A new English translation, with commentary, of the treatise On Issues by Hermogenes of Tarsus. The book is intended to make sophisticated theories of argument developed by Greek teachers of rhetoric in the second century AD accessible both to specialist and non-specialist readers. Of interest to scholars of all types of Greek literature.

Explore the seminal Platform Sutra, with one of the greatest living Zen masters as a guide. A lodestone of Zen Buddhism, the Platform Sutra presents the life, work, and wisdom of Eno, or Huineng, the fascinating and much-loved seventh-century Sixth Patriarch of Chinese Zen. An illiterate woodcutter who famously attained enlightenment after only hearing a single line of a sutra, and who went on to decisively upstage senior monks with a poem that demonstrated the depth and clarity of his insight, (...) his example has demonstrated to generations of students and spiritual seekers worldwide that enlightenment is attainable regardless of education or social standing. His exhortations to directly perceive one's true nature, right here and now, still reverberate in contemporary Zen. There is no bodhi tree, Nor stand of a mirror bright. Since all is void, Where can the dust alight? Shodo Harada Roshi's fresh reading of the Platform Sutra offers both the history behind the work and the lived experience of its wisdom. In a plain-English, conversational voice, Shodo Harada brings the sutra to life for his students, discussing and explaining its central points chapter by chapter and illustrating it with his own beautiful calligraphy. This is far from a collection of dry lectures; it is an essential Buddhist text brought to life. (shrink)

From a sociological and gender perspective, this research investigated the model of masculinity characteristic among profeminist men compared to that of the general population of men, based on a comparison of ideas, attitudes and social praxis. The results show a clear tendency in the first group towards greater egalitarianism in all parameters in comparison to the traditional model of masculinity. As regards the potential for change, the difference in attitudes was especially marked, with the concomitant and well-known effect on praxis (...) in the use of time. This can be said to represent a model of masculinity still in the process of development, but heading in the right direction. (shrink)

This study examined the effects of mood and risk-taking on divergent and convergent thinking using a Q-learning computation model. The results revealed that while mood was not significantly related to divergent or convergent thinking (as creative thinking types), risk-taking exerted positive effects on divergent thinking in the face of negative rewards. The results were consistent with the representational change theory in insight problem solving. Although this theory accounts directly for insight, the underlying idea of going beyond current contexts and implicit (...) constrains could be applied to creative thinking as well. The results indeed accounted for the relevance of this theory to divergent thinking. The current study is one of the first empirical studies simultaneously examining the role of mood and risk-taking in creativity. In particular, no related studies exist that took a computational approach to estimate the relevant parameters in the framework of dynamic optimization. Our Q learning model enables to distinguish and identify the different roles of mood and risk-taking in updatingQvalues and making decisions. (shrink)

O objetivo deste texto é discutir a tarefa filosófica de elucidação do conceito de conseqüência lógica. Primeiramente, serão eleitos dois critérios de adequação para uma elucidação desse conceito: (1) preservação da verdade nas instâncias, ou adequação material e (2) garantia da verdade da conclusão na inferência válida, ou adequação epistêmica. Em seguida serão apresentadas a proposta de Tarski (1956) e as correspondentes críticas de Etchemendy (2008). Conclui-se com comentários a respeito da natureza das investigações lógicas.

I show that propositional intuitionistic logic is complete with respect to an adaptation of Dummett’s pragmatist justification procedure. In particular, given a pragmatist justification of an argument, I show how to obtain a natural deduction derivation of the conclusion of the argument from, at most, the same assumptions.

Dummett’s justification procedures are revisited. They are used as background for the discussion of some conceptual and technical issues in proof-theoretic semantics, especially the role played by assumptions in proof-theoretic definitions of validity.

