Few if any distinctions are more easily recognisable and assented to than that between _objects_, that is, things which are some ways, and that which they are, that is, _ways for objects to be_ (‘ways of being’ for short). In this paper I present an argument designed to show that this distinction is indeterminate in the sense that the truth-conditions of predicational sentences leave open what should count as an object and a way of being. The bulk of the (...) argument is inspired by the celebrated permutation argument advanced by Quine, Wallace, Putnam and others. (shrink)

I argue that quine's thesis of the indeterminacy of radical translation is incorrect. the argument exploits the connections between quine's thesis and common sense notions regarding belief. a simple model of belief, taking beliefs to be sets of brain states, is used to give a rigorous restatement of quine's thesis. it is then argued that our need to project the actions of other people from their professions of belief would make the situation quine describes unstable, since persons in (...) that situation would make less accurate predictions of actions than would persons not so situated.

W.V.O. Quine's doctrines of the indeterminacy of translation and the inscrutability of reference are among the most famous and influential theses in philosophy in the past fifty years. Although by no means universally accepted, the arguments for them have been widely regarded as powerful challenges to our most fundamental beliefs about meaning and reference — including the belief that many of our words have meaning and reference in the sense in which we ordinarily understand those notions, as well (...) as beliefs about the particular things meant and referred to in specific cases, such as my belief that in the past my son Brian often referred with affection to his pet rabbit Bigwig. If Quine's doctrines, and the arguments for them, are correct, then beliefs such as these cannot be accepted as true.One might expect that with consequences like these Quine's theses would widely be regarded as obviously incorrect.

A central question for philosophical psychology is which mental faculties form natural kinds. There is hot debate over the kind status of faculties as diverse as consciousness, seeing, concepts, emotions, constancy and the senses. In this paper, I take emotions and concepts as my main focus, and argue that questions over the kind status of these faculties are complicated by the undeservedly overlooked fact that natural kinds are indeterminate in certain ways. I will show that indeterminacy issues have led (...) to an impasse in the debates over emotions and concepts. I first consider and reject one way of resolving this impasse. I then suggest a different method, which places more emphasis on a close analysis of predictive and explanatory practices in psychology. I argue that when we apply this method, a new position emerges: that it is indeterminate whether concepts or emotions are natural kinds. They are neither determinately natural kinds, nor determinately not natural kinds. Along the way, we will see that natural kinds have been put to two completely different theoretical uses, which are often been blurred together, and that they are ill-suited to fulfil one of them.

In this contribution I address the type of emergency that threatens a state’s monopoly of violence, meaning that the state’s competence to provide citizens with elementary security is challenged. The question is, whether actions taken by the state to ward off these threats (should) fall within the ambit of the criminal law. A central problem is the indeterminacy that is inherent in the state of emergency, implicating that adequate measures as well as constitutional constraints to be imposed on such (...) measures cannot easily be determined in advance. This indeterminacy raises two interrelated issues. Firstly, the issue of whether it makes sense to speak of criminal jurisdiction when the existing jurisdiction is challenged as such. To what extent does the indeterminacy call for inherently unlimited powers of the state, implying there can be no such thing as criminal jurisdiction during a state of emergency? Second—if criminal jurisdiction is not in contradiction with the state of emergency—the issue of what criminal liability could mean in such a state needs to be confronted. To what extent does the indeterminacy inherent in the state of emergency jeopardise criminal liability because such indeterminacy engenders severe legal uncertainty regarding the standards against which the relevant actions are to be judged? Both issues will be discussed from the perspective of constitutional democracy, assuming that what is at stake in times of emergency is both the competence to sustain the monopoly of violence and the possibility to constrain the powers of the state.

In this paper it is argued that the concept of translation failure involved in Kuhn's thesis of incommensurability is distinct from that of translational indeterminacy in Quine's sense. At most, Kuhnian incommensurability constitutes a weak form of indeterminacy, quite distinct from Quine's. There remains, however, a convergence between the two views of translation, namely, that there is no single adequate translation between languages.

