Many theorists have dismissed a priori the idea that distributional information could play a significant role in syntactic category acquisition. We demonstrate empirically that such information provides a powerful cue to syntactic category membership, which can be exploited by a variety of simple, psychologically plausible mechanisms. We present a range of results using a large corpus of child‐directed speech and explore their psychological implications. While our results show that a considerable amount of information concerning the syntactic categories can be obtained (...) from distributional information alone, we stress that many other sources of information may also be potential contributors to the identification of syntactic classes.

Despite thermodynamic, bioenergetic and phylogenetic failings, the 81‐year‐old concept of primordial soup remains central to mainstream thinking on the origin of life. But soup is homogeneous in pH and redox potential, and so has no capacity for energy coupling by chemiosmosis. Thermodynamic constraints make chemiosmosis strictly necessary for carbon and energy metabolism in all free‐living chemotrophs, and presumably the first free‐living cells too. Proton gradients form naturally at alkaline hydrothermal vents and are viewed as central to the origin of life. (...) Here we consider how the earliest cells might have harnessed a geochemically created proton‐motive force and then learned to make their own, a transition that was necessary for their escape from the vents. Synthesis of ATP by chemiosmosis today involves generation of an ion gradient by means of vectorial electron transfer from a donor to an acceptor. We argue that the first donor was hydrogen and the first acceptor CO2. (shrink)

Much research on judgment and decision making has focussed on the adequacy of classical rationality as a description of human reasoning. But more recently it has been argued that classical rationality should also be rejected even as normative standards for human reasoning. For example, Gigerenzer and Goldstein and Gigerenzer and Todd argue that reasoning involves “fast and frugal” algorithms which are not justified by rational norms, but which succeed in the environment. They provide three lines of argument for this view, (...) based on: the importance of the environment; the existence of cognitive limitations; and the fact that an algorithm with no apparent rational basis, Take-the-Best, succeeds in an judgment task. We reconsider –, arguing that standard patterns of explanation in psychology and the social and biological sciences, use rational norms to explain why simple cognitive algorithms can succeed. We also present new computer simulations that compare Take-the-Best with other cognitive models. Although Take-the-Best still performs well, it does not perform noticeably better than the other models. We conclude that these results provide no strong reason to prefer Take-the-Best over alternative cognitive models. (shrink)

It is often assumed that cognitive science is built upon folk psychology, and that challenges to folk psychology are therefore challenges to cognitive science itself. We argue that, in practice, cognitive science and folk psychology treat entirely non-overlapping domains: cognitive science considers aspects of mental life which do not depend on general knowledge, whereas folk psychology considers aspects of mental life which do depend on general knowledge. We back up our argument on theoretical grounds, and also illustrate the separation between (...) cognitive scientific and folk psychological phenomena in a number of cognitive domains. We consider the methodological and theoretical significance of our arguments for cognitive science research. (shrink)

ABSTRACT Because Pastafarianism – or the Church of the Flying Spaghetti Monster – is a parodic religion, common sense suggests its ‘adherents’ should not receive exemptions. However, the prima facie case for excluding Pastafarians is complicated by the fact that many assert their religion is as legitimate as any other religion and that their beliefs are genuine. Indeed, Pastafarians have already obtained exemptions in various countries. Taking the dominant liberal egalitarian, integrity‐based approach to exemptions, this article investigates whether there is (...) a principled, objective basis for excluding Pastafarians that accounts for their assertions. To that end, I examine four tests: a religion, seriousness, obligation, and sincerity test. I assess whether each test can actually exclude Pastafarians, and if it could, can it do so in a way that is consistent with liberal egalitarian commitments. I argue that only a sincerity test – based on consistent behaviour and a willingness to bear the costs of one's beliefs – satisfies both of these conditions, but, on a weak and contingent basis.

This book offers the first comparative account of the changes and stabilities of public perceptions of science within the US, France, China, Japan, and across Europe over the past few decades. The contributors address the influence of cultural factors; the question of science and religion and its influence on particular developments (e.g. stem cell research); and the demarcation of science from non-science as well as issues including the incommensurability versus cognitive polyphasia and the cognitive (in)tolerance of different systems of knowledge.

