Economic theory assumes that preferences are rational. However, experiments have found small violations of transitivity. This paper develops a model of rationality with preference discovery costs. Introspection is costly. Thus, agents may find it optimal to use less than full effort, even though this raises the risk of making a poor choice. This model could potentially explain the intransitivities observed in the data while retaining rationality and optimization.

Transhumance is a form of extensive livestock production that involves seasonal movements among ecological zones or landscape types. Rangeland-based transhumance constitutes an important social and economic relationship to nature in many regions of the world, including across the Western US. However, social and ecological drivers of change are reshaping transhumant practices, and managers must adapt to increased demands for public rangeland use. Specifically, concerns for wildlife conservation have led to reduced access to seasonal public lands grazing for western US livestock (...) producers. To understand how managers adapt to loss of grazing areas (called “seasonal ranges”) we create agroecological calendars from manager records spanning 35 years (1986–2021) at the US Sheep Experiment Station in Idaho and Montana, US. The calendars illustrate how a loss of winter and summer ranges after 2013 coincided with shifts in the operation’s adaptive strategies, leading to more grazing of fall crop residue and purchased winter feed, and reducing flexibility to move livestock to cope with variable forage conditions. These changes shifted the job duties and experiences of farm workers and managers, and raised several new questions related to sheep production and vegetation management outcomes that merit future research. Transhumant system transformation has implications for human relationships with nature, rural communities, sheep genetics, production, and vegetation communities. For livestock operations that rely on government-managed lands to sustain transhumant traditions, innovative forms of collaboration and social adaptation that help secure access to seasonal ranges will be as important as technological innovations to address biodiversity conservation, climate change adaptation, and food system sustainability issues that are reshaping access to grazing lands.

Autonomy operates as a key term in debates about the rights of families to choose distinct approaches to education. Yet, what autonomy means is often complicated by the actual circumstances and contexts of schools, families, and children. In this essay, Terri S. Wilson and Matthew A. Ryg focus on the challenges involved in translating an ideal of educational autonomy into the “nonideal” contexts and circumstances that surround families' choices. Drawing on the methodological insights of Elizabeth Anderson and John (...) Dewey, they sketch out a nonideal approach for exploring autonomy. Wilson and Ryg particularly focus on Dewey's notion of an ideal, his treatment of autonomy as a concept, and his view of the self. Such a nonideal approach draws attention toward the specific circumstances, habits, and environments that make autonomy possible. Wilson and Ryg illustrate the salience of this nonideal approach by exploring one example of an empirically engaged study of autonomy. (shrink)

Ours is an age full of desires but impoverished in its understanding of where those desires lead—an age that claims mastery over the world but also claims to find the world as a whole absurd or unintelligible. In The Vision of the Soul, James Matthew Wilson seeks to conserve the great insights of the western tradition by giving us a new account of them responsive to modern discontents. The western— or Christian Platonist—tradition, he argues, tells us that man (...) is an intellectual animal, born to pursue the good, to know the true, and to contemplate all things in beauty. Wilson begins by reconceiving the intellectual conservatism born of Edmund Burke’s jeremiad against the French Revolution as an effort to preserve the West’s vision of man and the cosmos as ordered by and to beauty. After defining the achievement of that vision and its tradition, Wilson offers an extended study of the nature of beauty and the role of the fine arts in shaping a culture but above all in opening the human intellect to the perception of the form of reality. Through close studies of Theodor W. Adorno and Jacques Maritain, he recovers the classical vision of beauty as a revelation of truth and being. Finally, he revisits the ancient distinction between reason and story-telling, between mythos and logos, in order to rejoin the two. Story-telling is foundational to the forms of the fine arts, but it is no less foundational to human reason. Human life in turn constitutes a specific kind of form—a story form. The ancient conception of human life as a pilgrimage to beauty itself is one that we can fully embrace only if we see the essential correlation between reason and story and the essential convertibility of truth, goodness and beauty in beauty. By turns a study in fundamental ontology, aesthetics, and political philosophy, Wilson’s book invites its readers to a renewal of the West’s intellectual tradition. (shrink)

