physical world. For Descartes, this two substances, material and immaterial "interact with each other at some point in the body", but are distinct objects because they have different properties.
John Searle, on the side, recognizes the substance dualism from the supervenience theory, - even if sometimes he claims

This term paper will explain the life, times, and critical theories of Rene Descartes who is one of the most significant thinkers who ever inquired into the connection between mind and body. It will also explain how culture and period influenced his ideas. Also, it will identify and evaluate the key concepts and analyzes that comprised Descartes' theories. Furthermore, it will detect and describe Descartes' contributions to the field of philosophy as discussed below. The key concepts and analysis that comprises his theories that include the theory of sense perception and the theory of ideas which he mostly concentrates on. According to Descartes' ontology, there are three levels of being which are mode attribute and substance.. The levels of being are agreed regarding ontological requirement, Modes rely on attributes of their being in a way that those same attributes do not depend on methods used and but to rely on the substances for their being in a way that elements do not depend on characteristics. The spirit or nature of a mind, Descartes says, is to think. If a thing does not have faith in, it is not a mind. In his analytical, this very feature of Descartes' theory of ideas, Vere Chappell introduced the terminology of “counterparts” (Chappell, 1986).

Pros And Cons Of Cartesian Dualism

...The correspondence between philosopher René Descartes and the Princess Elisabeth of Bohemia from 1643 to 1649 give incredible insight not only into the person of René Descartes but the intricacies of his philosophical views, particularly as a critical review of his substance dualism. The core tenants of Cartesian dualism are (in brief) that; 1) There exists only two distinct types of substance; material substances (of the body and the physical realm – that is extended spatially) and immaterial substances (that make up the mind, rationality and the soul.) 2) In relation to the body – Descartes is a mechanist; such that the body operates like a machine, according to internal laws, reactivity to external stimuli. The soul or mind is capable of diverting these automated principles; such that we see the distinction between human reason and action, and the behaviour of animals....

Rene Descartes: Mediations on First Philosophy

...2014 Rene Descartes: Mediations on First Philosophy Rene Descartes, known as one of the most influential philosophers of his time, is famously quoted to have been proven the existence of himself with the infamous statement, Cogito ergo sum or (in English) I think, therefore I am. Rene Descartes has claimed to have proven his own existence in this world by claiming that he is in fact a thinking thing, and that therefore he must be something that exists. This raises the question, how can Descartes truly prove to us that in fact he thinks, and how can he prove that since he thinks he therefore can say that he exists? In this essay I will be explaining the reasoning’s of proof as to why Descartes says that he thinks and that therefore he exists, and I will give sufficient support as to why Rene Descartes is in fact correct about his claims that he has stated in his Philosophy of Mediations. The evidence that I will be providing in support for Descartes statement I think, therefore I am include, Descartes doubtfulness of all things he once believed to be true (which he says has been false lies to have been told to him all of his life) (A. w. Bailey, First Philosphy, Second Edition 26-28), secondly his three proofs for his skepticism mentioned in the first piece of evidence listed previously (Descartes asking if he is dreaming or if he is really awake, his painters argument of how dream like/ images arise from real things, and an evil like demon trying to trick Rene Descartes into...

Mind and Body

...following dialogue will present the position of René Descartes and John Searle regarding the mind and body debate. Descartes: It is certainly obvious that the mind and body are two distinctly different entities. The body has physical properties whereas the mind is nonphysical. John: With all due respect Mr. Descartes, I can’t say that I fully agree with your proclamation. However, I would say that the mind is a biological state of the mental that can cause or be caused by physical changes to the body. I feel like you do not have sufficient justification of the relationship of the body and mind (Searle, 2004). Descartes: Well young man, let me explain a few things that will support my premise in a substantial way that may indeed change your position. First of all, the mind can exist without the present of the body. You see John; the existence of my body is dubitable whereas my mind is not. Therefore my mind does not consist of the same properties of my body. This is a clear distinction that my mind is separate from my body. John: Mr. Descartes, we can agree to disagree with some matters of the mind and body. I am troubled that many people think that they have a mind or soul and a body. I am also concerned that some people think they have all three. (Searle, 2004). Western Philosophers are often portraying some type of dualism and people have accepted this theory for many years. Descartes: And rightfully so Mr....

Describe and Assess Dualism as a Theory of the Relation of Mind and Body.

