Moral Dilemmas and Deontic Logic
Languages of publication
In the paper I discuss an argument of deontic logic concerning the problem of the existence of moral dilemmas. First, I draw attention to the philosophical context of this argument and present three proofs which reveal an inconsistency in the nature of moral dilemmas. These proofs, however, are philosophically and logically controversial. Accordingly, I provide an alternative proof, based on the LP-system of deontic logic. The system is described from syntactic and semantic point of view. Assuming only the noncontroversial axiom K and a certain formulation of Elzenberg’s principle, I argue that, from the point of view of the LP-system, there is an inconsistency in the definition of moral dilemmas.
