Anxiety about the university job in Oxford "had contributed to Ludwig’s torment; he wanted that job so dreadfully. Of course, whatever happened now he would stay on in England after his London scholarship year was over. He had no more doubt about the rightness of his decision. The war was a piece of absolute wickedness in which he would take no part. He would not fight for the United States of America in that war. But neither was it his task to make politics, to shout and specify and martyr himself. I am not a political animal, he told himself repeatedly. He was a scholar. He would not waste his talents. He would stay in England, where by a pure and felicitous accident he had been born. To regret that his role was in so many ways an easy one was surely sentimental. The analysis was clear and the decision was made. Only his Protestant conscience, like a huge primitive clumsy processing machine, obsolete but still operational, continued to give him trouble. If only he could take that awful uncomprehending misery away from his parents. He dreaded their letters, in which they begged him to come home and get himself "straightened out". Old European terrors, inherited from generations of wandering ancestors, coursed in their blood and made them shudder from breaking the laws of the United States and evading its decrees. His father’s family was from Alsace. His mother’s were German. Ludwig’s parents had met soon after the war in France. They soon decided to emigrate to America, but while waiting for their visas went first on a brief visit to England so as to improve their English. Here young Ludwig had achieved an English birth, and with it the right to British nationality, although before his first birthday he was already in the U. S. A. He grew up happily enough, normally enough, as an American child, his parents’ joy. Yet in his blood, too, old European things lived and waited, and as he became an adult and an intellectual he found himself an unidentified person. His parents perfectly bi-lingual in French and German, spoke only English at home, laboriously conversing even when they were alone together, in this language which they never fully mastered. Ludwig learnt his French and German at school. When he came at last to Europe no blood relations awaited him. All had died or scattered. What mainly confronted him was the ghost of Hitler. This and many other things needed to be exercised. As a historian and as a man he needed somehow in thought to undergo the whole passion of recent history, but he could not do it. Faced with what he had so significantly missed, his intellect became hazy and faint. He remained outside it all and yet burdened by it as by something heavy forever trailing behind him, a part of himself that he could never properly see. In America he felt European, in France he felt German, in Germany American. Only in England, which he found in some ways most alien of all, could he somehow forget or postpone that problem of who he was. The company of other historians suited him, jokey unexcited men who just took him for granted and assumed quietly that of course he would stay and become British. He was so grateful for that. Meanwhile he knew that he did not feel guilty only because he was disappointing his parents. He felt guilty exactly as they did because he was disappointing the U. S. A. , because he was breaking the law, because he had decided not to return, because he feared death and would not be a soldier, because he was behaving as cowards and traitors behave. He accepted the guilt as a punishment for what was happening right now to his parents.

Passage 1 Imagine a world in which there was suddenly no emotion--a world in which human beings could feel no love or happiness, no terror or hate. Try to imagine the consequences of such a transformation. People might not be able to stay alive; knowing neither joy nor pleasure, neither anxiety nor fear, they would be as likely to repeat acts that hurt them as acts that were beneficial. They could not learn: they could not benefit from experience because this emotionless world would lack rewards and punishments. Society would soon disappear: people would be as likely to harm one another as to provide help and support. Human relationships would not exist: in a world without friends or enemies, there could be no marriage, affection among companions, or bonds among members of groups. Society’s economic underpinnings would be destroyed: since earning $10 million would be no more pleasant than earning $10, there would be no incentive to work. In fact, there would be no incentives of any kind. For as we will see, incentives imply a capacity to enjoy them. In such a world, the chances that the human species would survive are next to zero, because emotions are the basic instrument of our survival and adaptation. Emotions structure the world for us in important ways. As individuals, we categorize objects on the basis of our emotions. True, we consider the length, shape, size, or texture, but an object’s physical aspects are less important than what it has done or can do to us--hurt us, surprise us, anger us or make us joyful. We also use categorizations colored by emotions in our families, communities, and overall society. Out of our emotional experiences with objects and events comes a social feeling of agreement that certain things and actions are "good" and others are "bad", and we apply these categories to every aspect of our social life--from what foods we eat and what clothes we wear to how we keep promises and which people our group will accept. In fact, society exploits our emotional reactions and attitudes, such as loyalty, morality, pride shame, guilt, fear and greed, in order to maintain itself. It gives high rewards to individuals who perform important tasks such as surgery, makes heroes out of individuals for unusual or dangerous achievements such as flying fighter planes in a war, and uses the legal and penal system to make people afraid to engage in antisocial acts.
A. the capacity to compete for success B. the ability to work for pleasureC. the capacity to enjoy making money D. the ability to make money
