It is difficult to overstate the importance of the task undertaken by Moyn and Schine in this book. For the first time ever, key chapters in Ethik des reinen Willens are available in English. This volume also collects and translates major essays by Ernst Cassirer, Franz Rosenzweig, and Alexander Altmann that have done so much to shape Cohen’s reception in the twentieth and twenty-first centuries. With expert introductions and annotations, this book will be a landmark event in discussions of Cohen in the English-speaking world.
