In Homo Sacer, Giorgio Agamben makes the claim that Kant’s moral philosophy is prophetic of legal nihilism and modern totalitarianism. In doing so, he draws an implicit parallel between Kantian ethics of respect and autonomy, and the authoritarian constitutional theory of Carl Schmitt. This paper elucidates and evaluates this claim through an analysis of Agamben’s assertion that the legal condition of modernity is a nihilistic law that is ‘in force without significance’. I argue that the theoretical continuity between totalitarianism and (...) the Moral Law is the problem of the undecidable, which arises when the empty ground of normative judgment comes to light.
