As imaging technologies help us understand the structure and function of the brain, providing insight into human capabilities as basic as vision and as complex as memory, and human conditions as impairing as depression and as fraught as psychopathy, some have asked whether they can also help us understand human agency. Specifically, could neuroimaging lead us to reassess the socially significant practice of assigning and taking responsibility?While responsibility itself is not a psychological process open to investigation through neuroimaging, decision‐making is. (...) Over the past decade, different researchers and scholars have sought to use neuroimaging (or the results of neuroimaging studies) to investigate what is going on in the brain when we make decisions. The results of this research raise the question whether neuroscience—especially now that it includes neuroimaging—can and should alter our understandings of responsibility and our related practice of holding people responsible. It is this question that we investigate here. (shrink)

In this note, we present a new observation of relevance to Aquinas’s third way. Scholars have noted that Aquinas recognizes the existence of a multiplicity of necessary beings, but it has not been recognized that Aquinas’s views concerning the eternality of the world commit him to the epistemic possibility that the world itself is a necessary being. We explain how Aquinas is committed to this possibility and explore its bearing on the success or failure of the third way as a (...) demonstration of God’s existence. (shrink)

We show that the theory, consisting of the usual axioms of but with the power set axiom removed—specifically axiomatized by extensionality, foundation, pairing, union, infinity, separation, replacement and the assertion that every set can be well‐ordered—is weaker than commonly supposed and is inadequate to establish several basic facts often desired in its context. For example, there are models of in which ω1 is singular, in which every set of reals is countable, yet ω1 exists, in which there are sets of (...) reals of every size, but none of size, and therefore, in which the collection axiom fails; there are models of for which the Łoś theorem fails, even when the ultrapower is well‐founded and the measure exists inside the model; there are models of for which the Gaifman theorem fails, in that there is an embedding of models that is Σ1‐elementary and cofinal, but not elementary; there are elementary embeddings of models whose cofinal restriction is not elementary. Moreover, the collection of formulas that are provably equivalent in to a Σ1‐formula or a Π1‐formula is not closed under bounded quantification. Nevertheless, these deficits of are completely repaired by strengthening it to the theory, obtained by using collection rather than replacement in the axiomatization above. These results extend prior work of Zarach. (shrink)

We introduce the resurrection axioms, a new class of forcing axioms, and the uplifting cardinals, a new large cardinal notion, and prove that various instances of the resurrection axioms are equiconsistent over ZFC with the existence of an uplifting cardinal.

Using the lottery preparation, we prove that any strongly unfoldable cardinal $\kappa$ can be made indestructible by all.

We introduce the strongly uplifting cardinals, which are equivalently characterized, we prove, as the superstrongly unfoldable cardinals and also as the almost-hugely unfoldable cardinals, and we show that their existence is equiconsistent over ZFC with natural instances of the boldface resurrection axiom, such as the boldface resurrection axiom for proper forcing.

In the Enneads Plotinus articulates an account of ‘creation’ following in the tradition, albeit critically, of Plato’s Timaeus. This article compares Hart’s account of creation, as expressed in The Beauty of the Infinite: The Aesthetics of Christian Truth , and other secondary literature, with that of Plotinus’s. Some significant differences and interesting parallels are highlighted.

Canada's enduring success has been based on trust--trust in each other; in our businesses, organizations, and markets; and in our public institutions and the officials who run them. David Johnston--reflecting on seven decades of personal experiences including seven years as Governor General--identifies the 20 ways we can make ourselves, our organizations, and our institutions even more worthy of trust, and in doing so build a better Canada for coming generations and the world. This new book is in part (...) a follow-up to The Idea of Canada, in that the author draws upon his own remarkable experience to illustrate where his strong convictions have come from. In this book, however, Johnston strikes notes that are more universally applicable than those in any of this earlier works. First, he speaks directly to the reader, offering practical advice about the attitudes, approaches, and habits that make a person trustworthy. Second, he offers compelling evidence that enduring community trust can be built with similarly simple techniques. Third, by drawing examples from Canadian and international experience, he shows how a whole nation can become trustworthy and, ultimately, trusted by its citizens, allies, trading partners and other societies. In short, Trust is a much needed manual for the repair of the one social quality on which all others are based. (shrink)

This book seeks to elucidate the concept of justice, not so much as it is expressed in law courts (retributive and procedural justice) or in state budgets (distributive justice), but as primary justice - what it means and how it can be grounded in the inalienable rights that each human being possesses qua human being. It draws inspiration from two recent works of philosopher Nicolas Wolterstorff, but also from the groundbreaking Islamic initiative of 2007, the Common Word Letter addressed by (...) 138 eminent Muslim scholars and clerics to the pope and all Christian leaders. This document affirmed that the two highest commandments in both Judaism and Christianity are also at the heart of the Islamic tradition - love of God and love of neighbor. In a style that lends itself to the classroom and beyond, the book's six chapters all begin with a case study of justice, so as to emphasize that justice must also be embodied in righteous social, political and economic practices. Along the way, leading contemporary scholars and activists from both traditions urge the reader - Muslim, Christian, or whatever - to look afresh at an age-old conundrum: how do justice and love interact so as to create a world in which everyone finds his or her rightful place?

