LOPEZ-ORELLANA, Rodrigo  and  REDMOND, Juan. Dialogical Assertion as a Minimum Unit of Knowledge. Tópicos (México) [online]. 2021, n.60, pp.103-151.  Epub Feb 23, 2021. ISSN 0188-6649.  https://doi.org/10.21555/top.v0i60.1136.

The aim of this paper is to propose the notion of dialogical as- sertion as a minimal unit of knowledge in the frame of dialogical pragmatism. We argue that this minimal unity is the dialogue for the p thesis, accompanied by its game of giving and asking for reasons (Play-Level) for a winning strategy for the propo- nent. Thereby, we explore the problem from the semantic frame- work proposed by Shahid Rahman to present a dialogical defi- nition of that concept. Furthermore, we show how the notion of proposition ceases to be the primordial logical concept and how it is replaced by the notion of assertion as an act in the process of a dialogue game and following the fundamental insights of Brandom (1994, 2000) and Martin-Löf (1984). This pragmatic ap- proach to logic will abandon the idea that the proposition is the minimum logical unit of true knowledge.
