Semantic Indeterminacy and Scientific Realism are perhaps the two most ubiquitous and influential doctrines of the Quinean corpus. My concern is to argue against neither in isolation, but against their joint compatibility. Scientific Realism, I argue, when understood as Quine's realistic attitude toward the posits of physical theory, is essentially intentional in character. Thus, Realism requires Intentionality. In Section 1, I provide some necessary exegesis. In Section 2, I attempt to show how this Realism/Intentionality connection arises, surprisingly, within (...) Quine's own mature work to create a tension in his views which he does not himself resolve. In Section 3, I examine the source of the Realism/Intentionality connection more deeply, and respond to possible Quinean objections to my account. In Section 4, I consider the consequences of the connection for various debates in recent analytic philosophy. (shrink)

Is it possible to maintain classical logic, stay close to classical semantics, and yet accept that language might be semantically indeterminate? The article gives an affirmative answer by Ramsifying classical semantics, which yields a new semantic theory that remains much closer to classical semantics than supervaluationism but which at the same time avoids the problematic classical presupposition of semantic determinacy. The resulting Ramsey semantics is developed in detail, it is shown to supply a classical concept of truth and (...) to fully support the rules and metarules of classical logic, and it is applied to vague terms as well as to theoretical or open-ended terms from mathematics and science. The theory also demonstrates how diachronic or synchronic interpretational continuity across languages is compatible with semantic indeterminacy. (shrink)

Some critics believe Quine's semantic indeterminacy (indeterminacy of radical translation at home as well as abroad) thesis is true, but innocent, since it is just scientific underdetermination in linguistics. The Quinean reply is that in scientific underdetermination cases there are facts of the matter making claims true or false (whether knowable or not), whereas in semantic indeterminacy cases there simply are not. The critics' rejoinder that there are such facts, studied in linguistics, is met by (...) the final reply that linguistics either on the whole or in part is riddled with appeals to "meanings" and is, thereby, as suspect as analyticity and radical translation. I recommend "saving"(?) linguistics by holding that it is permanently entangled in epistemology. Finally, the argument the critics should have made concerns paralleling semantic indeterminacy to indeterminacies in current quantum mechanics. (shrink)

The analysis of the derogatory aspect of slurs has recently aroused interest among philosophers of language. A puzzling element of it is its erratic behaviour in embeddings, for instance negation or belief reports. The derogatory aspect seems sometimes to “scope out” from the embedding to the context of utterance, while at other times it seems to interact with the linguistic constructions in which the slur is implanted. I argue that slurs force us to maintain a kind of semantic (...) class='Hi'>indeterminacy which, to my knowledge, has passed largely unnoticed in philosophy of language. (shrink)

Discussions of “indeterminacy” customarily distinguish two putative types: semantic indeterminacy (SI)—indeterminacy that’s somehow the product of the semantics of our words/concepts—and metaphysical indeterminacy (MI)—indeterminacy that exists as a mind/language-independent feature of reality itself. A popular and influential thought among philosophers is that all indeterminacy must be SI. In this paper we challenge this thought. Our challenge is guided by the question: What, exactly, does it take for a case of indeterminacy to count (...) as SI? We argue that the only satisfactory answer to this question must take SI to be grounded in a more basic type of MI. We conclude that SI cannot be made sense of without implicating MI. If there’s any indeterminacy, there must be indeterminacy in the world itself. (shrink)

The teleosemantic indeterminacy problem has generated much discussion but no consensus. One possible solution is to accept indeterminacy as a real feature of some representations. I call this view “indeterminacy realism.” In this paper, I argue that indeterminacy realism should be treated as a serious option. By drawing an analogy with vagueness, I try to show that accepting the reality of indeterminacy would not be catastrophic for teleosemantics. I further argue that there are positive reasons (...) to endorse indeterminacy realism. I end the paper by arguing that indeterminacy realism need not generalize viciously to the case of propositional attitudes. (shrink)

Quantification into modal contexts depends on cross-Identifications of individuals between possible worlds, Which in turn depends on the structure and interrelations of these worlds. There is hence no guarantee that cross-Identification always succeeds. It will fail for the worlds needed for realistic applications of logical modalities, Partly vindicating quine's criticism of them. In general, World lines of individuals cannot always be extended from a world to others.

