 The aspect of Fusco (2015) of present concern is the treatment of disjunction, with special reference to the problems with which it is associated in deontic logic – such as Ross’s Paradox, and the representation of Free Choice permission. The issue is discussed further in Section 3 of Fusco (2019). (For general background, including these problems, see McNamara 2019; more detail on the specifically disjunction-related issues arising is provided in Aloni 2016.) Fusco (2015) argues, on grounds we do not go into here (since they involve several parts of an elaborate theory of deontic notions), that these problems of deontically embedded “or” in English (and corresponding vocabulary in other natural languages) are best treated rendering it formally by means of “ or ”, with φ or ψ defined as:
