康有为的大同思想是我国乃至世界有史以来最杰出、最详尽的空想社会主义杰作之一。它不仅是中国近代社会也是全世界人民灾难深重的曲折反映,同时也是人类关于未来社会前景的一种最美丽、最大胆的设想。然而,长期以来人们在研究这一思想时往往侧重于对《大同书》的研究和解读,而忽视了对这一思想的形成发展过程尤其是康有为早期著作中相关思想内容的发掘,因此造成的不良后果至少有两个方面:一、让人感觉康有为的大同思想只是伴随《大同书》的诞生而出现的,它很可能是一种孤立或偶然的现象;二、对《大同书》的基本思想及其社会作用的评价众说纷纭,乃至出现一些很不客观甚至歪曲的见解。本文拟从康有为早期的几部代表作入手,深入挖掘其中的核心信息,以此来揭示其大同思想的产生根源和发展轨迹。期盼此举能有助于学界同仁对这一思想在认识上进一步升华,从而对其作出相对理性和准确客观的评价。 Kang Youwei’s thinking on the Great Harmony is one of the most outstanding and the most elaborate utopian socialism ever made in our country and in the world. It is not only a twists and turns reflection of the disaster in modern China and the world but also one of the most beautiful and daring assumptions about the future prospects of society for mankind. However, for a long period of time, people often focus on the research and interpretation of the “Great Harmony Book” while neglecting the excavation of the formation and development of this thought, especially the relevant ideological contents in Kang Youwei’s earlier works, There are at least two aspects to the unhealthy consequences: First, people think that Kang Youwei’s thinking on Datong is only accompanied by the birth of “Datong Book,” which is likely to be an isolated or accidental phenomenon. Second, There are many different opinions on the evaluation of the thought and its social function, and even some very objective and even distorted opinions. This article intends to start with some of the early Representatives of Kang Youwei to dig deep into the core information in order to reveal the origin and development path of his thinking on the Great Harmony. Looking forward to this move can help academic colleagues to further sublimate this idea in order to make a relatively rational and accurate objective assessment of it.
