W. argues that generative text linguistics should take the form of a grammar sensitive to coherence. Coherence is realized by the machinery of emphasis, whose three subtypes (accent, reduction, and contrast) occur in texts depending upon the anaphoricity of information as it proceeds through them. This hypothesis, taken together with a condition stating that anaphoric elements tend towards the beginning of sentences, can be used to explain a large number of movement rules such as passivization.
