Infectious disease outbreaks in residential care are complex to manage and difficult to control. Research in this setting that includes individuals who lack capacity must conform to national legislation. We report here on our study that is investigating outbreaks of scabies, an itchy skin infection, in the residential care setting in the southeast of England. There appears to be a gap in legislative advice regarding the inclusion of people who lack capacity in research that takes place during time-limited acute scenarios (...) such as outbreaks. We received inconsistent advice from experts regarding, in particular, the role of nominated consultees. There is a potential inequality for vulnerable populations who cannot themselves provide informed consent in terms of their access to participation in a range of health-related research. (shrink)

Can self-locating beliefs be relevant to non-self-locating claims? Traditional Bayesian modeling techniques have trouble answering this question because their updating rule fails when applied to situations involving contextsensitivity. This essay develops a fully general framework for modeling stories involving context-sensitive claims. The key innovations are a revised conditionalization rule and a principle relating models of the same story with different modeling languages. The essay then applies the modeling framework to the Sleeping Beauty Problem, showing that when Beauty awakens her degree (...) of belief in heads should be one-third. This demonstrates that it can be rational for an agent who gains only self-locating beliefs between two times to alter her degree of belief in a non-self-locating claim. (shrink)

“Double-halfers” think that throughout the Sleeping Beauty Problem, Beauty should keep her credence that a fair coin flip came up heads equal to 1/2. I introduce a new wrinkle to the problem that shows even double-halfers can't keep Beauty's credences equal to the objective chances for all coin-flip propositions. This leaves no way to deny that self-locating information generates an unexpected kind of inadmissible evidence.

ObjectiveHead and neck cancer treatments are known to significantly affect functionality and appearance, leading to an increased risk for body image disturbances. Yet, few longitudinal studies exist to examine body image in these patients. Based on a conceptual model, the current study aimed to determine, in patients newly diagnosed with HNC: the prevalence, level, and course of body image concerns; correlates of upon cancer diagnosis body image concerns; predictors of immediate post-treatment body image concerns; and association between body image concerns (...) and levels of anxiety, depression, suicidal ideation, support, and alcohol and drug misuse.MethodsTwo hundred and twenty-three, newly diagnosed with a primary HNC were assessed using structured clinical interviews and psychometric measures at three, and 6 months after diagnosis. Primary outcome was 3-month, as it was most salient to body image disturbance. Multiple linear regression analyses were conducted on the potential body image predictors, based on the model.ResultsSixty-eight percent of patients with HNC presented some level of body image concerns. Body image concerns at baseline and post-treatment were significantly related and significantly increased from pre- to post-treatment. Immediately post-treatment, 89% presented some level of body image concerns. Correlates of body image concerns in patients with HNC at baseline included: physical symptom burden, difficulties with communication and eating, coping with the cancer diagnosis using denial, suicidal ideation, and having had a past anxiety diagnosis. When controlling for sociodemographic and medical variables, body image concerns in patients with HNC in the immediate post-treatment were predicted by: baseline body image, physical symptom burden, and neuroticism.ConclusionThis longitudinal study helps identify patients more susceptible to experience body image disturbance following head and neck cancer. Clinicians ought to pay special attention to body image concerns upon cancer diagnosis, physical symptom burden, and neuroticism, and may want to target these factors in future preventive interventions.

This study investigated the relationship between concussions and medication adherence among 247 adults experiencing homelessness in Oklahoma City, Oklahoma, who were prescribed medication for a psychiatric disorder. Participants were asked whether they had “ever experienced a blow to the head that caused a concussion,” and medication adherence was measured by asking participants whether they had taken their psychiatric medication yesterday. The data were analyzed using univariate and multivariable logistic regressions. Results showed that more than half of the sample had (...) a concussion history, and homeless adults with a concussion history had higher odds of non-adherence to psychiatric medications compared with those who reported no concussion history [OR = 2.13 ]. Findings suggest that medication non-adherence is associated with incurred concussions. Raising awareness among service providers of the relationship between traumatic brain injury and medication adherence may increase efforts to improve adherence in this underserved population.

