凌空蹈虚是当下中国思想界的主要病症。尽管在学术理想与学术抱负上新世纪之后确实有了重大改观,在直面人类生存方面的理论勇气尤其让人刮目相看。可惜的是,有关中国现代思想的实体建构却始终存在着“思想落地”的困境。本文的研究与思考以为,重构具有可欲性和正当性的社会秩序乃至世界秩序,除了合理运用古今中外的各种理论资源之外,还须对这些资源的不同理路做出理论化处理和重思;在对全新的历史情势做出准确诊断的同时,尤须以中国为根据,以中国问题为出发点,方能确立中国理论发动和知识创造的真正可能性。 Loftdance is the main symptom of the current Chinese intellectual community. Although there has indeed been a significant change since the new century in academic ideals and academic aspirations, the theoretical courage in the face of human existence is especially impressive. What is a pity is that the substantive construction of China’s modern thought always exists the dilemma of “thinking”. The research and thinking of this article think that, in order to reconstruct the social order and the world order of desirability and legitimacy, in addition to making rational use of all kinds of theoretical resources at all times and in all countries, we must theoretically deal with the different ways of these resources At the same time, it is especially necessary to take China as a basis and China’s issue as a starting point so as to establish the real possibility of launching China’s theory and creating knowledge, while making an accurate diagnosis of a completely new historical situation.
