Emergenza, poteri causali ed efficacia causal-determinativa

Emergent phenomena can be weak or strong. The former reflect epistemic limits and are ontologically innocent. The latter instantiate properties and powers not had by their components, and they are genuine, novel entities of the world. In this paper, I first show that this view rests upon two metaphysical assumptions: the Eleatic principle, and a power-based view of causation. Then, I suggest that these assumptions should be discussed, rather than passively accepted, and this for three reasons at least: British Emergentism did not require them; they pave the way to relevant objections against the autonomy of emergent phenomena; they provide a too narrow metaphysical frame for emergence.
