The monograph is devoted to the actual problem of perception of the Alien, which manifests itself in our life at different levels and in different guises. The authors believe that, on the one hand, we ourselves construct the image of the Alien, but, on the other hand, the real Alien interferes with our life and changes it. The book analyzes the broadest aspect of Alien-related issues, from the evolution in popular culture of some fictional beings to the political constructs of multiculturalism. The book will be of interest to historians, culturologists, political scientists and everyone who is interested in modern problems of everyday life.
