Problem of Mediating: L.S. Vygotsky, A.N. Leontiev, D.N. Uznadze

The subject of discussion in the presented article is the “immediacy postulate” and the task of overcoming it, specified in the methodological principle of mediating a two-term scheme of analysis. The options for solving the problem of mediation contained in the theoretical systems of L.S. Vygotsky, A.N. Leontiev and D.N. Uznadze are considered and analysed. D.N. Uznadze, who was the first to designate this methodological discourse, and A.N. Leontiev represented its essence approximately the same way, namely, as a question of the relationship between internal (mental) and external (transpsychic), while, as a mediating link, they proposed, respectively, the set and activity. The question is posed differently in the cultural-historical theory, where mediation is the process of transforming “natural functions” into higher mental processes, in which the “sign” acts as a mediating agent. In any case, the problem of mediation appears to be fundamental. However, the question of a mediator between the psychic and non-psychic world is inseparable from the psychophysical problem, which makes it difficult to reach the real empirical level of analysis. In the light of some considerations by D.N. Uznadze and certain empirical data, an opinion is expressed about the possibility of limiting the area of ​​action of the principle of mediation.
