For any artefact that we might build which had mental states equivalent to human mental states, the implementation of a computer program would not by itself be sufficient. Rather the artefact would have to have powers equivalent to the powers of the human brain. (p. 41)
First, how is consciousness possible? ...[T]here are certain specific electrochemical activities going on among neurons... and these processes cause consciousness....
[S]econd... how can atoms in the void have intentionality?... [E]xperiences... are all caused by brain processes and they are realised in the structure of the brain, and they are all intentional phenomena....
Our third problem: how do we accommodate the subjectivity of mental states within an objective conception of the real world? ...My present state of consciousness is a feature of my brain, but its conscious aspects are accessible to me in a way that they are not accessible to you.... Thus the existence of subjectivity is an objective fact of biology....
