This paper examines one of the problem raised by Wittgenstein's discus-sion of rule-following. What is it to grasp a rule (a universal, a pro-perty) given that a rule is individuated by its application to objects which the grasper will never think of? One philosophically tempting solution to this problem is discussed. To grasp a rule is to be disposed to behave in certain ways. The paper shows how this answer resurrects the very problem it was designed to solve and (...) concludes by relating this dia-lectic to Wittgenstein's Quietism. (shrink)
