The article first discusses the presence among Christians in Roman Africa of "biblical" writings that are not found in the current canon of Scripture. This is followed by a review of what is known of the Manichaean use of extra-canonical material in general, particularly within the Roman Empire, and especially of the pseudepigraphical Acts of the Apostles. Finally, the article focuses on the use among Manichaeans in Roman Africa of this pseudepigraphic literature, especially the Acts of the Apostles. In all (...) cases, the article focuses on cases of a confirmed pseudepigraphic presence, rather than on mere conjectures about it. (shrink)

Predictable polarization is everywhere: we can often predict how people’s opinions, including our own, will shift over time. Extant theories either neglect the fact that we can predict our own polarization, or explain it through irrational mechanisms. They needn’t. Empirical studies suggest that polarization is predictable when evidence is ambiguous, that is, when the rational response is not obvious. I show how Bayesians should model such ambiguity and then prove that—assuming rational updates are those which obey the value of evidence—ambiguity (...) is necessary and sufficient for the rationality of predictable polarization. The main theoretical result is that there can be a series of such updates, each of which is individually expected to make you more accurate, but which together will predictably polarize you. Polarization results from asymmetric increases in accuracy. This mechanism is not only theoretically possible, but empirically plausible. I argue that cognitive search—searching a cognitively accessible space for a particular item—often yields asymmetrically ambiguous evidence, I present an experiment supporting its polarizing effects, and I use simulations to show how it can explain two of the core causes of polarization: confirmation bias and the group polarization effect.

Philosophers and linguists currently lack the means to reliably identify evaluative concepts and measure their evaluative intensity. Using a corpus-based approach, we present a new method to distinguish evaluatively thick and thin adjectives like ‘courageous’ and ‘awful’ from descriptive adjectives like ‘narrow,’ and from value-associated adjectives like ‘sunny.’ Our study suggests that the modifiers ‘truly’ and ‘really’ frequently highlight the evaluative dimension of thick and thin adjectives, allowing for them to be uniquely classified. Based on these results, we believe our (...) operationalization may pave the way for a more quantitative approach to the study of thick and thin concepts. (shrink)

It is commonly assumed that images, whether in the world or in the head, do not have a privileged analysis into constituent parts. They are thought to lack the sort of syntactic structure necessary for representing complex contents and entering into sophisticated patterns of inference. I reject this assumption. “Image grammars” are models in computer vision that articulate systematic principles governing the form and content of images. These models are empirically credible and can be construed as literal grammars for images. (...) Images can have rich syntactic structure, though of a markedly different form than sentences in language. (shrink)

According to H.L.A. Hart's analysis, to utter an internal legal statement is partly to express an acceptance of a set of norms. This article attempts to defend Hart's conception of internal legal discourse by responding to the following three lines of criticism that can be found in Joseph Raz's writings: (i) that Hart's analysis fails to account for what Raz calls ‘detached legal statements’; (ii) that Hart's deployment of the notion of acceptance in his analysis vitiates his legal positivist project (...) because such acceptance necessarily amounts to moral endorsement; and (iii) that Hart is wrong to assume that normative practices, including discursive legal practices, can be characterized satisfactorily by deploying only descriptive statements. I argue that Hart's theory, or at least a theory along the lines that Hart developed, has sufficient resources to handle satisfactorily these criticisms. His world is a noonday world in which sharply outlined figures, most of them more than a little singular, act in describable ways against perceptible backgrounds.

The gambler’s fallacy is the tendency to expect random processes to switch more often than they actually do—for example, to think that after a string of tails, a heads is more likely. It’s often taken to be evidence for irrationality. It isn’t. Rather, it’s to be expected from a group of Bayesians who begin with causal uncertainty, and then observe unbiased data from an (in fact) statistically independent process. Although they converge toward the truth, they do so in an asymmetric (...) way—ruling out “streaky” hypotheses more quickly than “switchy” ones. As a result, the majority (and the average) exhibit the gambler’s fallacy. If they have limited memory, this tendency persists even with arbitrarily-large amounts of data. Indeed, such Bayesians exhibit a variety of the empirical trends found in studies of the gambler’s fallacy: they expect switches after short streaks but continuations after long ones; these nonlinear expectations vary with their familiarity with the causal system; their predictions depend on the sequence they’ve just seen; they produce sequences that are too switchy; and they exhibit greater rates of gambler’s reasoning when forming binary predictions than when forming probability estimates. In short: what’s been thought to be evidence for irrationality may instead be rational responses to limited data and memory. (shrink)

In this chapter, Macnish and Asgarinia introduce current thinking and debate around issues of privacy as these relate to the media. Starting with controversies over the definition of privacy, they consider what the content of privacy should be and why it is we consider privacy to be valuable. This latter includes the social implications of privacy and the only recently-recognised concept of group privacy, contrasting it with individual privacy, as well as legal implications arising through laws such as the European (...) Union’s General Data Protection Regulation, concerning the collection of personal data and data subjects’ rights. Finally they turn to specific instances of privacy consideration in the media. These include: -/- The use of telephoto lenses to take pictures of celebrities at a distance without those celebrities’ permission (and the related question as to what is a reasonable expectation of privacy when in a public place); -/- Sharing information on social media (and the related question of whether those who share their data on social networking sites care about their privacy), as well as the availability of data online to research, even though that data has not always been posted for the purposes of research; -/- The challenges posed by anonymity online, including the trade-off between free expression and offensive expression; -/- Hacking and the meaning of fishing expeditions as a practice by the media and exploring what, if anything, is wrong with these; -/- The implications of invading the privacy of politicians, both as a defence of democracy and as a threat to democracy.