Statements about the future are central in everyday conversation and reasoning. How should we understand their meaning? The received view among philosophers treats will as a tense: in ‘Cynthia will pass her exam’, will shifts the reference time forward. Linguists, however, have produced substantial evidence for the view that will is a modal, on a par with must and would. The different accounts are designed to satisfy different theoretical constraints, apparently pulling in opposite directions. We show that these constraints are (...) jointly satisfied by a novel modal account of will. On this account, will is a modal but doesn't work as a quantifier over worlds. Rather, the meaning of will involves a selection function similar to the one used by Stalnaker in his semantics for conditionals. The resulting theory yields a plausible semantics and logic for will and vindicates our intuitive views about the attitudes that rational agents should have towards future-directed contents.

Possibility semantics offers an elegant framework for a semantic analysis of modal logic that does not recruit fully determinate entities such as possible worlds. The present papers considers the application of possibility semantics to the modeling of the indeterminacy of the future. Interesting theoretical problems arise in connection to the addition of object-language determinacy operator. We argue that adding a two-dimensional layer to possibility semantics can help solve these problems. The resulting system assigns to the two-dimensional determinacy operator (...) a well-known logic (coinciding with the logic of universal modalities under global consequence). The paper concludes with some preliminary inroads into the question of how to distinguish two-dimensional possibility semantics from the more established branching framework. (shrink)

In "The Domino Theory" Professor Katz's general thesis is that the arguments against intensionalism advanced in the last four decades are arranged like so many dominos, since they all rest upon Quine's arguments against the analytic-synthetic distinction in "Two Dogmas of Empiricism". If this is the case, then they are all vitiated if Quine's original arguments are unsatisfactory, and fall like so many dominos. I propose to accept, if only for the sake of argument, that all the other critiques of (...) intensionalism which Katz mentions do ultimately depend upon the acceptance of Quine's original strictures, although I will express some doubt about this in the case of the indeterminacy of translation thesis. In this paper I will concentrate on Katz's argument against the first Quinian domino. (shrink)

Semantic analysis of contemporary philosophical inquiry is the core problem, and Quine is undoubtedly in the twentieth century conducted to explore the semantic engineering裡arduous, the most influential of modern thinkers. However, although the impact of Quine's great, he semantics regardless of the stance taken by the natural person has not yet been fully satisfied instruction understanding. On the one hand, the based on Quine's controversial idea of the uncertainty, scholars widely believe that regardless Quine's stance is a natural (...) suspicion regardless of extreme stance: the meaning of the word does not exist. On the other hand, Quine in the construction regardless of its license, but to take a natural tendency to analyze the nature of the so-called "stimulus word meaning" future language sentences as the core foundation of semantics. Thus, Quine's semantic natural stance regardless what is a semantic canceled regardless, have a language or meaning regardless of the orientation of some, not very clear. This paper has two purposes: First, the author regardless above, Quine's natural regardless stance in a number of philosophers to cancel regardless positioning, is the station does not live foot stance; Second, in the text, based on Quine's natural regardless stance can be is portrayed as some kind of weaker version of about regardless, and this stance is more feasible. The investigation of linguistic meaning has been central in contemporary analytic philosophy. Quine is undoubtedly one of the most influential thinkers in the 20 century in this daunting inquiry. Despite his enormous influence, however, Quine's naturalistic perspective on meaning has not been properly understood. On the one hand, Quine's view, presented in the controversial indeterminacy thesis, is widely taken as a radical form of skepticism, namely, meaning does not exist. On the other hand, Quine invokes and heavily relies on the notion of disposition to analyze the idea of ​​stimulus meaning, which lies at the heart of Quine's discussion of linguistic meaning. It does not seem entirely clear whether Quine attempts to eliminate meaning, or to naturalize meaning by reducing it to dispositions. The aim of this paper is argue for two points. First, construing Quine's position as semantic eliminativism, as many do, Quine's position would be in deep trouble. Second, based on a textual basis, Quine's position can be alternatively construed as a modest form of dispositional reductionism, which is more tenable. (shrink)

