The fact that wants can be synthesized by advertising, catalyzed by salesmanship, and shaped by the discreet manipulations of the persuaders shows that they are not very urgent. A man who is hungry need never be told of his need for food. If he is inspired by his appetite, he is immune to the influence of Messrs. Batten, Barton, Durstine & Osborn. The latter are effective only with those who are so far removed from physical want that they do not already know what they want. In this state alone, men are open to persuasion.