Liberal neutrality is assumed to pertain to rival conceptions of the good. The nature of the rivalry between conceptions of the good is pivotal to the coherence, scope and realisation of liberal neutrality. Yet, liberal theorists have said very little about rivalry. This paper attempts to fill this gap by reviewing three conceptions of rivalry: incompatibility rivalry, intra-domain rivalry and state power rivalry. I argue that state power rivalry is the morally relevant conception of rivalry, and that it has significant (...) implications for the scope and realisation of liberal neutrality. I conclude that in the light of state power rivalry, the only feasible liberal neutral state is a very minimal one. (shrink)

What does it mean to ‘drop out’ of therapy? Many definitions of ‘dropout’ have been proposed, but the most widely accepted is the client ending treatment without agreement of their therapist. However, this is in some ways an external criterion that does not take into account the client’s experience of therapy, or reasons for ending it prematurely. This study aimed to identify whether there were more meaningful categories of dropout than the existing dropout definition, and to test whether this refined (...) categorisation of dropout was associated with clinical outcomes. This mixed-methods study used a subset of data from the IMPACT trial, which investigated psychological therapies for adolescent depression. Adolescents were randomly allocated to a treatment arm (Brief Psychosocial Intervention; Cognitive-Behavioural Therapy; Short-Term Psychoanalytic Psychotherapy). The sample for this study comprised 99 adolescents, aged 11-17 years. 32 were classified as having dropped out of treatment and participated in post-therapy qualitative interviews about their experiences of therapy. For 26 dropout cases, the therapist was also interviewed. 67 cases classified as having completed treatment were included to compare their outcomes to dropout cases. Interview data for dropout cases were analysed using ideal type analysis. Three types of dropout were constructed: ‘dissatisfied’ dropout, ‘got-what-they-needed’ dropout, and ‘troubled’ dropout. ‘Dissatisfied’ dropouts reported stopping therapy because they did not find it helpful. ‘Got-what-they-needed’ dropouts reported stopping therapy because they felt they had benefitted from therapy. ‘Troubled’ dropouts reported stopping therapy because of a lack of stability in their lives. The findings indicate the importance of including the perspective of clients in definitions of drop out, as otherwise there is a risk that the heterogeneity of 'dropout' cases may mask more meaningful distinctions. Clinicians should be aware of the range of issues experienced by adolescents in treatment that lead to disengagement. Our typology of dropout may provide a framework for clinical decision-making in managing different types of disengagement from treatment. (shrink)

Planctomycetes, Verrucomicrobia and Chlamydia are prokaryotic phyla, sometimes grouped together as the PVC superphylum of eubacteria. Some PVC species possess interesting attributes, in particular, internal membranes that superficially resemble eukaryotic endomembranes. Some biologists now claim that PVC bacteria are nucleus‐bearing prokaryotes and are considered evolutionary intermediates in the transition from prokaryote to eukaryote. PVC prokaryotes do not possess a nucleus and are not intermediates in the prokaryote‐to‐eukaryote transition. Here we summarise the evidence that shows why all of the PVC traits (...) that are currently cited as evidence for aspiring eukaryoticity are either analogous (the result of convergent evolution), not homologous, to eukaryotic traits; or else they are the result of horizontal gene transfers.

We respond to Morris and Richardson 's claim that Pickering and Chater's arguments about the lack of a relation between cognitive science and folk psychology are flawed. We note that possible controversies about the appropriate uses for the two terms do not affect our arguments. We then address their claim that computational explanation of knowledge-rich processes has proved possible in the domains of problem solving, scientific discovery, and reasoning. We argue that, in all cases, computational explanation is only possible for (...) aspects of those processes that do not make reference to general knowledge. We conclude that consideration of the issues raised by Morris and Richardson reinforces our original claim that there are two fundamentally distinct projects for understanding the mind, one based on justification, and the other on computational explanation, and that these apply to non-overlapping aspects of mental life.