It is commonly believed that Quine's principal argument for the Indeterminacy of Translation requires an untenably strong account of the underdetermination of theories by evidence, namely that that two theories may be compatible with all possible evidence for them and yet incompatible with each other. In this article, I argue that Quine's conclusion that translation is indeterminate can be based upon the weaker, uncontroversial conception of theoretical underdetermination, in conjunction with a weak reading of the ‘Gavagai’ argument which establishes (...) the underdetermination of the sense and reference of subsentential terms. If underdetermination is considered to be a widespread phenomenon in science, or in inductive reasoning more generally, then the Indeterminacy of Translation will be widespread too. Finally, I briefly consider two issues concerning the scope of this conclusion about the Indeterminacy of Translation: first, whether the argument presupposes behaviourism; and second, whether indeterminacy is restricted to the case of radical translation. I argue that the answer to both these questions is negative, and thus that the thesis of semantic indeterminacy remains relevant to those who disagree with Quine about some issues concerning the nature of mind and language.

I explain in what sense the structure of space and time is probably vague or indefinite, a notion I define. This leads to the mathematical representation of location in space and time by a vague interval. From this, a principle of complementary inaccuracy between spatial location and velocity is derived, and its relation to the Uncertainty Principle discussed. In addition, even if the laws of nature are deterministic, the behaviour of systems will be random to some degree. These and (...) other considerations draw classical physics closer to Quantum Mechanics. An arrow of entropy is also derived, given an arrow of time. Lastly, chaos is given an additional, objective meaning. (shrink)

Though the art of compromise, i.e. of settling differences by mutual concessions, is part of communal living on any level, we often think that there is something wrong in compromise, especially in cases where moral convictions are involved. A first reason for distrusting compromises on moral matters refers to the idea of integrity, understood in the basic sense of 'standing for something', especially standing for the values and causes that to some extent confer identity. The second reason points out (...) the objective nature of moral values, which seems to make them immune from negotiation and barter. If one sincerely holds some moral conviction to be true, than compromising on that belief must be a sign of serious confusion.In order to reach a better understanding of these two reasons, I analyse what is involved in personal integrity and how this relates to moral integrity. I argue that the search for moral integrity naturally brings us to the question of how one could accept moral compromises and still uphold the idea that moral values and principles have an objective authority over us. To address this question I will present a version of moral pluralism which tries to capture the enormous complexity of what should matter to us as moral persons, and which explains why value-rankings are often deeply indeterminate. The general position I defend in this paper is that compromises involving moral values and norms may be morally required and, therefore, be laudable. To sustain this position I will arrive at a view of ethical objectivity that allows the possibility to negotiate about the truth of moral beliefs. (shrink)

One might take the significance of Davidson’s indeterminacy thesis to be that the question as to which language we can take another to be speaking can only be settled relative to our choice of an acceptable theory for interpreting the speaker. This, in turn, could be taken to show that none of us is ever speaking a determinate language. I argue that this result is self-defeating and cannot avoid collapse into a troubling skepticism about meaning. I then offer a (...) way of trying to make sense of the idea that some utterances do belong to determinate languages even though there is no determinate language one can take another to be speaking. This, however, results in an uninviting picture of communication in which no speaker is really in a position to say what another’s words mean. (shrink)

In this essay I present a statement of Quine's indeterminacy thesis in its general form. It is shown that the thesis is not about difficulties peculiar to so-called "radical translation." It is a general thesis about meaning and reference with important consequences for any theory of our theories and beliefs. It is claimed that the thesis is inconsistent with Quine's realism, his doctrine of the relativity of reference, and that the argument for the thesis has the consequence that the (...) concept of stimulus meaning is empty. The sense in which linguistic science, as a branch of behavioral science, is "part of physics" is discussed. An alternative to Quine's view of the nature and content of linguistic science is proposed. It is shown to be consistent with Quine's assumptions concerning the legitimate scope of behavioral science and not to involve the notions of analyticity, synonymy and "prevalent attitudes toward meaning, idea and proposition" ([9], p. 304) rejected by Quine.

