At the heart of the messianic thinking lies an unconditional idea of redemption. The messianic idea of unconditionality is based upon a qualitative distinction between the unredeemed world and the world to come. It is fundamental to this messianic idea that this distinction can't be grasped as transition or mediation. Taking his inspiration from thinkers like Jacques Derrida, Emmanuel Lévinas, Walter Benjamin and Franz Rosenzweig, Saitya Brata Das renews here this task of the unconditional, the task of thinking "the advent of pure future that is always to come", unenclosed in the bounds of law or in the cages of the "worldly". He thereby draws profound ethico-political implications from such a thought that opens up the infinitude of the future from the heart of our finitude, and shows that such thinking is the very task of our time.
