Passage adapted from G. C. Field's米oral Theory: an introduction(1921)

米oral Philosophy, as here conceived, is acriticismof our moral categories. We all know more or less what a moral judgment is, and we are all, of course, constantly making them. So-and-so is a good (or a bad) man, such-and-such an action is right (or wrong), are two types of the commonest forms of them. In such judgments, we use the ideas, or, to adopt our phraseology, the categories of good or bad, right or wrong. And in ordinary moral thinking we do not criticize these categories. Our interest then is centred in the question whether these or similar judgments are true or not. Is so-and-so a good man? Is this action right or wrong? We assume that there is something which we can call good or right, and we ask where it is present, what men or actions are good or right. But in Philosophy we shift our centre of interest. We are no longer concerned primarily with the question whether, for instance, any particular action is right or wrong; the question that we raise as moral philosophers is, “What does 'good' or 'right' mean?” That is, we are engaged in examining and criticizing our moral categories themselves, instead of, as in ordinary thinking, using and applying them in particular cases.

Passage adapted from James Seth,A Study of Ethical Principles(1898)

Ethics is the science of morality or conduct. It is accordingly often called practical, as opposed to theoretical, philosophy or metaphysics. The description is correct, if it is meant that ethics is the philosophy or theory of practice. It suggests, however, the question of the relations of moral theory and practice. Life or practice always precedes its theory or explanation; we are men before we are moralists. The moral life, though it implies an intellectual element from the first, is, in its beginnings, and for long, a matter of instinct, of tradition, of authority. The conceptions of good and evil, virtue and vice, duty and desert, which guide the life, not merely of the child but of the mass of mankind, are largely accepted, like intellectual notions, in blind and unquestioning faith. But moral, like intellectual, manhood implies emancipation from such a merely instinctive life; moral maturity brings with it reflection upon the meaning of life. The good man, like the wise man, puts away childish things; as a rational being, he must seek to reduce his life, like his world, to system. The contradictions and rivalries of ethical codes, the varying canons of moral criticism, the apparent chaos of moral practice, force upon him the need of a moral theory. This demand for a rationale of morality, for principles which shall give his life coherence, marks the transition from the practical to the theoretical standpoint, from life itself to its theoretic understanding.

The underlined word "criticism" in the first passage most closely means____________.

"The Passing of the Armies" by Joshua Lawrence Chamberlain (1915) Joshua Lawrence Chamberlain was a Brevet Major-General of U.S. Volunteers who was present at General Lee's surrender at Appomattox Courthouse in 1865. In the following paragraphs he describes a portion of one of the final battles of the Civil War.

The attack was impetuous; the musketry hot. Major Glenn with his six companies in skirmishing order dashed through the stream and struck the enemy's breastworks front and flank. In a moment everything started loose. The entire brigade forded the stream and rolled forward, closing upon Glenn right and left, and the whole command swept onward like a wave, carrying all before it a mile or more up the road, to the buildings of the Lewis Farm. The enemy now re-enforced made a decided stand, and the fight became sharp. But our enveloping line pressed them so severely that they fell back after each struggle to the edge of a thick wood, where a large body had gathered behind a substantial breastwork of logs and earth.

A withering volley breaks our line into groups. Courage and resolution are great, but some other sentiment mightier for the moment controls our men; a backward movement begins, but the men retire slowly, bearing their wounded with them, and even some of their dead. The enemy, seeing this recoil, pour out of their shelter and make a dash upon our broken groups, but only to be dashed back in turn hand to hand in eddying whirls. And seized by our desperate fellows, so many are dragged along as prisoners in the receding tide that it is not easy to tell which side is the winning one. Much of the enemy's aim is unsteady, for the flame and murk of their thickening fire in the heavy moist air are blown back into their eyes by the freshening south wind. But reinforcements are coming in, deepening and broadening their line beyond both our flanks. Now roar and tumult of motion for a fierce pulse of time, then again a quivering halt. At length one vigorous dash drives the assailants into the woods again with heavy loss. We had cleared the field, and thought it best to be content with that for the present. We reform our lines each side the buildings of the Lewis Farm, and take account of the situation.

Which of the following statements most accurately reflects the main idea of the passage?

"Europe and the Black Death"

In a series of lectures published after his death, historian David Herlihy theorizes that the Black Death led to the transformation of Western Europe and shaped crucial aspects of modern thinking and behavior. Herlihy’s lectures, written in 1985, draw comparisons to social phenomena associated with more recent epidemics, such as the influenza outbreak of 1919 and the mysterious arrival of AIDS in his own time. However, Herlihy writes that what made the Black Death so historically significant, other than the shocking death toll it levied, was the transformative impact that the plague had on labor markets, agrarian practices, economic innovation, and medical theory.

Herlihy’s lectures take aim at Thomas Malthus’s Iron Law of Population as laid out in his 1798 book titled An Essay on the Principle of Population. The Iron Law states that that population growth is necessarily limited by the available means of subsistence and actual population will be ultimately kept equal to the means of subsistence through catastrophic events. The Black Death, which deprived erstwhile-overpopulated 14th Century Europe of more than 25 million of its residents, became a seminal historical example of a Malthusian population check.

However, Herlihy cautions against characterizing the Black Death as a response to overpopulation in medieval Europe. If that were the case, he asserts, the epidemic would have arrived at the beginning of the century when population growth slowed amidst escalating food prices. Herlihy writes, "The medieval experience shows us not a Malthusian crisis but a stalemate, in the sense that the community was maintaining at stable levels very large numbers over a lengthy period." He posits that the term population deadlock, rather than population crisis, should be used to describe Europe before the epidemics.

According to Herlihy, the arrival of the Black Death to Europe in 1347 broke this deadlock. As a result of crashing populations, trade guilds and landowners went from a labor glut to a labor shortage virtually overnight. The shortage led to innovations in both agriculture and the production of goods. For example, Herlihy theorizes that the invention of the printing press in 1440 occurred in part because the Black Death and successive plagues culled the ranks of scribes needed to transcribe manuscripts by hand. He also argues that the sudden public health crisis bridged the divide between medical theorists and those actually treating patients, resulting in more anatomical research and medical innovation.

根据写道,更深刻的是代用的t the population crash had on longstanding medieval social structures. In addition to forcing agricultural innovation, the plague’s strengthening of the labor market reduced the peasant’s dependence on wealthy landowners. In fact, evidence shows that the labor ranks thinned even more during the outbreak from pessimistic workers who opted to spend their precious remaining time on earth in leisure. Those who continued to work enjoyed greater social mobility, which led to the passage of sumptuary laws by members of the elite desperate to maintain their caste superiority in a waning feudal economic system.

The primary purpose of the passage is to______________.
