Most of us interchange substance dualism with Cartesian dualism, physical substance and spiritual substance. Thomas Nagel is not a substance dualism but his Property Dualism advocates a duality of mental and physical. But the mental, in this case, is not a substance. It is correct that there is two substances (physical and spiritual), at least in theism as you said, but when it comes to human beings, we are physical with spiritual ends (not elevated to a spiritual substance) and our rational/intellectual ability emerges from our form, not necessarily our brain. If I were to compare it to other dualisms; think of Thomas Nagel’s dualism except with an Aristotelian foundation of form/matter (not explaining properties as accidents) and rational thought emerging from the mental, not the physical, and effecting the physical. It avoids epiphenomenalism (which threatens Nagel’s dualism) and does not propose the human being as an accidental but an ordered species to a final cause. Formal and final causes are the keys, there will always be problems in philosophy of mind and philosophy period until modernists reestablish Aristotelian Four Causes as the main pillar.“Substance dualism is the view that the universe contains two fundamental types of entity: mental and physical.” 1]
“substance dualism - The view that the mental and the physical comprise two different classes of objects: minds and bodies.” 2]
“Substance dualists typically argue that the mind and the body are composed of different substances and that the mind is a thinking thing that lacks the usual attributes of physical objects: size, shape, location, solidity, motion, adherence to the laws of physics, and so on.” 3]
“Substance dualism holds that there are two fundamentally different types of such entities – material substances, or bodies, and mental substances, or minds.” 4]
You said you looked up substance dualism, but all the above are from a 10 second google search. They all agree with me. Where did you look?![]()
