In this article we aim to see how far one can get in defending the identity thesis without challenging the inference from conceivability to possibility. Our defence consists of a dilemma for the modal argument. Either “pain” is rigid or it is not. If it is not rigid, then a key premise of the modal argument can be rejected. If it is rigid, the most plausible semantic account treats “pain” as a natural-kind term that refers to its causal or historical origin, namely, C-fibre stimulation. It follows that any phenomenon that is not C-fibre stimulation is not pain, even if it is qualitatively similar to pain. This means there could be phenomena that feel like pain but are not pain since they are not C-fibre stimulation. These possible phenomena can be used to explain away the apparent conceivability of pain without C-fibre stimulation. On either horn of the dilemma, the identity theorist has ample resources to respond to Kripke's argument, even without wandering into the contentious territory of conceivability and possibility.

In 1913 Wittgenstein raised an objection to Russell’s multiple relation theory of judgment that eventually led Russell to abandon his theory. As he put it in the Tractatus, the objection was that “the correct explanation of the form of the proposition, ‘A makes the judgement p’, must show that it is impossible for a judgement to be a piece of nonsense. (Russell’s theory does not satisfy this requirement,” (5.5422). This objection has been widely interpreted to concern type restrictions on the constituents of judgment. I argue that this interpretation is mistaken and that Wittgenstein’s objection is in fact a form of the problem of the unity of the proposition.

The problem of the source of necessity is the problem of explaining what makes necessary truths necessarily true. Simon Blackburn has presented a dilemma intended to show that any reductive, realist account of the source of necessity is bound to fail. Although Blackburn's dilemma faces serious problems, reflection on the form of explanations of necessities reveals that a revised dilemma succeeds in defeating any reductive account of the source of necessity. The lesson is that necessity is metaphysically primitive and irreducible.

All too often when philosophers talk and write about sentences they have in mind only indicative sentences, that is, sentences that are true or false and that are normally used in the performance of assertions. When interrogative sentences are mentioned at all it is usually either in the form of a gesture toward some extension of the account of indicatives or an acknowledgment of the limitations of such an account. For example, in the final two sentences of his influential paper “Truth and Meaning” (1967) Donald Davidson remarks.

Some of the most interesting recent work in philosophy of language and metaphysics is focused on questions about propositions, the abstract, truth-bearing contents of sentences and beliefs. The aim of this guide is to give instructors and students a road map for some significant work on propositions since the mid-1990s. This work falls roughly into two areas: challenges to the existence of propositions and theories about the nature and structure of propositions. The former includes both a widely discussed puzzle about propositional designators as well as direct and indirect arguments against the existence of propositions. The latter is dominated by what is currently the central debate about the metaphysics of propositions, i.e. whether they are structured, composite entities or unstructured ontological simples. This issue has eclipsed older debates about whether propositions can be identified with sets of possible worlds or other kinds of sentence intensions. Author Recommends 1. Soames, Scott.

Oxford: Oxford University Press, 1988. 197–239. Essential groundwork for more recent work on propositions. Soames gives a careful and exacting presentation of the case against identifying propositions with sets of possible worlds or other truth-supporting circumstances. Also contains a detailed statement of the Russellian conception of propositions on which propositions are ordered sets of objects, properties and relations. 2. King, Jeffrey. 'Designating Propositions.' The Philosophical Review 111 (2002): 341–71. Sometimes substituting a definite description for a corresponding 'that'-clause can lead to bizarre changes in truth-conditions: compare 'Bill fears that Hillary will be president' with 'Bill fears the proposition that Hillary will be president'. This puzzle about propositional designators threatens the relational analysis of propositional attitude reports, the view that 'believes' expresses a relation to the proposition designated by its 'that'-clause, and thereby poses an indirect threat to the existence of propositions. King's solution posits an ambiguity in verbs like 'fear' that embed both 'that'-clauses and definite descriptions. 3. Jubien, Michael. 'Propositions and the Objects of Thought.' Philosophical Studies 104 (2001): 47–62. A direct attack on the existence of propositions. Jubien deploys an analogue of the problem that Paul Benacerraf raised for set-theoretical reductions of numbers against metaphysical reductions of propositions. Just as numbers can be reduced to sets in many different ways, any reduction of propositions brings with it equally good variants, thus making any such reduction arbitrary and unmotivated. The only alternative is to treat propositions as abstract metaphysical primitives. As Jubien argues, however, abstract primitive entities are incapable of doing what propositions must do, i.e. represent objects and states of affairs on their own, without the input of thinking subjects. The upshot is the propositions cannot be reduced and they cannot be primitive, and so they must not exist. 4. Hanks, Peter. 'How Wittgenstein Defeated Russell's Multiple Relation Theory of Judgment.' Synthese 154 (2007): 121–46. Scepticism about propositions has recently led some philosophers, Jubien included, to resuscitate Russell's multiple relation theory of judgment, the idea that judgment is a many-place relation to objects, properties and relations. This paper explains why Russell himself abandoned that theory, and why the theory is still refuted by an objection due to Wittgenstein. 5. Hofweber, Thomas. 'Inexpressible Properties and Propositions.' Oxford Studies in Metaphysics . 2 vols. Ed. D. Zimmerman. Oxford: Oxford University Press, 2006. 155–206. An indirect attack on the existence of propositions. Hofweber argues that sentences like 'Bill believes something that Hillary asserted' do not commit us to the existence of propositions. His view is that propositional quantification is an instance of what he calls 'internal' or 'inferential role' quantification, a kind of quantification that carries no ontological implications. 6. Schiffer, Stephen. The Things We Mean . Oxford: Oxford University Press, 2003. esp. chs 1–2. Schiffer defends his theory of pleonastic propositions, on which propositions are unstructured, have no parts, and are very finely grained. 7. Bealer, George. 'Propositions.' Mind 107 (1998): 1–32. Bealer defends his algebraic theory of propositions, which, like Schiffer's pleonastic account, treats propositions as unstructured metaphysical simples. 8. King, Jeffrey. The Nature of and Structure of Content . Oxford: Oxford University Press, 2007. The best developed current theory of the structure in structured propositions. King identifies propositions with certain kinds of facts in which objects, properties and relations are bound together by amalgams of syntactic and semantic relations. 9. Hanks, Peter.

