Abstract
From the perspective of Marek J. Siemek’s theory of modernity, one of the most important problem is to include conflicts into institutional framework of the modern society. He reinterprets Hegel’s dialectics of the struggle for recognition by conceptual tools of Hobbes and Marx in order to uncover hidden assumptions and conditions of possibility of the social rationality. For Siemek, law as purely formal, autopoetic social system or social subject, which produces individual subjects, is the first of the conditions of possibility of modernity. The second one is the convergence of formal and material presuppositions of law—or, speaking generally—the convergence of form and content of the social reason. Form and content, facticity and normativity, instrumentality and communicativity are aspects of the process of rationalization andof the only one reason, self-generating in the history. So for Siemek, the Hegelian model of the struggle for recognition gains its theoretical power only when it is interpreted from the perspective of economical, technical and legal rationalization of modernity. Only such perspective is able to construct “the transcendental social philosophy” which starts from critique of “the non-instrumental reason”.
