On Deontic Logic,Action Logic and Logic about Norms
Zhou Zhen · Journal of Guangzhou University · 2002
Deontic logic established by Von Wright in 1950's is firstly named as logic about action name. Later on,it gave rise to two research lines:the one is logical research about what ought to do,the other is logical research about what ought to be.In the former case,logic about action name developed to be a probe into action logic in analysing action sentence.Then deontic logic became a theory of dynamic logic based on action logic.This deontic logic should be logic about normal propositions rather than logic about norms.To a great extent,it can be seen as a kind of hybrid status in relation to both logic about normal proposition and logic about norms.
