Reliable misrepresentation is getting things wrong in the same way all the time. In Mendelovici 2013, I argue that tracking theories of mental representation cannot allow for certain kinds of reliable misrepresentation, and that this is a problem for those views. Artiga 2013 defends teleosemantics from this argument. He agrees with Mendelovici 2013 that teleosemantics cannot account for clean cases of reliable misrepresentation, but argues that this is not a problem for the views. This paper clarifies and improves (...) the argument in Mendelovici 2013 and response to Artiga's arguments. Tracking theories, teleosemantics included, really do need to allow for clean cases of reliable misrepresentation. (shrink)

My task here is to articulate my own novel hybrid theory of (claim-)rights, namely, the Tracking Theory of rights. While new, it has historical antecedents. There is nothing (entirely) new under the sun. Its most vivid antecedents come from the fields of epistemology, in particular Robert Nozick's work, and legal philosophy, in particular Gopal Sreenivasan's work. I am happy to stand on the shoulders of giants. Here I want to freshly articulate the theory from the ground up. So the (...) challenge will be to keep the articulation of the Tracking Theory front and centre, but, naturally, indebtedness to Nozick and Sreenivasan will be woven in at multiple junctures. My Tracking Theory will neither stand nor fall with Nozick's. The relation is more subtle. The strategy is to trade on the indubitable subtlety of Nozick's epistemology to capture the structure of a central normative concept. (shrink)

Since Kripke's attack on Nozick's Tracking Theory of knowledge, there has been strong suspicion that tracking theories are false. We think that neither Kripke's arguments and examples nor other recent attacks in the literature show that the tracking theories are false. We cannot address all of these concerns here, but we will show why some of the most discussed examples from Kripke do not demonstrate that the tracking theories are false.

The dual-track theory of moral reasoning has received considerable attention due to the neuroimaging work of Greene et al. Greene et al. claimed that certain kinds of moral dilemmas activated brain regions specific to emotional responses, while others activated areas specific to cognition. This appears to indicate a dissociation between different types of moral reasoning. I re-evaluate these claims of specificity in light of subsequent empirical work. I argue that none of the cortical areas identified by Greene et al. are (...) functionally specific: each is active in a wide variety of both cognitive and emotional tasks. I further argue that distinct activation across conditions is not strong evidence for dissociation. This undermines support for the dual-track hypothesis. I further argue that moral decision-making appears to activate a common network that underlies self-projection: the ability to imagine oneself from a variety of viewpoints in a variety of situations. I argue that the utilization of self-projection indicates a continuity between moral decision-making and other kinds of complex social deliberation. This may have normative consequences, but teasing them out will require careful attention to both empirical and philosophical concerns. (shrink)

This paper compares tracking and phenomenal intentionality theories of intentionality with respect to the issue of naturalism. Tracking theories explicitly aim to naturalize intentionality, while phenomenal intentionality theories generally do not. It might seem that considerations of naturalism count in favor of tracking theories. We survey key considerations relevant to this claim, including some motivations for and objections to the two kinds of theories. We conclude by suggesting that naturalistic considerations may in (...) fact support phenomenal intentionality theories over tracking theories. (shrink)

Street’s (Philos Stud 127(1):109–166, 2006) Darwinian Dilemma purports to show that evolutionary considerations are in tension with realist theories of value, which include moral realism. According to this argument, moral realism can only be defended by assuming an implausible tracking relation between moral attitudes and moral facts. In this essay, I argue that this tracking relation is not as implausible as most people have assumed by showing that the three main objections against it are flawed. Since this (...) is a key premise in the reasoning, I conclude that the Darwinian Dilemma against moral realism can be resisted. (shrink)

Much of contemporary epistemology proceeds on the assumption that tracking theories of knowledge, such as those of Dretske and Nozick, are dead. The word on the street is that Kripke and others killed these theories with their counterexamples, and that epistemology must move in a new direction as a result. In this paper we defend the tracking theories against purportedly deadly objections. We detect life in the tracking theories, despite what we perceive to (...) be a premature burial. (shrink)

