This excellent book focuses on a decisive moment in Schelling’s philosophical development [...] Berger and Whistler show how much the two philosophers learn from each other despite their fundamental disagreements, and one senses their friendship and mutual respect. This volume makes a significant contribution to our understanding of the development of German Idealism—but it also provides a model for dialogue and philosophical collaboration.
