Are Ontological Questions Really Meaningless?

An influential critique of ontology, traditionally linked to Rudolf Carnap, logical empiricism, and verificationism, has it that ontological questions and statements are meaningless. In recent years, Amie Thomasson has revived this Carnapian critique, albeit in a non-verificationist version. This chapter argues that the meaningfulness of ontological statements can be vindicated by appealing to considerations compatible with Thomasson’s Carnapian approach. Two possible avenues are explored. The first is that of specifying the assertibility conditions of ontological statements like ‘There are Fs’, by providing an adequate rule of use. The second is that of spelling out the truth-conditions of the same ontological statements by means of a T-schema where the right-hand side is a sentence formulated in a language specifically introduced for doing ontology—what several authors call ‘Ontologese’. It is proposed that Ontologese be introduced as a bona-fide Carnapian framework, and this option is defended against a number of objections.
