The semantic validation of utterances as true or false is known in logic and linguistics. However, linguistic messages are validated not only on the semantic but also on the pragmatic level. In most linguistic studies, pragmatics is defined mostly as the interrelation between speakers and is considered as a mere supplement to semantics. In the authors' approach (called MIC : metainformative centering theory), they give much more importance to pragmatics because they claim that it concerns the necessary meta-informative linear ordering and Old/New validation of any semantic information.
