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 BrechtI was called up in the war and sent to a hospital. I dressed wounds, applied iodine, gave enemas, did blood transfusions. If the doctor ordered: "Brecht, amputate a leg!", I would reply, "Certainly, Your Excellency!", and cut off the leg. If I was told, "Perform a trepanning!" I opened the man's skull and messed about with his brains. I saw how they patched fellows up, so as to cart them back to the Front as quickly as they could.
