摘要
模态逻辑不仅涉及逻辑的可能性,也涉及事实的可能性,两者存在着重要的差异;在对“罗斯悖论”的剖析中引入可能算子,通过对道义悖论作时态的分析,以辨明义务的相对性,是消除道义悖论的一条可行的途径。
There are some theoretical problems in the study of generalized modal logic. Modal logic is involved with not only logical possibility but also actual possibility. The two possibilities both have important disparities. We may use the possibility operator to make an analysis of the Ross Paradox. A tense analysis of deontic paradoxes is useful. It can make us understand the relativity of obligation and eliminate the deontic paradoxes. As an expansion of classical logic, generalized modal logic has both advantages and disadvantages.