As teorias epistemológicas do rastreamento sustentam que o conhecimento é uma relação real entre o agente cognitivo e seu ambiente. Os estados cognitivos de um agente epistêmico fazem o rastreamento da verdade das proposições que são objeto de conhecimento ao embasarem a crença em indicadores confiáveis da verdade (evidência, razões, ou métodos de formação de crença). A novidade nessa abordagem é que se dá pouca ênfase no tipo de justificação epistêmica voltada ao fornecimento de procedimentos de decisão doxástica ou regras (...) de responsabilidade epistêmica. Este artigo oferece um pouco da história das teorias de rastreamento e, então, defende-as contra muitas objeções que se pretendem (equivocadamente) refutadoras dessas teorias. PALAVRAS – CHAVE – Teorias de rastreamento. Nozick. Dretske. Conhecimento. ABSTRACT Tracking theories of knowledge maintain that knowledge is a real relation between cognitive agent and environment. Cognitive states of a knower track the truth of known propositions by basing belief on reliable indicators of truth (evidence, reasons, or belief forming methods). The novelty of this approach is that it places little emphasis on epistemic justification of a kind that aims at guiding epistemic agents by giving doxastic decision procedures or rules of epistemic responsibility. This paper gives some of the history of tracking theories, and then defends them against many of the objections most often judged (mistakenly) to refute tracking theories.

It is a live possibility that certain of our experiences reliably misrepresent the world around us. I argue that tracking theories of mental representation have difficulty allowing for this possibility, and that this is a major consideration against them.

In a recent paper, Tristan Haze offers two examples that, he claims, are counterexamples to Nozick's Theory of Knowledge. Haze claims his examples work against Nozick's theory understood as relativized to belief forming methods M. We believe that they fail to be counterexamples to Nozick's theory. Since he aims the examples at tracking theories generally, we will also explain why they are not counterexamples to Dretske's Conclusive Reasons Theory of Knowledge.

Rachael Briggs and Daniel Nolan attempt to improve on Nozick’s tracking theory of knowledge by providing a modified, dispositional tracking theory. The dispositional theory, however, faces more problems than those previously noted by John Turri. First, it is not simply that satisfaction of the theory’s conditions is unnecessary for knowledge – it is insufficient as well. Second, in one important respect, the dispositional theory is a step backwards relative to the original tracking theory: the original but not (...) the dispositional theory can avoid Gettier-style counterexamples. Future attempts to improve the tracking theory would be wise to bear these problems in mind. (shrink)

I present two counterexamples to the recently back-in-favour truth-tracking account of knowledge: one involving a true belief resting on a counterfactually robust delusion, one involving a true belief acquired alongside a bunch of false beliefs. These counterexamples carry over to a recent modification of the theory due to Briggs and Nolan (2012), and seem invulnerable to a recent defence of the theory against known counterexamples, by Adams and Clarke (2005).

To explain agent-identification behaviours, universalist theories in the biological and cognitive sciences have posited mental mechanisms thought to be universal to all humans, such as agent detection and face recognition mechanisms. These universalist theories have paid little attention to how particular sociocultural or historical contexts interact with the psychobiological processes of agent-identification. In contrast to universalist theories, contextualist theories appeal to particular historical and sociocultural contexts for explaining agent-identification. Contextualist theories tend to adopt idiographic methods (...) aimed at recording the heterogeneity of human behaviours across history, space, and cultures. Defenders of the universalist approach tend to criticise idiographic methods because such methods can lead to relativism or may lack generality. To overcome explanatory limitations of proposals that adopt either universalist or contextualist approaches in isolation, I propose a philosophical model that integrates contributions from both traditions: the psycho-historical theory of agent-identification. This theory investigates how the tracking processes that humans use for identifying agents interact with the unique socio-historical contexts that support agent-identification practices. In integrating hypotheses about the history of agents with psychological and epistemological principles regarding agent-identification, the theory can generate novel hypotheses regarding the distinction between recognition-based, heuristic-based, and explanation-based agent-identification.