Objective Ethical standards state research participation must be voluntary and free of coercion and undue influence, but what if a third party appears to engage in research-relevant coercion, without the researchers’ knowledge? This case study describes this type of situation and its resolution. Methods We are engaged in a randomized clinical trial evaluating pedestrian safety with 7- and 8- years old. Depending on children's rate of learning, families receive up to $1275 for their time. We recently learned a third-party “talent (...) agency,” a firm placing children in modeling and acting jobs, was referring families to our research with the expectation that families would share 20% of study reimbursements. Results We sensed clear impropriety, but identified no ethical violations on our part as researchers. Once paid a study reimbursement, participants can spend funds how they wish. We were concerned, however, that the third-party was exploitatively coercing families to participate. Conclusions We pursued four avenues to resolve the issue. First, we documented the situation to our university Institutional Review Board. Second, we contacted the talent agency and requested they stop referring families to our research. They agreed. Third, we retained children engaged in our study who were referred from the talent agency; removing them partway through the clinical trial could impact study results. In doing so, we explained that we were unaware of the talent agency referral and that they were not obligated by us to offer a portion of the study reimbursement to the talent agency. Last, we asked newly enrolled families about their referral source. (shrink)

Faces carry key personal information about individuals, including cues to their identity, social traits, and emotional state. Much research to date has employed static images of faces taken under tightly controlled conditions yet faces in the real world are dynamic and experienced under ambient conditions. A common approach to studying key dimensions of facial variation is the use of facial caricatures. However, such techniques have again typically relied on static images, and the few examples of dynamic caricatures have relied on (...) animating graphical head models. Here, we present a principal component analysis -based active appearance model for capturing patterns of spatiotemporal variation in videos of natural dynamic facial behaviours. We demonstrate how this technique can be applied to generate dynamic anti-caricatures of biological motion patterns in facial behaviours. This technique could be extended to caricaturing other facial dimensions, or to more general analyses of spatiotemporal variations in dynamic faces. (shrink)

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

The description for this book, The Rhetoric of Leviathan: Thomas Hobbes and the Politics of Cultural Transformation, will be forthcoming.

Liberalism, the founding philosophy of many constitutional democracies, has been criticized in recent years from both the left and the right for placing too much faith in individual rights and distributive justice. In this book, David Johnston argues for a reinterpretation of liberal principles he contends will restore liberalism to a position of intellectual leadership from which it can guide political and social reforms. He begins by surveying the three major contemporary schools of liberal political thought--rights-based, perfectionist, and (...) political liberalism--and, by weeding out their weaknesses, sketches a new approach he calls humanist liberalism. The core of Johnston's humanist liberalism is the claim that the purpose of political and social arrangements should be to empower individuals to be effective agents. Drawing on and modifying the theories of John Rawls, Michael Walzer, Ronald Dworkin, Joseph Raz, Amartya Sen, and others, Johnston explains how this purpose can be realized in a world in which human beings hold fundamentally different conceptions of the ends of life. His humanist liberalism responds constructively to feminist, neo-Marxist, and other criticisms while remaining faithful to the core values of the liberal tradition. (shrink)

More than five hundred years after Machiavelli wrote The Prince, his landmark treatise on the pragmatic application of power remains a pivot point for debates on political thought. While scholars continue to investigate interpretations of The Prince in different contexts throughout history, from the Renaissance to the Risorgimento and Italian unification, other fruitful lines of research explore how Machiavelli’s ideas about power and leadership can further our understanding of contemporary political circumstances. With Machiavelli on Liberty and Conflict, David (...) class='Hi'>Johnston, Nadia Urbinati, and Camila Vergara have brought together the most recent research on The Prince, with contributions from many of the leading scholars of Machiavelli, including Quentin Skinner, Harvey Mansfield, Erica Benner, John McCormick, and Giovanni Giorgini. Organized into four sections, the book focuses first on Machiavelli’s place in the history of political thought: Is he the last of the ancients or the creator of a new, distinctly modern conception of politics? And what might the answer to this question reveal about the impact of these disparate traditions on the founding of modern political philosophy? The second section contrasts current understandings of Machiavelli’s view of virtues in The Prince. The relationship between political leaders, popular power, and liberty is another perennial problem in studies of Machiavelli, and the third section develops several claims about that relationship. Finally, the fourth section explores the legacy of Machiavelli within the republican tradition of political thought and his relevance to enduring political issues. (shrink)

