Relational propositions in discourse

In addition to the propositions represented explicitly by independent clauses in a text, there are almost as many propositions, here called relational propositions, which arise (often implicitly) out of combinations of these clauses. The predicates of these propositions are members of a small set of general, highly recurrent relational predicates, such as “cause,” “justification,” and “solutionhood.” Often unsignalled, these relational propositions can be shown to be the basis for various kinds of inferences and to function as elements of communicative acts. Examining two natural texts, we see that the relational propositions involve every clause, and that they occur in a pattern of propositions which connects all of the clauses together. This examination also shows how the relational propositions are essential to the functioning of the text.
