Philosophers on drugs

Synthese - There are some philosophical questions that can be answered without attention to the social context in which evidence is produced and distributed. Abstracting away from social context is...     

一所培养哲学家的学校——牛津的哲学教育

本文把牛津等英国大学做哲学的方式与德国所谓的哲学研究进行比较,并论证:由于英国现存的一系列特殊的教育体制,使得德国所流行的那些做法不可能在英国得到鼓励.譬如,牛津大学实行导学制,对学生做每周至少一次耳提面命式的指导;校方对教学很重视,把教学而不是写作作为教师的主要职责;教师的职位很有保障,只要完成教学任务,对发表作品不做什么要求;写作和发表作品是研究兴趣、自我激励和思想成熟的自然后果;如此等等.总之,在英国大学,哲学师生之间、同事之间共享的不是一组哲学信条,而是一套学术标准.与其说牛津大学是一所传播哲学知识的学校,不如说是一所培养哲学家的学校.     

Superselection Rules for Philosophers

The overaraching goal of this paper is to elucidate the nature of superselection rules in a manner that is accessible to philosophers of science and that brings out the connections between superselection and some of the most fundamental interpretational issues in quantum physics. The formalism of von Neumann algebras is used to characterize three different senses of superselection rules (dubbed, weak, strong, and very strong) and to provide useful necessary and sufficient conditions for each sense. It is then shown how the Haag–Kastler algebraic approach to quantum physics holds the promise of a uniform and comprehensive account of the origin of superselection rules. Some of the challenges that must be met before this promise can be kept are discussed. The focus then turns to the role of superselection rules in solutions to the measurement problem and the emergence of classical properties. It is claimed that the role for “hard” superselection rules is limited, but “soft” (a.k.a. environmental) superselection rules or N. P. Landsman’s situational superselection rules may have a major role to play. Finally, an assessment is given of the recently revived attempts to deconstruct superselection rules.

The simpler syntax hypothesis

What roles do syntax and semantics have in the grammar of a language? What are the consequences of these roles for syntactic structure, and why does it matter? We sketch the Simpler Syntax Hypothesis, which holds that much of the explanatory role attributed to syntax in contemporary linguistics is properly the responsibility of semantics. This rebalancing permits broader coverage of empirical linguistic phenomena and promises a tighter integration of linguistic theory into the cognitive scientific enterprise. We suggest that the general perspective of the Simpler Syntax Hypothesis is well suited to approaching language processing and language evolution, and to computational applications that draw upon linguistic insights.     

Infants prefer higher-pitched singing

Female singers were recorded singing a song in a high and/or a low range. Infants preferred to listen to the higher-pitched versions, suggesting that infants' preference for infant-directed singing and speech is mediated in part by a preference for higher pitch.     

Philosophers on the "Art-of-Living"

Art-of-living is a classical notion in philosophy that is currently receiving renewed interest. Art-of-living refers to a kind of self-direction with a view to the good life. This paper surveys modern philosophical thought on this subject. This revised version was published online in August 2006 with corrections to the Cover Date.     

Mary and the Vocation of Philosophers

Pope John Paul II, in Fides et ratio #108, states that there is a deep harmony between the vocation of true philosophy and the Blessed Virgin Mary. This intriguing claim, so different from the usual link of Mary with faith, is developed in this article. Drawing analogical implications from selected events in Mary's life, two questions will be asked: How do philosophers "philosophize in Mary?;" and how could this way of philosophizing help us today to renew the vocation to be a philosopher? The following authors are considered: Thomas Aquinas, Edith Stein, Jacques and Raïssa Maritain, Bernard Lonergan, Josef Ratzinger, Mary Daly, Robert Sokolowski, Norris Clarke, Søren Kierkegaard, Karol Wojtyla, John Paul Sartre, Simone de Beauvoir, Judy Chicago, and John Henry Newman.     

Humans prefer curved visual objects

People constantly make snap judgments about objects encountered in the environment. Such rapid judgments must be based on the physical properties of the targets, but the nature of these properties is yet unknown. We hypothesized that sharp transitions in contour might convey a sense of threat, and therefore trigger a negative bias. Our results were consistent with this hypothesis. The type of contour a visual object possesses--whether the contour is sharp angled or curved--has a critical influence on people's attitude toward that object.
