Dualism Essays - Ontology, Philosophy Of Mind, Mindbody Problem

Dualism I believe that the popular or "ghost in the machine" form of substance dualism best solves the mind body problem. My views in this area have been influenced by my twelve years of Catholic education. The soul, or mind, depending on your level of belief, was a complete and separate entity and was the center of a human being. The body was an ambulatory device that the soul directed. The idea that the mind is a separate entity and that it is independent of the physical body is the central point of substance dualism. Churchland explains that substance dualism claims that the mind is a distinct nonphysical thing, a complete nonphysical entity that is independent of any physical body to which it is temporarily attached. Any and all mental states and activities, as well as physical ones, originate from this unique entity. Substance dualism states that the real essence of you has nothing to do with your physical body, but rather from the distinct nonphysical entity of the mind. The mind is in constant interaction with the body. The body's sense organs create experiences in the mind. The desires and decisions of the mind cause the body to act in certain ways. This is what makes each mind's body its own. The popular or "ghost in the machine" form of substance dualism states that a person is a "ghost in a machine", the ghost being the mind or spirit and the machine is the body. Within this description, the mind/spirit controls the body and is in intimate contact with the brain. The brain would be the nexus between the mind and body. The popular form of substance dualism was adopted after the difficulties of Cartesian dualism could not be overcome. Rene Descartes stated that the nonphysical and the physical could not interact. This became a problem in dualism since the nonphysical mind needed to interact with the physical body. These difficulties provided a motive for the move to popular substance dualism. The first major argument for substance dualism is religion. Each of the major religions place belief in life after death that there is an immortal soul that will survive death. This very closely resembles substance dualism. The mind can be substituted for the immortal soul. In fact the two are almost interchangeable. This argument is primarily the basis for my own belief in substance dualism. My personal experiences as a religion student give me insight into this argument. The second major argument for substance dualism is irreducibility. This points to a variety of mental phenomena that no physical explanation could account for what is going on. An example would be the quality and meaningful content of human thoughts and beliefs. These things cannot be reduced to purely physical terms, hence irreducibility. This is also another good argument that I can understand from personal experiences. I cannot reduce my reactions and feelings toward how a steak tastes to a mathematical equation. This is the same idea. The final argument for substance dualism is parapsychological phenomena. Mental powers such as telepathy, precognition, telekinesis, and clairvoyance are all near impossible to explain within the boundaries of physics and psychology. These phenomena reflect the nonphysical and supernatural nature that dualism gives to the mind. Because I believe in these phenomena, it seems logical to me that parapsychology is an excellent argument for substance dualism. These arguments give a good basis for a philosopher to believe in substance dualism. However there are also serious arguments against it. The first major argument against dualism is simplicity. Materialists state that because their view is simpler (they only believe in one thing- that which is physical) it is more rational to subscribe to their view. The materialist point of view is also easier to prove because there is no doubt that physical matter exists, while nonphysical matter is currently a hypothesis. This argument seems very illogical to me. Philosophical views should be chosen because one makes more sense to you, not because one has a smaller number of ideas within it. The second major argument against substance dualism is explanatory impotence. Materialists can explain anything physical through scientific study, whereas dualists can explain nothing because no theory has ever been formulated. Churchland says, "...dualism is less a theory of mind than it is an empty space waiting for a genuine theory of mind to be put in". I see one flaw with the materialist theory here. The mind in the dualist theory may use a form of energy transfer not yet discovered by science. Centuries ago, undiscovered forms
