_Happy Lives, Good Lives_ offers a thorough introduction to a variety of perspectives on happiness. Among the questions at issue: Is happiness only a state of mind, or is it something more? Is it the same for everyone? Is it under our control, and if so, to what extent? Can we be mistaken about whether we are happy? What role, if any, does happiness play in living a good life? Is it sometimes morally wrong to pursue happiness? Should governments promote (...) happiness through public policy? Asking and answering these questions is worthwhile not only as an intellectual exercise, but also as a means of gaining practical insight into how best to pursue a happy life. (shrink)

_Theories of Happiness: An Anthology_ introduces readers to many difficult philosophical questions surrounding the concept of happiness. With historical and contemporary readings in philosophy, psychology, and the social sciences, the anthology reflects a dialogue between ideas, providing for a rich conversation that brings out the key insights and strengths of several competing views. Each of the included readings is contextualized by the editors and situated to speak to the larger issues, including the value of happiness and its connection to well-being, (...) the relationship of happiness to morality, whether happiness can be accurately and meaningfully measured, and whether there are universal standards for a happy life.

As a philosophy professor, one of my central goals is to teach students to think critically. However, one difficulty with determining whether critical thinking can be taught, or even measured, is that there is widespread disagreement over what critical thinking actually is. Here, I reflect on several conceptions of critical thinking, subjecting them to critical scrutiny. I also distinguish critical thinking from other forms of mental processes with which it is often conflated. Next, I present my own conception of critical (...) thinking, wherein it fundamentally consists in acquiring, developing, and exercising the ability to grasp inferential connections holding between statements. Finally, given this account of critical thinking, and given recent studies in cognitive science, I suggest the most effective means for teaching students to think critically. (shrink)

In this paper, we present an especially effective tool for helping students to learn and apply the skills of critical reasoning. Our Writing Portfolio Project is a set of nine progressively staged writing assignments that guide students through the formulation and development of an argumentative paper. The set of assignments are designed to reinforce, reintroduce, and repeat critical reasoning skills. In this paper, we articulate the potential uses for the Writing Portfolio Project, give a brief explanation of the reasoning behind (...) the format of the project, and indicate ways one might implement the Writing Portfolio Project into one’s curriculum.

This paper discusses an exercise that Alida Liberman facilitated among participants at a Teaching and Learning workshop sponsored by the American Association of Philosophy Teachers (AAPT) aimed at helping instructors become more learner-centered in their pedagogy. The exercise was designed to place participants in the role of inadequately supported learners by asking them to fold an origami crane with varying levels of instruction and feedback. The failure of many participants to successfully fold cranes functioned as a striking analogy for student (...) failures to learn without explicit how-to instruction, goal-directed practice, and frequent, targeted feedback. In reflecting on the activity, participants developed strategies to become more learner-centered and to better support student success. This paper explains the origami exercise and the lessons it illustrates, and discusses how the lessons learned from the exercise can translate into specific tangible strategies for the classroom.

This paper defends reliabilism against the classic demon world victim thought experiment. In doing so, I underscore two of its key alleged intuitions. I then articulate a host of varied responses open to the reliabilist, arguing that these readily available responses provide the reliabilist with a way to either accommodate or reject these initial intuitions about the demon world victim thought experiment, and in a way consistent with reliabilism. Thus, I conclude that the demon world thought experiment does not undercut (...) reliability as the hallmark of epistemic justification. (shrink)

Semantic externalism holds that the content of at least some of our thoughts is partly constituted by external factors. Accordingly, it leads to the unintuitive consequence that we must then often be mistaken in what we are thinking, and any kind of claim of privileged access must be given up. Those who deny that semantic externalists can retain any account of self-knowledge are ‘incompatibilists’, while those who defend the compatibility of self-knowledge with semantic externalism are ‘compatibilists’. This paper examines the (...) claim of compatibilism, focusing on Burge’s “Slow Switching Argument” and Boghossian’s “Objection of Relevant Alternatives”. I argue that compatibilism is false, and that semantic externalism is incompatible with self-knowledge. (shrink)

This paper offers an account of the a priori/a posteriori distinction utilizing the insights of reliabilism, focusing on the inputs to reliable belief-forming processes. Ipropose that a belief possesses a priori justification if it is the result of a reliable belief-producing process whose input is ‘non-sensory’ and the reliability of this process does not ‘causally depend’ on the reliability of a prior process taking in ‘sensory’ input. One of the interesting consequences of this account is in the treatment of introspective (...) knowledge of one’s belief-states; it was classically considered a posteriori, but comes out a priori on this model.

