Functionalism in Philosophy of Mind

Functionalism in the philosophy of mind is the view that mental states are defined by their functions—what they do—rather than by their internal constitution. For example, pain is identified not by how it feels but by its role in producing certain behaviors, like withdrawing from harmful situations. In the context of the "hard problem of consciousness," which asks why and how subjective experiences arise from physical processes, functionalism challenges us to consider how mental functions can exist independently of the specific experiences associated with them, leading to debates about whether this perspective fully addresses the nature of consciousness.
