Conoscenza e logica. Spunti da Strawson

Strawson rightly maintened that formal logic is not satisfactory when it is applied to natural language, because natural language contains terms with an implicit logic, that cannot be completely encompassed by formal rules of inference. But Strawson did not grasp that this is a consequence of the epistemic human condition, which is constantly changing, since all the relevant information are never available; on the contrary formal logic presupposes a context in which the information is complete and definitive. Our inferences often get away from the deductive model, exploiting an open-textured rationality, not exhausted by the demonstrative procedures of logic and mathematics