Typical theory of mind tasks assess children’s ability to attribute a false belief in order to predict or explain an action. According to these standard tasks, young children do not represent the independent (mistaken) beliefs of others until the fourth year—yet long before this, children are able to track speakers’ intentions in order to learn new words. Might communication be a privileged domain for theory of mind? In the present study we explored pre‐schoolers’ ability to track a false belief in (...) order to acquire a novel word. A puppet labeled a novel object in a false belief condition (contents of a box had been switched without her knowledge), and a true belief condition (contents switched in her presence). Children were significantly better at tracking the puppet’s false belief in the word‐learning task than in a standard false belief test. Possible reasons for this advantage are discussed, and the suggestion made that representation of mental states may emerge precociously in the service of communication. (shrink)

To improve the accuracy and timeliness of the trajectory tracking control of the driverless racing car during the race, this paper proposes a track tracking control method that integrates the rear wheel differential drive and the front wheel active steering based on optimal control theory and fuzzy logic method. The model of the lateral track tracking error of the racing car is established. The model is linearized and discretized, and the quadratic optimal steering control problem is constructed. (...) Taking advantage of the differential drive of dual-motor-driven racing car, the dual motors differential drive fuzzy controller is designed and integrated driving with active steering control. Simulation analysis and actual car verification show that this integrated control method can ensure that the car tracks different race tracks well and improve the track tracking control accuracy by nearly 30%.

How do humans manage to keep track of a gradually changing object or person as the same persisting individual despite the fact that the extraction of information about this individual must often rely on heterogeneous information sources and heterogeneous tracking methods? The article introduces the Empirical Tracking of Individuals theory to address this problem. This theory proposes an analysis of the concept of integrated tracking, which refers to the capacity to acquire, store, and update information about the (...) identity and location of individuals in our environment. It hypothesizes that certain functions of attention are a key to explaining how the cognitive flexibility of the human mind overcomes the heterogeneity of sources and methods in integrated tracking. At least two premises lend support to this hypothesis. First, heterogeneity of tracking sources is overcome by the combination of information from multiple perceptual modalities and a phenomenon of multisensory 'transparency'. Second, heterogeneity of tracking sources and methods may also be overcome by inferences that combine information across domains to acquire reasons to believe propositions about the target's location and identity.

According to Nozick’s tracking theory of knowledge, an agent a knows that p just in case her belief that p is true and also satisfies the two tracking conditionals that had p been false, she would not have believed that p , and had p been true under slightly different circumstances, she would still have believed that p . In this paper I wish to highlight an interesting but generally ignored feature of this theory: namely that it is (...) reminiscent of a dispositional account of knowledge: it invites us to think of knowledge as a manifestation of a cognitive disposition to form true beliefs. Indeed, given a general account of dispositions in terms of subjunctive conditionals, the two tracking conditionals are satisfied just in case the belief in question results from some cognitive disposition to form true beliefs. Recently, such a conditional account of dispositions has, however, been criticised for its vulnerability to so-called ‘masked’, ‘mimicked’ and ‘finkish’ counterexamples. I show how the classical counterexamples to Nozick’s theory divide smoothly into four corresponding categories of counterexamples from epistemic masking, mimicking and finkishness. This provides strong evidence for the thesis that satisfaction of the two tracking conditionals is symptomatic of knowledge and that knowledge is instead constituted by a dispositional capability to form true beliefs. The attempt to capture such a cognitive, dispositional capability in terms of the tracking conditionals, although providing a good approximation in a wide variety of cases, still comes apart from the real thing whenever the epistemic layout is characterised by masking-, mimicking- and finkish mechanisms. In the last part of the paper I explore the prospect of improving the tracking theory in the light of these findings. (shrink)

Tracking theories see knowledge as a relation between a subject’s belief and the truth, where the former is responsive to the latter. This relationship involves causation in virtue of a sensitivity condition, which is constrained by an adherence condition. The result is what I call a stable causal relationship between a fact and a subject’s belief in that fact. I argue that when we apprehend the precise role of causation in the theory, previously obscured problems pour out. This (...) paper presents thirteen distinct and original counterexamples to Nozick’s tracking theory—many of which also constitute problems for more recent tracking theories. I begin by discussing how tracking relates to causation: Nozick invokes causation through conditions similar to those of Lewisian causal dependence. As a result, when causal dependence is not necessary for causation, Nozick fails to identify knowledge. I then address the inability of causation to capture epistemically important concepts, such as justification and truth. I conclude by discussing the underlying asymmetries between causation and knowledge that undermine any attempt to reduce knowledge to a purely metaphysical relation. (shrink)

