This book shows how the authorship understood as a discursive position in Brazilian oral narratives leads to a discursive turn in the ideological naturalization of superiority of writing in literacy practices. The relationship between positions of authorship found in specific literacy practices, in the case of oral narratives of Brazilian fiction, is presented from the correlation between discursive memory and myth. It is understood that the myths are both, in the form of impossibility of marking the origin of words in the oral tradition, and as an individual update of the enigmatic dimension of the discursive subject, part of the setup and characterization of literacy practices.Back to the relationship between myth and truth pointed at the beginning, we see that it elicits a form of contradiction that also appears in the relationship of alterity between orality and writing. By betting this otherness, this work stands in an effort to oppose to the interpretive dichotomy between the assumption of the effects of truth of the discursive subject limited to writing and practicing common language.
