Realizados em conjunto pelo Programa de Pós-Graduação em Filosofia do IFCH e pelo Grupo de Lógica Teórica e Aplicada (GLTA), os Seminários de Lógica (Seminários de Programa e Colloquia Logicae) ocorrem usualmente às quartas-feiras, desenvolvendo intensa programação sobre o tema.

Crispness, Consistency, Necessity...
Sylvain Bromberger has proposed– in more complicate manner than it can be spelt out herein– that in order to understand rational thinking one should firstly consider how questions are selected, namely what makes them distinctive to be admissible as objects of our explanation. The distinctiveness of the questions is arguably based on cognitive constraints rather than on the nature of the subjects. If this is correct, the discovery of the logic operators, regardless of the different they belong to, traces its roots not to the subjects they may apply but to a pre-existent rationality. Thus, for instance, the difference of a crisp concept and fuzzy one is not rooted on the objects one examines, which could, by their very nature, be described fuzzily or crisply, but on the natural way the human mind deals with different objects.
Here we propose a debate on whether the different logic and philosophical notions of crispness and consistency of objects should be treated as equivalent, inasmuch as one can select roughly the same cluster of questions. Maybe crispness is more suitable to explain consistency than necessity.
