Livestock production in both industrial systems, where livestock are packed tightly together, and in highly traditional systems, where a shepherd follows her herd in dispersed rangelands, are cited as key contributors in some of the most acute environmental problems around the globe. Israel is one of the few countries where both of these systems exist, with surprisingly little contact between them. The environmental impact of the sectors were examined along with Israel’s public policies in the field. While historically, much attention (...) has been placed on the contribution of the Bedouin pastoralists to desertification and erosion, this may be linked to historic misapprehension about actual impacts of goats on local rangelands as well as political motivations and concerns about losing national sovereignty over large areas of rangelands. The true environmental effects appear to be minor. A far more critical concern is water pollution caused by the industrial sector of livestock production—an issue that recently has attracted considerable government attention and investment in a successful dairy infrastructure initiative. The divisions between governmental supports for the Jewish and Arab sectors of livestock management are inconsistent with efficient environmental management. Policies should be designed to encourage Bedouin to find ways to sustainably continue their traditional livestock husbandry practises, which today are largely associated with ecological benefits and constitute a unique cultural asset for Israel and the world.

ABSTRACTShould conciliating with disagreeing peers be considered sufficient for reaching rational beliefs? Thomas Kelly argues that when taken this way, Conciliationism lets those who enter into a disagreement with an irrational belief reach a rational belief all too easily. Three kinds of responses defending Conciliationism are found in the literature. One response has it that conciliation is required only of agents who have a rational belief as they enter into a disagreement. This response yields a requirement that no one should (...) follow. If the need to conciliate applies only to already rational agents, then an agent must conciliate only when her peer is the one irrational. A second response views conciliation as merely necessary for having a rational belief. This alone does little to address the central question of what is rational to believe when facing a disagreeing peer. Attempts to develop the response either reduce to the first response, or deem necessary an unnecessary doxastic revision, or imply that rational dilemmas obtain in cases where intuitively there are none. A third response tells us to weigh what our pre-disagreement evidence supports against the evidence from the disagreement itself. This invites epistemic akrasia. (shrink)

Epistemically akratic agents believe both p and that believing p is irrational for them. Some of the costs of thinking that epistemic akrasia can be rational are clear. It is hypocritical, and outright weird, to have beliefs that we consider irrational, let alone to reason with or act on those beliefs. However, as Maria Lasonen-Aarnio (2020) and Brian Weatherson (2019) have argued, the weirdness of akrasia does not obviously tell against its rationality. Here I argue that views permitting epistemic akrasia (...) fare worse than previously thought. These views imply that we should sometimes have beliefs that we know for certain are either irrational or false. And while having a belief that we know to be irrational is straightforwardly irrational, the additional possibility that the belief may be false cannot make having it any more rational. (shrink)

In this book, Tal Ben-Shahar introduces a new interdisciplinary field of study that is dedicated to exploring happiness. The study of happiness ought not be left to psychologists alone. Philosophers, theologians, biologists, economists, and scholars from other disciplines have explored ways of attaining happiness, and to do justice to this important pursuit, we ought to listen to their words and experiment with their prescriptions. Not only does the field of happiness studies embrace different disciplines, it also approaches happiness as a (...) multifaceted and multidimensional variable that includes five parts which form the acronym SPIRE: Spiritual wellbeing Physical wellbeing Intellectual wellbeing Relational wellbeing Emotional wellbeing This book addresses each of these elements of happiness, explains them, and addresses practical ways for their cultivation.

A growing body of literature focuses on practice as a central aspect of teacher education. Whereas this approach emerged mainly from teacher preparation programs in specific content areas such as math, science, and literacy studies, socially related educational fields have served as a peripheral player alone. Recently, however, scholars have suggested incorporating a practice-based approach to teacher education into the social studies. In this article, we draw on complexity theory to reexamine this proposal, evaluating the connections between teaching practices and (...) democratic citizenship. First, we introduce complexity theory. Second, we offer a critical examination of key publications discussing practice-based teacher education, using the components of complexity theory as an organizing scheme. We then highlight practice-based teacher education’s reductive aspects, leading to an argument that promoting democratic citizenship through civics teacher education should be seen as a complex endeavor where borders are blurred, interactions are nonlinear, and reality changes frequently. Finally, we offer to supplement the practice approach with aspects of teacher education that stem from complexity theory. (shrink)

