Abstract
In this work I bring a conception of language and meaning as a shared institution to bear upon rule-following scepticism, i.e., upon the sceptical problem concerning the semantic determinacy of expressions involving infinite or indefinitely large and open extensions. Such scepticism proceeds from the observation that the extensions of expressions of this kind are not uniquely determined by epistemically accessible facts, to conclude that the expressions in question are indeterminate in point of extension, and that their meaning must consist in their use. ;In the first chapter of this work, I argue that rule-following considerations by themselves do not suffice to establish these conclusions, and that additional premises are needed. I consider both internalist and extensionalist schemes to supplement the sceptical argument. I find such schemes lacking in persuasive support. Chapter 2, in particular, concentrates on Kripke's well known exegesis of Wittgenstein's argument, and on the internalist requirements upon which it is based. ;In Chapter 3, I offer an externalist account of the normative aspect in rule following. On the account I give, the rule one is projecting is determined extensionally by one's position in a community in which his projections would be corrected and evaluated by other members, and from which one has acquired the rule in the first place through a chain of communication, rather than by one's own projections, taken in isolation, which constitute only a partial understanding of the rule in question. This account is not designed to refute scepticism; rather its aim is to account for the normativity of rule-following in ways which do not invoke the internalist requirement upon which rule following scepticism is based
