Concepts like flourishing, well-being, health, and happiness are of increasing interest across many fields, from psychology and medicine to politics and economics. However, these terms are used in diverse and contested ways, which makes it hard to find common ground and understanding. To attempt to help remedy the confusion, this paper offers an overarching conceptual “map” within which these concepts can be situated, thereby providing a common language and framework for their consideration. Moreover, while the overall configuration of this map is conceptually and logically stable, its specific elements are more flexible, particularly in terms of scalable granularity (allowing fine-grained differentiation of internal regions) and epistemological openness (allowing revisions in light of gains in knowledge). As such, the map can be adapted to suit different fields, and updated to accommodate advances in understanding. To that end, we clarify topics of investigation that are still in need of development, providing a roadmap for future research.
