In [3], two different effective versions of Borel embedding are defined. The first, called computable embedding, is based on uniform enumeration reducibility, while the second, called Turing computable embedding, is based on uniform Turing reducibility. While [3] focused mainly on computable embeddings, the present paper considers Turing computable embeddings. Although the two notions are not equivalent, we can show that they behave alike on the mathematically interesting classes chosen for investigation in [3]. We give a “Pull-back Theorem”, saying that if (...) Φ is a Turing computable embedding of K into K’, then for any computable infinitary sentence φ in the language of K’, we can find a computable infinitary sentence φ* in the language of K such that for all.

"Literature and the Right to Marriage," which bears the same title as the special issue that it introduces, takes up the challenge of the claim that marriage is a universal right. Framing the questions that traverse the five essays in the collection with a close reading of the sections on marriage from Hegel's Elements of the Philosophy of Right, the authors argue that if marriage can be considered a right, this right both guarantees access to and is founded upon each (...) partner's vow to abide by his or her vows to the other. Hegel's text is important because it underscores the linguistic dimension of the marriage ceremony; and it thus helps to show that, if the right to marriage were universal, it must be understood as the right to an irreplaceable kind of ritual speech. Moreover, this text is remarkably modern in its emphasis upon love as the condition of rightful marriage. Hegel considered the exchange of marriage vows to be a political event at which love becomes ethical , and ethics becomes political ; and thus also the point at which the model for "ethical love" becomes the verbally solemnized love between a man and a woman rather than the priestly love of the neighbor. Marriage, for Hegel, is always a turning point, both in the lives of the couple and in the history of the state. But this means that the importance of any marriage cannot be measured in terms of a norm; it can only be measured in terms of the amorous situation that precedes the event of marriage. Hegel's analyses are indispensable for grasping the stakes of the essays collected in this special issue and for addressing contemporary questions about which couples have the right to marry and what marriage becomes when those who would marry already have shared long and complex lives together.

The evolution of humans required performing increasingly hierarchically complex tasks within multiple domains. Hierarchical complexity increases task by task. Tasks occur within, and differ by, determinable domains, their stages of performance measurable using the Model of Hierarchical Complexity. How well one performs within single and multiple domains is considered to indicate intelligence. Original task-initiation is more difficult than imitational learning and can create new domains. Levels of support reduce task difficulty, increasing performance. Task-performance may be generalized to other domains. Stages (...) of developing tools and empathy are presented to demonstrate domains' roles in the evolution of human intelligence. (shrink)

This paper examines the outcomes of Preserving the Past Together, a workshop series designed to build the capacity of local heritage managers to engage in collaborative and community-based approaches to archaeology and historic preservation. Over the past two decades practitioners of these approaches have demonstrated the interpretive, methodological, and ethical value of integrating Indigenous perspectives and methods into the process and practice of heritage management and archaeology. Despite these benefits, few professional resources exist to support the development of collaborative relationships (...) between local heritage managers and Tribal nations. Filling this need, Preserving the Past Together’s interactive workshops and keynote lectures involved participants in a discussion of the central themes in collaborative and Indigenous approaches to archaeology today, highlighting the local challenges and opportunities that exist for archaeologists, heritage managers, and Tribal nations to work together to care for the past. This paper presents an overview of the event series’ goals, the strategies it used to foster collaboration among the diverse stakeholders of the Salish Sea, and the next steps the project’s co-directors are taking to further support communication and collaboration between stewards and stakeholders in the Pacific Northwest.

