Abstract

This article discusses C. E. Alchourrdn and E. Bulygin's ideas regarding the distinction between strong permission and weak permission. The author takes for granted that the distinction between the two terms should be placed at the level of the assertive metalanguage about norms. But the symbolizations and the definitions of strong and weak permissions offered by Alchourrdn and Bulygin, as well as their thesis concerning the relations between the two concepts are challenged.
