Physicalism, or the idea that everything, including the mind, is physical is one of the major groups of theories about how the nature of the mind, alongside dualism and monism. This viewpoint strongly influences many ways in which we interact with our surrounding world, but it is not universally supported. Many objections have been raised to various aspects of the physicalist viewpoint with regards to the mind, due to apparent gaps in its explanatory power. One of these objections is Frank Jackson’s Knowledge Argument. This argument claims to show that even if one has all of the physical information about a situation, they can still lack knowledge about what it’s like to be in that situation. This is a problem for physicalism because physicalism claims that if a person knows everything physical about a situation they should know everything about a situation. There are, however, responses to the Knowledge Argument that patch up physicalism to where the Knowledge Argument no longer holds.
Physicalism, to further specify, states that everything is dependent upon the physical world, and that there is nothing over and above the physical world. It states that everything can be defined in purely physical terms. This view has many implications, especially within the philosophy of mind, where it stands in stark contrast to dualism which puts the mind above the physical world. This focus on the philosophy of mind is, in part, due to it producing most of the objections that appear against physicalism. Within the philosophy of mind, physicalism states that all mental states can be equated to some physical state. Note that this does not necessarily imply the identity hypothesis, or the idea that a specific mental state is associated with a spe...

...s like to experience something. In its original formulation, the ability hypothesis claims that knowledge of what it is like to experience something is knowledge of how to imagine that experience. It is easy enough to think of a person who is incapable of imagining, but whenever they are actively experiencing something, e.g. the color red, they clearly must know what it is like to experience that thing, and yet they have no capacity to imagine that same experience. Clearly, if the ability hypothesis is correct, the definition of knowing what it is like to experience must be improved.
Many refinements of this concept have been put forth by various authors. One simple one that appears to improve greatly upon the original formulation is that knowing what it is like to have an experience is equivalent to the ability to recognize that experience by its phenomenal quality.
Frank Jackson begins his article by writing about what he feels to be a fatal flaw in physicalism. He writes a story about a girl named Mary who is raised in a black-and-white room. In this room Mary was taught everything there is to know about the physical world. The only catch is she learned only from media, which was black-and-white, so she knows nothing of the colors outside this room. After learning everything about the physical world, she is then given the chance to see color. She will then "learn" what color is in the world. For this reason Jackson believes physicalism to be false.
Jackson’s Knowledge Argument, while relying on the validity of epiphenomenalism, manages to stand to arguments of physicalism. The ability of conceivable ‘zombies’ to register qualia without experiencing it responds to the claims of acquaintance arguments. Furthermore, beliefs that qualia would provoke physical changes and reactions are accompanied by flawed assertions of attempting to capture the nature of causation. Qualia and the necessity of non-physical knowledge to their existence provide valid arguments to upholding dualist beliefs.
Richard Taylor explained why the body and the mind are one, and why they are not two separate substances. In the article “The Mind as a Function of the Body”, Taylor divides his article in a number of sections and explains clearly why dualism, or the theory that the mind and the body are separate is not conceivable. In one of these sections it is explained in detail the origin of why some philosophers and people believe in dualist metaphysics. As stated by Taylor “when we form an idea of a body or a physical object, what is most likely to come to mind is not some person or animal but something much simpler, such as a stone or a marble”(133). The human has the tendency to believe a physical object as simple, and not containing anything complex. A problem with believing this is that unlike a stone or a marble a human (or an animal) has a brain and the body is composed of living cells (excluding dead skin cells, hair, and nails which are dead cells). The f...
The mind-body problem can be a difficult issue to discuss due to the many opinions and issues that linger. The main issue behind the mind-body problem is the question regarding if us humans are only made up of matter, or a combination of both matter and mind. If we consist of both, how can we justify the interaction between the two? A significant philosophical issue that has been depicted by many, there are many prominent stances on the mind-body problem. I believe property dualism is a strong philosophical position on the mind-body issue, which can be defended through the knowledge argument against physicalism, also refuted through the problems of interaction.
Are minds physical things, or are they nonmaterial? If your beliefs and desires are caused by physical events outside of yourself, how can it be true that you act the way you do of your own free will? Are people genuinely moved by the welfare of others, or is all behavior, in reality, selfish? (Sober 203). These are questions relevant to philosophy of the mind and discussed through a variety of arguments. Two of the most important arguments with this discussion are Cartesian dualism and logical behaviorism, both of which argue the philosophy of the mind in two completely different ways. Robert Lane, a professor at the University of West Georgia, define the two as follows: Cartesian dualism is the theory that the mind and body are two totally different things, capable of existing separately, and logical behaviorism is the theory that our talk about beliefs, desires, and pains is not talk about ghostly or physical inner episodes, but instead about actual and potential patterns of behavior. Understanding of the two arguments is essential to interpret the decision making process; although dualism and behaviorism are prominent arguments for the philosophy of the mind, both have their strengths and weaknesses.
