"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."

“Thomas Kuhn in his book The Structure of Scientific Revolutions divides all scientists into those who create new paradigms of science and those who work within the established paradigms. The same division may be applied to scholars and philosophers, namely into those who create new paradigms and into those who work within the established ones.”

“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 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.”

“When one turns to psychological models of mental illness, one finds that the psychodynamic model of human mind and of mental disease is also of considerable antiquity. Thus, Empedocles of Agrigentum from whom Hippocrates took the theory of four elements, stressed the importance of emotions of love and hate as the controlling agents of human behavior and of physiological functions.”

“Von Bertalanffy's 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.”

“Another influence of that period was the philosophy of of. Von Bertalanffy met Vaihinger in Vienna and for a time, as a student, lived in his house.10 According to the philosophy of Idealistic Positivism absolute truths and ideal norms of human conduct did not exist, rather man created them as fictions important for the individual and social survival. The idea of relativity of truths and norms postulated by Vainhinger bore a similarity to the relativism of different points of view and categories of thinking postulated by Nicholas of Cusa. The philosophies of Cusanus and Vaihinger were undoubtedly instrumental in shaping von Bertalanffy's 'perspectivist' epistemology and his idea of relativity of categories.”

“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.”
