For years, spirituality and finding the meaning of life have been considered essential phenomena in the context of human existence. Zohar introduced the term spiritual intelligence (SI) in 1997, and since that time researchers have been seeking to clarify the concept. Emmons (The psychology of ultimate concerns. Guilford Press, New York, 1999) suggested that SI serves as a potentially significant construct to expand our understanding of the psychological determinants of human functioning. In recent years, several efforts to conceptualize and measure this construct have joined the body of related literature, of which King (Brighter paths to wellbeing: an integrative model of human intelligence and health. Trent University Centre for Health Studies Showcase, pp 12-13, 2008) serves as one notable example. Following, evaluating, and summarizing the theoretical debate regarding the validity of a concept, as it is presented in the literature, has long been understood as a helpful way of extending scholarly dialogue. In this project, I review psychological literature relevant to the debate on the validity of SI as a psychological construct. The literature offers many examples that demonstrate a relation between SI and other phenomena that are important for human functioning-well-being in this. Results of the analysis support theoretical considerations for viewing SI as facilitating the ability to search for the meaning of life and provide directions for future study.
