 That all physiological individuals have some kind of autonomous agency is widely recognized and is the intuitive basis for the early systematic formal theorization of biological autonomy undertaken on autopoetic systems by Maturana and Varela (1980) and more recently by Moreno and Mossio (2015). Although such views are typically cast in terms of biological systems rather than individuals, they view the kind of unity of purpose that characterizes both physiological and evolutionary individuals as arising from more general principles governing biological organization, and that organization is important to biological individuality.