What does it mean to be a rational language user? What is it to obey linguistic rules? What is the proper account of linguistic competence? 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 guides us in the semantic evaluation process; and as for obeying rules, 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 exemplifies what it is like to follow a linguistic rule. My thesis explores a cluster of closely interrelated issues arising from these questions. 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 agreeing with Allan Gibbard that the theory of meaning really belongs to meta-ethical reflection. Chapter 1 introduces some of the main research questions that I try to address in the rest of the thesis. In chapter 2 I state a number of theses which I take to be the defining 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 abandon either the learnability or the compositionality constraint. The escape route I adopt, going radically minimalist about content, is incompatible with another key semanticist thesis, namely, that grasp of meaning is grasp of truth-conditions. In chapter 3, I consider the account of atomic meanings given by both the semanticist and the pragmaticist and I conclude that on neither account does interpretation come out as a process of rational choice between candidate bearers of content. Again, I suggest the lesson from indeterminacy is that we ought to embrace an ineradicably minimal conception of content. In chapter 4 I turn my attention to the meaning of the logical constants and I argue that indeterminacy worries extend to the very heart of the compositional machinery. Chapter 5 examines the view that logic is the science of reasoning. Unsurprisingly, I conclude that a defence of this claim requires endorsing content-minimalism. In chapter 6 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.

This paper deals with the problem of the origin of sense and meaning. For Husserl, the determination of the ideal identity of something new can only take place retroactively in the totality of the preceding series by stepping back towards the original foundation of sense. In this regard, J. Derrida questions the ideality of the same as presence and the possibility of retrieving any arché of sense in his writings Speech and Phenomena and Edmund Husserl’s Origin of (...) Geometry. Phenomenology is not oblivious to these difficulties, as results from a closer reading of the correlation between idealities and sensory experience: It will show that there are at least four interrelated gaps in the Husserlian phenomenology which testify the difficulty in grasping a retraceable arché of sense. First, the gap between the ideality of sense and its representation. Second, the gap between sensory and categorial intuitions, whereby both exceed one another. Third, the gap between the ideality of sense and the sense which exceeds our expectations. Fourth, the gap between the experience of the new that overcomes us and its apprehension by consciousness. Hence, there is a fundamental gap between the conceptual idealities and the essential indeterminacy of our phenomenological sensory experience, which is correlative to an excess of one in respect to the other. In this sense, Derrida’s concepts of « différance » and “invention” allow us to conceive of this self-givenness of sense as the expression of its constant self-renewal. This expression takes the form of a trace, which, neither present nor absent, suspends meaning and full presence, leaving the narrative “open” for the reinvention of sense. (shrink)

Markus Werning attempts to refute Quine’s thesis that meaning is indeterminate. To this purpose he employs Hodges’ theorem about extensions of cofinal meaning functions. But the theorem does neither suffice to solve Quine’s problem nor the problem Werning mistakenly identifies with Quine’s. Nevertheless it makes sense to employ the methods used in Werning’s paper with regard to Quine’s thesis, only that they tell in favour of the thesis instead of against it.

This is a meditation on love and suffering, pleasure and pain. Despite common sense, public discourse and scholarship narrating these states as diametrically opposed, the lived experience of queer romantic love cannot be disarticulated from the social realities of loss and pain. Suturing love and suffering is the metaphysic of indeterminacy, with the unexpected and uncertain marking romantic encounters and ambitions with precarity and impermanence. Drawing from vignettes gained through an ethnography on queer erotics in Sri Lanka in (...) 2016, I explore how queer love manifests and perishes in the most inexplicable fashion, against the backdrop of structural violence and the vagaries of intersubjective relationalities. A sensitivity to indeterminacy enables an excavation of the elsewheres that inhere to and are conjured by queer romantic love, from the entanglements that live outside of the binaries of heterosexual-homosexual to the utopic futural imaginaries that are made possible at this site. Meanwhile, the suffering engendered by indeterminacy gestures to the precarities of elsewhere, and the transient nature of queer futurity. I engage scholarship on social suffering and romantic love to demonstrate how both corpora of literature are united at the site of the Sri Lankan queer figure, and how centring indeterminacy troubles epistemic projects that seek to know love and the lover with certainty.

