Willing and Understanding elucidates a variety of issues in and approaches to debating the will-intellect interplay in the late Middle Ages. Authored by prominent scholars in the field, the contributions offer different perspectives on the development of late medieval theories of the will. Charting a dense map of voluntarist and epistemological ideas—entrenched leitmotifs of late medieval philosophy, seminal insights sparking original trends, and ephemeral novelties—the volume is a testimony to the conceptual multidimensionality and ethical complexity of the past and present iterations of the debate on the will.
