Political Animals: Luck, Love and Dignity

Human beings are both needy and dignified. How should we think about the relationship between our neediness and our worth? Card argues well that our vulnerability to luck is intertwined in the very conditions of moral agency. We can see the merit of her approach even more clearly by turning to some difficulties the Stoics have in preserving dignity while removing vulnerability. Stoicism does, however, help us to sort through the difficulties involved as we try to combine love of particular people with respect for all human life. Richardson is correct to suggest that love itself can animate the concern for all humanity; I also agree with him that institutions must play a major role in any solution to problems of inequality between nations. Although the “capabilities approach” offers an attractive account of one part of the goal of just political institutions, combining, as Moody-Adams suggests, respect for difference with a commitment to universal norms, I now believe that the capabilities account should be combined with a form of Rawlsian political liberalism that protects spaces within which citizens may pursue the good as they understand it.     

Far Away Now: Time and Distance Revisited

Einstein claimed that we do not know what it means to say that events distant from one another are simultaneous, because there is no way to determine this operationally. Reichenbach and Grunbaum claimed that determinate time relations just do not exist among events not connectible by a causal signal and that, therefore, such relations can, within certain limits, be stipulated by convention. But I argue that the independent existence of such relations is demonstrated by asking and answering a series of questions based on the intelligibility, though not the existence, of faster-than-light signals. I further argue that (1) only by demonstrating the unintelligibility of such questions and their answers can the conventionality thesis be maintained; (2) none of the available arguments to show such unintelligibility works; and (3) the conventionality thesis is therefore false.     

The Virtue of Nussbaum's Essentialism

This paper shows that Nussbaum's Aristotelian essentialism effectively combines resources for constructive social criticism (even in "traditional" societies) with concern for the concrete particulars of realized ways of life. Many critics of Nussbaum's views have failed to appreciate its many virtues in this regard. Yet Nussbaum's confidence in the broad possibilities of internal social criticism demands a better account of the moral openness of human cultures than anything Nussbaum has herself provided. Even Nussbaum's reading of Aristotle – as well as the ethical antirelativism on which it depends – demands a richer account than Nussbaum has so far offered of the essential openness of human world interpretations.

A Solution to the Paradox of Analysis

This essay attempts to solve the so-called paradox of analysis: if one is to have any questions about x , one must know x ; but if one knows x , one has no questions about x . The obvious solution is this: one can inquire into x if one knows some, but not all, of x 's parts. But this solution is erroneous. Let x ' be those parts of x with which one is acquainted, and let S be the percipient in question. As with x , either S knows x ', in which case he has no questions about it; or S does not know x ', in which case he has no questions about it.
My solution is this. Perception and cognition give us, not the thing-in-itself, but a certain analogue of the thing-in-itself. To inquire into x , it is necessary to know not x , but only some analogue of x ; and to learn more about x is to become acquainted with increasingly precise analogues of x .     

Is Wittgenstein's Resort to Ordinary Language an Appeal to Empirical facts?

There are two widely held views in the literature as regards Wittgenstein's philosophy. One says that Wittgenstein in his later work appeals to ordinary language in his effort to show how the philosophical problems can be dissolved, and the other says that his investigation is a grammatical one. This paper undertakes to examine what is meant by a grammatical investigation, especially in view of the fact that this investigation relies on empirical facts that have to do with linguistic usage. The examination is carried out by concentrating on what Wittgenstein has to say on the issue of knowledge – in particular, how the way we use the word contributes to the dismissal of Moore's answer to the challenge of scepticism. The conclusion is that Wittgenstein's resort to ordinary language is not typically empirical. The examples of ordinary usage that he cites may be contingent, but they could not have been different given the language games they are part of. The correct use of words Wittgenstein appeals to is not fixed by some kind of essence, but neither is it decided by a majority rule. It gets entrenched in a complex nexus of practices. Wittgenstein's reference to "use" instead of 'usage"and to "linguistic facts" instead of "sociological facts" lends support more to a logical than to an empirical investigation.     

