“Yes, I am a confirmed "dualist" at this point in my journey, i.e., I understand my mind to be separate from my body/brain, analogous to the way an application program and its data are separate from the computing infrastructure they depend on.” - Chasw
Dualism is a commitment to the idea that mind and brain are fundamentally different ontological categories or 'substances'. That creates the problem of mind-body interaction. If mind and brain (body) were fundamentally different, then how could brain-to-mind and mind-to-brain interactions be explained?
Dualists are also committed to minds being separable from brains, not just being separate and different. I don't think the
mind = programme/data
brain = hardware
