Is positive thinking really so healthy that, as Martin Seligman (2000) and Mihaly Csikszentmihalyi passionately thus argued, we believe that a psychology of positive human functioning will arise, which achieves a scientific understanding and effective interventions to build thriving individuals, families, and communities ? This optimistic view on positive thinking for health can be contrasted with an opposing view by Barbara Ehrenreich (2009), who extensively critiqued ‘positive psychology’ and showed how obsessive positive thinking impedes productive action, causes delusional assessments of situations, and people are then blamed for not visualising hard enough and thus ‘attracting’ failure even in situations when ‘masses of lives were lost’. (WK 2013; R Byrne 2006) Contrary to these opposing views (and other ones as will be discussed in the book), health care (in relation to mental health and physical health in the context of mind and body) are neither possible (or impossible) nor desirable (or undesirable) to the extent that the respective ideologues (on different sides) would like us to believe. Surely, this questioning of the opposing views on health care does not suggest that the study of health care is worthless, or that those fields (related to health care) like medicine, chiropractic, health system, dentistry, health info tech, nursing, psychiatrics, clinical psychology, occupational therapy, pharmacy, allied health, and so on are unimportant. Needless to say, neither of these extreme views is reasonable. Instead, this book offers an alternative (better) way to understand the future of health care, especially in the dialectic relationships between mental health and physical health in the context of mind and body – while learning from different approaches in the literature but without favouring any one of them (nor integrating them, since they are not necessarily compatible with each other). More specifically, this book offers a new theory (that is, the interconnected theory of health care) to go beyond the existing approaches in a novel way and is organised in four chapters.
