Previous research has successfully used feature integration theory to operationalise the predictions of Perceptual Load Theory, while simultaneously testing the predictions of both models. Building on this work, we test the extent to which these models hold up in a 3D world. In two experiments, participants responded to a target stimulus within an array of shapes whose apparent depth was manipulated using a combination of monoscopic and stereoscopic cues. The search task was designed to test the predictions of feature integration (...) theory, as the target was identified by a single feature or a conjunction of features and embedded in search arrays of varying size, and perceptual load theory, as the task included congruent and incongruent distractors presented alongside search tasks imposing high or low perceptual load. Findings from both experiments upheld the predictions of feature integration theory, regardless of 2D/3D condition. Longer search times in conditions with a combination of monoscopic and stereoscopic depth cues suggests that binding features into three-dimensional objects requires greater attentional effort. This additional effort should have implications for perceptual load theory, yet our findings did not uphold its predictions; the effect of incongruent distractors did not differ between conjunction search trials and feature search trials. Individual differences in susceptibility to the effects of perceptual load were evident and likely explain the absence of load effects. Overall, our findings suggest that feature integration theory may be useful for predicting attentional performance in a 3D world. (shrink)

This collection presents significant contributions from an international network project on mathematical cultures, including essays from leading scholars in the history and philosophy of mathematics and mathematics education.​ Mathematics has universal standards of validity. Nevertheless, there are local styles in mathematical research and teaching, and great variation in the place of mathematics in the larger cultures that mathematical practitioners belong to. The reflections on mathematical cultures collected in this book are of interest to mathematicians, philosophers, historians, sociologists, cognitive scientists and (...) mathematics educators.

What accounts for the capacity of ordinary speakers to comprehend utterances of their language? The phenomenology of hearing speech in one’s own language makes it tempting to many epistemologists to look to perception for an answer to this question. That is, just as a visual experience as of a red square is often taken to give the perceiver immediate justification for believing that there is a red square in front of her, perhaps an auditory experience as of the speaker asserting (...) that p gives the competent hearer immediate justification for believing that the speaker has asserted that p. My aim here is to offer reasons for resisting this temptation. I argue that the perceptual model cannot adequately account for the hearer’s justification in many cases. The arguments here also allow us to draw certain further morals about the role of phenomenology in the epistemology of perception. (shrink)

Current debates in science and technology studies emphasize that the bio-economy—or, the articulation of capitalism and biotechnology—is built on notions of commodity production, commodification, and materiality, emphasizing that it is possible to derive value from body parts, molecular and cellular tissues, biological processes, and so on. What is missing from these perspectives, however, is consideration of the political-economic actors, knowledges, and practices involved in the creation and management of value. As part of a rethinking of value in the bio-economy, this (...) article analyzes three key political-economic processes: financialization, capitalization, and assetization. In doing so, it argues that value is managed as part of a series of valuation practices, it is not inherent in biological materialities. (shrink)

English mass noun phrases & count noun phrases differ only minimally grammatically. The basis for the difference is ascribed to a difference in the features +/-CT. These features serve the morphosyntactic function of determining the available options for the assigment of grammatical number, itself determined by the features +/-PL: +CT places no restriction on the available options, while -CT, in the unmarked case, restricts the available options to -PL. They also serve the semantic function of determining the sort of denotation (...) associated with demonstrative & quantified noun phrases. The feature -CT requires that the associated denotation be the set whose sole member is the greatest aggregate of which the noun phrase or noun is true; the feature +CT requires that the associated denotation be the set whose members are all & only those minimal aggregates of which the noun phrase or noun is true. At the same time, neither mass NPs nor count NPs that are arguments of a predicate have their predicate evaluated with respect to their denotations. Rather, the predicate is evaluated with respect to an aggregation, a set of aggregates constructed from the denotation of the noun phrase that is an argument of the predicate. 3 Tables, 4 Figures, 74 References.

