ABSTRACTA paper in two parts, the first is a critique of the commonly held view among both cognitivist and non-cognitivist sport philosophers that conscious mental representation of knowledge that is a necessary condition for skill acquisition. The second is a defense of a necessary causal condition for skill acquisition, a necessary causal condition that is mimetic, physically embodied, and socially embedded. To make my case I rely throughout on a common thought experiment in and beyond the philosophy of sport literature, (...) the seminal work of Kuhn and Quine counter the representational theory of knowledge, and recent argument in the philosophy of sport related to neurophysiology, cognition, and intentionality. Ultimately I conclude that the failure of a necessary representational condition and its replacement by a necessary casual condition in skill acquisition jeopardizes much of what has been said in the philosophy of sport about not just skill acquisition but the more popular topic of high-level skill. It does, because it challenges the assumption that there is some necessary baseline knowledge that which, according to cognitivists, is brought forward in some way into highly skillful performance or, according to non-cognitivists, is somehow left behind or subsumed into a background in highly skillful performance.