Although informed consent is important in clinical research, questions persist regarding when it is necessary, what it requires, and how it should be obtained. The standard view in research ethics is that the function of informed consent is to respect individual autonomy. However, consent processes are multidimensional and serve other ethical functions as well. These functions deserve particular attention when barriers to consent exist. We argue that consent serves seven ethically important and conceptually distinct functions. The first four functions pertain (...) principally to individual participants: (1) providing transparency; (2) allowing control and authorization; (3) promoting concordance with participants' values; and (4) protecting and promoting welfare interests. Three other functions are systemic or policy focused: (5) promoting trust; (6) satisfying regulatory requirements; and (7) promoting integrity in research. Reframing consent around these functions can guide approaches to consent that are context sensitive and that maximize achievable goals. (shrink)

S. Sara Monoson challenges “the canonical view of Plato as a virulent antidemocrat”. More precisely, she undertakes “to render problematic the standard view that Plato’s texts are unequivocally hostile to democracy”. “Although Plato’s dialogues are unquestionably and radically critical of elements of Athenian democracy, it is not accurate to claim further that they attack democracy unrelentingly”. Rather, “Plato’s dialogues contain explicit, albeit qualified, expressions of acceptance of the wide dispersal of political power characteristic of democracy, enlist certain celebrated Athenian (...) democratic principles in the design of his critique of democratic politics, and depict the practice of philosophy as indebted to Athenian democratic culture”. On this basis Monoson denies that Plato “is unambiguously opposed to democratic culture.” On the contrary “the ethos and culture of democratic Athens subtly informs his presentation of the work of philosophy”.

In lieu of an abstract, here is a brief excerpt of the content:The Evolution of the Society for the Advancement of American PhilosophyJames Campbelldespite my increasingly decrepit appearance, I can lay no claim to being one of the founders of SAAP. When I joined the Society in the mid-1970s, it was already a well-functioning organization—if a much smaller one than today. After a few years of attending meetings, I began to submit papers, and I first appeared on the program at (...) our sixth annual meeting at John Carroll University in 1979. (See Fig. 1, the complete program, below.) While I was not one of the founders of SAAP, I did know them all. Presiding at the early meetings were, in the order of their presidencies, such elders as John Lachs, John J. McDermott, Darnell Rucker, James Gouinlock, Beth J. Singer, Peter H. Hare, Sandra B. Rosenthal, Thelma Z. Lavine, Joseph Betz, Charlene Haddock Seigfried, and Andrew J. Reck. Serving in the background at the same time were such patron saints as Justus Buchler, Douglas Greenlee, Abraham Edel, Max Harold Fisch, Elizabeth Flower, Edward H. Madden, David L. Miller, Frank M. Oppenheim, Evelyn Shirk, John E. Smith, and H. S. Thayer. It was a good time to be coming to American Philosophy, under the guidance of a Society that respected the fundamentals of pluralism and "fallibilism."1IThe brief discussion of the evolution of SAAP that I offer here initially emphasizes what the Society has meant to me over nearly five decades.2 As I was entering graduate school in 1974, I was drawn by the American philosophical tradition. It was, as William James writes, my "dumb conviction" that the best answers were to be found in this philosophical direction and not in the others, and that my job was to pursue these answers.3 What I found in this tradition was a refuge from both the analytic style of philosophy then dominant in America, with what I saw as its obsession with truth4 and its [End Page 1] confusion of cleverness with wisdom, and the alternatives of the various continental traditions that, although they pursued wisdom, seemed to me to rely too strongly on the mysterious or the untranslatable. My own sense of the American philosophical tradition at the time was an amalgam of Puritanism, Deism, Transcendentalism, Pragmatism in its various forms, and a large dose of Columbia Naturalism. Through further study and especially through my interactions at SAAP meetings, I became more grounded in these approaches and more open to other strands within the tradition.5 For me, cooperative interaction with others was essential to further understanding. Just as for Josiah Royce, the secret was "the community."6Among the lessons that I drew from the American philosophical tradition were the following. I knew that it was necessary to resist the human tendency to believe that what works for me will work for everyone else. As George Santayana reminds us, all philosophy is "personal."7 Thus, certain thinkers and certain thoughts will benefit from their initial plausibility to us, and other thoughts and thinkers will be initially suspect. To counter this personal prejudice, we need to partake in careful, long-term study. On a related point, Ralph Waldo Emerson urges us to seek insight from others, to accept what he calls "provocation" while not accepting their answers.8 At the same time, we live among these other individuals, marry them, teach their children, and benefit from their contributions to our social existence. In other words, American Philosophy teaches us that people are social creatures—a point which both Emerson and James were wary of, but not blind to—and that our thinking should focus on the world of shared experience. As Benjamin Franklin writes, our efforts in "Philosophy" make sense only when our pursuit of wisdom is related to human well-being.9 This point is so important that we need to wonder how our efforts were ever allowed to narrow and separate from a broad sense of human welfare to focus upon supposedly more important minutiae. With John Dewey, I saw the job of philosophers to be helping individuals to understand and deal with their philosophical "problems" of living.10 And, perhaps more... (shrink)

