 As a consequence of this strategy, Montague’s paper has many meaning postulates. Nowadays semanticists often prefer to express the semantic properties of individual lexical items directly in their lexical meaning, and then find is directly interpreted as a relation between individuals. Meaning postulates are mainly used to express structural properties of the models (for instance, the structure of the time axis), and to express relations between the meanings of words. For a discussion of the role of meaning postulates, see Zimmermann 1999.
