理气纠缠:规范性动力——对“形著论”倾向的反思

新儒家批判朱熹心性哲学缺失“道德本心”,导致“性”“天道”的超越性、根源性在主体层面无法落实,而为朱熹做辩护的核心就在于证成“道德本心”。当下流行的框架是利用“形著论”框架:“性”对自己的自觉即是“心”。这种策略忽略了“性”兼理气所带来的道德本心指称不确定性问题,因此,“形著论”框架是不适合的。“理气纠缠”结构是一种新的解决模型:“理”“气”在“无始无终”的过程中形成规范性与动力的互补性结构,这个结构凸显了朱熹对于宇宙秩序和人类行为规范性及动力的关注。“理气纠缠”在伦理学上表达为“规范性动力”,有两层含义:第一,主体行为实践的动力的规范性;第二,主体在面临困难境遇时,对于“本分”的“勇敢果决”的积极实践动力。

KdV Equation with Self-consistent Sources in Non-uniform Media

Two non-isospectral KdV equations with self-consistent sources are derived. Gauge transformation between the first non-isospectral KdV equation with self-consistent sources （corresponding to λt = -2aA） and its isospectral counterpart is given, from which exact solutions for the first non-isospectral KdV equation with self-consistent sources is easily listed. Besides, the soliton solutions for the two equations are obtained by means of Hirota＇s method and Wronskian technique, respectively. Meanwhile, the dynamical properties for these solutions are investigated.
