Only a very soft-headed, sentimental, and rather servile generation of men could possibly be affected by advertisements at all. People who are a little more hard-headed, humorous, and intellectually independent, see the rather simple joke; and are not impressed by this or any other form of self-praise. Almost any other men in almost any other age would have seen the joke. If you had said to a man in the Stone Age, ‘Ugg says Ugg makes the best stone hatchets,’ he would have perceived a lack of detachment and disinterestedness about the testimonial. If you had said to a medieval peasant, ‘Robert the Bowyer proclaims, with three blasts of a horn, that he makes good bows,’ the peasant would have said, ‘Well, of course he does,’ and thought about something more important. It is only among people whose minds have been weakened by a sort of mesmerism that so transparent a trick as that of advertisement could ever have been tried at all.
