Kislov, Alexey

The paper presents the semantics of deontic logic, which is implemented on the basis on propositional dynamic logic. The standard version is a relational semantics (J.-J. Ch. Meyer), which uses the semantic idea of A. Anderson – the definition of normative operators (“obligatory”, “forbidden” and “permitted”) by means of propositional constant “sanction”. The standard semantics of multimodal way (without the mutual definability of deontic modalities) is complemented by “strict” operators (the concept of “degree of responsibility” is discussed), then – “pragmatic” operators (through propositional constant of S. Kanger “positive sanction”). The opportunity to refuse from total reduction of deontic logic to dynamic logic and to semantically questionable constants “sanction” and “positive sanction” is offered. An autonomous intensional semantics of deontic operators, which is relative regarding the rating system, is constructed. The proposed semantics being close to the “constant” version retains the ability to express a class of deontic operators “in the strict sense” and combines standard and pragmatic interpretation of deontic operators. However in our opinion, the most important fact is that “non-reductionist” multimodal version of deontic semantics is more than natural.

Keywords: deontic logic, propositional dynamic logic, logical semantics, normative operators, sanction, degree of responsibility, ratings system.
