"As indicated by its title "A History of Great Ideas in Abnormal Psychology", this book is not just concerned with the chronology of events or with biographical details of great psychiatrists and psychopathologists. It has as its main interest, a study of the ideas underlying theories about mental illness and mental health in the Western world. These are studied according to their historical development from ancient times to the twentieth century. The book discusses the history of ideas about the nature of mental illness, its causation, its treatment and also social attitudes towards mental illness. The conceptions of mental illness are discussed in the context of philosophical ideas about the human mind and the medical theories prevailing in different periods of history. Certain perennial controversies are presented such as those between the psychological and organic approaches to the treatment of mental illness, and those between the focus on disease entities (nosology) versus the focus on individual personalities. The beliefs of primitive societies are discussed, and the development of early scientific ideas about mental illness in Greek and Roman times. The study continues through the medieval age to the Renaissance. More emphasis is then placed on the scientific revolution of the seventeenth century, the enlightenment of the eighteenth, and the emergence of modern psychological and psychiatric ideas concerning psychopathology in the twentieth century."
"The second model is the functionalist model of mind. The organism through acquired S-R responses or through operations on the environmental manages to stay alive and adjust itself to the environment. The Thorndykian and Skinnerian approaches to learning and the adaptive model of the psychoanalytical theory come under this heading."
"There are several definitions of Depersonalization, which are really descriptions of the symptom. The one offered by Schilder (1914) is perhaps most clear and precise. It is given here in a free English translation: The individual feels totally different from his previous being; he does not recognise himself as a person. His actions seem automatic, he behaves as if he were an observer of his own actions. The outside world appears to him strange and new and it has lost the character if reality. The self does not behave any longer in its former way." From this definition it can be seen that the core of the symptom is a change in appearance, a "strangeness" of the object of experience: either the self or the external world or both. There is also a disturbance in the subject-object relationship producing perplexity and interfering with the smooth flow of conscious experience. These aspects of depersonalization are stressed in one form or another by all the investigators of this phenomenon."
"The third model regards mind as an information processing system. This is the model of mind subscribed to by cognitive psychologists and also to some extent by the ego psychologists. Since an acquisition of information entails maximization of negative entropy and complexity, this model of mind assumes mind to be an open system."
"Von Bertalanffys Ph.D. thesis was on the philosophy of , an epigon of the Philosophy of Nature movement, who was also the founder on psychophysics and experimental esthetics, Fechner, like all the other Philosophers of Nature rejected the reductionist-atomist view of nature. He believed that the universe was a living system existing at a higher level than man. It was governed in addition to the law of causality by the laws of stability and of repetition. These three principles causality, stability and repetition governed biological and psychological phenomena."
"Grossly oversimplifying, the following models of mind can be discerned in the welter of contemporary psychological theorizing. The first model of the mind is mind as an energy system. This is represented by early psychoanalytical theory, particularly by its dynamic and economic versions. It has also represented by ecologists (Tinbergen, 1951) and by drive reduction theorists. In this model, the stress is on the concept of motivation, conceived as drive. Common to the theories that regard mind as an energy system are the ideas of homeostasis and closed system. The metaphor of energy is often used by motivation theorists who view drives, instincts, and needs as types of forces."
"Depersonalization is a concept difficult to delineate. It can be regarded as a symptom or as a loosely associated group of symptoms that occurs in psychiatric patients. It can be induced experimentally and also occurs spontaneously in normal subjects. A major obstacle to clearer definition of this concept lies in the fact that it refers to exceedingly private events in the individuals experience. These prove very difficult to describe by a language geared to the description of public (consensually validated) events or private events, such as pain, that occur usually in clearly defined social settings. When it comes to describing and conveying something as ineffable as depersonalization or derealization, the subject resorts to metaphors, "as if" expressions, and figures of speech. The result is semantic confusion. Different authors mean different things when they use the term depersonalization. The concept of depersonalization merges by imperceptible degrees with the concept derealization, the concept of altered body image and self, deja vu, jamais vu, altered time and space perception and so on - the whole gamut of phenomenological description of the experiences of mental patients. Therefore, it is rather difficult to evaluate and to review objectively the psychiatric literature on the phenomena of depersonalization."