There are no established conventions for, and few examples of, indexing visual material on the basis of its form. Most image databases use keywords to describe the form or function, and access data by text-based retrieval of these keywords. An image-based approach would order the data by appearance, e.g. Shepherd (1971) and Dreyfuss (1972). A taxonomy must be created in order to apply this technique to a new data set. Previous applications have been aided by certain limiting factors on the (...) possible range of images indexed thus providing the key to a taxonomy, e.g. international pictorial signs in Dreyfuss. A fundamental principle which may be inferred from these studies is that the taxonomy needs to be related to the needs of the user, and not solely to abstract features of design. This is reflected in guidelines issued by the UK organisation The Society of Indexers. The studies also suggest the need for several approaches to classification within the same data set, e.g Dreyfuss, in which signs are located under more than one heading. (shrink)

In his paper, "Free Choice, Incommensurable Goods and the Self-Refutation of Determinism,"' Joseph Boyle seeks to show how the argument for the self-refutation of determinism - first articulated over twenty-five years ago - is an argument whose force depends on (first) a proper understanding of just what free choice is, and (secondly) a proper understanding of how free choice is a principle of moral responsibility. According to Boyle, a person can make a genuinely free choice only if he is presented (...) with alternative options that are incommensurable in their goodness or desirability. If the goodness or desirability of alternative options could be commensurated, or compared in accordance with some common standard, then it would be possible in principle for a person to determine which of the two options offered more, and which offered less, of the same sort of good represented by the two options. But if this sort of commensuration or comparison were possible, according to Boyle, then there would really be no need to choose. Rather, the only task that would have to be performed in order to determine the person's selection among alternative options would be the task clarifying or calculating which of the alternative options offered most fully what it is that makes both options desirable in the first place. Once the clarification or calculation is done, there would be no need-and in fact, no possibility--of really choosing: the calculation alone would settle which option is the best option, and thus which option is to be selected. Now if genuinely free choice requires that the choosing person be presented with options that are incommensurable in goodness or desirability, then it also seems to be the case that genuine choice-and the moral responsibility that goes along with it-requires that the person be presented with alternative possibilities from which to choose. And yet some compatibilist thinkers have held that moral responsibility does not really require the presence of alternative possibilities. In particular, Harry G. Frankfurt has sought to show (by means of counter-example) that a person can be a moral agent and morally responsible, even if the person did not, in fact, have any alternative possibilities available to him (that is, even if the person could not have done otherwise). Frankfurt's counter-example offers a direct challenge to the sort of incompatibilism that Boyle seeks to defend; and so Boyle is quite right to address Frankfurt head-on. For if Frankfurt is right, then it is erroneous to hold "the principle of alternative possibilities" (the principle that a person can be morally responsible for what he has done, only if he had alternative possibilities, or only if he could have done otherwise). But if it is erroneous to hold the principle of alternative possibilities, then it also seems erroneous to hold the more robust position that Boyle wishes to defend: namely, the position that moral responsibility requires not only alternative possibilities, but also alternative possibilities representing options that are incommensurable in their goodness.

Most science requires applied mathematics. This truism underlies the Quine-Putnam indispensability argument: we cannot be mathematical nominalists without rejecting whole swaths of good science that are seamlessly linked with mathematics. One style of response (e.g. Field’s program) accepts the challenge head-on and attempts to show how to do science without mathematics. There is some consensus that the response fails because the nominalistic apparatus deployed either is not extendible to all of mathematical physics or is merely a deft reconstrual equivalent (...) to standard mathematics. A second style of response (suggested, e.g., by Balaguer and Maddy) denies that indispensability entails realism: when we mathematize a physical problem we treat its physical content as if it were the mathematical representation; provided the two are sufficiently similar, we can use the mathematics to draw conclusions about the physics; even if we cannot represent physical facts without mathematical tools, as-if-fictionalism is reasonable. In this paper I argue that uses of mathematics in science reach deeper than is appreciated by this second response and, indeed, in the more general literature. More specifically, our confidence that we can use the mathematics to draw conclusions about the physics itself depends on mathematics. If the mathematical premises we employ in concluding that a certain application is trustworthy are false, we may lack a justification for supposing that the application will reliably lead us from correct input to correct output. For example, solutions to many physical problems require the determination of a function satisfying a differential equation. Sometimes (e.g., if the differential equation is linear) the existence of a solution for initial value problems can be established directly; where direct methods fail, the existence of a solution must be established indirectly, generally by constructing a sequence of functions that converges to a limit function that satisfies the initial value problem. Moreover, the solution often cannot be evaluated by analytic methods, and scientists must rely on finite element numerical methods to approximate the solution. Mathematical analysis of errors provides further useful information governing the choice of approximation method and of the step size and number of elements needed for the approximation to reach a desired precision. Mathematical physicists rely on the background mathematical theories (e.g., theory of differential equations) presupposed in proving the existence of the solutions and approximating them. It is difficult to see how they could do this while adding the fictionalist disclaimer, “But, you know, I don’t believe any of the mathematics I’m using”. It is difficult to see how a fictionalist pursuing the second strategy can account for the soundness of mathematical reasoning in mathematical physics and elsewhere in the sciences. The paper will fill out this argument by appeal to examples and attempt to make clear (a) how mathematics is indispensable to understanding – and thus underwriting our confidence in – applications that would otherwise be shaky approximations and idealizations and (b) how this role is difficult to square with fictionalism.

