Agency as internal control
This chapter provides an overview of field theory and the notion of agency that the theory entails. Field theory offers an account of how goal-directed systems work by noting how goal-directed entities are guided by upper-level fields that are structured hierarchically. Following field theory, we show that while all agential entities are goal-directed, the presence of goal directedness does not necessarily entail agency. Rather, agency comes about when a goal-directed entity has the right kind of internal, hierarchical organization, and as a result of that organization, the entity has some degree of control over its internal processes and gross behavior. In this view, control is independent of determinism. An entity that is completely determined, whether by external or internal processes, can nevertheless be agential. This view of agency has several unintuitive consequences. In particular, it shows that an entity can be maximally agential when it lacks all external guidance, even when it moves randomly or behaves maladaptively. Agency means doing what you want, not what you should.