Several psychosocial models have been proposed to explain the etiology of eating disorders and obesity separately despite research suggesting they should be conceptualized within a shared theoretical framework. The objective of the current study was to test an integrated comprehensive model consisting of a host of common risk and protective factors expected to explain both eating and weight disorders simultaneously in a large school-based sample of adolescents. Data were collected from 3,043 youth from 41 schools in the Ottawa region, Canada. (...) Working with interested school staff, validated self-report scales in the form of a questionnaire booklet were administered to participating students to assess several understood risk and protective factors common to both eating disorders and obesity. Anthropometric measurements of weight and height were taken at the end of the questionnaire administration period by trained research staff. Structural equation modeling with cross-validation was used to test the hypothesized model. Findings demonstrated that dysregulated eating was associated with both eating disorder and weight status with diet culture and emotion dysregulation directly associated with some of these disordered eating patterns. It equally pointed to how lifestyle made up of high sedentary behaviors, low vigorous exercise and varied eating patterns contributed to both emotion dysregulation and poor body image which subsequently affected eating issues and weight status simultaneously, signaling the complex interplay of psychosocial factors that underlie these concerns. This study provides evidence for an integrated psychosocial model consisting of socio-environmental, psychological, and behavioral factors may best explain the complex interplay of risk and protective factors influencing eating disorders and obesity. It equally highlights understanding the direct and indirect effects of some of the most salient risk factors involved in eating and weight-related concerns, including the strong effects of diet culture and stressors such as weight-based teasing, providing interventionalists evidence of important risk factors to consider targeting in eating disorder and weight-based prevention efforts.

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)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

Maurice Blanchot, in his essay on Hülderlin, calls our age “an empty time.” Martin Heidegger, paraphrasing Hülderlin's monumental elegy “Bread and Wine,” speaks of our “destitution.” In Hülderlin's language, we are experiencing the absence of the “gods who have fled.” The Western world, according to these authors, finds itself in a crisis of alienation: the old beliefs, values, and worldviews that used to anchor us in the world have been long rent asunder, and we cast about in vain for (...) a ground that isn't there. Yet, as Heidegger writes, our time is “no longer able even to experience its own…. (shrink)

The problem of free will has fascinated philosophers since ancient times: Do we have free will, or at least the kind of free will that seems necessary for moral responsibility? Does determinism - the idea that everything that happens is necessitated to happen, given the past and the laws of nature - threaten the commonly held assumption that we are indeed free and morally responsible? Although these questions have been widely discussed in the past, the present volume offers a variety (...) of new perspectives from philosophers who have made significant contributions to this debate over recent years, including Derk Pereboom, Robert Kane, Ishtiyaque Haji, Michael McKenna, John Martin Fischer, David Widerker and Saul Smilansky. The emphasis in these essays is not merely on free will, but on allied notions such as moral responsibility, moral obligation, fairness and meaningfulness, and on whether any room can be made for these notions in a deterministic or an indeterministic universe.

In this paper, I present and criticize Ted Kaczynski’s (“The Unabomber”) theory that industrialization has been terrible for humanity, and that we should use any means necessary, including violent means, to induce a return to pre‐industrial ways of living. Although Kaczynski’s manifesto, Industrial society and its future, has become widely known, his ideas have never before been subject to careful philosophical criticism. In this paper I show how Kaczynski’s arguments rely on a number of highly implausible philosophical premises. I further (...) make the case that, although his theory as a whole should be rejected, Kaczynski raises a number of worries about technological development that ought to receive serious attention. Some of these worries have recently come to be shared by prominent defenders of human enhancement, including Nick Bostrom and Julian Savulescu. In the last section I indicate why I believe it is important that academic philosophers scrutinize ideas that motivate acts of violence. (shrink)

