Two aspects of the utterance
According to Bakhtin, there is an aspect that comes from language and Todorov tells us it's iterative (denotative - can be understood by all) and then there's the part that comes from the context of enunciation, and this is unique, noniterative (TT 49)
There's also the distinction between the "given" and the "created" in the utterance - and the "created" always has relation to value (truth, the good, the beautiful) - but what's critical, is that this comes into being through language.
To study the given in the created (for example: the language, the already constituted general elements of the conception of the world, the reflected rea facts, etc.) is far easier than the study of the created itself. Frequently, scholarly analysis as a whole winds up doing nothing more than making explicit all that is already present and constituted before the world (what was found and not created). (As quoted in TT 50)
