A Study On Williamson’s Theory Of Vagueness

Paradox of vagueness is the result of human actual life, its ideological content of the problem is popular and academic. In history, many academy of logicians put forward their own theories. Cognitive theory has long historical tradition, but it was nor until the Williamson, cognitivism to paradox of vagueness caused a profound explanation. From that time, the contemporary philosophical view of cognitivism had larger change, and substantive outcomes as stick to principle of classical logic cognitive theory also received great attention.Prior to discusses the cognition of socialism of Williamson, the multi-valued logic and super assignment logic analysis and research is necessary. Multi-valued logic and logic are super assignment proposition from the Angle of semantics of binary extended, and although this approach to a certain extent, solve the problem of paradox, but its theory problems still obvious.Based on the criticism to the classical logic, Williamson put forward the priciple of classical binary logic tools, and from the attitudes of cognitivism, vagueness question has carried on the research and analysis, provided us with a return to historical tradition and new perspectives. By rejecting KK principle, Williamson gives a reasonable answer to the ambiguity problem. Williamson’s congnitve viewpoint at the metaphysical level such assumptions are given, the world is clear, everything has accurate boundary conditions, and people’s cognitive ability has a limit.In this article,through conming paradox of vaguness origin, and intruduces the scheme of two typical solution based on the cognition of williamson, represented by socialist plan has carried on the detailed analysis and research, and rise to the vaguness of the ontology level, as a clue to grasp the ambiguity problem itself.
