Infectious and transparent emotivism

Abstract

Emotivists like Ayer claim that moral sentences are devoid of cognitive meaning since they only evince attitudinal approval or disapproval of actions. In this paper, I explore two non-classical semantic frameworks for such a view. In particular, I look into the semantics for an infectious logic and a transparent logic. Finally, I show how each of these semantic frameworks accounts for the logical behaviour of these meaningless moral sentences and their upshots to moral reasoning; in particular, how each framework addresses (an emotivist variant of) Jörgensen's dilemma.
