Academic Placement Data and Analysis (APDA), a project funded by the American Philosophical Association (APA) and headed by Carolyn Dicey Jennings (UC Merced), aims “to make information on academic job placement useful to prospective graduate students in philosophy.” The project has just been updated to include new data, which Professor Jennings describes in a post at New APPS. She also announces a new interactive data tool with which one can sift through and sort information. (from Daily Nous).

The visual system adapts to a wide range of visual features, from lower-level features like color and motion to higher-level features like causality and, perhaps, number. According to some, adaptation is a strictly perceptual phenomenon, such that the presence of adaptation licenses the claim that a feature is truly perceptual in nature. Given the theoretical importance of claims about adaptation, then, it is important to understand exactly when the visual system does and does not exhibit adaptation. Here, we take as (...) a case study one specific kind of adaptation: visual adaptation to size. Supported by evidence from four experiments, we argue that, despite robust effects of size adaptation in the lab, (1) size adaptation effects are phenomenologically underwhelming (in some cases, hardly appreciable at all), (2) some effects of size adaptation appear contradictory, and difficult to explain given current theories of size adaptation, and (3) prior studies on size adaptation may have failed to isolate size as the adapted dimension. Ultimately, we argue that while there is evidence to license the claim that size adaptation is genuine, size adaptation is a puzzling and poorly understood phenomenon. (shrink)

Does the visual system adapt to number? For more than fifteen years, most have assumed that the answer is an unambiguous “yes”. Against this prevailing orthodoxy, we recently took a critical look at the phenomenon, questioning its existence on both empirical and theoretical grounds, and providing an alternative explanation for extant results (the old news hypothesis). We subsequently received two critical responses. Burr, Anobile, and Arrighi rejected our critiques wholesale, arguing that the evidence for number adaptation remains overwhelming. Durgin questioned (...) our old news hypothesis — preferring instead a theory about density adaptation he has championed for decades — but also highlighted several ways in which our arguments do pose serious challenges for proponents of number adaptation. Here, we reply to both. We first clarify our position regarding number adaptation. Then, we respond to our critics’ concerns, highlighting seven reasons why we remain skeptical about number adaptation. We conclude with some thoughts about where the debate may head from here.

Debates surrounding the nature of mental disorder have tended to divide into an objectivist camp that takes psychiatric classification to be a value-free scientific matter, and a normativist camp that takes it to be irreducibly values-based. Here we present an overlooked distinction between _status_ and _constitution_. Questions of the form “What is x?” are ambiguous between status questions (“What gives something the status of an x?”), and constitution questions (“Given that something has the status of an x, what is it (...) made of?”). We elucidate this distinction in detail, and argue that normativism is uniquely well-placed to answer status questions while objectivism provides answers, where they are available, to constitution questions.

We extend results of Bonet, Buss and Pitassi on Bondy’s Theorem and of Nozaki, Arai and Arai on Bollobás’ Theorem by proving that Frankl’s Theorem on the trace of sets has quasipolynomial size Frege proofs. For constant values of the parametert, we prove that Frankl’s Theorem has polynomial size AC0-Frege proofs from instances of the pigeonhole principle.

Many people are concerned about the legitimacy of digital technology companies like Meta. In this paper we show that two existing models for characterizing power – sovereign power and structural power – are inadequate when it comes to digital technology companies. This is because they fail to accommodate something crucial: the uniquely empowering nature of digital power. Companies like Meta empower users to interact by providing them with versatile systems defined by minimalist permission structures. Drawing on Searle’s theory of institutions (...) and Hart’s theory of law, we show how these permission structures facilitate the creation of new powers, as well as new institutions, through the emergence and recognition of new social norms. This means we must ask how entities that provide us with such versatile – and thus unsteerable – means of empowerment can come to be legitimate. We argue that a custodial framework for digital legitimacy can assign responsibility for the patterns of empowerment that are sustained by companies like Meta. (shrink)

