彼彻姆和查瑞斯的原则主义进路及其改进

在全球化、多元化背景下,彼彻姆和查瑞斯通过寻找普世原则来容纳道德多元主义和避免道德相对主义,进而为医学伦理学提供一系列清晰、明确、有效的道德规范的努力无疑是可贵的,但其原则主义存在的突出问题是反思平衡方法在实践中不能有效解决根本性的道德冲突。针对这一不足,我们尝试提出解决道德冲突的更有希望的思路。

G. H. Mead's alleged behaviorism

This paper seeks to clarify those conceptual foundations of G.H. Mead's social behaviorism which are assumed, but not made explicit, in that writer's well-known volume Mind, Self and Society. These foundations are shown to be an outgrowth of Mead's early commitment to the organic conception of conduct underlying the psychological functionalism of the Chicago School. Further light is shed upon Mead's position by pointing out the fundamental differences between his model of conduct and that characteristic of the behaviorist tradition in American psychology.     

Public Health Principlism: The Precautionary Principle and Beyond

What accounts for the continued lack of clarity over the legal procedures for the patenting of DNA sequences? The patenting system was built for a "bricks-and-mortar" world rather than an information economy. The fact that genes are both material molecules and informational systems helps explain the difficulty that the patent system is going to continue to have.     

The Limits of Principlism and Recourse to Theory: The Example of Telecare

Principlism is the approach promoted by Beauchamp and Childress for addressing the ethics of medical practice. Instead of evaluating clinical decisions by means of full-scale theories from moral philosophy, Beauchamp and Childress refer people to four principles—of autonomy, beneficence, nonmaleficence, and justice. Now it is one thing for principlism to be invoked in an academic literature dwelling on a stock topic of medical ethical writing: end-of-life decisions, for example. It is another when the topic lies further from the mainstream. In such cases the cost of reaching for the familiar Beauchamp and Childress framework, with its formulaic set of concerns, may be to miss something morally important. After discussing an example of the sort of academic literature I have in mind, I propose to distinguish the uses of the formulaic from the uses of the more unapologetically theoretical in applied ethics, and to suggest that the latter can make up for some of the limitations of the former. This is not to say that the more theoretical literature has no limitations of its own, or that it should take the place of the formulaic. On the contrary, there is room in applied ethics and a use in applied ethics for both. But there is a sense in which there is a greater dependence of principlism on theory than the other way round, and at the end I try to spell out the significance of this fact.     

Casuistry and Principlism: The Convergence of Method in Biomedical Ethics

Casuistry and principlism are two of the leading contenders to be considered the methodology of bioethics. These methods may be incommensurable since the former emphasizes the examination of cases while the latter focuses on moral principles. Conversely, since both analyze cases in terms of mid-level principles, there is hope that these methods may be reconcilable or complementary. I analyze the role of principles in each and thereby show that these theories are virtually identical when interpreted in a certain light. That is, if the gaps in each method are filled by a concept of judgment or Aristotelian practical wisdom, these methods converge.     

Mating competitors increase religious beliefs

It has been presumed that religiosity has an influence on mating behavior, but here we experimentally investigate the possibility that mating behavior might also influence religiosity. In Experiment 1, people reported higher religiosity after looking at mating pools consisting of attractive people of their own sex compared to attractive opposite sex targets. Experiment 2 replicated the effect with an added control group, and suggested that both men and women become more religious when seeing same-sex competitors. We discuss several possible explanations for these effects. Most broadly, the findings contribute to an emerging literature on how cultural phenomena such as religiosity respond to ecological cues in potentially functional ways.     

Testing alleged mediumship: Methods and results

Mediums claim to be able to communicate with the deceased. Such claims attract a considerable amount of public interest and, if valid, have important implications for many areas of psychology. For over 100 years, researchers have tested alleged mediums. This work has obtained mixed results and provoked a considerable amount of methodological debate. This paper reviews the key issues in this debate, describes how the authors devised a method of testing that aimed to prevent the many problems that have hindered past research, and how they then used this method to test several professional mediums. The results of this work did not support the existence of genuine mediumistic ability. Competing interpretations of these results are discussed, along with ways in which the methodology presented in the paper could be used to assess conceptually similar, but non‐paranormal, claims made in clinical, occupational and forensic contexts.     

Knowledge of resources and competitors in human foraging

The allocation of human participants to resources was studied by observing the population dynamics of people interacting in real time within a common virtual world. Resources were distributed in two spatially separated pools with varying relative reinforcement rates (50–50, 65–35, or 80–20). We manipulated whether the participants could see each other and the distribution of the resources. When the participants could see each other but not the resources, the richer pool was underutilized. When the participants could see the resources but not each other, the richer pool was overutilized. In conjunction with prior experiments that correlated the visibility of agents and resources (Goldstone & Ashpole, 2004), these results indicate that participants’ foraging decisions are influenced by both forager and resource information. The results suggest that the presence of a crowd at a resource is a deterring, rather than an attractive, factor. Both fast and slow oscillations in the harvesting rates of the pools across time were revealed by Fourier analyses. The slow waves of crowd migration were most prevalent when the resources were invisible, whereas the fast cycles were most prevalent when the resources were visible and the participants were invisible.     