Ranking Theory and Conditional Reasoning

Ranking theory is a formal epistemology that has been developed in over 600 pages in Spohn's recent book The Laws of Belief, which aims to provide a normative account of the dynamics of beliefs that presents an alternative to current probabilistic approaches. It has long been received in the AI community, but it has not yet found application in experimental psychology. The purpose of this paper is to derive clear, quantitative predictions by exploiting a parallel between ranking theory and a statistical model called logistic regression. This approach is illustrated by the development of a model for the conditional inference task using Spohn's (2013) ranking theoretic approach to conditionals.     

内容和形式对毒品成瘾者条件推理的影响

本研究通过比较推理内容与推理形式对毒品成瘾者推理成绩的影响,以探究影响毒品成瘾者能力成绩的主要内在机制。实验采用了2(四卡片形式vs选择项形式)×2(描述性规则vs社会契约规则)混合设计,以240名男性戒毒人员为研究对象,考察他们在不同推理内容与不同推理形式下的条件推理作业成绩。结果发现:(1)就规则内容来看,描述性规则内容在选择项形式上的得分好于四卡片形式,社会契约规则内容在两种呈现形式下的成绩没有显著差异;(2)就规则呈现形式来看,四卡片形式下的描述性规则得分显著地低于社会契约规则得分; 选择项形式下两类规则内容得分无显著差异。结果表明:毒品成瘾者的条件推理行为既受到推理内容的影响,也受到逻辑规则呈现形式的影响。     

关于条件推理的ERP研究

以抽象的条件命题作为实验材料,测定13名大学生在完成MP、AC、DA、MT推理（推测判断任务）和基线任务（记忆判断任务）时的事件相关电位（ERP）,初步探讨不同推理类型的脑内时程动态变化。这是使用ERP技术来研究条件推理脑机制的初步尝试。结果发现,五种任务所诱发的ERP早成分均不存在显著差异,在头皮前部的左外侧额区和左颞区,MP与DA推理与基线任务相比,均诱发一个更明显的晚期正成分（450-1100ms）,在右外侧额区则诱发一个更明显的晚期负成分（450~1100ms）;与之相反,MT与AC推理与基线任务相比,在左侧诱发一个更明显的晚期负成分（450~1100ms）,在右侧诱发一个更明显的晚期正成分（450~1100ms）,这一结果可能是由于左右脑在推理中的认知功能以及四种推理类型之间存在的差异所致,同时也表明推测过程主要激活了左右侧的前额部、颞叶等区域,基本支持Goel等人的双加工理论     

Reasoning from Classifications and Definitions

In this paper we analyze the uses and misuses of argumentation schemes from verbal classification, and show how argument from definition supports argumentation based on argument from verbal classification. The inquiry has inevitably included the broader study of the concept of definition. The paper presents the schemes for argument from classification and for argument from definition, and shows how the latter type of argument so typically supports the former. The problem of analyzing arguments based on classification is framed in a structure that reveals the crucial role it plays in the persuasion process. The survey of the literature includes the work of Hastings, Perelman, Kienpointner and Schiappa, but still finds much of value in Aristotle. Lessons drawn from Aristotle’s Topics are shown to be useful for developing new tools for assessing definitions and arguments from definition.

Aristotle,Akrasia, and the Place of Desire in Moral Reasoning

This paper serves both as a discussion of Henry’s (Ethical Theory Moral Practice, 5:255–270, 2002) interpretation of Aristotle on the possibility of akrasia – knowing something is wrong and doing it anyway – and an indication of the importance of desire in Aristotle’s account of moral reasoning. As I will explain, Henry’s interpretation is advantageous for the reason that it makes clear how Aristotle could have made good sense of genuine akrasia, a phenomenon that we seem to observe in the real world, while maintaining non-trivial distinctions between temperance (sôphrosunê), self-indulgence (akolasia), self-control (enkrateia) and akrasia. There are, however, some interpretive challenges that follow from Henry’s account and this paper is intended to explain and resolve those.     

