Habermas ante las objeciones de Hegel contra el deber ser kantiano: una concepción realista de lo ideal

Habermas shares with Kant the commitment to the posible, the ideal and duty to be moral, and with Hegel, the critique of the abstract carácter of kantian possibility and ought-be, as well as the realistic attention to the conditions of the really posible and the ideal. In this paper I intend to show that the confluence of such motifs, Kantian and Hegelian, in Habermas’ thought allows us to detect the keys to a conception of what should be and the ideal that does justice to the two essential features of what is really posible: the refence to the future and to conditions embedded in the real.
