+**Functionalism** is a theory in the philosophy of mind proposing that mental states are defined by their causal relations to other mental states, sensory inputs, and behavioral outputs, rather than by their physical composition. It views the [Mind](/wiki/Mind) as a system of functions, much like software can run on different hardware. This perspective offers a robust framework for understanding [Cognition](/wiki/Cognition) across various systems.