The 'mind-body' problem has troubled philosophers for centuries. This is because no human being has been able to sufficiently explain how the mind actually works and how this mind relates to the body - most importantly to the brain. If this were not true then there would not be such heated debates on the subject. No one objects to the notion that the Earth revolves around the sun because it is empirical fact. However, there is no current explanation on the mind that can be accepted as fact. In 'What is it like to be a bat?', Thomas Nagel does not attempt to solve this 'problem'. Instead, he attempts to reject the reductionist views with his argument on subjectivity. He examines the difficulties of the mind-body problem by investigating the conscious experience of an organism, which is usually ignored by the reductionists. Unfortunately, his arguments contain some flaws but they do shed some light as to why the physicalist view may never be able to solve the mind-body problem.
With such direct perception in mind, Gibson (1966) coined the term “affordances,” which are q...
Physicalists believe in the philosophical position that everything, which exists, is no more extensive than its physical properties, and that the only existing substance is physical (Mastin 2008). Another term used to describe two-way interactive substance dualism is Cartesian dualism, which was defended by Descartes. Cartesian dualism is the idea that mind is not the same thing as matter, although they do causally affect each other.
Fodor begins his article on the mind-body problem with a review of the current theories of dualism and materialism. According to dualism, the mind and body are two separate entities with the body being physical and the mind being nonphysical. If this is the case, though, then there can be no interaction between the two. The mind could not influence anything physical without violating the laws of physics. The materialist theory, on the other hand, states that the mind is not distinct from the physical. In fact, supporters of the materialist theory believe that behavior does not have mental causes. When the materialist theory is split into logical behaviorism and the central-state identity theory, the foundation of functionalism begins to form. Logical behaviorism states that every mental feeling has the same meaning as an if-then statement. For example, instead of saying "Dr. Lux is hungry," one would say "If there was a quart of macadamia brittle nut in the freezer, Dr. Lux would eat it." The central-state identity theory states that a certain mental state equals a certain neurophysiological state. The theory works in a way similar to Berkeley’s representation of objects. Both mental states and objects are a certain collection of perceptions that together identify the particular state or object.
Dualism claims that the mind is a distinct nonphysical thing, a complete entity that is independent of any physical body to which it is temporarily attached. Any mental states and activities, as well as physical ones, originate from this unique entity. Dualism states that the real essence of a person has nothing to do with his 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.
. There are two kinds of dualism. One is Substance dualism which holds that the mind or soul is a separate, non-physical entity, but there is also property dualism, according to which there is no soul distinct from the body, but only one thing, the person, that has two irreducibly different types of properties, mental and physical. Substance dualism leaves room for the possibility that the soul might be able to exist apart from the body, either before birth or after death; property dualism does not. A substance dualism is something with "an independent existence". It can exist on its own. This holds that each distinct non-physical entity mind composed a different kind of substance to material objects. Substance dualist believed only spiritual substances can have mental properties. It is “soul” along with certain memory and psychological continuities that constitutes the survival of the person. Physical properties of property dualism are properties like having a certain weight, conducting electricity and mental properties are properties like believing that 1+1=2, being in love, feeling pain, and etc. Property dualism allows for the compatibility of mental and physical causation, since the cause of an action might under one aspect is describable as a physical event in the brain and under another aspect as a desire, emotion, or thought; substance dualism usually requires causal interaction between the soul and the body. Dualistic theories at least acknowledge the serious difficulty of locating consciousness in a modern scientific conception of the physical world, but they really give metaphysical expression to the problem rather than solving it.
Functionalism is a materialist stance in the philosophy of mind that argues that mental states are purely functional, and thus categorized by their input and output associations and causes, rather than by the physical makeup that constitutes its parts. In this manner, functionalism argues that as long as something operates as a conscious entity, then it is conscious. Block describes functionalism, discusses its inherent dilemmas, and then discusses a more scientifically-driven counter solution called psychofunctionalism and its failings as well. Although Block’s assertions are cogent and well-presented, the psychofunctionalist is able to provide counterarguments to support his viewpoint against Block’s criticisms. I shall argue that though both concepts are not without issue, functionalism appears to satisfy a more acceptable description that philosophers can admit over psychofunctionalism’s chauvinistic disposition that attempts to limit consciousness only to the human race.
While the great philosophical distinction between mind and body in western thought can be traced to the Greeks, it is to the influential work of René Descartes, French mathematician, philosopher, and physiologist, that we owe the first systematic account of the mind/body relationship. As the 19th century progressed, the problem of the relationship of mind to brain became ever more pressing.
Impressions are given sensations that arise from "unknown causes". Remember that what we know are our impressions, according to this trend. Whether there is something that corresponds to these impressions is unknown, for we don't know real being, we know impressions (a la Descartes).
But, “human persons have an ‘inner’ dimension that is just as important as the ‘outer’ embodiment” (Cortez, 71). The “inner” element cannot be wholly explained by the “outer” embodiment, but it does give rise to inimitable facets of the human life, such as human dignity and personal identity. The mind-body problem entails two theories, dualism and physicalism. Dualism contends that distinct mental and physical realms exist, and they both must be taken into account. Its counterpart (weak) physicalism views the human as being completely bodily and physical, encompassing no non-physical, or spiritual, substances.
