In this paper we explore the relationship between norms of belief revision that may be adopted by members of a community and the resulting dynamic properties of the distribution of beliefs across that community. We show that at a qualitative level many aspects of social belief change can be obtained from a very simple model, which we call ‘threshold influence’. In particular, we focus on the question of what makes the beliefs of a community stable under various dynamical situations. We (...) also consider refinements and alternatives to the ‘threshold’ model, the most significant of which is to consider changes to plausibility judgements rather than mere beliefs. We show first that some such change is mandated by difficult problems with belief-based dynamics related to the need to decide on an order in which different beliefs are considered. Secondly, we show that the resulting plausibility-based account results in a deterministic dynamical system that is non-deterministic at the level of beliefs. (shrink)

We shed light on an old problem by showing that the logic LP cannot define a binary connective $\odot$ obeying detachment in the sense that every valuation satisfying $\varphi$ and $(\varphi\odot\psi)$ also satisfies $\psi$ , except trivially. We derive this as a corollary of a more general result concerning variable sharing.

Ceteris Paribus clauses in reasoning are used to allow for defeaters of norms, rules or laws, such as in von Wright’s example “I prefer my raincoat over my umbrella, everything else being equal”. In earlier work, a logical analysis is offered in which sets of formulas Γ, embedded in modal operators, provide necessary and sufficient conditions for things to be equal in ceteris paribus clauses. For most laws, the set of things allowed to vary is small, often finite, and so (...) Γ is typically infinite. Yet the axiomatisation they provide is restricted to the special and atypical case in which Γ is finite. We address this problem by being more flexible about ceteris paribus conditions, in two ways. The first is to offer an alternative, slightly more general semantics, in which the set of formulas only give necessary but not sufficient conditions. This permits a simple axiomatisation. (shrink)

Turing's (1936) analysis of effective symbolic procedures is a model of conceptual clarity that plays an essential role in the philosophy of mathematics. Yet appeal is often made to the effectiveness of human procedures in other areas of philosophy. This paper addresses the question of whether Turing's analysis can be applied to a broader class of effective human procedures. We use Sieg's (1994) presentation of Turing's Thesis to argue against Cleland's (1995) objections to Turing machines and we evaluate her proposal (...) to understand the effectiveness of procedures in terms of their reliability and precision. A number of conditions for effectiveness are identified and these are used to provide a general argument against the possibility of a Leibnizian decision procedure. (shrink)

We characterize a type of functional explanation that addresses why a homologous trait originating deep in the evolutionary history of a group remains widespread and largely unchanged across the group’s lineages. We argue that biologists regularly provide this type of explanation when they attribute conserved functions to phenotypic and genetic traits. The concept of conserved function applies broadly to many biological domains, and we illustrate its importance using examples of molecular sequence alignments at the intersection of evolution and cell biology. (...) We use these examples to show how the study of conserved functions can integrate knowledge of a trait’s causal effects on fitness and its history of natural selection without invoking adaptation. We also show how conserved function provides a novel basis for addressing objections against evolutionary functions raised by Robert Cummins. (shrink)

The problem of trust in social relationships was central to the emergence of the modern form of civil society and much discussed by social and political philosophers of the early modern period. Over the past few years, in response to the profound changes associated with postmodernity, trust has returned to the attention of political scientists, sociologists, economists, and public policy analysts. In this sequel to his widely admired book, The Idea of Civil Society, Adam Seligman analyzes trust as a (...) fundamental issue of our present social relationships. Setting his discussion in historical and intellectual context, Seligman asks whether trust--which many contemporary critics, from Robert Putnam through Francis Fukuyama, identify as essential in creating a cohesive society--can continue to serve this vital role. Seligman traverses a wide range of examples, from the minutiae of everyday manners to central problems of political and economic life, showing throughout how civility and trust are being displaced in contemporary life by new "external' system constraints inimical to the development of trust. Disturbingly, Seligman shows that trust is losing its unifying power precisely because the individual, long assumed to be the ultimate repository of rights and values, is being reduced to a sum of group identities and an abstract matrix of rules. The irony for Seligman is that, in becoming postmodern, we seem to be moving backward to a premodern condition in which group sanctions rather than trust are the basis of group life. (shrink)

Jeremy Sherman distills Terrence Deacon's breakthrough natural science hypothesis for the emergence of agents and agency, selves and aims in an otherwise aimless universe. The theory cuts a new path through the dualistic spirit vs. mechanism debate, unifying the hard and soft sciences and suggesting new solutions to philosophical mysteries.

