It is the sphere farthest removed from the concreteness of society which may show most clearly the extent of the conquest of thought by society. - Herbert Marcuse

Man alone has the power of self-realization, the power to be a self-determining subject in all processes of becoming, for he alone has an understanding of potentialities and a knowledge of ‘notions.’ His very existence is the process of actualizing his potentialities, of molding his life according to the notions of reason. P. 9

The category “society” itself expressed the acute conflict between the social and political sphere—society as antagonistic to the state. Similarly, “individual,” “class,” “private,” “family” denoted spheres and forces not yet integrated with the established conditions—spheres of tension and contradiction. With the growing integration of industrial society, these categories are losing their critical connotation, and tend to become descriptive, deceptive, or operational terms. An attempt to recapture the critical intent of these categories, and to understand how the intent was cancelled by the social reality, appears from the outset to be regression from a theory joined with historical practice to abstract, speculative thought: from the critique of political economy to philosophy. This ideological character of the critique results from the fact that the analysis is forced to proceed from a position “outside” the positive as well as negative, the productive as well as destructive tendencies in society.

Such abstraction which refuses to accept the given universe of facts as the final context of validation, such “transcending” analysis of the facts in the light of their arrested and denied possibilities, pertains to the very structure of social theory.
