Gaucher disease is a rare, chronic,ethnic-specific genetic disorder affecting Jewsof Eastern European descent. It is extremelyexpensive to treat and presents difficultdilemmas for officials and patients in Israelwhere many patients live. First, high-cost,high-benefit, but low volume treatment forGaucher creates severe allocation dilemmas forpolicy makers. Allocation policies driven bycost effectiveness, age, opportunity or needmake it difficult to justify funding. Processoriented decision making based on terms of faircooperation or decisions invoking the ``rule ofrescue' risk discriminating against minoritieswho may already suffer from inequitabledistribution of heath care resources. Apartfrom cost, Gaucher disease prompts questionsabout abortion. Unlike severe geneticdisorders, Gaucher offers no grounds forabortion and, in many ways, is analogous togender based abortions that are prohibitedregardless of fetal age. Finally, Gaucherraises concerns about the disclosure of geneticinformation. These affect potential carriersasked to participate in population studies andcarriers and patients who must considerdisclosure to others. These concerns weigh theright to privacy against communal interests andbilateral commitments. 相似文献

Philip Pettit has argued that universalizability entails consequentialism. I criticise the argument for relying on a question-begging reading of the impartiality of universalization. A revised form of the argument can be constructed by relying on preference-satisfaction rationality, rather than on impartiality. But this revised argument succumbs to an ambiguity in the notion of a preference (or desire). I compare the revised argument to an earlier argument of Pettit’s for consequentialism that appealed to the theoretical virtue of simplicity, and I raise questions about the force of appeal to notions like simplicity and rationality in moral argument. 相似文献

This article has three main parts, Section 2 considers the nature and extent to which individuals who are well-off have a moral obligation to aid the worlds needy. Drawing on a pluralistic approach to morality, which includes consequentialist, virtue-based, and deontological elements, it is contended that most who are well-off should do much more than they do to aid the needy, and that they are open to serious moral criticism if they simply ignore the needy. Part one also focuses on the United States, and illustrates both how incredibly wealthy the U.S. is and some of the spending habits of its citizens; however, its considerations apply to the well-off generally. Section 3 considers whether justice provides reasons for helping the needy. Noting that justice in an extremely complex notion, it discusses numerous considerations relevant to justices scope and implications, including an extended Rawlsian conception of justice, an absolute conception, a comparative conception, the distinction between natural and social justice, and various elements of common-sense morality. Section 2 also distinguishes between agent-relative justice-based reasons, which are relevant to whether we act justly, and agent-neutral justice-based reasons, which are relevant to whether we have reasons of justicefor acting. Correspondingly, it argues that even if one can ignore the needy without acting unjustly, as philosophers like Robert Nozick and Jan Narveson contend, there may be powerful reasons of justicefor addressing their plight. Section 4 briefly address the responsibilities of international organizations like the World Bank, the International Monetary Fund (IMF), and World Trade Organization (WTO). Drawing on Section 2, it is suggested that in addition to standard reasons to act justlytowards needy members of the worlds community, there will be reasons of justicefor such organizations to aid the needy in both present, and future, generations. The article concludes by contending that the well-off in countries like the U.S. have reason to view international organizations like the World Bank, IMF, and WTO as their agents, and to seek to insure that they alleviate misfortunes amongst the worlds needy. 相似文献

Many in the informal logic tradition distinguish convergent from linked argument structure. The pragma-dialectical tradition distinguishes multiple from co-ordinatively compound argumentation. Although these two distinctions may appear to coincide, constituting only a terminological difference, we argue that they are distinct, indeed expressing different disciplinary perspectives on argumentation. From a logical point of view, where the primary evaluative issue concerns sufficient strength of support, the unit of analysis is the individual argument, the particular premises put forward to support a given conclusion. Structure is internal to this unit. From a dialectical point of view, where the focus concerns how well a critical discussion comes to a reasoned conclusion of some disputed question, the argumentation need not constitute a single unit of argument. The unit of dialectical analysis will be the entire argumentation made up of these several arguments. The multiple/co-ordinatively compound distinction is dialectical, while the linked/convergent distinction is logical. Keeping these two pairs of distinctions separate allows us to see certain attempts to characterize convergent versus linked arguments as rather characterizing multiple versus co-ordinatively compound arguments, in particular attempts of Thomas, Nolt, and Yanal, and to resolve straightforwardly conflicts, tensions, or anomalies in their accounts. Walton's preferred Suspension/Insufficient Proof test to identify linked argument structure correctly identifies co-ordinatively compound structure. His objection to using the concept of relevance to explicate the distinction between linked and convergent structure within co-ordinatively compound argumentation can be met through explicating relevance in terms of inference licenses. His counterexample to the Suspension/No Support test for identifying linked structure which this approach supports can itself be straightforwardly dealt with when the test is explicated through inference licenses. 相似文献

The temporal updating of an agent’s beliefs in response to a flow of information is modeled in a simple modal logic that,
for every date t, contains a normal belief operator B
t
and a non-normal information operator I
t
which is analogous to the ‘only knowing’ operator discussed in the computer science literature. Soundness and completeness
of the logic are proved and the relationship between the proposed logic, the AGM theory of belief revision and the notion
of plausibility is discussed.
A first draft of this paper was presented at the Workshop on Belief Change in Rational Agents: Perspectives from Artificial
Intelligence, Philosophy and Economics, Dagstuhl (Germany), August 2005.

样例学习条件下的因果力估计 总被引:2,自引:1,他引:1
在逐个呈现因果样例的条件下,考察单一因果关系因果力估计的特点,同时检验联想解释,概率对比模型,权重DP模型,效力PC理论和pCI规则。实验让65名大学生被试估计不同化学药物影响动物基因变异的能力。实验结果表明:(1)对产生原因的因果力估计符合权重DP模型;(2)对预防原因的因果力估计较多符合效力PC理论;(3)因果力估计具有复杂多样性,难以用统一的模式加以描述和概括。 相似文献