Many philosophers think that free will requires alternative possibilities. Other philosophers deny this. There are plenty of philosophical arguments on both sides of this debate, but here I want to highlight various theological pressures that might push Christians into rejecting the principle of alternative possibilities. In this paper, I explore six cases that might push Christians in that direction: the case of divine foreknowledge, the case of prophecy, the case of the blessed in heaven, the case of Christ's human freedom, (...) the case of Mary's fiat in light of her immaculate conception, and the case of prayers for the past. As I will argue, in each of these cases, given certain other standard theological commitments, it seems that Christians are pushed to admit that the agent in question does indeed act freely but also that he or she did not possess alternative possibilities at the moment of decision.

Although the pedagogy literature indicates significant relationships between cheating intentions and both personal and situational factors, no published research has examined the joint effect of personal moral philosophy and perceived moral intensity components on students’ cheating intentions. Hence, a structural equation model that relates magnitude of consequences, relativism, and idealism to willingness to cheat, is developed and tested. Using data from undergraduate business students, the empirical results provide insight into these relationships and evidence of mediation for magnitude of consequences on (...) idealism and students’ cheating intentions. Implications for educators are offered. (shrink)

This paper argues that, if we are committed to a Pro-choice stance with regard to selective abortion for disability, we will be unable to justify the prohibition of sex-selective abortion (SSA), for two reasons. First, familiar Pro-choice arguments in favour of a woman’s right to select against fetal impairment also support, by parity of reasoning, a right to choose SSA. Second, rejection of the criticisms of selective abortion for disability levelled by disability theorists also disposes, by implication, of the key (...) objections to SSA, as developed, most notably, by feminists. The paper, then, consists of a conditional defence of SSA, under which SSA should be available, and protected by a right, if selective abortion for disability is. Opponents of SSA might respond by conceding additional restrictions on selection against disabled fetuses. It should become clear throughout the paper, however, that any such new restrictions would be unacceptably onerous for women. (shrink)

INTRODUCTION STATEMENT OF THE THESIS To the student of the social sciences it is interesting to observe the process by which, in one respect at least, ...

This groundbreaking handbook of character strengths and virtues is the first progress report from a prestigious group of researchers who have undertaken the systematic classification and measurement of widely valued positive traits. Character Strengths and Virtues classifies twenty-four specific strengths under six broad virtues that consistently emerge across history and culture. This book demands the attention of anyone interested in psychology and what it can teach about the good life.

The theories of cultural anthropologist Ernest Becker arise from an existential and psychological analysis of the death terror/anxiety deep in the unconscious of every human. Becker details how this anxiety governs the ideologies and behaviors of our species—something now confirmed by thousands of experiments performed by psychologists engaged in contemporary terror management theory (TMT). Humans manage their anxiety through what Becker terms “hero systems”—concepts, beliefs, and myths we create to give us a sense of significance and meaning during, and even (...) beyond our mortal lives. Today, many dominant economic, technological, and religious hero systems seek to confirm our significance by denying that we are—like all other species—animals who must exist in a decaying, mortal body. Becker shows how this attempt to deny our “creatureliness” (basic biological nature) causes humans to stand against the natural world we are embedded in, leading to an assault on the planet and nonhuman animals. As a result, Becker believed pacifism was the only hero system capable of keeping humankind from destroying itself and the earth. Pacifism is the precursor to the more encompassing ethical concept of “reverence for life,” advocated by Dr. Albert Schweitzer. By respecting the will-to-live in all sentient beings, reverence for life transcends concern for humans alone and extends moral and physical safeguards to life as such. Confronting the fact that humans are increasingly alienated from their commodified world and their own being, reverence for life stands as a vital solution to many of our modern problems. And following contemporary TMT research, reverencing life can also expand one’s self-esteem, which research shows lowers death anxiety, reduces aggression, and offers authentic meaning to life itself.