In the late 1930's Blondel precipitated a debate over the question of a Christian philosophy in a series of articles on St. Augustine insisting on the philosophical nature of the saint's thought. Rationalist historian of philosophy Bréhier objected to the very idea of a Christian philosophy. Other historians like Gilson allowed that a philosophy could be characterized loosely as Christian when it was associated with Christian thought, as in the Middle Ages. But Blondel argued against both of these positions as (...) presupposing a separation between philosophy and religion that allowed only for a false hybridization between the two when they were juxtaposed. His own approach to philosophy had been to show a necessary intersection between the two in the question about the ultimate meaning of human action as it relates to God in his infinite transcendence, as this had long been understood in the Catholic tradition, that is, as relating to something supernatural in the strictest sense, something bound to appear as scandalous and paradoxical to reason alone. The present article examines how he first came to his philosophical method for dealing with this question in the 1890's and how he later used this method in defending the idea of a philosophy that was integrally rational and Catholic in the strict sense of both terms. /// Na década de 1930, Maurice Blondel desencadeou um importante debate acerca da questão da chamada Filosofia Cristã mediante uma série de artigos sobre Santo Agostinho, os quais insistiam em particular sobre a natureza filosófica do pensamento do grande santo. Bréhier, um historiador da Filosofia de tendência racionalista, objectou à própria ideia de uma Filosofia Cristã. Outros historiadores, tais como E. Gilson, concediam que uma Filosofia poderia ser vagamente caracterizada como Cristã quando a mesma esteja associada com o pensamento cristão, como era o caso na Idade Média. Mas Blondel argumentava contra estas duas posições na medida em que achava que as mesmas pressuponham a separação entre Filosofia e Religião, separação esta que permitia apenas uma falsa hibridização entre as duas quando as mesmas eram justapostas. A sua posição pessoal em relação à Filosofia defendia que entre esta e a Religião existia uma intersecçdo necessária acerca da questão relativa ao sentido ultimo da acçdo humana na medida em que esta remete para Deus na sua infinita transcendência, tal como esta era desde há muito compreendida na tradição Católica, ou seja, enquanto que remetendo para algo sobrenatural no sentido mais estrito, algo destinado a aparecer como escandaloso e paradoxal à razão enquanto que entregue a si mesma. O presente artigo examina de que modo Blondel primeiro chegou ao seu método filosófico no tratamento desta questão na década de 1890 e de como ele mais tarde usou este método para defender a ideia de uma Filosofia que é integralmente racional e católica no sentido mais estrito de ambos os termos.

This paper draws attention to an increasingly common method of using computer simulations to establish evidential standards in physics. By simulating an actual detection procedure on a computer, physicists produce patterns of data (‘signatures’) that are expected to be observed if a sought-after phenomenon is present. Claims to detect the phenomenon are evaluated by comparing such simulated signatures with actual data. Here I provide a justification for this practice by showing how computer simulations establish the reliability of detection procedures. I (...) argue that this use of computer simulation undermines two fundamental tenets of the Bogen–Woodward account of evidential reasoning. Contrary to Bogen and Woodward’s view, computer-simulated signatures rely on ‘downward’ inferences from phenomena to data. Furthermore, these simulations establish the reliability of experimental setups without physically interacting with the apparatus. I illustrate my claims with a study of the recent detection of the superfluid-to-Mott-insulator phase transition in ultracold atomic gases. (shrink)

This new work offers radical new study of Levinas and Camus, two leading thinkers of the 20th century.