Historians of modern design and sociology have shown little interest in the leaders of the ever resourceful and influential British Positivist Society. One of the aims of this essay is to show that the Positivist polymath Frederic Harrison (1831–1923) cultivated ideas and practices that are compatible with modernists’ aspirations to improve the lives of the masses. It is accordingly shown that Harrison was an ardent supporter of working-class causes and that on this basis he developed sociological survey methods and produced (...) social programmes to initiate the comprehensive reorganisation of cities. Harrison intended to realise a modern utopia called the “Occidental Republic”, created by Auguste Comte, the Positivist Philosopher who – during the 1830 and 1840s – introduced both sociology and the Religion of Humanity. While many studies pore over the Positivists’ “church” rituals, this essay is the first to argue that the Religion of Humanity and sociology were of equal consequence – and that together they formed the basis of their controversial spatial theory and practice, which was considered the means to realise Comte’s utopia. This vision, it is argued, is central to appreciating how Positivism percolated into the “modern movements” of architecture and planning. (shrink)

Embedding ethics modules within computer science courses has become a popular response to the growing recognition that CS programs need to better equip their students to navigate the ethical dimensions of computing technologies like AI, machine learning, and big data analytics. However, the popularity of this approach has outpaced the evidence of its positive outcomes. To help close that gap, this empirical study reports positive results from Northeastern’s program that embeds values analysis modules into CS courses. The resulting data suggest (...) that such modules have a positive effect on students’ moral attitudes and that students leave the modules believing they are more prepared to navigate the ethical dimensions they’ll likely face in their eventual careers. Importantly, these gains were accomplished at an institution without a philosophy doctoral program, suggesting this strategy can be effectively employed by a wider range of institutions than many have thought.

This paper examines one of the historical antecedents of Big Data, the social physics movement. Its origins are in the scientific revolution of the 17th century in Western Europe. But it is not named as such until the middle of the 19th century, and not formally institutionalized until another hundred years later when it is associated with work by George Zipf and John Stewart. Social physics is marked by the belief that large-scale statistical measurement of social variables reveals underlying relational (...) patterns that can be explained by theories and laws found in natural science, and physics in particular. This larger epistemological position is known as monism, the idea that there is only one set of principles that applies to the explanation of both natural and social worlds. Social physics entered geography through the work of the mid-20th-century geographer William Warntz, who developed his own spatial version called “macrogeography.” It involved the computation of large data sets, made ever easier with the contemporaneous development of the computer, joined with the gravitational potential model. Our argument is that Warntz's concerns with numeracy, large data sets, machine-based computing power, relatively simple mathematical formulas drawn from natural science, and an isomorphism between natural and social worlds became grounds on which Big Data later staked its claim to knowledge; it is a past that has not yet passed.

The purpose of this inquiry is to explore the experience of Borderline Personality Disorder with the aim of developing a more liberating approach to its diagnosis and treatment. Eight participants diagnosed with Borderline Personality Disorder were recruited from a psychiatric hospital operated by the Surrey and Borders NHS Trust and an outpatient daycentre based in London, United Kingdom. A narrative approach to methodology was employed to collect and analyse the participants’ life-stories. Themes to emerge from the participant’s narratives were found (...) to coincide with R.D. Laing’s concept of ontological insecurity. Ontological insecurity describes a number of aspects of the participant’s distress. To conclude, some general implications of this research for psychotherapy are briefly explored. (shrink)

This article revisits John Wilson’s “first steps” in moral education—a conceptual analysis of morality—and what he calls an education in morality. Education in morality focuses on morality as a form of life with a specific domain in which it aims to initiate students, and on education as a growth-oriented, progressive activity. Arendt’s conception of natality in education is then used to show how it provides a catalyst for growth, discovery, and tradition-trumping newness, and acts as a stepping-stone to public (...) action as morality and recognition of the plurality of human life. It becomes clear that the inherent sociability of morality forces the consideration of it as a public and social act. Education in morality must preserve the potential for the capacity to contribute to the development of morality and concurrently develop that capacity through the production of plurality that follows and the negotiations necessary for its preservation. Morality, then, must not be taught as a static set of immutable principles, but rather as an inclusive, adaptive process by and through which groups govern their associations. (shrink)