We often hear stories of people in terrible and seemingly intractable situations that are preyed upon by individuals offering empty promises of help. Frequently these cases are condemned as "exploiting the hope" of another. These accusations are made in a range of contexts, including human smuggling, the beauty industry, and unproven medical interventions. This concept is meant to do heavy lifting in public discourse, identifying a specific form of unethical conduct. However, it is poorly understood what is intended to be (...) wrong by exploiting hope, the range of activities that can accurately be captured under this concept, and what should be done about it. Thus, it is an ethical concept that is ripe for extended analysis and discussion. (shrink)

Field Life examines the practice of science in the field in the Great Plains and Rocky Mountains of the American West between the 1860s and the 1910s, when the railroad was the dominant form of long-distance transportation. Grounded in approaches from environmental history and the history of technology, it emphasizes the material basis of scientific fieldwork, joining together the human labor that produced knowledge with the natural world in which those practices were embedded. Four distinct modes of field practice, which (...) were shared by different field science disciplines, proliferated during this period—surveys, lay networks, quarries, and stations—and this book explores the dynamics that underpinned each of them. Using two diverse case studies to animate each mode of practice, as well as the making of the field as a place for science, Field Life combines textured analysis of specific examples of field science on the ground with wider discussion of the commonalities in the practices of a diverse array of field sciences, including the earth and physical sciences, the life and agricultural sciences, and the human sciences. By situating science in its regional environmental context, Field Life analyzes the intersection between the cosmopolitan knowledge of science and the experiential knowledge of people living in the field. Examples of field science in the Plains and Rockies range widely: geological surveys and weather observing networks, quarries to uncover dinosaur fossils and archaeological remains, and branch agricultural experiment stations and mountain biological field stations.

As our civilization careens toward climate breakdown, ecological destruction, and gaping inequality, people are losing their existential moorings. The dominant worldview of disconnection, which tells us we are split between mind and body, separate from each other, and at odds with the natural world, has been invalidated by modern science. Award-winning author, Jeremy Lent, investigates humanity's age-old questions -- Who am I? Why am I? How should I live? -- from a fresh perspective, weaving together findings from modern systems (...) thinking, evolutionary biology, and cognitive neuroscience with insights from Buddhism, Taoism, and Indigenous wisdom. The result is a breathtaking accomplishment: a rich, coherent worldview based on a deep recognition of connectedness within ourselves, between each other, and with the entire natural world. It offers a compelling foundation for a new philosophical framework that could enable humanity to thrive sustainably on a flourishing Earth. The Web of Meaning is for everyone looking for deep and coherent answers to the crisis of civilization. -- Amazon. (shrink)

Examines the political dimensions of Aristophanes’ comic poetry. This original and wide-ranging collection of essays offers, for the first time, a comprehensive examination of the political dimensions of that madcap comic poet Aristophanes. Rejecting the claim that Aristophanes is little more than a mere comedian, the contributors to this fascinating volume demonstrate that Aristophanes deserves to be placed in the ranks of the greatest Greek political thinkers. As these essays reveal, all of Aristophanes’ plays treat issues of fundamental political importance, (...) from war and peace, poverty and wealth, the relation between the sexes, demagoguery and democracy to the role of philosophy and poetry in political society. Accessible to students as well as scholars, The Political Theory of Aristophanes can be utilized easily in the classroom, but at the same time serve as a valuable source for those conducting more advanced research. Whether the field is political philosophy, classical studies, history, or literary criticism, this work will make it necessary to reconceptualize how we understand this great Athenian poet and force us to recognize the political ramifications and underpinnings of his uproarious comedies. Jeremy J. Mhire is Assistant Professor of Political Science at Louisiana Tech University. Bryan-Paul Frost is James A. and Kaye L. Crocker Endowed Professor of Political Science at the University of Louisiana at Lafayette and the coeditor (with Jeffrey Sikkenga) of History of American Political Thought. (shrink)

Differential privacy (DP) aims to confer data processing systems with inherent privacy guarantees, offering strong protections for personal data. But DP’s approach to privacy carries with it certain assumptions about how mathematical abstractions will be translated into real-world systems, which—if left unexamined and unrealized in practice—could function to shield data collectors from liability and criticism, rather than substantively protect data subjects from privacy harms. This article investigates these assumptions and discusses their implications for using DP to govern data-driven systems. In (...) Parts 1 and 2, we introduce DP as, on one hand, a mathematical framework and, on the other hand, a kind of real-world sociotechnical system, using a hypothetical case study to illustrate how the two can diverge. In Parts 3 and 4, we discuss the way DP frames privacy loss, data processing interventions, and data subject participation, arguing it could exacerbate existing problems in privacy regulation. In part 5, we conclude with a discussion of DP’s potential interactions with the endogeneity of privacy law, and we propose principles for best governing DP systems. In making such assumptions and their consequences explicit, we hope to help DP succeed at realizing its promise for better substantive privacy protections. (shrink)

