The main goal of this paper is to present and compare two approaches to formalizing cross-world comparisons like ??John might have been taller than he is?? in quantified modal logics. One is the standard method employing degrees and graded positives, according to which the example just given is to be paraphrased as something like ??The height that John has is such that he might have had a height greater than it,?? which is amenable to familiar formalization strategies with respect to quantified modal logic. The other approach, based on subjunctive modal logic, mimics the mixed indicative-subjunctive patterns typical of cross-world comparisons in many natural languages by means of explicit mood markers. This latter approach is new and should, for various reasons, appeal to linguists and philosophers. Along the way, I argue that attempts to capture cross-world comparison by means of sentential operators are either inadequate or subject to substantive logical and philosophical objections.  相似文献

Although in every inductive inference, an act of invention is requisite, the act soon slips out of notice. Although we bind together facts by superinducing upon them a new Conception, this Conception, once introduced and applied, is looked upon as inseparably connected with the facts, and necessarily implied in them. Having once had the phenomena bound together in their minds in virtue of the Conception men can no longer easily restore them back to the detached and incoherent condition in which they were before they were thus combined. The pearls once strung, they seem to form a chain by their nature. Induction has given them unity which it is so far from costing us an effort to preserve, that it requires an effort to imagine it dissolved — William Whewell, 1858. (Quoted from Butts (ed.), 1989, p. 143)  相似文献

The notion of grammatical gender is defined and criteria for assigning nouns to genders are discussed, in particular semantic and formal criteria. Data from child language acquisition show that both semantic and formal criteria can be the basis of children's overgeneralizations, although the question of to what extent more opaque semantic or formal gender assignment criteria are available to children remains to be ascertained.  相似文献

Jones' (1985) Ease of Predication hypothesis, which states that underlying differences in the semantic representation of concrete and abstract words can be explained in terms of disproportionate numbers of semantic predicates, is explored in two experiments. The results suggest that (1) the advantage shown by concrete words in terms of greater number of predicates is only apparent for words of low frequency, and (2) Jones' case of predication variable does not accurately reflect predicate distributions, or differences in imageability. Rather, it appears to represent differences in concreteness. As such, the validity of this concept as the basis of theories of semantic representation is questioned. Models based on the assumption of a "richer" semantic representation for concrete words are therefore not supported.  相似文献

It is commonly accepted, after Frege, that identity statements like “Tully is Cicero” differ from statements like “Tully is Tully”. For the former, unlike the latter, are informative. One way to deal with the information problem is to postulate that the terms ‘Tully’ and ‘Cicero’ come equipped with different informative (or cognitive) values. Another approach is to claim that statements like these are of the subject/predicate form. As such, they should be analyzed along the way we treat “Tully walks”. Since proper names can appear in predicative position we could go as far as to dismiss the sign of identity altogether, some told us. I will try to discuss the advantages and/or disadvantages of this approach and investigate whether Frege’s view that the ‘is’ of identity must be distinguished from the ‘is’ of predication (copula) can be reconciled with the fact that names can appear in predicative position.  相似文献

Three experiments demonstrate gender congruency effects (i.e., naming times of a picture are faster when the name of the target picture and a distractor noun are gender congruent) in Czech. In the first experiment, subjects named the pictures by producing gender-marked demonstrative pronouns and a noun. In the second and third experiments, subjects produced a gender-marked numeral (marked with a suffix) plus a noun. Two types of such suffixes exist in Czech. Some numerals vary in nominative singular with gender, others do not. The results show significant gender congruency effects in all experiments. They suggest that gender congruency effects can be obtained not only with free, but also with bound morphemes. In the second and third experiment the effect only emerged when the suffix was gender-marked (as opposed to gender-invariant), supporting the view that the gender congruency effect is due to competition at the level of phonological forms rather than at the grammatical level.  相似文献

Access to grammatical gender in Hebrew was examined using gender decisions and grammaticality judgments. In gender decisions, and in rejecting agreement violations, the role of gender-marking regularity was robust; irregular feminine nouns were classified more slowly and produced more errors than did regular masculine nouns. These same exception nouns, however, produced radically different results when they appeared as part of a grammatical phrase. In this context, irregular nouns were processed as quickly and accurately as were regular nouns. These findings are interpreted within a model containing two routes to grammatical gender: one that involves an abstract gender node, and another that is form-based and is assumed to play a greater role in recovery from agreement errors. We also argue that there are cross-linguistic variations in the availability and speed of the form-based route to gender. Finally, we caution that under some circumstances grammatical gender may also be retrieved through a variety of heuristics that do not necessarily reflect the normal mechanisms of access to gender.  相似文献
