One of the most focused research programs in the science‐religion dialogue that has taken place up to the present is the series of volumes published jointly by the Vatican Observatory and the Center for Theology and the Natural Sciences. Originating with the encouragement of Pope John Paul II, this series has produced seven volumes focusing on how divine action can be understood in light of contemporary science. A retrospective volume published in 2008, Scientific Perspectives on Divine Action: Twenty Years of Challenge and Progress, contains articles reviewing the series as a whole. In this article I analyze the series as a whole as well as some of the pivotal problems discussed throughout the series, such as the zero‐sum game, scientific “traction,” falsifiability in theories of divine action, and locating special divine action in the physical world.  相似文献

Richard Foley has presented a puzzle purporting to show that all attempts in trying to find a sufficient condition of rationality are doomed. The puzzle rests on two plausible assumptions. The first is a level-connecting principle: if one rationally believes that one's belief that p is irrational, then one's belief that p is irrational. The second is a claim about a structural feature shared by all promising sufficient conditions of rationality: for any such condition, it is possible that one's belief satisfies it and yet one rationally believes that it doesn’t. With the two assumptions, Foley argues that a sufficient condition of rationality is impossible. I explain how exactly the puzzle goes and I try to offer a solution. If my solution works, all theorists of rationality who accept certain level-connecting principles need to add an extra condition to their favourite rationality-making condition.  相似文献

Trapping of interstitial (e.g. carbon) atoms is driven by the reduction in energy in the system. Diffusion of interstitials, together with their trapping in dislocation cores and/or grain boundaries, is studied by the thermodynamic extremal principle. In addition to the total Gibbs energy, a well-established formulation of the total dissipation is applied. Dimension-free evolution equations are derived, whose solution is well approximated by an easy to handle kinetic equation. Cottrell’s power law can be verified in the initial stage.  相似文献

This study compared 2- to 4-year-olds who understand how counting works (cardinal-principle-knowers) to those who do not (subset-knowers), in order to better characterize the knowledge itself. New results are that (1) Many children answer the question "how many" with the last word used in counting, despite not understanding how counting works; (2) Only children who have mastered the cardinal principle, or are just short of doing so, understand that adding objects to a set means moving forward in the numeral list whereas subtracting objects mean going backward; and finally (3) Only cardinal-principle-knowers understand that adding exactly 1 object to a set means moving forward exactly 1 word in the list, whereas subset-knowers do not understand the unit of change.  相似文献

我国现阶段的卫生财政政策及其理念分析   总被引:2,自引:0,他引:2  
系统地描述和总结了我国现行的卫生财政政策,分析了其理念,指出了其不足之处。政府应当担负起社会合作的责任,建立起卫生财政转移支付制度,在不同行政区域之间,在城市与农村之间,公平地分配公共卫生服务物品和基本医疗服务物品。以药品差价收入补偿医疗机构的卫生财政政策理念是有害的。  相似文献

Abstract :  This paper explores the role of imagination for the supervisor and examines the differences between the supervisor's use of creative and defensive imagination. It is suggested that reverie and imagining play a central role in supervision but that these need to be harnessed in the service of the reality principle. It is argued that the Jungian emphasis on the ego-self relationship provides a context for this process. A clinical example of work with a supervisee is described in which hidden aspects of a strong erotic transference/countertransference were revealed in the supervisor's imagining and became available for reflection.  相似文献

I describe characteristic phenomena of quantum physics that suggest that reality appears to us in two domains: the open and well‐known domain of empirical, material things—the realm of actuality—and a hidden and invisible domain of nonempirical, non‐material forms—the realm of potentiality. The nonempirical forms are part of physical reality because they contain the empirical possibilities of the universe and can manifest themselves in the empirical world. Two classes of nonempirical states are discussed: the superposition states of microphysical entities, which are nonempirical because observation destroys them, and the virtual states of material systems, which are nonempirical because they are empty. The non‐empirical part to physical reality represents a predetermined and hidden order that exists before it is empirical, and the visible world is an emanation out of it. I discuss consequences for our understanding of human nature, the origin of life, and human values. Reality is an indivisible wholeness that is aware of its processes, like a Cosmic Spirit, and it reveals its awareness in the mindlike properties of elementary processes as well as in the human consciousness. Thus, one is led to G. W. F. Hegel's thesis that the Cosmic Spirit is thinking in us.  相似文献

组合原则     
组合原则是逻辑语义学的基本原则,表现为函项的思想和句法与语义的对应。就构造逻辑系统而言,组合原则是一种方法论。作为延伸到自然语言形式语义学的产物,组合原则起到一种核心灵魂的作用。组合原则在理论层面和应用领域皆获得一些有价值的结果。自然语言违反组合原则的实例主要表现为歧义现象、语用因素和句法与语义不对应的情况,这正是调整组合原则的适用条件从而促进形式语义学发展的契机。  相似文献

"人造美女"热的冷思考   总被引:3,自引:1,他引:2  
"人造美女"是对美的本质的亵渎,是对女性价值全面性的否定,同时也是对医学人道主义和医学伦理基本原则的全面践踏.作为一名医务工作者,应该避免经济利益的驱动,全心全意地践行医德誓言,把治疗伤疾、维护人们的身心健康作为自己的神圣信条和基本准则.  相似文献