Indeterminacy in its various forms has been the focus of a great deal of philosophical attention in recent years. Much of this discussion has focused on the status of vague predicates such as ‘tall’, ‘bald’, and ‘heap’. It is determinately the case that a seven-foot person is tall and that a five-foot person is not tall. However, it seems difficult to pick out any determinate height at which someone becomes tall. How best to account for this phenomenon is, of (...) course, a controversial matter. For example, some (such as Sorensen (2001) and Williamson (2002)) maintain that there is a precise height at which someone becomes tall and such apparent cases of indeterminacy merely reflects our ignorance of this fact. Others maintain that there is some genuine – and not merely epistemic – indeterminacy present is such cases and offer various accounts of how best to account for it. Supervaluationists (such as Keefe (2008)), for example, claim that the indeterminacy with respect to vague terms lies in their not having a single definite extension. Rather, each term is associated with a range of possible precise extensions or precisifications such that it is semantically unsettled which is the correct extension. One precisification of ‘tall’ might allow that anyone over five feet ten inches is tall, whereas another would only allow those over six foot to qualify; but no precisification will take someone who is five foot to be tall, and someone who is seven foot will count as tall on all precisifications. Thus – while someone who is seven foot will be determinately tall and someone who is five foot determinately not so – it will be indeterminate whether someone who stands at five foot eleven inches is tall. -/- Yet, it is important to stress that putative cases of indeterminacy are not limited to vague predicates of this kind. Philosophers have invoked indeterminacy in discussions of topics as diverse as moral responsibility (Bernstein (forthcoming)), identity over time (Williams (2014)), and the status of the future (Barnes and Cameron (2009)). In this paper, we focus on two areas where discussion of various kinds of indeterminacy has been commonplace: physics and fiction. We propose a new model for understanding indeterminacy across these domains and argue that it has some notable advantages when compared to earlier accounts. Treating physics and fiction cases univocally also indicates an interesting connection between indeterminacy in these two areas. (shrink)

Metasemantics is the metaphysics of semantic endowment: it asks how expressions become endowed with their semantic significance. Assuming that semantics is of the usual truth-conditional sort, metasemantics asks after the determinants of expressions’ distinctive contributions to truth-conditions. There are two widely divergent general approaches to the metasemantic project. Some theories – “productivist” ones such as causal theories or intention-based theories – emphasize conditions of production or employment of the items semantically endowed. Other metasemantic theories – “interpretationist” ones – (...) emphasize conditions of interpretive consumption or reception of such items. The book aims to articulate a set of considerations that favour metasemantic productivism over metasemantic interpretationism, to reconcile a general productivist metasemantic approach with contemporary truth-conditional semantics, and to apply the approach to more specialized case studies in the philosophy of language broadly construed. Finally, a major concern in contemporary philosophy of language after Quine is semantic indeterminacy, the worry that there is no fact of the matter as to the semantic significance of our words. The book articulates a distinctly metasemantic strategy to counter the worry. It is shown how the present approach delivers a more successful response to semantic indeterminacy than extant alternatives, a response that emphasizes the priority of reference over truth, which is both intuitively compelling and theoretically motivated.

In this book I examine various forms of indeterminacy in the law and scrutinize (i.a. by way of game theoretical models) the conditions under which they can be strategically used. In particular, I analyze the advantages and disadvantages of indeterminacy in the wording of laws, contracts, and verdicts. Legal texts are particularly interesting insofar as they address a heterogeneous audience, are applied in a variety of unforeseeable circumstances and must, at the same time, lay down clear and unambiguous (...) standards. I argue for the claim that semantic vagueness is less relevant than commonly supposed in the debate, while other forms of indeterminacy (in particular, polysemy and standard-relativity) are underrated or altogether ignored. This misconception is, as I argue, due to a systematic confusion between semantic vagueness and these forms of indeterminacy. Once it is resolved, the value of indeterminacy can be clearly shown.

This paper defends the idea that there might be vagueness or indeterminacy in the world itself--as opposed to merely in our representations of the world--against the charges of incoherence and unintelligibility. First we consider the idea that the world might contain vague properties and relations ; we show that this idea is already implied by certain well-understood views concerning the semantics of vague predicates (most notably the fuzzy view). Next we consider the idea that the world might contain vague (...) objects ; we argue that an object is indeterminate in a certain respect (colour, size, etc.) just in case it is a borderline case of a maximally specific colour (size, etc.) property. Finally we consider the idea that the world as a whole might be indeterminate; we argue that the world is indeterminate just in case it lacks a determinate division into determinate objects.

