马克思主义是实践唯物主义     

张力锋  王延光 《南京晓庄学院学报》2001,17(3):69-72

葛兰西过分夸大社会实践在马克思主义哲学体系中的地位,将其不适当地提升至本体论层次,从而形成所谓实践哲学.以马克思主义唯物一元论为背景理论框架,以经典作家的论述为依据,深入地批判葛兰西的错误认识,澄清实践、物质等基本范畴的辩证关系,对于继承和发展马克思主义哲学具有重要的理论和实践意义.  相似文献   

Seeing,hearing, reading,writing, speaking and things: on silences,senses and emotions during the “zero hour” in Germany     

Karin Priem 《Paedagogica Historica: International Journal of the History of Education》2016,52(3):286-299

This article focuses on senses, emotions and cultural practices such as writing, reading and speaking in West Germany after 1945. The period immediately following the end of the Second World War – the so-called Stunde Null, or “zero hour” – has generally been seen as a time of new beginnings, also with regard to cleansing the German language and breaking the silences of the past. This historical examination of sensory-emotional and material contexts and related cultural practices takes as its source Hanns-Josef Ortheil’s autobiographical novel Die Erfindung des Lebens (The Invention of Life), published in 2009. Ortheil’s novel is about a child’s enormous struggle to learn how to feel, see, read, write and speak. This so-called “ego document”, told by a first-person narrator, focuses on the links between things, objects, senses, emotions, and the acquisition of cultural skills and techniques while at the same time providing subtle commentary on post-war West German society.  相似文献   

Whitehead and a new look at teaching elementary science     

Robert S. Brumbaugh 《Interchange》1992,23(3):245-254

If Whitehead is right, science teachers who try to increase student interest by making the science they teach more pure and by covering more material are going about their work in just the wrong way. Science, for purposes of precision in measurement, translates the dynamic world of feeling and force, of causal efficacy (for example, the San Francisco earthquake), into a static representation spatialized and given presentational immediacy (for example, the Richter scale). But notice that the Richter scale isn't very interesting (even as abstract art) apart from its connection, via symbolic reference, to the earthquake. Such reference is essential to give both a sense of reality and a feeling of interes to the subject, but it makes the science less pure, and it takes more time to cover the material. An example of teaching pure and impure formal logic is given as a case study.  相似文献