The idea of moral responsibility is central to a wide range of our moral, social, and legal practices, and it underpins our basic notion of culpability. Yet the idea of moral responsibility is increasingly viewed with skepticism by researchers and scholars in psychology, neuroscience, philosophy, and the law. Building Better Beings: A Theory of Moral Responsibility responds to these challenges, offering a new account of the justification of our practices and judgments of moral responsibility. Three distinctive ideas shape the account. (...) The first is the agency cultivation model, which holds that a system of responsibility practices can derive its justification from the way it supports our agency. The second idea, circumstantialism, is a new way of thinking about agential capacities. This is the view that the capacities required for moral responsibility are functions of agents in circumstances, rather than basic features of agents considered in themselves. The third idea is revisionism, or the idea that a satisfactory theory of moral responsibility will conflict with some aspects of ordinary commitments about freedom and moral responsibility. (shrink)

A series of imitation games involving 3-participant (simultaneous comparison of two hidden entities) and 2-participant (direct interrogation of a hidden entity) were conducted at Bletchley Park on the 100th anniversary of Alan Turing’s birth: 23 June 2012. From the ongoing analysis of over 150 games involving (expert and non-expert, males and females, adults and child) judges, machines and hidden humans (foils for the machines), we present six particular conversations that took place between human judges and a hidden entity that produced (...) unexpected results. From this sample we focus on features of Turing’s machine intelligence test that the mathematician/code breaker did not consider in his examination for machine thinking: the subjective nature of attributing intelligence to another mind.

This paper seeks to uncover and rationally reconstruct four theoretical prescriptions that H. L. A. Hart urged philosophers to observe and follow when investigating and theorizing about the nature of law. The four prescriptions may appear meager and insignificant when each is seen in isolation, but together as an inter-connected set they have substantial implications. In effect, they constitute a central part of Hart's campaign to put philosophical investigations about the nature of law onto a path to a genuine research (...) program. The paper takes note of certain prevalent and robust trends in contemporary legal philosophy that detract its practitioners from the four prescriptions, and that have them revert to the some older modes of thinking from which Hart sought a decisive break. A number of contemporary legal philosophers' views and commitments are taken up and assessed, and in particular those of John Gardner and Leslie Green. ‘Yet the answer is a prosaic one: don’t ask what time is but how the word ‘time’ is being used’.Friedrich Waismann.I miss the future.Jaron Lanier.

Experimental philosophy of consciousness aims to investigate and explain our thinking about phenomenally conscious states. Based on empirical studies, researchers have argued (a) that we lack a folk concept of consciousness, (b) that we do not think entities like Microsoft feel regret, (c) that unfelt pains are widely accepted, and (d) that people do not attribute phenomenally conscious states to duplicated hamsters. In this article, I review these and other intriguing claims about people’s understanding of phenomenal consciousness. In doing so, (...) I also show why experimental philosophy of consciousness is challenging, although perhaps not quite as daunting as studying phenomenal consciousness itself. (shrink)

Explanation and evidence are related in one way that is uncontroversial: evidence can confirm or disconfirm explanations. One explanation of Sally’s cold is that she has a virus; another is that she has a bacterial infection. The available evidence confirms the virus explanation because the evidence supports that colds are caused by viruses, not bacteria. A more interesting question concerns whether explanatory facts themselves provide evidence. That is to say, do we get evidence for p simply by realizing that p, (...) if true, would explain some data? Explanationists answer this question affirmatively, maintaining that explanatoriness is evidence of truth. (shrink)

In his recent The Parmenidean Ascent, Michael Della Rocca develops a regress-theoretic case, reminiscent of F.H. Bradley’s famous argument in Appearance and Reality, against the intelligibility of relations and in favor of a monistic conception of reality. I argue that Della Rocca illicitly supposes that “internal” relations – in one sense of that word – lead to a “chain” regress, a regress of relations relating relations and relata. In contrast, I contend that if “internal” or grounded relations lead to a (...) regress at all, it is a kind of “fission” regress within the relata themselves, and that a chain regress for relations only arises, if at all, for so-called “external” relations, relations not grounded in their relata. In this way, I contend that Della Rocca pursues a regress for so-called “internal” or grounded relations that only arises, if at all, for so-called “external” relations, relations not grounded in their relata. I compare Della Rocca’s case against relations with Bradley’s reasoning in Appearance and Reality, and suggest in this context that Bradley may, perhaps, have the upper hand. (shrink)

