Equality and Singularity in Justification and Application Discourses

To respond to the charge of context-insensitivity, discourse ethics distinguishes justification discourses, which only require that we consider what is equally good for all, and subsequent application discourses, in which the perspective of concrete others must be adopted. This article argues that, despite its pragmatic attractiveness, the separation of justification and application neglects the co-constitutive role that applicability plays for the meaning of normativity. Norms that do not, in a machine-like fashion, produce their cases, cannot already contain their appropriateness to the cases that nonetheless alone justify the existence of norms in th first place. The higher-order norm of appropriateness that enters normativity with th dependence on applications is one that remains implicit, and impossible to determine in advance. Thus, the justification of a norm is always incomplete for conceptual and not merely empirical reasons, as fallibilism typically has it.
