Currently, all over the world there is a lot of talk about the crisis of masculinity and what is happening to men. Words about the feminization of men, the weakening of paternity, etc. literally do not leave the pages of mass media. However, often theoretical disputes are not based on a thorough study of the facts, and the fate of Russia is viewed as if it exists on its own, separately from the rest of humanity. In this book, the famous Russian sociologist I. S. Kon tries, first of all, to correctly formulate the problems that have arisen. What does a crisis of masculinity mean? How and why are our ideas about masculinity changing? What global challenges do modern men face, are they able to cope with them, and how are these common problems solved in Russia? The book is based on the results of the latest world sociological, psychological and anthropological research. It contains no technical details, but is designed for thoughtful reading and independent reflection and can be used as a textbook in sociology, gender studies, social anthropology and psychology.
