nounfemininepl: proposições contingentes
proposição contingente
1. A proposition in logic that is neither necessarily true nor necessarily false; a statement whose truth value depends on contingent facts about the world
The statement 'It is raining today' is a contingent proposition because it could be true or false depending on actual weather conditions.
A afirmação 'Está chovendo hoje' é uma proposição contingente porque pode ser verdadeira ou falsa dependendo das condições meteorológicas reais.
2. In philosophy and metaphysics, a proposition whose truth is not determined by logic alone but depends on empirical facts or possible worlds
Unlike tautologies, contingent propositions require observation of reality to determine their truth value.
Diferentemente das tautologias, proposições contingentes requerem a observação da realidade para determinar seu valor de verdade.
This term is primarily used in academic and philosophical contexts in both Brazil and Portugal. It is fundamental to logic courses, philosophy departments, and formal semantic studies. The concept originates from classical logic and modal logic philosophy, with deep roots in Aristotelian and Leibnizian thought. Usage is formal and technical, not encountered in everyday conversation.