This paper responds to Barnes‟ two main criticisms, that of derivational skepticism and causal asymmetry, and successfully refutes his objections. This paper also defends the plausibility of the unificationist account of scientific explanation because of its ability to render coherent the notion of scientific understanding, focusing in particular on (...) the work by Michael Friedman and Philip Kitcher.

A 16 year old Hodgkin lymphoma patient refuses to have his blood specimen drawn, thus canceling his scheduled oncologic treatment. As a 16 year old, he has no legal standing as an adult. His parents are split over his decision. One supports his right to choose; the other wishes the specimen to be drawn and the chemotherapy reinstated. The physicians at the hospital are seeking legal redress to have the court order the blood specimens to be taken.

It is alleged that the causal inertness of abstract objects and the causal conditions of certain naturalized epistemologies precludes the possibility of mathematical know- ledge. This paper rejects this alleged incompatibility, while also maintaining that the objects of mathematical beliefs are abstract objects, by incorporating a naturalistically acceptable account of ‘rational intuition.’ On this view, rational intuition consists in a non-inferential belief-forming process where the entertaining of propositions or certain contemplations results in true beliefs. This view is free of any (...) conditions incompatible with abstract objects, for the reason that it is not necessary that S stand in some causal relation to the entities in virtue of which p is true. Mathematical intuition is simply one kind of reliable process type, whose inputs are not abstract numbers, but rather, contemplations of abstract numbers. (shrink)

En este trabajo se defiende el fiabilismo frente al experimento mental clásico del "genio maligno". Al hacerlo, enfatizo dos de sus supuestos clave; y después desarrollo una serie de variadas respuestas asequibles al fiabilista, mostrando que las mismas pueden ser útiles para explicar o negar las intuiciones iniciales de la propuesta del "genio maligno", de una manera consistente con el fiabilismo. Mi conclusión es que el experimento del "genio maligno" no socava la fiablidad como el sello distintivo de la justificación (...) epistémica. (shrink)

According to classical arguments, language learning is both facilitated and constrained by cognitive biases. These biases are reflected in linguistic typology—the distribution of linguistic patterns across the world's languages—and can be probed with artificial grammar experiments on child and adult learners. Beginning with a widely successful approach to typology (Optimality Theory), and adapting techniques from computational approaches to statistical learning, we develop a Bayesian model of cognitive biases and show that it accounts for the detailed pattern of results of artificial (...) grammar experiments on noun-phrase word order (Culbertson, Smolensky, & Legendre, 2012). Our proposal has several novel properties that distinguish it from prior work in the domains of linguistic theory, computational cognitive science, and machine learning. This study illustrates how ideas from these domains can be synthesized into a model of language learning in which biases range in strength from hard (absolute) to soft (statistical), and in which language-specific and domain-general biases combine to account for data from the macro-level scale of typological distribution to the micro-level scale of learning by individuals.

Most words in English are ambiguous between different interpretations; words can mean different things in different contexts. We investigate the implications of different types of semantic ambiguity for connectionist models of word recognition. We present a model in which there is competition to activate distributed semantic representations. The model performs well on the task of retrieving the different meanings of ambiguous words, and is able to simulate data reported by Rodd, Gaskell, and Marslen‐Wilson [J. Mem. Lang. 46 (2002) 245] (...) on how semantic ambiguity affects lexical decision performance. In particular, the network shows a disadvantage forwords with multiple unrelated meanings (e.g., bark) that coexists with a benefit for words with multiple related word senses (e.g., twist). The ambiguity disadvantage arises because of interference between the different meanings, while the sense benefit arises because of differences in the structure of the attractor basins formed during learning. Words with few senses develop deep, narrow attractor basins, while words with many senses develop shallow, broad basins. We conclude that the mental representations of word meanings can be modelled as stable states within a high‐dimensional semantic space, and that variations in the meanings of words shape the landscape of this space.

