When is top-down design preferable, and when should we let systems self-organize? --- ### **Resources** - Ilya Prigogine, _Order Out of Chaos_ (1984). - John Holland, _Emergence: From Chaos to Order_ (1998). - Steven Johnson, _Emergence: The Connected Lives of Ants, Brains, Cities, and Software_ (2001).
