In this paper, I examine the problem of "Rule-Following" given by Wittgenstein. In discussing this issue, he considers this problem in terms of "Natural History", and characterizes it as blind obedience. So it seems that his purpose is to reduce Normativity to Natural History. In that case, our knowledge about Rule-Following would disapper. But through the consideration about "agreement in form of life", I'll show that a knowledge about Rule could function as negative operation.
