Abstract
This paper will aim to propose a formal reconstruction of deontic evaluation over the externalized notion of agency through the indeterministic model of time (Thomason (1970)) with the primitive notion of choice. In the proposed model, an agent is defined as a series of choices, each of which is in turn formulated as a partition of the set of possibilities available at the moment. Options, or elements of a choice, are to be ordered by a preference relation that reflects the utility value of each possibility at the moment (cf. Horty (1995)). With the proposed model, the extended notion of agency with utilitarian decision making methods will cover the notions to be discussed in legal and social contexts in the age of organizations and communities with robots and artificial intelligence among human beings, such as group agency which may involve both natural persons and nonnatural (i.e. artificial) persons. The proposed choice-based model will also better describe transient agency, as groups can go through vicissitudes.