One of the goals of computerized tutoring systems is to optimize the learning of facts. Over a hundred years of declarative memory research have identified two robust effects that can improve such systems: the spacing and the testing effect. By making optimal use of both and adjusting the system to the individual learner using cognitive models based on declarative memory theories, such systems consistently outperform traditional methods. This adjustment process is driven by a continuously updated estimate of the rate of (...) forgetting for each item and learner on the basis of the learner's accuracy and response time. In this study, we investigated to what extent these estimates of individual rates of forgetting are stable over time and across different materials. We demonstrate that they are stable over time but not across materials. Even though most theories of human declarative memory assume a single underlying rate of forgetting, we show that, in practice, it makes sense to assume different materials are forgotten at different rates. If a computerized, adaptive fact-learning system allowed different rates of forgetting for different materials, it could adapt to individual learners more readily. (shrink)

This article analyses research that has explored the potential of a focus on indeterminate bodies for decision making, policy and politics. Drawing on different ways of conceptualising indeterminacy in scientific and policy domains it describes the Loweswater Care Project, a participatory ‘knowledge collective’ that attempted to avoid converting the complexities of vital cyanobacterial bodies into a purely social or managerial set of questions around water quality. Through a commitment to opening out the nature of ‘things’, participants in this collective (...) honed new questions and avenues of inquiry around cyanobacteria and its relations. The Loweswater Care Project was a kind of ‘open’ in Haraway’s sense, where questions and demands are put to bodies, and to the apparatus that allows us to sense them, in ways that do not shy away from the probabilistic character of entities and their relations. The implications of generating indeterminacies in this setting are explored for environmental decision making, policy and politics. (shrink)

The current literature on indeterminacy centers around two projects. One concerns the logic of indeterminacy; the other concerns its nature or source. The aim of this paper is to introduce, motivate and go some way toward addressing a new, third project: that of providing what I call a minimal characterization of indeterminacy. An MC, to a first approximation, is a relatively pre-theoretical characterization of indeterminacy that is neutral between the various substantive theories of the nature and (...) logic of indeterminacy. An MC thus captures a generic sense of indeterminacy that, at least in principle, is recognized by all parties to the debate over the phenomenon’s underlying nature and logic. I begin by introducing the concept of an MC and outlining some of the main theoretical virtues of providing an MC. I then establish some desiderata on a suitable MC, and use these desiderata to rule out various initially attractive proposals. In the final part of the paper I sketch the beginnings of my own MC and defend it against objections. (shrink)

The Claims of Common Sense investigates the importance of ideas developed by Cambridge philosophers between the World Wars for the social sciences concerning common sense, vague concepts and ordinary language. John Coates examines the thought of Moore, Ramsey, Wittgenstein and Keynes, and traces their common drift away from early beliefs about the need for precise concepts and a canonical notation in analysis. He argues that Keynes borrowed from Wittgenstein and Ramsey their reappraisal of vague concepts, and developed the (...) novel argument that when analysing something as complex as social reality, theory might be simplified by using concepts which lack sharp boundaries. Coates then contrasts this conclusion with the view shared by two contemporary philosophical paradigms - formal semantics and Continental post-structuralism - that the vagueness of ordinary language inevitably leads to interpretive indeterminacy. Developing a link between Cambridge philosophy and work on complexity, vague predicates and fuzzy logic, he argues that Wittgenstein's and Keynes's ideas on the economy of ordinary language present a mediating route for the social sciences between these philosophical paradigms.

