As a philosopher, psychologist, and physician, the German thinker Hermann Lotze (1817–81) defies classification. Working in the mid-nineteenth-century era of programmatic realism, he critically reviewed and rearranged theories and concepts in books on pathology, physiology, medical psychology, anthropology, history, aesthetics, metaphysics, logic, and religion. Leading anatomists and physiologists reworked his hypotheses about the central and autonomic nervous systems. Dozens of fin-de-siècle philosophical contemporaries emulated him, yet often without acknowledgment, precisely because he had made conjecture and refutation into a method. In spite of Lotze's status as a pivotal figure in nineteenth-century intellectual thought, no complete treatment of his work exists, and certainly no effort to take account of the feminist secondary literature. Hermann Lotze: An Intellectual Biography is the first full-length historical study of Lotze's intellectual origins, scientific community, institutional context, and worldwide reception.

Frederick C. Beiser presents a study of the two most important idealist philosophers in Germany after Hegel: Adolf Trendelenburg and Rudolf Lotze. Trendelenburg and Lotze dominated philosophy in Germany in the second half of the nineteenth century. They were important influences on the generation after them, on Frege, Brentano, Dilthey, Kierkegaard, Cohen, Windelband and Rickert. Late German Idealism is the first book on this significant but neglected chapter in European philosophical history. It provides a general introduction to every aspect of the philosophy of Trendelenburg and Lotze—their logic, metaphysics, ethics and aesthetics—but it is also a study of their intellectual development, from their youth until their death. Their philosophy is placed in the context of their lives and culture.
