Underground Man

'Underground Man' is a science-fiction novel written by Gabriel Tarde. It is a post-apocalyptic story of an Earth destroyed by a new Ice Age. Humanity must rebuild a new civilization underground. The choice is made to lay the foundation of their utopia on music and art. Tarde is best-remembered today for being a sociologist, criminologist and social psychologist who conceived sociology as based on small psychological interactions among individuals (much as if it were chemistry), the fundamental forces being imitation and innovation.
