El cuadro de oposición como instrumento de la lógica: su uso y aplicaciones en Tomás de Mercado

Abstract

Logic, as a knowledge instrument, was developed since and during the preaching of the Gospel in our American lands. The New Spain authors make use of the square of opposition —which they spread to unsuspected points— in order to introduce their logic doctrine. In this work I will show some of the square uses in the temporal and modal logic, and Tomás de Mercado’s quantified modality. The square’s logical doctrine and its uses can be compared to nowadays logic’s extensions.