Abstract Hayek assailed the idea of social justice by arguing that any effort to realize it would transform society into an oppressive organization, stißing liberty. Hayek's view is marred by two omissions. First, he fails to consider that the goal of social justice, like the goal of wealth generation, might be promoted by strategies of indirection that do not entail oppressive organization. Second, he underestimates the tendency of the market order itself to generate oppressive organization, and consequently sees advantages in (...) the market order that it may not possess. (shrink)

Hayek claimed that the idea of social justice is meaningless in a market economy because in that context, no identifiable agent intentionally brings about the distribution of wealth. But the assumption that the existence of injustice entails an identifiable agent of injustice is erroneous. Moreover, Hayek ignores the fact that in a market economy, the broad pattern of economic outcomes is foreseeable even if detailed, person‐by‐person outcomes are not. Hayek's rejection of the idea of social justice reveals a striking naïveté (...) about his own ethical presuppositions. (shrink)

_John Dewey and Continental Philosophy_ provides a rich sampling of exchanges that could have taken place long ago between the traditions of American pragmatism and continental philosophy had the lines of communication been more open between Dewey and his European contemporaries. Since they were not, Paul Fairfield and thirteen of his colleagues seek to remedy the situation by bringing the philosophy of Dewey into conversation with several currents in continental philosophical thought, from post-Kantian idealism and the work of Friedrich Nietzsche (...) to twentieth-century phenomenology, hermeneutics, and poststructuralism. This unique volume includes discussions comparing and contrasting Dewey with the German philosophers G. W. F. Hegel, Friedrich Nietzsche, Martin Heidegger, and Hans-Georg Gadamer on such topics as phenomenology, naturalism, organicism, contextualism, and poetry. Others investigate a series of connections between Dewey and contemporary French philosophy, including the notions of subjectivity, education, and the critique of modernity in Michel Foucault; language and politics in Jacques Derrida; and the concept of experience in Gilles Deleuze. Also discussed is the question of whether we can identify traces of _Bildung_ in Dewey’s writings on education, and pragmatism’s complex relation to twentieth-century phenomenology and hermeneutics, including the problematic question of whether Heidegger was a pragmatist in any meaningful sense. Presented in intriguing pairings, these thirteen essays offer different approaches to the material that will leave readers with much to deliberate. _ John Dewey and Continental Philosophy_ demonstrates some of the many connections and opportunities for cross-traditional thinking that have long existed between Dewey and continental thought, but have been under-explored. The intersection presented here between Dewey’s pragmatism and the European traditions makes a significant contribution to continental and American philosophy and will spur new and important developments in the American philosophical debate.

The distribution of voting rights in the UK is an artefact of history rather than a product of clear legal or philosophical principles. Consequently, some resident aliens have the right to vote in all UK elections; others can vote in local elections but are excluded from national elections; still others are excluded from all elections. In England and Wales alone, roughly 2.3 million immigrants are excluded from voting in national elections. This exclusion is inconsistent with the founding principle of democracy (...) and distorts political discourse. What if all immigrants could vote in national elections? We estimate that up to ninety-five parliamentary seats could have been won by a different party in the 2015 general election. More substantially, enfranchising all immigrants would require re-drawing UK constituency boundaries. The new electoral map would increase the relative power of urban constituencies and would incentivise some political entrepreneurs and parties to temper anti-immigration rhetoric. (shrink)

This book presents a comprehensive critical survey of all the logical doctrines of the well-known but little understood Catalan philosopher and theologian, Ramon Llull (1232-1316). The highly idiosyncratic character of Llull's writings has long frustrated the efforts of general medieval historians to define his contribution to later scholastic culture, and has resisted attempts by specialists to explain exactly how his methods and procedures worked. This new study--the first book-length treatment in English of Llull's philosophy to appear in over fifty years--seeks (...) to resolve both of these difficulties. The author argues that Llull's peculiar logical doctrines result from his reinterpretation of the use of commonplace scholastic teachings according to his own preferred ethical and spiritual ideals.

The all too common sunk cost effect is apparent when an investor influenced by what has been spent already persists in a venture, committing further resources or foregoing more profitable opportunities, when the economically rational action is to quit. Less common but arguably just as much a sunk cost effect is the mistake of giving up on a failed or failing venture too readily, sometimes out of nothing but pique at what has been lost, or perhaps through the more subtle (...) psychological forces posited by Kahneman, Tversky, Thaler and others within prospect theory and related work on ``mental budgeting''. Two case examples are considered, wherein decision makers dissatisfied with the results of their investments, and having lost money, appear to compound their losses by selling out at prices less than their own estimates of the remaining financial worth of the failed assets. These decisions are evaluated from the perspectives of both behavioral and prescriptive economics, and are found to have possible explanations in both. Their prescriptive rationale assumes a portfolio theory of investment decisions, and is demonstrated within both expected utility (economics) and mean-variance (finance) frameworks. (shrink)
