عنوان مقاله [English]
In this paper I expose and evaluate supervaluationist theory of vagueness. Specially, I concentrate on the standard version of it. This criticism is twofold: first, this theory cannot model all intuitions about vague predicates and though it select a proper subset of these intuitions, its preference is not justified; second, its psychological solution of sorites paradoxes either is not satisfactory or is ad hoc. I will conclude that, at least, standard version of supervaluationism does not handle vagueness related problems.
