Can we move beyond the religious-secular divide and live together ethically in a shared political world? Adorno and the Question of Theology: Religion and Reason Beyond Foundations says yes-and shows how. Through close readings of Dialectic of Enlightenment , Negative Dialectics , and Aesthetic Theory , Rachel R. Rosner examines how Adorno reconfigures the relationship between reason and theology to confront modern fragmentation. Drawing on Adorno's usage of constellation-a way of thinking that connects ideas without locking them into fixed systems-Rosner offers a way to move beyond entrenched dichotomies. In doing so, the book intervenes in contemporary debates on postsecular theory, critical reason, and political theology by rethinking how normativity and critique operate without foundations. Accessible to newcomers and illuminating for specialists, this book serves as both an introduction to Adorno's comprehensive philosophy and a path beyond enduring paradoxes in his reception.