The political actions of Martin Heidegger raise a compelling question to those concerned with philosophy: How was one of the most important philosophers of the 20th century willing to ally himself with Nazism and what does this mean for philosophy? This question has been raised and brushed aside from the end of the Second World War, when Heidegger was formally accused for his involvement with Hitler's regime and forbidden to attain any official teaching position henceforth. Important thinkers, like his (...) colleague and friend in the pre-war years, Karl Jaspers. testified then against him. But Heidegger's fame rose again above his indignity in the 1950s, when Hannah Arendt in the USA and Jean-Paul Sartre in France, among others, began once again to spread the word of his philosophy and translate his works. These problems have recently intensified after the posthumous publication of Heidegger's Black Notebooks (Schwarze Hefte) in 2014, containing his notes from 1931-1941. Their publication caused seismic tremors in the field of philosophy, with Heidegger's opponents considering themselves finally vindicated by his own pen, and his supporters trying to separate thinking from actual life. However, the influence of Heidegger's thought - as well as that of other representatives of German anti-humanist nationalistic conservatism, such as Oswald Spengler - continues to spread, not only in academic but also in broader social and political circles. In the face of this spreading influence, which is combined with the influence of some disciples such as Nick Land or Giorgio Agamben, a biographical-type confrontation is not enough. We should confront Heidegger directly at the core of his philosophy. We cannot afford to ignore him or bury him under superficial gossip. Instead, we should confront him philosophically. We might be able to clear the ground for such a confrontation, if we resort to the philosophical concepts of autonomy, temporality, and human freedom. In my opinion, the most important philosophical challenge to Heideggerian thought, in this context, has been expressed by Cornelius Castoriadis. In the following chapters, I will argue in favor of this position, outlining the Castoriadian philosophy of time in contrast to the Heideggerian and highlighting the main points of their opposition. The book is divided into two parts. Part one, "Castoriadis against Heidegger" deals with the basic concepts and arguments of both philosophers around human existence, the individual, society, and temporality. We start by presenting Heidegger's scandal in the social-historical context but also with the help of Hannah Arendt's last assessment of the thinker. We move on to outline the basic concepts and structures of Heidegger's philosophical thinking in parallel with Castoriadis' criticism as regards politics, ontology and technoscience. Part two, "Time and existence" first examines the relevant approaches of Lukacs and Ricoeur in comparison to Heidegger and Castoriadis, to elucidate the basic concept of temporality and then presents an outline of Castoriadis' insights on time and existence, before finally applying these concepts to contemporary social-historical phenomena that redefine and transform human existence and social temporalities, like space exploration, digital cyberspaces and online communications. //////// -/- "This book is a tour de force that excites those who agree or disagree with the philosophy of Heidegger.

As Holderlin was to Martin Heidegger and Mallarme to Jacques Derrida, so is H.P. Lovecraft to the Speculative Realist philosophers. Lovecraft was one of the brightest stars of the horror and science fiction magazines, but died in poverty and relative obscurity in the 1930s. In 2005 he was finally elevated from pulp status to the classical literary canon with the release of a Library of America volume dedicated to his work. The impact of Lovecraft on philosophy has been building (...) for more than a decade. Initially championed by shadowy guru Nick Land at Warwick during the 1990s, he was later discovered to be an object of private fascination for all four original members of the twenty-first century Speculative Realist movement. In this book, Graham Harman extracts the basic philosophical concepts underlying the work of Lovecraft, yielding a weird realism capable of freeing continental philosophy from its current soul-crushing impasse. Abandoning pious references by Heidegger to Holderlin and the Greeks, Harman develops a new philosophical mythology centered in such Lovecraftian figures as Cthulhu, Wilbur Whately, and the rat-like monstrosity Brown Jenkin. The Miskatonic River replaces the Rhine and the Ister, while Holderlin's Caucasus gives way to Lovecraft's Antarctic mountains of madness. (shrink)

_Anthropic Bias_ explores how to reason when you suspect that your evidence is biased by "observation selection effects"--that is, evidence that has been filtered by the precondition that there be some suitably positioned observer to "have" the evidence. This conundrum--sometimes alluded to as "the anthropic principle," "self-locating belief," or "indexical information"--turns out to be a surprisingly perplexing and intellectually stimulating challenge, one abounding with important implications for many areas in science and philosophy. There are the philosophical thought experiments and paradoxes: (...) the Doomsday Argument; Sleeping Beauty; the Presumptuous Philosopher; Adam & Eve; the Absent-Minded Driver; the Shooting Room. And there are the applications in contemporary science: cosmology ; evolutionary theory ; the problem of time's arrow ; quantum physics ; game-theory problems with imperfect recall ; even traffic analysis. _Anthropic Bias_ argues that the same principles are at work across all these domains. And it offers a synthesis: a mathematically explicit theory of observation selection effects that attempts to meet scientific needs while steering clear of philosophical paradox. (shrink)

This article argues that there can be epistemic dilemmas: situations in which one faces conflicting epistemic requirements with the result that whatever one does, one is doomed to do wrong from the epistemic point of view. Accepting this view, I argue, may enable us to solve several epistemological puzzles.

