导言 我们经常对一时、一地的实践进行推广和普及,也常根据过去的经验来引导未来的规划。如此将一些琐碎、个别的直接经验提纲挈领地归纳起来,就可以避免让我们一次又一次退回到零的起点。在适应性行为和社会交流的发展过程中,进行这种零散经验的联系和积累是十分必要的。“理论”一词的涵义理应包括“经验的分析和总结”,唯其如此,它才能真正成为指导我们实践生活须臾不可或缺的舵手。 Introduction We often promote and popularize one-time and one-place practices and often guide future plans based on past experience. In this way, some trivial and individual direct experience syllabuses can be summed up to prevent us from returning to zero again and again. In the process of development of adaptive behavior and social communication, it is necessary to carry out such scattered empirical connection and accumulation. The meaning of the word “theory” should include “the analysis and summary of experience.” Only in this way can it truly become a helmsman who guides us in our practical life.
