When searching for concepts in memory—as in the verbal fluency task of naming all the animals one can think of—people appear to explore internal mental representations in much the same way that animals forage in physical space: searching locally within patches of information before transitioning globally between patches. However, the definition of the patches being searched in mental space is not well specified. Do we search by activating explicit predefined categories and recall items from within that category, or do we (...) activate and recall a connected sequence of individual items without using categorical information, with each item recalled leading to the retrieval of an associated item in a stream, or both? Using semantic representations in a search of associative memory framework and data from the animal fluency task, we tested competing hypotheses based on associative and categorical search models. Associative, but not categorical, patch transitions took longer to make than position-matched productions, suggesting that categorical transitions were not true transitions. There was also clear evidence of associative search even within categorical patch boundaries. Furthermore, most individuals' behavior was best explained by an associative search model without the addition of categorical information. Thus, our results support a search process that does not use categorical information, but for which patch boundaries shift with each recall and local search is well described by a random walk in semantic space, with switches to new regions of the semantic space when the current region is depleted.

The fifth base in human DNA, 5‐methylcytosine, is inherently mutagenic. This has led to marked changes in the distribution of the CpG methyl acceptor site and an 80% depletion in its frequency of occurrence in vertebrate DNA. The coding regions of many genes contain CpGs which are methylated in sperm and serve as hot spots for mutation in human genetic diseases. Fully 30–40% of all human germline point mutations are thought to be methylation induced even though the CpG dinucleotide is (...) under‐represented and efficient cellular repair systems exist. Importantly, tumor suppressor genes such as p53 also contain methylated CpGs and these serve as hot spots for mutations in some, but not all, human cancers. Comparison of the spectrum of mutations present in this gene in different human cancers allows for predictions to be made on the molecular mechanisms of tumorigenesis. (shrink)

Multiculturalism is higher on the daily political agenda than it has ever been. Leading politicians and public commentators speak with an unparalleled bluntness about the perceived limitations of multiculturalism while representatives of cultural, minorities express concern about marginalisation. This debate is taking place against a background of fear about terrorism, the integrity of national identities and a loosely construed ‘clash of civilizations’. Secularism is pitted against religious fundamentalism, respect for difference against the right of freedom of speech, integration against self-determination, (...) and duties of citizenship against minority rights. This book confronts the reality of moral conflict in the debate on multiculturalism while resisting the simplification which too frequently accompanies daily commentary on both sides of an increasingly polarised debate. The volume as a whole marks an important step in the attempt to examine the underlying concepts, of the nature and legitimate extent of disagreement, of secularism, the nature of power, the state and citizenship, which inevitably constitute key assumptions in the debate. Bringing together leading scholars on multiculturalism: Gerald Gaus, Peter Jones, John Horton, Tariq Modood, Chandran Kukathas, Bhikhu Parekh, Matthew Festenstein and Cecile Laborde, this book discusses the latest developments in the field. It will be of strong interest students and scholars of multiculturalism, political science, political theory, international relations, sociology, philosophy and anthropology. (shrink)

This interdisciplinary collection of essays highlights the relevance of Buddhist doctrine and practice to issues of globalization. From philosophical, religious, historical, and political perspectives, the authors show that Buddhism—arguably the world’s first transnational religion—is a rich resource for navigating todays interconnected world.

Pioneering work in the 1940s and 1950s suggested that the concept of chunking might be important in many processes of perception, learning and cognition in humans and animals. We summarize here the major sources of evidence for chunking mechanisms, and consider how such mechanisms have been implemented in computational models of the learning process. We distinguish two forms of chunking: the first deliberate, under strategic control, and goal-oriented; the second automatic, continuous, and linked to perceptual processes. Recent work with discrimination-network (...) computational models of long- and short-term memory (EPAM/CHREST) has produced a diverse range of applications of perceptual chunking. We focus on recent successes in verbal learning, expert memory, language acquisition and learning multiple representations, to illustrate the implementation and use of chunking mechanisms within contemporary models of human learning.

