Although no universal definition of buen vivir has been attained yet, it has four common constitutive elements: (a) the idea of harmony with nature (including its abiotic components); (b) vindication of the principles and values of marginalized/subordinated peoples; (c) the State as guarantor of the satisfaction of basic needs (such as education, health, food and water), social justice and equality; and (d) democracy. There are also two cross-cutting lines: buen vivir as a critical paradigm of Eurocentric (anthropocentric, capitalist, economistic and universalistic) modernity, and as a new intercultural political project.
