 Among contemporary philosophers, Susan Wolf is one of several who address these worries. In her Freedom Within Reason Wolf argues that almost any morally problematic upbringing could be coercive and could render a person unable to see what he ought morally to do or render him unable to act on that recognition. As examples, Wolf cites ordinary citizens of Nazi Germany, white children of slave owners in the 1850s, and persons brought up to embrace conventional sex roles. Wolf thinks that there is no method for determining which upbringings and influences are consistent with an ability to see what should be done and to act accordingly, and hence she thinks there is always the risk that we are less responsible for our actions than we may hope.
