Explain the concept of functional individuation in functionalism.

Functional individuation in functionalism refers to the idea that the identity or individuality of a mental state or process is determined by its functional role or the role it plays within a larger system. According to functionalism, mental states are not defined by their physical properties or the specific physical processes that give rise to them, but rather by their causal relations to other mental states and external stimuli. This means that two mental states can be considered the same if they perform the same function or have the same causal role, even if they are realized by different physical processes or substrates. Functional individuation emphasizes the importance of the functional organization and relationships within a system in determining the identity of mental states, rather than their specific physical properties.
