In this paper, it is argued that metaphysics, conceived as an inquiry into the ultimate nature of mind-independent reality, is a rationally indispensable intellectual discipline, with the a priori science of formal ontology at its heart. It is maintained that formal ontology, properly understood, is not a mere exercise in conceptual analysis, because its primary objective is a normative one, being nothing less than the attempt to grasp adequately the essences of things, both actual and possible, with a view to understanding as far as we can the fundamental structure of reality as a whole. Accordingly, it is urged, the deliverances of formal ontology have a modal and epistemic status akin to those of other a priori sciences, such as mathematics and logic, rather than constituting rivals to the claims of the empirical sciences, such as physics.  相似文献

The decision to get married, as well as choosing whom to marry, is of the utmost importance to most people. This decision consists of many amoral considerations, but an ethical relationship arises when a promise is made, especially a vow that binds for a lifetime and affects oneself, one’s spouse, one’s children, and society. This essay provides an account of ideal romantic marriage, arguing that John Stuart Mill’s On Liberty provides an excellent foundation for constructing such an account. Neither dead dogma nor living truth is a healthy model for marriage, so a hybrid model of marriage, living dogma, is developed. The importance of the marital vow becomes apparent as the living dogma account is revealed, and this examination yields a model for how to decide when and whom to marry.  相似文献

Aristotelian relativism about the future (as recently defended by MacFarlane (2003)) claims that a prediction made on Monday, such as ‘It will rain’, can be indeterminate on Monday but determinate on Tuesday. A serious objection to this intuitively appealing view is that it cannot coherently be attested: for if it is attested on Monday, then our blindness to what the future holds precludes attesting that the prediction is determinate on Tuesday, and if it is attested on Tuesday (when, suppose, it rains), then the fact that it rains precludes attesting that the prediction is indeterminate on Monday. In this paper, I focus on Moruzzi and Wright (2009)’s recent development of this objection and argue that it fails. This result removes a major obstacle to defending the Aristotelian view.  相似文献

Research examining the consequences of perspective-taking on cognition suggests that through perceiver–target overlap, perspective-taking can lead to greater valuing of targets, greater helping of targets, and a reduction in stereotyping of targets and the groups to which they belong. Research has also begun to focus more closely on the ways perceivers come to think and act like targets. This research, however evocative, is not conclusive. The current studies set out to provide firmer support. Reported here, two studies found that perspective-taking influences perceiver–target overlap, which mediates changes in self-concept (ratings of the self on researcher-related attributes and beliefs after taking the perspective of a researcher in Study 1 and attitudes toward African Americans after taking the perspective of a racist in Study 2). In the same studies, overlap simultaneously mediated valuing of the targets (target ratings on positive attributes in Study 1 and liking for the target in Study 2).  相似文献

Cultural differences in process-focused versus person-focused themes were examined using both cultural artifacts (Study 1) and self-reports (Study 2). In Study 1, the contents of Chinese and American graduation and encouragement cards were analyzed for their relative emphasis on person- versus process-focused themes. Person-focused themes center on recipients' stable traits and abilities, and their emotional well-being. In contrast, process-focused themes dwell on the recipients' hard work and effort, and emphasize the importance of continued self-improvement and growth. Messages on Chinese cards were significantly more process than person focused. The reverse was true of American cards. Chinese cards also contained more process-focused (e.g., winding roads) than person-focused images (e.g., student standing on a pedestal). American cards contained more person-focused than process-focused images, although this difference was significant only among encouragement cards. In Study 2, we presented Chinese and American participants with graduation card messages differing in focus. Chinese parents indicated that they would be more likely to select and Chinese students indicated that they would be more likely to receive process- than person-themed graduation card messages. American parents and students showed no effects of message focus. The findings illustrate how cultural beliefs are reflected in cultural artifacts and personal preferences.  相似文献

Several theorists have suggested that impulsivity can be understood as a joint function of the behavioral approach (BAS) and behavioral inhibition systems (BIS). After resolving questions concerning the measurement of impulsivity and BAS, this study examined the relationships among risky health behaviors, impulsivity, BIS, and BAS. Utilizing a sample of undergraduates (N = 904), a structural model was tested in which BAS and BIS predicted impulsivity, which, in turn, predicted risky behavior. Fit indices were acceptable, but not good. A modified version of the model showed a statistically significant negative relationship between BAS and risky behaviors. However, the fit indices were not unequivocally supportive of the need to include that path. Overall, the data suggest that impulsivity is the joint result of countervailing motivational forces and that it partially or fully mediates the influence of BIS and BAS on risky health behavior.  相似文献

A quantitative and qualitative study tested Erikson's ego developmental hypotheses regarding the positive relationship between generativity and intimacy. At age 26, participants (N = 100) told 2 stories about "relationship-defining moments," one about a romantic partner, and another about a same-sex friend. Levels of relationship intimacy were coded from these narratives. "True love" and "true friendship" themes arose as the most prototypical, highly intimate stories. Romantic intimacy and friendship intimacy as coded from narratives each contributed uniquely to the prediction of generative concern; as intimacy in each domain increased, so did generative concern. This relationship remained statistically significant, even when controlling for gender, current romantic relationship status, subjective well-being, optimism, and depressive symptoms. Results suggest that our "relationship-defining moment" narrative task is a useful tool for examining development in emerging adulthood and that intimacy may be an important precursor to generative concern in early adulthood, consistent with Erikson's model.  相似文献

Unmitigated agency (UA), a gender-linked characteristic, has been associated with poorer cancer adjustment. Support from one's social network typically predicts adjustment but may be poorly matched to UA. The influence of UA on the utility of social support on adjustment over time is examined. Men with cancer (N=55) were assessed initially and 6 months later on three indicators of adjustment. Multilevel modeling analyses varied by adjustment indicator. UA was associated with increased cancer-related psychosocial symptoms but not depressive symptoms or cancer-related thought intrusion. Social support predicted fewer depressive symptoms and less cancer-related thought intrusion. However, a cross-level interaction revealed that the utility of social support on cancer-related thought intrusion was weaker for men with greater levels of UA. Men with cancer likely respond differently to changes in social support depending on their endorsement of UA.  相似文献