In dieser Marburger Vorlesung aus dem Wintersemester 1924/25 stellt sich Heidegger die Aufgabe, Platons Spatdialog "Sophistes" im Ausgang von Aristoteles verstandlich zu machen. Zentrum des einleitenden Aristoteles-Teils ist die Folge der dianoethischen Tugenden im VI. Buch der "Nikomachischen Ethik", in der Heidegger die sich aufsteigernde Stufenfolge eines Entbergens erkennt und demgemass den Primat der "Physis" aus der Uberlegenheit ihres Entbergens begrundet. Damit legt Heidegger die Zusammengehorigkeit von Sein und Wahrheit als Horizont des aristotelisch-griechischen Philosophierens frei und gewinnt so den "Boden", (...) aus dem die platonische Seinsforschung, wie sie im "Sophistes" vorliegt, erwachsen ist. Dementsprechend stellt sich Heidegger im Hauptteil die Aufgabe, in fortlaufender Interpretation des "Sophistes" konkret zu zeigen, dass und wie Platons Ontologie aus dem Entbergen erwachsen ist. Die Vorlesung bezeugt, dass Heidegger die in seinem fruhen Hauptwerk "Sein und Zeit" gestellte Frage nach dem "Sinn von Sein", d.h. nach der Un-verborgenheit des Seins in der Auseinandersetzung mit der philosophischen Uberlieferung gewonnen hat.

This paper investigates the significance of T-duality in string theory: the indistinguisha- bility with respect to all observables, of models attributing radically different radii to space – larger than the observable universe, or far smaller than the Planck length, say. Two interpretational branch points are identified and discussed. First, whether duals are physically equivalent or not: by considering a duality of the familiar simple harmonic oscillator, I argue that they are. Unlike the oscillator, there are no measurements ‘outside’ string theory (...) that could distinguish the duals. Second, whether duals agree or disagree on the radius of ‘target space’, the space in which strings evolve according to string theory. I argue for the latter position, because the alternative leaves it unknown what the radius is. Since duals are physically equivalent yet disagree on the radius of target space, it follows that the radius is indeterminate between them. Using an analysis of Brandenberger and Vafa (1989), I explain why – even so – space is observed to have a determinate, large radius. The conclusion is that observed, ‘phenomenal’ space is not target space, since a space cannot have both a determinate and indeterminate radius: instead phenomenal space must be a higher-level phenomenon, not fundamental.

What is it for a person to have style? Philosophers working in action theory, ethics, and aesthetics are surprisingly quiet on this question. I begin by considering whether theories of artistic style shed any light on it. Many philosophers, artists, and art historians are attracted to some version of the view that artistic style is the expression of personality. I clarify this view and argue that it is implausible for both artistic style and, suitably modified, personal style. In fact, both (...) theories of style crack along the same line, which suggests that they can indeed be mutually illuminating. I articulate and defend a view of personal style according to which, roughly, having style is a matter of expressing one’s ideals. I show how this illuminates the widely neglected value of personal style and propose a new, analogous theory of individual artistic style: artistic style is the expression of the ideals the artist has for her art.

The Sleeping Beauty problem is test stone for theories about self-locating belief, i.e. theories about how we should reasons when data or theories contain indexical information. Opinion on this problem is split between two camps, those who defend the "1/2 view" and those who advocate the "1/3 view". I argue that both these positions are mistaken. Instead, I propose a new "hybrid" model, which avoids the faults of the standard views while retaining their attractive properties. This model _appears_ to violate (...) Bayesian conditionalization, but I argue that this is not the case. By paying close attention to the details of conditionalization in contexts where indexical information is relevant, we discover that the hybrid model is in fact consistent with Bayesian kinematics. If the proposed model is correct, there are important lessons for the study of self-location, observation selection theory, and anthropic reasoning. (shrink)

This article compares the concept of habitus, as formulated in the work of Mauss and Bourdieu, with the concept of habit, as formulated in the work of Merleau-Ponty and Dewey. The rationale for this, on one level, is to seek to clarify these concepts and any distinction that there may be between them – though the article notes the wide variety of uses of both concepts and suggests that these negate the possibility of any definitive definitions or contrasts. More centrally, (...) however, the purpose of the comparison is to draw out a number of important issues and debates which, it is argued, further work must address if the concepts of habit and habitus are to continue to prove useful and illuminating in social science.

