Abstract

The formal analysis of normative systems has traditionally focused on their deontic dimension rather than on their potestative dimension; yet, a growing amount of works aims at shedding light on the notion of power, its norm changing potential and its general interactions with deontic concepts. The present article contributes to this line of inquiry by adopting the following perspective: a normative system can be metaphorically seen as an agent that allocates abilities (powers) in order to promote the fulfillment of certain desires (deontic directives), and in doing so regulates its behavioural domain. Our analysis emphasizes the instrumental nature of power, while clarifying the distinction between ‘being allowed’ and ‘being enabled’ and unveiling new patterns of interaction between deontic and potestative concepts. Operationally, we formulate this framework in terms of conditional rules, and provide a corresponding logic programming (ASP) implementation.
