According to Rainer Forst, a critical theory of power must break with the tendency of political theorists to conceive of power in opposition to normativity. Appropriately, Forst proposes a noumenal definition according to which power is normative: It works through recognition of reasons and is thereby open to critical assessment. In this discussion note, I first clarify the normativity of power in Forst’s noumenal theory by means of Donald Davidson’s theory of action and then explain how theory of action leads (...) to a different understanding of force and violence from Forst’s noumenal theory. In doing this, I find reason to endorse a non-normative definition of power on the lines proposed by Robert Dahl and endorsed by most authors in analytical political theory. This definition nevertheless remains faithful to Forst’s methodological guideline that a theory of power must keep in view the relations between power and normativity. (shrink)
