“Learning to be Human” is the theme of the 24th World Congress of Philosophy, to be held in Beijing in 2018, and also an important topic in traditional Chinese Confucian philosophy. Different interpretations of this theme, however, directly determine how to understand the study of Chinese philosophy in the context of world philosophy today. Changes in contemporary philosophy urge us to reconsider philosophical research in today’s China. Reflecting on the status quo of research on Chinese philosophy and finding a method for solving certain existing difficulties will ultimately enhance the study of Chinese philosophy. 相似文献

采用中学生、大学生焦虑敏感问卷和匹兹堡睡眠质量指数量表(PSQI),分别对1011名中学生和607名大学生进行调查。结果显示高焦虑敏感学生的PSQI总分显著高于低焦虑敏感学生,焦虑敏感及其三个因子与PSQI的相关都是中效应,焦虑敏感对青少年学生睡眠质量指数具有显著的正向预测作用,焦虑敏感水平越高,其睡眠质量越差。焦虑敏感可能以应激事件和健康问题作为致敏源,以焦虑等负性情绪作为敏感内容,在消极自动认知觉察与思维的介入下,进一步放大对有关负性情绪的感受与体验,从而影响青少年学生的睡眠质量。 相似文献

Within the domain of metacognition, there is disagreement whether different processes underlie evaluations of confidence in perceptual versus conceptual decisions. The relationship between confidence and accuracy for perceptual and conceptual decisions was compared using newly created stimuli that could be used to elicit either decision type. Based on theories of Brunswikian and Thurstonian uncertainties, significant underconfidence for perceptual decisions and overconfidence for conceptual decisions were predicted. Three within‐subjects experiments did not support this hypothesis. Participants showed significant overconfidence for perceptual decisions and no overconfidence for conceptual decisions. In addition, significant hard‐easy effects were consistently found for both decision types. Incorporating our findings with past results reveals that both over‐ and underconfidence are attainable on perceptual tasks. This conclusion, in addition to the common presence of hard‐easy effects and significant across‐task correlations in over/underconfidence, suggests that confidence judgments for the two decision types may depend on largely shared processes. Possible contributions to confidence and over/underconfidence are explored, focusing on response time factors and participants' knowledge bases. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

The paper tries to provide an alternative to Hempel’s approach to scientific laws and scientific explanation as given in his
D-N model. It starts with a brief exposition of the main characteristics of Hempel’s approach to deductive explanations based
on universal scientific laws and analyzes the problems and paradoxes inherent in this approach. By way of solution, it analyzes
the scientific laws and explanations in classical mechanics and then reconstructs the corresponding models of explanation,
as well as the types of scientific laws appearing in it. Finally, it compares this reconstruction with the approaches of J.
Woodward and C. Hitchcock, C. Liu and with the views of M. Thalos on analytic mechanics.

The study focused on the cognitive determinants of the accuracy of feeling-of-knowing (FOK) judgments made on episodic memory information. An individual differences approach was used on a sample of healthy older adults assessed on an episodic FOK task and on several neuropsychological measures. At a global level of analysis of FOK accuracy, the contributions of four general cognitive processes--episodic memory, executive functioning, fluid intelligence and processing speed--were examined concurrently. Stepwise regression analyses showed that executive functioning accounted for the major part of variance on FOK accuracy, followed by a significant contribution of episodic memory. After controlling for executive and memory involvement, fluid intelligence and processing speed no longer accounted for significant variance. At a more detailed level of analysis of FOK accuracy, the contributions of three specific executive processes--shifting, updating and inhibition--were assessed. The results revealed shifting function as the primary executive process engaged in the production of accurate FOK judgments in episodic memory. Some hypotheses are put forward to better understand the central role of executive functioning in the production of accurate FOK judgments. 相似文献