ABSTRACT:A wide range of research uses patterns of genetic variation to infer genetic similarity between individuals, typically referred to as genetic ancestry. This research includes inference of human demographic history, understanding the genetic architecture of traits, and predicting disease risk. Researchers are not just structuring an intellectual inquiry when using genetic ancestry, they are also creating analytical frameworks with broader societal ramifications. This essay presents an ethics framework in the spirit of virtue ethics for these researchers: rather than focus on (...) rule following, the framework is designed to build researchers’ capacities to react to the ethical dimensions of their work. The authors identify one overarching principle of intellectual freedom and responsibility, noting that freedom in all its guises comes with responsibility, and they identify and define four principles that collectively uphold researchers’ intellectual responsibility: truthfulness, justice and fairness, anti-racism, and public beneficence. Researchers should bring their practices into alignment with these principles, and to aid this, the authors name three common ways research practices infringe these principles, suggest a step-by-step process for aligning research choices with the principles, provide rules of thumb for achieving alignment, and give a worked case. The essay concludes by identifying support needed by researchers to act in accord with the proposed framework. (shrink)

The relationship of part to whole is one of the most fundamental there is; this is the first and only full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology.

'Parts could easily be the standard book on mereology for the next (...) twenty or thirty years.' Timothy Williamson, Grazer Philosophische Studien. (shrink)

I reply to each of the contributions in this issue. I agree with much that Hillel Steiner argues, especially his insistence that the associated ideas of impartiality and discontinuity are crucial to dealing satisfactorily with a diversity of competing claims. I am, however, less willing to conceive provision for that diversity as the role, rather than a role, that we should ascribe to rights. I question the success of David Miller’s endeavour to provide a unified justification of human rights grounded (...) in the concept of need. It is the notion of a minimally decent human life, rather than need itself, that does most of the justificatory work in Miller’s argument and, arguably, that notion does not deliver a genuinely unitary account of human rights. I concede the case for state funding of opera and the arts more generally to John Horton’s argument, but defend neutralism, and its associated distinction between the right and the good, as a strategy for dealing with diversity, including cultural diversity. I resist Richard Bellamy’s attempt to ground all basic rights in democracy and suggest that his argument relies upon idealized assumptions about the functioning of democracy. I share much of his objection to substituting judicial for political decision-making but argue that a strong moral commitment to rights need not imply a shift in power from democratic processes to courts. I endorse Albert Weale’s argument for favouring a beneficial design approach over a rights approach to healthcare and to many other social goods. Rights should not monopolize our moral and political thinking. (shrink)

The relationship of part to whole is one of the most fundamental there is, yet until now there has been no full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology. Peter Simons surveys and criticizes previous theories, especially the standard extensional view, and proposes a more adequate account which encompasses both temporal and modal considerations in detail. This has far-reaching consequences for our understanding of such classical philosophical (...) concepts as identity, individual, class, substance and accident, matter, form, essence, dependence, and integral whole. It also enables the author to offer new solutions to long-standing problems surrounding these concepts, such as the Ship of Theseus Problem and the issue of mereological essentialism. The author shows by his use of formal techniques that classical philosophical problems are amenable to rigorous treatment, and the book represents a synthesis of issues and methods from the analytical tradition and from the older continental realist tradition of Brentano and the early Husserl.

0. My aims in this paper are largely expository: I am more interested in presenting the picture theory than deciding its truth. Even so, I hope that the arguments by which I develop the theory will do something to support it, since I believe that what I will present as Wittgenstein's view is indeed the truth. This is not an admission of insanity, though some things that have been thought intrinsic to the picture theory are things it would be insane (...) to believe. So clearly the view I will present, when compared to the most embracing interpretations, is a partial and selective one. It would be another kind of madness, one I am just as eagre to disown, to suppose that my own favoured selection is the only possible one. That is pretty well the last remark in this paper about other commentators. I trust my reticence entitles me to be presumed catholic until proven nonconformist. (shrink)

There is increasing concern about “surveillance capitalism,” whereby for-profit companies generate value from data, while individuals are unable to resist (Zuboff 2019). Non-profits using data-enabled surveillance receive less attention. Higher education institutions (HEIs) have embraced data analytics, but the wide latitude that private, profit-oriented enterprises have to collect data is inappropriate. HEIs have a fiduciary relationship to students, not a narrowly transactional one (see Jones et al, forthcoming). They are responsible for facets of student life beyond education. In addition to (...) classrooms, learning management systems, and libraries, HEIs manage dormitories, gyms, dining halls, health facilities, career advising, police departments, and student employment. HEIs collect and use student data in all of these domains, ostensibly to understand learner behaviors and contexts, improve learning outcomes, and increase institutional efficiency through “learning analytics” (LA). ID card swipes and Wi-Fi log-ins can track student location, class attendance, use of campus facilities, eating habits, and friend groups. Course management systems capture how students interact with readings, video lectures, and discussion boards. Application materials provide demographic information. These data are used to identify students needing support, predict enrollment demands, and target recruiting efforts. These are laudable aims. However, current LA practices may be inconsistent with HEIs’ fiduciary responsibilities. HEIs often justify LA as advancing student interests, but some projects advance primarily organizational welfare and institutional interests. Moreover, LA advances a narrow conception of student interests while discounting privacy and autonomy. Students are generally unaware of the information collected, do not provide meaningful consent, and express discomfort and resigned acceptance about HEI data practices, especially for non-academic data (see Jones et al. forthcoming). The breadth and depth of student information available, combined with their fiduciary responsibility, create a duty that HEIs exercise substantial restraint and rigorous evaluation in data collection and use.

