Identify the claim that commits an ‘intensional fallacy’, according to the type-identity theorists.

The claim that commits an ‘intensional fallacy’ according to type-identity theorists is the belief that mental states and brain states are not identical because they can be referred to in different ways. This fallacy occurs when one assumes that the meaning or connotation of a term implies a difference in the entities referred to by that term.

Type-identity theorists argue that mental states are brain states, and any distinction made based on different descriptions (intensionality) of mental states does not reflect a true difference in the underlying reality of those states.

In summary, the intensional fallacy arises when one mistakenly believes that the linguistic or conceptual differences between mental states and brain states imply that they are fundamentally different, rather than recognizing that they refer to the same underlying phenomenon.
