Deep disagreement is characterized as being a disagreement in which the interlocutors are unable to reach a common agreement or position on the problem under discussion. However, deep disagreement can be solved irrationally, that is, through fallacious persuasive techniques. One of the objectives of this work is to investigate the debate on deep disagreement in both dialectical and epistemic contexts, and to provide some elements that would allow the concept to be better encompassed in some theoretical framework suitable for analysis. As a hypothesis of this work, it is argued that there is no disagreement between logics, but disagreement between agents or subjects. A structure of belief systems is exposed based on the substantive beliefs that lead by inference to the derived beliefs. Mathematical and epistemological development of a theory of deep disagreement is based on the topological structure of belief systems.