Hyman (1999, 2006) argues that knowledge is best conceived as a kind of ability: S knows that p iff S can φ for the reason that p. Hyman motivates this thesis by appealing to Gettier cases. I argue that it is counterexampled by a certain kind of Gettier case where the fact that p is a cause of the subject’s belief that p. One can φ for the reason that p even if one does not know that p. So knowledge (...) is not best conceived as an ability of this kind. (shrink)

This paper details the ways that gender structures our senses of agency on an enactive framework. While it is common to discuss how gender influences higher, narrative levels of cognition, as with the formulation of goals and in considerations about our identities, it is less clear how gender structures our more immediate, embodied processes, such as the minimal sense of agency. While enactivists often acknowledge that gender and other aspects of our socio-cultural situatedness shape our cognitive processes, there is little (...) work on how this shaping takes place. In order to provide such an account, I will first look at the minimal and narrative senses of agency (Gallagher 2012), a distinction that draws from work on minimal and narrative selves (Zahavi 2010). Next I will explain the influence of the narrative sense of agency on the minimal sense of agency through work on intention-formation (Pacherie 2007). After a discussion of the role of gender in the narrative sense of agency, I’ll expand on work by Haslanger (2012) and Young (1980) to offer three ways in which gender influences the minimal sense of agency, showing the effect that gender has on how we perceive our possibilities for interaction in a phenomenologically immediate, pre-reflective manner.

The notion of more truth, or of more truth and less falsehood, is central to epistemology. Yet, I argue, we have no idea what this consists in, as the most natural or obvious thing to say—that more truth is a matter of a greater number of truths, and less falsehood is a matter of a lesser number of falsehoods—is ultimately implausible. The issue is important not merely because the notion of more truth and less falsehood is central to epistemology, but (...) because an implicit, false picture of what this consists in underpins and gives shape to much contemporary epistemology.

I reply to Andrea Baldini's critical discussion of my "Street Art: The Transfiguration of the Commonplaces" (2010) by taking up the question: what is "the street" in street art? I argue that the relevant notion of the street is a space whose function it is to facilitate self-expression. I show how this clarifies and extends the theory developed in Riggle (2010). I then argue, contra Baldini, that street art is not always subversive, and when it is, it is not always (...) in virtue of its challenging the co-opting of public space by commercial art. (shrink)

How sexuality should be regulated in a liberal political community is an important, controversial theoretical and empirical question—as shown by the recent criminalization of possession of some adult pornography in the United Kingdom. Supporters of criminalization argue that Mill, often considered a staunch opponent of censorship, would support prohibition due to his feminist commitments. I argue that this account underestimates the strengths of the Millian account of private conduct and free expression, and the consistency of Millian anticensorship with feminist values. (...) A Millian contextual defense of liberty, however, suggests several other policy approaches to addressing the harms of pornography. (shrink)

We address the problem of predicting how people will spontaneously divide into groups a set of novel items. This is a process akin to perceptual organization. We therefore employ the simplicity principle from perceptual organization to propose a simplicity model of unconstrained spontaneous grouping. The simplicity model predicts that people would prefer the categories for a set of novel items that provide the simplest encoding of these items. Classification predictions are derived from the model without information either about the number (...) of categories sought or information about the distributional properties of the objects to be classified. These features of the simplicity model distinguish it from other models in unsupervised categorization (where, for example, the number of categories sought is determined via a free parameter), and we discuss how these computational differences are related to differences in modeling objectives. The predictions of the simplicity model are validated in four experiments. We also discuss the significance of simplicity in cognitive modeling more generally. (shrink)