In “Reliabilism Leveled” Jonathan Vogel (2000) provides a strong case against epistemic theories that stress the importance of tracking/sensitivity conditions. A tracking/sensitivity condition is to be understood as some version of the following counterfactual: (T) ~p oÆ ~Bp (T) says that s would not believe p, if p were false. Among other things, tracking is supposed to express the external relation that explains why some justified true beliefs are not knowledge. Champions of the condition include Robert (...) Nozick (1981) and, more recently, Keith DeRose (1995). To my knowledge, the earliest formulation of the counterfactual condition is found in Fred Dretske’s conclusive reasons condition (1971), which says, s would not have had the reason that she does for believing p, if p were false. Vogel contends that any such counterfactual condition on knowledge will render the theory of knowledge too strong. He believes that there is at least some possible reflective knowledge that cannot satisfy the counterfactual--viz., the possible knowledge that one does not believe falsely that p. The alleged impossibility of such reflective knowledge is taken by Vogel to be a decisive objection to the tracking theories advocated by Dretske, Nozick, DeRose1 and others. The criticism finds its roots in Vogel’s earlier work (1987), and recurs in papers by Ernest Sosa (2002, 1996). Sosa suggests that the externalist idea behind tracking is on target, but that Nozick’s counterfactual is a misbegotten regimentation of the idea. In its place Sosa offers his own counterfactual “safety” condition, which he feels properly captures the externalist idea. Sosa’s counterfactual is not the topic of this paper. I mention it only to point out that the criticism that constitutes the subject of my investigation is meant to do a lot of work. In Sosa’s 1 case the criticism is meant to motivate his own counterfactual analysis, and in Vogel’s case the criticism promises to be a silver bullet against a theory that has recently found renewed life in the work of Keith DeRose..

International relations theories have often been faulted for not advancing falsifiable forecasts. Given the complexities of geopolitics and the near impossibility of satisfying the “ceteris paribus” clause in scientific hypothesis testing, this criticism imposes an unfair standard. It is reasonable however to ask about the predictive track records of international relations theorists who enter high-stakes policy debates. Whether a neorealist of neo-institutionalist proves an adroit or maladroit forecaster sheds little light on the truth status of their preferred theory but (...) considerable light on: (a) how much credence to attach to their claims about the likely outcomes of pursuing various policy options in specific theaters of conflict; (b) how superior forecasters blend abstract covering laws with real-world knowledge to generate well-calibrated probability estimates.

In relevant logics, necessary truths need not imply each other. In justification logic, necessary truths need not all be justified by the same reason. There is an affinity to these two approaches that suggests their pairing will provide good logics for tracking reasons in a fine-grained way. In this paper, I will show how to extend relevant logics with some of the basic operators of justification logic in order to track justifications or reasons. I will define and study three (...) kinds of frames for these logics. For the first kind of frame, I show soundness and highlight a difficulty in proving completeness. This motivates two alternative kinds of frames, with respect to which completeness results are obtained. Axioms to strengthen the justification logic portions of these logics are considered. I close by developing an analogy between the dot operator of justification logic and theory fusion in relevant logics. (shrink)

Is it possible to gain knowledge about the real world based solely on experiences in virtual reality? According to one influential theory of knowledge, you cannot. Robert Nozick's truth-tracking theory requires that, in addition to a belief being true, it must also be sensitive to the truth. Yet beliefs formed in virtual reality are not sensitive: in the nearest possible world where P is false, you would have continued to believe that P. This is problematic because there is increasing (...) awareness from philosophers and technologists that virtual reality is an important way in which we can arrive at beliefs and knowledge about the world. Here I argue that a suitably modified version of Nozick's sensitivity condition is able to account for knowledge from virtual reality. (shrink)