Contemporary, technoscientific capitalism is characterized by the configuration of a range of “things” as assets or capitalized property. Accumulation strategies have changed as a result of this assetization process. Rather than entrepreneurial strategies based on commodity production, technoscientific capitalism is increasingly underpinned by rentiership or the appropriation of value through ownership and control rights, monopoly conditions, and regulatory or market devices and practices. While rentiership is often presented as a negative phenomenon in both neoclassical and Marxist political economy literatures—and much (...) in between—in this paper, I conceptualize rentiership as a technoeconomic practice and process framed by insights from science and technology studies. So, rather than a problematic “side effect” of capitalism, the concept of rentiership enables us to understand how different forms of value extraction constitute, and are constituted by, different forms of technoscience. This allows STS to contribute a distinctive analytical approach to ongoing debates in political economy about economic rents and rent-seeking. (shrink)

The United States Supreme Court recently ruled that execution by a commonly used protocol of drug administration does not represent cruel or unusual punishment. Various medical journals have editorialized on this drug protocol, the death penalty in general and the role that physicians play. Many physicians, and societies of physicians, express the opinion that it is unethical for doctors to participate in executions. This Target Article explores the harm that occurs to murder victims' relatives when an execution is delayed or (...) indefinitely postponed. By using established principles in psychiatry and the science of the brain, it is shown that victims' relatives can suffer brain damage when justice is not done. Conversely, adequate justice can reverse some of those changes in the brain. Thus, physician opposition to capital punishment may be contributing to significant harm. In this context, the ethics of physician involvement in lethal injection is complex. (shrink)

Purcell, Brendan The Focolare Movement is officially known as the Work of Mary, and since it is primarily a lay movement, it falls under the authority of the Congregation for the Laity. Its founder, Chiara Lubich, was born in Trent in 1920, the second of four children, into a close-knit family. Her mother was a devout daily Massgoing Catholic, her father, a socialist, uninterested in religion, but a man of principle, whose refusal to join the Fascist party lost him (...) any chance of a regular job after the 1929 Depression.

As modern viewers, it is tempting to interpret Frank and Claire’s manipulations of democratic institutions as representing perversions or distortions of democratic ideals. After all, most of us think (or at least hope!) that real-world democracies we actually live in aren’t quite that badly governed. Whatever the moral faults of our leaders are, they don’t (as a rule) murder journalists, crudely provoke international crises for political gain, or cleverly set up their political adversaries with Bond-villain-like cunning. Real politicians, so the (...) story goes, lack the cleverness, the ruthlessness, and the luck of the Underwoods. While this sort of faith in the general validity of democratic ideals and institutions is now widely shared, the Underwoods’ clever “gaming” of the system can also be seen as providing an especially clear illustration of some of the things that might be inherently wrong with democracy. In this essay, I’ll take a look at how the Underwoods’ behavior might look to some of the most famous critics of democratic government, including Plato, Thomas Hobbes, and Karl Marx. According to these thinkers, the most significant flaws that Underwoods exploit to gain political power have little, if anything, to do with the peculiarity of their talents, the weaknesses of the individuals around them, or even the structures of the US political system. Instead, their success is made possible by certain fundamental features of democratic government, features that guarantee both the instability and eventual failure of any democratic government. On this reading, the fact of the Underwoods’ success presents a significant problem for all of us, since it changes the question from “How do real-world democratic politicians differ from the Underwoods?” to the much-more-difficult “What’s so great about democracy in the first place?”.

ABSTRACTIn 2001, Julian Savulescu wrote an article entitled ‘Procreative Beneficence: Why We Should Select the Best Children’, in which he argued for the genetic selection of intelligence in children. That article contributes to a debate on whether genetic research on intelligence should be undertaken at all and, if so, should intelligence selection be available to potential parents. As such, the question of intelligence selection relates to wider issues concerning the genetic determination of behavioural traits, i.e. alcoholism. This article is designed (...) as an engagement in the intelligence selection debate using an analysis of Savulescu's arguments to raise a series of problematic issues in relation to the ethics of parental selection of intelligence. These problematic issues relate to wider assumptions that are made in order to put forward intelligence selection as a viable ethical option. Such assumptions are more generic in character, but still relate to Savulescu's article, concerning issues of genetic determinism, private allocation and inequality, and, finally, individual versus aggregate justice. The conclusion focuses on what the implications are for the question of agency, especially if intelligence selection is allowed. (shrink)

In bioethics there is an ongoing debate about the ethical case for human enhancement through new biomedical technologies. In this debate there are both supporters and opponents of human enhancement technologies such as genetic improvements of cognitive abilities (eg, intelligence). The supporters argue that human enhancement will lead to healthier and therefore better lives, meaning that any delays to the introduction of such technologies is problematic. In contrast, the opponents argue that new technologies will not solve problems such as inequality (...) and social justice. In order to overcome opposition to human enhancement, Bostrom and Ord have outlined a test to evaluate ethical arguments for "status quo bias" or what they call "intuitive judgements" in the assessment of human enhancement. This article is a response to their paper in which I raise a number of problems with their position, particularly with their "status quo bias" test and the incorporation of economistic thinking into their ethical arguments.

