The series Rethinking Kant, now in its fourth volume, has become a mirror of Kantian studies in North America. It gathers papers presented at the various study groups of the North American Kant Society, along with contributions from hosts, session chairs, and keynote speakers. Contributions undergo strenuous peer review, and are, without exception, examples of the most innovative and cutting-edge research done in this area. Anyone interested in taking the pulse of contemporary Kantian scholarship and engaging in the humbling, but rewarding task of rethinking Kant, should consider this collection.
