چكيده لاتين :
Michael Dummett tries to explain Fregeʹs theory of reference by using semantic roles of expressions. The definitions which he gives for "semantic role" and "sense" results in regarding them as equivalent and as a result the sentences which contain empty proper names, because of having sense, will have semantic roles and "not true and not false" would be a third kind of truth - values. Dummettʹs view results in accepting three - valued logic which can not be attributed to Frege who believes in bivalence logic.
