海德格尔认为"美"源自审美状态,而审美状态并非是主体的某种精神状态,而是"存在"的本然状态。美是存在者自身的显现,"存在"即是美的本质,也是美的功用,美不是显现的结果,而是"显一现"这个动态过程。存在之显现之所以美是因为,人无法在流变的世界中领会与观照存在之本质,存在必然在生活的日常状态中被遗忘,只有打破了这种遗忘状态,人才能获得真正的自由,获得存在之澄明,这种获得存在之澄明状态过程,就是获得美的本质与本源的过程,美就是存在者的澄明之光,是存在之光。  相似文献

文明是决定和影响人类活动的长期的基本因素。冷战结束后,特别是随着“文明冲突论”的提出,各种文明观的讨论逐渐演化成文明学的各种派系。当前主要有三种文明观:文明冲突论、文明对话论、文明交往论。在处理国与国关系的实践中应承认并维护文明的多样性。文明发展的趋势是文明和谐和文明相处。人类真正的危险在于各个民族、国家间文明的互不相融,以及由此导致的误解、紧张、冲突乃至战争。世界的持久和平与持续发展有赖于人与人之间、民族与民族之间、国家与国家之间文明的对话、沟通和理解,有赖于文明间的和谐,共同发展。  相似文献

论老子哲学的“无”   总被引:1,自引:0,他引:1  
老子对其“道”有着一以贯之的思路,即道是对生命本真存在的体悟。“无”在老子道论中具有核心地位,“无”是道的超验性的指称。因此,道之“生”,并非宇宙论的化生,而是出于生命的体验,其本质就在于“无”之生,是“无”之心体对万物的当下成就。以“无”为本体的“无—有”一体化运作形成道的内在结构,“无”在“言”出“有”中踏入了超验性与经验性的两难境地,而“有”对“无”的当下回归使物我保其真性。在这个结构中,“真”是“无”的内涵,“虚”与“静”构成了“无”的动力机制。  相似文献

黑格尔认为,理性即正义。现实的正义不过是理性的正义的自我实现,正义的现实性存在于正义的必然性之中,人类正义的发展历程决不是田园诗般令人快意的,人民群众只是理性和正义自我实现的工具。黑格尔看不到人民群众在正义的实现中的主体作用。  相似文献

弗洛伊德坚持“性欲乃是人类取得的一切成就的源泉”,认为“本能的升华是最引人注目的文化发展的特征;正是由于升华,高级的心智活动、科学活动、艺术活动或思想活动才成为可能。”人们对此很有异议。其实,弗洛伊德是在对“性”的最广泛意义的理解基础上创建他的“动力心理学”的,他试图从他对人的个体心理理解的立场出发,来解释人类的全部历史、全部事件和社会生活的结构,并以此建立一整套关于人类精神生活规律的学说和理论。深入探寻弗洛伊德性学说的底蕴,澄清他的“性力”、“原欲”概念的内涵,真正领悟其“升华”思想的真谛,才有可能拓宽我们的视野,深化对复杂纷繁的人的精神世界的研究。  相似文献

Students have to be punished if they have made a serious transgression. Avoidance of punishment will lead to serious complications. But punishment is inseparably linked with guilt and forgiveness. The inability of individuals to forgive themselves was regarded by Kierkegaard to be an emanation of individual false pride, a kind of vanity. This type of despair, a psychological and spiritual disorder, is a serious and debilitating problem. The inability to escape this despair of forgiveness can lead to a loss of genuine humanness. Unchecked, this despair can lead to unrelatedness of self to itself and fear of the possibility of freedom. Thus the self-knowledge attainable in despair over the forgiveness of an offense would lead to what we would call a successful rehabilitation of the individual and his or her conjunct reintegration into society. Kierkegaard's ideas on punishment are interesting — historically and philosophically speaking — because they represent a softening of a harsh view of punishment by stressing the humanizing aspects of guilt and forgiveness.  相似文献

个性观念是陈独秀、李大钊、胡适等五四主流思想家的主导话语 ,是一个重要的现代性观念。可以从消极和积极两个维度理解五四时期的个性观。消极个性指对宗法性和奴隶性的反抗 ,积极个性与认识论上的理性主义、伦理学上的功利主义等有密切关联。五四时期的个性观从一个侧面反映现代性意识的发育历程。五四主流思想家注意到消极个性与积极个性的多重内涵与意义 ,表明中国知识分子对现代性理解的深化。同时 ,个性观上的局限也表明中国现代性意识发展的曲折性与困难性  相似文献

This paper discusses the current radical changes in the Australian education policy. Central to the argument is the claim that the radical restructuring of the public sector hastened the loss of the possibility of any critical evaluation of national policy.The paper argues that this shift has been forced on the Australian state by the objective conditions expressed in a new realignment of the dominant transnational capital with the subordinate domestic capital, and in the shifts in a global capacity for consumption. The argument is underpinned by the claim that a new, post-Fordist (or flexible specialization) regime of capital accumulation is at present replacing the Fordist regime of mass production and consumption.The paper further argues that in order to achieve the system-preferred changes in the Australian education policy, the Australian government introduced radical changes in the production rules of policy formation. This involved a narrowing of policy making context and, crucially, an exclusion of voices critical of the shift towards economic reductionism.This loss of a critical sensibility constitutes the central concern of this paper. To advance the argument, in Part One, the paper discusses the relationship between the Australian state and the post-Fordist objective conditions of capital accumulation. Part Two argues that the lack of intellectual tradition in Australian public life was at least partially responsible for the easy passage given to neoclassical economics1 perspective in becoming a dominant public policy paradigm. Part Three locates the role of education within the context of the European philosophical tradition. It provides the link between critical sensibility, the project of Western civilization (which clearly extends beyond the modern vs. postmodern dichotomy), and the role of public discourse. Finally, the paper argues that education policy needs to take the issue of critical sensibility seriously. For this reason, it needs to be informed by a desire to go beyond the mere technical fit between graduates and the workplace, and allow itself to be inspired by new ideas, and new ways of seeing.Parts One and Two of this Article appeared in INTERCHANGE, Vol. 26, #2, 1995.  相似文献