Preference, according to many theories of human behaviour, is a very important phenomenon. It is therefore some what surprising that philosophers of mind pay so little attention to it. One question about preference concerns its variety. Is preference always preference for one option or state of affairs rather than another? Or is there also, as ordinary language suggests, object-preference – preferences for one person rather than another, for one country rather than another, for one value rather than another? Another question (...) or rather group of questions concerns the nature of preference. Is it a mental state, disposition, act or episode, a theoretical construct, a purely behavioural phenomenon? If it is a mental state or act, is it an intellectual, affective or a conative phenomenon? If it is an affective phenomenon, does it enjoy a positive or negative “valence”? Is preference to be understood as a relation between a person’s attitudes or is it a primitive phenomenon? (shrink)

This volume presents 15 studies occasioned by the 500th anniversary of the European discovery of America. It covers both the initial encounters between the Europeans and native Americans and the golden age of Hispanic philosophy that followed the discovery - specifically between 1500 and 1650.

Elaine Scarry argues in The Body in Pain that war is a vast and reciprocal swearing on the body, with corporeality key not only to its brutal prosecution but also to the eventual ending of the political ‘crisis of substantiation’ that war entails. However, her work has not been extensively explored with reference to significant transformations in the embodied experiences of contemporary warfare. This article thus analyses a particular articulation of late modern warfare that I term predatory war, whose current (...) signature motif is the drone strike, through the lens of Scarry’s work. Here, the associated modes of embodiment are radically non-reciprocal, the woundscapes of conflict are profoundly asymmetric, and the affective mediation of bodily injury does not substantiate any ending to the conflict. As such, I argue that the ontology and phenomenology of predatory war increasingly resembles what Scarry identifies as the underlying structure of torture. (shrink)

Was David Hume radically sceptical about our attempts to understand the world or was he merely approaching philosophical problems from a scientific perspective? Most philosophers today believe that Hume's outlook was more scientific than radically sceptical and that his scepticism was more limited than previously supposed. If these philosophers are correct, then Hume's approach to philosophy mirrors the approach of many contemporary philosophers. This similarity between Hume and many aspects of contemporary philosophy suggests that we should try to understand Hume (...) not as an historical relic but as a partner in a continuing philosophical dialogue. When we look closely at Hume's thoughts about human understanding, we find that Hume's scepticism emerges very insistently in the context of Hume's scientific approach. This book tries to come to terms with Hume's scepticism in a way that sheds light on contemporary philosophy and its relationship to science. (shrink)

According to a widely held view, people's commitments to laws are dependent on the existence in their community of a conventional practice of complying with certain fundamental laws. This conventionalism has significantly hampered our attempts to explain the normative practice of law. Ronald Dworkin has argued against conventionalism by bringing up the phenomenon of persistent fundamental legal controversies, but neither Dworkin nor his legal positivist respondents have correctly understood the real significance of such controversies. This article argues that such controversies (...) pose a deep challenge to any conception of our legal practice as a genuinely normative, rule-mediated, practice. The article also argues that what is needed to deflect this challenge is a new understanding – different from the widely held conventionalist understanding – of how people's commitments to laws are predicated on their fellows’ like commitments.

According to reductionists about agency, an agent’s bringing something about is reducible to states and events involving the agent bringing something about. Many have worried that reductionism cannot accommodate robust forms of agency, such as self-determination. One common reductionist answer to this worry contends that self-determining agents are identified with certain states and events, and so these states and events causing a decision counts as the agent’s self-determining the decision. In this paper I discuss J. David Velleman’s identification reductionist theory, (...) according to which an agent is identified with his desire to make most sense of himself. I develop two constraints that an adequate identification reductionist theory must satisfy and show that Velleman’s theory cannot satisfy both. In particular, I argue that Velleman’s account founders on cases of self-determined self-transformation. (shrink)

Wittgenstein was centrally concerned with the puzzling nature of the mind, mathematics, morality and modality. He also developed innovative views about the status and methodology of philosophy and was explicitly opposed to crudely "scientistic" worldviews. His later thought has thus often been understood as elaborating a nuanced form of naturalism appealing to such notions as "form of life", "primitive reactions", "natural history", "general facts of nature" and "common behaviour of mankind". And yet, Wittgenstein is strangely absent from much of the (...) contemporary literature on naturalism and naturalising projects. This is the first collection of essays to focus explicitly on the relationship between Wittgenstein and naturalism. The volume is divided into four sections, each of which addresses a different aspect of naturalism and its relation to Wittgenstein's thought. The first section considers how naturalism could or should be understood. The second section deals with some of the main problematic domains—consciousness, meaning, mathematics—that philosophers have typically sought to naturalise. The third section explores ways in which the conceptual nature of human life might be continuous in important respects with animals. The final section is concerned with the naturalistic status and methodology of philosophy itself. This book thus casts a fresh light on many classical philosophical issues and brings Wittgensteinian ideas to bear on a number of current debates-for example experimental philosophy, neo-pragmatism and animal cognition/ethics-in which naturalism is playing a central role.
