Avicenna's Conception of the Efficient Cause

The concept of efficient causation originates with Aristotle, who states that the types of cause include ‘the primary source of the change or rest’. For Medieval Aristotelians, the scope of efficient causality includes creative acts. The Islamic philosopher Avicenna is an important contributor to this conceptual change. In his Metaphysics, Avicenna defines the efficient cause or agent as that which gives being to something distinct from itself. As previous studies of Avicenna's ‘metaphysical’ conception of the efficient cause attest, it takes God as a model agent. This essay considers whether Avicenna's ‘metaphysical’ conception of the efficient cause applies to natural agents. It ultimately argues that Avicenna offers a unified view of the efficient cause, which includes both divine and natural agents. On this view, an efficient cause gives being to another and is simultaneous with its effect. While Avicenna's defence of this view is an important chapter in the history of the concept of the efficient cause, it is also of interest in its own right. By appeal to a version of the principle of sufficient reason, it challenges a widespread view that causes are temporally prior to their effects.

血液透析患者在线血流量与Kt／V及尿素清除率因果关系分析

通过测定维持性透析患者血管通路血流量、Kt/V及尿素清除率(URR),利用自然辨证法中因果关系的复杂性探讨血流量与透析充分性之间的因果关系。选择维持性血液透析患者80例。设定血液透析开始后在线血流量,根据血流量不同分为三组,I组血流量300ml/min,Ⅱ组血流量250ml/min,Ⅲ组血流量200ml/min,计算各组Kt/V值与尿素减少率,观察血流量与Kt/V及尿素减少率之间的相关关系。三组之间Kt/V、URR比较P<0.001,差异均具有显著性;血流量与Kt/V、URR之间呈正相关(r1=0.448,P<0.001;r2=0.413,P<0.001;)随着血流量从300ml/min降到200ml/min,Kt/V、URR分别从1.33±0.33、(68.19±8.86)%降到0.99±0.31、(58.59±13.19)%。血液透析患者的血流量与Kt/V、URR密切相关,两者之间存在因果关系,较高的在线血流量是保证透析充分性的一项重要指标。     

评价和控制药物不良反应的认识与思考

用科学的世界观和方法论指导药物不良反应的评价和控制。从药物不良反应的发生机制、临床表现、因果关系的判定原则出发,与马克思主义哲学的基本观点相结合,提出了几点认识和思考。药物治疗作用与副作用既对立又统一;药物治疗效应向毒性反应的转变是量变到质变的过程;药物过敏反应的发生是内因外因相互作用的结果;药物与不良反应联系强度的判定必须符合前因后果性;药物与不良反应联系强度的判定必须排除混杂因素的干扰,找到内在的、本质的联系。     

术后认知功能障碍病因探索的反思

术后认知功能障碍(POCD)是手术后的一个并发症,随着接受手术治疗的患者越来越多,这一并发症引起了医学家们的广泛关注。但到目前为止,其发病的原因和机制尚不清楚。通过查找总结国内外学者对术后认知功能障碍病因的研究过程,我们发现其中无不渗透着哲学的思想。     

THE EXISTENCE OF GOD AND THE CREATION OF THE UNIVERSE

Abstract. Kant argues that any argument for a transcendent God presupposes the logically flawed ontological argument. The teleological argument cannot satisfy the demands of reason for a complete explanation of the meaning and purpose of our universe without support from the cosmological argument. I avoid the assumption of a perfect being, and hence the ontological argument, in my version of the cosmological argument. The necessary being can be identified with the creator of the universe by adding analogical mental relations. The creation of the universe is then shown to reflect modern scientific cosmology as well as stories and metaphors in the Eastern and Western religious traditions and to resolve the problem of evil.     

Robert Boyle and the Machine Metaphor

The seventeenth–century chemist and philosopher Robert Boyle argued that the world is like a clockwork machine. This led to the problems of the place of a Creator and of how one can explain the directed, "final–cause" nature of organisms. Boyle thought that he could wrap everything up in one neat package, with a clear place for a designing God, but of course the coming of Darwinism casts doubt on this. Nevertheless, Boyle's thinking does have some very interesting implications for the way in which we today should consider the science/religion relationship.     

Separate- versus <Emphasis Type="Italic">common</Emphasis>-common-cause-type derivations of the Bell inequalities

Standard derivations of the Bell inequalities assume a common-common-cause-system that is a common screener-off for all correlations and some additional assumptions concerning locality and no-conspiracy. In a recent paper (Graßhoff et al., The British Journal for the Philosophy of Science, 56, 663–680 (2005)) Bell inequalities have been derived via separate common causes assuming perfect correlations between the events. In the paper it will be shown that the assumptions of this separate-common-cause-type derivation of the Bell inequalities in the case of perfect correlations can be reduced to the assumptions of a common-common-cause-system-type derivation. However, in the case of non-perfect correlations a non-reducible separate-common-cause-type derivation of some Bell-like inequalities can be given. The violation of these Bell-like inequalities proves Szabó’s (International Journal of Theoretical Physics, 39, 911 (2004)) conjecture concerning the non-existence of a local, non-conspiratorial, separate-common-cause-model for a δ-neighborhood of perfect EPR correlations.     

傣医学因果联系观初探

傣医学的哲学基础多源于佛教哲学,其因果联系观就是基于佛教的缘起论观点建立起来的。傣医将此观点广泛用于对人体生命的认识,用以解释生命的产生,解释生理、病理,用于病因学及指导诊断、用药,还用于指导养生,是傣医学重要组成部分。