Religious congregations of women have been socialized in a tradition rich in gospel values, but one which was also hierarchical and patriarchal. My own congregation, the Little Company of Mary, is an international one, involved in health care since our foundation in Victorian England. Within both spheres, religious and medical, the patriarchal influence was strong and uncritically accepted until the second half of the twentieth cen tury. Here, I attempt to bring feminist and nursing philosophy to bear on the care (...) debate within nursing. An ethic of care demands that we go beyond competence, important as that is. This ethic, found to be at the heart of our LCM identity, suggests to us today, that our founder, Mary Potter was a feminist ahead of her time. (shrink)

There is growing agreement among scholars and citizens that our planet and its peoples are presently living through an era of great political uncertainty. Global pestilence, species destruction, shrinking US power and the birth of a new Chinese global empire are among the forces said to be responsible for the rising tides of uncertainty. Some observers even speak of a great leap backwards, a regression towards catastrophe, a rebirth of the disquiet and fear that marked the world of the 1920s (...) and 1930s. They are sure that the future will bring only threats, rather than new opportunities to live well. This essay notes the seriousness of things, but it raises doubts about these pessimistic claims of a new age of uncertainty. Historical comparisons are needed. So is greater clarity about the role played by communicative abundance in inflating our collective sense of doom. And a paradox is noted: calamities do more than stir up questions about how best to classify and measure the experience of uncertainty. Definitions of uncertainty also become uncertain. This should be unsurprising. Only institutions and everyday experiences unaffected by the flow of time could be defined and lived with any certainty. The insight not only has rich implications for the way we think about politics and democracy and its vulnerability to morbid backlashes and yearnings for demagogues. Doubt can generate fresh ideas and positive practical breakthroughs. Disquiet and incertitude are fickle characters, but they are also challengers of all forms of human arrogance, including the dogmatic conviction that our world is now headed for hell. (shrink)

According to current hierarchies of evidence for EBM, evidence of correlation (e.g., from RCTs) is always more important than evidence of mechanisms when evaluating and establishing causal claims. We argue that evidence of mechanisms needs to be treated alongside evidence of correlation. This is for three reasons. First, correlation is always a fallible indicator of causation, subject in particular to the problem of confounding; evidence of mechanisms can in some cases be more important than evidence of correlation when assessing a (...) causal claim. Second, evidence of mechanisms is often required in order to obtain evidence of correlation (for example, in order to set up and evaluate RCTs). Third, evidence of mechanisms is often required in order to generalise and apply causal claims. While the EBM movement has been enormously successful in making explicit and critically examining one aspect of our evidential practice, i.e., evidence of correlation, we wish to extend this line of work to make explicit and critically examine a second aspect of our evidential practices: evidence of mechanisms.

These days it is widely agreed that there is no such thing as absolute motion and rest; the motion of an object can only be characterized with respect to some chosen frame of reference.1 This is a fact of which many of us are well-aware, and yet a cursory consideration of the ways we ascribe motion to objects gives the impression that it is a fact we persistently ignore. We insist to the police officer that we came to a full (...) and complete stop at the stop sign, we fret that traffic is moving too slowly, we observe that the sun has dropped below the hills on the horizon, all without ever saying which frames of reference we have in mind.

In this provocative book, John Keane calls for a fresh understanding of the vexed relationship between democracy and violence. Taking issue with the common sense view that 'human nature' is violent, Keane shows why mature democracies do not wage war upon each other, and why they are unusually sensitive to violence. He argues that we need to think more discriminatingly about the origins of violence, its consequences, its uses and remedies. He probes the disputed meanings of the term (...) violence, and asks why violence is the greatest enemy of democracy, and why today's global 'triangle of violence' is tempting politicians to invoke undemocratic emergency powers. Throughout, Keane gives prominence to ethical questions, such as the circumstances in which violence can be justified, and argues that violent behaviour and means of violence can and should be 'democratised' - made publicly accountable to others, so encouraging efforts to erase surplus violence from the world.

