Abstract
A dimensional conceptualization of psychosis that evolved from clinical experience has been replaced in recent decades by a categorical model useful for certain kinds of research. Although both dimensional and categorical paradigms have been valuable ways of viewing “madness,” the loss of a dimensional sensibility is arguably retarding our progress in developing therapies for psychotic suffering.
