Abstract
In this paper it is argued that uncertainty and vagueness are two distinct empirical phenomena and they must be explored by means of two distinct theories: probability theory and fuzzy sets theory respectively. The assertions of the first theory can be verified to be true or false in some model, on the contrary, the typical expressions of fuzzy sets theory are not interpreted in any domain, they rather form a kind of interpretation.
Keywords: uncertainty, vagueness, probability theory, fuzzy sets theory
