Chemical supervenience

This paper surveys some ways in which the chemical realm can be described and outlined in terms of the concept of supervenience. The particular contours of general chemical theory provide a ready basis for interpretation of determination, covariance, and nonreduction—the characteristic metaphysical facets of the supervenience relation—in mutual terms. Building on this, the extent to which chemically characterized properties and entities can be described in terms of a supervenience-scaffolded structure represents a particularly vivid application that philosophers in general interested in supervenience would do well to attend to. In addition, the model of chemical supervenience given here can be used as a rubric on which to decide on issues already raised by philosophers of chemistry.

亚里士多德的时间观念研究

在物理认识史上，亚里士多德对时间和空间的基本属性作了前所未有的系统研究，建立了人类历史上第一个比较完整的时间空间理论体系，亚里士多德的时空学说对古代及近代物理学和哲学的发展都产生了重要而深远的影响。文章系统探讨了亚里士多德关于时间的学说，从中归纳出一系列结论性的认识，由此集中展示了他关于时间认识的基本成果，并简单讨论了这些成果对现代物理学认识的启发意义。
