Applied Logic without Psychologism 总被引:1,自引:0,他引:1
Gregory Wheeler 《Studia Logica》2008,88(1):137-156
Logic is a celebrated representation language because of its formal generality. But there are two senses in which a logic
may be considered general, one that concerns a technical ability to discriminate between different types of individuals, and
another that concerns constitutive norms for reasoning as such. This essay embraces the former, permutation-invariance conception
of logic and rejects the latter, Fregean conception of logic. The question of how to apply logic under this pure invariantist
view is addressed, and a methodology is given. The pure invariantist view is contrasted with logical pluralism, and a methodology
for applied logic is demonstrated in remarks on a variety of issues concerning non-monotonic logic and non-monotonic inference,
including Charles Morgan’s impossibility results for non-monotonic logic, David Makinson’s normative constraints for non-monotonic
inference, and Igor Douven and Timothy Williamson’s proposed formal constraints on rational acceptance. 相似文献

Nearly all of the ways philosophers currently attempt to define the terms ‘representation’ and ‘function’ undermine the scientific
application of those terms by rendering the scientific explanations in which they occur vacuous. Since this is unacceptable,
we must develop analyses of these terms that avoid this vacuity.
Robert Cummins argues in this fashion in Representations, Targets, and Attitudes. He accuses ‘use theories’ of representational content of generating vacuous explanations, claims that nearly all current
theories of representational content are use theories, and offers a non-use theory of representational content which avoids
explanatory vacuity. One task I undertake in this article is to develop an alternative non-use theory which avoids an objection
fatal to that theory.
My second task is to adapt Cummins’ argument to criticize most current analyses of ‘function,’ which undermine scientific
explanation in an analogous way. Though Cummins does not explicitly argue in this manner, his own analysis of ‘function,’
by avoiding any appeal to use, avoids the explanatory vacuity to which they succumb. Consequently, I endorse Cummins’ notion
of function.
However, although use theories fail as analyses of the terms ‘representation’ and ‘function,’ they can still make significant
contributions to the sciences employing these terms. For, while philosophers seeking to define ‘representation’ and ‘function’
must avoid incorporating representational and functional uses into their definitions, scientists must still find a way to
determine which representations and functions are being used. Suitably re-construed use theories of representation and function
may in many cases assist them in this task. 相似文献

The present paper introduces a belief merging procedure by majority using the standard format of Adaptive Logics. The core
structure of the logic ADM
c
(Adaptive Doxastic Merging by Counting) consists in the formulation of the conflicts arising from the belief bases of the agents involved in the procedure. A strategy
is then defined both semantically and proof-theoretically which selects the consistent contents answering to a majority principle.
The results obtained are proven to be equivalent to a standard majority operator for bases with partial support. 相似文献

Do 18-month-olds understand that an agent's false belief can be corrected by an appropriate, though not an inappropriate, communication? In Experiment 1, infants watched a series of events involving two agents, a ball, and two containers: a box and a cup. To start, agent1 played with the ball and then hid it in the box, while agent2 looked on. Next, in agent1's absence, agent2 moved the ball from the box to the cup. When agent1 returned, agent2 told her "The ball is in the cup!" (informative-intervention condition) or "I like the cup!" (uninformative-intervention condition). During test, agent1 reached for either the box (box event) or the cup (cup event). In the informative-intervention condition, infants who saw the box event looked reliably longer than those who saw the cup event; in the uninformative-intervention condition, the reverse pattern was found. These results suggest that infants expected agent1's false belief about the ball's location to be corrected when she was told "The ball is in the cup!", but not "I like the cup!". In Experiment 2, agent2 simply pointed to the ball's new location, and infants again expected agent1's false belief to be corrected. These and control results provide additional evidence that infants in the second year of life can attribute false beliefs to agents. In addition, the results suggest that by 18 months of age infants expect agents' false beliefs to be corrected by relevant communications involving words or gestures. 相似文献

‘Evidentialism’ is the conventional name (given mainly by its opponents) for the view that there is a moral duty to proportion
one’s beliefs to evidence, proof or other epistemic justifications for belief. This essay defends evidentialism against objections
based on the alleged involuntariness of belief, on the claim that evidentialism assumes a doubtful epistemology, that epistemically
unsupported beliefs can be beneficial, that there are significant classes of exceptions to the evidentialist principle, and
other shabby evasions and alibis (as I take them to be) for disregarding the duty to believe according to the evidence. Evidentialism
is also supported by arguments based on both self-regarding and other-regarding considerations. 相似文献

We investigated the development of code specific representations of different kinds of information in long term memory. Forty
second graders, 40 sixth graders and 40 adults learned the associations between 12 pictures and one position each in a 4 × 3
grid of squares, 12 pictures and 1 of 12 monosyllabic words each or 12 pictures and 1 of 12 faces. After a 3 min distractor
task, a picture was presented in the retrieval phase, and the associated position, word or face had to be selected. Performance
in the verbal condition improved as a function of age, while performance in the spatial condition turned out to be independent
of age, and the performance in the facial condition showed a difference between both child groups and the adults. The results
revealed a developmental difference of code specific representation of different kinds of information. 相似文献

In this article I argue that two received accounts of belief and assertion cannot both be correct, because they entail mutually
contradictory claims about Moore’s Paradox. The two accounts in question are, first, the Action Theory of Belief (ATB), the
functionalist view that belief must be manifested in dispositions to act, and second, the Belief Account of Assertion (BAA),
the Gricean view that an asserter must present himself as believing what he asserts. It is generally accepted also that Moorean
assertions are absurd, and that BAA explains why they are. I shall argue that ATB implies that some Moorean assertions are,
in some fairly ordinary contexts, well justified. Thus BAA and ATB are mutually inconsistent. In the concluding section I
explore three possible ways of responding to the dilemma, and what implications they have for the nature of the constitutive
relationships linking belief, assent and behavioural dispositions.

In the political context of the reauthorization of federal welfare reform legislation, a nationally representative sample of 1,570 adults in the United States completed a survey examining the factors that affect attitudes and policy preferences with regard to aid for low-income individuals and families in the United States. This study utilized an innovative survey technique, the factorial survey methodology (Rossi & Nock, 1982), which allows for the simultaneous experimental manipulation of a large number of factors through the use of a vignette. This research demonstrates how the portrayal of difficulties faced by people in need and the ways in which they attempt to overcome these difficulties affect support for policies designed to aid low-income individuals and families. In addition, this study of public attitudes considers the role that psychological orientations of the evaluators play in judgments of families in need. In this case, we examined how the evaluators' belief that the world is a just place influences their evaluations of deservingness. Consistent with our expectations, we found that the more efforts the vignette subject engaged in improving her situation, the less deserving of government benefits she was judged to be by respondents with a strong belief in a just world. The reverse was found among respondents with a weaker belief: more efforts were associated with greater judgments of deservingness. 相似文献

语义启动是研究语义表征的主要范式。在过去的30年里,通过对语义启动效应的研究,词汇的语义表征理论也从符号联结发展到神经联结,其影响因素也逐步重视多方面的交互作用。究其问题,已有研究还存在很多不一致的结论,对语义内在的表征机制和学习机制缺乏深入了解,对影响语义表征的个体因素考虑不多。 相似文献