This text aims to perform a “fly over” the Philosophy for Children program--created by the philosopher and educator Matthew Lipman-–in order to identify certain philosophical problems that might appear there, one of them being the issue of universality. In response to Lipman’s claims of universality, we try to uncover his underlying ideological position that informs his approach to the concept. To achieve that goal, we return to the program’s beginnings, in order to ask how the idea of Philosophy for (...) Children appeared and how it has developed up to the present moment. We argue that Lipman’s novel proposal to think philosophically with children emerged, in part, as a response to the student movements of 1968--a response, that is, to a specific political context that was marked by strong social and ideological disputes. Finally, we make a comparative analysis of the social and political context that informs Latin American Philosophy, and the extent to which it, also, has been shaped by a pragmatic response to a particular historical moment. The difference between the Anglo-American and the Latin American contexts is here characterized as an obstacle to a certain “universal” logos to which the Lipmanian project is linked. Our analysis is aided by the Discourse of marginalization and barbarism, produced by the Mexican philosopher Leopoldo Zea. (shrink)

Talk of different types of cells is commonplace in the biological sciences. We know a great deal, for example, about human muscle cells by studying the same type of cells in mice. Information about cell type is apparently largely projectible across species boundaries. But what defines cell type? Do cells come pre-packaged into different natural kinds? Philosophical attention to these questions has been extremely limited [see e.g., Wilson (Species: New Interdisciplinary Essays, pp 187–207, 1999; Genes and the Agents of (...) Life, 2005; Wilson et al. Philos Top 35(1/2):189–215, 2007)]. On the face of it, the problems we face in individuating cellular kinds resemble those biologists and philosophers of biology encountered in thinking about species: there are apparently many different (and interconnected) bases on which we might legitimately classify cells. We could, for example, focus on their developmental history (a sort of analogue to a species’ evolutionary history); or we might divide on the basis of certain structural features, functional role, location within larger systems, and so on. In this paper, I sketch an approach to cellular kinds inspired by Boyd’s Homeostatic Property Cluster Theory, applying some lessons from this application back to general questions about the nature of natural kinds.

This article delineates the core concerns and motivations of the ontological work of Gilles Deleuze, and is intended as a programmatic statement for a general philosophical audience. The article consists of two main parts. In the first, two early writings by Deleuze are analysed in order to clarify his understanding of ontology broadly, and to specify the precise aim of his understanding of being in terms of difference. The second part of the article looks at the work of Heidegger and (...) Derrida in order to distinguish Deleuze's conceptions of ontology and difference from theirs. A final section clarifies Deleuze's efforts to undertake the construction of an ontology divergent from the dominant tradition and in contrast to the emphasis on the closure of metaphysics in the thought of Heidegger and Derrida.

ABSTRACT After the tragedies of the twentieth century, the utopian impulse was subject to searching criticism by a host of liberal intellectuals including Karl Popper, Hannah Arendt, Isaiah Berlin, and Jacob Talmon. Looking to history and political philosophy, these thinkers impugned utopianism for so frequently destroying the freedoms it appeared to pursue. Defined by its theoretical contradictions, the utopian project, rooted in the politics of the Enlightenment, bore some responsibility for the totalitarianism and genocide that had shaped their lives. As (...) this critique became liberal orthodoxy, a heretic group of anarchist thinkers challenged these conclusions. While travelling some distance with the liberal critics, for Paul Goodman, Marie Louise Berneri, and Herbert Read, the twentieth century, rather than invalidating the utopian urge made its boldness and experimentalism all the more vital. Their act of heresy was defending utopianism as a central component of their anarchist critique of the present. (shrink)

China and Islam examines the intersection of two critical issues of the contemporary world: Islamic revival and an assertive China, questioning the assumption that Islamic law is incompatible with state law. It finds that both Hui and the Party-State invoke, interpret, and make arguments based on Islamic law, a minjian law in China, to pursue their respective visions of 'the good'. Based on fieldwork in Linxia, 'China's Little Mecca', this study follows Hui clerics, youthful translators on the 'New Silk Road', (...) female educators who reform traditional madrasas, and Party cadres as they reconcile Islamic and socialist laws in the course of the everyday. The first study of Islamic law in China and one of the first ethnographic accounts of law in postsocialist China, China and Islam unsettles unidimensional perceptions of extremist Islam and authoritarian China through Hui minjian practices of law.

