Objections to Descartes’ Interactionism

To what extent if any is Descartes successful in showing there is a real distinction between mind and body

René Descartes believed that the mind and body are separate; that the senses could not always be trusted, but that because we as humans are able to think about our existence, we possess some sort of entity separate than our fleshly body. I believe this separate entity to be a soul”an immaterial and

In this paper, I will discuss the “Divisibility argument” on Descartes mind- body dualism presented on Descartes meditations. I will claim that the mind and the body are in fact different as Descartes argument suggests, but I will more rather neglect and explain why his belief that the mind is indivisible is wrong. I also will discuss how Descartes argument on the body’s divisibility is reasonable, and the reasons why I believe this argument is true.

The mind is a complex myriad of thoughts and psychological systems that even philosophers today cannot entirely grapple. It is composed of the senses, feelings, perceptions, and a whole series of other components. However, the mind is often believed to be similar or even the same as the brain. This gives rise to the mind-brain identity theory, and whether there exists a clear distinction between the physical world and the non-material mind. In this paper, I will delineate the similarities and differences between mind and brain, describe the relevant ideas such as functionalism and materialism, and provide explanations on how these theories crystallized. Further, I will discuss the differing views of this concept from multiple philosophers’ perspectives and highlight the significance of each. Ultimately, I will defend the view that the mind-brain identity theory is false by analyzing its errors and examining the invalid assumptions it makes about consciousness.

For one to begin the quest into Descartes’ dualism, one must first look at the argument of the real distinction. In Descartian thought, the “real distinction”

What is the mind-body problem? The mind-body problem asks the question, are the mind and body separate substances of elements of the same substance? In this paper I wish to propose, and try to provide support for Descartes notion of the immaterial mind, by critically discussing the view of substance dualism, pertaining to the relationship between the mind and body. The two arguments of which I will provide in this paper to support this view are divisibility and disembodied existence. There are two fundamentally different substances in this universe, physical and mental properties, this paper will explore both of these substances (8).

Like many people today, Descartes believed that the mind and soul were separate. He believed that the mind’s purpose was only for “thinking” and “non-extended” things. While, the body is an extension; non-thinking. Descartes thought that the mind and body were different substances, thus they

Summary: The problem of the soul continues as Descartes suggested that the human is composed of two completely different substances; a physical body which Descartes compares with a machine, and a non-physical mind, related to the soul, that allows humans to think and feel even if it has no “measurable dimensions” (67). But Elizabeth put in doubt his ideologies when she realized that a non-physical thing doesn’t have the strength to push and move the body. This led to several questions unanswered and also let space for other materialist theories such as behaviorism, mind-brain identity, and functionalism, which also fail in offering an explicit solution.

As a thinking entity, Descartes is a consciousness mind aware of the potential to engage in various modes of existence. To the numerous operations of “thought” he includes doubting, understanding, affirming, denying, willing, refusing, imagining, and sensing. As varied and manifold as these operations appear, they are but expressions of two principal types of conscious activity, to which Descartes eventually traces the nature of error. Thinking and reasoning, together with all belief in general, depend upon the operation of the twin faculties “knowing” and “choosing,” or the free will. Garrett Thompson writes:

In Meditation six: Concerning the Existence of Material Things, and the Real Distinction between Mind and Body, Rene Descartes wrote of his distinctions between the mind and the body, first by reviewing all things that he believed to be true, then assessing the causes and later calling them into doubt, and then finally by considering what he must now believe. By analyzing Descartes’ writing, this paper will explicate Descartes’ view on bodies and animals, and if animals have minds. Before explicating the answer to those questions, Descartes’ distinctions between the mind and the body should first be summarized and explained.

The mind is perhaps the most fascinating part of the human body due to its complexity and ability to rationalize. In essence, the mind-body problem studies the relation of the mind to the body, and states that each human being seems to embody two unique and somewhat contradictory natures. Each human contains both a nature of matter and physicality, just like any other object that contains atoms in the universe. However, mankind also is constituted of something beyond materialism, which includes its ability to rationalize and be self-aware. This would imply that mankind is not simply another member of the world of matter because some of its most distinctive features cannot be accounted for in this manner. There are obvious differences between physical and mental properties. Physical properties are publically accessible, and have weight, texture, and are made of matter. Mental properties are not publically accessible, and have phenomenological texture and intentionality (Stewart, Blocker, Petrik, 2013). This is challenging to philosophers, because man cannot be categorized as a material or immaterial object, but rather a combination of both mind and body (Stewart, Blocker, Petrik, 2013). Man embodies mind-body dualism, meaning he is a blend of both mind and matter (Stewart, Blocker, Petrick, 2013). The mind-body problem creates conflict among philosophers, especially when analyzing physicalism in its defense. This paper outlines sound

The mind-body problem is an age-old topic in philosophy that questions the relationship between the mental aspect of life, such as the field of beliefs, pains, and emotions, and the physical side of life which deals with matter, atoms, and neurons. There are four concepts that each argue their respective sides. For example, Physicalism is the belief that humans only have a physical brain along with other physical structures, whereas Idealism argues that everything is mind-based. Furthermore, Materialism argues that the whole universe is purely physical. However, the strongest case that answers the commonly asked questions such as “Does the mind exist?” and “Is the mind your brain?” is Dualism.

When Princess Elisabeth questioned Descartes on the possibility of interaction between heterogeneous substances [AT III 661]., he answered recognizing that through his works, he had not said much about the union of mind and body. In his letter [21-05-1643] Descartes justifies this saying he had been primarily focused in the demonstration of the distinction between mind and body.

and this quantity of motion is “the product of its speed and its size” (Descartes, 1644/2012, p.33), but the conception of speed used by Descartes is an scalar rather than considered as a vector like velocity (as modern development shows (Gerald Holton and Stephen G. Brush , 2001, p. 210)), nonetheless Descartes suggests that “the mind does not directly move the external limbs, but simply controls the animal spirits which flow from the heart via the brain into the muscles, and sets up certain motions in them..” (Descartes, 1641/1985, p. 161), and this allow the interaction of substances in Cartesian terms, in other words, according to Descartes, the soul only change the direction of the body, but cannot add motion to the physical bodies; however, this is the problem of the interaction in Cartesian terms: as Dennett explain “any change in the trajectory of any physical entity is an acceleration requiring the expenditure of energy” (Dennett, 1991, p. 35), thus, the Cartesian explanation should violate the laws of physics, in other words as Dennett asks “…where is this energy to come from?” (Dennett, 1990, p.35), and this energy cannot come from a
