Roger Crisp believes that all forms of “persuasive" advertising are morally wrong. What does he mean by “persuasive" advertising, and what, in general, does he see unethical about it? In what way does this kind of advertising destroy the “autonomy” of the buyer which he believes must be respected for ethical marketing? Another author, Robert Arrington disagreed with Crisp's analysis, and in 1982 published a critique of Crisp titled, Advertising and Behaviour Control (not published in our text but mentioned in Crisp's article) in which he argues that the techniques of "persuasive" advertising do not override the four essential notions regarding the personal autonomy of consumers: autonomous desire, rational desire and choice, free choice, control and manipulation. In the remainder Crisp's article in our text, he considers these challenges of Arrington but still defends his original opinion about the immorality of "persuasive" advertisng. Breifly summarize the four challenges of Arrington and Crisp's.