This paper constructs a model of metaphysical indeterminacy that can accommodate a kind of ‘deep’ worldly indeterminacy that arguably arises in quantum mechanics via the Kochen-Specker theorem, and that is incompatible with prominent theories of metaphysical indeterminacy such as that in Barnes and Williams (2011). We construct a variant of Barnes and Williams's theory that avoids this problem. Our version builds on situation semantics and uses incomplete, local situations rather than possible worlds to build a model. We (...) evaluate the resulting theory and contrast it with similar alternatives, concluding that our model successfully captures deep indeterminacy. (shrink)

This paper argues that several sorts of metaphysical and semantic indeterminacy afflict the causal relation. If, as it is plausible to hold, there is a relationship between causation and moral responsibility, then indeterminacy in the causal relation results in indeterminacy of moral responsibility more generally.

An influential theory has it that metaphysical indeterminacy occurs just when reality can be made completely precise in multiple ways. That characterization is formulated by employing the modal apparatus of ersatz possible worlds. As quantum physics taught us, reality cannot be made completely precise. I meet the challenge by providing an alternative theory which preserves the use of ersatz worlds but rejects the precisificational view of metaphysical indeterminacy. The upshot of the proposed theory is that it is metaphysically (...) indeterminate whether p just in case it is neither true nor false that p, and no terms in ‘p’ are semantically defective. In other words, metaphysical indeterminacy arises when the world cannot be adequately described by a complete set of sentences defined in a semantically nondefective language. Moreover, the present theory provides a reductive analysis of metaphysical indeterminacy, unlike its influential predecessor. Finally, I argue that any adequate logic of a language with an indeterminate subject matter is neither compositional nor bivalent. (shrink)

This article considers a Quine-Dennett style of argument from the indeterminacy of intentional content against the reducibility of mental states to neurological states. The most compelling version of such an argument, I suggest, is one that exploits a semantic anti-realist notion of truth; this holds out the promise of a relatively sophisticated story about the respects in which mental state attributions may be true or false of physical systems, without those states themselves being physical states.

Jerry Fodor has charged that Fred Dretske's account of content suffers from indeterminacy to the extent that we should reject it in favor of Fodor‘s own account. In this paper, we ask what the problem of indeterminacy really is; we distinguish a relatively minor problem we call ‘looseness of fit’ from a major problem of failing to show how to point to what is not there. We sketch Dretske's account of content and how it is supposed to solve (...) the major problem. After presenting Fodor's challenge as the claim that Dretske has failed to solve the major problem, we articulate a response available to Dretske. Although we do not think the response is ultimately successful, we argue that it is every bit as good as the response Fodor has offered to a similar challenge, in his so-called ‘mixed theory.’ The upshot is this: despite advertisements to the contrary, Fodor's theory, in its mixed version, offers no real advantages over Dretske's regarding the serious problem of indeterminacy.

W. V. O. Quine's contention that translation is indeterminate has been among the most widely discussed and controversial theses in modern analytical philosophy. This chapter offers some initial reflections on the content and implications of the indeterminacy thesis, and of the presuppositions that Quine makes in treating it as a stepping‐stone to semantic irrealism. It distinguishes Quine's two principal arguments for the thesis: the famous 'gavagai' argument of Word and Object, and the argument from the underdetermination of empirical (...) theory by data emphasized in 'On the reasons for the indeterminacy of translation', and lays out the essentials of the former argument. The chapter assesses the cogency of Evans's objections, and lays‐out certain basic distinctions and implications of the second and more radical argument. The translation of theoretical terms in the native scientists' language can be no more indeterminate than is the selection of an empirically adequate theory of those data. (shrink)

An attractive approach to the semantic paradoxes holds that cases of semantic pathology give rise to indeterminacy. What attitude should a rational agent have toward a proposition that it takes to be indeterminate in this sense? Orthodoxy holds that rationality requires that an agent disbelieve such a proposition. I argue that a rational agent should be such that it is indeterminate whether it believes the proposition in question. For rational agents, indeterminacy in the objects of their (...) attitudes will filter up to the attitudes themselves. (shrink)

