One of the most important tasks in each philosophical tradition is to determine the methodological foundations and the target reason for research practice. Russian Russian neo-Kantianism raises several fundamental questions, including the criteria for distinguishing individual systems and the possibility of their integral reconstruction, the identification of the independence of Russian philosophers in overcoming the key contradictions of transcendental idealism, as well as discussions regarding the contribution of Russian neo-Kantians to the history of the development of Russian and European philosophy. No less significant is the problem of uniting Russian neo-Kantianism in the context of the general tradition of neo-Kantianism in its development to the latest trends. The prospect of turning to the heritage of Russian philosophers is largely determined by the design of post-Kantianism and post-Neo-Kantianism. In the works of A.I. Vvedensky, and then B.A. Focht, V.E. Seseman, S.L. Rubinstein, and many others, the transition from German classical idealism in the prism of the specifics of Russian philosophy to the formation of a new understanding of transcendental philosophy and its tasks was marked. In many ways, the proposed solutions were distinguished by originality and obvious independence, but at the same time they were implicitly within the boundaries of the tradition of German neo-Kantian philosophy set by I. Kant. Comparing the latest prospects for the development of neo-Kantian methodology, it can be assumed, not without reason, that Russian neo-Kantianism has largely anticipated the latest trends. Russian neo-Kantians need to reveal the unity of the entire tradition for an objective assessment and subsequent actualization of the heritage of the

Russian Neo-Kantians, accompanying this process with a historical and philosophical reconstruction of individual systems of philosophy, but also identifying those perspectives for philosophy that were designated by Russian thinkers. Russian neo-Kantians' problem field of self-determination within the framework of the history of Russian and European philosophy is proposed in the content of the article. Special attention is focused on the unity of methodological tasks and the target reason for the research practices of thinkers who at different stages of their development contributed to the formation of the phenomenon of Russian neo-Kantianism.
