单选题We assumed ethics needed the seal of certainty, else it was non-rational. And certainty was to be produced by a deductive model: the correct actions were derivable from classical first principles or a hierarchical ranked pantheon of principles. This model, though, is bankrupt. I suggest we think of ethics as analogous to language usage. There are no univocal rules of grammar and style which uniquely determine the best sentence for a particular situation. Nor is language usage universalizable. Although a sentence or phrase is warranted in one case, it does not mean it is automatically appropriate in like circumstances. Nonetheless, language usage is not subjective. This should not surprise us in the least. All intellectual pursuits are relativistic in just these senses. Political science, psychology, chemistry, and physics are not certain, but they are not subjective either. As I see it, ethical inquiry proceed like this: we are taught moral principles by parents, teachers, and society at large. As we grow older we become exposed to competing views. These may lead us to reevaluate presently held beliefs. Or we may find ourselves inexplicably making certain valuations, possibly because of inherited altruistic tendencies. We may "learn the hard way, that some actions generate unacceptable consequences. Or we may reflect upon our own and others' "theories" or patterns of behavior and decide they are inconsistent. The resulting views are "tested;" we act as we think we should and evaluate the consequences of those actions on ourselves and on others. We thereby correct our mistakes in light of the test of time. Of course people make different moral judgments; of course we cannot resolve these differences by using some algorithm which is itself beyond judgment. We have no vantage point outside human experience where we can judge right and wrong, good and bad. But then we don't have a vantage point from where we can be philosophical relativists either. We are left within the real world, trying to cope with ourselves, with each other, with the world, and with our own mistakes. We do not have all the moral answers; nor do we have an algorithm to discern those answers. Neither do we possess an algorithm for determining correct language usage but that does not make us throw up our hands in despair because we can no longer communicate. If we understand ethics in this way, we can see, I think, the real value of ethical theory. Some people talk as if ethical theories give us moral prescriptions. They think we should apply ethical principles as we would a poultice: after diagnosing the illness, we apply the appropriate dressing. But that is a mistake. No theory provides a set of abstract solutions to apply straightforwardly. Ethical theories are important not because they solve all moral dilemmas but because they help us notice salient features of moral problems and help us understand those problems in context.

单选题Eating better and more adventurously is becoming an obsession, especially among people with money to spend. Healthier eating-and not-so-healthy eating-as well as the number and variety of food choices and venues continue to increase at an ever quickening pace. Globalization is the master trend that will drive the world of food in the years ahead. Consumers traveling the globe, both virtually and in reality, will be able to sweep up ingredients, packaged foods, recipes, and cooking techniques from every comer of the earth at an ever-intensifying and accelerating pace. Formerly remote ingredients and cooking styles are creating a whole new culinary mosaic as they are transplanted and reinterpreted all over the world. Many factors are behind this, but none more so than the influence of the great international hotel chains. Virtually every chef who has worked for Hilton, Westin, Peninsula, or any other major chain gathers global experience in locales as diverse as Singapore, New Orleans, Toronto, and Dubai. At each stop, they carry away cooking ideas and techniques they can and do use elsewhere. This trend will gain even greater momentum as ambitious young adults stake their own futures on internationalization, treating broader food away as an important aspect of their own advancement. Young people will need knowledge of food and ingredients from different continents and cultures as one aspect of socialization, enculturation, cultural exchange, and success. In country after country, there seems little doubt that global cuisine will make its biggest inroads among the younger set. Many in the generations now coming of age will treat world-ranging food knowledge and experience as key elements in furthering their personal plans, business acumen, and individual growth. The Internet has made global contacts a matter of routine. Computer networking will permit chefs and others in the food industry, including consumers, to link directly with the best available authorities in faraway nations, supplementing or bypassing secondhand sources of information altogether. Time, with all its implications, will also be a factor in emerging world food trends. More and more of us are destined to operate on global time-that is, at full tilt 24 hours a day. This will become the norm for companies with resources scattered all over the planet. Beyond the 24-hour supermarkets many of us already take for granted, there will also be three-shift shopping centers open at any hour. Restaurants in the great business capitals intent on cultivating an international clientele will serve midnight breakfasts or break-of-dawn dinners (with the appropriate wines) without raising a single eyebrow.
