John William Money (8 July 1921 - 7 July 2006) was a psychologist, sexologist and author, specializing in research into sexual identity and biology of gender. He was one of the first scientists to study the psychology of sexual fluidity and how the societal constructs of "gender" affect an individual. More recent academic studies have criticized Money's work in many respects, particularly in regards to his involvement with the sex-reassignment of David Reimer and his eventual suicide. Money's writing has been translated into many languages, and includes around 2,000 articles, books, chapters and reviews.

In this book (Oxford 1988: 116), Money develops a conception of 'bodymind,' as a way for scientists, in developing a science about sexuality, to move on from the platitudes of dichotomy between nature versus nurture, innate versus the acquired, biological versus the social, and psychological versus the physiological. He suggests that all of these capitalize on the ancient, pre-Platonic, pre-biblical conception of body versus the mind, and the physical versus the spiritual. In coining the term "bodymind", in this sense, Money wishes to move beyond these very ingrained principles of our folk or vernacular psychology.  Money also develops here (Oxford 1988: 114-119) a view of "Concepts of Determinism," which, transcultural, transhistorical, and universal, all people have in common, sexologically or otherwise. These include pairbondage, troopbondage, abidance, ycleptance, foredoomance, with these coping strategies: adhibition (engagement), inhibition, explication.  Money suggests that the concept of threshold (Oxford 1988: 115) - the release or inhibition of sexual (or other) behavior - is most useful for sex research as a substitute for any concept of motivation. Moreover, it confers the distinct advantage of having continuity and unity to what would otherwise be a highly disparate and varied field of research. It also allows for the classification of sexual behavior. For Money, the concept of threshold has great value because of the wide spectrum to which it applies. "It allows one to think developmentally or longitudinally, in terms of stages or experiences that are programmed serially, or hierarchically, or cybernetically (i.e. regulated by mutual feedback)." (Oxford 1988: 116)
