Abstract

Gaetano commented on the problems that exist in diagnosing schizophrenia and argues that more effort should be devoted to understanding relevant subjective experiences. I am not convinced that this is necessarily so. I have argued previously that diagnosis of clinical disorders is unlikely to work well in the absence of a theory on which the diagnostic system can be based. At present, there is very little theory concerning schizophrenic disorders, or at least very little theory that elicits wide agreement and has definitive empirical support.