Modern social theory, by and large, has aimed at reducing the complexity of action situations to a set of manageable abstractions. But these abstractions, whether functionalist or linguistic, fail to grasp the indeterminacy of action situations.Action proceeds by discovery and combination. The logic of action is serendipitous and combinative. From these characteristics, a number of consequences flow: The whole field of our intentions is engaged in each action situation, and cannot really be understood apart from the situation itself. In (...) action situations we remain aware of the problems of categorization, including the dangers of infinite regress and the difficulties of specifying borders and ranges of categories. In action situations, attention is in permanent danger of being overwhelmed. We must deal with many features of action situations outside of attention; in doing so, we must entertain simultaneously numerous possibilities of action. Emotional expression is a way of talking about the kinds of possibilities we entertain. Expression and action have a rebound effect on attention. "Effort" is required to find appropriate expressions and actions, and rebound effects play a role in such effort, making it either easier or more difficult.Recent theoretical trends have failed to capture these irreducible characteristics of action situations, and have slipped into a number of errors. Language is not rich in meanings or multivocal, except as put to use in action situations. The role of "convention" in action situations is problematic, and therefore one ought not to talk of "culture." Contrary to the assertions of certain theorists, actors do not follow strategies, except when they decide to do so. Actors do not "communicate," in the sense of exchanging information, except in specially arranged situations. More frequently, they intervene in the effortful management of attention of their interlocutors. Dialogue, that is, very commonly becomes a form of cooperative emotional effort.From these considerations, it follows that the proper method for gaining social knowledge is to examine the history of action and of emotional effort, and to report findings in the form of narrative.

Social ontologists commonly think that our ideas about social entities, and about other people also inhabiting the social realm, play an important role in making those entities into what they are. At the same time, we know that our ideas are often indeterminate in character, which presumably would mean that this indeterminacy should carry over to the social realm. And yet social indeterminacy is a neglected topic in social ontology. It is argued that this neglect can be traced (...) to how a particular approach that favors ahistorical reconstructions in making sense of social entities has come to dominate social ontology. If we think beyond the parameters set by this approach, however, we can see that recognizing indeterminacy as a pervasive phenomenon in the social realm might open up new interpretative possibilities in relation to different social categories. This argument is at least partly in line with recent calls for a move towards nonideal social ontology. (shrink)

The aim of this study was to assess attitudes of intensive care nurses to selected ethical issues related to end-of-life decisions in paediatric intensive care units. A self-administered questionnaire was distributed in 2005 to intensive care nurses at two different scientific occasions in Turkey. Of the 155 intensive care nurse participants, 98% were women. Fifty-three percent of these had intensive care experience of more than four years. Most of the nurses failed to agree about withholding (65%) or withdrawing (60%) futile (...) treatment. In addition, 68% agreed that intravenous nutrition must continue at all costs. In futile treatment cases, the nurses tended to leave the decision to parents or act maternalistically. The results showed that intensive care nurses could ignore essential ethical duties in end-of-life care. We suggest that it is necessary to educate Turkish intensive care nurses about ethical issues at the end of life. (shrink)

In concept, an image has both verticality and horizontal dimensions. Saturated images within this space have a horizon and can exceed that horizon. Within that horizon where the image dwells something chances itself upon the observer and the observed. Into that public space between self and other, students bring an instrumental approach to how they plan to deploy their new fund of knowledge, only to discover that the setting itself has become an event where surprise and upheaval disrupt their illusion (...) of self-continuity and the façade of familiarity. Phenomenologically, upheaval shows itself when givenness both precedes and participates in the giving of phenomena such as medical students’ “before and after” images of psychoanalysis. They discover and reconfigure their erstwhile absolute positions and values into reconfigurations of self and prior commitments. The turning point from their instrumental use of knowledge to reconfigurations of how they situate themselves in the world decisively comes when teaching and learning become an event in se that disturbs their sense of order.Following Husserl, phenomenological psychological observation has required us to go from the events of history to a sense of history. Would, however, that we could stay at the level of events much longer to see images explode and exceed their horizons from the illusion of order, and patterned repetition disrupted by surprise, upheaval and indeterminacy in the spirit of Alain Badiou!

