And that’s the reason

“To understand a practice is to come to grasp the reasons that that practice gives you—reasons that are not intelligible from outside the practice. Induction into the rôle of participant in the practice entails induction into the reasons characteristic and definitive of the practice. So by adopting the rôle I learn—and before that, commit myself to learn—to have the reasons. Not necessarily quickly or easily, either; induction into a practice can be, indeed usually is, hard work. By such induction I ‘systematically extend’ my own capacities to achieve the various kinds of excellence; and that means, too, that I systematically extend my own repertoire of reasons.” – Sophie-Grace Chappell, “Rôles and Reasons” (emphasis in original)