Two important questions arise concerning the properties that constitute the phenomenal characters of our experiences: first, where these properties exist, and, second, whether they are tied to our consciousness of them. Such properties can either exist externally to the perceiving subject, or internally to her. This article argues that phenomenal characters, and specifically the phenomenal characters of colours, may exist independently of consciousness and that they are internal to the subject. We defend this combination of claims against a recent criticism (...) according to which the unconscious phenomenal character of colours exists externally to the subject. We defend internalism about (potentially unconscious) phenomenal character by appealing to recent neuroscientific and behavioural evidence, and by rejecting the claim that externalism about phenomenal character is dialectically in a better position than internalism. In addition, we briefly present certain difficulties for externalist views of phenomenal character. These concern cases where the perceptual relation fails, but a perceptual experience still results. These points suffice to defuse the externalist critique of our view, and support the internalist variant of the consciousness-independence claim as the most plausible account of the unconscious phenomenal character of colours.

Recent studies suggest that meta-learning may provide an original solution to an enduring puzzle about whether neural networks can explain compositionality – in particular, by raising the prospect that compositionality can be understood as an emergent property of an inner-loop learning algorithm. We elaborate on this hypothesis and consider its empirical predictions regarding the neural mechanisms and development of human compositionality.

This particular roundtable falls at the end of a four-year networking project (COST Action IS1307 New Materialism: Networking European Scholarship on ‘How Matter Comes to Matter’) and reflects upon the genealogies of new materialism and how these flow into the individual working practices of participants. The texts below were contributed remotely via email by members of the group, following face-to-face meetings in Barcelona, Maribor, Warsaw, Liverpool, Paris and Utrecht. Authors were unaware of each other’s responses and in this way the (...) dialogue has unfolded a little like a game of Exquisite Corpse or Consequences, with questions acting like a trail of breadcrumbs to follow. Accordingly, the text is the product of a partially bounded experimental system ‘designed to give unknown answers to questions that the experimenters themselves are not yet able to clearly ask’ (Rheinberger 1997: 28). Thus, it both ruminates upon work to date and is intended to generate novel responses from authors and readers alike. (shrink)

Cette étude vise à explorer la possibilité d'une pédagogie alternative non fondée sur la subjectivité moderne, basée sur la théorie du deuil de Judith Butler. Le sujet méritocratique favorisé par l'éducation d'aujourd'hui ne peut pas répondre par le deuil à la mort des autres, qui réveille la précarité et la douleur de la vie, pour maintenir un optimisme face à soi et à l'avenir. Selon Judith Butler, les sujets qui pleurent la mort des autres, contrairement aux sujets modernes autonomes, sont (...) des sujets vulnérables et hétéronomes qui émergent de telle sorte que la frontière exclusive avec les autres est brisée, et le deuil qu'ils accomplissent est une cohabitation d'autres vulnérables. Il sert de base à la recherche. Sur cette base, une pédagogie alternative est proposée. La pédagogie du deuil (1) est basée sur la vulnérabilité plutôt que sur l'autonomie ou l'indépendance du sujet, (2) utilise la critique comme outil pour découvrir des vies qui ne peuvent pas être pleurées et crée une politique commune qui les englobe. (3) Le deuil de la mort d'autrui est constamment tenté sur la base de l'éthique de l'échec qui ne peut jamais être achevé. La pédagogie du deuil est une éducation qui restaure les sujets effondrés et épuisés de la société moderne, une éducation qui ravive la valeur des émotions aliénées telles que la tristesse, la douleur et la peur, et qui fait finalement partie de l'éducation démocratique qui cherche à « vivre ensemble ».

We prove the first unconditional consistency result for superpolynomial circuit lower bounds with a relatively strong theory of bounded arithmetic. Namely, we show that the theory [Formula: see text] is consistent with the conjecture that [Formula: see text], i.e. some problem that is solvable in non-deterministic exponential time does not have polynomial size circuits. We suggest this is the best currently available evidence for the truth of the conjecture. The same techniques establish the same results with [Formula: see text] replaced (...) by the class of problems decidable in non-deterministic barely superpolynomial time such as [Formula: see text]. Additionally, we establish a magnification result on the hardness of proving circuit lower bounds. (shrink)