A vital step to successfully orienting Deleuze with biosemiotics (and theories of biological complexity overall) is to discover a coherent scientific throughline in his work that also accounts for the aesthetic/creative dimension of his philosophy. This requires the heterodox move (from a Deleuzean point of view) of giving priority to the organism. I argue that Deleuze’s treatment of the organism does more than signal a superficial relation to biological complexity theory that, as a result of his nuanced take on the (...) matter, undermines the value of the organic body to his system. Instead, we can recognize a working theory of autopoiesis in the early Deleuze that scaffolds as well as substantiates his later ethological and biosemiotic observations and reveals a definite, albeit minimal, notion of subjectivity in his work. Most importantly, reorienting his logic of sense as a logic of sense-making, or the context-dependent signification between system and environment (Thompson, 2007), allows us to begin the work of mining a scientific throughline in Deleuze’s work akin to biological complexity theory that is of value to both Deleuze studies and biosemiotics.

This paper is a review of work on Newman's objection to epistemic structural realism (ESR). In Section 2, a brief statement of ESR is provided. In Section 3, Newman's objection and its recent variants are outlined. In Section 4, two responses that argue that the objection can be evaded by abandoning the Ramsey-sentence approach to ESR are considered. In Section 5, three responses that have been put forward specifically to rescue the Ramsey-sentence approach to ESR from the modern versions of (...) the objection are discussed. Finally, in Section 6, three responses are considered that are neutral with respect to one's approach to ESR and all argue (in different ways) that the objection can be evaded by introducing the notion that some relations/structures are privileged over others. It is concluded that none of these suggestions is an adequate response to Newman's objection, which therefore remains a serious problem for ESRists.

Scientists have used models for hundreds of years as a means of describing phenomena and as a basis for further analogy. In Scientific Models in Philosophy of Science, Daniela Bailer-Jones assembles an original and comprehensive philosophical analysis of how models have been used and interpreted in both historical and contemporary contexts. Bailer-Jones delineates the many forms models can take (ranging from equations to animals; from physical objects to theoretical constructs), and how they are put to use. She examines early mechanical (...) models employed by nineteenth-century physicists such as Kelvin and Maxwell, describes their roots in the mathematical principles of Newton and others, and compares them to contemporary mechanistic approaches. Bailer-Jones then views the use of analogy in the late nineteenth century as a means of understanding models and to link different branches of science. She reveals how analogies can also be models themselves, or can help to create them. The first half of the twentieth century saw little mention of models in the literature of logical empiricism. Focusing primarily on theory, logical empiricists believed that models were of temporary importance, flawed, and awaiting correction. The later contesting of logical empiricism, particularly the hypothetico-deductive account of theories, by philosophers such as Mary Hesse, sparked a renewed interest in the importance of models during the 1950s that continues to this day. Bailer-Jones analyzes subsequent propositions of: models as metaphors; Kuhn's concept of a paradigm; the Semantic View of theories; and the case study approaches of Cartwright and Morrison, among others. She then engages current debates on topics such as phenomena versus data, the distinctions between models and theories, the concepts of representation and realism, and the discerning of falsities in models.

Scientific models represent aspects of the empirical world. I explore to what extent this representational relationship, given the specific properties of models, can be analysed in terms of propositions to which truth or falsity can be attributed. For example, models frequently entail false propositions despite the fact that they are intended to say something "truthful" about phenomena. I argue that the representational relationship is constituted by model users "agreeing" on the function of a model, on the fit with data and (...) on the aspects of a phenomenon that are modelled. Model users weigh the propositions entailed by a model and from this decide which of these propositions are crucial to the acceptance and continued use of the model. Thus, models represent phenomena when certain propositions they entail are true, but this alone does not exhaust the representational relationship. Therefore, the constraints that produce the choice of the relevant propositions in a model must also be examined and their analysis contributes to understanding the relationship between models and phenomena.

