The Movement Between Agreement and Disagreement in Self Positions Through a Musico-Logical Metaphor.

In this article, I use a metaphorical concept in order to propose an interpretation for the dialogical relationship that occurs between I-positions in the human self. Metaphor is a useful tool for scientific production and its heuristic value has been demonstrated in several fields of knowledge. I claim a musico-logical metaphor to explain dynamic dialogic processes that occur when I-positions are in agreement or disagreement relationship. These dialogic processes are based on tension and release and, in a complementary way, can result in contradictory, tautological, or contingency relations between I-positions. These relations were categorized using concepts from Music and Logic, thus creating a theoretical model composed of metaphorical concepts. To provide evidence of how a musico-logical metaphor might contribute to the interpretation of relations between I-positions in the system of self, I discuss a case study of a rural worker and analyze how child labor marked his life trajectory throughout different moments. The musico-logical metaphor might contribute to dialogical processes understanding that occur at the border of the agreement-disagreement dyad in the system of the self, since this metaphor proposes to identify, from a cogenetic understanding, dialogic interactions between I-positions located in this border, thus transforming the agreement-disagreement dyad into a triadic agreement-border-non-agreement set.