A common objection to sense-datum theories of perception is that they cannot give an adequate account of the fact that introspection indicates that our sensory experiences are directed on, or are about, the mind-independent entities in the world around us, that our sense experience is transparent to the world. In this paper I point out that the main force of this claim is to point out an explanatory challenge to sense-datum theories.

The disjunctive theory of perception claims that we should understand statements about how things appear to a perceiver to be equivalent to statements of a disjunction that either one is perceiving such and such or one is suffering an illusion (or hallucination); and that such statements are not to be viewed as introducing a report of a distinctive mental event or state common to these various disjoint situations. When Michael Hinton first introduced the idea, he suggested that the burden (...) of proof or disproof lay with his opponent, that what was needed was to show that our talk of how things look or appear to one..

This article defends the Fixed Point Thesis: that it is always a rational mistake to have false beliefs about the requirements of rationality. The Fixed Point Thesis is inspired by logical omniscience requirements in formal epistemology. It argues to the Fixed Point Thesis from the Akratic Principle: that rationality forbids having an attitude while believing that attitude is rationally forbidden. It then draws out surprising consequences of the Fixed Point Thesis, for instance that certain kinds of a priori justification are (...) indefeasible and that misleading all-things-considered evidence about rational requirements is impossible. Finally, the Fixed Point Thesis is applied to defend the Right Reasons position on peer disagreement, according to which an agent who has drawn the correct conclusion from her evidence should retain belief in that conclusion even in the face of disagreeing peers.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Platonopolis: Platonic Political Philosophy in Late AntiquityMichael F. WagnerDominic J. O'Meara. Platonopolis: Platonic Political Philosophy in Late Antiquity. Oxford: Clarendon Press, 2003. Pp. xi + 249. Cloth, $55.00.Porphyry tells of Plotinus's failed petition to emperor Gallienus to (re)establish a "city of philosophers" conformed to Plato's laws, named Platonopolis (Vit. Plo.12). O'Meara here articulates primary themes and developments in philosophical political thought in the classical Neoplatonic period, from Plotinus's (...) day in the mid-third century into the sixth century. Concurrently, he addresses head on "the conventional view that the Platonist philosophers of Late Antiquity had no political philosophy" (3). This view exemplifies the more general perspective that the Neoplatonists were simply disinterested in this-worldly affairs in lieu of "an immaterial world... our true 'homeland,' where we can at last attain the good we desire" (3). Consequently, O'Meara provides both a unique study of an important [End Page 205] topic and a compelling case for a more complete, balanced understanding of Neoplatonic other-worldly-ness. O'Meara's study covers key figures from four main groups of (neo)Platonists: Plotinus and his students; the schools in Syria and Asia Minor inspired by Iamblichus; the Athenian school (Plutarch, Proclus, Damascius et al.); and the Alexandrian school (Hyapatia, Philoponus, Olympiodorus et al.). He organizes his investigation (chapters) into three Parts.The pivotal concept in O'Meara's two-pronged endeavor is divinization - "assimilation and unification, as far as possible, to god" (31, Proclus) - a concept whose meaning for classical Neoplatonists ranges from "becoming a god" to "imitating some form of divine life, in one way or another" (31). Part I focuses on the Neoplatonists' shared association of a human soul's divinization with virtue-osity [my jargon], beginning with Plotinus's distinction between political virtue(s) and purification—or purificatory virtue(s). O'Meara emphasizes the relevance of the resulting "scale of virtues" to a life of continued activity—for example explicating Plotinus's denial that a "purified" soul is somehow exempt from the rightness-of-acting expected of the politically virtuous soul: rather, "reaching higher principles and different measures he will act [directly, immediately] according to these" (43, En. I,2,7).Another organizing theme as O'Meara's investigations proceed beyond Plotinus is the significance of the increasing complexities of particular Neoplatonic metaphysical systems, and so also of their moral systems - e.g. their "scales of virtue." Part I also articulates related attempts (beginning with Porphyry and Iamblichus) to articulate programs of moral and philosophical study - i.e. a related "scale of sciences." Of special note here are proposals by some Neoplatonists to divide the "practical sciences" associated on this scale with political virtuousness into legislative science(s) and judicial science (56). Implicit in the Neoplatonic scale(s) of virtue(s) was the thesis that as one progresses towards divinization "lower" virtue-osity is not transcended in the sense of lost or dismissed but rather it is included or incorporated into a higher form. Arguably, "lower" sciences are likewise not merely aids or stepping-stones towards something "higher," but genuine topoi of study and knowledge in their own right.Part II is the true heart of O'Meara's outstanding scholarly and philosophical inquiry. Here is where he fulfills his intent to discern a substantive tradition of political philosophy and to articulate its key themes and concepts. Though he associates this part of his investigation with Plato's conceit of the philosopher's return to the cave, he immediately parses this "descent" as a "divinization of political life through philosophy" (71). He articulates various Neoplatonists' approaches to questions inspired by Plato's cave allegory—e.g. Is the philosopher socially obligated to "return"? Could s/he then still be happy? (His investigation here does seem to overlook Neoplatonic conceptions of choice, volition, or will as these might pertain to such questions.) O'Meara recognizes, however, that the more fundamental link between Neoplatonic metaphysics and Neoplatonic ethical-political thought derives from Plotinus's conception "of fecundity, of an [overflowing] abundance" (74) in his highest One, and so in a soul assimilated to It. In Proclus's formulation: "that which... (shrink)

