Abstract
What should be called (at least according to the views supported by modern moral philosophy schools) the ‘modern moral world’ can be depicted nowadays as an environment in which we consider relations to the community to be morally significant, even when the individuals within the reach of these duties are in fact unknown. So we can blame or we can praise, even in the notorious absence of any identifiable subject of ‘moral obligation’. The fundamental difference is in perceived obligations, not in entitlements: duties versus rights. At first glance, moral entitlement is nothing but an abstract right seeking recognition. Not so the obligation, as the ‘right-bearer’ is waiting for the commitment to be honored. The work of Onora O’Neill, Charles Fried and Thomas M. Scanlon rounds out the argumentation of the normative frame that operates in today’s strongly supererogatory moral world.
