 Certain phenomena and theoretical considerations motivating some contemporary theorists to endorse a strong emergentist construal of those phenomena. (It bears emphasis that strong emergentists typically also suppose that some interesting organized behavior is more plausibly understood either reductively or as weakly emergent: their strong emergentism is piecemeal.) This final section summarizes those phenomena and considers in general terms the different ways strong and weak emergentists might go about treating them.