Spies, like soldiers, do a job and employ tactics that need justifying. I offer an argument for how Christian ethics may handle the moral problems of spying and do so by looking at the morally troubling tactics used by spies through the eyes of those who played an important role in shaping Christian theology and philosophy and have become normative in Christian moral thinking on the use of force. I argue that spying may be justifiable when we conceive the profession as a kind of use of force that is governed by the just war criteria. Spying is a particular kind of use of force that takes its moral character from those who authorize it, with what justification, to what ends, and with what methods. Particular attention is given to the tactics of disregarding the rules of war, the telling and living of lies, running covert operations, and assassinating military and political leaders. 相似文献

Six “divine conjectures” frame the place of Theóne (The One to Whom we pray) in the creation of our universe and for its continuing development in five subsequent stages into a loving universe. The first stage, the cosmological universe, establishes the laws of nature, understood by scientists as the “standard model”. The second stage introduces life and death into the universe by a process we are only now beginning to understand. Stage 3 requires certain life forms to become conscious with a subset of those life‐forms acquiring language that results in that subset becoming self‐conscious. The next stage, Conjecture 4, identifies certain persons who become addicted to learning in their unrelenting effort to learn as much of what can be known as possible. The fifth conjecture requires individual persons to act as agents of Theóne in achieving Conjecture 6—a universe that is both loving and lawful. During the course of the exposition subsidiary discussions of the concepts of conjecture and hypothesis explicate the function of each in the advancement of knowledge and understanding. There are brief discussions of prayer and purpose in relation to the Divine. 相似文献

Sydney Shoemaker leads today’s “neo-Lockean” liberation of persons from the conservative animalist charge of “neo-Aristotelians”
such as Eric Olson, according to whom persons are biological entities and who challenge all neo-Lockean views on grounds that
abstracting from strictly physical, or bodily, criteria plays fast and loose with our identities. There is a fundamental mistake
on both sides: a false dichotomy between bodily continuity versus psychological continuity theories of personal identity.
Neo-Lockeans, like everyone else today who relies on Locke’s analysis of personal identity, including Derek Parfit, have either
completely distorted or not understood Locke’s actual view. Shoemaker’s defense, which uses a “package deal” definition that
relies on internal relations of synchronic and diachronic unity and employs the Ramsey–Lewis account to define personal identity,
leaves far less room for psychological continuity views than for my own view, which, independently of its radical implications,
is that (a) consciousness makes personal identity, and (b) in consciousness alone personal identity consists—which happens to be also Locke’s actual view. Moreover, the ubiquitous Fregean conception of borders and the so-called “ambiguity
of is” collapse in the light of what Hintikka has called the “Frege trichotomy.” The Ramsey–Lewis account, due to the problematic
way Shoemaker tries to bind the variables, makes it impossible for the neo-Lockean ala Shoemaker to fulfill the uniqueness
clause required by all such Lewis style definitions; such attempts avoid circularity only at the expense of mistaking isomorphism
with identity. Contrary to what virtually all philosophers writing on the topic assume, fission does not destroy personal
identity. A proper analysis of public versus perspectival identification, derived using actual case studies from neuropsychiatry,
provides the scientific, mathematical and logical frameworks for a new theory of self-reference, wherein “consciousness,”
“self-consciousness,” and the “I,” can be precisely defined in terms of the subject and the subject-in-itself. 相似文献

Three kinds of rhymes: An ERP study 总被引:1,自引:0,他引:1
In a simple prime-target visual rhyming paradigm, pairs of words, nonwords, and single letters elicited similar event-related potential (ERP) rhyming effects in young adults. Within each condition, primes elicited contingent negative variation (CNV) while nonrhyming targets elicited more negative waveforms than rhyming targets within the 320-500ms (N400/N450) time window. The target rhyming effect, apparently primarily an index of phonological processing, was similar across conditions but tended to be smaller in mean amplitude for letters. One of the first reports of such a letter rhyming effect in the ERP literature, these findings could be important developmentally because letter rhyme tasks simultaneously index the two best predictors of ease of learning to read: letter name knowledge and phonological awareness. 相似文献
