While traditional moralities are based on the primacy of autonomy, the ethics of care, that is more concrete and more contextualist, emphasizes the notion of vulnerability as it considers an essential feature of the human condition. This ethical issue of feminist thought today tends to free itself from its origins and spread to the political sphere. Not necessarily oppose the value of autonomy and justice considered a universalist point of view, it defines the conditions for their effectiveness. Autonomy can not be regarded as a principle but as a horizon. As for justice, it takes a real meaning only if it is the result of concern for others and oneself as vulnerable.
