On not being a dentist

Resumo

Negative properties, like not flying, are controversial. I oppose Chateaubriand’s view on these properties and offer semantic arguments against their inclusion in ontology. I distinguish predicate negation and sentential negation, and examine the syntactic and semantic behaviour of predicate negation. I contend that predicate negation is identical with sentential negation. If it is not, then we lose a lot of intuitive inferences found in natural languages and make no clear metaphysical gain. Other arguments based on Ockham’s razor are offered.
