The distinction between one- and two-level versions of DRT is of interest for at least two reasons. First, once we go beyond basic DRT, the two-stage system may actually be more economical overall. For example, if DRT is extended for dealing with presuppositions (see Section 5), the one-pass approach becomes unwieldy. Secondly, and perhaps more importantly, two-stage theories may be viewed as implementing a distinction between semantics and pragmatics which has some prima facie plausibility: in the first stage a representation is computed which is projected from the sentence’s lexico-grammatical structure, while in the second stage, context-dependent aspects of meaning are dealt with.  This division of labor is reminiscent of the traditional dichotomy between compositional semantics and non-compositional pragmatics, but it should be noted that the two do not coincide. Usually, the “semantical” part of a two-stage version of DRT is not compositional in the Fregean sense, because its output is essentially incomplete; it may contain anaphoric “gaps”, for example. Therefore, even if a sentence DRS admits of a truth-conditional interpretation, it will typically fall short of capturing everything that is conventionally thought to belong to truth-conditional content.
