In this paper, I argue that Bryson’s Oikonomikos is a fascinating example of the oikonomia genre in several different respects. Although the problematic transmission of this Neopythagorean text makes studying it a challenge, such effort is well-rewarded with an elaborate argument which paints the human bodily constitution, the central bodily functions and oikonomic activities as intrinsically linked. Focusing on Bryson’s argument which roots oikonomic behaviour in human biology, I explore the underlying conceptualisation of human nature and contextualise it within relevant (...) philosophical and scientific traditions.
