In sixteenth-century Italy and eighteenth-century France, waning prosperity and increasing social unrest led the ruling families to try to preserve their superiority by withdrawing from the lower and middle classes behind barriers of etiquette. In a prosperous community, on the other hand, polite society soon absorbs the newly rich, and in England there has never been any shortage of books on etiquette for leaching them the manners appropriate to their new way of life. Every code of etiquette has contained three elements; basic moral duties; practical rules which promote efficiency; and artificial, optional graces such as formal compliments to, say, women on their beauty or superiors on their generosity and importance. In the first category are considerations for the weak and respect for age. Among the ancient Egyptians the young always stood in the presence of older people. Among the Mponguwe of Tanzania, the young men bow as they pass the huts of the elders. In England, until about a century ago, young children did not sit in their parents’ presence without asking permission. Practical rules arc helpful in such ordinary occurrences of social life as making proper introductions at parties or other functions so that people can be brought to know each other. Before the invention of the fork, etiquette directed that the fingers should be kept as clean as possible; before the handkerchief came into common use, etiquette suggested that after spitting, a person should rob the spit inconspicuously underfoot. Extremely refined behavior, however, cultivated as an art of gracious living, has been characteristic only of societies with wealth and leisure, which admitted Women as the social equals of men. After the fall of Rome, the first European society to regulate behavior in private life in accordance with a complicated code of etiquette was twelfth-century Provence, in France. Provence had become wealthy. The lords had returned to their castle from the crusades, and there the ideals of chivalry grew up, which emphasized the virtue and gentleness of women and demanded that a knight should profess a pure and dedicated love to a lady who would be his inspiration, and to whom he would dedicate his valiant deeds, though he would never come physically close to her. This was the introduction of the concept of romantic love, which was to influence literature for many hundreds of years and which still lives on in a debased form in simple popular songs and cheap novels today In Renaissance Italy too, in the fourteenth and fifteenth centuries, a wealthy and leisured society developed an extremely complex code of manners, but the rules of behavior of fashionable society had little influence on the daily life of the lower classes. Indeed many of the rules, such as how to enter a banquet room, or how to use a sword or handkerchief for ceremonial purposes, were irrelevant to the way of life of the average working man, who spent most of his life outdoors or in his own poor hut and most probably did trot have a handkerchief, certainly not a sword, to his name. Yet the essential basis of all good manners does not vary. Consideration for the old and weak and the avoidance of harming or giving unnecessary offence to others is a feature of all societies everywhere and at all levels from the highest to the lowest. According to the writer, part of chivalry is that ______.

David Landes, author of The Wealth and Poverty of Nations: Why Some Are So Rich and Some So Poor, credits the world’s economic and social progress over the last thousand years to "Western civilization and its dissemination." The reason, he believes, is that Europeans invented systematic economic development Landes adds that three unique aspects of European culture were crucial ingredients in Europe’s economic growth. First, science developed as an autonomous method of intellectual inquiry that successfully disengaged itself from the social constraints of organized religion and from the political constraints of centralized authority. Though Europe lacked a political center, its scholars benefited from the use of a single vehicle of communication: Latin. This common tongue facilitated an adversarial discourse in which new ideas about the physical world could be tested, demonstrated, and then accepted across the continent and eventually across the world. Second, Landes espouses a generalized form of Max Weber’s thesis that the values of work, initiative, and investment made the difference for Europe. Despite his emphasis on science, Landes does not stress the notion of rationality as such. In his view, "what counts is work, thrift, honesty, patience, [and] tenacity." The only route to economic success for individuals or states is working hard, spending less than you earn, and investing the rest in productive capacity. This is his fundamental explanation of the problem posed by his book’s subtitle: "Why Some Are So Rich and Some So Poor." For historical reasons—an emphasis on private property, an experience of political pluralism, a temperate climate, an urban style—Europeans have, on balance, followed those practices and therefore have prospered. Third, and perhaps most important, Europeans were learners. They "learned rather greedily," as Joel Mokyr put it in a review of Landes’s book. Even if Europeans possessed indigenous technologies that gave them an advantage (spectacles, for example), as Landes believes they did, their most vital asset was the ability to assimilate knowledge from around the world. and put it to use—as in borrowing the concept of zero and rediscovering Aristotle’s Logic from the Arabs