Debates about the unique, the singular, and the individual raise epistemological, hermeneutical, metaphysical, ethical, and theological problems. They are often discussed in separate discourses without attention to the multiple relationships that exist among these issues. This volume seeks to remedy this by linking three areas of discussion: the theological and metaphysical debates about divine uniqueness, the epistemological and hermeneutical debates about issues of singularity and (in)comparability, and the ethical debates about issues of human individuality and ethical formation. Taken together, this highlights the complex background of the current singularity debate and shows that it is worth paying attention to debates in other fields where similar questions are explored in a different way.