Why does identifying propositions with sentence intensions, e.g. sets of possible worlds, 'require the attitudes to have a particular sort of closure under logical consequence, which they clearly don't have' (Mark Richard)? 2. How does the difference between (a) and (b) pose a threat to the existence of propositions? (a) Bill fears that Hillary will be president. (b) Bill fears the proposition that Hillary will be president. 3. What is the Benacerraf problem for metaphysical reductions of propositions? 4. Why must a proposition represent 'on its own cuff' (Michael Jubien)? Why is this a problem for the view that propositions are primitive abstract entities? 5. What does it mean to say that propositions are structured ? Give two different accounts of what propositional structure might be.

Although the terms ‘poles’, ‘bipolar’, and ‘bipolarity’ do not appear in the Tractatus, it is widely held that Wittgenstein maintained his commitment to bipolarity in the Tractatus. As it is usually understood, the principle of bipolarity is that every proposition must be capable of being true and capable of being false, which rules out propositions that are necessarily true or necessarily false. Here I argue that Wittgenstein was committed to bipolarity in the Tractatus, but getting a clear view of this commitment requires a different understanding of bipolarity. Properly understood, bipolarity is the view that every proposition represents two possible states of affairs, one positive and the other negative. Of course, in the case of elementary propositions, the sense of a proposition is only the positive state of affairs. There is thus an asymmetry between what a proposition represents, its true-false poles, and what it says, its sense. In this paper I show how Wittgenstein accounted for this asymmetry in Notes on Logic and I consider two ways he might have accounted for it in the Tractatus.

In this short, clear and engaging book, Neil Feit defends the unorthodox view that the contents of beliefs and other cognitive attitudes are properties, and not, as is usually held, propositions. The core of his argument has to do with de se beliefs, beliefs about the self. Based on examples and arguments due to Perry , Lewis and Chisholm , along with considerations about internalism and physicalism, Feit offers a battery of arguments for the conclusion that the contents of de se beliefs cannot be propositions and therefore must be properties. For reasons of uniformity and simplicity Feit then extends this conclusion to all beliefs. So, according to Feit, the content of the de se belief that I am a philosopher is the property of being a philosopher, and my having this belief consists in my self-ascribing this property. For de dicto beliefs, believing that p is self-ascribing the property of being such that p, and for de re beliefs, believing that x is F is self-ascribing the property of bearing some relation of acquaintance R to something that is F. For example, to have the de dicto belief that …

In Hanks I defend a theory of propositions that locates the source of propositional unity in acts of predication that people perform in thought and speech. On my account, these acts of predication are judgmental or assertoric in character, and they commit the speaker to things being the way they are represented to be in the act of predication. This leads to a problem about negations, disjunctions, conditionals, and other kinds of embeddings. When you assert that a is F or b is G you do not assert that a is F, nor do you commit yourself to a’s being F. According to my theory, however, in uttering the disjunction you predicate F of a. What is going on? I account for these cases using the concept of cancellation. In uttering the disjunction, the act of predicating F of a is cancelled, and when an act of predication is cancelled it does not count as an assertion and does not commit the speaker to anything. But what is it for an act of predication to be cancelled? One immediate concern is that cancelled predication won’t provide a unified proposition to be the input to disjunction. In this paper I answer this and related objections by explaining and defending my concept of cancellation.

As Merricks shows, combining these views leads to an inexplicable coincidence between what a proposition represents and its constituents. Suppose that it is a primitive and unanalysable fact that the proposition that p represents Russell as being a philosopher. Suppose also that p has Russell and the property of being a philosopher as constituents. What is the relationship between these two facts? The latter cannot explain the...

In 1910 Bertrand Russell abandoned the theory of propositions that he advocated in 1903 in The Principles of Mathematics because of the problem of the unity of the proposition. This is the problem of explaining how the constituents of a proposition are bound together into a unified, representational whole. This problem has largely been ignored by contemporary advocates of Russellian propositions. I argue that this problem is the result of the Fregean distinction between content and force, the arguments for the content-force distinction are inconclusive and there is independent linguistic evidence against the content-force distinction. For these reasons I think that Frege's distinction between content and force should be abandoned; this is the main negative conclusion of the dissertation. ;The main positive component of the dissertation is an account of structured propositions that individuates propositions in terms of force or mood. On the account I defend, propositions are types of representational actions or states. The proposition expressed by 'Jones loves Smith', for example, is a type of representational state, tokens of which are particular assertions that Jones loves Smith or belief-states that Jones loves Smith. The proposition expressed by 'Does Jones love Smith?', on the other hand, is a type of interrogative action or state, tokens of which are instances of asking whether Jones loves Smith or wondering whether Jones loves Smith. This account solves the problem of the unity of proposition by locating the unifying element in a proposition in an act of the subject. In addition, this account provides an empirical foundation for semantics. A semantic theory, on this view, is a theory of what speakers do with sentences in contexts. To say that a sentence S expresses a proposition p in context c is to record a fact about the literal and direct illocutionary act that could be performed using S in c.
