Eerik Lagerspetz 《Argumentation》1995,9(2):363-370
This paper is ultimately about the nature of argumentation in general and about the nature of practical argumentation in particular. (Practical argumentation is the form of argumentation which aims at answering the question: ‘What is to be done?’) The approach adopted here is an indirect one. I analyze one traditional form of argumentive fallacyargumentum ad hominem and try to show that in some argumentative situations it is an intuitively legitimate move. These intuitions can be explained if we accept that practical argumentation is also governed by the general rules of practical rationality. 相似文献

Abstract. My comment on Ethics in an Age of Technology, volume 2 of Ian G. Barbour's Gifford Lectures, acknowledges the excellence of Barbour's depictions of the social-cum-technological problems facing humanity in the coming millennium. Barbour's proposed solutions, too, are reasonable—but usually presuppose fundamental reforms in social values, especially within the powerful industrialized societies. Without further analysis of technology and values, this seems to make such solutions “impossible dreams.” My thesis is that clear analysis of the ideal aspects of technology (as itself the embodiment of knowledge and values), plus clues from Alfred North Whitehead on the dynamics of social change, can reinforce hope even in “impossible” dreams. First, technology, though embodied in solid material machinery and powerful social institutions, is no more “solid” than constant reaffirmation of the values behind it (as was the case with the Berlin Wall). Second, great ideals, over time, have the power to help create the conditions of their own possibility. Social change is both “pushed” by coercive forces (e.g., climate changes) and “pulled” by great values (e.g., human dignity). Therefore there are practical benefits to be gained from attending to, and celebrating, even currently “impossible” dreams as they work to make themselves possible. 相似文献

The Comprehensive Ability Battery (CAB) was used to assess 18 primary mental abilities in 53 white, male prison inmates for whom highly reliable ratings of psychopathy were available. None of the correlations between ratings of psychopathy and scores on the CAB tests was significant, and the overall pattern or structure of abilities was the same for inmates with low and high ratings of psychopathy. The possibility is raised that the personality characteristics of psychopaths make them appear to be brighter and more creative than they actually are. Compared with norms for male high school students, the inmates as a group generally performed well, falling near the 50th percentile on 11 of the tests. The inmates performed significantly better than the normative sample on tests of verbal ability, esthetic judgment, aiming, and representational drawing, and significantly worse on tests of ideational fluency, spontaneous flexibility, and word fluency.This research was supported by Grant MT-4511 from the Medical Research Council of Canada. 相似文献

人与人的和谐是和谐社会的“底线要求”,人与社会的和谐是和谐社会的核心所在,而人与自然的和谐是和谐社会的基本前提。人与自然和谐集中体现为环境公正。它首先是指人与自然物种之间的种际公正,具体体现为两个维度的公正:在空间维度上,要促进国际公正、族际公正、域际公正、群际公正;在时间维度上具有代际公正意识。 相似文献

Four- and-a-half-month-old infants' (N = 100) category formation and use was studied in a series of five experiments. For each experiment, the test events featured a display composed of a cylinder and a box. Previous research showed that this display is not clearly parsed as a single unit or as two separate units by infants of this age. Immediately prior to testing, infants were shown a set of category exemplars. Knowledge about this category could help infants disambiguate the test display, which contained a novel exemplar of this category. Clear interpretation of the test display as composed of two separate units (as indicated by infants' longer looking at the move-together than at the move-apart test event) was taken as evidence of category formation and use. In Experiments 1 and 5, infants' prior experience with a set of three different boxes that were similar to the test box facilitated their segregation of the test display. Experiment 2 showed that three different exemplars are necessary: prior experience with any two of the three boxes used in Experiment 1 did not facilitate infants' segregation of the test display. Experiment 3 showed that variability in the exemplar set is necessary: prior experience with three identical boxes did not facilitate infants' segregation of the test display. Experiment 4 showed that under these conditions of very brief prior exposure, similarity between the exemplar set and test box is necessary: prior experience with three different boxes that were not very similar to the test box did not facilitate infants' segregation of the test display. Together, these findings suggest that: (a) number of exemplars, variability, and similarity in the exemplar set are important for infants' category formation, and (b) infants use their category knowledge to determine the boundaries of the objects in a display. 相似文献

The study investigated native language verbal skills among low and highly proficient bilinguals, using the WISC III verbal subtests. Highly proficient bilinguals showed a superiority for almost all verbal subtests. This finding lends support to Threshold Theory which maintains that bilinguals need to achieve high levels of linguistic proficiency before bilingualism can promote cognitive development. Our study also shows that verbal ability underlying proficiency in the native language can be generalized to a foreign language, revealing a causal connection between native and foreign language learning. 相似文献

Grammatical-specific language impairment (G-SLI) in children, arguably, provides evidence for the existence of a specialised grammatical sub-system in the brain, necessary for normal language development. Some researchers challenge this, claiming that domain-general, low-level auditory deficits, particular to rapid processing, cause phonological deficits and thereby SLI. We investigate this possibility by testing the auditory discrimination abilities of G-SLI children for speech and non-speech sounds, at varying presentation rates, and controlling for the effects of age and language on performance. For non-speech formant transitions, 69% of the G-SLI children showed normal auditory processing, whereas for the same acoustic information in speech, only 31% did so. For rapidly presented tones, 46% of the G-SLI children performed normally. Auditory performance with speech and non-speech sounds differentiated the G-SLI children from their age-matched controls, whereas speed of processing did not. The G-SLI children evinced no relationship between their auditory and phonological/grammatical abilities. We found no consistent evidence that a deficit in processing rapid acoustic information causes or maintains G-SLI. The findings, from at least those G-SLI children who do not exhibit any auditory deficits, provide further evidence supporting the existence of a primary domain-specific deficit underlying G-SLI. 相似文献

This paper considers a new class of agent dynamic logics which provide a formal means of specifying and reasoning about the agents activities and informational, motivational and practical aspects of the behaviour of the agents. We present a Hilbert-style deductive system for a basic agent dynamic logic and consider a number of extensions of this logic with axiom schemata formalising interactions between knowledge and commitment (expressing an agent s awareness of her commitments), and interactions between knowledge and actions (expressing no learning and persistence of knowledge after actions). The deductive systems are proved sound and complete with respect to a Kripke-style semantics. Each of the considered logics is shown to have the small model property and therefore decidable.Presented by Ewa Orlowska 相似文献

A Neuropsychological Approach to Intelligence 总被引:1,自引:0,他引:1
Ardila A 《Neuropsychology review》1999,9(3):117-136
This paper proposes that current psychometric intelligence tests are limited in evaluating cognitive activity. From a neuropsychological perspective, they fail to measure some fundamental cognitive abilities such as executive functions, memory, and visuospatial abilities. The analysis of the Wechsler Intelligence Scale presented shows that the original rationale for selecting the specific subtests included in the WAIS was unclear. The concept of a g factor in cognition is also analyzed, with the conclusion that the g factor continues to be controversial. The value of intelligence tests in predicting school performance is also criticized. It is proposed that the psychometric concept of general intelligence should be deleted from cognitive and neurological sciences. Finally, it is proposed that, in the future, neuropsychological instruments sensitive to more specific cognitive abilities replace current psychometric intelligence tests. 相似文献
