An insult offends a person’s dignity if it consists of or implies a denial that he is an autonomous person or that he deserves to be treated as one. An action enslaves another if it practically denies him all options through the manipulation of the environment….One manipulates a person by intentionally changing his tastes, his beliefs or his ability to act or decide. Manipulation—in other words—is manipulation of the person, of those factors relevant to his autonomy which are internal to him. Enslavement is the elimination of control by changing factors external to the person. (p.221)