Disjunctivism about perceptual appearances, as I conceive of it, is a theory which seeks to preserve a naïve realist conception of veridical perception in the light of the challenge from the argument from hallucination. The naïve realist claims that some sensory experiences are relations to mind-independent objects. That is to say, taking experiences to be episodes or events, the naïve realist supposes that some such episodes have as constituents mind-independent objects. In turn, the disjunctivist claims that in a case of (...) veridical perception like this very kind of experience that you now have, the experiential episode you enjoy is of a kind which could not be occurring were you having an hallucination. The common strategy of arguments from hallucination set out to show that certain things are true of hallucinations, and hence must be true of perceptions. For example, it is argued that hallucinations must have non-physical objects of awareness, or that such states are not relations to anything at all, but are at best seeming relations to objects. In insisting that veridical perceptual experience is of a distinct kind from hallucination, the disjunctivist denies that any of these conceptions of hallucination challenges our conception of veridical perceptions as relations to mind-independent objects. More specifically, I assume that the disjunctivist advocates naïve realism because they think that this position best articulates how sensory experience seems to us to be just through reflection. If the disjunctivist is correct in this contention, then anyone who accepts the conclusion of the argument from hallucination must also accept that the nature of sensory experience is other than it seems to us to be. In turn, one may complain that any such error theory is liable to lead to sceptical consequences. A Humean scepticism about the senses launches a challenge about our knowledge of the world through questioning the conception we have of what sense experience is, and how it can provide knowledge of the world.

Michael G. Titelbaum presents a new Bayesian framework for modeling rational degrees of belief—the first of its kind to represent rational requirements on agents who undergo certainty loss.

In this chapter, we explore the role of habit in giving shape to conscious experience and importantly to our pre-reflective awareness of ourselves which includes the sense of mineness that accompanies our conscious experience. For the most part, discussions in philosophy of mind and phenomenology concerning pre-reflective self-awareness are focused on determining the relationship between phenomenal consciousness and selfhood. For this reason perhaps, the existence of pre-reflective self-awareness is usually appealed to as evidence for a form of selfhood that appears (...) within conscious experience as a component of its synchronic unity. In this chapter, however, we will concern ourselves with the pre-reflective sense of ourselves that appears in conscious experience as it pertains to the diachronic unity of the self—that is the sense of a unitary self as existing over the course of multiple episodic experiences. Our aim is to provide a phenomenological account of the relationship between the minimal, pre-reflective sense of self and what is often termed the ‘narrative self.’ We will argue that habits play a role in preserving the significance of our past in our present experience and in unifying our experience as a self for whom the world is present across disparate episodes of experience.

