List of Abbreviations Abstract What does it mean to be a rational language user? What is it to obey linguisticrules? Whatistheproperaccountoflinguisticcompetence? A Fregean answer to these questions would make essential appeal to the notion of sense: we are masters of a language to the extent that we are able to recognise the cognitive value of its expressions; we are rational judges regarding truth-value assignments to the extent that we are sensitive to the ways in which the sense of an expression guidesusinthesemanticevaluationprocess; andasforobeyingrules, it is our ability to respond to how sense directs us, for a particular assertion of a sentence, towards the determination of its truth-value that best exemplies what it is like to follow a linguistic rule. My thesis explores a cluster of closely interrelated issues arising from these questions (whether or not considered from a Fregean per- spective). Accordingly, in tracing the routes of sense my dissertation places itself at the intersection of the philosophy of language, linguistics, philosophy of logic, and meta-ethics—and indeed, I end up agree- ing with Allan Gibbard that the theory of meaning really belongs to meta-ethical reection. Chapter introduces some of the main research questions that I try to address in the rest of the thesis. In chapter I state a number of theses which I take to be the den- ing ones for semanticism. I show that they form a class of jointly incompatible commitments. I choose nonsense as a problem case for compositionality and I argue that it forces the semanticist to aban- don either the learnability or the compositionality constraint. e escape route I adopt, going radically minimalist about content, is in- compatible with another key semanticist thesis, namely, that grasp of meaning is grasp of truth-conditions (robustly conceived). In chapter , I consider the account of atomic meanings given by both the semanticist and the pragmaticist and I conclude that on nei- ther account does interpretation come out as a process of rational ix choice between candidate bearers of content. Again, I suggest the les- son from indeterminacy is that we ought to embrace an ineradicably minimal conception of content. In chapter I turn my attention to the meaning of the logical con- stantsandIarguethatindeterminacyworriesextendtotheveryheart of the compositional machinery. Chapter examines the view that logic is the science of reasoning. Unsurprisingly, I conclude that a defence of this claim requires en- dorsing content-minimalism. In chapter I conclude my dissertation by sketching a radical view of content minimalism and I try to show how it can solve the puzzles I had been considering over the course of the previous chapters. x Acknowledgements e idea (and the title) for this dissertation came to me while reading Dummett (a: ), a short, highly compressed review note on David Bell’s book on Husserl. e crucial question discussed in that note was the relationship between the Fregean notion of sense (for Dummett, an essentially object-directed one) and Husserl’s views re- garding objectual reference. Dummett pointed out that in giving an account of intentionality and meaning, we must do justice to both the intensional (object- independent) and the extensional (object-dependent) mode. e dif- culty is becoming clear as to which mode Fregean Sinn belongs to. In stating his own view of the matter, Dummett said the following (p. ): We must not […] think of a Fregean sense as an intermediate station en route to the referent, as if the thinker aimed at the sense, which then readdressed the thought to the referent. e sense is itself the route; the entire route,