According to the form of logical pluralism elaborated by Beall and Restall there is more than one relation of logical consequence. Since they take the relation of logical consequence to reside at the very heart of a logical system, different relations of logical consequence yield different logics. In this paper, we are especially interested in understanding what are the consequences of endorsing Beall and Restall’s version of logical pluralism vis-à-vis the normative guidance that logic is taken to provide to reasoners. (...) In particular, the aim of this paper is threefold. First, in Sections 2 and 3, we offer an exegesis of Beall and Restall’s logical pluralism as a thesis of semantic indeterminacy of our concept of logical consequence – i.e. understood as indeterminacy logical pluralism. Second, in Sections 4 and 5, we elaborate and critically scrutinize three models of semantic indeterminacy that we think are fit to capture Beall and Restall’s indeterminacy logical pluralism. Third, in Section 6, following Beall and Restall’s assumption that the notion of logical consequence has normative significance for deductive reasoning, we raise a series of normative problems for indeterminacy logical pluralism. The overall conclusion that we aim to establish is that Beall and Restall’s indeterminate logical pluralism cannot offer an adequate account of the normative guidance that logic is taken to provide us with in ordinary contexts of reasoning.

This paper will appeal a recent argument for the indeterminacy of translation to show not that meaning is indeterminate, but rather that assertion cannot be explained in terms of an independent grasp of the concept of truth. In particular, it will argue that if we try to explain assertion in terms of truth rather than vice versa, we ultimately will not be able to make sense of the difference between assertion and denial. This problem with such 'semantic' accounts (...) of assertion then illustrates why we need not worry about the purported argument for indeterminacy. (shrink)

The semantics of our event talk is a complex affair. What is it that we are talking about when we speak of Brutus’s stabbing of Caesar? Exactly where and when did it take place? Was it the same event as the killing of Caesar? Some take questions such as these to be metaphysical questions. I think they are questions of semantics—questions about the way we talk and about what we mean. And I think that this conflict between metaphysic and (...) class='Hi'>semantic concerns is indicative of a “deep indeterminacy” (Bennett’s phrase) in our event concept. We do talk about events; but what events a statement is about is not something that can be inferred from the event names we use; it depends heavily (more heavily than with ordinary material objects) on local context and unprincipled intuitions. This paper illustrates this view in connection with two examples: the phenomenon of vagueness and the dispute over identity statements. (shrink)

This is an old draft of a paper that seeks to find the minimum cognitive/practical role for indeterminacy that we get if we assume a fully classical logic and semantics, but reject epistemicism. The ambition is to connect that classical setting to the framework for rational belief and decision I described in "Decision Making under Indeterminacy".

In Facing the Future, Belnap et al. reject bivalence and propose double time reference semantics to give a pragmatic response to the following assertion problem: how can we make sense of assertions about future events made at a time when the outcomes of those events are not yet determined? John MacFarlane employs the same semantics, now bolstered with a relative-truth predicate, to accommodate the following apparently conflicting intuitions regarding the truth-value of an uttered future contingent: at the moment of utterance, (...) if asked to evaluate the truth-value of the asserted future contingent one has the intuition that the assertion is neither true nor false, yet later, at the moment of the predicted event, one has the intuition that the assertion was, already, either true or false. Both MacFarlane and Belnap assume that assertions of future contingents have complete propositional content – the traditional propositional contents that, according to him ‘are the contents of assertions and beliefs’. This assumption is challenged. (shrink)

A bivalent valuation is snt iff sound (standard PC inference rules take truths only into truths) and non-trivial (not all wffs are assigned the same truth value). Such a valuation is normal iff classically correct for each connective. Carnap knew that there were non-normal snt valuations of PC, and that the gap they revealed between syntax and semantics could be "jumped" as follows. Let $VAL_{snt}$ be the set of snt valuations, and $VAL_{nrm}$ be the set of normal ones. The bottom (...) row in the table for the wedge 'v' is not semantically determined by $VAL_{snt}$ , but if one deletes from $VAL_{snt}$ all those valuations that are not classically correct at the aforementioned row, one jumps straights to $VAL_{nrm}$ and thus to classical semantics. The conjecture we call semantic holism claims that the same thing happens for any semantic indeterminacy in any row in the table of any connective of PC, i.e., to remove it is to jump straight to classical semantics. We show (i) why semantic holism is plausible and (ii) why it is nevertheless false. And (iii) we pose a series of questions concerning the number of possible steps or jumps between the indeterminate semantics given by $VAL_{snt}$ and classical semantics given by $VAL_{nrm}$.

