Abstract
In the 21st century, the issue of rethinking the methodology of classification and systematization of knowledge is actualized. New intelligent technologies are widely represented in the methodological apparatus of Prof. V. I. Razumov. A separate element in Razumov's categorical-system methodology is the toolkit for working with categories as cognitive units. Categories, as an opportunity to work at the level of context, are of intellectual value to researchers. In the process of scientific research, the categorical apparatus, in the form of categorical schemes, opens up the possibility of constructing a scientific picture of the world. The range of possibilities of Prof. V. I. Razumov's categorical schemes allows us to apply them depending on individual cognitive characteristics. V. I. Razumov's methodology, based on categories, reveals the potential for studying the problems of interaction between being and essence. In general, Razumov's categorical-system methodology makes it possible to create models that integrate dialectical and synergetic approaches.
