【摘要】：以往解决“休谟问题”的各种推导方法都不是普遍有效的。这启示我们 ,与其探索“实然”与“应然”间还无从定性的关系 ,不如从“应然”开始 ,探索蕴涵“应然问题”的必然前提。经分析 ,“应然问题”的充要条件是“可以这样做 ,也可以那样做”的“可然” ,而“实然”则只是部分“应然问题”的间接前提。在逻辑上我们可以做从“实然”到“应然”的推导 ,但在实践层面只适宜从需要解决的“应然问题”开始推导“应然”。这个推导过程的关键是“可然”到“应然”的过渡 ,基本方法是比较评价法
[Abstract]:In the past, all kinds of derivation methods to solve Hume problem are not universal and effective. This enlightens us that rather than exploring the uncertain relationship between "reality" and "ought", we should begin with "ought" and explore the inevitable premise of implying "ought to be". Through analysis, the necessary and sufficient condition of the "ought problem" is that "can be done in this way as well as in that way", while the "reality" is only the indirect premise of the "supposed problem". Logically, we can deduce from "real" to "ought", but in practice, we can only start with "ought" problem that needs to be solved. The key to this derivation process is the transition from "can" to "ought", and the basic method is the comparative evaluation method.
