Abstract

GARCIA DUQUE, Carlos Emilio; ARANGO GIRALDO, Pablo Rolando  and  POSADA RAMIREZ, Jorge Gregorio. A proposal to foster the intuitive understanding of logical validity. discus.filos [online]. 2016, vol.17, n.29, pp.65-78. ISSN 0124-6127.  http://dx.doi.org/10.17151/difil.2016.17.29.5.

This paper introduces a suggestion to foster the intuitive comprehension of the notions of possibility, necessity and argumental validity. By using a psychological criterion, our method tries to promote an intuitive apprehension of such notions by the students, before they start using formal proofs of validity. We show how to adapt these suggestions to the drawing of Venn diagrams and to the diagramming of some syllogistic forms that classical theory of syllogism treated as valid but that are not considered valid in the modern treatment that uses Venn diagrams.

Keywords : Possibility; necessity; validity; Venn; Bennett; Holt; García.