Uttered language does not necessarily reflect the planned communications of schizophrenia patients, nor do their delusions necessarily reflect basic failures of inferential reasoning. The role of inhibitory failure in the production of speech and the role of primary experiences of discrepancy between intention and action, and between experience–based expectations and perceived realities account for many of the clinical phenomena that have led to the conclusion that these patients have a ‘thought’ disorder, or a ‘disturbed’ mind. The alternatives and the evidence (...) are summarized in this paper. (shrink)

The collection of very large text sources has revolutionized the study of natural language, leading to the development of several models of language learning and distributional semantics that extract sophisticated semantic representations of words based on the statistical redundancies contained within natural language. The models treat knowledge as an interaction of processing mechanisms and the structure of language experience. But language experience is often treated agnostically. We report a distributional semantic analysis that shows written language in fiction books varies appreciably (...) between books from the different genres, books from the same genre, and even books written by the same author. Given that current theories assume that word knowledge reflects an interaction between processing mechanisms and the language environment, the analysis shows the need for the field to engage in a more deliberate consideration and curation of the corpora used in computational studies of natural language processing.

Notice that each of (1)–(4) is an instance of a more general pattern. For example, we could replace ‘black’ in (1) with any of a wide range of other adjectives such as ‘furry’ or ‘hungry’ or ‘three-legged’, without rendering the entailment invalid or any less obvious. Similarly, there are a number of verbs that occur in entailments parallel to (3): ‘Moe boiled the water; so the water boiled’; ‘Bart blew up the school; so the school blew up’; ‘Homer sank the (...) boat; so the boat sank’ and so on.

Mechanistic philosophy of science views a large part of scientific activity as engaged in modelling mechanisms. While science textbooks tend to offer qualitative models of mechanisms, there is increasing demand for models from which one can draw quantitative predictions and explanations. Casini et al. (Theoria 26(1):5–33, 2011) put forward the Recursive Bayesian Networks (RBN) formalism as well suited to this end. The RBN formalism is an extension of the standard Bayesian net formalism, an extension that allows for modelling the hierarchical (...) nature of mechanisms. Like the standard Bayesian net formalism, it models causal relationships using directed acyclic graphs. Given this appeal to acyclicity, causal cycles pose a prima facie problem for the RBN approach. This paper argues that the problem is a significant one given the ubiquity of causal cycles in mechanisms, but that the problem can be solved by combining two sorts of solution strategy in a judicious way.

The human propensity to take an ethical stance toward oneself and others is found in every known society, yet we also know that values taken for granted in one society can contradict those in another. Does ethical life arise from human nature itself? Is it a universal human trait? Or is it a product of one's cultural and historical context? Webb Keane offers a new approach to the empirical study of ethical life that reconciles these questions, showing how ethics (...) arise at the intersection of human biology and social dynamics. Drawing on the latest findings in psychology, conversational interaction, ethnography, and history, Ethical Life takes readers from inner city America to Samoa and the Inuit Arctic to reveal how we are creatures of our biology as well as our history--and how our ethical lives are contingent on both. Keane looks at Melanesian theories of mind and the training of Buddhist monks, and discusses important social causes such as the British abolitionist movement and American feminism. He explores how styles of child rearing, notions of the person, and moral codes in different communities elaborate on certain basic human tendencies while suppressing or ignoring others."--Publisher's Web site.

This paper argues that promises are proposals in joint practical deliberation, the activity of deciding together what to do. More precisely: to promise to ϕ is to propose (in a particular way) to decide together with your addressee(s) that you will ϕ. I defend this deliberative theory by showing that the activity of joint practical deliberation naturally gives rise to a speech act with exactly the same properties as promises. A certain kind of proposal to make a joint decision regarding (...) one's own actions turns out to have the very same normative effects, under the very same conditions, as a promise. I submit that this cannot be a coincidence: we should conclude that promises and the relevant kind of proposals in joint practical deliberation are one and the same. (shrink)

One way to challenge the substantiveness of a particular philosophical issue is to argue that those who debate the issue are engaged in a merely verbal dispute. For example, it has been maintained that the apparent disagreement over the mind/brain identity thesis is a merely verbal dispute, and thus that there is no substantive question of whether or not mental properties are identical to neurological properties. The goal of this paper is to help clarify the relationship between mere verbalness and (...) substantiveness. I first argue that we should see mere verbalness as a certain kind of discourse defect that arises when the parties differ as to what each takes to be the immediate question under discussion. I then argue that mere verbalness, so understood, does not imply that the question either party is attempting to address is a non-substantive one. Even if it turns out that the parties to the mind/brain dispute are addressing subtly different questions, these might both be substantive questions to which their respective metaphysical views provide substantive answers. One reason it is tempting to reach deflationary conclusions from the charge of mere verbalness is that we fail to distinguish it from the claim that a sentence under dispute is, in a certain sense, indisputable. Another reason is that we fail to distinguish mere verbalness from a certain sort of indeterminacy. While indisputability and indeterminacy plausibly capture forms of nonsubstantiveness, I argue that mere verbalness is insufficient to establish either indisputability or indeterminacy. (shrink)

