General, your tank is a powerful vehicle It smashes down forests and crushes a hundred men. But it has one defect: It needs a driver. General, your bomber is powerful. It flies faster than a storm and carries more than an elephant. But it has one defect: It needs a mechanic. General, man is very useful. He can fly and he can kill. But he has one defect: He can think.
Bertolt BrechtA man who sees another man on the street corner with only a stump for an arm will be so shocked the first time he'll give him sixpence. But the second time it'll only be a three penny bit. And if he sees him a third time, he'll have him cold-bloodedly handed over to the police.
Bertolt Brecht
