 Autonomy is the aspect of persons that undue paternalism offends against. Paternalistic interventions can be both interpersonal (governed by social and moral norms) and a matter of policy (mediated by formal or legal rules). Such interventions are identified not by the kind of acts they involve but by the justification given for them, so that paternalism involves interference with a person’s actions or knowledge against that person’s will for the purpose of advancing that person’s good. Respect for autonomy is meant to prohibit such interventions because they involve a judgment that the person is not able to decide for herself how best to pursue her own good. Autonomy is the ability to so decide, so for the autonomous subject of such interventions paternalism involves a lack of respect for autonomy. See also Paternalism.