There are at least three things we might mean by "ethics in robotics": the ethical systems built into robots, the ethics of people who design and use robots, and the ethics of how people treat robots. This paper argues that the best approach to robot ethics is one which addresses all three of these, and to do this it ought to consider robots as socio-technical systems. By so doing, it is possible to think of a continuum of agency that lies (...) between amoral and fully autonomous moral agents. Thus, robots might move gradually along this continuum as they acquire greater capabilities and ethical sophistication. It also argues that many of the issues regarding the distribution of responsibility in complex socio-technical systems might best be addressed by looking to legal theory, rather than moral theory. This is because our overarching interest in robot ethics ought to be the practical one of preventing robots from doing harm, as well as preventing humans from unjustly avoiding responsibility for their actions.

In recent years there has been much debate over whether recognition has displaced, or should displace, redistribution as the pre‐eminent concern of contemporary politics. That debate is not about whether we should continue to pursue an egalitarian ideal, since equality is as much a goal for the politics of recognition as it is for the politics of redistribution. In this essay, I address only issues of recognition and ask what kind of equal recognition we can reasonably demand or pursue. I (...) argue that we can expect to secure equal recognition of difference or particularity only if that recognition is mediated by more general forms of recognition. Certainly that approach is implied if we hold that difference should be recognised because that difference matters to the recognised rather than to the recogniser. Thus, I challenge the prevailing view that the politics of difference should replace the politics of universalism; rather, the politics of difference presupposes a form of universalism. I also use a distinction between status and merit recognition to indicate the difficulties that confront the goal of equal recognition if we insist that particularity or difference should be the object of unmediated recognition. I use cultural and religious identities as the main foci for my argument, but I also consider how far that argument translates to issues of sexuality and gender. (shrink)

Although the relationship of part to whole is one of the most fundamental there is, this is the first full-length study of this key concept. Showing that mereology, or the formal theory of part and whole, is essential to ontology, Simons surveys and critiques previous theories--especially the standard extensional view--and proposes a new account that encompasses both temporal and modal considerations. Simons's revised theory not only allows him to offer fresh solutions to long-standing problems, but also has far-reaching consequences for (...) our understanding of a host of classical philosophical concepts.

The paper examines important discrepancies between major figures influencing the intellectual development of biosemiotics. It takes its perspective from the work of Gregory Bateson. Unlike C. S. Peirce and J. von Uexküll, Bateson begins with a strong notion of interaction. His early writings were about reciprocity and social exchange, a common topic among anthropologists of the time, but Bateson’s approach was unique. He developed the notion of meta-patterns of exchange, and of the “abduction” of these metapatterns to a variety of (...) other phenomena, in both biology and in game theory. Later, Bateson’s concept of ecology of mind, the product of interactive phenomena, was modified by a non-purposive cybernetics. Biosemiotics has yet to adopt Bateson’s interactive stance, which is absent from Peirce’s approach to communication, of Uexküll’s functional cycles, and of Hoffmeyer’s discussion of the relation between culture and environment. Rather than pursuing notions of appropriate “subjectivity” through changed ethical response to ecological conditions (Hoffmeyer’s discussion of empathy), the paper discusses the advantages of an approach that continues to focus on conditions of paradox and pathology. Specifically, Bateson’s resolution of the relation between culture and environment arises from situations of blocked communication where ecological bonds become binds. (shrink)

The paper examines the sudden disappearance in the United States of millions of honeybees in managed bee colonies. The major research undertaken in the U.S. concentrates on finding the pathogens responsible. This paper suggests an alternative avenue of research a) that as a result of global warming there is a disjunction between bees pollinating cycles and the life cycle of plants b) that understanding changes in “timing cycles” as a result of global warming is the key to understanding the disappearance (...) of the bees. It notes that Gregory Bateson argued that any condition of ecosystem collapse would be characterized first by a collapse in its communicative order rather, than from changed physical states. The collapse of bee colonies and demise of other pollinators is a seeming confirmation of Gregory Bateson argument. Honeybees are ‘go betweens’ in ecosystemic order. It also argues that an appropriate topology of timing cycles and their recursions would enable better visual comprehension of the heterarchical ‘pattern which connects’, in Bateson’s phrase, and prompt awareness of possible catastrophe in human food supplies.
