In The Principles of Mathematics, Bertrand Russell famously puzzled over something he called the unity of the proposition. Echoing Russell, many philosophers have talked over the years about the question or problem of the unity of the proposition. In fact, I believe that there are a number of quite distinct though related questions all of which can plausibly be taken to be questions regarding the unity of propositions. I state three such questions and show how the theory of propositions defended in my recent book The Nature and Structure of Content answers them.

Lots of contextually sensitive expressions appear to have context invariant meanings that do not by themselves suffice to secure semantic values for those expressions in context. For example, suppose I say 1. She is smart. where I do not demonstrate any female, I don’t intend that some female is the semantic value of my use of ‘she’, no female is uniquely salient in the context of utterance, and no female has been under discussion. It would appear in such a case that the context invariant meaning of ‘she’ does not secure a semantic value in context for my use of ‘she’, resulting in infelicity. After all, what would that semantic value in context be? This appears to show that the context invariant meaning of ‘she’ does not by itself secure semantic values in context for it. The class of expressions that are like ‘she’ in this respect is quite large. It arguably includes simple and complex demonstratives, tense, expressions taking implicit arguments, gradable adjectives, quantifiers, ‘only’, possessives, conditionals, modals and more. I call these expressions supplementives to highlight the fact that their context invariant meanings need to be supplemented in context for them to secure semantic values in context. I claim that supplementives differ from each other in the following two ways: 1. The degree to which normal speakers are explicitly aware that the expression is contextually sensitive. 2. The degree to which ordinary speakers are explicitly aware of what sort of semantic value in context the expression takes. I hold the view that semantic values in context for supplementives are fixed by recognizable speaker intentions. However, I argue that given the differences between supplementives with respect to 1 and 2, the intentions fixing the semantic values in context of supplementives that differ with respect to 1 and 2 will themselves be different, while still all being speaker intentions that some entity o be the semantic value of the use of the supplementive in context.

Like many, though of course not all, philosophers, I believe in propositions. I take propositions to be structured, sentence-like entities whose structures are identical to the syntactic structures of the sentences that express them; and I have defended a particular version of such a view of propositions elsewhere. In the present work, I shall assume that the structures of propositions are at least very similar to the structures of the sentences that express them. Further, I shall assume that ordinary names are devices of direct reference and contribute only their bearers to propositions, that n-place predicates contribute n-place properties or relations to propositions, and that verbs of propositional attitude contribute to propositions two-place relations between individuals and propositions. The broad outline of a framework that includes these assumptions is one that I think many, though again not all, philosophers of language find congenial. I am concerned here to investigate and explain, from the standpoint of this framework, a puzzling phenomenon. The explanation I give of the phenomenon could be adapted to fit with frameworks somewhat different from the one adopted here. I adopt the present framework in part simply for definiteness.

Belief in propositions has had a long and distinguished history in analytic philosophy. Three of the founding fathers of analytic philosophy, Gottlob Frege, Bertrand Russell, and G. E. Moore, believed in propositions. Many philosophers since then have shared this belief; and the belief is widely, though certainly not universally, accepted among philosophers today. Among contemporary philosophers who believe in propositions, many, and perhaps even most, take them to be structured entities with individuals, properties, and relations as constituents. For example, the proposition that Glenn loves Tracy has Glenn, the loving relation, and Tracy as constituents. What is it, then, that binds these constituents together and imposes structure on them? And if the proposition that Glenn loves Tracy is distinct from the proposition that Tracy loves Glenn yet both have the same constituents, what is about the way these constituents are structured or bound together that makes them two different propositions? In The Nature and Structure of Content, Jeffrey C. King formulates a detailed account of the metaphysical nature of propositions, and provides fresh answers to the above questions. In addition to explaining what it is that binds together the constituents of structured propositions and imposes structure on them, King deals with some of the standard objections to accounts of propositions: he shows that there is no mystery about what propositions are; that given certain minimal assumptions, it follows that they exist; and that on his approach, we can see how and why propositions manage to have truth conditions and represent the world as being a certain way. The Nature and Structure of Content also contains a detailed account of the nature of tense and modality, and provides a solution to the paradox of analysis. Scholars and students working in the philosophy of mind and language will find this book rewarding reading.

At least since Russell’s influential discussion in The Principles of Mathematics, many philosophers have held there is a problem that they call the problem of the unity of the proposition. In a recent paper, I argued that there is no single problem that alone deserves the epithet the problem of the unity of the proposition. I there distinguished three problems or questions, each of which had some right to be called a problem regarding the unity of the proposition; and I showed how the account of propositions formulated in my book The Nature and Structure of Content [2007 Oxford University Press] solves each of these problems. In the present paper, I take up two of these problems/questions yet again. For I want to consider other accounts of propositions and compare their solutions to these problems, or lack thereof, to mine. I argue that my account provides the best solutions to the unity problems.

A central job for propositions is to be the objects of the attitudes. Propositions are the things we doubt, believe and suppose. Some philosophers have thought that propositions are sets of possible worlds. But many have become convinced that such an account individuates propositions too coarsely. This raises the question of how finely propositions should be individuated. An account of how finely propositions should be individuated on which they are individuated very finely is sketched. Objections to the effect that the account individuates propositions too finely are raised and responses to the objections are provided. It is also shown that theories that try to individuate propositions less finely have serious problems.

This Handbook brings together contributions from leading scholars of constitutional theory, with backgrounds in law, philosophy, and political science. Its 60 chapters not only offer an exceptional survey of the field but also provide a major contribution to it. The book explores three main areas. Firstly, the values upheld by a constitution, including rights, freedom, equality, dignity and well-being. Secondly, the modalities of a constitutional system, such as the separation of powers, democratic representation, and the rule of law. Finally, the institutions through which it operates, both legal and political; including courts, elections, parliaments and international organisations. It also considers the challenges confronting constitutional arrangements from growing inequality, populism, climate change and migration.

Deliberative democratic theory emphasises the importance of informed and reflective discussion and persuasion in political decision-making. The theory has important implications for constitutionalism - and vice versa - as constitutional laws increasingly shape and constrain political decisions. The full range of these implications has not been explored in the political and constitutional literatures to date. This unique Handbook establishes the parameters of the field of deliberative constitutionalism, which bridges deliberative democracy with constitutional theory and practice. Drawing on contributions from world-leading authors, this volume will serve as the international reference point on deliberation as a foundational value in constitutional law, and will be an indispensable resource for scholars, students and practitioners interested in the vital and complex links between democratic deliberation and constitutionalism.
