Structural realism is an attempt to balance the competing demands of the No Miracles Argument and the Pessimistic Meta-Induction.
In this paper I trace the development of the structuralist idea through the work of one of its leading advocates, John Worrall.
I suggest that properly thought through what the structuralist is offering or should be offering is not an account of how
to divide up a theory into two parts—structure and ontology—but (perhaps surprisingly) a certain kind of theory of meaning—semantic
holism. I explain how a version of structural realism can be developed using Davidson’s theory of meaning and some advantages
this has over the Ramsey-sentence version of structuralism. 相似文献

Brogaard and Salerno (2005, Nous, 39, 123–139) have argued that antirealism resting on a counterfactual analysis of truth is flawed because it commits a conditional
fallacy by entailing the absurdity that there is necessarily an epistemic agent. Brogaard and Salerno’s argument relies on
a formal proof built upon the criticism of two parallel proofs given by Plantinga (1982, Proceedings and Addresses of the American Philosophical Association, 56, 47–70) and Rea (2000, Nous, 34, 291–301). If this argument were conclusive, antirealism resting on a counterfactual analysis of truth should probably be
abandoned. I argue however that the antirealist is not committed to a controversial reading of counterfactuals presupposed
in Brogaard and Salerno’s proof, and that the antirealist can in principle adopt an alternative reading that makes this proof
invalid. My conclusion is that no reductio of antirealism resting on a counterfactual analysis of truth has yet been provided.

Using a procedure of Hay and Jacoby [Hay, J. F., & Jacoby, L. L. (1999). Separating habit and recollection in young and older adults: Effects of elaborative processing and distinctiveness. Psychology and Aging, 14, 122–134], Korsakoff patients’ capacity to encode and retrieve elaborative, semantic information was investigated. Habits were created during initial training, whereupon cued-recall memory performance was examined, with habit opposing as well as facilitating recollection of earlier studied words. A first group of patients was instructed and tested in the same way as healthy controls and showed poor test performance. Nevertheless, when given more processing and response time, additional explanation, and explicit encouragement, a second group of patients performed similarly to healthy controls. The results suggest that, when given adequate support, Korsakoff patients are able to encode and make use of semantic, contextual, and sequential information. Word distinctiveness, however, only influenced performance of controls. 相似文献

Existing models of laterality, while often successful at describing circumscribed domains, have not been successful as explanations of the overall patterns of hemispheric asymmetries. It is therefore suggested that a new approach is needed based on shared contributions to adaptive hemispheric roles rather than functional and structural intrahemispheric similarities. This paper proposes a model of laterality, the Janus model, based on evolutionary considerations of complementary hemispheric roles. It is proposed that the left hemisphere has the role of anticipating future scenarios and choosing between them while the right hemisphere has the role of integrating ongoing information into a unitary view of the past in order to immediately detect and respond to novel and unexpected events. Evidence for these complementary roles is provided in research on motor control and semantic priming. Finally, the Janus model is contrasted with efforts to cast the frequency model as a general model of laterality. 相似文献

Metonymic verbs like start or enjoy often occur with artifact-denoting complements (e.g., The artist started the picture) although semantically they require event-denoting complements (e.g., The artist started painting the picture). In case of artifact-denoting objects, the complement is assumed to be type shifted (or coerced) into an event to conform to the verb's semantic restrictions. Psycholinguistic research has provided evidence for this kind of enriched composition: readers experience processing difficulty when faced with metonymic constructions compared to non-metonymic controls. However, slower reading times for metonymic constructions could also be due to competition between multiple interpretations that are being entertained in parallel whenever a metonymic verb is encountered. Using the visual-world paradigm, we devised an experiment which enabled us to determine the time course of metonymic interpretation in relation to non-metonymic controls. The experiment provided evidence in favor of a non-competitive, serial coercion process. 相似文献

