Abstract

This paper has two parts: Part I is a continuation of the work [10] and as well as this it deals mainly with the logic of an auxiliary (semantical) theory, ST , in effect generally considered (by textbooks) within the semantics for a typical theory T of general relativity; and especially the modal features of this auxiliary theory are studied. Part II deals with the influence had by relativistic theories and especially by the new notion of space-time on pragmatic languages (in Carnap’s sense), so that they include, e.g., „now” and „here”
