I hope to clarify and explicate an account of how a creature comes to be brought into the space of reasons – that is, comes to take its place as a rational agent in social practices. My ultimate interest, however, is with a tension apparently generated by the emphasis on training coupled with this attack on cognitivism. If one’s coming to maturity depends on one being embedded in a practice, so that one comes to adopt, with ‘comfortable certainty’, the common (...) ground of that practice’s language games, then there seems to be no position from which to frame a critique of a practice.
