Bryan Lueck offers a substantially new solution to a classic philosophical problem: how is it possible that morality genuinely obligates us, binding us without regard to our perceived or actual well-being? 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. Building on Immanuel Kant's fact of reason--the idea that being a moral subject presupposes that one has accepted the bindingness of obligation--Lueck shows that moral obligation must be rethought as the fact of sense.