Most theories and hypotheses in psychology are verbal in nature, yet their evaluation overwhelmingly relies on inferential statistical procedures. The validity of the move from qualitative to quantitative analysis depends on the verbal and statistical expressions of a hypothesis being closely aligned – that is, that the two must refer to roughly the same set of hypothetical observations. Here, I argue that many applications of statistical inference in psychology fail to meet this basic condition. Focusing on the most widely used (...) class of model in psychology – the linear mixed model – I explore the consequences of failing to statistically operationalize verbal hypotheses in a way that respects researchers' actual generalization intentions. I demonstrate that although the “random effect” formalism is used pervasively in psychology to model intersubject variability, few researchers accord the same treatment to other variables they clearly intend to generalize over. The under-specification of random effects imposes far stronger constraints on the generalizability of results than most researchers appreciate. Ignoring these constraints can dramatically inflate false-positive rates, and often leads researchers to draw sweeping verbal generalizations that lack a meaningful connection to the statistical quantities they are putatively based on. I argue that failure to take the alignment between verbal and statistical expressions seriously lies at the heart of many of psychology's ongoing problems, and conclude with a discussion of several potential avenues for improvement.

This work develops an epistemology of measurement, that is, an account of the conditions under which measurement and standardization methods produce knowledge as well as the nature, scope, and limits of this knowledge. I focus on three questions: (i) how is it possible to tell whether an instrument measures the quantity it is intended to? (ii) what do claims to measurement accuracy amount to, and how might such claims be justified? (iii) when is disagreement among instruments a sign of error, (...) and when does it imply that instruments measure different quantities? Based on a series of case studies conducted in collaboration with the US National Institute of Standards and Technology (NIST), I argue for a model-based approach to the epistemology of physical measurement. To measure a physical quantity, I argue, is to estimate the value of a parameter in an idealized model of a physical process. Such estimation involves inference from the final state (‘indication’) of a process to the value range of a parameter (‘outcome’) in light of theoretical and statistical assumptions. Contrary to contemporary philosophical views, measurement outcomes cannot be obtained by mapping the structure of indications. Instead, measurement outcomes as well as claims to accuracy, error and quantity individuation can only be adjudicated relative to a choice of idealized modelling assumptions. (shrink)

We are currently witnessing a sharp rise in the use of algorithmic decision-making tools. In these instances, a new wave of policy concerns is set forth. This article strives to map out these issues, separating the wheat from the chaff. It aims to provide policy makers and scholars with a comprehensive framework for approaching these thorny issues in their various capacities. To achieve this objective, this article focuses its attention on a general analytical framework, which will be applied to a (...) specific subset of the overall discussion. The analytical framework will reduce the discussion to two dimensions, every one of which addressing two central elements. These four factors call for a distinct discussion, which is at times absent in the existing literature. The two dimensions are the specific and novel problems the process assumedly generates and the specific attributes which exacerbate them. While the problems are articulated in a variety of ways, they most likely could be reduced to two broad categories: efficiency and fairness-based concerns. In the context of this discussion, such problems are usually linked to two salient attributes the algorithmic processes feature—its opaque and automated nature. (shrink)

The digital age brings with it novel forms of data flow. As a result, individuals are constantly being monitored while consuming products, services and content. These abilities have given rise to a variety of concerns, which are most often framed using “privacy” and “data protection”-related paradigms. An important, oft-noted yet undertheorized concern is that these dynamics might facilitate the manipulation of subjects; a process in which firms strive to motivate and influence individuals to take specific steps and make particular decisions (...) in a manner considered to be socially unacceptable. That it is important and imperative to battle manipulation carries with it a strong intuitive appeal. Intuition, however, does not always indicate the existence of a sound justification or policy option. For that, a deeper analytic and academic discussion is called for. This Article begins by emphasizing the importance of addressing the manipulation-based argument, which derives from several crucial problems and flaws in the legal and policy setting currently striving to meet the challenges of the digital age. Next, the Article examines whether the manipulation-based concerns are sustainable, or are merely a visceral response to changing technologies which cannot be provided with substantial analytical backing. Here the Article details the reasons for striving to block manipulative conduct and, on the other hand, reasons why legal intervention should be, in the best case, limited. The Article concludes with some general implications of this discussion for the broader themes and future directions of privacy law, while trying to ascertain whether the rise of the manipulation-based discourse will lead to information privacy’s expansion or perhaps its demise.