In this article, we explore how deep brain stimulation (DBS) devices designed to “close the loop”—to automatically adjust stimulation levels based on computational algorithms—may risk taking the individual agent “out of the loop” of control in areas where (at least apparent) conscious control is a hallmark of our agency. This is of particular concern in the area of psychiatric disorders, where closed-loop DBS is attracting increasing attention as a therapy. Using a relational model of identity and agency, we consider whether (...) DBS designed for psychiatric regulation may require special attention to agency. To do this, we draw on philosophical work on relational identity and agency, connecting it with reports from people using first-generation DBS devices for depression and obsessive-compulsive disorder. We suggest a way to extend a notion of relational agency to encompass neural devices. (shrink)

This collection of thirteen essays, when viewed together, offers a unique perspective on the history of American philosophy. It illuminates for the first time in book form, how thirteen major American philosophical thinkers viewed a problem of special interest in the American philosophical tradition: the relationship between experience and reflection. Written by well-known authorities on the figure about which he or she writes, the essays are arranged chronologically to highlight the changes and developments in thought from Puritanism to Pragmatism to (...) Process Philosophy. While Doctrine and Experience will be of particular interest to specialists in American Philosophy, there is also much to offer anyone interested in the intellectual and cultural history of the United States.

This paper aims to reconfigure the place of memory in epistemology. I start by rethinking the problem that memory systems solve; rather than merely functioning to store information, I argue that the core function of any memory system is to support accurate and relevant retrieval. This way of specifying the function of memory has consequences for which structures and mechanisms make up a memory system. In brief, memory systems are modeling systems. This means that they generate, update and manage a (...) series of overlapping, simplified, relational representations that map out features of the world. Succeeding at building and maintaining models requires the kind of active knowledge generation traditionally associated only with deliberative reasoning. (shrink)

A comprehensive examination of Kristeva's work from the seventies to the nineties.

We argue that in implanted neurotechnology research, participants and researchers experience what Henry Richardson has called “moral entanglement.” Participants partially entrust researchers with access to their brains and thus to information that would otherwise be private, leading to created intimacies and special obligations of beneficence for researchers and research funding agencies. One of these obligations, we argue, is about continued access to beneficial technology once a trial ends. We make the case for moral entanglement in this context through exploration of (...) participants’ vulnerability, uncompensated risks and burdens, depth of relationship with the research team, and dependence on researchers in implanted neurotechnology trials.

Despite the enormous progress made in the advancement of health technologies over the last century, infectious diseases continue to cause significant morbidity and mortality in developing countries. Neglected diseases are a subset of infectious diseases that lack treatments that are effective, simple to use, or affordable. Neglected diseases primarily affect populations in poor countries that do not constitute a lucrative market sector, thus failing to provide incentives for the pharmaceutical industry to conduct R&D for these diseases. Of the treatments that (...) do exist for neglected diseases, most are completely out-dated, with poor side-effect profiles, cumbersome logistics of administration, and inadequate efficacy. Historically, the impetus for a majority of neglected disease research was driven by early 20th-century colonialism, and in the post-colonial era, these diseases have been virtually ignored. Of the 1556 New Chemical Entities brought to market during the 30-year period from 1975 to 2004, only 20 — less than 0.02% — were for neglected diseases. (shrink)

