The concept of emergence appears in various places within the literature on expertise and expert practice. Here, I examine some of these applications of emergence in the light of two prominent accounts of emergence from the philosophy of science and philosophy of mind. I evaluate these accounts with respect to several specific contexts in which emergence seems to be an appropriate way of characterizing expertise in groups. While it is sometimes assumed that emergent phenomena are in some way inexplicable, the two accounts of emergence I discuss highlight ways in which the concept of emergence relates to specific styles of explanation.
