A detailed description of this book is given at in Russian language since the book is written in this language. The English-language title of the book is "The Jews and their role in our world: personal journey to discovering Jewish identity." The book is not a compilation and analysis of existing religious and scientific conceptions of what constitutes the Jews, or how they get there and what they do. All these concepts are described by the rabbis and religious philosophy scholars in a variety of published books. This book is the result of a life-long journey of the author in an attempt to find an answer to another crucial question of Jewish existence: what the Jews are inspired to do (by God, history, nature, or by their own imagination) in the huge non-Jewish world where they live. The book describes the author's findings, which may be of interest to all intellectual people - Jews and Gentiles.
