神圣的简单性是中世纪哲学的难题之一,是理性服务信仰造成的。阿奎那发展了亚里士多德的哲学,论证了神是存在本身,为基督教神学建立了本体论的基础。他用神圣的简单性解释了耶稣的神性,其目的是让人更好地理解圣经内如何用理性服务信仰... 神圣的简单性是中世纪哲学的难题之一,是理性服务信仰造成的。阿奎那发展了亚里士多德的哲学,论证了神是存在本身,为基督教神学建立了本体论的基础。他用神圣的简单性解释了耶稣的神性,其目的是让人更好地理解圣经内如何用理性服务信仰。与神圣简单性具体关联的是Theos的简单性,本文论证了对Theos最适合的中文概念。 展开更多

Realism is the rational foundation for the translation of the Bible.To translate Theos in Chinese,the distinct terms神,上帝,and天主co-exist and they can be assessed by divine simplicity rationally and spiritually.One of the most difficult problems in Medieval philosophy,divine simplicity is caused by reason serving faith.Reconciling Aristotelian metaphysics with the ultimate object of faith,Aquinas defines that God is being itself and therefore he builds an ontological foundation for Christian theology and perfects divine simplicity.Related concretely with divine simplicity is the simplicity of Theos,so this paper argues that神is the best Chinese translation of Theos to reflect both the truth and the gospel. 展开更多

This paper first delivers the similarities between the notion of equivalence as propounded by Eugene Nida and that by Theo Hermans. Then the paper explains the differences of these two notions from many different aspects. To discuss both the similarities and differences, the paper aims to provide both translation workers and learners new perspectives in understanding the notion of equivalence more deeply. 展开更多

Eros and Thanatos in Theo Angelopoulos' Trilogy: The Weeping Meadow (2004) and Dust of Time (2008)

The Ancient Greek Philosophers never showed the two gods together. Nevertheless, in the main myths related to the netherworld such as those of Orpheus or Persephone, the two gods are in a continuous fight which has determined the human condition until nowadays. The author wishes in this paper to examine how the Orpheus' myth related to the duality Eros and Thanatos is treated in Theo Angelopoulos' world and especially how it appears in Ulysses' Gaze (1995) and Trilogy: The Weeping Meadow (2004) and Dust of Time (2008). In this last Angelopoulos' Trilogy, we will search the unfolds of the love story of two young people started in Odessa in 1918 and finished by the death of the woman at the end of the century, under the lens of the duality Eros and Thanatos as literal and metaphorical qualities. The historical and personal adventures of the two characters represent a daedal itinerary from East to West, which offers multiple levels of reading of the filmic texts. A comparative approach with myth, literature, and historical research will demonstrate the richness of artistic expression and a profound relationship of Angelopoulos' thought with the formulaic myths he introduces in his filmic work. 展开更多

Methods: Model of myocardial ischemia was established. Thirty five male rats were randomly divided into 5 groups, 7 rats in each group. Non ischemic group:the anterior descending branch of left coronary artery was not ligated;Ischemic group:the time of ischemia continued for 10 min;TP groups:the groups were divided into 3 subgroups, TP dose was respectively 1 mg/kg, 4 mg/kg, 16 mg/kg, TP was administered through celiac injection 20 min before the anterior descending branch of left coronary artery was ligated. Results: The levels of phosphatidylinositol 4, 5 biphosphate(PIP 2), inositol 1, 4, 5 triphosphate(IP 3)in the ischemic group were markedly higher than those in the non ischemic group. The raise of the levels of PIP 2, IP 3caused by acute myocardial ischemia were markedly inhibited by the TP. The relationship of dose effect was observed. Conclusion: TP has inhibitory effect of trans membranous signal system of acute ischemic myocardium. It has protective effect on myocardium. 展开更多
