How the individual parts relate

An utterance can be coherent in it semantic orientation and the way it refers to the dramatic situation. It can also contain changes of semantic direction (as we have seen in the Epiphany), and changes in the situational references. It is therefore inherently dialogical in character in so far as its various segments can be assigned different levels of awareness, different types of figure portrayal or different roles of the speaker. Semantic changes in direction may exhibit the transparent tectonics of logical argument, like a refutatio or a rhetorical pattern of disposition.
