“Class consciousness is the ‘ethics’ of the proletariat, the unity of its theory and its practice, the point at which the economic necessity of its struggle for liberation changes dialectically into freedom.”

Lukacs, History and Class Consciousness

“Philosophy is theory of knowledge. Theory of knowledge is critique of language [Sprachkritik]. Critique of language, however, is labor on behalf of the liberating thought, that men can never succeed in getting beyond a metaphorical description [bildliche Darstellung] of the world utilizing either everyday language or philosophical language.”

Fritz Mauthner, Worterbuch der Philosophie
