This volume contains selections from the philosophical writings of James Frederick Ferrier (1808-1864). Ferrier was the Professor of Moral Philosophy at the University of St Andrews between 1845 and 1864 and he was one of the earliest post-Hegelian British idealists. He develops a system of absolute idealism via a rejection of the Scottish school of common sense and Enlightenment philosophy in general. These selections focus on his primary philosophical interests: epistemology and ontology. Ferrier denies the possibility of a science of man and suggests that philosophy should focus on self-consciousness, the defining feature of humanity. Jennifer Keefe is assistant professor of philosophy at the University of Wisconsin-Parkside.
