 Broad’s concept of emergence is weakly epistemic; his notion is at heart metaphysical: the epistemic predicament that we are in vis-à-vis an emergent property reflects an important metaphysical fact about the property in question, viz. that it is neither identical with nor constituted by the properties and relations of the constituents of the whole in question. Thus Broad’s notion of emergence contrasts with a strongly epistemic notion which, very roughly, says that a property is emergent for a finite epistemic subject when provided with fairly extensive information about the properties and relations of the constituents the subject is still unable logically to infer that property from the information in question although the property in fact is reducible to the features of the constituents.