Four Views on Christian Metaphysics presents four prominent views held among Christians today on the major questions in philosophical metaphysics. What is the nature of existence itself? What is it for something to exist? What are universals? What is the soul? How do these things relate to God, in light of special and general revelation? The four Christian perspectives presented in this book are: Platonism, Aristotelianism, idealism, and postmodernism. The purpose of this book is to help Christians think deeply and (...) carefully about a Christian view of the ultimate nature of reality and our place in it. (shrink)

Al-Abharī’s Isagoge is an introductory primer in logic which has received numerous commentaries, each geared towards students of various levels of familiarity with this instrumental science. Al-Fanārī’s advanced commentary on the Isagoge, called al-Fawāʾid al-Fanāriyya, has confounded students of logic for centuries due to its terse and dense style as well as the presumption that the reader knows well the science of disputation along with the subtle interpretive disagreements discussed in other texts and commentaries. Sājaqlīzādah’s primer on disputation entitled al-Waladiyya, (...) written nearly 300 years after al-Fanārī’s commentary, provides useful examples of the possible claims, objections, and defenses available to one making scholarly claims in the form of definitions, classifications, and propositional assents or syllogistic reasoning. In this article, I explore several instances of al-Fanārī’s use of the terms and methods of disputation in order to defend definitions or classifications found al-Abharī’s Isagoge. I aim to identify the specific disputational moves used by al-Fanārī, drawing from those described by Sājaqlīzādah. In doing so, I demonstrate that this important advanced commentary on a popular logic primer is best understood through the lens of disputation. I also argue that Sājaqlīzādah’s suggested methods of making claims, objections, and defenses can be transposed in whole or in part from one category of claim—definitions, classifications, assents—to another, indicating a greater complexity of disputational possibilities than his introductory handbook provides.

Sam Harris dismantles the most common justification for religious faith--that a moral system cannot be based on science.

What factors shape the movement of systems of thought from one historical‐cultural context to another? This paper provides a preliminary answer to this question by constructing an analytic framework drawn from the sociology of philosophy, and it uses this framework to consider the prospects for the contemporary transposition of Confucianism from China to America. The central, though still provisional, conclusion is that while global power dynamics matter, the particular conditions of the “philosophical fields” of both the original and the recipient (...) locations are of primary importance in determining the extent and significance of any particular case of philosophical transposition. Therefore, due to the dynamics of the philosophical fields in both countries, it is unlikely that Confucianism will gain greater intellectual and political influence in the United States. (shrink)

This book explores the extent to which children engage with morality within their everyday lives.

Inspiring teachers to teach with more spontaneity and creativity within a highly constrained educational environment, this text demonstrates through descriptive stories strategies for emergent teaching. The text is consistent with the theoretical understandings and research in the complexity sciences but takes a narrative approach, giving examples through stories, myths, and parables.

In an interesting experimental study, Bonini et al. (1999) present partial support for truth-gap theories of vagueness. We say this despite their claim to find theoretical and empirical reasons to dismiss gap theories and despite the fact that they favor an alternative, epistemic account, which they call ‘vagueness as ignorance’. We present yet more experimental evidence that supports gap theories, and argue for a semantic/pragmatic alternative that unifies the gappy supervaluationary approach together with its glutty relative, the subvaluationary approach.

In this enlightening book, Sam Harris argues that free will is an illusion but that this truth should not undermine morality or diminish the importance of social and political freedom; indeed, this truth can and should change the way we think about some of the most important questions in life.

Current models of auditory verbal hallucinations tend to focus on the mechanisms underlying their occurrence, but often fail to address the content of the auditory experience. In other words, they tend to ask why there are AVHs at all, instead of asking why, given that there are AVHs, they have the properties that they have. One such property, which has been largely overlooked and which we will focus on here, is why the voices are often experienced as coming from agents, (...) and often specific, individualised agents. In this article, we argue not only that the representation of agents is important in accurately describing many cases of AVH, but also that deeper reflection on what is involved in the representation of agents has potentially vital consequences for our aetiological understanding of AVH, namely, for understanding how and why AVHs come about.

