NICOLAS FRANCISCO, Ricardo Arturo  e  ESTRADA GONZALEZ, Luis. Sí hay negación lógica. Crítica (Méx., D.F.) [online]. 2020, vol.52, n.155, pp.55-72.  Epub 20-Ago-2021. ISSN 0011-1503.  https://doi.org/10.22201/iifs.18704905e.2020.1194.

In this paper we discuss Jc Beall’s thesis that there is no logical negation. We asses the soundness of Beall’s argument and we put forward two reasons to negate the truth of one of its premises: that negation has to be whether exclusive or exhaustive. The first reason involves an alternative presentation of the rules for negation in sequent systems different to that presupposed by Beall. The second reason establishes that negation need not be neither exclusive nor exhaustive.

Palavras-chave : exclusivity; exhaustivity; FDE; separatism; interactionism.
