2019 marks a centenary of the first Department of International Politics. It is a good opportunity to cast a retrospective look at International Relations' (IR) development as an independent cluster of academic disciplines. This cluster is evaluated in terms of maturity of its subject and its methodology. The authors present their reaction to the article by Alexey Fenenko, which rekindled the timely discussion of applicability of quantitative methods in international politics research. The authors present their view on the issue, contest Feneko's position, and compare the International Relations development in Russia and abroad. In the article reasons for existing differences between the two are emphasized, the place of the method per se is determined, and epistemological role of quantitative and qualitative analysis in the study of international life is outlined. The Russian school of IR in contrast to the established global one still finds itself at the methodological and, in this sense, pre-scientific stage of development, at which there is no “normal science” agreement on acceptable research methods. It remains considerably fragmented in the nature of the subject of inquiry and in the achievability of objective knowledge. In conclusion, the authors set their normative vision of epistemological and methodological balance, as well as schools of IR adhering to different ontological basis.
