We have reached the point where the Objective Logic turns into the Subjective Logic, or, where subjectivity emerges as the true form of objectivity. … - Herbert Marcuse

The notion contradicts reality when the latter has become self-contradictory. Hegel says that a prevailing social form can be successfully attacked by thought only if this form has come into open contradiction with its own ‘truth,’ in other words, if it can no longer fulfill the demands of its own contents. P. 51

Marx explains the alienation of labor as exemplified in, first, the relation of the worker to the product of his labor and, second, the relation of the worker to his own activity. P. 276

Ascending modern rationalism, in its speculative as well as empirical form, shows a striking contrast between extreme critical radicalism in scientific and philosophic method on the one hand, and an uncritical quietism in the attitude toward established and functioning social institutions. Thus Descartes' ego cogitans was to leave the “great public bodies” untouched, and Hobbes held that “the present ought always to be preferred, maintained, and accounted best.” Kant agreed with Locke in justifying revolution if and when it has succeeded in organizing the whole and in preventing subversion. However, these accommodating concepts of Reason were always contradicted by the evident misery and injustice of the “great public bodies” and the effective, more or less conscious rebellion against them. Societal conditions existed which provoked and permitted real dissociation. from the established state of affairs; a private as well as political dimension was present in which dissociation could develop into effective opposition, testing its strength and the validity of its objectives. With the gradual closing of this dimension by the society, the self-limitation of thought assumes a larger significance. The interrelation between scientific-philosophical and societal processes, between theoretical and practical Reason, asserts itself "behind the back” of the scientists and philosophers. The society bars a whole type of oppositional operations and behavior; consequently, the concepts pertaining to them are rendered illusory or meaningless. Historical transcendence appears as metaphysical transcendence, not acceptable to science and scientific thought. The operational and behavioral point of view, practiced as a “habit of thought” at large, becomes the view of the established universe of discourse and action, needs and aspirations. The “cunning of Reason” works, as it so often did, in the interest of the powers that be. The insistence on operational and behavioral concepts turns against the efforts to free thought and behavior from the given reality and for the suppressed alternatives.
