The need to adapt to climate change brings about moral concerns that according to ‘eco-centric’ critiques cannot be resolved by modernist ethics, as this takes humans as the only beings capable of intentionality and rationality. However, if intentionality and rationality are reconsidered as ‘counterfactual hypotheses’ it becomes possible to align modernist ethics with the eco-centric approaches. These counterfactual hypotheses guide the development of institutions, so as to allow the pursuit of a ‘good life’. This mean that society should be organized as if humans are intentional and, following Habermas’s idea of ‘communicative rationality’, as if humans are capable of collective deliberation. Given the ecological challenges, the question becomes how to give ecological concerns a voice in deliberative processes.
