Analyzing more than three decades of screen adventure, the authors depict a Star Trek transformed, corresponding to the resurgence of religion in American public discourse. The authors analyze Star Trek's many religious characters, tracing the roots of scientific humanism to more contemporary aspects of religion and spirituality. Through it all, the creators' visionary outlook remains constant: a humanistic faith in free will and the salvific nature of dispassionate scientific inquiry.
