Consciousness is physical
Physicalism is the doctrine that everything is physical. If everything is physical then consciousness is physical as well. So a conscious computer or robot could be built out of physical parts.
PhysicalismJaegwon Kim (1996) takes three principles is defining minimal physicalism:
1)
Mind body supervenience: physical indiscernability entails psychological indiscernability.
2)
Anti-Cartesian principle: There are no purely mental things.
3)
Mind-body dependence: What mental properties a thing has depends on its physical properties.
Note: Other philosophers would describe physicalism differently.