A person can appropriately manifest respect toward a world heritage ruin by developing a sensitive understanding of the ruin’s cultural and historical context and significance. In this paper, we link such respectful understanding to the question of the aesthetic appreciation of world heritage ruins. Our claim is that an aesthetic appreciation of a world heritage ruin qua world heritage ruin typically involves two things: first, the responsibility not to neglect the individuality of the object, and, second, a commitment to the (...) idea that it is the object—respectfully conceived—which must be the focus of our appreciation.

This essay attempts to extend the exercise in normative pragmatics undertaken by Robert Brandom to include consideration of the logical relations between the practices of making of claims involving the use of the first-person-singular pronoun (‘I-talk’) and the making of claims involving the second-person-singular pronoun (‘You-talk’). The first part of the essay makes the case that the implicit response found in Brandom’s work affirms the pragmatic independence of I-talk from You-talk, such that it is possible to conceive of a discursive (...) practice involving people using the first person-singular pronoun but not the second-person. The second part argues this response is mistaken, as there are reasons internal to Brandom’s own project that require pragmatic interdependence of I-talk and You-talk. The upshot of this exercise is normative pragmatics is thus that there can be no ‘I’ without a ‘You’. (shrink)

Commentators have often been puzzled by the structure of the Symposium; in particular, it is unclear what the relationship is between Socrates’ speech and that of the other symposiasts. This chapter seeks to make a contribution to that debate by highlighting parallels between the first four speeches of the Symposium and the goals of the early education in the Republic. In both dialogues, I contend, we see Plato concerned with educating people through (a) activating and cultivating spirited motivations, (b) becoming (...) lawful and taking virtue as a goal, (c) harmonizing the opposing forces in their soul, and (d) minimizing the appetites and making them orderly. While these are familiar points from the moral education of the Republic, I argue that they also map onto the first four speeches of the Symposium respectively. Because in the Republic this moral education is necessary to make progress on the epistemic ascent, we can speculate that there is a similar point to be made in the Symposium – without first training our character adequately, we will not be able to climb the ladder of love. While the positive effects of Eros described in the early speeches of the Symposium are only imitations of the ideal education regime of Kallipolis, they nevertheless improve one’s character in such a way that better prepares the soul for philosophy. Finally, I argue that the importance of this moral education is dramatized at the end of the Symposium through Agathon’s amicable refutation by Socrates on the one hand, and the drunken entrance of Alcibiades on the other. Agathon shows potential for philosophy whereas Alcibiades is the exemplar of what happens when somebody comes to philosophy without a harmonized soul. (shrink)

This chapter is an investigation into G. E. M. Anscombe's suggestion that there can be cases where belief takes a personal object, through an examination of the role that the activity of teaching plays in Anscombe's discussion. By contrasting various kinds of ‘teachers’ that feature in her discussion, it is argued that the best way of understanding the idea of believing someone personally is to situate the relevant encounter within the social, conversational framework of ‘engaged reasoning’. Key features of this (...) framework are highlighted, and are used to characterise the distinctive kind of teaching and learning germane to Anscombe's suggestion. (shrink)

Hybrid languages have both modal and first-order characteristics: a Kripke semantics, and explicit variable binding apparatus. This paper motivates the development of hybrid languages, sketches their history, and examines the expressive power of three hybrid binders. We show that all three binders give rise to languages strictly weaker than the corresponding first-order language, that full first-order expressivity can be gained by adding the universal modality, and that all three binders can force the existence of infinite models and have undecidable satisfiability (...) problems.

This chapter draws on Schelling's insights about evil to show that the reason we find Ender's Game so disturbing is that it points to unnerving facts about our own lives. One thing that Schelling can help us to notice is that by becoming a selfish monster, Ender passes through an essential phase in his moral development. Card's Ender's Game is disturbing not only because of what its protagonist does and the manipulation that led him to it. It's discomfiting because it (...) points to something all suspect about us: that our freedom is really a product of forces that can't detect or even imagine. Ender's Game is thus revealed as a meditation on the interplay of freedom and fate that defines all of our lives. (shrink)
