The present monograph is the outcome of years of researches on media, anthropologic theory and modern philosophy by the team of the sector of analytic anthropology. A broad range of issues and the varying of approaches, which are presented in the book, are integrated by a common subject of mediation. The study covers the following three key points: the first is related to the representation of mediation as a total phenomenon of social life; the second is focused on dealing with the mediator as an actor of multiple and complex relations with Other; and the third reflects mediation as an action leading to the stable or unstable form of relations between the separated elements of any possible whole. Each of the articles, essays, and notes, represented by the monograph, includes these three points that allow to establish the terms for the investigation and to create opportunities for synthesis of the results. The articles of the monograph are conditionally grouped into three chapters: Theory, Programme, and Archive, reflecting the methodology and stylistics of the approach to investigation of mediation.
