The Edinburgh Critical History of Philosophy is a seven-volume reference work on the history of philosophy. This volume - which focuses on nineteenth-century philosophy - begins with the rise of German Idealism and Romanticism, and traces the developments of naturalism, positivism, and materialism, and of later-century attempts to combine idealist and naturalist modes of thought. Written by a team of leading international scholars, this crucial period of philosophy is examined from the novel perspective of themes and lines of thought which cut across authors, disciplines, and national boundaries. This fresh approach will open up new ways for specialists as well as students to conceptualise the history of nineteenth-century thought within philosophy, politics, religious studies and literature.
