Abstract：The relation between Marx and philosophy has always been one important concern of study.This paper begins with Marx's cognitive attitude toward alienation and points out the fact that Marx's real meaning of eliminating alienation is not to eradicate the concept itself, but its abstract usage. This view can be proved by the fact that alienation was retained on the theoretical and thinking level afterwards.Likewise, the real meaning of eliminating philosophy is to replace the old one with a new form of philosophy. Therefore, Marx's words that his philosophy was a positive science focused on differences between the old and new form of philosophy rather than stressing his theory was a pure science.
