The paper critically discusses the purported solution to Jørgensen’s dilemma recently put forward by Daniel Mendonca. In particular, it aims at pointing up three difficulties of this proposal: (1) the apparent overcoming of the dilemma actually consists in simply embracing its first horn (i.e. norms have truth-values, albeit peculiar), (2) the three-valued logic which stems from the tables with two variables leads one to validate inferences which derive “ought” from “is” and vice versa, (3) such a logic also validates some implications between norms, which are completely at odds with our common definitions of the deontic modalities.

Abstract

The paper critically discusses the purported solution to Jørgensen’s dilemma recently put forward by Daniel Mendonca. In particular, it aims at pointing up three difficulties of this proposal: (1) the apparent overcoming of the dilemma actually consists in simply embracing its first horn (i.e. norms have truth-values, albeit peculiar), (2) the three-valued logic which stems from the tables with two variables leads one to validate inferences which derive “ought” from “is” and vice versa, (3) such a logic also validates some implications between norms, which are completely at odds with our common definitions of the deontic modalities.
