Ludwig Feuerbach and the End of Classical German Philosophy

Ludwig Feuerbach and the End of Classical German Philosophy  is a book published by Friedrich Engels in 1886. According to Engels, the seed for this book was planted 40 years before, in The German Ideology written by Marx and Engels, but unpublished in their lifetime. The undertaking is performed to deal critically with German philosophy from a dialectical materialist position. Here Engels emphasized the importance of Georg Wilhelm Friedrich Hegel and Ludwig Feuerbach for their own theories. Hegel's idealist, conservative system must be distinguished from his materialist, revolutionary method of dialectics. Feuerbach had turned to law against Hegel's idealistic system and "the fundamental question of philosophy": the relation of thinking and being. But Feuerbach rejected Hegel's dialectical method, which is why his view of man and nature remained abstract and unhistorical. Marx only kept the "rational" content from the dialectical method and freed it from their idealistic form.
