以象解筮的探索——论尚秉和先生对《左传》《国语》筮例的阐解

《左传》《国语》中的筮例,是对《易》学研究极具价值的材料,历代学者对此进行过许多研究考辨、阐释解说。近代《易》学大师尚秉和先生既以《左传》《国语》筮例作为创立“尚氏学”的最重要的佐证材料之一,又将“以象解《易》”的方法用以阐解《左传》《国语》的筮例,颇具特色。本文考察了尚先生以象解筮的具体内容,辨析了“尚氏说”的自洽性,并就“尚氏说”中“观象”与“用象”、“易理”与“义理”等问题进行追问与思考。     

释《周易·渐卦》

通过对渐卦卦象的分析,并考《说文》段注“陂陀曰渐”,得出渐卦取名为渐,当取坡渐之意,进而引伸为渐进之意。又从卦爻象出发,对渐卦的卦爻辞作出分析,认为渐卦的卦爻辞是根据其卦爻象而系出,而且其整卦的卦爻辞都是围绕着一个中心主题而展开,且其思想与《诗经》中的《鸿雁》等篇不无关系。这或可为进一步解读《周易》古经及其产生时代问题提供某种有益的启示。     

《易传》"立象以尽意"思想发微

“言”、“象”、“意”之间的关系问题,是易学研究中一个至关重要的问题。以老庄道家“言不尽意”论立论,《易传》作者不仅第一次明确提出了“言不尽意”的命题,而且首创“立象以尽意”之说,不仅实现了《周易》由卜筮之书到哲学之书的整体转换,而且完成了儒道言意思想的创造性整合,从而确立了其在中国思想文化史上至为重要的地位。至于“象”能否尽“意”,《易传》作者并没有说。没有说并不等于没有问题。而这个问题在其后的提出和讨论,则不仅直接引发了魏晋玄学的“言意之辨”,实现了两汉经学向魏晋玄学的转换和玄学本体论哲学的理论建构,而且通过玄学“言意之辨”,即按照“言不尽意”和“得意忘言”的理论和方法,不仅为佛教的中国化和宋明理学的综合创新开辟了广阔的道路,同时也为以“意象”为核心的中国审美文化的繁荣和发展奠定了坚实的思想理论基础,而这也正是《易传》“立象以尽意”思想的意义和价值所在。     

“易”的世界观和思维模式

本文认为,《周易》的阴阳世界观注重的是阴阳间的关系,而这种关系又有两个重要状态,一个是“空无”,另一个是“中庸”。对于这两种状态的不同态度形成了古人不同的人生态度和理想追求。同时,本文还认为,《周易》所运用的是取象比类式的象数推演体系,它不同于概念式的演绎体系。人类生活有很多重要内容不能通过概念式的语言去思维和表达,而这些“不可言说”的内容却往往可以用“象征语言”和象数思维来表达。     

易学思想与中国传统建筑

本文从卦象、易数与阴阳合德三方面论述了易学思想与中国传统建筑之间不可分割的联系,中国建筑作为中华文明的重要组成部分,其本源是来自<周易>,与易学思想的发展变化密切相关.     

Music in dreams and the emergence of the self

Abstract :  This paper deals with the presence and possible 'meaning' of music in dreams. The author explores a possible meaning of music as the most fundamental human symbolic experience, which directly points to the emergence of the Self from the primal union mystique with the Great Mother. The relationships between acoustic and visual experiences are taken into account as two basic human forms of coming into existence, although wholly different from each other. The role of music in dreams seems to be that of the most direct representation of the emerging Self in its pure, pre-representational form. Therefore, when music appears in dreams, providing there is the activation of an emotional tone, all other elements—visual and verbal—should be considered as the expression of the sense to which the music is pointing. A clinical example is described in order to better express the author's opinions.     

不同特质焦虑水平的选择性注意偏向

高特质焦虑个体常表现出对威胁性刺激的选择性注意偏向的特点。然而其潜在的神经机制目前仍不清楚。通过记录高、低特质焦虑者各17名进行情绪加工时的ERP,比较了两组个体在选择性注意偏向发生的时间进程和相关的神经反应的差异。结果发现,高特质焦虑者诱发出更大的N1,进一步发现恐惧图片比中性图片诱发更大的N1;而低特质焦虑者诱发了更大的N2,特质焦虑得分越低, N2波幅越大。结果初步说明高特质焦虑者加工早期对恐惧图片分配了较多的注意资源,并且其抑制执行功能可能受损;而低特质焦虑者较晚开始区分恐惧图片和中性图片。这些结果提供了支持认知-动机模型的新证据。     

Object-centered representations support flexible exogenous visual attention across translation and reflection

Visual attention can be deployed to stimuli based on our willful, top-down goal (endogenous attention) or on their intrinsic saliency against the background (exogenous attention). Flexibility is thought to be a hallmark of endogenous attention, whereas decades of research show that exogenous attention is attracted to the retinotopic locations of the salient stimuli. However, to the extent that salient stimuli in the natural environment usually form specific spatial relations with the surrounding context and are dynamic, exogenous attention, to be adaptive, should embrace these structural regularities. Here we test a non-retinotopic, object-centered mechanism in exogenous attention, in which exogenous attention is dynamically attracted to a relative, object-centered location. Using a moving frame configuration, we presented two frames in succession, forming either apparent translational motion or in mirror reflection, with a completely uninformative, transient cue presented at one of the item locations in the first frame. Despite that the cue is presented in a spatially separate frame, in both translation and mirror reflection, behavioralperformance in visual search is enhanced when the target in the second frame appears at the same relative location as the cue location than at other locations. These results provide unambiguous evidence for non-retinotopic exogenous attention and further reveal an object-centered mechanism supporting flexible exogenous attention. Moreover, attentional generalization across mirror reflection may constitute an attentional correlate of perceptual generalization across lateral mirror images, supporting an adaptive, functional account of mirror images confusion.
