The philosopher … subjects experience to his critical judgment, and this contains a value judgment — namely, that freedom from toil is preferable to … - Herbert Marcuse

Hegel’s philosophy revolved about the universality of reason; it was a rational system with its every part (the subjective as well as the objective spheres) integrated into a comprehensive whole. Marx shows that capitalist society first put such a universality into practice. P. 286-287

In the Platonic dialectic, … the terms “Being” “Non-being” “Movement,” “the One and the Many” “Identity” and “Contradiction” are methodically kept open, ambiguous, not fully defined. They have an open horizon, an entire universe of meaning which is gradually structured in the process of communication itself, but which is never closed. The propositions are submitted, developed, and tested in a dialogue, in which the partner is led to question the normally unquestioned universe of experience and speech, and to enter a new dimension of discourse — otherwise he is free and the discourse is addressed to his freedom. He is supposed to go beyond that which is given to him — as the speaker, in his proposition, goes beyond the initial setting of the terms. These terms have many meanings because the conditions to which they refer have many sides, implications, and effects which cannot be insulated and stabilized.

We return to our analysis of qualities. Something preserves itself throughout this flux, something that passes into other things, but also stands against them as a being for itself. This something can exist only as the product of a process through which it integrates its otherness with its own proper being. Hegel says that its existence comes about through ‘the negation of the negation.’ The first negation is the otherness in which it turns, and the second is the incorporation of this other into its own self. Such a process presupposes that things possess a certain power over their movement, that they exist in a certain self-relation that enables them to ‘mediate’ their existential conditions. P. 132-133