Philosophical inquiries into the nature of consciousness have long been intrinsically tied to questions regarding the nature of the self. Although philosophers of mind seldom make reference to the role of cultural context in shaping consciousness, since antiquity culture has played a notable role in philosophical conceptions of the self. Western philosophers, from Plato to Locke, have emphasized an individualistic view of the self that is autonomous and consistent across situations, while Eastern philosophers, such as Lao Tzu and Confucius, have (...) argued for a collectivistic view of the self, one that is interconnected to others and embedded within specific social contexts and situations. Here we argue that a comprehensive theory of consciousness needs to account for the role of cultural context and its bidirectional interaction with neural and genetic mechanisms in shaping a variety of conscious phenomena, from visual perception to self- awareness. We review recent evidence of cultural variation in neurobiological mechanisms underlying these phenomena and discuss the implications of these cultural neuroscience findings for the study of consciousness.

The dissertation provides an analysis and elaboration of Michael Dummett's proof-theoretic notions of validity. Dummett's notions of validity are contrasted with standard proof-theoretic notions and formally evaluated with respect to their adequacy to propositional intuitionistic logic.

During 1980–90, Japan's annual real GDP growth rate was 4.6%, but which declined to 1.2% in the 1990s. While the drop in itself is a problem, at the same time it exacerbated many other problems, namely inequality, budget deficits, and the increasing burden of an aging society.

Minamata disease was first officially recognized in May 1956. Its earliest victims were small children. Environmental contamination most rapidly and seriously affected the physiologically weak among the residents. However, the outbreak of the disease in humans was preceded by abnormalities in the natural environment such as massive death of fish and shellfish, and the abnormal behavior and death of cats. It used to be considered that poisoning was caused by direct exposure to a toxic substance, and that toxic substances did (...) not pass the placenta. Minamata disease is an indirect poisoning by methyl mercury through the food chain as a result of environmental contamination, and is the first known disease to cause abnomalities in the fetus due to a toxic agent passing through the placenta. Minamata disease, therefore, had implications in various fields. Namely it also stirred up legal, ethical, and eugenic arguments concerning fetal protection. This report reviews the course of Minamata disease, and evaluates its impacts. “Minamata Studies” has three intellectual and scientific missions to change the social systems that caused the disease; to pursue environmental justice; and to explore the possibility of an environment that permits coexistence not only of all humans, but of all living things.

This paper establishes a new impossibility result for welfaristic evaluations when the population varies. We consider a weak version of the repugnant conclusion instead of the commonly used version. It is shown that if a population principle satisfying two reasonable properties avoids the sadistic conclusion, then the weak repugnant conclusion must hold. We use a general variable-population setting where the identities of individuals can matter.

Mental imagery of movement is a potentially valuable rehabilitation task, but its therapeutic efficacy may depend on the specific cognitive strategy employed. Individuals use two main strategies to perform the hand mental rotation task, which involves determining whether a visual image depicts a left or right hand. One is the motor imagery strategy, which involves mentally simulating one’s own hand movements. In this case, task performance as measured by response time is subject to a medial–lateral effect wherein the RT is (...) reduced when the fingertips are directed medially, presumably as the actual motion would be easier. The other strategy is to employ visual imagery, which involves mentally rotating the picture and is not subject to this medial–lateral effect. The rehabilitative benefits of the HMRT are thought to depend on the MI strategy, so it is essential to examine the effects of individual factors such as age, image perspective, and innate ability on the strategy adopted. When presented with pictures of the palm, all subjects in the current study used the MI strategy, regardless of age and ability. In contrast, when subjects were presented with pictures of the back of the hand, the VI strategy predominated among the young age group regardless of performance, while the strategy used by middle-age and elderly groups depended on performance ability. In the middle-age and elderly groups, the VI approach predominated in those with high performance skill, whereas the MI strategy predominated among those with low performance skill. Thus, higher-skill middle-aged and elderly individuals may not necessarily form a motion image during the HMRT, potentially limiting rehabilitation efficacy. (shrink)

We examine the proof-theoretic verificationist justification procedure proposed by Dummett. After some scrutiny, two distinct interpretations with respect to bases are advanced: the independent and the dependent interpretation. We argue that both are unacceptable as a semantics for propositional intuitionistic logic.