Building on theoretical and empirical insights and applying the thriving theory as the conceptual framework, the authors developed two new teacher-specific scales, namely the Teacher Stress Scale and the Teacher Thriving Scale. The goal of this investigation was to evaluate the psychometric properties of these two scales. Data were collected through an online questionnaire administered to a national sample of 122 participating early childhood teachers teaching in preschool through third grade in 26 states of the United States during the 2020–2021 (...) school year amidst COVID-19. This study revealed some important psychometric results. First, with respect to their internal structures, both the TSS and the TTS appeared to be best represented as bifactorial and trifactorial, respectively. Specifically, the TSS comprised two constructs: Inadequate School-based Support, and Teaching-related Demands; and the TTS encompassed three constructs: Adaptability and Flexibility, Personal Strengths and Professional Growth, and Positive Mindset. Second, the negative correlation between the TSS and the TTS provided discriminant evidence for each other’s construct validity, while the positive correlations between the TTS and six conceptually cognate constructs demonstrated convergent evidence for construct validity for the TTS. Third, both the overall TSS and the overall TTS as well as their subscales exhibited good internal consistency reliability. Fourth, both the overall TSS and the overall TTS also demonstrated test–retest reliability. (shrink)

This article explores sex selective abortion as a form of structural violence within the broader notion of women's ‘protection’ in contemporary India. While SSA tends to be framed more generally within ethical and choice-based frameworks around abortion access and reproductive ‘rights’, and specifically in India around preference for sons as a discriminatory, cultural, technological misogyny, this article argues that sex selective abortion in India needs to be understood as an outcome of broader systemic economic, political and social processes. The deepening (...) of neoliberal values through state policies has impacted significantly on social relations, shaping SSA as a manifestation of structural violence. State-driven policies in India reflect a neoliberal governmentality through state patriarchy that is implicit within the neoliberal developmental, governmental and capitalist paradigm of contemporary India. This article argues that SSA is structurally produced and therefore cannot be remedied through awareness-raising strategies such as beti bachao or financial inclusion as a means to ‘protect’ or ‘save the girl child’. Indeed, it is neoliberal economic forces that actively, though seemingly inadvertently, promote anti-women, sex selective abortion as a reproductive strategy, which is then disciplined through neoliberal governmentality. This highlights SSA as a form of gendered and structural, rather than discriminatory, violence. (shrink)

The use of complementary and alternative medicine (CAM) by US consumers has grown in recent years. CAM therapies often utilize medicinal herbs as part of the treatment process; however, research on US practitioner preferences for medicinal herbs is limited, despite growing concern surrounding the sustainability of wild-harvested medicinal herbs. In order better to understand consumer preferences for this emerging market, a mail survey of US practitioners (licensed acupuncturists) was conducted to examine the importance of five herb attributes in practitioners’ herb (...) selection decisions: (1) country of origin, (2) freshness, (3) production method (organic versus conventional), (4) price, and (5) traceability. The significance of these five traits is investigated using discrete choice analysis, and the implications for US medicinal herb growers are discussed. (shrink)

BackgroundThe COVID-19 pandemic has had a significant impact on the health system worldwide. The organ and tissue donation and transplantation (OTDT) system is no exception and has had to face ethical challenges related to the pandemic, such as risks of infection and resource allocation. In this setting, many Canadian transplant programs halted their activities during the first wave of the pandemic.MethodTo inform future ethical guidelines related to the COVID-19 pandemic or other public health emergencies of international concern, we conducted a (...) literature review to summarize the ethical issues.ResultsThis literature review identified three categories of ethical challenges. The first one describes the general ethical issues and challenges reported by OTDT organizations and transplantation programs, such as risks of COVID-19 transmission and infection to transplant recipients and healthcare professionals during the transplant process, risk of patient waitlist mortality or further resource strain where transplant procedures have been delayed or halted, and resource allocation. The second category describes ethical challenges related to informed consent in the context of uncertainty and virtual consent. Finally, the third category describes ethical issues related to organ allocation, such as social considerations in selecting transplant candidates.ConclusionThis literature review highlights the salient ethical issues related to OTDT during the current COVID-19 pandemic. As medical and scientific knowledge about COVID-19 increases, the uncertainties related to this disease will decrease and the associated ethical issues will continue to evolve. (shrink)

Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

Faculty lessons learned are also described, facilitating adoption of (...) this methotrexate ethics case by other healthcare profession educators. (shrink)

Genomic research projects that collect tissues from deceased organ and tissue donors must obtain the authorization of family decision makers under difficult circumstances that may affect the authorization process. Using a quasi-experimental design, the Ethical, Legal, and Social Issues (ELSI) substudy of the Genotype-Tissue Expression (GTEx) project compared the recall and understanding of the donation authorization process of two groups: family members who had authorized donation of tissues to the GTEx project (the comparison group) and family members who had authorized (...) organ and tissue donations in years previous, who subsequently participated in two different mock-authorization processes that mimicked the GTEx authorization process (the intervention groups). Participants in the comparison and intervention groups were matched on key demographic characteristics.We found that participants in the intervention groups who experienced a mock-authorization process demonstrated better recall of the tissue donation request than members of the comparison group. Our data indicate that the stress associated with the loss of a loved one limited the ability of family members to recall details about the GTEx project. However, we found a similar lack of knowledge in both the comparison and the intervention group participants, suggesting lack of knowledge may be due to the complexity and unfamiliarity of the information presented to them during the authorization process. We discuss these findings in the context of everyday clinical decision making in cognitively challenging conditions. (shrink)

