中小学教师知识观与教学观研究

本文就中小学教师对于知识和教学的基本观点以及它们之间的相互关系进行了初步探讨,结果表明：教师们普遍认识到知识是相对的、辩证的和有联系的,认为教学不是知识的简单地灌输而是帮助学生完成意义的建构。教师在知识观的“机械-辩证”和教学观的“接收-建构”两个维度之间存在显著的正相关．     

Structural Realism, Scientific Change, and Partial Structures

Scientific change has two important dimensions: conceptual change and structural change. In this paper, I argue that the existence of conceptual change brings serious difficulties for scientific realism, and the existence of structural change makes structural realism look quite implausible. I then sketch an alternative account of scientific change, in terms of partial structures, that accommodates both conceptual and structural changes. The proposal, however, is not realist, and supports a structuralist version of van Fraassen’s constructive empiricism (structural empiricism).     

Combining Possibilities and Negations

Combining non-classical (or sub-classical) logics is not easy, but it is very interesting. In this paper, we combine nonclassical logics of negation and possibility (in the presence of conjunction and disjunction), and then we combine the resulting systems with intuitionistic logic. We will find that Kracht's results on the undecidability of classical modal logics generalise to a non-classical setting. We will also see conditions under which intuitionistic logic can be combined with a non-intuitionistic negation without corrupting the intuitionistic fragment of the logic.

WHAT MAKES A QUANTUM PHYSICS BELIEF BELIEVABLE? MANY-WORLDS AMONG SIX IMPOSSIBLE THINGS BEFORE BREAKFAST

An extraordinary, if circumscribed, positive shift has occurred since the mid-twentieth century in the perceived status of Hugh Everett III's 1956 theory of the universal wave function of quantum mechanics, now widely called the Many-Worlds Interpretation (MWI). Everett's starkly new interpretation denied the existence of a separate classical realm, contending that the experimental data can be seen as presenting a state vector for the whole universe. Since there is no state vector collapse, reality as a whole is strictly deterministic. Explained jointly by the dynamical variables and the state vector, “this reality is not the reality we customarily think of, but is a reality composed of many worlds,” wrote Everett's colleague Bryce DeWitt. In this essay, I account briefly for the change of status in conventional scientific terms, yet chiefly in extended terms of three sets of ideas that I argue can be understood to affect believability in both scientific and religious contexts, illuminating helpfully the MWI phenomenon, and its engagement with theology: orthodoxy and heresy, language and reference, and faith and agnosticism. One's orientation relative to the variable content of these dynamic, socially oriented categories helps to make belief in ideas as metaphysically challenging as Everettian Quantum Mechanics, or particular ideas about God, either more or less believable. The categories will have the same function in a theology engaging Everett's theory, and in any theology at all written in a society deeply marked by what I further argue is a subtle, powerful, and pervasive mode of quasi-scientific thinking we can call societal constructive agnosticism, of which anyone doing theology today must be aware.     

Schopenhauer on Christ,Suffering and the Negation of the Will

ABSTRACT

This paper seeks to illuminate Schopenhauer’s notion of the negation or denial of the will by investigating the figure of the saint within his philosophy. We argue that various discussions in Schopenhauer’s works of the possible role of Christ as exemplar reveals an underlying Christological understanding of self-denial as a model for the saint. The connection between Schopenhauer’s approach to Christ and Kant’s Christology in Religion within the Bounds of Mere Reason is also explored. We note how Schopenhauer builds on the Kantian demythologization of the Incarnated Christ in order to uncover the moral and existential spirit that underlies Christianity. In addition, we outline how a recognition of the symbolic importance of Christ for Schopenhauer suggests features of the denial of the will that have been overlooked in the literature, involving the intellectual transcendence of suffering through the cultivation of a state of emotional unresponsiveness. It is argued that this reflects a deeper connection between Schopenhauer’s philosophy and Christian thought than is often recognised.