Self-tracking practices include the use of personal data-gathering apps, wearable devices, and data analysis tools to record patterns from daily activities, as well as the organization, visualization, and analysis of this data. This paper draws on theories of digital labour and feminist political economy to build a framework of digital productive labour that highlights the exploitation of activities external to the formal labour relationship. Self-tracking practices are analysed through the lens of digital productive insofar as they fulfill (...) three roles: they generate the content necessary for sustaining digital networks and producing data that can be captured in commodity form; they aid in the reproduction of the social factory’s labour force; and they cultivate subjectivities amenable to consumption and production in contemporary capitalism. The paper examines the production and commodification of data, highlighting the algorithmic means by which self-trackers are separated from the financial value of their data. This is connected to feminist analyses of unpaid labour, with particular attention to self-tracking’s role as a contemporary form of reproductive labour that replenishes the labour force. Finally, the paper provides an analysis of the themes of self-knowledge, self-discovery, and gamification to understand how these frame self-trackers’ understanding of themselves as labourers, thus reproducing and deepening capitalist subjectivities. The paper concludes by considering self-tracking through the lens of the exploitation of life ‘outside’ the official labour relationship. (shrink)

Sherrilyn Roush defends a new theory of knowledge and evidence, based on the idea of "tracking" the truth, as the best approach to a wide range of questions about knowledge-related phenomena.

Tracking Truth provides a unification of the concepts of knowledge and evidence, and argues against traditional epistemological realist and anti-realist positions about scientific (...) class='Hi'>theories and for a piecemeal approach based on a criterion of evidence, a position Roush calls "real anti-realism." Epistemologists and philosophers of science will recognize this as a significant original contribution. (shrink)

For corporate memory and enterprise ontology systems to be maximally useful, they must be freed from certain barriers placed around them by traditional knowledge management paradigms. This means, above all, that they must mirror more faithfully those portions of reality which are salient to the workings of the enterprise, including the changes that occur with the passage of time. The purpose of this chapter is to demonstrate how theories based on philosophical realism can contribute to this objective. We discuss (...) how realism-based ontologies (capturing what is generic) combined with referent tracking (capturing what is specific) can play a key role in building the robust and useful corporate memories of the future.

In three experiments, subjects attempted to track multiple items as they moved independently and unpredictably about a display. Performance was not impaired when the items were briefly (but completely) occluded at various times during their motion, suggesting that occlusion is taken into account when computing enduring perceptual objecthood. Unimpaired performance required the presence of accretion and deletion cues along fixed contours at the occluding boundaries. Performance was impaired when items were present on the visual field at the same times and (...) to the same degrees as in the occlusion conditions, but disappeared and reappeared in ways which did not implicate the presence of occluding surfaces (e.g. by imploding and exploding into and out of existence, instead of accreting and deleting along a fixed contour). Unimpaired performance did not require visible occluders (i.e. Michotte’s tunnel effect) or globally consistent occluder positions. We discuss implications of these results for theories of objecthood in visual attention. (shrink)

This article employs Foucauldian and feminist analytics to advance a critical approach to wearable digital health- and activity-tracking devices. Following Foucault’s insight that the growth of individual capabilities coincides with the intensification of power relations, I argue that digital self-tracking devices (DSTDs) expand individuals’ capacity for self-knowledge and self-care at the same time that they facilitate unprecedented levels of biometric surveillance, extend the regulatory mechanisms of both public health and fashion/beauty authorities, and enable increasingly rigorous body projects devoted (...) to the attainment of normative femininity. These technologies of surveillance, normalization, and discipline thus function to augment, and facilitate the cooperation of, neoliberal-era biopower and post-feminist patriarchal power. My analysis of digital self-tracking devices’ instrumentality to biopower and patriarchy contributes to the emergent field of critical digital health studies and builds new connections between political, social, and feminist theories of embodiment; biopower studies; fat studies; and trans-disciplinary body studies.

This article argues that Habermas’s position on the relationship between religion and politics reaffirms his two-track political theory of the secular state and civic duty. His “hard-core” theory of secularism coupled with an ethics of citizenship seeks new ways of including religious citizens in modern pluralistic societies. The analysis of secularism both as a concept and as a guiding principle in Habermas’s work shows that most critics have misinterpreted his specific use of the term. The result of this is that (...) most secularist and accommodationist critics of Habermas’s ethics of citizenship disregard his two-track political theory and its co-originality principle that assumes the equal status of public and private autonomies of citizens. My aim is thus to shift critical attention to the central aspects of Habermas’s work on religion, specifically to the task of translating religious reasons into an all-accessible language. This task of translation faces several difficulties due to some points that are left unclear by Habermas, such as determining the line separating the informal and the formal spheres, and how to avert the risk of majoritarian hijacks of democracy that could altogether undermine the Habermasian framework.