Alaska s Aleutian Island chain, barren and windswept, arcs for over a thousand miles toward Asia from the Alaska Peninsula. In this remote and hostile archipelago is Kiska, an uninhabited sub-arctic speck in the tempestuous Bering Sea. Few have the opportunity even to visit this island, but in June of 1942 Japanese troops seized Kiska and neighboring Attu in the only occupation of North American territory since the War of 1812. The bastion of Japan s possessions in Alaska, Kiska was (...) soon fortified with 7,500 enemy troops, a seaplane base, naval anchorage and submarine base, heavy guns and a labyrinth of tunnels. For thirteen months Japanese troops held a tenuous hold on the island under constant bombardment from American forces, but finally and successfully abandoning the island. So hurried was the evacuation that equipment and personal effects were left behind. The Japanese occupiers of Kiska have remained shadowy figures. Brendan Coyle spent 51 days on Kiska searching out the tunnels, equipment and personal effects frozen in time. Those objects are brought back to life in the over three hundred images Coyle has assembled from his own visit and from archives. His writing puts the images in historical and contemporary perspective, opening a new window on a remote battlefield and unforgiving landscape.". (shrink)

Evidence-based medicine (EBM) makes use of explicit procedures for grading evidence for causal claims. Normally, these procedures categorise evidence of correlation produced by statistical trials as better evidence for a causal claim than evidence of mechanisms produced by other methods. We argue, in contrast, that evidence of mechanisms needs to be viewed as complementary to, rather than inferior to, evidence of correlation. In this paper we first set out the case for treating evidence of mechanisms alongside evidence of correlation in (...) explicit protocols for evaluating evidence. Next we provide case studies which exemplify the ways in which evidence of mechanisms complements evidence of correlation in practice. Finally, we put forward some general considerations as to how the two sorts of evidence can be more closely integrated by EBM. (shrink)

The plays in this new volume were written early in Marcel’s career, and were published together under the title Le Seuil invisible (The Invisible Threshold) in 1913. The first play, Grace, explores the theme of religious conversion. The drama depicts a crisis between characters of genuine depth and sincerity, who are struggling with different interpretations of shared experiences. Similar themes are addressed but developed differently in the second play, The Sandcastle. This drama explores the confrontation between one’s beliefs and their (...) consequences when faced with challenging family and social circumstances. The play asks us to think about what happens when our beliefs and theories, especially about religion, morality and politics, come up against situations in life that can test them. Both plays illustrate one of the major themes of both Marcel’s dramatic and philosophical work: that life’s most profound, fulfilling experiences are compromised more than ever in what he describes as the modern, broken world (le monde cassé), one unfortunately characterized by alienation, loss of meaning and feelings of despair.

Simone de Beauvoir's novel She Came to Stay follows Françoise and her partner Pierre as their intimacy becomes increasingly entangled with the young and tempestuous Xavière. Many readings of the novel explain Françoise's bad feeling and eventual violence as symptoms of sexual jealousy. The book has also been read as a veiled autobiography of Beauvoir and Sartre's similar entanglement with Olga Kosakiewicz, so that, very often, Françoise's jealousy is assumed to stand in for Beauvoir's own. This article is about misreading (...) in two ways. First, I argue that the common view that this is a story in part or in whole about sexual jealousy reflects a radical simplification of the emotional and interpersonal dynamics of the “trio.” Second, I argue that this interpretive simplification is in fact common in mainstream readings of nonmonogamous relationships, where “jealousy” is used to name any and all bad feelings in the vicinity of the nonmonogamous relationship, and where that bad feeling is interpreted as caused by the nonmonogamy itself. To conclude, I suggest that She Came to Stay, and particularly its notorious ending, can be seen as Beauvoir's depiction—and refusal—of the misreadings that constitute the “situation” of nonmonogamy in everyday life.

This chapter looks at the genesis of Heidegger’s reflections on affect, embodied speaking together, the nature of possibility and the critique of actuality, which form the soil in which the later existential analysis of Being and Time sinks its roots. These original reflections are to be found in the 1924 summer semester lecture course entitled Basic Concepts of Aristotelian Philosophy. On the basis of this, the chapter shows how the early lectures help us understand what happens to Heidegger’s reflections on (...) affect, dynamis, and being together with others, shaping the development of his later critique of the metaphysics of actuality in both Being and Time and in the Contributions to Philosophy.
