《仁学》在西方学者眼中是中国历史上最早以中国古典文献对现代西方哲学和科学框架重新诠释的作品,在中国学者笔下这是近代中国新儒学哲学体系融入现代性全球主义的一次大胆尝试,以求能与当时的国际社会在同一维度上对话。然而《仁学》中谭嗣同以其进化最终带来自由的乐观本体论为导向,援引佛教和道教中对有限性的传统解决方案,提出了超越时间的绝对平等观,这一观念遭到了章太炎的批驳。在章太炎看来,进化最终没有超越混沌,相反,它起源于时间世界,且必须有法律之限制,即基于法之平等与等级,官员和国家试图在此基础上将突发事件和混沌合理化。通过对二人不同哲学观的梳理与对比,清晰反映了那一时期的士人对近代中国传统儒家哲学观念转向的尝试与辩论,这对于归纳传统中国儒家的哲学理念具有一定的参考价值与意义。
