Social persons routinely tell themselves and others richly elaborated autobiographical stories filled with details about deeds, plans, roles, motivations, values, and character. Saul, let us imagine, is someone who once sailed the world as a young adventurer, going from port to port and living a gypsy existence. In telling his new acquaintance, Jess, of his former exotic life, he shines a light on his present character and this may guide to some extent their interaction here and now. Perhaps Jess also spent time at one of these port locations; perhaps their paths might even have crossed. They might be drawn into recounting some common events that indeed do establish a common link. Did they visit a certain famous landmark? Did they meet up at the same bars? And so on. When we open up to friends, acquaintances, colleagues, and close others through the stories we tell them, we do so by revealing bits of ourselves.

Effective agency, according to contemporary Kantians, requires a unity of purpose both at a time, in order that we may eliminate conflict among our motives, and over time, because many of the things we do form part of longer-term projects and make sense only in the light of these projects and life plans. Call this the unity of agency thesis. This thesis can be regarded as a normative constraint on accounts of personal identity and indeed on accounts of what it is to have the life of a person in the broad, rather than narrowly biological sense. It is also a fundamental condition of social life that persons within society fulfill a range of longitudinal roles: parenthood is one such obvious example, as are teachers, health professionals, engineers, artists, and many others. The fulfillment of these and other valuable social roles requires that agents have the capacity to rationally conceive of themselves as engaged in these roles and subject to the demands of them. To be unable to fulfill any such longitudinal social roles is to have a life deficient in value. The unity of agency is thus, we argue, something we rationally strive for, and something to be morally promoted. Psychiatric states that undermine the unity of agency are morally and rationally disvaluable. Using the example of dissociation, we explain how one such state may have this undermining or disruptive effect on the unity of agency. The therapeutic ends for psychiatry in conditions involving such states are thus seen more globally as the restoration of effective agency, that is, unified agency.

In this chapter I argue that there is a normative aspect to self-control that is not captured by the purely procedural account to be drawn from dual process theories of cognition – which we only uncover when we consider what self-control is for and why it is valuable. For at least a significant sub-group of addicts their loss of control over their drug use may not be due to a lack or depletion of cognitive resources. Rather it may be that they have little confidence in their ability to exert control over their circumstances and shape the life they would value having and the person they would value being.
