A simple syllogism-solving test: empirical findings and implications for g research

It has been reported that the ability to solve syllogisms is highly g-loaded. In the present study, using a self-administered shortened version of a syllogism-solving test, the BAROCO Short, we examined whether robust findings generated by previous research regarding IQ scores were also applicable to BAROCO Short scores. Five syllogism-solving problems were included in a questionnaire as part of a postal survey conducted by the Keio Twin Research Center. Data were collected from 487 pairs of twins (1021 individuals) who were Japanese junior high or high school students (ages 13–18) and from 536 mothers and 431 fathers. Four findings related to IQ were replicated: 1) The mean level increased gradually during adolescence, stayed unchanged from the 30s to the early 50s, and subsequently declined after the late 50s. 2) The scores for both children and parents were predicted by the socioeconomic status of the family. 3) The genetic effect increased, although the shared environmental effect decreased during progression from adolescence to adulthood. 4) Children's scores were genetically correlated with school achievement. These findings further substantiate the close association between syllogistic reasoning ability and g.

A survey of indian logic from the point of view of computer science

Indian logic has a long history. It somewhat covers the domains of two of the six schools (darsanas) of Indian philosophy, namely, Nyaya and Vaisesika. The generally accepted definition of Indian logic over the ages is the science which ascertains valid knowledge either by means of six senses or by means of the five members of the syllogism. In other words, perception and inference constitute the subject matter of logic. The science of logic evolved in India through three ages: the ancient, the medieval and the modern, spanning almost thirty centuries. Advances in Computer Science, in particular, in Artificial Intelligence have got researchers in these areas interested in the basic problems of language, logic and cognition in the past three decades. In the 1980s, Artificial Intelligence has evolved into knowledge-based and intelligent system design, and the knowledge base and inference engine have become standard subsystems of an intelligent system. One of the important issues in the design of such systems is knowledge acquisition from humans who are experts in a branch of learning (such as medicine or law) and transferring that knowledge to a computing system. The second important issue in such systems is the validation of the knowledge base of the system i.e. ensuring that the knowledge is complete and consistent. It is in this context that comparative study of Indian logic with recent theories of logic, language and knowledge engineering will help the computer scientist understand the deeper implications of the terms and concepts he is currently using and attempting to develop.

ΑΝΑΛΥΣΙΣ ΠΕΡΙ ΤΑ ΣΧΗΜΑΤΑ. Restoring Aristotle’s Lost Diagrams of the Syllogistic Figures

The article examines the relevance of Aristotle’s analysis that concerns the syllogistic figures. On the assumption that Aristotle’s analytics was inspired by the method of geometric analysis, we show how Aristotle used the three terms (letters), when he formulated the three syllogistic figures. So far it has not been appropriately recognized that the three terms — the major, the middle and the minor one — were viewed by Aristotle syntactically and predicatively in the form of diagrams. Many scholars have misunderstood Aristotle in that in the second and third figure the middle term is outside and that in the second figure the major term is next to the middle one, whereas in the third figure it is further from it. By means of diagrams, we have elucidated how this perfectly accords with Aristotle's planar and graphic arrangement. In the light of these diagrams, one can appropriately capture the definition of syllogism as a predicative set of terms. Irrespective of the tricky question concerning the abbreviations that Aristotle himself used with reference to these types of predication, the reconstructed figures allow us better to comprehend the reductions of syllogism to the first figure. We assume that the figures of syllogism are analogous to the figures of categorical predication, i.e., they are specific syntactic and semantic models. Aristotle demanded certain logical and methodological competence within analytics, which reflects his great commitment and contribution to the field.

Youth culture educational reform and pedagogy

The discourse of globalisation and the knowledge economy are now front and centre of the ever changing discourse of youth and youth identity. Educational reform in Malaysian society is seeking to engage the problems of globalization and the need for reform in schooling as a prerequisite for social and economic development. The education of youth is as a critical prerequisite for national advancement and development. The syllogism that structures debate with respect to globalization, youth and education is that reform to teaching technique will lead to improved competencies in students and this in turn will lead to improvements in human capital thus leading to economic and social advancement. Missing from such a simple approach is an understanding of youth culture in its multiple forms as now being productive of capacities, knowledge’s and attitudes that are arguably often far in advance of what is taught in schools. This argues that often the action in terms of cognitive growth, glocalised competencies, collaboration, cross cultural dialogue and innovative creativity are found in youth cyber communities, popular cultural movements often portrayed as problematic or troublesome. Proper educational strategies in Malaysian schooling society require teachers to learn from their students and engage innovative pedagogy not as something to be taught top down in rote fashion, but as something that is genuinely open, interactive and dialogical. This paper will discuss this theoretical issue with specific reference to Malaysian examples and policy initiatives.