A far-reaching and influential view in evolutionary biology claims that species are cohesive units held together by gene flow. Biologists have recognized empirical problems facing this view; after sharpening the expression of the view, we present novel conceptual problems for it. At the heart of these problems is a distinction between two importantly different concepts of cohesion, what we call integrative and response cohesion. Acknowledging the distinction problematizes both the explanandum of species cohesion and the explanans of gene flow that (...) are central to the view we discuss. We conclude by tracing four broader implications for the study and conceptualization of species. (shrink)

Having no recourse to ways of knowing about the natural world, ethical non-naturalists are in need of an epistemology that might apply to a normative breed of facts or properties, and intuitionism seems well suited to fill that bill. Here I argue that the metaphysical inspiration for ethical intuitionism undermines that very epistemology, for this pair of views generates what I call the defeater from cosmic coincidence. Unfortunately, we face not a happy union, but a difficult choice: either ethical intuitionism (...) or ethical non-naturalism, but not both. (shrink)

Recent research in ethics education shows a potentially problematic variation in content, curricular materials, and instruction. While ethics instruction is now widespread, studies have identified significant variation in both the goals and methods of ethics education, leaving researchers to conclude that many approaches may be inappropriately paired with goals that are unachievable. This paper speaks to these concerns by demonstrating the importance of aligning classroom-based assessments to clear ethical learning objectives in order to help students and instructors track their progress (...) toward meeting those objectives. Two studies at two different universities demonstrate the usefulness of classroom-based, formative assessments for improving the quality of students’ case responses in computational modeling and research ethics.

This is a review of Eklund's book. It discusses his suggestion that "ardent realists" use the practical profiles of normative concepts to A) explain what it is for a concept to be normative, B) fix reference, and C) provide an extensional theory of normative properties. I argue that those sympathetic to ardent realism will be happier to focus on the way in which normativity presents itself to cognition, particularly that presentation of inherent, authoritative guidance, and whether that 1) explains what (...) it is for a concept to be normative, 2) fixes reference, 3) aptly characterizes the nature of normativity in the world, and perhaps 4) explains why normative thoughts have the Eklund-style normative roles—the practical profiles of things like motivation, preference, and intention—that they have.

Here I examine the major theories of ethical intuitions, focusing on the epistemic status of this class of intuitions. We cover self-evidence theory, seeming-state theory, and some of the recent contributions from experimental philosophy.

The view that it is better for life to be created free of disability is pervasive in both common sense and philosophy. We cast doubt on this view by focusing on an influential line of thinking that manifests it. That thinking begins with a widely-discussed principle, Procreative Beneficence, and draws conclusions about parental choice and disability. After reconstructing two versions of this argument, we critique the first by exploring the relationship between different understandings of well-being and disability, and the second (...) by more briefly focusing on the idea of a significant reason. By placing these results against the broader historical and ongoing contexts in which the lives of those with disabilities have been deemed of inferior quality, we conclude with a call for greater humility about disability and well-being in thought and practice.

There are ways that ethical intuitions might be, and the various possibilities have epistemic ramifications. This paper criticizes some extant accounts of what ethical intuitions are and how they justify, and it offers an alternative account. Roughly, an ethical intuition that p is a kind of seeming state constituted by a consideration whether p, attended by positive phenomenological qualities that count as evidence for p, and so a reason to believe that p. They are distinguished from other kinds of seemings, (...) such as those which are content driven (e.g., the sensory experience that a stick in water seems bent) and those which are competence driven (e.g., the intellectual seeming that XYZ is not water, or that one of DeMorgan’s laws is true). One important conclusion is this: when crafting a positive theory of justification ethical intuitionists have fewer resources than intuitionists in other domains, not because of the subject matter of ethical intuitions, but because of the their structure. A second conclusion is that the seemings featured in substantive ethical intuitions deliver relatively weak justification as compared to other seeming states. (shrink)