Kant proclaimed that all theodicies must fail in ?On the Miscarriage of All Philosophical Trials in Theodicy?, but it is mysterious why he did so since he had developed a theodicy of his own during the critical period. In this paper, I offer an explanation of why Kant thought theodicies necessarily fail. In his theodicy, as well as in some of his works in ethics, Kant explained moral evil as resulting from unavoidable limitations in human beings. God could not create (...) finite beings without such limitations and so could not have created humans that were not prone to committing immoral acts. However, the work of Carl Christian Eberhard Schmid showed Kant that given his own beliefs about freedom and the nature of responsibility one could not account for moral evil in this way without tacitly denying that human beings were responsible for their actions. This result is significant not only because it explains an otherwise puzzling shift in Kant's philosophy of religion, but also because it shows that the theodicy essay provides powerful evidence that Kant's thinking about moral evil and freedom underwent fundamental shifts between early works such as the Groundwork and later works like the Religion within the Limits of Mere Reason.

Standard approaches to counterfactuals in the philosophy of explanation are geared toward causal explanation. We show how to extend the counterfactual theory of explanation to non-causal cases, involving extra-mathematical explanation: the explanation of physical facts by mathematical facts. Using a structural equation framework, we model impossible perturbations to mathematics and the resulting differences made to physical explananda in two important cases of extra-mathematical explanation. We address some objections to our approach.

Think of a number, any number, or properties like fragility and humanity. These and other abstract entities are radically different from concrete entities like electrons and elbows. While concrete entities are located in space and time, have causes and effects, and are known through empirical means, abstract entities like meanings and possibilities are remarkably different. They seem to be immutable and imperceptible and to exist "outside" of space and time. This book provides a comprehensive critical assessment of the problems raised (...) by abstract entities and the debates about existence, truth, and knowledge that surround them. It sets out the key issues that inform the metaphysical disagreement between platonists who accept abstract entities and nominalists who deny abstract entities exist. Beginning with the essentials of the platonist–nominalist debate, it explores the key arguments and issues informing the contemporary debate over abstract reality: arguments for platonism and their connections to semantics, science, and metaphysical explanation the abstract–concrete distinction and views about the nature of abstract reality epistemological puzzles surrounding our knowledge of mathematical entities and other abstract entities. arguments for nominalism premised upon concerns about paradox, parsimony, infinite regresses, underdetermination, and causal isolation nominalist options that seek to dispense with abstract entities. Including chapter summaries, annotated further reading, and a glossary, _Entities_ is essential reading for anyone seeking a clear and authoritative introduction to the problems raised by abstract entities.

Van Fraassen's constructive empiricism is presently the most influential and well-developed alternative to scientific realism. In this paper I argue that a reasonable condition on the distinction between belief and agnosticism prevents van Fraassen from claiming that we can be agnostic about what a theory says about unobservable entities while simultaneously accepting that theory. The upshot is that we must find some other way to do justice both to the argument for constructive empiricism and to van Fraassen's cogent criticisms of (...) scientific realism. I suggest that a highly attractive alternative is founded upon semantic anti-realism, and that empiricists should develop this alternative. (shrink)

Psychiatric researchers typically assume that the modelling of psychiatric symptoms is not influenced by psychiatric categories; symptoms are modelled and then grouped into a psychiatric category. I highlight this primarily through analysing research domain criteria. RDoC’s importance makes it worth scrutinizing, and this assessment also serves as a case study with relevance for other areas of psychiatry. RDoC takes inadequacies of existing psychiatric categories as holding back causal investigation. Consequently, RDoC aims to circumnavigate existing psychiatric categories by directly investigating the (...) causal basis of symptoms. The unique methodological approach of RDoC exploits the supposed lack of influence of psychiatric categories on symptom modelling, taking psychiatric symptoms as the same regardless of which psychiatric category is employed or if no psychiatric category is employed. But this supposition is not always true. I will show how psychiatric categories can influence symptom modelling, whereby identical behaviours can be considered as different symptoms based on an individual’s psychiatric diagnosis. If the modelling of symptoms is influenced by psychiatric categories, then psychiatric categories will still play a role, a situation which RDoC researchers explicitly aim to avoid. I discuss four ways RDoC could address this issue. This issue also has important implications for factor analysis, cluster analysis, modifying psychiatric categories, and symptom based approaches.

