Horkheimerian’s critique of the Enlightenment, shows the process whereby the demystification of the world is triggered by way of an “an act of sovereignty” of reason. There the man lost for reason his possibility of self-criticism, causing it to be in instrumental reason. Since its inception, the Enlightenment, as myth, mutilated reason, over the pursuit of truth –theoretical truth and moral truth–, there was a renounce to sense. The dream of Enlightenment rationality was reduced to the 'instrumentalization'. This dialectic not (...) only reveals the irreversible crisis of reason, but leaves in place, in the discussion of critical theory, the idea of the 'social pathology of reason', from which a “normative horizon” can be proposed, hinting at the scene of the ethical discussion the lack of rationality of societies.
