Is Anti-Rationalism Rational? The Case of F. A. Hayek

Abstract

The theme addressed is the criticism of constructivism and rationalism in politics as presented in the political theory of F. A. Hayek. Hayek's thesis is that goal-directed rationality in politics is counter-final. The main argument of this article is that on closer examination Hayek appears to be a constructivist himself. The purpose of Hayek's anti-rationalism is primarily ideological and instrumental. Hayek wants to induce certain anti-rationalistic beliefs because he believes rationalism has bad consequences. Yet this very project can be considered a case of goal-directed rationality. Furthermore, the argument is that Hayek mixes abstract philosophical doctrine with empirical theory. In his critique of constructivism, Hayek confuses two notions of ‘rationality’. On the one hand he argues against epistemological rationalism associated with Descartes, and on the other he argues against the subjectivistic, action-oriented notion of ‘rationality’ associated with the idea of ‘economic man’. Arguments against Cartesian rationalism do not, however, imply the impossibility of goal-directed rationalism in politics. The so-called information problem cannot be solved at an epistemological level. It is a practical problem, which Hayek has certain ideas how to solve. The argument here, therefore, is that Hayek's thesis of ‘tacit knowledge’ is not an expression of skepticism as is often believed.
