Continuing their gathering together of related material into mini-portals Science and Theology News have a new section on the concept of emergence and emergent systems. See Science & Theology News – Emergence.
Emergence theorists are not all of one mind, but they do agree that natureâ€™s complex structures â€” from proteins to cells to brains â€” are more than simple combinations of their parts. Rather, they â€œemergedâ€ from lower to higher levels of reality. This means that each level of reality is in some way â€œricherâ€ than what came before.
This fits in nicely with the previous posting (Greenflame: Emergent systems & the church (revisited)) and might provide some background to the paper linked to there.