and taking paper and gunpowder from the Chinese via the Muslim world. Landes argues that a systematic resistance to learning from other cultures had become the greatest handicap of the Chinese by the eighteenth century and remains the greatest handicap of Arab countries today. Although his analysis of European expansion is almost nonexistent, Landes does not argue that Europeans were beneficent bearers of civilization to a benighted world. Rather, he relies on his own commonsense law: "When one group is strong enough to push another around and stands to gain by it, it will do so." In contrast to the new school of world historians, Landes believes that specific cultural values enabled technological advances that in turn made some Europeans strong enough to dominate people in other parts of the world. Europeans therefore proceeded to do so with great viciousness and cruelty. By focusing on their victimization in this process, Landes holds, some postcolonial states have wasted energy that could have been put into productive work and investment. If one could sum up Landes’s advice to these states in one sentence, it might be "Stop whining and get to work." This is particularly important, indeed hopeful, advice, he would argue, because success is not permanent. Advantages are not fixed, gains from trade are unequal, and different societies react differently to market signals. Therefore, not only is there hope for undeveloped countries, but developed countries have little cause to be complacent, because the current situation "will press hard" on them. The thrust of studies like Landes’s is to identify those distinctive features of European civilization that lie behind Europe’s rise to power and the creation of modernity more generally. Other historians have placed a greater emphasis on such features as liberty, individualism, and Christianity. In a review essay, the art historian Craig Clunas listed some of the less well known linkages that have been proposed between Western culture and modernity, including the propensities to think quantitatively, enjoy pornography, and consume sugar. All such proposals assume the fundamental aptness of the question: What elements of European civilization led to European success It is a short leap from this assumption to outright triumphalism. The paradigmatic book of this school is, of course, The End of History and the Last Man, in which Francis Fuknyama argues that after the collapse of Nazism in the twentieth century, the only remaining model for human organization in the industrial and communications ages is a combination of market economics and limited, pluralist, democratic government. According to Landes, the main reason that some countries are so poor is that ______.
A throng of bearded men, in sad-colored garments and gray steeple-crowned hats, intermixed with women, some wearing hoods and others bareheaded, was assembled in front of a wooden edifice, the door of which was heavily timbered with oak and studded with iron spikes. The founders of a new colony, whatever Utopia of human virtue and happiness they might originally project, have invariably recognized it among their earliest practical necessities to allot a portion of the virgin soil as a cemetery, and another portion as the site of a prison. In accordance with this rule, it may safely be assumed that the forefathers of Boston had built the fast prison-house somewhere in the vicinity of Cornhill, almost as seasonably as they marked out the first burial-ground, on Isaac Johnson’s lot, and round about his grave, which subsequently became the nucleus of all the congregated sepulchres in the old churchyard of King’s Chapel. Certain it is that, some fifteen or twenty years after the settlement of the town, the wooden jail was already marked with weatherstains and other indications of age, which gave a yet darker aspect to its beetle-browed and gloomy front. The rust on the ponderous iron-work of its oaken door looked more antique than anything else in the New World. Like all that pertains to crime, it seemed, never to have known a youthful era. Before this ugly edifice, and between it and the wheel-track of the street, was a grassplot, much overgrown with burdock, pigweed, apple-peru, and such unsightly vegetation, winch evidently found something congenial in the soil that had so early borne the black flower of civilized society a prison. But on one side of the portal, and rooted almost at the threshold, was a wild rose-bush, covered, in this month of June, with its delicate gems, which might be imagined to offer their fragrance and fragile beauty to the prisoner as he went in, and to the condemned criminal as he came forth to his doom, in token that the deep heart of Nature could pity and be kind to him. This ruse-bush, by a strange chance, has been kept alive in history; but whether it had merely survived out of the stem old wilderness, so long after the fall of the gigantic pines and oaks that originally overshadowed it, or whether, as there is fair authority for believing, it had sprung up under the footsteps of the sainted Ann Hutchinson as she entered the prison-door, we shall not take upon us to determine. Finding it so directly on the threshold of our narrative, which is now about to issue from that inauspicious portal, we could hardly do otherwise than pluck one of its flowers and present it to the reader. It may serve, let us hope, to symbolize some sweet moral blossom that may be found along the track, or relieve the darkening close of a tale of human frailty and sorrow. The prison-house mentioned in the second paragraph must be ______.
