This paper details and outlines examples of how works of Science Fiction literature can serve as a warning to current and future generations. Eight novels and five themes are examined, with the works spanning a period of nearly two hundred years. These works seem to reflect the various things that scare the majority in society, such as technological reliance and lack of privacy. By citing how the issues in the novels coincide with issues in the real world, the author attempts to show that the various authors are aware of the anxieties of society, and thus work warnings and words of caution into their novels.