Contrary to the claim that measurement standards are absolutely accurate by definition, I argue that unit definitions do not completely fix the referents of unit terms. Instead, idealized models play a crucial semantic role in coordinating the theoretical definition of a unit with its multiple concrete realizations. The accuracy of realizations is evaluated by comparing them to each other in light of their respective models. The epistemic credentials of this method are examined and illustrated through an analysis of the contemporary (...) standardization of time. I distinguish among five senses of ‘measurement accuracy’ and clarify how idealizations enable the assessment of accuracy in each sense. (shrink)

This article explores the relation between belief-like imaginings and the establishment of imaginary worlds (often called fictional worlds). After outlining the various assumptions my argument is premised on, I argue that belief-like imaginings, in themselves, do not render their content true in the imaginary world to which they pertain. I show that this claim applies not only to imaginative projects in which we are instructed or intend to imagine certain propositions, but also to spontaneous imaginative projects. After arguing that, like (...) guided imaginative projects, spontaneous projects involve specific imaginary truths, I conclude that imaginative projects, whether spontaneous or deliberate, comprise not only imaginings, but also mental acts of determining such truths.

When discrepancies are discovered between the outcomes of different measurement procedures, two sorts of explanation are open to scientists. Either some of the outcomes are inaccurate or the procedures are not measuring the same quantity. I argue that, due to the possibility of systematic error, the choice between and is underdetermined in principle by any possible evidence. Consequently, foundationalist criteria of quantity individuation are either empty or circular. I propose a coherentist, model-based account of measurement that avoids the underdetermination problem, (...) and use this account to explain how scientists individuate quantities in practice.

Criminal sanctions are typically inflicted by the state. The central role of the state in determining the severity of these sanctions and inflicting them requires justification. One justification for state-inflicted sanctions is simply that the state is more likely than other agents to determine accurately what a wrongdoer justly deserves and to inflict a just sanction on those who deserve it. Hence, in principle, the state could be replaced by other agents, for example, private individuals. This hypothesis has given rise (...) to recent calls to reform the state's criminal justice system by introducing privately inflicted sanctions, for example, shaming penalties, private prisons, or private probationary services. This paper challenges this view and argues that the agency of the state is indispensable to criminal sanctions. Privately inflicted sanctions sever the link between the state's judgments concerning the wrongfulness of the action and the appropriateness of the sanction and the infliction of sufferings on the criminal. When a private individual inflicts punishment, she acts on what she and not the state judges to be a justified response to a criminal act. Privately inflicted sanctions for violations of criminal laws are not grounded in the judgments of the appropriate agent, namely the state. It is impermissible on the part of the state to approve, encourage, or initiate the infliction of a sanction on an alleged wrongdoer on the basis of a private judgment. Such an approval grants undue weight to the private judgment of the individual who inflicts the sanction. (shrink)

Curiosity and creativity are central pillars of human growth and invention. Although they have been studied extensively in isolation, the relationship between them has not yet been established. We propose that both curiosity and creativity emanate from the same mechanism of novelty seeking. We first present a synthesis showing that curiosity and creativity are affected similarly by a number of key cognitive faculties such as memory, cognitive control, attention, and reward. We then review empirical evidence from neuroscience research, indicating that (...) the same brain regions are involved in both curiosity and creativity, focusing on the interplay between three major brain networks: the default mode network, the salience network, and the executive control network. After substantiating the link between curiosity and creativity, we propose a novelty-seeking model (NSM) that underlies them and suggests that the manifestation of the NSM is governed by one's state of mind.

We examine whether the "evidence of evidence is evidence" principle is true. We distinguish several different versions of the principle and evaluate recent attacks on some of those versions. We argue that, whatever the merits of those attacks, they leave the more important rendition of the principle untouched. That version is, however, also subject to new kinds of counterexamples. We end by suggesting how to formulate a better version of the principle that takes into account those new counterexamples.