Both adults’ habits-of-thought and their understanding of children’s stories shape how adults interpret children’s participation in conversations. In the light of the requests on children’s rights that follow from the Convention on the Rights of the Child (CRC) this paper stresses the relevance of authorities having semiotically informed knowledge on children’s meaning-making within conversations with adults. In Article 12, the CRC stipulates the right of children to participate in and to be heard about decisions that affect their everyday lives. According (...) to the same Article, however, these rights can be restrained, based on the authority’s judgements of the child’s age and maturity. Sociological studies have highlighted the importance of adopting the child’s perspective in judging matters that concern her. The present paper further suggests that narrow conceptualization of the sign can help one to observe different levels of meaning in adults’ and children’s conversations better. Although Paul Ricoeur did not investigate children’s narratives per se, his theory of narratives and narrativity offers a phenomenological approach to development that allows for better theoretical discriminations of narrative as a semiotic resource, and can thus assist adults in truly listening to children.

While the contemporary philosophical literature is replete with discussion of the control or freedom required for moral responsibility, only more recently has substantial attention been devoted to the knowledge or awareness required, otherwise called the epistemic condition. This area of inquiry is rapidly expanding, as are the various positions within it. This chapter introduces two major positions: the reasonable expectation view and the quality of will view. The chapter then explores two dimensions of the epistemic condition that serve as fault (...) lines along which these two views diverge. The first dimension concerns different kinds of ignorance. The second concerns what agents can be directly blameworthy for. The chapter closes by sketching a novel approach that incorporates advantages of opposing positions on this topic. (shrink)

What does the term academic ethics mean? How does this term relate to others in the academic integrity literature, such as research misconduct? Does conceptual confusion in the study of academic ethics complicate development of valid analyses of ethical behavior in an academic setting? The intended goal of many empirical projects on academic ethics is to draw causal conclusions about the factors that lead to faculty or students possessing or disregarding academic integrity. Yet, it is not clear that scholars using (...) the concept academic ethics are measuring the same phenomenon when they use associated concepts, such as responsible conduct of research. The purpose of this paper is to develop a taxonomy of concepts for the empirical study of academic ethics. Based in research on comparative analysis of democracy, another normatively preferable but multifaceted concept, I argue for a taxonomy of concepts for the study of academic integrity that reduces problems of “conceptual stretching” and challenges to the validity of empirical research in this field.

Recent advances in immunology have provided a foundation of knowledge to understand many of the intricacies involved in manipulating the human response to fight parasitic infections, and a great deal has been learned from malaria vaccine efforts regarding strategies for developing parasite vaccines. There has been some encouraging progress in the development of a Chagas vaccine in animal models. A prize fund for Chagas could be instrumental in ensuring that these efforts are translated into products that benefit patients.

This qualitative study examines the expectations and beliefs parents, students, and teachers have about the teaching of heritage histories in public high schools. Students from three heritage groups, as well as their parents and teachers, were interviewed to shed light on this complex, often silent, relationship. This study is grounded in literature about the purposes of history education, historical distance, and collective memory/heritage, which give shape to and help to explicate some of the more complex issues inherent in the teaching (...) of heritage histories. Participants included four Hmong students, three of their parents, and their teacher in St. Paul, Minnesota; eight Chinese students, nine of their parents, and their teacher in Elmdale, California; and five Jewish students, five of their parents, and their teacher in Maple Lake, Illinois. Findings indicate that the three stakeholder groups believe that the public school history classroom is an appropriate and desired place for heritage histories to be taught. This is complicated, however, by several factors: the placement of the heritage history narratives within larger curricular and mainstream narratives, how the teachers choose to incorporate the heritage narratives into the formal classroom curriculum, and the changing nature of historical and generational distance.

