This paper revisits the Kantian concept of law, observing principally its moral groundwork and then brings to the discussion the Habermas’ concept of law, culminating in some appreciations on the content and validity of the critique of Habermas to Kant, namely, the hypothesis of a dilution of Kantian law in the moral. For Habermas, the law is an autonomous sphere and should not be based on moral a priori, but must perforce draw support in the ethics of discourse and in (...) consensus. (shrink)