...assess dualism as a theory of the relation of mind and body. Human beings are material objects. However, unlike other material objects (e.g. non-living things) humans have the ability to form judgements and reason their existence. Meaning to say that, human beings have 'minds'. In general, humans are characterised as having both a mind and body.  By definition, mind is referred to the mental processes, thought and consciousness whereas body is referred to the physical aspects of the brain-neurons and how the brain is structured. This is known as dualism.  In the philosophy of mind, dualism is the theory that the mental (mind) and the physical (body) are both real or exist, but both of them are different kinds of thing. The theory of mind-body dualism is presented by Rene Descartes (1596-1650), who holds that both mind and body are substances, in which the body is a material substance as it is extended in space whereas the mind is an unextended in space, and so called spiritual substance. According to Descartes, he believed that mind and body actually can interact through the pineal gland in the brain. In Descartes’s first principle of philosophy, “I think, therefore I am”, makes mind more certain than matter. It also showed that the mind which is a thinking thing can exist apart from its extended body. Hence, Descartes said that the mind is a substance that is different from the body (a substance whose essence is thought). This became known as “Substance Dualism” (view...

The True Nature of Reality

...describing the nature of our reality, philosophers have been in search of a system that truly and completely explains everything. It is noteworthy that numerous system have developed over the past few centuries. However, in this paper only four notable theories (dualism, materialism, idealism and transcendental idealism) will be explored. Each theories provide adequate explanation of reality but there are limitations and shortcomings when one contemplate carefully. The theories will be explored and critique by using the mind body problem, The Chinese room, the radical emergence theory. Moreover, one should consider which theory describes the nature of reality with least logical incoherencies. Substance Dualism is a theory that describes “mind and matter” as “two distinct things” (Nagel Thomas 206). Furthermore, substance dualism categorize matter as “physical or material substance” and mind or soul as “non-physical or immaterial substance” (Lacewing Michael) “Substance Dualism”). So, dualism is the proposal that human being as a living, thinking entity not only includes brain and physical matter but also a non-physical substance to account for the mind. The famous seventeenth century French philosopher René Descartes claimed that as “a subject of conscious thought and experience, he cannot consist of spatially extended matter”. He therefore states that “his essential nature must be non-material, even if in fact his soul is intimately connected with his body” (qtd in.Nagel Thomas...

Cartesian Dualism

...Many would argue between the existence of the mind-body. One may say that the mind and body are two separate entities with distinct characteristics (Dualism). While on the other hand, some may say that there exists only one entity (Monism). The mind represents mental processes such as thoughts and consciousness. The body represents physical aspects of the brain, such as neurons and the formality of the brain. The debate over the mind-body existence have been constant through the teachings and influences of intelligent philosophers. Rene Descartes’ Meditation on First Philosophy, he states that there exists two different entities the mind and body and that they both interact with each other.

Rene Descartes

...Rene Descartes When the term modern philosophy is mentioned, it is usually to make a distinction from ancient and medieval philosophy therefore it does not only mean the philosophy of the 21st century, it means, the philosopher Rene Descartes. Therefore in practice what the term, modern philosophy means is, philosophy from Descartes onwards. He was best known for his quote, ‘Cogito ergo sum’ (I think, therefore I am). Descartes was born on March 31st 1596, in La Haye, a small town in France. He was educated in classics, logic and the philosophy of Aristotle at the Jesuit college of Henri IV in La Fleche. After he graduated he studied at the University of Poitiers, obtaining his law license in 1616. He then joined the army and during his spare time he studied mathematics (Gaukroger and Hall, 1995). In 1619, he experienced the series of powerful dreams, which influenced him greatly in his pursuit of science and knowledge, and he acknowledged this ass his focal point of his life (Gaukroger and Hall, 1995). Descartes spent time in various parts of Europe before he settled in Dutch Republic. He maintained his studies and lived in various places throughout the Republic. During this time, he began his writing career, and he started to publish his new works that would revolutionize mathematics and philosophy, these works included the world, meditation of first philosophy, principles of philosophy and passions of the soul. His mathematical theories provided the basis for the...

Descartes Mind and Body

...Descartes’ Mind Body Dualism Rene Descartes’ main purpose is to attempt to prove that the mind that is the soul or the thinking thing is distinct and is separate from the body. This thinking thing was the core of himself, which doubts, believes, reasons, feels and thinks. Descartes considers the body to be an extended unthinking thing; therefore it is possible that one may exist without the other. This view is known as mind-body dualism. He believes that what he is thinking in his mind is what God created and instilled in him. Descartes outlines many arguments to support and prove his claims of his discoveries. He states that because he can think, his mind exists. This is known as the Cogito, which is the first existential principal of all of Descartes’ work where modern philosophy begins. Descartes also explains that it is possible that all knowledge of external objects, including his body could be false because of the deceiving actions of an evil genius. The evil genius could make him contemplate his existence of his nature as a thinking thing. Descartes further explains in his arguments, even physical objects, such as the body, are better and more distinctly known through the mind than through the body. Descartes shows this through his example of The Wax Argument, where solid wax transitions into liquid state. With all of this in mind, Descartes theories suggest the mind and body can exist separately but it can be argued, the mind needs the body in order to think and reason...