For Jizang (549−623), a prominent philosophical exponent of Chinese Madhyamaka, all things are empty of determinate form or nature. Given anything X, no linguistic item can truly and conclusively be applied to X in the sense of positing a determinate form or nature therein. This philosophy of ontic indeterminacy is connected closely with his notion of the Way (dao), which seems to indicate a kind of ineffable principle of reality. However, Jizang also equates the Way with nonacquisition as (...) a conscious state of freedom from any attachment and definite understanding whatsoever. The issue then becomes pressing as to how we are to understand Jizang's notion of the Way. Does it indicate some metaphysical principle or reality? Is it actually a skilful expedient to lead one to the consummate state of complete spiritual freedom? How is this issue related to Jizang's conception of ontic indeterminacy? In this book chapter, I examine Jizang's key writings in an attempt to clarify his ontological position. (shrink)

The aim of this paper is to define a partial Propositional Type Theory. Our system is partial in a double sense: the hierarchy of (propositional) types contains partial functions and some expressions of the language, including formulas, may be undefined. The specific interpretation we give to the undefined value is that of Kleene’s strong logic of indeterminacy. We present a semantics for the new system and prove that every element of any domain of the hierarchy has a name (...) in the object language. Finally, we provide a proof system and a (constructive) proof of completeness. (shrink)

The paper seeks to show that Quine’s theses concerning the underdetermination of scientific theories by experience and the indeterminacy of reference cannot be reconciled if some of Quine’s central assumptions are accepted. The argument is this. Quine holds that the thesis about reference is not just a special case of the other thesis. In order to make sense of this comment we must distinguish between factual and epistemic indeterminacy. Something is factual indeterminate if it is not determined (...) by the facts. Epistemic indeterminacy, on the other hand, is due to the lack of evidence. Quine’s claim about the relationship between the two theses is best understood as saying that reference is factually indeterminate, whereas the underdetermination of scientific theories is merely epistemic. But the latter cannot be sustained in light of Quine’s verificationism, holism and naturalism. (shrink)

The fields of machine learning (ML) and cognitive science have developed complementary approaches to computationally modeling human behavior. ML's primary concern is maximizing prediction accuracy; cognitive science's primary concern is explaining the underlying mechanisms. Cross-talk between these disciplines is limited, likely because the tasks and goals usually differ. The domain of e-learning and knowledge acquisition constitutes a fruitful intersection for the two fields’ methodologies to be integrated because accurately tracking learning and forgetting over time and predicting future performance based on (...) learning histories are central to developing effective, personalized learning tools. Here, we show how a state-of-the-art ML model can be enhanced by incorporating insights from a cognitive model of human memory. This was done by exploiting the predictive performance equation's (PPE) narrow but highly specialized domain knowledge with regard to the temporal dynamics of learning and forgetting. Specifically, the PPE was used to engineer timing-related input features for a gradient-boosted decision trees (GBDT) model. The resulting PPE-enhanced GBDT outperformed the default GBDT, especially under conditions in which limited data were available for training. Results suggest that integrating cognitive and ML models could be particularly productive if the available data are too high-dimensional to be explained by a cognitive model but not sufficiently large to effectively train a modern ML algorithm. Here, the cognitive model's insights pertaining to only one aspect of the data were enough to jump-start the ML model's ability to make predictions—a finding that holds promise for future explorations.

Far from being unwelcome or impossible in a mathematical setting, indeterminacy in various forms can be seen as playing an important role in driving mathematical research forward by providing “sources of newness” in the sense of Hutter and Farías :434–449, 2017). I argue here that mathematical coincidences, phenomena recently under discussion in the philosophy of mathematics, are usefully seen as inducers of indeterminacy and as put to work in guiding mathematical research. I suggest that to call a (...) pair of mathematical facts a coincidence is roughly to suggest that the investigation of connections between these facts isn’t worthwhile. To say of this pair, “That’s no coincidence!” is to suggest just the opposite. I further argue that this perspective on mathematical coincidence, which pays special attention to what mathematical coincidences do, may provide us with a better view of what mathematical coincidences are than extant accounts. I close by reflecting on how understanding mathematical coincidences as generating indeterminacy accords with a conception of mathematical research as ultimately aiming to reduce indeterminacy and complexity to triviality as proposed in Rota Indiscrete thoughts, Birkhäuser, 1997).

