Karl MarxLabor in the white skin can never free itself as long as labor in the black skin is branded.
Karl MarxWe know only a single science, the science of history. History can be contemplated from two sides, it can be divided into the history of nature and the history of mankind. However, the two sides are not to be divided off; as long as men exist the history of nature and the history of men are mutually conditioned.
Karl Marx
