Abstract
This chapter discusses the philosophical side of Karl Marx's thought as well as some of the major debates about it in the secondary literature. It first examines Marx's early writings, focusing, in particular, on his views on religion, the limitations of political emancipation and the dehumanizing conditions of work under capitalism. Marx and Engels considered the theory of history to be one of Marx's most important theoretical achievements. In an autobiographical note Marx described it as the “guiding thread of his studies,” and in a speech delivered at Marx's graveside Engels compared Marx's discovery of “the law of development of human history” with Darwin's discovery of the law of nature. The chapter examines Marx's materialist theory of history, the view that history is characterized by the development of productive power to free people from material scarcity. It also examines the problematic area of Marx's ethics.