In this book, Tal S. Shamir sets out to identify cinema as a novel medium for philosophy and an important way of manifesting and developing philosophical thought. The volume presents a comprehensive analysis of the nature of philosophy's potential-or, more strongly put, its need-to be manifested cinematically. Drawing on the fields of cinema, philosophy, and media studies, Cinematic Philosophy adds film to the traditional list of ways through which philosophy can be created, concentrating on the unique potential of the cinematic (...) medium to effectively put forward and create philosophy. In the process, the book opens up innovative horizons for new types of knowledge and wisdom grounded in contemporary contexts and philosophical thought. Philosophy, best characterized as the love of wisdom, is not dependent on a specific medium nor solely situated within written text or oral lectures. Shamir asserts that philosophy can, should, and must be manifested and identified in a range of different platforms. (shrink)

The philosophy of measurement studies the conceptual, ontological, epistemic, and technological conditions that make measurement possible and reliable. A new wave of philosophical scholarship has emerged in the last decade that emphasizes the material and historical dimensions of measurement and the relationships between measurement and theoretical modeling. This essay surveys these developments and contrasts them with earlier work on the semantics of quantity terms and the representational character of measurement. The conclusions highlight four characteristics of the emerging research program in (...) philosophy of measurement: it is epistemological, coherentist, practice oriented, and model based. (shrink)

Since the 1960s, the influence of economic thought on education has been steadily increasing. Taking Jean-Jacques Rousseau's educational thought as a point of departure, Tal Gilead critically inquires into the philosophical foundations of what can be termed the economic approach to education. Gilead's focus in this essay is on happiness and the role that education should play in promoting it. The first two parts of the essay provide an introduction to Rousseau's conception of happiness, followed by an examination of the (...) economic approach to education and the notion of human capital. In the course of this discussion, Gilead shows that increasing happiness is one of the economic approach's major aims. In the third part of the essay, he uses Rousseau's views to interrogate significant aspects of the economic approach to education. He then continues by highlighting some of the educational implications that stem from Rousseau's critique. Gilead maintains that Rousseau's ideas can provide valuable suggestions regarding how education might contribute to the promotion of happiness. The article concludes by proposing that while Rousseau's ideas on the matter should not necessarily be embraced, contemporary policymakers can learn some important lessons from them. (shrink)

A recent paper suggested that if Galilean covariance was extended to signals and interactions, the resulting theory would contain such anomalies as would have impelled physicists towards special relativity even without empirical prompts. I analyze this claim. Some so-called anomalies turn out to be errors. Others have classical analogs, which suggests that classical physicists would not have viewed them as anomalous. Still others, finally, remain intact in special relativity, so that they serve as no impetus towards this theory. I conclude (...) that Galilean covariance is insufficient to derive special relativity. (shrink)

This article develops a model-based account of the standardization of physical measurement, taking the contemporary standardization of time as its central case-study. To standardize the measurement of a quantity, I argue, is to legislate the mode of application of a quantity-concept to a collection of exemplary artefacts. Legislation involves an iterative exchange between top-down adjustments to theoretical and statistical models regulating the application of a concept, and bottom-up adjustments to material artefacts in light of remaining gaps. The model-based account clarifies (...) the cognitive role of ad hoc corrections, arbitrary rules and seemingly circular inferences involved in contemporary timekeeping, and explains the stability of networks of standards better than its conventionalist and constructivist counterparts.

Over the last few decades, the idea that education should function to promote economic progress has played a major role in shaping educational policy. So far, however, philosophers of education have shown relatively little interest in analysing this notion and its implications. The present article critically examines, from a philosophical perspective, the link between education and the currently prevailing understanding of economic progress, which is grounded in human capital theory. A number of familiar philosophical objections to the idea that economic (...) progress is a worthy educational aim are raised, but it is held that many of these objections stem from a partial understanding of economic theory. The article then moves on to investigate the foundations of human capital theory's conception of economic progress. It is argued that there are inherent tensions between the philosophical foundations of the economist's conception of progress and the very essence of education. The article concludes by suggesting that in order to resolve these tensions we should consider grounding the economic theory that guides educational policy-making in an intersubjective or objective conception of welfare.

