Feuerbach is now recognized as a central figure in the history of nineteenth-century thought. He was one of Hegel's most influential pupils: he dominated German radical philosophy in the 1840s and was the leader of the Young Hegelians; his 'anthropological' critique of Hegel's idealism decisively influences the materialism and humanism of Marx and Engels; his critique of religion pointed the way for the philosophers of religion; and his psychological analyses found a place in Freudian thought and the existential and phenomenological traditions. In this 1977 text, Professor Wartofsky wishes to go beyond this conventional view to establish Feuerbach as much more than a transitional figure between Hegel and Marx or an influence on important later developments. He seriously considers Feuerbach's philosophy on its own terms and seeks to demonstrate its continuing importance. He therefore traces Feuerbach's development in detail, emphasizing its dialectical character, and finds fundamental originality in his epistemology.
