摘要：The Ancient Greeks, since the sophists‘ texts represented threats to legitimate reasoning anchored in the notion of truth, tried to examine the relationship among valid, informal and fallacious arguments. Aristotle distinguished mainly formal ways of abstractions from the daily practical uses, addressing the relationships between the logical forms and the interferences of content. This paper, motivated by this script of insights, investigates problems concerning logical operators, relations of sense, probability, entailment and their properties in natural language, constituted as inferences in the logical-cognitive-communicative interface. For that, foundations of classical—propositional—logic are brought closer together with the ones from semantics, pragmatics and an inspiring notion of relevance.
