In an interdisciplinary approach to assessing the meaning of life, a superordinate, three-part concept is adopted to account for the complexity of life. The meaning of such an overarching concept for an individual is articulated as a narrative fulfilling the criteria of a conceptual belief. We explain how attributing meaning to one’s own life transcends a person’s condition beyond the here-and-now present moment. Thus, believing that one’s own life has meaning serves as a mindset that guides someone to achieve envisioned goals and strive to act accordingly in the social environment. A conclusion is that the subjective meaning of the superordinate concept of life is a conceptual belief that obviates the traditional mind-body dualism.
