Steff: It’s time to explore Dualism. I’m under the impression it’s something to do with the mind and body… So, Sophi, can you explain this please?
Sophi: Yes, of course.
Dualism, in philosophy, is the theory that the mental and the physical—or the mind and the body, or the mind and the brain—are, in some sense, radically different kinds of things. Essentially, it suggests that there are two fundamental kinds of substance that exist independently and make up the universe: the mental and the physical, or the immaterial and the material.
This concept has been explored by the ancient Greek philosopher Aristotle and famously articulated by René Descartes, a 17th-century French philosopher. Descartes’ dualism, often referred to as Cartesian Dualism, posits that there is a clear division between the realm of the mind (which is unextended and immaterial) and the realm of the body (which is extended and material). According to Descartes, these two realms interact with each other but have fundamentally different natures.
The mind-body dualism raises various philosophical issues, especially concerning how the immaterial mind can have any effect on the physical body and vice versa. This interaction problem is a major topic of debate in the philosophy of mind.
Dualism contrasts with various forms of monism, which hold that everything is composed of the same kind of substance. The two primary forms of monism are physicalism (or materialism), which holds that only the physical is real, and idealism, which posits that only the mental is real.
In contemporary discussions, dualism is often contrasted with the view that mental states are identical to physical states in the brain, a position known as physicalism or materialism. These debates are central to modern philosophy of mind, as they relate to many other issues such as consciousness, free will, and the nature of identity.