Participants (aged 5-6 yrs, 9-10 yrs and adults) rated (using a five-point scale) grammatical (intransitive) and overgeneralized (transitive causative)(1) uses of a high frequency, low frequency and novel intransitive verb from each of three semantic classes [Pinker, S. (1989a). Learnability and cognition: The acquisition of argument structure. Cambridge, MA: MIT Press]: "directed motion" (fall, tumble), "going out of existence" (disappear, vanish) and "semivoluntary expression of emotion" (laugh, giggle). In support of Pinker's semantic verb class hypothesis, participants' preference for grammatical over overgeneralized uses of novel (and English) verbs increased between 5-6 yrs and 9-10 yrs, and was greatest for the latter class, which is associated with the lowest degree of direct external causation (the prototypical meaning of the transitive causative construction). In support of Braine and Brooks's [Braine, M.D.S., & Brooks, P.J. (1995). Verb argument strucure and the problem of avoiding an overgeneral grammar. In M. Tomasello & W. E. Merriman (Eds.), Beyond names for things: Young children's acquisition of verbs (pp. 352-376). Hillsdale, NJ: Erlbaum] entrenchment hypothesis, all participants showed the greatest preference for grammatical over ungrammatical uses of high frequency verbs, with this preference smaller for low frequency verbs, and smaller again for novel verbs. We conclude that both the formation of semantic verb classes and entrenchment play a role in children's retreat from argument-structure overgeneralization errors. 相似文献

Criticizing the works of “Western” specialists in semantics, Soviet academician M. M. Pokrovskij (1868–1942) comes to the
conclusion that social factors are essential for semantic evolution, while psychological factors constitute an intermediate
link between the “external” life of a society and the semantics of the corresponding language. This conception resembles the
general explanations of semantic evolution proposed by N. Ja. Marr (1864–1934). Nevertheless, despite a number of common points
in the semantic theories of these two researchers, Pokrovskij’s attitude towards Marr was negative: in particular, he disagreed
with the thesis of the chronological primacy of Marr’s discoveries in the domain of semantics. The article investigates why
Pokrovskij had for a long time constituted an intermediate link between Russian and “Western” “traditions” in the field of
semantics.

Recent semantic approaches to scientific structuralism, aiming to make precise the concept of shared structure between models,
formally frame a model as a type of set-structure. This framework is then used to provide a semantic account of (a) the structure
of a scientific theory, (b) the applicability of a mathematical theory to a physical theory, and (c) the structural realist’s
appeal to the structural continuity between successive physical theories. In this paper, I challenge the idea that, to be
so used, the concept of a model and so the concept of shared structure between models must be formally framed within a single
unified framework, set-theoretic or other. I first investigate the Bourbaki-inspired assumption that structures are types
of set-structured systems and next consider the extent to which this problematic assumption underpins both Suppes’ and recent
semantic views of the structure of a scientific theory. I then use this investigation to show that, when it comes to using
the concept of shared structure, there is no need to agree with French that “without a formal framework for explicating this
concept of ‘structure-similarity’ it remains vague, just as Giere’s concept of similarity between models does ...” (French,
2000, Synthese, 125, pp. 103–120, p. 114). Neither concept is vague; either can be made precise by appealing to the concept of a morphism, but it is the context (and not any set-theoretic type) that determines the appropriate kind of morphism. I make use of French’s
(1999, From physics to philosophy (pp. 187–207). Cambridge: Cambridge University Press) own example from the development of quantum theory to show that, for
both Weyl and Wigner’s programmes, it was the context of considering the ‘relevant symmetries’ that determined that the appropriate
kind of morphism was the one that preserved the shared Lie-group structure of both the theoretical and phenomenological models.

In the paper there is presented the semantic interpretation of idealism/realism controversy which is one of the most essential
issues in Ingarden’s phenomenological project of ontology. The procedure of semantic paraphrase which is contemporary developed
by Woleński, is the main interpretative tool. In the central part of the paper, there is formulated the formal theory of the
semantic framework underlying idealism/realism discourse. Finally, there are formulated some notes showing that intentional
conception of negation may be used for defending various idealistic positions.

We extend answer set programming (ASP) with, possibly infinite, open domains. Since this leads to undecidable reasoning, we restrict the syntax of programs, while carefully guarding knowledge representation mechanisms such as negation as failure and inequalities. Reasoning with the resulting extended forest logic programs (EFoLPs) can be reduced to finite answer set programming, for which reasoners are available.We argue that extended forest logic programming is a useful tool for uniformly representing and reasoning with both ontological and rule-based knowledge, as they can capture a large fragment of the OWL DL ontology language equipped with DL-safe rules. Furthermore, EFoLPs enable nonmonotonic reasoning, a desirable feature in locally closed subareas of the Semantic Web. 相似文献
