The authors present a patient with paranoid schizophrenia, who has the delusion that he exists in plural numbers. The patient declares these doubles to be both psychologically and physically completely identical to him, and he believes 'them' to be in fact women. In connection with the case, the authors discuss the phenomena of reduplicative paramnesia and clonal pluralization, and they suggest introducing the psychopathological term 'clonal pluralization of the self' for the reported phenomenon.
