#concept Play is a voluntary activity of modeling (discovering, exploring, knowing, making) a [[World]] Here , I understand play in the sense of Rene Thom: "In the final analysis, what justifies the player's stance is the fact that the only conceivable way to expose a black box is to play with it. Every great technical and scientific success consists of a black box rendered explicit." I think this 'rendering explicit' is the core of [[worldmaking]]. [[Rene Thom, Play]]