条件推理中的二元效应初探

通过预备实验选取前件(或后件)是二元(或多元)的5种条件命题的4种推理形式作为实验材料,以大学本科生为被试,考察了五种不同条件命题类型对4种推理结果的影响.结果表明命题类型、推理规则以及两者的交互作用都非常显著.这个结果进一步验证了条件推理的集合映射模型.     

情绪状态对大学生条件推理的影响

采用不同情绪效价的电影片断诱发大学生不同的情绪,并运用眼动仪器记录条件推理的过程和结果,探讨了不同情绪状态对条件推理的影响状况。实验采用3（情绪组别：积极情绪、消极情绪、中性情绪）×4（推理形式：MP、DA、AC、MT）的混合实验设计。研究结果发现,中性情绪状态下的条件推理成绩显著地高于积极和消极情绪状态,结果支持抑制假说。     

条件推理的类比转换运用

该文通过2个实验研究旨在探究将演绎推理和类比推理结合在一起的四卡条件推理的类比转换运用的特点。结果表明：1）假设检验的条件推理过程在特定的实验条件下,表现出推理过程转换的心理加工特点;2）改善问题的陈述形式,使之和样例问题一样,能够降低推理过程转换的难度,促进推理过程转换的成绩;3）2个样例归纳的图式促进同形问题的解答,却对推理转换过程有抑制作用。     

条件推理和选择任务的关系：选择任务中的条件推理逻辑

要求大学生被试在相同的情境和规则下先后完成选择任务和条件推理任务,从而系统考察两项条件命题任务之间的关系。结果表明,当规则的语义表征意义为条件命题和反条件命题时,两项任务的反应模式具有一致性;当为双向条件和非条件命题时,两项任务的反应模式出现了分歧,而且四种推理形式和四张卡片之间不存在直接的对应关系。两项条件命题任务之间的关系表现在,它们可能享有共同的语义关系表征空间,但推理过程和策略有所不同。     

Probabilistic Logic Under Coherence, Conditional Interpretations, and Default Reasoning

We study a probabilistic logic based on the coherence principle of de Finetti and a related notion of generalized coherence (g-coherence). We examine probabilistic conditional knowledge bases associated with imprecise probability assessments defined on arbitrary families of conditional events. We introduce a notion of conditional interpretation defined directly in terms of precise probability assessments. We also examine a property of strong satisfiability which is related to the notion of toleration well known in default reasoning. In our framework we give more general definitions of the notions of probabilistic consistency and probabilistic entailment of Adams. We also recall a notion of strict p-consistency and some related results. Moreover, we give new proofs of some results obtained in probabilistic default reasoning. Finally, we examine the relationships between conditional probability rankings and the notions of g-coherence and g-coherent entailment.     

Necessity, Sufficiency, and Perspective Effects in Causal Conditional Reasoning

A growing body of research indicates that in causal conditional reasoning, the conclusion that P is necessary for Q is suppressed where alternative conditions for Q are available. Similarly, the conclusion that P is sufficient for Q is suppressed where disabling conditions for P or additional requirements for Q are available. This paper describes experiments in which these factors were used to produce 'perspective effects' in causal contexts that appear identical to the perspective effects found in previous research with deontic tasks. It is therefore proposed that deontic perspective effects are themselves also attributable to the influence of pragmatic factors upon perceived necessity and sufficiency. A generalized theory based on a modification of the mental model theory of deontic reasoning is presented, which accounts for perspective effects across the two domains.     

Immigration from the perspective of hosts and immigrants: Roles of psychological essentialism and social identity

Implicit person theory research can be conceptualized within the framework of psychological essentialism. Essentialist beliefs are associated with entity theories and both predict phenomena such as stereotyping. The present research extended previous work on the links between implicit theories and social identity processes, examining how essentialist beliefs are associated with social identification and processes related to prejudice and intergroup perception. After developing a new measure of essentialist beliefs in Study 1, Study 2 showed that these beliefs were associated with negative bias towards immigrants, particularly when participants were primed with an exclusive social identity. In Study 3, essentialist beliefs among immigrants moderated their adoption of Australian identity as a self-guide during acculturation. Essentialist beliefs therefore play a significant role in the psychology of social identity.