There are a number of proposals as to exactly how reasons, ends and rationality are related. It is often thought that practical reasons can be analyzed in terms of practical rationality, which, in turn, has something to do with the pursuit of ends. I want to argue against the conceptual priority of rationality and the pursuit of ends, and in favor of the conceptual priority of reasons. This case comes in two parts. I first argue for a new conception of (...) ends by which all ends are had under the guise of reasons. I then articulate a sense of rationality, procedural rationality, that is connected with the pursuit of ends so conceived, where one is rational to the extent that one is motivated to act in accordance with reasons as they appear to be. Unfortunately, these conceptions of ends and procedural rationality are inadequate for building an account of practical reasons, though I try to explain why it is that the rational pursuit of ends generates intuitive but misleading accounts of genuine normative reasons. The crux of the problem is an insensitivity to an is-seems distinction, where procedural rationality concerns reasons as they appear, and what we are after is a substantive sense of rationality that concerns reasons as they are. Based on these distinct senses of rationality, and some disambiguation of what it is to have a reason, I offer a critique of internalist analyses of one’s reasons in terms of the motivational states of one’s ideal, procedurally rational self, and I offer an alternative analysis of one’s practical reasons in terms of practical wisdom that overcomes objections to related reasons externalist views. The resulting theory is roughly Humean about procedural rationality and roughly Aristotelian about reasons, capturing the core truths of both camps. (shrink)

Differences between human beings have long been used to justify a range of degrading, exclusionary, and murderous practices that strip people of their humanity and dignity. While considerable scholarship has been devoted to such dehumanization, Matthew S. Weinert asks how we might conceive its reverse—humanization, or what it means to “make human.” Weinert proposes an account of making human centered on five mechanisms: reflection, recognition, resistance, replication of dominant mores, and responsibility. Examining cases such as the UN Security Council’s (...) engagements with crises and the International Court of Justice’s grappling with Kosovo’s unilateral declaration of independence, he illustrates the distinct and contingent ways these mechanisms have been deployed. Theoretically, the cases evince a complex, evolving relationship between state-centric and human-centric views of society, ultimately revealing the normative potentialities of both. Though the case studies concern specific human relations issues on an international level, Weinert argues in favor of starting from the shared problem of being human and of living in a world in which the humanity of countless groups has been demeaned or denied. Working outward from that point, he proposes, we obtain a more pragmatically grounded understanding of the social construction of the human being. (shrink)

Normative cognition seems rather important, even ineliminable. Communities that lack normative concepts like SHOULD, IS A REASON TO, JUSTIFIES, etc. seem cognitively handicapped and communicatively muzzled. And yet a popular metaethic, normative naturalism, has a hard time accommodating this felt ineliminability. Here, I press the argument against normative naturalism, consider some replies on behalf of normative naturalists, and suggest that a version of sophisticated subjectivism does the best job preserving the importance and ineliminability of the special, normative way of thinking.