Although several theories of online syntactic processing assume the parallel activation of multiple syntactic representations, evidence supporting simultaneous activation has been inconclusive. Here, the continuous and non‐ballistic properties of computer mouse movements are exploited, by recording their streaming x, y coordinates to procure evidence regarding parallel versus serial processing. Participants heard structurally ambiguous sentences while viewing scenes with properties either supporting or not supporting the difficult modifier interpretation. The curvatures of the elicited trajectories revealed both an effect of visual (...) context and graded competition between simultaneously active syntactic representations. The results are discussed in the context of 3 major groups of theories within the domain of sentence processing. (shrink)

ABSTRACT Drawing inspiration from Fred Dretske, L. S. Carrier, John A. Barker, and Robert Nozick, we develop a tracking analysis of knowing according to which a true belief constitutes knowledge if and only if it is based on reasons that are sensitive to the fact that makes it true, that is, reasons that wouldn’t obtain if the belief weren’t true. We show that our sensitivity analysis handles numerous Gettier-type cases and lottery problems, blocks pathways leading to skepticism, and validates (...) the epistemic closure thesis that correct inferences from known premises yield knowledge of the conclusions. We discuss the plausible views of Ted Warfield and Branden Fitelson regarding cases of knowledge acquired via inference from false premises, and we show how our sensitivity analysis can account for such cases. We present arguments designed to discredit putative counterexamples to sensitivity analyses recently proffered by Tristan Haze, John Williams and Neil Sinhababu, which involve true statements made by untrustworthy informants and strange clocks that sometimes display the correct time while running backwards. Finally, we show that in virtue of employing the paradox-free subjunctive conditionals codified by Relevance Logic theorists instead of the paradox-laden subjunctive conditionals codified by Robert Stalnaker and David Lewis.

Sherrilyn Roush’s Tracking Truth (2005) is an impressive, precision-crafted work. Although it sets out to rehabilitate the epistemological theory of Robert Nozick’s "Philosophical Explanations" (1981), its departures from Nozick’s line are extensive and original enough that it should be regarded as a distinct form of epistemological externalism. Roush’s mission is to develop an externalism that averts the problems and counterexamples encountered not only by Nozick’s theory but by other varieties of externalism as well. Roush advances both a theory of (...) knowledge and a theory of evidence; I focus entirely on knowledge. I shall pinpoint a few respects in which Roush’s theory is not wholly successful. In particular, it works less well than process- (or method-) oriented externalisms like process reliabilism. (shrink)

It is known that the Restricted Predicate Calculus can be embedded in an elementary theory, the signature of which consists of exactly two equivalences. Some special models for the mentioned theory were constructed to prove this fact. Besides formal adequacy of these models, a question may be posed concerning their conceptual simplicity, "transparency" of interpretations they assigned to the two stated equivalences. In works known to us these interpretations are rather complex, and can be called "technical", serving only the purpose (...) of embedding. We propose a conversion method, which transforms an arbitrary model of RPC into some model of the elementary theory TR, which includes three equivalences. RPC is embeddable in TR, and it appears possible to assign some "natural" interpretations to three equivalences using the "Track of Relation " concept. (shrink)

Abstract How is meaning assigned to those terms in a theory which are remote from direct observational instantiation? Models and analogies play a role, but close examination of theories in high energy physics shows that the design of experimental apparatus also influences the interpretation of such terms. Certain apparatus favours certain kinds of effects, and this affects the way mathematical theories are interpreted. In particular track producing apparatus becomes involved with theories in which photonic terms are picked (...) out in the theory. A further conceptual constraint is thus introduced. It is argued that this situation favours the interpretation of dispositional properties as affordances rather than as simple dispositions. (shrink)

