Property dualism
Property dualism is a philosophical perspective that posits a distinction between the physical properties of the brain and the mental properties of the mind. Proponents of property dualism assert that while the brain is made up of physical matter, it possesses both physical characteristics, such as weight and shape, and distinct mental characteristics, such as beliefs and emotions. This view stands in contrast to physicalism, which claims that everything, including mental states, is reducible to physical processes.
Within property dualism, mental properties are considered unique and not merely the byproduct of physical properties, though they argue that mental phenomena arise from the brain's physical complexities. For instance, the sensation of pain is seen as more than just neural activity. Property dualists maintain that mental properties, while caused by the brain, cannot be fully explained by physical science.
There are two main branches of property dualism: epiphenomenalism, which suggests that mental states are effects of physical events but do not influence them, and interactionism, which argues that mental and physical properties can impact each other. The debate surrounding property dualism contributes to the broader philosophical inquiry known as the mind-body problem, which explores the intricate relationship between mental experiences and physical existence.

Property dualism
Property dualism is a philosophical belief that the body, including the brain, is physical, but the mind is spiritual. Property dualists contend that while the brain is made up of a physical substance, it has both physical and mental properties. They believe that the brain is complex enough to produce these mental properties.
Background
For many years, philosophers have referred to the relationship between the body and the mind as "the mind-body problem." They seek an answer to the question, "What is the relationship between the mind and the body, including the brain?" They want to know if thoughts, feelings, and emotions happen in addition to the physical processes of the body or if they are part of these processes. Physicalists and dualists are two main groups of individuals who have tried to answer the question and solve the mind-body problem.
Physicalists believe that the body and the mind are one. Physicalism is the idea that everything in nature is physical and nothing has characteristics that are beyond the physical. Physicalists claim that a mental state—such as pain, anger, or joy—is the manifestation of a physical event, such as a neuron firing, in the brain. Physicalists contend that the physical body is responsible for everything that occurs in the mind, and mental states cannot be separated from the physical in any way.
Dualists, on the other hand, believe that the mind and body are inherently different. Their beliefs are the opposite of physicalists' beliefs. Dualists purport that the mind is, at least in some ways, separate from the body. Two types of dualism exist: substance dualism and property dualism.
Substance dualism suggests that the mind is a different substance from the brain itself. In other words, the brain is made up of substances identified by physics (e.g., atoms), but the mind is made up of another, unknown substance that is independent of the brain. Substance dualists believe this substance is the soul and that the soul can exist when it is separated from the body.
Property dualists suggest that only one type of substance exists in the brain and the mind. They believe the mind is made up of a physical substance that physics can identify—matter and atoms and nothing more. However, property dualists also believe the mind has two types of properties. The brain has physical properties, such as weight, color, and shape. But, the mind also has mental properties, such as desires, beliefs, and consciousness.
Overview/Topic Today
Property dualists contend that mental properties are unique and different from physical properties. For example, they believe that the mental property of pain is more than just the physical property of firing a neuron. But they think these mental properties could not exist without the physical properties. Property dualists contend that mental properties are different from physical properties, but the mental properties are caused by the physical brain.
Science has only just begun to identify the physical complexity of the brain. Property dualists theorize that the complexity of the brain allows mental properties to exist, even though they are not the same as physical complexities.
Property dualists believe that the mental phenomena cannot be reduced to physical phenomena. Although physics can explain the substance of the brain, it cannot fully describe the mental properties of the mind. Property dualism claims that mental properties are fundamental. In other words, these properties cannot be reduced or explained. We know what gravity is and how it works, but we cannot describe what causes gravity because it is a fundamental force. In the same way, property dualists claim that mental properties cannot be fully explained.
The mental properties explained by property dualism can be difficult to explain. Some property dualists compare these properties to properties that can arise in other situations. For example, atoms have no colors. However, when enough atoms join together, they form substances with color and other characteristics. Yet, this comparison is not completely appropriate since the physical property (e.g., color) is not comparable to a mental property (e.g., desire).
Because property dualists believe that the mind is made up of only one substance, they think that when the body dies, the mind dies as well. Since the mental properties are produced by the complicated physical properties, the mental properties are no longer produced after the physical brain dies.
Two different groups of property dualists exist: epiphenomenalism and interactionism. Epiphenomenalism is the belief that mental phenomena are caused by physical events in the brain but mental phenomena are not responsible for any physical phenomena. Most people who argue against epiphenomenalism think that it is clear from everyday life that our mental states (e.g., hunger, pain, and desire) impact our physical actions. For example, a person who is hungry sees an apple, reaches for the apple, and eats it. However, epiphenomenalism claims that no one can truly say what causes something to happen. For example, a barometer falls before a storm occurs. The falling barometer always occurs before the storm, but the falling barometer does not cause the storm.
Interactionism claims that physical and mental properties affect each other. For most people, this theory seems to align most closely with the observable world. When a person is hungry, they eat. When a person is hurt, they jumps up and down. The mental properties of hunger and pain cause a physical movement or reaction. However, people with an objection to interactionism believe that it is not possible for a purely mental property to impact a purely physical property.
