The aim of this paper is to probe one of the philosophical resources (and/or of the alternatives) of contemporary messianic political philosophies (Giorgio Agamben, Alain Badiou, Slavoy Zizek etc.) in Jacques Derrida's reading of Walter Benjamin and Martin Heidegger. Derrida suggests the concept of 'the messianic without messianism' as a central category for a new emancipatory politics in the deconstructive readings of Benjamin's theory of violence and Heidegger's doctine of time in his Force of Law and Specters of Marx. I think it is necessary to understand the concept on the baisis of quasi-transcendentalism for appreciating its deep implications. On the quasi-transcendental reading of it, it becomes clear, I hope, that 'the messianic without messianism' could not only present a way to rethink the emancipatory politics beyond the worn-out dualisms (insurgency or reform, revolution or democracy etc.), but also open the philosophical perspective for a history(ies) of the transcendentals.
