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 preceding chapters described various models of mental illness. Seven major varieties of models have been described. Seven major varieties of models have been described. Three are scientific: medical, psychological, and sociocultural. Four are philosophical-moral: hermeneutic-linguistic, phenomenological- existential, humanistic, and moral-legal. Most of these major varieties can be divided into more circumscribed models giving rise to a total number of fifteen. In turn, some of these may be further divided into submodels. Thus, there are three psychodynamic, three behaviouristic, two cognitive, two macro- and two microsocial, two linguistic-symbolic, # two phenomenological, two humanistic, two hypersanity, and three moral-legal submodels. The detailed classification of the models of mental illness is presented in Tabel II.

Von Bertalanffy also studied the works of , a neo-Platonist Renaissance philosopher, on whom he wrote a book. Cusanus, who had a lasting influence on von Bertalanffy, may be regarded as a precursor of general systems theory. Nicholas of Cusa rejected Aristotelianism dominant in theology and philosophy at the end of the middle ages and adopted neo-Platonist ideas and even went back to the philosophy of , a pre-Socratic philosopher. Anaxogoras said that 'everything was everything else.' Therefore all categories of thinking were relative and all contradictions only apparent. According to Cusanus the knowledge of infinite God cannot be grasped by human mind it can only be approached from different directions. The idea of God has many aspects which appear to be contradictory. It is similar to a human face which may present different appearances when perceived from different perspectives.
