This paper offers a phenomenological or hermeneutic reading—employing Heidegger's notion of the 'ontological difference'—of certain central aspects of schizophrenic experience. The main focus is on signs and symptoms that have traditionally been taken to indicate either 'poor reality-testing' or else 'poverty of content of speech' (defined in the Diagnostic and Statistical Manual of Mental Disorders III-R as: “speech that is adequate in amount but conveys little information because of vagueness, empty repetitions, or use of stereotyped or obscure phrases"). I argue (...) that, at least in some cases, the tendency to attribute these signs of illness to the schizophrenic patient results from a failure to recognize that such patients—as part of a quasi-solipsistic orientation and alienation from more normal, pragmatic concerns—may be grappling with issues of what Heidegger would call an ontological rather than an ontic type, issues concerned not with entities but with Being (i.e. not with objects in the world but with the overall status of the world itself). An application of the Heideggerian concept of the ontological difference has the potential to alter one's sense of the lived-worlds of such patients, of what they may be attempting to communicate, and of why communication with them so often breaks down.

Auditory verbal hallucinations form an essential criterial feature in the schizophrenia definition in the Diagnostic and Statistical Manual of Mental Disorders -IV and International Classification of Diseases -10. In both classificatory systems, the presence of a hallucinatory voice that continuously comments the patient’s behavior or thoughts, or the presence of several voices that discuss the patient with each other, is a sufficient criterion to diagnose schizophrenia. The DSM-IV defines a hallucination as “a sensory perception that has the..

This article examines the supposedly incomprehensibility of schizophrenic delusions. According to the contemporary classificatory systems (DSM-IV-TR and ICD-10), some delusions typically found in schizophrenia are considered bizarre and incomprehensible. The aim of this article is to discuss the notion of understanding that deems these delusions incomprehensible and to see if it is possible to comprehend these delusions if we apply another notion of understanding. First, I discuss the contemporary schizophrenia definitions and their inherent problems, and I argue that the notion (...) of incomprehensibility in these definitions rests heavily on Jaspers’ notions of understanding and empathy. Secondly, I discuss two Wittgensteinian attempts to comprehend bizarre delusions: (a) Campbell’s proposal to conceive delusions as framework propositions and (b) Sass’s suggestion to interpret delusions in the light of solipsism. Finally, I discuss the phenomenological conception of schizophrenia, which conceives delusion formation as resulting from alterations of the structure of experiencing and from underlying self-disorders. I argue that although a psychological understanding that seeks to grasp meaning in terms of motivations, desires, and other more straightforward psychological connections between mental states is impossible in schizophrenia, we can in fact have a philosophical understanding of the schizophrenic world and of the emergence of delusions typically found in schizophrenia.