I. On the alleged inconsistency,moral insensitivity and fanaticism of pacifism

All the standard and some esoteric objections to pacifism are refuted, either directly or (as with the charge of impracticality) in outline. Familiar arguments to the inconsistency and irresponsibility of pacifism are shown to turn upon illegitimately construing pacifist activities such as resisting, preventing, and defending as involving violence. Several arguments against pacifism from violence as a lesser evil turn out to be fallacious; some involve the erroneous assumption that violence is the only evil, but some lead into what pacifism can simply concede, moral dilemmas. It is argued that pacifism is not a form of fanaticism, is not morally insensitive, does not imply anarchism, or vegetarianism, is not completely impractical, and can be positively underpinned. In the course of the arguments various types of pacifism are classified, pacifism is distinguished from nonviolent action, and pacifism and, differently, pacificity are disassociated from passivity: The question of a more general characterization of violence (which is different from force) emerges as a crucial issue, along with the problem of integrating pacifism into a more comprehensive moral position.     

Reflexive Principlism as an Effective Approach for Developing Ethical Reasoning in Engineering

An important goal of teaching ethics to engineering students is to enhance their ability to make well-reasoned ethical decisions in their engineering practice: a goal in line with the stated ethical codes of professional engineering organizations. While engineering educators have explored a wide range of methodologies for teaching ethics, a satisfying model for developing ethical reasoning skills has not been adopted broadly. In this paper we argue that a principlist-based approach to ethical reasoning is uniquely suited to engineering ethics education. Reflexive Principlism is an approach to ethical decision-making that focuses on internalizing a reflective and iterative process of specification, balancing, and justification of four core ethical principles in the context of specific cases. In engineering, that approach provides structure to ethical reasoning while allowing the flexibility for adaptation to varying contexts through specification. Reflexive Principlism integrates well with the prevalent and familiar methodologies of reasoning within the engineering disciplines as well as with the goals of engineering ethics education.     

On the alleged ineffability of death

A number of recent theorists, all proceeding on the assumption that there is no afterlife, argue that the notion of one's own death defies comprehension in ways that have important implications. Some argue this "ineffability" of death precludes a rational decision to die. Dr. Edwin Shneidman maintains that it makes the notion of our own death unintelligible to each of us. In this paper, these arguments are criticized. It is maintained that death is not so inscrutible as these theorists would have us believe.     

Selective and nonselective inhibition of competitors in picture naming

The present study examined the relation between nonselective inhibition and selective inhibition in picture naming performance. Nonselective inhibition refers to the ability to suppress any unwanted response, whereas selective inhibition refers to the ability to suppress specific competing responses. The degree of competition in picture naming was manipulated by presenting targets along with distractor words that could be semantically related (e.g., a picture of a dog combined with the word cat) or unrelated (tree) to the picture name. The mean naming response time (RT) was longer in the related than in the unrelated condition, reflecting semantic interference. Delta plot analyses showed that participants with small mean semantic interference effects employed selective inhibition more effectively than did participants with larger semantic interference effects. The participants were also tested on the stop-signal task, which taps nonselective inhibition. Their performance on this task was correlated with their mean naming RT but, importantly, not with the selective inhibition indexed by the delta plot analyses and the magnitude of the semantic interference effect. These results indicate that nonselective inhibition ability and selective inhibition of competitors in picture naming are separable to some extent.     

On the alleged impossibility of coherence

If coherence is to have justificatory status, as some analytical philosophers think it has, it must be truth-conducive, if perhaps only under certain specific conditions. This paper is a critical discussion of some recent arguments that seek to show that under no reasonable conditions can coherence be truth-conducive. More specifically, it considers Bovens and Hartmann’s and Olsson’s “impossibility results,” which attempt to show that coherence cannot possibly be a truth-conducive property. We point to various ways in which the advocates of a coherence theory of justification may attempt to divert the threat of these results.     

On the alleged memory-undermining effects of daydreaming

In three experiments, we examined the memory-undermining effects of daydreaming for (un)related stimuli. In Experiments 1 and 2, we tested whether daydreaming fosters forgetting of semantically interrelated material and hence, catalyzes false memory production. In Experiment 3, we examined the memory effects of different daydreaming instructions. In Experiment 1, daydreaming did not undermine correct recall of semantically interrelated words, nor did it affect false memories. In Experiment 2, we again failed to find that daydreaming exerted memory-undermining effects a. In Experiment 3, no memory effects were obtained using different daydreaming instructions. Together, our studies fail to show appreciable memory-undermining effects of daydreaming.
