说起中国人近代的大同理想,人们最先想到的往往是康有为和《大同书》,这也在无形中减弱了对谭嗣同大同思想的关注。其实,谭嗣同与康有为一样对大同社会津津乐道,并且对大同社会提出了种种畅想。两人的大同思想呈现出诸多相同之处,一起推出了近代大同形态的第一阶段。比较康有为、谭嗣同大同思想的相同点,有助于领略戊戌启蒙思想家的大同思想的共同特征,进而深入了解戊戌启蒙思潮的主旨诉求和历史局限。 When we talk about the modern Chinese ideal of common ground, what people first think of is that Kang Youwei and the “Great Harmony Book,” which virtually weakened the concern for Tan Sitong’s philosophy. In fact, Tan Sitong, like Kang You-wei, relished his talk with the community of Datong and put forward various imaginations for the society in the world. The two have shown many similarities in common ground and jointly launched the first phase of modern Datong’s formation. Comparing the similarities between Kang Youwei and Tan Sitong in the thought of Datong helps to understand the common characteristics of the Datong-tong thought of the Enlightenment thinkers in 1898, and then to understand in depth the historical aspirations and historical limitations of the Enlightenment of the 1898 era.
