In the beginning, ISAT was called Society of Integral Psychoanalysis and was founded in 1970 by the psychoanalyst, philosopher and social scientist Norberto R. Keppe, when he was still working in the sector of Psychosomatic Medicine at the Hospital das Clínicas of the University of São Paulo (USP) who, together with a group of doctors and psychologists, wanted to deepen and develop the discoveries of Sigmund Freud, Melanie Klein and the other schools of psychoanalysis.
Later, Keppe had developed his own theory and methodology which he called Analytical Trilogy (1980) due to the unification he had made in the fields of science, philosophy and theology. As a consequence, the ISAT came to exist and amplify its activities with professionals from other countries in South America, Europe and North America.
Presently, ISAT not only provides sessions of individual and group psychoanalysis, trains professionals in the area of psychoanalysis and psycho-socio-pathology, but also has its own publishing house, radio and television programs, organizes lectures, courses, congresses, seminars and supplies services in the area of psychophysical health care to companies, schools, associations and hospitals among others both domestically and internationally.
ISAT is an association that is strictly of a scientific and cultural philanthropic nature, whose sole aim is research and the application of Integral Psychoanalysis in diverse fields of human knowledge. It is an organization of International scope, and offers a variety of books, some of which are published in up to 9 languages and sold to a number of countries in Europe and the Americas.
