Book excerpt: Late 19th century science fiction stories and utopian treatises related to morals and attitudes often focused on economic, sociological and, at times Marxist ideas. More than a century later, science fiction commonly depicts the inherent dangers of capitalism and imperialism. Examining a variety of conflicts from the Civil War through the post-9/11 era, this collection of new essays explores philosophical introspection and futuristic forecasting in science fiction, fantasy, utopian literature and film, with a focus on the warlike nature of humanity.
