Principles of Marxist philosophy – 
Marxism is an economic and social system based upon the political and economic theories of Karl Marx and Friedrich Engels. While it would take veritably volumes to explain the full implications and ramifications of the Marxist social and economic ideology, Marxism is summed up in the Encarta Reference Library as “a theory in which class struggle is a central element in the analysis of social change in Western societies.” Marxism is the antithesis of capitalism which is defined by Encarta as “an economic system based on the private ownership of the means of production and distribution of goods, characterized by a free competitive market and motivation by profit.” Marxism is the system of socialism of which the dominant feature is public ownership of the means of production, distribution, and exchange.
