Concerning the Ancient Greek Ideal of Theoretical Thought. In Hintikka, J., Gruender, D., Agazzi, E. (eds.) Theory Change, Ancient Axiomatics, and Galileo’s Methodology. Synthese Library, vol 145. Dordrecht, D. Reidel Publishing Company, 1981, pp. 113-124

The article was prepared especially for the Second International Conference on the History and Philosophy of Science, held on September 4-8, 1978, in Pisa (Italy). According to the conference program, Popovych's research was presented in the section “Early History of the Axiomatic Method”. Through a logical reconstruction of the theoretical systems of ancient science, the author reassesses the nature of the theoretical achievements of antiquity. Popovych traces the origin of key scientific terms such as analysis, synthesis, logic, and dialectic from ancient philosophy and compares their meanings and peculiarities of use in ancient and modern philosophy. In addition, the article shows the path of ancient philosophers to the realization of the ideal of theoretical thinking by means of logical and philosophical analysis.
