Abstract

CAMPOS BENITEZ, Juan Manuel. Kazimierz Ajdukiewicz, the interrogative sentences and the presupposed rationality when asking a question. Tóp. Sem [online]. 2016, n.36, pp.121-138. ISSN 2594-0619.

We show some ideas from the polish philosopher Kazimierz Ajdukiewicz about interrogative sentences and some classifications of answers. We resort to First Order and Doxastic Logic in order to express some of his results and we also recourse to normal and non normal squares and hexagons of opposition to express his findings. Finally we say some words about a relationship found in the medieval octagons of opposition which is not found in the traditional square; this relation is found also in our doxastic hexagon of presuppositions.

Keywords : Ajdukiewicz; interrogative sentences; presuppositions; doxastic; oppositions.
