Abstract

Functionalism is a dominant but widely criticized perspective in social theory; my goal in this paper is to help clarify what functionalists claim, identify what would count as evidence for those claims and evaluate some standard criticisms. Functionalism relies essentially on functional explanations of the form "A exists in order to B." I point out problems with previous accounts of such explanations, offer an improved account, and discuss in detail evidence that might confirm such explanations and its difficulties. I argue that some functionalist accounts can be confirmed and that, contra the critics, functionalism's problems are not inherent errors, "only" practical ones