It has become increasingly difficult for individuals to exercise meaningful control over the personal data they disclose to companies or to understand and track the ways in which that data is exchanged and used. These developments have led to an emerging consensus that existing privacy and data protection laws offer individuals insufficient protections against harms stemming from current data practices. However, an effective and ethically justified way forward remains elusive. To inform policy in this area, we propose the Ethical Data (...) Practices framework. The framework outlines six principles relevant to the collection and use of personal data—minimizing harm, fairly distributing benefits and burdens, respecting autonomy, transparency, accountability, and inclusion—and translates these principles into action-guiding practical imperatives for companies that process personal data. In addition to informing policy, the practical imperatives can be voluntarily adopted by companies to promote ethical data practices. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Matthew S. Santirocco JUSTICE IN SOPHOCLES' ANTIGONE Sophocles' Antigone is most often apprehended in terms of conflicts, an approach which the play does indeed invite. The personal clash of Antigone and Creon generates conflicts on many different levels— political (individual or family vs. state, aristocracy vs. democracy), theological (gods vs. men), philosophical (nature vs. law or convention), sexual (woman vs. man), even chronological (young vs. old). However, insofar (...) as no list can ever be so inclusive as the play itself, all such discussions tend by their very nature to be reductionist. And even if a balanced critique were possible at this level, a tragedy is not the sum of abstract conflicts; it is theatre, people in action. Furthermore, the conflict approach encourages us to ask the wrong questions. Although conflict need not imply resolution, critics persist in searching for it. Yet there is no resolution in the Antigone except by death. Similarly, such an approach invites us to ask who is right, Antigone or Creon. But in a very real sense this question misses Sophocles' point. Relevant, perhaps, to versions by Anouilh and Brecht, the question misleads when applied to the ancient play. It is interesting that we oversimplify, for Sophocles' sympathies are more expansive and complex than these modern interpretations of his myth. For all these reasons a valid alternative approach to the play may be to consider it not in terms of the conflicts incarnated in the personalities but rather in terms of one theme in the context of which all the conflicts are played out. The precise issue here, as so often in Greek tragedy, is a philosophical one. As the religious thought of an earlier era was yielding to judicial and political thought, and as older heroic ideals were being supplanted by a rationalistic view of man, tragedy's function in fifth-century Athens was, in part at least, to expose and explore these cultural displacements, either by affirming traditional values and concepts or else by questioning their continued validity. One such concept, perhaps the most recurrent in tragedy, 180 Matthew S. Santirocco181 is justice, dike. Originally a term used to refer to things as they are, dike came also to acquire a normative sense, things as they ought to be. At different times and in different contexts the word can signify custom or usage, law-enforcing authority, penalty, and ofcourse "justice" as a higher standard. Its precise semantic range is wide and fluctuating. Thus tragedy becomes, in a sense, a matter of vocabulary. In the Antigone the characters appeal to justice, but each defines it differently, so that the conflict is not so much between justice and injustice as between one sort of justice and another. The Oresteia of Aeschylus had earlier celebrated the transition from vendetta justice to courtroom justice. The Antigone, however, focuses not so much on the changes in dike as on a question these changes raise, namely the very possibility of dike. The establishment of the law court brought Aeschylus' trilogy to a resolved ending. Sophocles' vision in the Antigone is much more austere. Although he acknowledges the existence of an ideal of justice, he exposes the tensions and ambiguities inherent in it and thereby questions whether that ideal can ever be realized in the lives of men. II A key text concerning justice is contained in one of the choral odes. But can it be trusted? The tragic chorus is not, after all, the mouthpiece of the poet as was the comic chorus in Aristophanes' parabaseis. Nor is it always or necessarily the mouthpiece of the audience, SchlegeFs "ideal spectator." In the Antigone, as elsewhere, the chorus simply constitutes a panel of the population (here, of Thebes) and its perspective on the action is, if not omniscient, not particularly partisan either. Gordon Kirkwood has demonstrated the many dramatic functions of the Sophoclean chorus, including its ambiguities. In the Antigone no fewer than three odes are ambiguous, leaving in doubt the identity of the one who has disturbed order and right (332-75), who has violated the will of heaven (582-625), and whose mind has been perverted by love (781-816). Although the chorus may not be aware of the... (shrink)

Here I present and defend an etiological theory of objective, doxastic justification, and related theories of defeat and evidence. The theory is intended to solve a problem for reliabilist epistemologies— the problem of identifying relevant environments for assessing a process's reliability. It is also intended to go some way to accommodating, neutralizing, or explaining away many internalist-friendly elements in our epistemic thinking.

This article argues that the distinction between the sensible and the intelligible in Plato’s dialogues (here with respect to the Republic) is not a dogmaticassertion or the foundation for a set of doctrines, but is rather the very starting point of philosophical activity. This starting point will be shown to be, in its most fundamental aspect, not something chosen by the philosopher, but rather the attribute that makes the philosopher who he is. Much of my argument will turn on a (...) consideration of the divided line. In Part I, I situate the discussion of the divided line within both its global and immediate context in the Republic. As the divided line will serve as the focal point of my argument it is important to clarify its place in Socrates’ discussion with Glaucon and Adeimantus from the outset of my presentation. Part II consists of a brief analysis of the key passages devoted to the divided line. This analysis will culminate by highlighting the problematic nature of geometrical objects with respect to the schema of the line. I will argue that geometrical objects have no secure place on the line. This insecurity will call into question the apparent continuity between the sensible and the intelligible that the divided line suggests, and might call for a way to mediate or bridge the gap between the sensible and the intelligible. In Part III, I consider one such attempt in Proclus’s commentary on Euclid in order to show how such an attempt failson Platonic terms and thus cannot constitute the true core of Platonic philosophy. Part IV will argue that if rightly interpreted the divided line itself offers a solution to the problem and clarifies both the nature of philosophical activity and the status of the sensibility/intelligibility distinction within Platonic philosophy.