Relationship between analysis and insight in Mādhyamika Buddhism (a logico-psychological model)

This thesis investigates the relationship between analysis and insight in Prasarigika Madhyamika Buddhism. More specifically it asks whether analysis is a necessary and/or a sufficient condition for the generation of insight. The thesis is divided into six chapters which include an introduction, an appendix which outlines Prasangika and Svatantrika views regarding the syllogism (svatantra) and a conclusion. The remaining chapters seek to demonstrate that analysis for the Prasarigika and the Tibetan Geluk-ba school is a necessary, but not a sufficient condition for the arising of insight. Chapter one is an investigation of certain Western psychological theories which deal with the effects on the mind of cogitating upon contradictions. Though the psychological theories are only suggestive, this chapter will lend support to the claim a) of the Prasaiigika, that analysis generates an altered state of consciousness; and b) that analysis may be a necessary and sufficient condition for the generation of insight. Chapter two seeks to construct a logico-psychological model of how insight is generated. In this model it is argued that insight is a conceptual and intuitive experience: i.e. non-inferential, and that all thought comes via the intuition. This model argues that analysis is a necessary, but not a sufficient condition for the generation of insight. In chapter three an investigation of the writings of Dzong-ka-ba (Tsong-Kha-pa) is undertaken in order to ascertain how the Tibetan Geluk-ba (dGe lugs pa) school regard the relationship between analysis and insight. The model of chapter two will be compared with the Tibetan Geluk-ba accounts to gauge its explanatory power and correspondence with the Geluk-ba views. Chapter four is an investigation of the writings of certain Western scholars. This investigation seeks to ascertain how these scholars may have regarded the relationship between analysis and insight. The chapter then compares these views with the model developed in chapter two.

Análise crítica da regra disciplinadora do não conhecimento da consulta tributária no Estado do Rio de Janeiro

Esta monografia analisa as características da consulta tributária no Estado do Rio de Janeiro, abordando suas principais características e efeitos, com enfoque na interpretação das hipóteses em que o Estado do Rio de Janeiro não conhece a consulta tributária, em especial no artigo 165, inciso III, do Decreto Estadual nº 2.473/1979. Antes de analisar como o referido dispositivo legal deve ser interpretado, foi defendido que o artigo 165 do Decreto Estadual nº 2.473/1979 foi recepcionado como lei pela Constituição Federal de 1988, com base em decisões do Supremo Tribunal Federal que entenderam (i) que uma mesma lei poderia ter dupla natureza jurídica e que (ii) um decreto anterior à Constituição Federal de 1988 foi recepcionado como lei pela atual Constituição. Além disso, foi defendido que a legislação tributária, incluindo o artigo 165, inciso III, do Decreto Estadual nº 2.473/1979, não pode ser interpretada exclusivamente de acordo com o silogismo jurídico, razão pela qual as normas jurídicas, sempre que tiverem mais de uma interpretação e/ou limitarem e/ou violarem direitos fundamentais, devem ser interpretadas de acordo com o pós-positivismo jurídico. A conclusão deste estudo é a de que o artigo 165, inciso III, do Decreto Estadual nº 2.473/1979 deve ser interpretado conforme a Constituição, de forma que a consulta tributária só não será conhecida nos casos em que a situação descrita em ato normativo for flagrantemente impossível de gerar quaisquer dúvidas sobre a interpretação da legislação tributária.

A framework to understand human action

O trabalho consiste numa análise de dois modelos explicativos do comportamento humano considerados fundamentais na literatura contemporânea sobre teoria da ação. O primeiro modelo, o causalista, tenta explicar as ações em termos de causas e leis gerais. O segundo explica a ação em termos de intenções e silogismos práticos. As dificuldades e problemas de ambos modelos são apresentadas e na última parte do ensaio propomos um modelo alternativo baseado na noção de retrodução.

Savitri y Orfeo : La argumentación en la lógica india y en la retórica clásica

Los mitos de Savitri (Mahabharata 3.293-299) y Orfeo (Ovidio. Metamorfosis 10.1-85), pertenecientes al ámbito cultural indoeur opeo, presentan algunos puntos en común: narran la historia del amante que rescata a su ser amado de la muerte, y combinan el encuentro con los dioses de la muerte y el discurso mediante el poder de la palabra. En esta propuesta, se analizan los discursos de los protagonistas a partir de las convenciones propias de cada contexto de enunciación. Para el caso indio, se sigue el modelo lógico de la escuela Nyaya; para el greco-latino, el de la retórica clásica. De este modo, sobre la base de la estructura argumentativa del silogismo aristotélico, se plantean dos variaciones, respectivamente, el silogismo hindú y el silogismo retórico. Se trata de dos aproximaciones argumentativas con métodos distintos pero con un mismo fin: (con)vencer al oponente