Physical activity and sedentary behaviour have been linked to the mental health of children and adolescents, yet the timing of behaviours may play a role in this relationship and clarifying this could inform interventions. We explored cross-sectional associations of PA and SED in varying time segments throughout the school day with the mental health of school-aged children and adolescents from rural Northeastern Ontario, Canada. A total of 161 students wore accelerometers for 8 days and completed a self-report survey. Mental health (...) was measured using the Strengths and Difficulties Questionnaire. Accelerometer-measured SED, light PA, and moderate and vigorous PA were estimated in the time-segments before school, school time, after school, and evenings. Associations were tested with multilevel linear regressions while adjusting for confounding factors. Students spent 72.6 min in MVPA, 209.0 min in LPA, and 621.0 min in SED per day. Daily SED was associated with less conduct problems. Evening LPA was inversely associated with hyperactivity, while SED was associated with hyperactivity and with peer problems before school, and during school. No associations were observed for MVPA, emotional symptoms, or prosocial behaviour. In conclusion, displacing SED with LPA in some specific periods of the day may benefit the mental health of students; taking this into account could strengthen interventions. (shrink)

One of the most important aspects of Grice’s theory of conversation is the drawing of a borderline between what is said and what is implic- ated. Grice’s views concerning this borderline have been strongly and influentially criticised by relevance theorists. In particular, it has become increasingly widely accepted that Grice’s notion of what is said is too lim- ited, and that pragmatics has a far larger role to play in determining what is said than Grice would have allowed. (See for (...) example Bezuidenhuit 1996; Blakemore 1987; Carston 1991; Recanati 1991, 1993, 2001; Sperber and Wilson 1986; Wilson and Sperber 1981.) In this paper, I argue that the rejection of Grice has moved too swiftly, as a key line of objection which has led to this rejection is flawed. The flaw, we will see, is that relevance theorists rely on a misunderstanding of Grice’s project in his theory of conversation. I am not arguing that Grice’s versions of saying and implicating are right in all details, but simply that certain widespread reasons for rejecting his theory are based on misconceptions. (shrink)

Newborn bloodspot screening programs are some of the longest running population screening programs internationally. Debate continues regarding the need for parents to give consent to having their child screened. Little attention has been paid to how meanings of consent-related terminology vary among stakeholders and the implications of this for practice. We undertook semi-structured interviews with parents, healthcare professionals and policy decision makers in two Canadian provinces. Conceptions of consent-related terms revolved around seven factors within two broad domains, decision-making and information (...) attainment. Decision-making comprised: parent decision authority; voluntariness; parent engagement with decision-making; and the process of enacting choice. Information ascertainment comprised: professional responsibilities ; parent responsibilities; and the need for discussion and understanding prior to a decision. Our findings indicate that consent-related terms are variously understood, with substantive implications for practice. We suggest that consent procedures should be explained descriptively, regardless of approach, so there are clear indications of what is expected of parents and healthcare professionals. Support systems are required both to meet the educational needs of parents and families and to support healthcare professionals in delivering information in a manner in keeping with parent needs.