Dualism Research Paper

...For centuries, philosophers have been contemplating the relationship between the body and the mind, creating a major conflict amongst theorists. Dualism is a theory that claims that the mind, a non-physical substance, is completely separate and distinct from the body, a physical substance. Originally coined by the famous philosopher René Descartes, dualism has since been argued against and overshadowed by numerous opposing theories. This was primarily due to the many weaknesses that dualism faced and the problems that could not be explained under this view. One of the opposing theories, functionalism, did not face the weaknesses that dualism did, and the problems they came across were not an issue for functionalists. This view, most strongly...

Mindand Body

...The relationship in between mind and body, the idea of monism and dualism, the connection of mind and body being separate or one had been a debate for centuries. According to Gurung (2013) throughout history of most cultures, there has been the debate of separation in between body and the spiritual mind. The views are not only religious, but also in philosophical approach, going back to 17th century, when Rene Descartes presented the dualism version of mind and body. According to Descartes (1952), “human beings consisted of two quite unlike substances which could not exist in unity” (p1). Descartes’s explanation of mind-body dualism explains that it is natural that our conscious experiences are completely separate from physical and non-living things. According to Gurung (2013) “there are many different cultural approaches to health, and it is important to acknowledge that many cultural variations exist within ethnic communities” (p. 14). Culture has a big debate on how health is incorporated to the mind-body. Different cultures have different believes and health behaviors and expectations from current country they live in. For example a person living in US vs a person living in India with the same health issue have different expectations and understanding of the health issue and the health system. According to Gurung (2013) one health approach used in western medicine that focuses on biology and psychology underlying health is the biopsychosocial approach. Biopsychosocial...

...FEDERAL UNIVERSITY OYE-EKITI, EKITI STATE, NIGERIA. A TERM PAPER TITLE:- “THE ESSENCE/SUBSTANCE OF MAN” BY FACULTY: SCIENCE DEPARTMENT: MICROBIOLOGY COURSE TITLE: PHILOSOPHY AND LOGIC COURSE CODE: GST 205 CONTENT * Introduction * What is man * Philosophically * Scientifically * The essence and substance of man * What constitute man * Man as a dualist * Man as a monad * Man as a socialist * Man as a spiritual entity * Man as a physical entity * Intrinsic characteristics that man have in common * Illustration of the mental essence(when man is abnormal is he still half or full) INTRODUCTION The essence of man is the constituent of man which goes beyond his body alone but extends to his mind, soul, spirit and other attributes of man. But we cannot talk about the essence of man without the existence of man because without an existence of man, man’s essence is of no use and nothing to talk about. This brings about the proposition ‘existence precedes essence’. The proposition that existence precedes essence is a central claim of existentialism, which reverses the traditional philosophical view that the essence (the nature) of a thing is more fundamental and immutable than its existence (the mere fact of its being). To existentialists, human beings—through their consciousness—create their own values and determine a meaning for their life because the human being does not possess any inherent identity or value. By posing the acts that constitute...

Descartes on the Distinction Between Body and Mind

...Name Tutor Course Date Descartes Premise for Distinguishing Body and Mind In the Meditations on First Philosophy, Descartes discusses the nature of the body and mind. By drawing from three lines of thought, Descartes launches a powerful premise that the body is something distinct from the mind. He conceptualizes his argument by using the uncertainty of knowledge argument, appealing to God’s omnipotence, and describing the indivisibility of the body and mind. Therefore, the purpose of this paper is to discuss and analyze Descartes’s premise for distinguishing the body and mind. In the first Meditation, Descartes begins by discussing a topic that seems far removed from the subject, yet instrumental to his argument. He questions the certainty of reality or truth of worldly opinions. In meditations 1.5, he notes that his opinions about the world are based on senses and argues that he cannot be certain that his senses deceive him. He argues that he cannot be sure that what he thinks of as his perceptions of the world are not dreams (Cress 36). Because there is no mechanism for distinguishing sleep from wake, Descartes says that he is also uncertain about the existence of the body. In addition, he argues that an evil demon may be deceiving him about the existence of the sky, air, colors, sounds, and bodies yet such things are illusions of dreams (Cress 41). By reflecting on the scenario of the evil demon and dreaming, Descartes doubts whether external things such as the body...
