Positivism, Historicism, and Political Inquiry

The present controversy between “behavioral” and “postbehavioral” views of political inquiry reflects a larger dispute between two opposing theories of knowledge. Whereas the behavioral movement has its epistemological roots in positivism and, ultimately, in classical British empiricism, the most recent protest against behavioralism draws upon the theory of knowledge that has been the principal foe of empiricism over the past century. This theory of knowledge, which received the name “historicism” shortly after its emergence, had become the dominant epistemological position by the mid-twentieth century. This essay considers the general nature of historicism and its influence on the recent revolt against positivism in the philosophy of science. Finally, it examines the use that political scientists have made of historicist principles in opposing positivistic models of political inquiry. It argues that an epistemological relativism becomes unavoidable once certain premises of historicism are embraced.
