Abstract: Since the Enlightenment, with the loss of traditional moral authority and the rise of human subjective rationality, the contradiction between fact and value has prepared the way for moral relativism. As a theory that reveals the laws of human social development, historical materialism is based on the criticism of various “eternal truths”, and provides support for the diversity and rheology of morality. However, this is often considered to lead to moral relativism, which in turn negates the theoretical legitimacy of the proletariat's moral critique of capitalism. In fact, although historical materialism conforms to some of the characteristics of descriptive relativism, it does not accept restrictive proposition and thus does not lead to metaethical or normative moral relativism. On the contrary, historical materialism can explain the objective law of moral change by establishing moral objectivity on the basis of productive forces and modes of production, and support to interpret moral objectivism in the way of the idea of moral progress.

Key words:  historical materialism, moral objectivity, moral relativism