© Copyright 2015, Mary Ann Liebert, Inc..Signal transducer and activator of transcription factor 3 is hyperactivated in head and neck squamous cell carcinomas. Cumulative evidence indicates that IL-6 production by HNSCC cells and/or stromal cells in the tumor microenvironment activates STAT3 and contributes to tumor progression and drug resistance. A library of 94,491 compounds from the Molecular Library Screening Center Network was screened for the ability to inhibit interleukin-6 -induced pSTAT3 activation. For contractual reasons, the primary high-content screening campaign was (...) conducted over several months in 3 distinct phases; 1,068 primary HCS actives remained after cytotoxic or fluorescent outliers were eliminated. One thousand one hundred eighty-seven compounds were cherry-picked for confirmation; actives identified in the primary HCS and compounds selected by a structural similarity search of the remaining MLSCN library using hits identified in phases I and II of the screen. Actives were confirmed in pSTAT3 IC50 assays, and an IFNγ-induced pSTAT1 activation assay was used to prioritize selective inhibitors of STAT3 activation that would not inhibit STAT1 tumor suppressor functions. Two hundred three concentration-dependent inhibitors of IL-6-induced pSTAT3 activation were identified and 89 of these also produced IC50s against IFN-γ-induced pSTAT1 activation. Forty-nine compounds met our hit criteria: they reproducibly inhibited IL-6-induced pSTAT3 activation by ≥70% at 20 μM; their pSTAT3 activation IC50s were ≤25 μM; they were ≥2-fold selective for pSTAT3 inhibition over pSTAT1 inhibition; a cross target query of PubChem indicated that they were not biologically promiscuous; and they were ≥90% pure. Twenty-six chemically tractable hits that passed filters for nuisance compounds and had acceptable drug-like and ADME-Tox properties by computational evaluation were purchased for characterization. The hit structures were distributed among 5 clusters and 8 singletons. Twenty-four compounds inhibited IL-6-induced pSTAT3 activation with IC50s ≤20 μM and 13 were ≥3-fold selective versus inhibition of pSTAT1 activation. Eighteen hits inhibited the growth of HNSCC cell lines with average IC50s ≤ 20 μM. Four chemical series were progressed into lead optimization: the guanidinoquinazolines, the triazolothiadiazines, the amino alcohols, and an oxazole-piperazine singleton. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:7 Forum: Teaching about Ferguson 8 Feminist Studies 41, no. 1. © 2015 by Feminist Studies, Inc. 211 Jennifer C. Nash Teaching about Ferguson: An Introduction This forum was organized around the idea of asking feminist scholars to reflect on the practice of teaching about racial violence as well as on the experiences of teaching in the midst of racial violence. What do feminist pedagogies centered on Ferguson (...) and its aftermath look like? How do we present the various forms of violence—including state action (in the case of murder) and state inaction (in the case of nonindictments)— that produce and uphold the conditions that mark the current situation? How do we bring our feelings about this moment into our classrooms, and how do we do this feeling-teaching in ways that attend to the fact that feminist scholars are endlessly called on to perform affective labor and also that racialized and gendered bodies’ affects are policed inside and outside of the academy? What happens if we refuse the composure that faculty bodies are supposed to perform and enact grief, rage, or sadness? What happens if we refuse performing anything but exhaustion, numbness, or a protective desire to shield our bodies from our students’ scrutiny or curiosity? It quickly became apparent that a forum focused on “feminist pedagogies of Ferguson” would be far more expansive than a conversation focused on how to teach about Ferguson; put simply, to speak about Ferguson is always to speak about more than Ferguson. “Ferguson” has become shorthand for a murdered young man, Michael Brown, for a grand jury’s nonindictment of the police officer who shot him, and for 212 Jennifer C. Nash the Department of Justice’s recommendation not to bring civil rights charges against the officer, Darren Wilson. “Ferguson” has also become shorthand for a number of lives that ended violently, often at the hands of the state: Eric Garner, Oscar Grant, Trayvon Martin, Tarika Wilson, Tanisha Anderson, Renisha McBride, and Tamir Rice, to name a few. “Ferguson,” then, has become a keyword around which scholars organize conversations about legal murders, the variety of laws that regard property more than black life (so-called stand-your-ground laws, for example), racial profiling, stop and frisk, mass imprisonment, the death penalty, and the racial logics of systems of value that ensure that racially marked bodies are, in Lisa Marie Cacho’s words, “ineligible for personhood.”1 The scholars included in this forum capture the expansive ways that we, as scholars and educators, articulate the meanings of this moment and the ways that we situate Brown’s death in the conditions of the unfolding present. The scholars included in this forum also powerfully ask about the possibilities for activism in the wake of Ferguson(s) and the powerful coalitions that have formed in the wake of Ferguson(s). If “Black Lives Matter” (and #blacklivesmatter) and “I Can’t Breathe” have become refrains that respond to the violence of the present by making visible black pain, the scholars included here voice the possibilities these movements might open up. We can consider these possibilities alongside the painful truth that it takes spectacular violence to generate a widespread articulation of black bodies as bodies that matter. 1.

