Causal Theoretical Functionalism Lecture 2.4

These flashcards cover the key concepts, methods, figures, and objections associated with causal theoretical functionalism as presented in the lecture.

Causal Theoretical Functionalism

A branch of functionalism that defines mental states by the specific set of causal powers and causal roles they possess within a theory, rather than purely through computational information processing.

Ramsey-Lewis Method

A method named after Frank Ramsey and David Lewis used to define mental terms by taking a psychological theory, replacing psychological predicates with variables, and using existential quantifiers to describe their roles.

Frank Ramsey

The philosopher who pioneered the method of defining theoretical terms by replacing predicates with variables, which was later adapted for functionalism.

David Lewis

A philosopher who applied the Ramsey method to psychology, advocating for a functionalist account based on common sense psychological terms.

Existential Quantifier

A logical tool used in the Ramsey-Lewis method to specify that there exists a state (represented as $m_1, m_2, m_3$, etc.) that performs the causal role described in the theory.

Common Sense Psychology

The ordinary, everyday language and concepts (such as belief, desire, and intelligence) used by people to describe mental states, which David Lewis used as the basis for his functionalist theory.

Scientific Psychology

An alternative source for functionalist definitions that relies on the theories of trained psychologists rather than everyday common sense language.

Qualia (Qualitative Conscious States)

The phenomenal, subjective experience of sensations and perceptions that critics argue are not adequately captured by functionalist accounts of the mind.

Quality Inversion

An objection to functionalism suggesting that two people could be in functionally equivalent states while having different qualitative experiences, such as one person seeing red where another sees green.

Mad Scientist Objection

A thought experiment involving a neurosurgeon who crosswires brain receptors (e.g., swapping itch and pain) so that while causal reactions and beliefs remain functionally the same, the qualitative tastes or sensations are fundamentally different.