The politics of populism is the politics of belonging. It reflects a deep challenge to the liberal democratic state, which attempts to maintain social boundaries (as an imperative of state capacity) but also allow immigration. Boundaries—established through citizenship and norms of belonging—must be both coherent and malleable. Changes to boundaries become sites of contestation for exclusionary populists in the putative interest of “legitimate” citizens. Populism is an inevitable response to liberal democratic adjustment; any liberal democracy that redefines citizenship opens itself (...) to populist challenge. (shrink)

The chapter studies the ethical dimensions of Beauvoir’s existentialism and Irigaray’s ontology of difference. It argues that Irigaray builds on one central but largely neglected result of Beauvoir’s moral philosophical argumentation: the claim that fundamentally sexual subordination constitutes an ethical problem that cannot be adequately solved merely through social reforms, political interventions, or theoretical reflections. By comparing Beauvoir’s concept of erotic generosity to Irigaray’s discussion of wonder and love, the chapter demonstrates that both philosophers conceive of male privilege as an (...) ethical issue that must be worked out between individual women and men in their concrete encounters. The task is to reform and cultivate not just human behaviors, actions, beliefs and cognitions, but also one’s own emotions and desires. (shrink)

The main result of this paper is a normalizing system of natural deduction for the full language of intuitionistic linear logic. No explicit weakening or contraction rules for -formulas are needed. By the systematic use of general elimination rules a correspondence between normal derivations and cut-free derivations in sequent calculus is obtained. Normalization and the subformula property for normal derivations follow through translation to sequent calculus and cut-elimination.

Temporal dynamists typically hold that it seems to us as though time robustly passes, and that its seeming so is explained by the fact that time does robustly pass. Temporal non-dynamists hold that time does not robustly pass. Some non-dynamists nevertheless hold that it seems as though it does: we have an illusory phenomenal state whose content represents robust passage. Call these phenomenal passage illusionists. Other non-dynamists argue that the phenomenal state in question is veridical and represents something other than (...) robust passage. Call this the veridical passage-less view. This paper argues in favour of the latter view over the former, by arguing that we should reject passage illusionism. (shrink)

The origin of moral agency is a much-debated issue. While rationalists or Kantians have argued that moral agency is rooted in reason, sentimentalists or Humeans have ascribed its origin to empathic feelings. This debate between rationalists and sentimentalists still stands with respect to persons with mental disorders, such as individuals diagnosed with mild forms of Autism Spectrum Disorder, without intellectual impairment. Individuals with ASD are typically regarded as moral agents, however their ability for empathy remains debated. The goal of this (...) paper is to investigate the mechanisms of moral actions in people with ASD, by finding arguments for the origin of their moral actions, supporting either the sentimentalist or the rationalist view of the dispute. We propose to revisit the debate using Interpretative Phenomenological Analysis to study the autobiographies of individuals with High-Functioning Autism and Asperger Syndrome. While conducting the systematic analysis of 10 autobiographies, we re-examined both the rationalist and the sentimentalist positions, considering the links between empathic feelings and moral agency. The investigation of the temporal dimensions of emotional experiences, an aspect overlooked by previous research, indicated that individuals with ASD empathize with others, but in different ways as compared to neurotypicals. A relationship between emotional experience and the type of moral agency exhibited by individuals with forms of ASD was established. As a consequence, our analyses support the sentimentalist stance on moral action. (shrink)

This article argues for a clearer framework of internet-based “memes”. The science of memes, dubbed ‘memetics’, presumes that memes remain “copying units” following the popularisation of the concept in Richard Dawkins’ celebrated work, The Selfish Gene (1976). Yet Peircean semiotics and biosemiotics can challenge this doctrine of information transmission. While supporting a precise and discursive framework for internet memes, semiotic readings reconfigure contemporary formulations to the – now-established – conception of memes. Internet memes can and should be conceived, then, as (...) habit-inducing sign systems incorporating processes involving asymmetrical variation. So, drawing on biosemiotics, Tartu-Moscow semiotics, and Peircean semiotic principles, and through a close reading of the celebrated 2011 Internet meme Rebecca Black’s Friday, this article proposes a working outline for the definition of internet memes and its applicability for the semiotic analysis of texts in new media communication.