The presence of gene–environment statistical interaction and correlation in biological development has led both practitioners and philosophers of science to question the legitimacy of heritability estimates. The paper offers a novel approach to assess the impact of GxE and rGE on the way genetic and environmental causation can be partitioned. A probabilistic framework is developed, based on a quantitative genetic model that incorporates GxE and rGE, offering a rigorous way of interpreting heritability estimates. Specifically, given an estimate of heritability and (...) the variance components associated with estimates of GxE and rGE, I arrive at a probabilistic account of the relative effect of genes and environment.

Suppose we learn that we have a poor track record in forming beliefs rationally, or that a brilliant colleague thinks that we believe P irrationally. Does such input require us to revise those beliefs whose rationality is in question? When we gain information suggesting that our beliefs are irrational, we are in one of two general cases. In the first case we made no error, and our beliefs are rational. In that case the input to the contrary is misleading. In (...) the second case we indeed believe irrationally, and our original evidence already requires us to fix our mistake. In that case the input to that effect is normatively superfluous. Thus, we know that information suggesting that our beliefs are irrational is either misleading or superfluous. This, I submit, renders the input incapable of justifying belief revision, despite our not knowing which of the two kinds it is. (shrink)

Le texte publié par Kant en 1791, ayant comme thème l’insuccès de toutes les tentatives en matière de théodicée, suscite en général peu d’intérêt. Cet article cherche à montrer que ce texte en particulier et le problème de la théodicée en général, gardent tout leur intérêt au sein de la philosophie kantienne, malgré la révolution copernicienne et peut-être en raison d’elle. Nous voudrions montrer que ce texte permet de lier la philosophie théorique — le criticisme — et la philosophie pratique, (...) et cela, autour de l’idée du mensonge, paradigme de ce qui deviendra, dans la philosophie kantienne de la religion, le mal radical. Il est alors aisé de constater que cette dernière, contrairement à une lecture tenace qui en fait une partie marginale au sein du kantisme, est indispensable pour donner du sens au projet kantien, et que la théodicée, sous sa forme authentique, réhabilitée, constitue une pièce maîtresse de cet édifice. Kant’s short text about the failure of all attempted philosophical theodicies is generally considered as a minor text. Our paper tries to show that the problem of theodicy, despite the Copernican Revolution and the condemnation of philosophical dogmatism it involves, and maybe because of this condemnation, remains a main interest in Kant, an interest which explains why this the 1791’s text should be carefully read, in order to understand the place that the new and authentic theodicy plays in Kant’s practical philosophy. Through this text, one can see the original way in which Kant manages to use the insincere character of Job’s friends in order to show how the epistemological error denounced by the first Critique becomes a moral failure, an idea which prepares the famous notion of radical evil, a central notion in Kant’s philosophy of religion. Theodicy in particular, philosophy of religion in general, can, under these considerations, be seen as important pieces in Kant’s philosophy, as important weapons against this deep pessimism, involved by the radical evil in human nature.

Panmicropsychism is the view that the fundamental physical ingredients of our universe are also its fundamental phenomenal ingredients. Since there is only a limited number of fundamental physical ingredients, panmicropsychism seems to imply that there exists only a small set (palette) of basic phenomenal qualities. How does this limited palette of basic phenomenal qualities give rise to our rich set of experiences? This is known as ‘the palette problem’. One class of solutions to this problem, large-palette solutions, simply denies that (...) the palette is limited. These solutions assume that all types of phenomenal qualities (color, sound, odor, taste, etc., and presumably also types not experienced by humans) were created fully formed at the birth of our universe. On this view, brains evoke conscious experiences by sampling primordial, preexisting phenomenal spaces. My main claim in this paper is that, by analogy with the mathematical description of the fundamental physical ingredients of our universe, which exhibits simplicity, symmetry, and beauty, panmicropsychists should expect the mathematical description of the fundamental phenomenal ingredients of our universe to exhibit similar features. The goal of this paper is to exemplify this claim using what is arguably the simplest of all types of phenomenal qualities—color. Specifically, I utilize phenomenological data on color to construct the maximally symmetric mathematical description of phenomenal color space. I then show that this mathematical description is isomorphic to the mathematical description of two-state quantum systems in a mixed state. Based on this isomorphism, I suggest that color may be the phenomenal dual aspect of two-state quantum systems. (shrink)