Abstract:AbstractProfessor James opens her essay “Looking” with her aging mother's distressed response to the televised images of Ferguson on the evening District Attorney McCulloch announced that Darren Wilson would not be indicted for killing Michael Brown. A St. Louis native, she had left the city as a young woman to flee the twinned violence of sexism and racism and had never resided there again. James juxtaposes her mother's attempt to “not look back” at the circumstances she left behind against (...) the intentional, political and historical practice of “black feminist looking.” Drawing energy from bell hooks' early theories of the black “oppositional gaze,” James argues that turning to Ida B. Wells' unflinching portrayals of lynching in the classroom can demonstrate black feminist looking's transformative power. She suggests this looking represents a potentially empowering confrontation with black melancholic grief, and that black grief can only be pedagogical if unleashed, acknowledged and historicized.

This article discusses Jennifer Hornsby's account of action in her *Actions*, together with Brian O'Shaughnessy's in *The Will*.

Dispositions can combine as vector sums. Recent authors on dispositions, such as George Molnar and Stephen Mumford, have responded to this feature of dispositions by introducing a distinction between effects and contributions to effects, and by identifying disposition-manifestations with the latter. But some have been sceptical of the reality or knowability of component vectors; Jennifer McKitrick (forthcoming) presses these concerns against the conception of manifestations as contributions to effects. In this paper, I aim to respond to McKitrick's arguments and (...) to defend the metaphysical and epistemological propriety of component vectors. My strategy appeals to varying kinematic frames of reference. By transforming to the appropriate non-inertial frame, component acceleration vectors can be transformed into resultant acceleration vectors, and in such frames they become directly observable. Being a component acceleration vector and being a resultant acceleration vector are both frame-dependent properties of properties; they are not to be thought of as intrinsic or fundamental properties of an acceleration vector, but as artefacts of our frame-dependent notation for representing vector quantities. To conclude the paper, I defend the view proposed against two styles of objection. The first objection resurrects scepticism about component vectors as scepticism about fundamental component vectors. The second objection questions the need for reference frames in the explanation by invoking a 'counterfactual' theory of contributions. (shrink)

Testimony is an invaluable source of knowledge. We rely on the reports of those around us for everything from the ingredients in our food and medicine to the identity of our family members. Recent years have seen an explosion of interest in the epistemology of testimony. Despite the multitude of views offered, a single thesis is nearly universally accepted: testimonial knowledge is acquired through the process of transmission from speaker to hearer. In this book, Jennifer Lackey shows that this (...) thesis is false and, hence, that the literature on testimony has been shaped at its core by a view that is fundamentally misguided. She then defends a detailed alternative to this conception of testimony: whereas the views currently dominant focus on the epistemic status of what speakers believe, Lackey advances a theory that instead centers on what speakers say. The upshot is that, strictly speaking, we do not learn from one another's beliefs - we learn from one another's words. Once this shift in focus is in place, Lackey goes on to argue that, though positive reasons are necessary for testimonial knowledge, testimony itself is an irreducible epistemic source. This leads to the development of a theory that gives proper credence to testimony's epistemologically dual nature: both the speaker and the hearer must make a positive epistemic contribution to testimonial knowledge. The resulting view not only reveals that testimony has the capacity to generate knowledge, but it also gives appropriate weight to our nature as both socially indebted and individually rational creatures. The approach found in this book will, then, represent a radical departure from the views currently dominating the epistemology of testimony, and thus is intended to reshape our understanding of the deep and ubiquitous reliance we have on the testimony of those around us.

This is not your psychoanalyst's unconscious.

When people speak, their words never fully encode what they mean, and the context is always compatible with a variety of interpretations. How can comprehension ever be achieved? Wilson and Sperber argue that comprehension is an inference process guided by precise expectations of relevance. What are the relations between the linguistically encoded meanings studied in semantics and the thoughts that humans are capable of entertaining and conveying? How should we analyse literal meaning, approximations, metaphors and ironies? Is the ability (...) to understand speakers' meanings rooted in a more general human ability to understand other minds? How do these abilities interact in evolution and in cognitive development? MEANING AND RELEVANCE sets out to answer these and other questions, enriching and updating relevance theory and exploring its implications for linguistics, philosophy, cognitive science and literary studies.

A widely accepted view in recent work in epistemology is that knowledge is a cognitive achievement that is properly creditable to those subjects who possess it. More precisely, according to the Credit View of Knowledge, if S knows that p, then S deserves credit for truly believing that p. In spite of its intuitive appeal and explanatory power, I have elsewhere argued that the Credit View is false. Various responses have been offered to my argument and I here consider each (...) of these objections in turn. I show that none succeeds in undermining my argument and, thus, my original conclusion stands—the Credit View of Knowledge is false. (shrink)
