社会实践发展的动力是什么 ?这是马克思主义社会实践观的一个基本问题 ,但至今很少有人对此进行专题研究。本文作者对此发表了自己的看法 :社会实践发展的动力是由多种因素多个层次有机结构起来的复杂系统。一、人的日益增长的需要和利益是社会实践发展的原动力。二、主体与客体之间、主体与中介之间、中介与客体之间、目的和结果之间的矛盾是社会实践发展的普遍性内在动力。三、各类型具体社会实践各有其特殊性内在动力。四、各类型具体社会实践之间相互作用、相互影响、相互促进 ,每一具体社会实践的发展都可以成为其他社会实践发展的外部动力 ,每一具体社会实践的发展又有其他社会实践发展为它的外部动力。作者对这几个观点作了较为详细的论述。本文最后指出 ,“社会实践发展的动力”问题在一定意义上说比“实践是检验真理的唯一标准”问题更重要 ,希望有更多的哲学工作者对此进行系统深入的研究 What is the driving force behind the development of social practice? This is a basic issue of the Marxist view of social practice, but so far, few have conducted any special studies on it. The author of this article has expressed his own view: the driving force for the development of social practice is a complex system composed of multiple levels of organic structure with a variety of factors. First, the growing needs and interests of people are the driving force behind the development of social practice. Second, the contradiction between the subject and the object, between the subject and the agent, between the agent and the object, between the object and the result is the universal internal motivation for the development of social practice. Third, each type of specific social practice has its own intrinsic motivation. Fourth, the interaction between various types of specific social practices, mutual influence, mutual promotion, the development of each specific social practice can become the external motivation for the development of other social practice, the development of each specific social practice and other social practices for the development of It’s external power. The author made a more detailed discussion of these views. Finally, the paper points out that “motivation for the development of social practice” is more important than “practice is the sole criterion for testing truth” in a certain sense and hopes more and more philosophers will conduct a systematic and in-depth study on this issue