We propose a new model for forming and revising beliefs about unknown probabilities. To go beyond what is known with certainty and represent the agent’s beliefs about probability, we consider a plausibility map, associating to each possible distribution a plausibility ranking. Beliefs are defined as in Belief Revision Theory, in terms of truth in the most plausible worlds. We consider two forms of conditioning or belief update, corresponding to the acquisition of two types of information: learning observable evidence obtained by (...) repeated sampling from the unknown distribution; and learning higher-order information about the distribution. The first changes only the plausibility map, but leaves the given set of possible distributions essentially unchanged; the second rules out some distributions, thus shrinking the set of possibilities, without changing their plausibility ordering.. We look at stability of beliefs under either of these types of learning, defining two related notions, as well as a measure of the verisimilitude of a given plausibility model. We prove a number of convergence results, showing how our agent’s beliefs track the true probability after repeated sampling, and how she eventually gains in a sense knowledge of that true probability. Finally, we sketch the contours of a dynamic doxastic logic for statistical learning. (shrink)

Like moths attracted to a bright light, philosophers are drawn to glitz. So in discussing the notions of ‘gauge’, ‘gauge freedom’, and ‘gauge theories’, they have tended to focus on examples such as Yang–Mills theories and on the mathematical apparatus of fibre bundles. But while Yang–Mills theories are crucial to modern elementary particle physics, they are only a special case of a much broader class of gauge theories. And while the fibre bundle apparatus turned out, in (...) retrospect, to be the right formalism to illuminate the structure of Yang–Mills theories, the strength of this apparatus is also its weakness: the fibre bundle formalism is very flexible and general, and, as such, fibre bundles can be seen lurking under, over, and around every bush. What is needed is an explanation of what the relevant bundle structure is and how it arises, especially for theories that are not initially formulated in fibre bundle language. Here I will describe an approach that grows out of the conviction that, at least for theories that can be written in Lagrangian/Hamiltonian form, gauge freedom arises precisely when there are Lagrangian/Hamiltonian constraints of an appropriate character. This conviction is shared, if only tacitly, by that segment of the physics community that works on constrained Hamiltonian systems. (shrink)

Argues that the core of the concept of knowledge is true belief plus some property indicative of true belief and that there is no detailed answer to the query ‘and what property is that?’ The Nozick–Dretske counterfactual analysis, Alvin Goldman's causal theory, reliabilism, and the justified true belief account are all good approximations to the concept of knowledge, for, in each case, there is justification for the addition made to the minimal concept. This justification arises not so much from the (...) concept of knowledge itself as from certain very general beliefs we hold about the world. Thus, when the conditions laid down in the minimal concept are satisfied, it will almost always be believed that the conditions of the above theories are satisfied too. (shrink)

While philosophers of perception develop representational theories of olfactory experiences, there are doubts regarding whether features of olfactory perception can be accommodated within the representationalist framework. In particular, it is argued that the function of olfaction is not to represent stimuli but rather to evaluate it. The paper claims that the major representational accounts of olfaction have problems in accommodating the evaluative aspects of olfactory phenomenology. However, an alternative position, named “olfactory evaluativism,” is proposed which is free of these (...) problems and may serve as a foundation for further developments of representational approach to olfactory experiences.

In recent years, data-driven approaches to chronic pain care have increased dramatically. However, people living with chronic pain are ambivalent about datafication practices. Drawing on in-depth interviews with individuals living with chronic pain, I discuss and analyze this ambivalence. On the one hand, participants imbibe the promissory rhetoric of data as that which may organize and control the body in pain. On the other hand, they dismiss and critique the type of data collected. This micro-level analysis of the pain (...) class='Hi'>tracking experience illuminates a tension between datafication and chronic pain. Datafication demands that the patient relay information about their body that is free of ambiguity. However, chronic pain is ambiguous and full of paradox. This article illuminates the emotional chasm between datafication enthusiasts and chronic pain patients who track their pain and suggests that such enthusiasm may lead to bad faith. (shrink)

Scientific realism is the optimistic view that modern science is on the right track: that the world really is the way our best scientific theories describe it. In his book, Stathis Psillos gives us a detailed and comprehensive study which restores the intuitive plausibility of scientific realism. We see that throughout the twentieth century, scientific realism has been challenged by philosophical positions from all angles: from reductive empiricism, to instrumentalism and to modern sceptical empiricism. _Scientific Realism_ explains that the (...) history of science does not undermine the arguments for scientific realism, but instead makes it reasonable to accept scientific realism as the best philosophical account of science, its empirical success, its progress and its practice. Anyone wishing to gain a deeper understanding of the state of modern science and why scientific realism is plausible, should read this book. (shrink)

In this paper, I examine Azzouni's tracking requirement and its use as a normative constraint on theories about objects which we take as real.

