Supervenience introduction
Supervenience A-properties supervene on the B-properties. If you fix the B-properties, you thereby fix the A-properties. The B-properties determine the A-properties. The A-properties are nothing over and above the B-properties.
Supervenience Mental-properties supervene on the physical-properties. If you fix the physical-properties, you thereby fix the mental-properties. The physical-properties determine the mental-properties. The mental-properties are nothing over and above the physical-properties.
Individual Supervenience Two individuals are A-duplicates iff they have all the same A-properties. A-properties individually supervene on B-properties iff, necessarily, any individuals that are B-duplicates are also A-duplicates.
Physicalism First Attempt: Physicalism is the view that mental properties individually supervene on physical properties. Necessarily, any individuals that are physical duplicates are also mental duplicates.
Possible Worlds A statement is something that is true or false. A set of statements is consistentiff all of the members could be true together. A set of statements is completeiff, for any statement S, either S or not-S is a member of that set. A possible world is a consistent and complete set of statements.
Possible Worlds A statement is necessarily true iff it is true in all possible worlds. A statement is possibly true iff it is true in some possible world. One statement entails another iff every possible world where the first is true is one in which the second is true.
Global Supervenience A-properties individually supervene on B-properties iff, necessarily, any individuals that are B-duplicates are also A-duplicates. A-properties globally supervene on B-properties iff, necessarily, any possible worlds that specify the same distribution of B-properties will specify the same distribution of A-properties.
Physicalism Second Attempt: Physicalism is the view that mental properties globally supervene on physical properties. Any two possible worlds that specify the same distribution of physical properties will specify the same distribution of mental properties.