One of the most popular and enduring approaches to indeterminacy phenomena (e.g., vagueness) over the past several decades has been some form or another of supervaluationism. I argue that supervaluationism is inadequate as a model of indeterminacy: There is an entire class of examples of indeterminacy, characterized by a common “branching” structure, that cannot be modeled in the way supervaluationism proposes. I demonstrate my conclusion explicitly with respect to two specific examples—indeterminate personal identity and indeterminate reference—showing how (...) supervaluationism can model neither. Importantly, my arguments apply to both traditional “semantic” and more recent “metaphysical” versions of supervaluationism. (shrink)

It has been argued that non-relativistic quantum mechanics is the best hunting ground for genuine examples of metaphysical indeterminacy. Approaches to metaphysical indeterminacy can be divided into two families: meta-level and object-level accounts. It has been shown :27–245, 2010. https://doi.org/10.1080/00048400903097786; Skow in Philosophical Quarterly 60:851–858, 2010) that the most popular version of the meta-level accounts, namely the metaphysical supervaluationism proposed by Barnes and Williams, fails to deal with quantum indeterminacy. Such a fact has been taken by many (...) as a challenge to adapt supervaluationism to quantum cases. In this paper, I will focus on the very last of these attempts, i.e. the situation semantics account proposed by Darby and Pickup. After having shown where quantum indeterminacy arises and having surveyed the assumptions endorsed by the participants of the debate, I turn to Darby and Pickup’s proposal. I argue that, despite the machinery introduced, their account still fails to account for quantum indeterminacy. After considering some possible counterarguments, I suggest in the conclusion that one can plausibly extend the argument to those meta-level approaches that treat quantum indeterminacy as worldly indecision.

Let the moral question of personal identity be the following: what is the nature of the entities we should focus our prudential concerns and ascriptions of responsibility around? (If indeed we should structure these things around any entities at all.) Let the semantic question of personal identity be the question of what is the nature of the entities that ‘person’ is true of. A naive (in the sense of simple and intuitive) view would have it that the two questions (...) are so intimately connected that the entities we should focus our concerns and ascriptions around are, pretty trivially, the persons. In part, my aim here is to evaluate this naive view. However, I will not actually attempt to give a definite verdict on it. Rather, I will identify the assumptions under which the naive view is true, and discuss how to go about evaluating those assumptions. (shrink)

It is argued that truth value of a sentence containing free variables in a context of use, just as the reference of the free variables concerned, depends on the assumptions and posits given by the context. However, context may under-determine the reference of a free variable and the truth value of sentences in which it occurs. It is argued that in such cases a free variable has indeterminate reference and a sentence in which it occurs may have indeterminate truth value. (...) On letting, say, x be such that \, the sentence ‘Either \ or \’ is true but the sentence ‘\’ has an indeterminate truth value: it is determinate that the variable x refers to either 2 or \, but it is indeterminate which of the two it refers to, as a result ‘\’ has a truth value but its truth value is indeterminate. The semantic indeterminacy is analysed in a ‘radically’ supervaluational semantic framework closely analogous to the treatment of vagueness in McGee and McLaughlin and Smith, which saves bivalence, the T-schema and the truth-functional analysis of the boolean connectives. It is shown that on such an analysis the modality ‘determinately’ is quite clearly not an epistemic modality, avoiding a potential objection raised by Williamson against such ‘radically’ supervaluational treatments of vagueness, and that determinate truth is the semantic value preserved in classically valid arguments. The analysis is contrasted with the epistemicist proposal of Breckenridge and Magidor which implies that ‘\’ has a determinate but unknowable truth value. (shrink)

Hartry Field has recently examined the question whether our logical and mathematical concepts are referentially indeterminate. In his view, (1) certain logical notions, such as second-order quantification, are indeterminate, but (2) important mathematical notions, such as the notion of finiteness, are not (they are determinate). In this paper, I assess Field's analysis, and argue that claims (1) and (2) turn out to be inconsistent. After all, given that the notion of finiteness can only be adequately characterized in pure secondorder logic, (...) if Field is right in claiming that second-order quantification is indeterminate (see (1)), it follows that finiteness is also indeterminate (contrary to (2)). After arguing that Field is committed to these claims, I provide a diagnosis of why this inconsistency emerged, and I suggest an alternative, consistent picture of the relationship between logical and mathematical indeterminacy.