We examined how children’s strategy choices in solving complex subtraction problems are related to grade and to variations in problem complexity. In two studies, third- and fifth-grade children (N≈160 each study) solved multi-digit subtraction problems (e.g., 34 - 18) and described their solution strategies. In the first experiment, strategy selection was investigated by means of a free-choice paradigm, whereas in the second study a discrete-choice approach was implemented. In both experiments, analyses of strategy repertoire indicated that third-grade children were more (...) likely to report less-efficient strategies (i.e., counting) and relied more on the right-to-left solution algorithm compared to fifth-grade children who more often used efficient memory-based retrieval and conceptually-based left-to-right (i.e., decomposition) strategies. Nevertheless, all strategies were reported or selected by both older and younger children and strategy use varied with problem complexity and presentation format for both age groups. These results supported the overlapping waves model of strategy development and provide detailed information about patterns of strategy choice on complex subtraction problems. (shrink)

At the beginning of Being and Time, Heidegger rejects Husserl’s classical phenomenology on three grounds: he claims that Husserlian phenomenology is impaired by indeterminate concepts, by naïve personalism, and by obscurities in its account of individuation. The paper studies the validity of this early critique by explicating Husserl’s discourse on human persons as bodily-spiritual beings and by clarifying his account of the principles by which such beings can be individuated. The paper offers three types of considerations. After a summary of (...) Heidegger’s early critique of Husserl, the second section of the paper distinguishes between two dimensions of Husserl’s discourse on human persons. It argues that Husserl does not put forward one analysis of the being of humans, but explicates two different accounts and then studies critically their mutual relations of dependency: on the one hand, the naturalistic account of human beings as layered beings and on the other hand the personalistic account of human beings as peculiar kinds of unified wholes in which the mental and the bodily are inextricably intertwined. The third section of the paper clarifies Husserl’s theory of individuation and its consequences for our discourse on human persons. Finally, the fourth section explicates the conceptual means by which Husserl develops his account of human beings as persons. The paper ends in drawing some conclusions for contemporary philosophical anthropology. (shrink)

Traditional flat-structured bigram and trigram models of phonotactics are useful because they capture a large number of facts about phonological processes. Additionally, these models predict that local interactions should be easier to learn than long-distance ones because long-distance dependencies are difficult to capture with these models. Long-distance phonotactic patterns have been observed by linguists in many languages, who have proposed different kinds of models, including feature-based bigram and trigram models, as well as precedence models. Contrary to flat-structured bigram and trigram (...) models, these alternatives capture unbounded dependencies because at an abstract level of representation, the relevant elements are locally dependent, even if they are not adjacent at the observable level. Using an artificial grammar learning paradigm, we provide additional support for these alternative models of phonotactics. Participants in two experiments were exposed to a long-distance consonant-harmony pattern in which the first consonant of a five-syllable word was [s] or [∫] (“sh”) and triggered a suffix that was either [-su] or [-∫u] depending on the sibilant quality of this first consonant. Participants learned this pattern, despite the large distance between the trigger and the target, suggesting that when participants learn long-distance phonological patterns, that pattern is learned without specific reference to distance.

In 1968, Orevkov presented proofs of conservativity of classical over intuitionistic and minimal predicate logic with equality for seven classes of sequents, what are known as Glivenko classes. The proofs of these results, important in the literature on the constructive content of classical theories, have remained somehow cryptic. In this paper, direct proofs for more general extensions are given for each class by exploiting the structural properties of G3 sequent calculi; for five of the seven classes the results are strengthened (...) to height-preserving statements, and it is further shown that the constructive and minimal proofs are identical in structure to the classical proof from which they are obtained.
