 As we have seen, with respect to children the argument is straightforward: it is difficult to see how one could acquire moral responsibility, and eventually become fully autonomous, without close and ongoing relationships with moral mentors. As Virginia Held argues, it is the work of parents to create persons (Held 1993). But adults, too, have been said to require enough decent human constant in order to maintain their autonomy: if social deprivation is likely to seriously erode mental health, then it will eventually also undermine autonomy (Brownlee 2013). One illustration, often discussed by Brownlee (2013, forthcoming), is that of prisoners held in isolation who sometimes end up preferring brutal interaction with interrogators to continued forced solitude. Even less than minimally decent relationships seem desirable compared to the mental suffering, and eventual psychological disintegration provoked by complete social isolation.