Hering’s opponent-colors theory suggests that our color sensations are produced by three mechanisms: a red–green mechanism, a yellow–blue mechanism, and a white–black mechanism. The first two mechanisms give rise to our sensations of hued colors; the third mechanism gives rise to our sensations of hueless colors. Noticeably, whereas the pair of colors produced by each of the hued mechanisms do not mix to yield a phenomenal intermediate (i.e., there are no greenish reds, reddish greens, yellowish blues, or bluish yellows), the (...) colors produced by the hueless mechanism, white and black, do have a phenomenal intermediate—gray. This different behavior of the white–black mechanism poses a problem for Hering’s theory. Several attempts to fix this problem have been suggested. This paper focuses on the suggestion made by Paul Heggelund a century after Hering proposed his theory. In Heggelund’s amendment of Hering’s theory, the hueless colors are not confined to the one-dimensional gamut between black and white, but rather require two components for their full description: a light–dark (or luminous–black) component, where light and dark are mutually exclusive sensations, and a white component, which doesn’t have an opponent counterpart. Here I show that although Heggelund’s theory indeed provides a solution to the problem that the hueless colors pose to Hering’s theory, it is not self-consistent. I go on to revise Heggelund’s theory to obtain a consistent opponent-colors theory. (shrink)

Euthanasia and physician assisted-suicide are terms used to describe the process in which a doctor of a sick or disabled individual engages in an activity which directly or indirectly leads to their death. This behavior is engaged by the healthcare provider based on their humanistic desire to end suffering and pain. The psychiatrist's involvement may be requested in several distinct situations including evaluation of patient capacity when an appeal for euthanasia is requested on grounds of terminal somatic illness or when (...) the patient is requesting euthanasia due to mental suffering. We compare attitudes of 49 psychiatrists towards euthanasia and assisted suicide with a group of 54 other physicians by means of a questionnaire describing different patients, who either requested physician-assisted suicide or in whom euthanasia as a treatment option was considered, followed by a set of questions relating to euthanasia implementation. When controlled for religious practice, psychiatrists expressed more conservative views regarding euthanasia than did physicians from other medical specialties. Similarly female physicians and orthodox physicians indicated more conservative views. Differences may be due to factors inherent in subspecialty education. We suggest that in light of the unique complexity and context of patient euthanasia requests, based on their training and professional expertise psychiatrists are well suited to take a prominent role in evaluating such requests to die and making a decision as to the relative importance of competing variables.

Quilty-Dunn et al.'s wide-ranging defense of the Language of Thought Hypothesis (LoTH) argues that vision traffics in abstract, structured representational formats. We agree: Vision, like language, is compositional – just as words compose into phrases, many visual representations contain discrete constituents that combine in systematic ways. Here, we amass evidence extending this proposal, and explore its implications for how vision interfaces with the rest of the mind.

The Self-Intimation thesis has it that whatever justificatory status a proposition has, i.e., whether or not we are justified in believing it, we are justified in believing that it has that status. The Infallibility thesis has it that whatever justificatory status we are justified in believing that a proposition has, the proposition in fact has that status. Jointly, Self-Intimation and Infallibility imply that the justificatory status of a proposition closely aligns with the justification we have about that justificatory status. Self-Intimation (...) has two noteworthy implications. First, assuming that we never have sufficient justification for a proposition and for its negation, we can derive Infallibility from Self-Intimation. Interestingly, there seems to be no equivalently simple way to derive Self-Intimation from Infallibility. This asymmetry provides reason for thinking that bottom-level justification rather than top-level justification drives the explanation for why the levels of justification align. Second, Self-Intimation suggests a counterintuitive treatment of information concerning what justificatory status a proposition has. It follows from Self-Intimation that we always have justification for the truth about whether a proposition is justified for us, and therefore, that higher-order evidence could change what we should believe on this matter only by misleading us. This permits forming beliefs about whether a proposition is justified for us without regard to higher-order evidence, and thus reveals a reason for thinking that top-level justification is evidentially inert.