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)

David Cooper has argued that any acceptable theory of metaphor should account for ‘indeterminacy’: the sense that many metaphors admit of multiple acceptable interpretations, none of which can be uniquely demonstrated to be correct. He further argues that the ‘speaker's meaning’ model of metaphorical content cannot meet this constraint and, thus, should be rejected. In this paper I argue that Cooper's characterization of the proposed constraint is imprecise as stated and give my own characterization of the problem. There (...) is a general tension between the authority granted to first-person ascriptions of intentions and facts concerning the phenomenology of metaphor production, given that it seems to misrepresent the latter to ascribe to the speaker special access to a cognitive content, which their metaphorical utterance then expresses. I argue that one way of resolving this tension is by following Crispin Wright in viewing facts about intention as essentially response dependent. (shrink)

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)

There is a tension between the “growing block” account of time (closed past, open future) and the possibility of backwards time travel. If Tim the time traveler can someday travel backwards through time, then he has (in a certain sense) already been. He might discover this fact before (in another sense) he goes. Hence a dilemma: it seems that either Tim’s future is determined in an odd way or cases of (temporary) ontic indeterminate identity are possible. Either Tim (...) cannot avoid heading for the past or he is only indeterminately that guy who appeared in the past with many of Tim’s memories. Determinacy in the past implies a degree of determinism in the future; indeterminism about the future seeps back to the past. (shrink)

Roth (1987) effectively distinguishes Quinean indeterminacy of translation from the more general underdetermination of theories by showing how indeterminacy follows directly from holism and the role of a shared environment in language learning. However, Roth is mistaken in three further consequences he draws from his interpretation of indeterminacy. Contra Roth, natural science and social science are not differentiated as offering theories about the shared environment and theories about meanings respectively; the role of the environment in language learning (...) does not justify an empiricist sense of objective evidence; and his advocacy of methodological pluralism does not appropriately sustain the project of social scientific methodology in response to holism and indeterminacy.

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)

Although appeals to human dignity became quite popular after the end of War World II in various moral and legal settings, the term retained an air of semantic indeterminacy, and scholars are of opposing minds concerning its usefulness and significance. In this essay I intend to offer a sketch of a “deflationary” account of human dignity – viewed as one moral value among many others – according to which it is conceived as the minimal respect we prima facie owe (...) to our own personality, as well as to the personality of everyone else without any restriction or exception. This account is accompanied by a justification, which does not presuppose the endorsement of a particular moral theory, and envisages dignity as a bulwark to counter the morally abhorrent consequences of many categorical and normatively tainted dichotomies western societies have created.

Common-sense morality includes various agent-centred constraints, including ones against killing unnecessarily and breaking a promise. However, it's not always clear whether, had an agent ϕ-ed, she would have violated a constraint. And sometimes the reason for this is not that we lack knowledge of the relevant facts, but that there is no fact about whether her ϕ-ing would have constituted a constraint-violation. What, then, is a constraint-accepting theory to say about whether it would have been permissible for her to (...) have ϕ-ed? In this paper, I canvass various possible approaches to answering this question and I argue that teleology offers the most plausible approach—teleology being the view that every act has its deontic status in virtue of how its outcome ranks, relative to those of its alternatives. So although, until recently, it had been thought that only deontological theories can accommodate constraints, it turns out that teleological theories not only can accommodate constraints, but can do so more plausibly than deontological theories can.

Lodged in an impasse between questions of environmental justice and modes of capitalisation in the green economy, indeterminacy is a vulnerable and porous relation. Pollution activates a potentiality in the organism to be otherwise, to generate certain kinds of tumours, mini-deaths or mutations. Toxicity has an intermediary status that launches a mobility of effects that is often fragmented through sense organs, affirming forms of non-identity in biopolitical relations. Organisms are receptive to such bodily reconfigurations precisely because they are (...) open to the material communication of the world. In contrast to the “hidden labour” of indeterminacy in capitalist modes of capture, this article crafts an analytics of indeterminacy as an interjection in the politics of environments. Through dispersants in the Gulf of Mexico and military bees, two economies of indeterminacy are discussed. Drawing on Georges Bataille’s notion of political economy, I argue that what is required is an economy of radical inequivalence; an excessive engagement with the possibilities of indetermining forces to make fleeting marks.
