“CYBERNETCS AND CONSONANTAL PSYCHOLOGY”, YEAR 1975 - Scientific communication at The Third International Congress of Cybernetics and Systems, Bucharest, Romania, August 25-29, 1975 (ASE Bucharest). The paper appeared in Proceedings of Congres (editors J. Rose-UJ and C Bilciu-Romania), Vol. II, section 5 (Communications, Education and Informatics), SPRINGER-VERLAG Berlin, Heidelberg, New York. The author presents the connection between the basic concepts of cybernetics and the ideas presented in detail in the volume "Consonantal Psychology", Paris, 1938-1939. Consonantal psychology views the brain as a thinking machine; it proceeds to the analysis of thinking in a mechanical, modern way and separates distinctly the two primordial categories (psychological and dynamic question). Thus, Dr. Ștefan Odobleja can be considered a forerunner of Artificial Intelligence.