Different people reason differently, which means that sometimes they reach different conclusions from the same evidence. We maintain that this is not only natural, but rational. In this essay we explore the epistemology of that state of affairs. First we will canvass arguments for and against the claim that rational methods of reasoning must always reach the same conclusions from the same evidence. Then we will consider whether the acknowledgment that people have divergent rational reasoning methods should undermine one’s confidence (...) in one’s own reasoning. Finally we will explore how agents who employ distinct yet equally rational methods of reasoning should respond to interactions with the products of each others’ reasoning. We find that the epistemology of multiple reasoning methods has been misunderstood by a number of authors writing on epistemic permissiveness and peer disagreement. (shrink)

Listening to someone from some distance in a crowded room you may experience the following phenomenon: when looking at them speak, you may both hear and see where the source of the sounds is; but when your eyes are turned elsewhere, you may no longer be able to detect exactly where the voice must be coming from. With your eyes again fixed on the speaker, and the movement of her lips a clear sense of the source of the sound will (...) return. This ‘ventriloquist’ effect reflects the ways in which visual cognition can dominate auditory perception. And this phenomenological observation is one that you can verify or disconfirm in your own case just by the slightest reflection on what it is like for you to listen to someone with or without visual contact with them.

Comparisons, and by that I mean the hunt for essential similarities or at least serious family resemblances, between the ethical views of Western and non-Western thinkers have been a staple of comparative philosophy for quite some time now. Some of these comparisons, such as between the views of Aristotle and Confucius, seem especially apt and revealing. However, I’ve often wondered whether Western “ethical theory”—virtue ethics, deontology, or consequentialism—is always the best lens through which to approach non-Western ethical thought. Particularly when (...) the discussion has turned to Buddhism and Buddhist ethics, theories of this sort at best seem to have an uncertain application. This is not to say that .. (shrink)

Book description: The capacity to represent and think about time is one of the most fundamental and least understood aspects of human cognition and consciousness. This book throws new light on central issues in the study of the mind by uniting, for the first time, psychological and philosophical approaches dealing with the connection between temporal representation and memory. Fifteen specially written essays by leading psychologists and philosophers investigate the way in which time is represented in memory, and the role memory (...) plays in our ability to reason about time. They offer insights into current theories of memory processes and of the mechanisms and cognitive abilities underlying temporal judgements, and draw out fundamental issues concerning the phenomenology and epistemology of memory and our understanding of time. The chapters are arranged into four sections, each focused on one area of current research: Keeping Track of Time, and Temporal Representation; Memory, Awareness and the Past; Memory and Experience; Knowledge and the Past: The Epistemology and Metaphysics of Time. A general introduction gives an overview of the topics discussed and makes explicit central themes which unify the different philosophical and psychological approaches. (shrink)

Begins by explaining then proving a generalized language dependence result similar to Goodman's "grue" problem. I then use this result to cast doubt on the existence of an objective evidential favoring relation (such as "the evidence confirms one hypothesis over another," "the evidence provides more reason to believe one hypothesis over the other," "the evidence justifies one hypothesis over the other," etc.). Once we understand what language dependence tells us about evidential favoring, our options are an implausibly strong conception of (...) the a priori, a hard externalism on which agents are unable to determine what their evidence favors, or a subjectivist view that makes evidential favoring relative to features of the agent.