Recent studies indicate that the processing of an unexpected word is costly when the initial, disconfirmed prediction was strong. This penalty was suggested to stem from commitment to the strongly predicted word, requiring its inhibition when disconfirmed. Additional studies show that comprehenders rationally adapt their predictions in different situations. In the current study, we hypothesized that since the disconfirmation of strong predictions incurs costs, it would also trigger adaptation mechanisms influencing the processing of subsequent strong predictions. In two experiments, participants (...) made speeded congruency judgments on two-word phrases in which the first word was either highly constraining or not. We manipulated the proportion of disconfirmed predictions in highly constraining contexts between participants. The results provide additional evidence of the costs associated with the disconfirmation of strong predictions. Moreover, they show a reduction in these costs when participants experience a high proportion of disconfirmed strong predictions throughout the experiment, indicating that participants adjust the strength of their predictions when strong prediction is discouraged. We formulate a Bayesian adaptation model whereby prediction failure cost is weighted by the participant’s belief about the likelihood of encountering the expected word, and show that it accounts for the trial-by-trial data.

This paper explores the sense in which correctness applies to belief-like imaginings. It begins by establishing that when we imagine, we ‘direct’ our imaginings at a certain imaginary world, taking the propositions we imagine to be assessed for truth in that world. It then examines the relation between belief-like imagining and positing truths in an imaginary world. Rejecting the claim that correctness, in the literal sense, is applicable to imaginings, it shows that the imaginer takes on, vis-à-vis the imaginary world, (...) the first-person perspective of a believer. Imaginings, it concludes, ‘mimic’ beliefs with respect to the property of being correct or incorrect by virtue of having true or false content. (shrink)

There is now considerable evidence that human sentence processing is expectation based: As people read a sentence, they use their statistical experience with their language to generate predictions about upcoming syntactic structure. This study examines how sentence processing is affected by readers' uncertainty about those expectations. In a self-paced reading study, we use lexical subcategorization distributions to factorially manipulate both the strength of expectations and the uncertainty about them. We compare two types of uncertainty: uncertainty about the verb's complement, reflecting (...) the next prediction step; and uncertainty about the full sentence, reflecting an unbounded number of prediction steps. We find that uncertainty about the full structure, but not about the next step, was a significant predictor of processing difficulty: Greater reduction in uncertainty was correlated with increased reading times. We additionally replicated previously observed effects of expectation violation, orthogonal to the effect of uncertainty. This suggests that both surprisal and uncertainty affect human RTs. We discuss the consequences for theories of sentence comprehension. (shrink)

Axiomatic measurement theories are commonly interpreted as claiming that, in order to quantify an empirical domain, the qualitative structure of data about that domain must be mapped to a numerical structure. Such mapping is supposed to be established independently, i.e., without presupposing that the domain can be quantified. This interpretation is based on two myths: that it is possible to independently infer the qualitative structure of objects from empirical data, and that the adequacy of numerical representations can only be justified (...) by mapping such qualitative structures to numerical ones. I dispel the myths and show that axiomatic measurement theories provide an inadequate characterization of the kind of evidence required to detect quantities. (shrink)

Can a heritability value tell us something about the weight of genetic versus environmental causes that have acted in the development of a particular individual? Two possible questions arise. Q1: what portion of the phenotype of X is due to its genes and what portion to its environment? Q2: what portion of X’s phenotypic deviation from the mean is a result of its genetic deviation and what portion a result of its environmental deviation? An answer to Q1 provides the full (...) information about X’s development, while an answer to Q2 leaves out a large portion unexplained—that portion which corresponds to the phenotypic mean. Q1 is unanswerable, but I show it is nevertheless legitimate under certain quantitative genetics models. With regard to Q2, opinions in the philosophical and biological literature differ as to its legitimacy. I argue that not only is it legitimate, but in particular, under a few simplifying assumptions, it allows for a quantitative probabilistic answer: for normally distributed quantitative traits with no G-E correlation or statistical G × E interaction, we can assess the probability that X’s genes had a greater effect than its environment on its deviation from the mean population value. This probability is expressed as a function the heritability and the individual’s phenotypic value; we can also provide a quantitative probabilistic answer to Q2 for an arbitrary individual where the probability is a function only of heritability.
