title: The psychopathology of hallucinations--a methodological analysis.
abstract: A psychiatry based on operational and dynamic principles requires a new definition of hallucinations which is both heuristically useful and helpful for the understanding of the phenomenon of hallucinations. The time-hallowed definition of hallucinations as 'perceptions without stimulation of the sense organs' is both incorrect and a relic of late 19th century para-physiological thinking. Heuristically it leads into a blind alley. Central to the redefinition of hallucinations is the conception of the hallucinator, the author of his hallucinations, homologous to the dreamer, the author of his dreams. This idea was held firmly by early French 19th century clinicians, who were inspired by a holistic and operational conception in philosophy. Hallucinations are a multifaceted complex human mental activity and defined by means of a number of parameters held together as an indivisible whole. Hallucinations are described phenomenologically, psychologically, dynamically, psychodynamically, emotionally, logically, nosologically, and interpersonally.
