Marxism of course adheres to the philosophy of dialectical materialism. Any such philosophy which does so, is inherantly flawed. Marxism fails to take into account the primacy of the individual over the collective. It fails to recognize that there are certain absolute truths, i.e.... it is wrong for the community to spurn the individual's god-given rights, and any society in which the individual is not protected from the whim of the community, is an immoral society. Yes, morality is a real true concept. Marxism fails to recognize this. Instead it turns to a false philosophy which locates what is real in material, and ignores the truth of virtue.
