Political Realism and Human Interests

Abstract

Although political realism is often understood as a more or less homogeneous tradition fixed on certain essential concepts, John Herz's provocative piece prompts an attempt to examine realist scholarship in a way that reveals some deep antinomies: some internal tensions that make realist scholarship, at least potentially, an evolving, open-ended “dialogue.” Specifically, Jürgen Habermas's categories of knowledge-constitutive interests—practical, technical, and emancipatory—are employed to distinguish two opposed aspects of the realist dialogue: practical realism and technical realism. Practical realism is guided by a practical cognitive interest in sustaining intersubjective understanding within the context of tradition. Its corresponding approach to inquiry and grounding is hermeneutic. Technical realism is guided by a technical cognitive interest in coming to grips with objective laws so as to expand powers of technical control over an objectified reality. Its approach to inquiry and grounding is essentially positivistic. Against this background, Herz's contribution to the realist dialogue is that, unique among realists, he brings a strong commitment to an emancipatory cognitive interest—an interest in self-reflection as the basis for the autonomous expression of will and consciousness in the human species' “self-formative process.” Interpreted in this light, Herz is seen to employ a two-sided discursive strategy, each side addressed to one of realism's two aspects, the practical and the technical. However, though brilliant in conception, Herz's argument is unlikely to be persuasive if realist scholars are at base positivist scientists oriented by a technical interest in control. In this sense, Herz's piece represents a critical “test” of realism, its essence, and its developmental potential.
