The central model for both Sigmund Freud and Carl Gustav Jung for the generation of schizophrenia's hallucinations and delusional system is described as the intrusion of nighttime dream states into the waking consciousness. In this theoretical exegesis, a rent or tear is made in the ego instated by strongly repressed aggressive impulses which then create a dream-world for the patient as they subsequently overwhelm ego defenses. A parallel between this mode of knowing and, for example, the regioning of Martin Heidegger in his Discourse on Thinking is brought forward. Since these modes of thought are analogical and metaphorical, analysis based on this similarity may provide for greater insight into the thought and perceptual disorders of schizophrenia. An understanding of this kind of thought process may then provide a bridge towards more effective therapeutic interventions. A distinction is made between thought processes, per se, and those causal factors of a biological nature.
Since mind has its basis in biological endowment, the contribution of endogenous humoral and biological constitutional factors to schizophrenia's etiology must be considered of profound importance. A complex interaction between heredity and environment provides the substrate of biologically influenced tendencies that work toward or against the onset and reoccurrence of schizophrenia. On this complex base, processes of thought and patterns of behavior are erected which are diagnosed as "normal," "schizoid," "schizophrenic," etc. This paper is concerned with the thought processes and verbal habit patterns which underlie schizophrenia. The genetic and other constitutional factors which may give rise to a tendency to develop schizophrenia and may be thought of as influencing the type of thinking carried out, whether it is realityoriented or has a dreamlike content, are issues which are beyond the scope of this discussion.The exact nature of the interface between the biological substrate of mind and the ontogeny of the symbolic or other process of thought should be related in some lawful manner to the psycholinguistic processes described here. A greater understanding of in vivo neurochemical metabolism as it is influenced by stress due to psychosocial pressures may provide some insight into these questions. The concern of this paper, however, is with resultant symptomologies herein described. In discussions concerning id, ego, and superego functioning, it is not important, as far as this paper is concerned, which psychological processes supervenes. Rather, the concern is with the precise
