Staging a fruitful dialogue between the analytic and Continental philosophical traditions, while reflecting specifically on the work of Hegel, Merleau-Ponty, Serres and Nancy, Lueck offers a creative new approach to the problem of moral obligation. Lueck builds on Immanuel Kant's fact of reason - the idea that being a moral subject necessarily presupposes ones having accepted the bindingness of obligation - to show that it must be rethought as the fact of sense.
