I achieve this by means of a partly historical investigation into the problem of the unity of the proposition; this is the problem of distinguishing a proposition - the bearer of truth, the complex object or content of a belief or other propositional attitude, and the meaning of a true/false statement - from an „aggregate‟ of its constituent parts. In chapter 1, I assess Bertrand Russell‟s first attempt at a solution, and give a detailed account of why his proposed analysis of a proposition and the sentence expressing it generates a viciously regressive analysis. In chapter 2, I assess Frege‟s approach to the problem, and show that he offers a fundamental insight by way of his approach to analysis which draws an absolute distinction between functions and their argument, and treats concepts as functions to truth-values. Frege has, of course, influenced many contemporary philosophers of language, notably Dummett and Davidson, who have argued that Frege‟s insights offer us a lens thorough which to understand the nature of predication in natural languages. I argue that these proposed revisions of Frege‟s account fall short of an adequate solution to the unity problem. In chapter 3, I present and critically discuss Russell‟s multiple relation theory of judgment and Wittgenstein‟s approach to the unity problem as presented in the Tractatus Logico- Philosophicus and how these may be interpreted as offering a partial advance to the unity problem over the solutions previously considered. Then, in chapter 4, I move on to assess some recent solutions which, influenced by both Russell‟s later theory and Wittgenstein‟s early work, attempt to either solve or expose the question of unity as it struck Russell and Frege as a „pseudo-problem‟. These solutions propose a range of approaches to the „naturalisation‟ of the concept of meaning and the phenomenon of propositional representation. Whilst I take this naturalistic turn to be - at least in some respects - commendable, in chapter 5 I develop an alternative account, focusing how lexical meaning may be investigated independently of its contribution to full propositional (true/false) representation. I show how this reorientation might light the path towards richer accounts of meaning-relevant syntactic structure and lexical content than the rival accounts previously discussed.

He has offered invaluable advice, encouragement and constructive criticism of my work during the five years at which I have been studying as a postgraduate at UEA. He has also been a good friend. I am also very grateful to my many other friends, both students and colleges, here in the philosophy faculty at UEA and in Norwich, which has been a very pleasant place in which to live, work and play over these last few years. I would especially like to thank Oskari Kuusela, Rupert Read, Marie McGinn, Tamara Dobler, Ben Walker, Fiona Roxburgh, Tom Greaves, Odai al Zoubi, and above all, Alun Davies. I am grateful to the Faculty of Arts and Humanities for a three year studentship which provided me with financial support. I have presented my thoughts on matters relating to this thesis at various conferences, workshops and philosophy society meetings over the last few years. Some of those thoughts have survived scrutiny and made their way into the thesis in one form or another. I would like to thank several non-UEA people whose constructive comments during discussions have been especially helpful on such occasions, especially Martin Stockhof, Peter Sullivan, Ariana Betti, Guy Longworth, Peter Hylton, Charles Travis and especially Michael Beaney. I have forgotten to mention many people to whom I owe a debt of gratitude, and to them I apologise. Should any of you be reading this, I shall endeavour to thank you all in person - over a pint, perhaps - in the fullness of time. Finally, I have two special mentions: firstly, I would like to express my heartfelt love and thanks to Joëlle Monod and Tony Summers, my mum and dad, for their unflinching love and support over the last thirty-something years. This thesis is dedicated to them. My second special mention is for Liz McKinnell, for more than I could ever hope to say in so few words. Introduction Spoken words are the symbols of mental experience … As there are in the mind thoughts which do not involve truth or falsity, and also those which must be either true or false, so it is in speech. For truth and falsity imply combination and separation. Nouns and verbs, provided nothing is added, are like thoughts without combination or separation. … By noun we mean a sound significant by convention [and] a verb is always a sign of something said of something else, i.e. of something either predicable of or present in some other thing Aristotle, De Interpretatione, Parts 1-3. Trans. Edghill What distinguishes a proposition, considered as a complex of discrete constituents, from a mere aggregate of those constituents? This is the problem of the unity of the proposition.1 Unity problems do not arise only in the analysis of propositions, of course; given any abstract object, considered as a complex composed of independently specifiable parts, we may ask: how do the elements specifiable under analysis become a whole, a complex unity? One may, of course, think there is no real metaphysical problem here - one might follow Lewis (1991), who, in his discussion of the mereology of classes, appeals to a principle of unrestricted compositionality, proposing that a collection or fusion of things constitutes a mereological unity „no matter how many or how unrelated or disparate in character they may be‟ (ibid: 7). According to Lewis‟s principle, commitment to a mereological fusion of things is nothing over and above a commitment to the things which constitute the collection. However, not all compositions of things should be thought of as „innocent‟ or „automatic‟ fusions in this way. Consider, for example, the case of a fact, supposing it to be a complex of parts. Amongst those facts which obtain in the world there are, let us suppose, the fact that Nina sings and the fact that Frank loves Nina, which are mereological fusions of the simpler parts [Nina, sings] and [Frank, Loves, Nina].2 If we assume a principle as unrestrained as Lewis‟s in this case, this leaves us at a loss to explain why other structured complexes of parts such as [Nina, Frank] and [Loves, Nina, Sings] are not themselves possible facts. This difficulty, arising in the analysis 1 In what follows, I shall use „UP‟, „the unity problem‟ and „the problem of the unity of the proposition‟ interchangeably, except where disambiguation is necessary. 2 I use these examples for expository simplicity. Of course, the fundamental constituents of these putative facts are not Nina, Frank, etc., who are themselves complex things. of facts, generalises to the analysis of any putatively complex whole. The capacity for the constituents of what we take to be complex wholes to enter - or fail to enter - into combination with each other so as to form new objects appears to depend upon some independently specifiable capacity of the possible constituents of the complexes in question. Accounting for the unity of a complex thus appears to demand either that we specify a further combinatorial element or object which serves to bind the remaining constituents together, or that unity arises due to the intrinsic or internal properties of the wholes or their simpler parts.
