Rationality Beyond Instrumental Reason: Reconstructing European Philosophical Traditions

Abstract

The dominant conception of rationality in modern Western thought has been instrumental rationality, a model centrally concerned with the effective pursuit of given ends through appropriate means. This understanding has structured scientific inquiry, economic practice, bureaucratic governance, and social policy since the Enlightenment. Yet the elevation of instrumental rationality has generated deep theoretical and socio-ethical problems, including the reduction of human rational capacities to mere calculative functions, the displacement of moral and communicative forms of reasoning, and the colonization of lifeworld practices by technocratic logic. The goal of this paper is to explore how European philosophical traditions have both produced and transcended instrumental reason, offering reconstructed models of rationality that preserve human freedom, ethical discourse, and normative critique. Drawing on the works of Max Weber, the Frankfurt School (Horkheimer, Adorno), Jürgen Habermas, and other continental figures, we argue that rationality beyond instrumental reason must be grounded in a pluralistic, communicative, and value-oriented conception of reason. This reconstruction not only challenges reductive accounts of practical rationality but also enriches philosophical foundations for democracy, morality, and human emancipation.
