 Mally’s deontic logic is unacceptable for the reasons stated by Menger (1939). But it is not as bad as it may seem at first sight. Only relatively minor modifications are needed to turn it into a more acceptable system. One may either change the non-deontic basis to get either a system that is similar to Anderson’s system or a system that is identical with intuitionistic or constructive propositional logic with double negation as an obligation-like operator, or apply two patches to the deontic postulates to obtain a system similar to standard deontic logic.
