The Preface to the Phenomenology is one of the greatest philosophical undertakings of all times, constituting no less an attempts than to reinstate p… - Herbert Marcuse

At the classical origins of philosophic thought, the transcending concepts remained committed to the prevailing separation between intellectual and manual labor to the established society of enslavement. … Those who bore the brunt of the untrue reality and who, therefore, seemed to be most in need of attaining its subversion were not the concern of philosophy. It abstracted from them and continued to abstract from them.

If dialectical logic understands contradiction as “necessity” belonging to the very “nature of thought,” … it does so because contradiction belongs to the very nature of the object of thought, to reality, where Reason is still Unreason, and the irrational still the rational. Conversely, all established reality militates against the logic of contradictions — it favors the modes of thought which sustain the established forms of life and the modes of behavior which reproduce and improve them. The given reality has its own logic and its own truth; the effort to comprehend them as such and to transcend them presupposes a different logic, a contradicting truth. They belong to modes of thought which are non-operational in their very structure; they are alien to scientific as well as common-sense operationalism. … These modes of thought appear to be a relic of the past, like all non-scientific and non-empirical philosophy. They recede before a more effective theory and practice of Reason.

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.
