Communicative action and the radical constitution: the Habermasian challenge to Hayek, Mises and their descendents

This paper evaluates Jurgen Habermas's typology of action andhis recent call for a radically democratic rule of law. Thetheory of action that Habermas develops, however, differs significantlyfrom the science of action (praxeology) of the Austrian school.As such, it represents a methodological challenge to Austrianpraxeology. Additionally, Habermas's criticism of the welfarestate is shown to be somewhat consistent with Hayek's criticisms,but his alternative to the welfare state challenges the politicalvision of many Austrian economists. This paper attempts to demonstratethat both Habermas's and the Austrian school's efforts sufferfrom similar weaknesses and epistemological pretences.
