On Material Exclusion and Absolute Contradiction

  • Jonas Rafael Becker ArenhartEmail author


Francesco Berto has argued that a primitive concept of material exclusion could be employed to formulate a notion of absolute contradiction that not even dialetheists could accept. The machinery of material exclusion and absolute contradiction could then be employed as a common (non-question-begging) ground by both dialetheists as well as their opponents in debates about negation and truth. In this paper, we first put the idea on a clear basis, and then present some criticism to it. We shall argue that the concepts of material exclusion and absolute contradiction hardly help with a clear basis for the debate on dialetheism; furthermore, the introduction of material exclusion threatens the coherence of dialetheism by allowing one to express the opposition between designated and undesignated values, with unwanted conclusions.
