According to enunciation, discourse, and polyphony studies present in the dialogic actions, the individual is never linguistically moved by a monological format. However, on the contrary of all that, monological format consists of coercive forces operating in the dialogic process and are identifiable as axiological systems in text construction, whether oral or written. In this regard, the contemporary literary production has been generous with respect to the possibility of analytical exploitation of polyphony present in the characterization of voices which constitute architecturally the volitional-emotional characteristics of narrators and characters. The novel Caderno de um ausente (2014), by John Anzanello Carrascoza, is an example of the exploitation of dialogism, polyphony and silence as architectural procedure of setting up its narrator, as well as its characters. Accordingly, under the Bakhtinian perspective, it is proposed an analysis aiming at investigating how the nature of the boundary between self and other is aesthetically crafted and diluted in this novel.
