  Recently, “capability theory” has, at the hands of various writers from several disciplines, merged concerns of justice and beneficence. This type of theory focuses on distributions intended to enable persons to reach certain functional levels essential for a flourishing life that is protected by social institutions. The idea is to start with an understanding of health and individual well-being and then to connect that account to basic capabilities for achieving levels of functioning essential to well-being—through, for example, proper nutrition and access to health care. Some core capabilities are bodily health, ability to play, ability to affiliate socially, freedom of movement, and adequate educational level. Amartya Sen and Martha Nussbaum are advocates of a capabilities theory.
