Abstract: With The German Ideology as the boundary,Marxs use and view of “consciousness” is from regarding it as an object with “philosophical specific meaning” which “needs to be understood and recognized” to interpreting it as an “independent” concept corresponding to “real life”.“Consciousness” is the reflection of the existence of human society.Before it is transformed into “ideology”,it must be embodied into “idea” and evolve into ideology in two modes.One has become a “form of consciousness” representing the superstructure,that is,a broad and neutral ideology;the other has been transformed into an ideology with negative implications,which is due to the alienated labor,class construction and other factors,which have produced negative implications in the process of concreting into ideas.

Key words: consciousness, idea, forms of social consciousness, ideology