Teleological theories of content are thought to suffer from two related difficulties. According to the problem of indeterminacy, biological function is indeterminate in the sense that, in the case of two competing interpretations of the function of an evolved mechanism, there is often no fact of the matter capable of determining which function is the correct one. Therefore, any attempts to construct content out of biological function entail the indeterminacy of content. According to the problem of transparency, statements (...) of biological function are transparent in that a statement of the form 'the function of evolved mechanism M is to represent Fs' can be substituted salva veritate by a statement of the form 'the function of evolved mechanism M is to represent Gs' provided that the statement 'F iff G' is counterfactual supporting. Therefore, any attempt to construct content out of biological function must fail to capture the intensionality of psychological ascriptions. This paper argues that the teleological account is undermined by neither of these problems. Failure to appreciate this point stems from a conflation of two types of proper function - organismic and algorithmic - possessed by an evolved mechanism. These functions underwrite attributions of content to distinct objects. The algorithmic proper function of a mechanism underwrites attributions of content to the mechanism itself, while the organismic proper function of a mechanism underwrites attribution of content to the organism that possesses the mechanism. However the problems of indeterminacy and transparency arise only if the attributions of content attach to the same object. (shrink)

The topic of this paper is whether there is metaphysical vagueness. It is shown that it is important to distinguish between the general phenomenon of indeterminacy and the more narrow phenomenon of vagueness (the phenomenon that paradigmatically rears its head in sorites reasoning). Relatedly, it is important to distinguish between metaphysical indeterminacy and metaphysical vagueness. One can wish to allow metaphysical indeterminacy but rule out metaphysical vagueness. As is discussed in the paper, central argument against metaphysical vagueness, (...) like those of Gareth Evans and Mark Sainsbury, would if successful rule out metaphysical indeterminacy. One way to argue specifically against the possibility of metaphysical vagueness might be thought to be to argue for a specific theory of the nature of vagueness according to which vagueness is a semantic phenomenon. But it is shown that there are complications also pertaining to arguments with that structure. Toward the end of the paper, I discuss Trenton Merricks’ well-known argument against a semantic view on vagueness and for a metaphysical view. (shrink)

ABSTRACT Many phenomena appear to be indeterminate, including material macro-object boundaries and certain open future claims. Here I provide an account of indeterminacy in metaphysical, rather than semantic or epistemic, terms. Previous accounts of metaphysical indeterminacy have typically taken this to involve its being indeterminate which of various determinate states of affairs obtain. On my alternative account, MI involves its being determinate that an indeterminate state of affairs obtains. I more specifically suggest that MI involves an object's (...) having a determinable property, but not having any unique determinate of that determinable. I motivate the needed extension of the traditional understanding of determinables, then argue that a determinable-based account of MI accommodates, in illuminating fashion, both ‘glutty’ and ‘gappy’ cases of MI, while satisfactorily treating concerns about MI stemming from Evans’ argument and the problem of the many.

My theme here will be vagueness. But first recall Quine’s arguments for the indeterminacy of translation and the inscrutability of reference. (I will presume these arguments to be familiar.) If Quine is right, then there are radically different acceptable assignments of semantic values to the expressions of any language: different assignments of semantic values that for all that is determined by whatever it is that determines semantic value are all acceptable, and all equally good. Quine even (...) argued that the indeterminacy is so radical that some sentences are true under some acceptable assignments but false under others.1 Still, Quine does not allow intermediate truth-values or truthvalue gaps. (As I will put it, avoiding the disjunctive formulation: does not allow that there are sentences which are neuter.) Quine holds on to classical logic and bivalence and requires each acceptable assignment to be classical and bivalent.2. (shrink)
