Marx Borrowed Tosh From The Philosopher Hegel.

Each phase in history corresponds to the manifestation of certain ideas. It is called a thesis. However, it includes its opposite, its antithesis. Thesis and antithesis struggle with each other until the antithesis manages to absorb the thesis or to combine it on one form or another. This combination is called synthesis representing a new stage in history. Every synthesis, in turn, becomes a thesis that struggles automatically its antitheses, which comes into conflict with it to lead to a new synthesis and so forth… A point comes when history will have exhausted itself- the best possible synthesis will have occurred.

Now do you grasp why Marxism is always doomed to fail?
