Campbell, as a child, became fascinated with Native American culture when his father took him to see the Metropolitan Museum in New York. He soon became versed in numerous aspects of Native American society, primarily in mythology. This led Campbell to a lifelong passion with myth, and its similar, cohesive threads among all human cultures.
Campbell was a student of Carl Jung, just as Jung was before a student of Sigmund Freud. Campbell's work in mythology bridged the seemingly disparate stances of Jung and Freud, and their pivotal debate over the collective unconscious which became an embodiment of the conflicts between Western and Eastern worlds of belief.
Campbell collaborated with Bill Moyers on the PBS series The Power of Myth, which was first broadcast in 1988, the year after Campbell's death in Honolulu. They also jointly authored the book The Power of Myth [ISBN 0385247745] associated with the series.
