Two theme–setting quotations introduce this essay—that of Yeats's falcon, deaf to the falconer's call, adrift in space above the blood–dimmed tide, counterpoised to Pierre Teilhard de Chardin's call to abandon old nationalistic prejudices and build the earth. With primary references to the thought of Teilhard, along with, among others, to Ewert Cousins, Andrew M. Greeley, Karl Jaspers, Marshall McLuhan, Ilya Prigogine, Karl Rahner, Leonard Swidler, David Tracy, and Alfred North Whitehead, I argue that the most crucial intellectual paradigm shift of the twenty–first century will challenge humanity to take the turn from uncritical attachment to rigid absolutism or atomistic fragmentation toward a sense of open–ended, off–centered centeredness and fluid connections—from a static to a dynamic model of reality. Central to my argument is the Teilhardian reinterpretation of the Christian metaphors of creation, fall, incarnation, salvation, and the eschaton in the evolutionary terms of the emergence of cosmic consciousness from the chrysalis of the world of the past—from chaos to order, from biosphere via noosphere to theosphere. Facilitated by the exponential growth of populations, collaborative research, science, technology, and global communication (most dramatically manifested by the Internet), this emergent understanding of what it means to be human can, first, foster the awareness that in humanity evolution has become conscious of itself, and then, gradually, precipitate the formation of “the global village” (the mystical body of Christ), as respectful dialogue replaces diatribe and the dualistic pugilism of Samuel Huntington's “Clash of Civilizations” is gradually transformed into a nonadversarial mentality that values shared humanity and a common purpose. Thus, eons hence, empowered by love–energy, the transmutation of the human into the ultra–human can take the ultimate quantum leap into a yet higher dimension where spirit/energy is no longer in need of flesh/mass, and Earth can be safely left behind. 相似文献

This article explores the structure of world order fromthe perspective of the Treaty of Westphalia, which is treated asthe benchmark for the emergence of the modern system of sovereignstates. Emphasis is placed on Westphalia as historical event, ideaand ideal, and process of evolution, and also on developments thatsupersede this framing of world politics, especially, globalizationand the megaterrorist challenge of September 11, 2001. At issue is whether the state system is resilient enough to adapt to new globalconditions or is in the process of being supplanted, and whether thesequel to Westphalia is moving toward humane global governance orsome dysutopic variant, or both at once. 相似文献

中学生知识获得过程是从情景记忆向语义记忆转化的过程 总被引:2,自引:0,他引:2
本研究探讨中学生的知识掌握过程。针对2001—2002年度上学期教学内容,对初中二年级学生的四门课程分别进行两次测验。对于每道选择题,学生首先选择正确答案,然后指出记忆的意识状态:记住的、知道的、猜测的。结果发现,学生记忆意识类型的转变(由记住向知道)取决于课程类型、保持时间和学生等级。对于不同课程,学生占优势的意识类型不同,自然学科知道的反应占优势,社会学科记住的反应占优势;优等生知道的反应多于其他学生;随着学习时间的延长,中学生的意识类型发生了由记住向知道的转变,这表明知识掌握过程中,中学生的知识表征发生了由情景记忆向语义记忆的转变。 相似文献

Alternative views of the nature of consciousness posit that awareness of an object is either an all-or-none phenomenon or that awareness can be partial, occurring independently for different levels of representation. The all-or-none hypothesis predicts that when one feature of an object is identified, all other features should be consciously accessible. The partial awareness hypothesis predicts that one feature may reach consciousness while others do not. These competing predictions were tested in two experiments that presented two targets within a central stream of letters. We used the attentional blink evoked by the first target to assess consciousness for two different features of the second target. The results provide evidence that there can be a severe impairment in conscious access to one feature even when another feature is accurately reported. This behavioral evidence supports the partial awareness hypothesis, showing that consciousness of different features of the same object can be dissociated. 相似文献

The primary purpose of government is to secure public goods that cannot be achieved by free markets. The Coordination Principle tells us to consolidate sovereign power in a single institution to overcome collective action problems that otherwise prevent secure provision of the relevant public goods. There are several public goods that require such coordination at the global level, chief among them being basic human rights. The claim that human rights require global coordination is supported in three main steps. First, I consider Pogge's and Habermas's analyses as alternatives to Hobbesian conceptions of justice. Second, I consider the core conventions of international law, which are in tension with the primacy of state sovereignty in the UN system. Third, I argue that the just war tradition does not limit just causes for war to self‐defense; it supports saving innocent third parties from crimes against humanity as a just reason for war. While classical authors focused less on this issue, the point is especially clear in twentieth‐century just war theories, such as those offered by the American Catholic bishops, Jean Elshtain, Brian Orend, and Michael Walzer. Against Walzer, I argue that we add intractable military tyranny to the list of horrors meriting intervention if other ad bellum conditions are met. But these results require us to reexamine the “just authority” of first resort to govern such interventions. The Coordination Principle implies that we should create a transnational federation with consolidated powers in place of a treaty organization requiring near‐unanimity. But to be legitimate, such a global institution must also be directly answerable to the citizens of its member states. While the UN Security Council is inadequate on both counts, a federation of democracies with a directly elected executive and legislature could meet both conditions. 相似文献

Even when people perform tasks poorly, they often report unrealistically positive estimates of their own abilities in these situations. To better understand the origins of such overconfidence, we investigated whether it could be predicted by individual differences in working memory, attentional control, and self-reported trait impulsivity. Overconfidence was estimated by contrasting objective and subjective measures of situation awareness (the ability to perceive and understand task-relevant information in the environment), acquired during a challenging air traffic control simulation. We found no significant relationships between overconfidence and either working memory or attentional control. However, increased impulsivity significantly predicted greater overconfidence. In addition, overall levels of overconfidence were lower in our complex task than in previous studies that used less-complex lab-based tasks. Our results suggest that overconfidence may not be linked to high-level cognitive abilities, but that dynamic tasks with frequent opportunities for performance feedback may reduce misconceptions about personal performance. 相似文献