In der vorliegenden Arbeit soll die These mitsamt den sich aus ihr ergebenden Konsequenzen etabliert werden, dass die Disziplin Gerechtigkeitstheorie durch Entwicklungen in der Disziplin Erkenntnistheorie in dem Sinne beeinflusst wird, dass erstere sich von letzterer Anregungen im grundsätzlichen methodischen Vorgehen holt. Diese These soll sowohl unter Bezug auf allgemeine Argumente plausibilisiert als auch durch eine Rekonstruktion gerechtigkeitstheoretischer Ansätze aus erkenntnistheoretisch informierter Perspektive am konkreten Material belegt werden. Eine Konsequenz, die sich aus dieser These ableiten lässt, ist die Vorhersage, dass (...) die beiden bis anhin vorherrschenden Paradigmen innerhalb der Gerechtigkeitstheorie - Neoaristotelismus und Neokantianismus - nur schwer in der Lage sein werden, ihre jeweilige Schwäche, nämlich Kulturrelativismus respektive leeren Universalismus, zu überwinden, weil diese Schwäche eine notwendige Folge aus ihrer Anlehnung an die ihnen jeweils zugrunde liegende Erkenntnistheorie darstellt und somit auf basaler Ebene der Theorie verortet ist. Eine andere Konsequenz besteht darin, dass es auf Basis dieser These möglich wird, zwei aktuelle, bislang aber nur selten miteinander assoziierte gerechtigkeitstheoretische Ansätze, die sich beide gegen die vorherrschenden Paradigmen wenden - nämlich der Ansatz Amartya Sens und derjenige Axel Honneths -, als ein und derselben philosophischen Theorietradition zugehörig auszuweisen: dem Pragmatismus. Unter explizitem Anschluss an selbige Theorietradition sollen diese beiden gerechtigkeitstheoretischen Ansätze zudem zu einem Ansatz weiterentwickelt werden, der als "Gerechtigkeitstheorie als historischer Experimentalismus" bezeichnet wird.

The Sleeping Beauty Problem attracts so much attention because it connects to a wide variety of unresolved issues in formal epistemology, decision theory, and the philosophy of science.

Abstract. Richard Feldman’s Uniqueness Thesis holds that “a body of evidence justifies at most one proposition out of a competing set of proposi- tions”. The opposing position, permissivism, allows distinct rational agents to adopt differing attitudes towards a proposition given the same body of evidence. We assess various motivations that have been offered for Uniqueness, including: concerns about achieving consensus, a strong form of evidentialism, worries about epistemically arbitrary influences on belief, a focus on truth-conduciveness, and consequences for peer disagreement. (...) We argue that each of these motivations either misunderstands the commitments of permissivism or is question-begging. Better understanding permissivism makes it a much more plausible position.

Recent discussion of Vogel-style “bootstrapping” scenarios suggests that they provide counterexamples to a wide variety of epistemological theories. Yet it remains unclear why it’s bad for a theory to permit bootstrapping, or even exactly what counts as a bootstrapping case. Going back to Vogel's original bootstrapping example, I note that an agent who could gain justification through the method Vogel describes would have available a “no-lose investigation”: an investigation that can justify a proposition but has no possibility of undermining it. (...) The main suggestion of this article is that an epistemological theory should not permit no-lose investigations. I identify necessary and sufficient conditions for such investigations, then explore epistemological theories that rule them out. If we want to avoid both skepticism and no-lose investigations, we must eschew either Closure or epistemic externalism. (shrink)

I argue that given standard deontic logic, wide-scope rational requirements entail narrow-scope rational requirements. In particular, the widely-embraced Enkratic Principle entails that if a particular combination of attitudes is rationally forbidden, it is also rationally forbidden to believe that that combination of attitudes is required.

Roger White argued for a principle of indifference. Hart and Titelbaum showed that White’s argument relied on an intuition about conditioning on biconditionals that, while widely shared, is incorrect. Hawthorne, Landes, Wallmann, and Williamson argue for a principle of indifference. Remarkably, their argument relies on the same faulty intuition. We explain their intuition, explain why it’s faulty, and show how it generates their principle of indifference. 1Introduction 2El Caminos and Indifference 2.1Overview 2.2Fins and antennas 2.3HLWW in the example 2.4The restrictiveness (...) of Condition 2 2.5Summary 3The Specifics of HLWW s Argument 3.1Mapping their conditions to our equations 3.2HLWW’s responses to objections.

A plea: If you're going to propose a Bayesian framework for updating self-locating degrees of belief, please read this piece first. I've tried to survey all the extant formalisms, group them by their general approach, then describe challenges faced by every formalism employing a given approach. Hopefully this survey will prevent further instances of authors' re-inventing updating rules already proposed elsewhere in the literature.

Metaethicists have recently devoted a great deal of attention to questions about when a fact counts as a reason for or against a particular conclusion, and how such reasons interact. Chapter 9 asks a broader question: When a set of facts counts in favor of some conclusion, is that always because at least one of those facts is a reason for that conclusion? Examples are offered in which a set supports a conclusion without any fact in that set’s being a (...) reason for. The chapter then assesses the significance of such examples for philosophical methodology, the ‘reasons-first’ program, and metanormative realism. (shrink)
