К. Луис и теорията на строгата импликация
C. Lewis and the Theory of the Strict Implication

Summary/Abstract: There are paradoxes in the theory of strict implication which are analogical to the paradoxes of material implication. The reason is that the systems of Lewis are extensions of the classical logic. According to us, the strict implication cannot express the "inner" necessary relation between the statements, because the operator of necessity is applied externally to a formula which contains the material implication. The entailment in this formula is determinate by the truth-values of propositions analogically to the classical tradition. Therefore the strict implication does not concern the entailment between the propositions. According to us, the operator, denoting the logical entailment, has to be a binary operator of necessity.
