Abstract

I argue that a practice can only be taken to be one of apparent rule following if it contains a practice of policing moves within the practice. So the existence of an apparently rule-governed practice entails the existence of, what I call, a policing practice. I then argue that this entailment cannot be reconciled with a non-factualist construal of the policing practice. Thus non-factualism about the policing practice is false. Factualism about the policing practice entails realism about rules. So I conclude that we ought to be realists about rules. Finally I distinguish a position which I call ultra-realism about rules and note that this too is a casualty of the view developed here
