Frederick C. Beiser presents the first book to be written on two of the most important idealist philosophers in Germany after Hegel: Adolf Trendelenburg and Rudolf Lotze. Beiser addresses every aspect of their philosophy-- logic, metaphysics, ethics, and aesthetics--and traces their intellectual development from their youth until their death. Beiser expounds Trendelenburg's and Lotze's philosophy with impeccable scholarship, immense learning and judicious philosophical commentary.