In his ‘Gundersen on Counterfactuals and Tracking’ (Sats – Nordic Journal of Philosophy: 2005), Joshua Smith presents some very interesting points of criticism relating to my ‘Outline of a New Semantic for Counterfactuals’ (Pacific Philosophical Quarterly 85: 2004). In the following I'll do three things. I will briefly summarise the central theses from that paper and sketch the arguments that I take to support these theses. Then I will discuss Smith's objections; identify some points of agreement – but also (...) some points of disagreements – and try to shed some more light on certain central views of mine that might otherwise give rise to objections akin to those offered by Smith. Finally I will pursue a bit further a line of enquiry taken up by Smith. The central question here is to which extent, and why, tracking (and safety) theories of knowledge are vulnerable to Gettier cases. (shrink)

The simplicity of a theory seems closely related to how well the theory summarizes individual data points. Think, for example, of classic curve-fitting. It is easy to get perfect data-fit with a ‘‘theory’’ that simply lists each point of data, but such a theory is maximally unsimple (for the data-fit). The simple theory suggests instead that there is one underlying curve that summarizes this data, and we usually prefer such a theory even at some expense in data-fit. In general, it (...) seems, theorizing involves looking for regularities or patterns in our experience, and such regularities are interesting to us because they summarize how our experience goes. We could list all the ravens we’ve encountered, and their colors, or we could summarize.. (shrink)

The lottery problem is often regarded as a successful counterexample to reliabilism. The process of forming your true belief that your ticket has lost solely on the basis of considering the odds is, from a purely probabilistic viewpoint, much more reliable than the process of forming a true belief that you have lost by reading the results in a normally reliable newspaper. Reliabilism thus seems forced, counterintuitively, to count the former process as knowledge if it so counts the latter process. (...) -/- I offer a theory of empirical knowledge which, while being recognizably reliabilist, restricts empirical knowledge to cases in which the fact that p and the belief that p are causally connected. I show that this form of reliabilism solves the lottery problem, avoids the problems that beset the causal theory of knowledge, and show how it handles a number of problematic cases in the recent literature.

Sharon Street’s 2006 article “A Darwinian Dilemma for Realist Theories of Value” challenges the epistemological pretensions of the moral realist, of the nonnaturalist in particular. Given that “Evolutionary forces have played a tremendous role in shaping the content of human evaluative attitudes” – why should one suppose such attitudes and concomitant beliefs would track an independent moral reality? Especially since, on a nonnaturalist view, moral truth is causally inert. I abstract a logical skeleton of Street’s argument and, with its (...) aid, focus on problematic assumptions regarding the (a)causality of moral truth. It emerges that there are acquired causal powers that compensate for the intrinsic impotence of moral truth, as well as two distinct levels at which truth-tracking might occur. I argue that while evolution’s selective forces do not track moral truth, that does not imply individual organisms could not have evolved that capability. -/- . (shrink)

A basic challenge to naturalistic moral realism is that, even if moral properties existed, there would be no way to naturalistically represent or track them. Here, the basic structure for a tracking account of moral epistemology is given in empirically respectable terms, based on a eudaimonist conception of morality. The goal is to show how this form of moral realism can be seen as consistent with the details of evolutionary biology as well as being amenable to the most current (...) understanding of representationalist or correspondence theories of truth.

The paradigm of referent tracking is based on a realist presupposition which rejects so-called negative entities (congenital absent nipple, and the like) as spurious. How, then, can a referent tracking-based Electronic Health Record deal with what are standardly called ‘negative findings’? To answer this question we carried out an analysis of some 748 sentences drawn from patient charts and containing some form of negation. Our analysis shows that to deal with these sentences we need to introduce a new (...) ontological relationship between a particular and a universal, which holds when no instance of the universal has a specific qualified ontological relation with the particular. This relation is found to be able to accommodate nearly all occurrences of negative findings in the examined sample, in ways which involve no reference to negative entities. (shrink)
