In the human reality, all existence that spends itself in procuring the prerequisites of existence is thus an "untrue” and unfree existence. Obviously this reflects the not at all ontological condition of a society based on the proposition that freedom is incompatible with the activity of procuring the necessities of life, that this activity is the "natural” function of a specific class, and that cognition of the truth and true existence imply freedom from the entire dimension of such activity. ... Society still is organized in such a way that procuring the necessities of life constitutes the full-time and life-long occupation of specific social classes, which are therefore unfree and prevented from a human existence. In this sense, the classical proposition according to which truth is incompatible with enslavement by socially necessary labor is still valid.
