Does Schizophrenia Exist?

Abstract

This paper develops and defends a deflationary analysis of existence claims involving psychiatric disorders. According to this analysis, a given psychiatric disorder exists if, and only if, there are people who have the disorder. The implications of this analysis are spelled out for our views of nosological decision making, and for the relationship between claims about the existence of psychiatric disorders and claims about their reality. A pragmatic view of psychiatric nosology is defended and it is argued that worries about the “reality” of any given disorder have to be distinguished clearly from questions about its existence.
