Lange married Bernice L. Green on January 14, 1956 while he was still a student at USC. The couple have three children: John, David, and Jennifer.
Lange earned his PhD in 1963 from Princeton University. His dissertation was named: "In defence of ethical naturalism: an examination of certain aspects of naturalistic fallacy, with particular attention to the logic of an open question argument". Lange summed it up in an interview by saying "if one cannot make sense of morality within some sort of satisfying, natural context, then one is likely to end up with no morality, which is less than societally reassuring, or is likely to end up with a competitive plethora of moralities in which ninety-nine percent of the world's population is convinced that the other ninety-nine percent is unclean, stupid, uninformed, vicious, depraved, in need of coercive correction, and such. That too, seems less than reassuring."
Norman's fiction attained popularity in the 1970s and early 1980s with an estimated 6 to 12 million copies sold.
John Norman's Gorean Saga is a long-running series of adventure science fantasy novels, starting in December 1966 with Tarnsman of Gor. The series was put on hold after its twenty-fifth installment, Magicians of Gor, in 1988, when DAW refused to publish its successor, Witness of Gor. After several unsuccessful attempts to find a trade publishing outlet, the series was brought back into print in 2001 with the publication of Witness of Gor. Norman has also produced a separate science fiction series, the Telnarian Histories, plus three other fiction works, five non-fiction works, and a collection of thirty short stories.
According to Norman, his Gor books are science fiction or adventure fantasy works which are also "intellectual, philosophical, and psychological novels". His fiction depicts fantastic worlds where male-dominatedbondage relationships are natural and widely practiced and respected culturally, whereas characteristics of modern society are criticized and philosophical themes are explored, specially from a Nietzschean view.
Although the bondage in his Imaginative Sex guide is directed to sexual practices, the bondage and slavery presented on "Gor" follows along the lines of societal or legal slavery; a common way of life as reflected in ancient Rome and other societies. While the philosophy presented is unquestionably that of male dominance, male characters are themselves occasionally enslaved by powerful females. In an interview with Polygraff magazine, Norman stated that he believes that it is obvious that all societies are based on dominance and hierarchy.
