In the issue of"the Relationship between Historical Materialism and Political Philosophy",scholars have always had two views of compatibility and incompatibility.While it has become a consensus that Political Philosophy is a normative theory,Historical Materialism in what sense is"die wirkliche,positive Wissenschaft"has become the key to resolving the disagreement.Back to young Marx's critique of the positivism of contemporary thinkers,"die wirkliche,positive Wissenschaft"is based on experience but not confined to experience,always maintains the ability to criticize and transcend the existing,and constantly goes from theory to practice.As"die wirkliche,positive Wissenschaft"has both factual and value dimensions,Historical Materialism and Political Philosophy are compatible with each other.
