译文探讨【P2 discursive rationality】
有些论者把理性（reason）和清晰的理解解释为说理理性（discursive rationality），在本书中我多处表示，这样的解释损害了伦理思想本身，也扭曲了我们对伦理思想的认知。但我既然作为一个哲学作者提出这样的主张，它们若要有说服力，它们自己也最好是以一定程度的明述理性和论证方式呈现出来，这正是我努力去做的。
原文： 
I suggest in the course of the book that certain interpretations of reason and clear understanding as discursive rationality have damaged ethical thought itself and distorted our conceptions of it. But if claims of that sort are to carry conviction in coming from a philosophical writer, they are themselves best set out with some degree of discursive rationality and argumentative order, and that is what I have tried to give them.
同一段话里先译成“说理理性”，后又译成“明述理性”，似乎不妥。

若望师建议“推论式理性”，似乎也不错。但个人觉得“推论”包含了太强的“从既有前提出发”的意思，而discursive rationality毋宁说是在把一切理论化之际，设定一些适于运用推理计算的前提。
