Abstract
In what sense could discourse ethics be linked with normative problems raised by the ecological crisis? Even if Apel and Habermas have not really addressed this question extensively, and even if their position in moral philosophy seems to develop and reinforce a neo-Kantian anthropocentric point of view, one can find in their works some evidence for the possibility of connecting a dialogical view with an ecological one. In order to defend the philosophical interest in highlighting this possibility, this essay analyses Habermas' position concerning the moral and ontological status of animality in particular, and attempts to situate this position within the history of Critical Theory.
