The Guide laughed. "You are falling into their own error," he said, "the change is not radical, nor will it be permanent. That idea depends on a curious disease which they have all caught---an inability to dis-believe advertisements. To be sure, if the machines did what they promised, the change would be very deep indeed. Their next war, for example, would change the state of their country from disease to death. They are afraid of this themselves---though most of them are old enough to know by experience that a gun is no more likely than a toothpaste or a cosmetic to do the things its makers say it will do. It is the same with all their machines. Their labour-saving devices multiply drudgery; their aphrodisiacs make them impotent: their amusements bore them: their rapid production of food leaves half of them starving, and their devices for saving time have banished leisure from their country. There will be no radical change.