Time is woven into the fabric of our lives. Everything we do, we do in and across time. It is not just that our lives are stretched out in time, from the moment of birth to the moment of our death. It is that our lives are stories. We make sense of ourselves, today, by understanding who we were yesterday, and the day before, and the day before that; by understanding what we did and why we did it. Our memories (...) shape our present selves, since we are the product of who we were, and who we remember being. Yet who we are lasts for but a moment. It is who we will be that demands attention. We are forever projecting ourselves into the future. We painstakingly plan for the needs of our future selves, all the while knowing that while what we do will make those future selves who they are, still, our future selves are elusive. So it is not simply that we happen to live our lives in time, the way, say, one might happen to live in Australia, or Singapore. It is hard to fathom how things could be otherwise. What would it be to live a life without time? Yet time itself is intangible. Though we are keenly aware of what has been ‒ of pain and loss, regret and pride ‒ and of what might be ‒ of anticipation, and dread, and longing ‒ time itself seems unaffected by anything we do. Though we can anticipate a future birthday cake, time itself cannot be tasted. Though we can dread a future dentist’s appointment, time itself cannot be touched. Though we remember the crunching of leaves this past autumn, time itself cannot be heard. How can it be that something so central to each of us, to who we are, and what we care about, can be so spectral? What, in the end, is time? Is time real, like a substance in which each of us, like insects in amber, finds ourselves trapped? Is time a dimension through which we can move? Is time not a thing at all, but some connection between events? If time is real, what is it like? Does it flow like a river, taking each of us prisoner in its current, washing us ever closer to the end of our lives? Is time like a cresting wave, coming ever closer to each of us from the future, engulfing us, and then receding into the past? Or is time static? Like a one-way road that each of us might wander, with no chance to turn back? Or perhaps time is like none of these things. Perhaps time is more like space; something we can navigate freely, so that we can visit different times just like we visit different places. Perhaps we can we travel in time the way we can travel in space. These questions, and many more, are the focus of this book. Now, you might wonder what philosophers are doing writing a book about time. Surely that’s a job for physicists! It is true: a great deal of what we know about time stems from our understanding of physics. However, even in physics we find that there are questions about time that go unanswered. Moreover, increasingly, physicists are turning to philosophers for help in understanding the role that time plays in current physical theories. Our goal is to get the reader up to speed on some of the central issues that influence our understanding of time so that they too may play a role in this ongoing discussion between science and philosophy. We hope that in doing so it will become clear what philosophy can bring to the study of time. There is a natural narrative in philosophy regarding the study of time, and we have chosen to organise this book according to that narrative. However, the book may also be approached in a ‘choose-your-own adventure’ spirit. While later chapters build on material introduced in earlier chapters, you can skip around, reading the book in any order you choose. For the instructor, this means that she can design her course around this book in any number of ways, depending on the particular topic she wishes to focus on. (shrink)

A proposed empirical criterion for task susceptibility to introspective awareness distinguishes cognitive processes of which one cannot be aware from those of which one can be aware. The empirical criterion for task susceptibility to awareness effects proposes that there are tasks which cannot be affected by awareness of the rules constituting the tasks. These criteria were applied to research programmes in rule-learning in which past studies in the area of learning without awareness were included as well as current research in (...) implicit learning. The principal question addressed in these studies is whether or not rule-learning can occur without awareness. An historical review showed that rule-learning occurred in tasks which were both susceptible and insusceptible to introspective awareness and to awareness effects. Accordingly, it has been proposed that rather than attempt to decide theoretically and empirically between the opposing hypotheses—that of “cognitive learning” on the one hand, which assumes that awareness is a necessary condition for rule-learning, and that of “automatic learning” on the other, which assumes direct, automatic and unconscious processes—efforts should rather be directed toward developing a theoretical approach which is based on both conscious and unconscious processes. However, an approach of this kind encounters severe problems, such as the generation of contradictory predictions, which result from the employment of several incongruent and irreconcilable models of explanation. The criteria for task susceptibility offer a way out of these difficulties. (shrink)
