The Protein Ontology (PRO) provides a formal, logically-based classification of specific protein classes including structured representations of protein isoforms, variants and modified forms. Initially focused on proteins found in human, mouse and Escherichia coli, PRO now includes representations of protein complexes. The PRO Consortium works in concert with the developers of other biomedical ontologies and protein knowledge bases to provide the ability to formally organize and integrate representations of precise protein forms so as to enhance accessibility to results of protein (...) research. PRO (http://pir.georgetown.edu/pro) is part of the Open Biomedical Ontologies (OBO) Foundry. (shrink)

There is a war between the ones who say there is a war and the ones who say there isn’t.argument: pluralistic theory opens itself toward different values, languages, histories, modes of reasoning, and forms of experience with a commitment not to reduce or hierarchize the many by means of the one. Such theory has emerged out of various traditions, including those associated with American pragmatism (Emerson, James, Dewey), analytic philosophy (Wittgenstein, Rorty), and continental philosophy (Derrida, Nancy). Not surprisingly, the pluralism (...) issuing from these traditions takes diverse forms and articulates itself through heterogeneous concepts and styles. Many pluralist philosophers in the present, however, have .. (shrink)

This essay investigates the way in which dying and dead bodies resist poetic incorporation and the way in which such bodies can be fugitively attested to through fictive prose. It examines Heidegger's treatment of dead and dying bodies from Being and Time to his later work on poetry and language, and it offers as a counterpoint another mode of addressing these bodies found in the fiction of Poe. It also shows how even the poetry of Trakl, heralded by Heidegger as (...) an exemplar of poetic address, can be fruitfully understood in prosaic terms, terms which more faithfully reveal both the content of his poetry itself as well as the true nature of the wounds of dying life.

In this article, I perform an aesthetic analysis of the intuition of phenomenal consciousness, redescribing this intuition as the result of a creative activity affirming of the uniqueness and value of human engagements with the world rather than the result of an activity of self-knowing through which phenomenal awareness becomes aware of itself. During this analysis, I analogize the construction of the intuition of phenomenal consciousness to the construction of religious intuitions for sophisticated believers and the construction of aesthetic intuitions (...) for sophisticated aesthetes. I find accounts of the 'mistake' of the intuition of phenomenal consciousness by authors such as Dennett are overly reductive and simplistic, even though I agree that phenomenal consciousness is a created illusion rather than a natural kind. The intuition of phenomenal consciousness is a sophisticated formation which testifies to the commitment of certain naturalistically inclined theorists to the inestimable value of private experience.

Many private business relationships are increasingly characterized by claims that certain actions should not be permitted since particular right claims are involved. Such claims should be taken seriously, but are they always ethically legitimate? This paper analyzes one context, the use of age as a rating variable in the pricing of automobile insurance, where such claims are made. By identifying, evaluating and assessing the relevant basis for the differentiation, actuarial equity, it is concluded that there is an ethical basis for (...) such a practice. The analysis also provides an equivalent means for considering other such analogous claims where actuarial equity is involved. (shrink)

Little is known about the biting nuisance of mosquitoes in the UK, despite the high numbers found in some locations. A telephone questionnaire survey was used to determine the perceived nuisance of biting insects on the Isle of Sheppey, Kent, a place notorious for mosquitoes. Two hundred randomly selected individuals were interviewed and asked if they suffered from mosquito bites. If they answered yes, they were asked to describe where and when they were bitten, and what measures they took against (...) mosquitoes. Forty-six per cent of respondents completed the questionnaire. Of those, 50% reported being bitten by mosquitoes, mostly outside during the summer. Seventy per cent said that most biting occurred during the evening and night. Of those respondents who protected themselves against biting (27), most used repellents (70%), with the remainder changing their behaviour to avoid mosquitoes, including closing or screening windows (33%), wearing thicker clothes (7%) and spraying insecticide (4%). One person slept under a bednet in summer (4%). This study provides evidence that on the Isle of Sheppey mosquitoes are considered a major nuisance by a sizeable proportion of the population. Since there is growing interest in the threat posed by new and emerging diseases in the UK, health authorities will need to make substantial efforts to inform and reassure the public about the threats posed by mosquitoes in areas where they are common.

The core goal of this study is to empirically investigate whether there is a “world price” of corporate sustainability. This is assessed in the context of standard asset pricing models—in particular, by asking whether a risk premium attaches to a sustainability factor after controlling for the Fama–French factors. Both time-series and cross-sectional tests are formulated and applied. The results show that (1) global Fama–French factors have strong power to explain global equity returns and (2) sustainability investments have no significant impact (...) on global equity returns. The absence of a significant relationship between sustainability and returns implies that large institutional investors are free to implement sustainability mandates without fear of breaching their fiduciary duties from realising negative returns due to incorporating a sustainability investment process.

Representing species-specific proteins and protein complexes in ontologies that are both human and machine-readable facilitates the retrieval, analysis, and interpretation of genome-scale data sets. Although existing protin-centric informatics resources provide the biomedical research community with well-curated compendia of protein sequence and structure, these resources lack formal ontological representations of the relationships among the proteins themselves. The Protein Ontology (PRO) Consortium is filling this informatics resource gap by developing ontological representations and relationships among proteins and their variants and modified forms. Because (...) proteins are often functional only as members of stable protein complexes, the PRO Consortium, in collaboration with existing protein and pathway databases, has launched a new initiative to implement logical and consistent representation of protein complexes. We describe here how the PRO Consortium is meeting the challenge of representing species-specific protein complexes, how protein complex representation in PRO supports annotation of protein complexes and comparative biology, and how PRO is being integrated into existing community bioinformatics resources. The PRO resource is accessible at http://pir.georgetown.edu/pro/. (shrink)

The current COVID-19 pandemic and the previous SARS/MERS outbreaks of 2003 and 2012 have resulted in a series of major global public health crises. We argue that in the interest of developing effective and safe vaccines and drugs and to better understand coronaviruses and associated disease mechenisms it is necessary to integrate the large and exponentially growing body of heterogeneous coronavirus data. Ontologies play an important role in standard-based knowledge and data representation, integration, sharing, and analysis. Accordingly, we initiated the (...) development of the community-based Coronavirus Infectious Disease Ontology in early 2020. -/- As an Open Biomedical Ontology (OBO) library ontology, CIDO is open source and interoperable with other existing OBO ontologies. CIDO is aligned with the Basic Formal Ontology and Viral Infectious Disease Ontology. CIDO has imported terms from over 30 OBO ontologies. For example, CIDO imports all SARS-CoV-2 protein terms from the Protein Ontology, COVID-19-related phenotype terms from the Human Phenotype Ontology, and over 100 COVID-19 terms for vaccines (both authorized and in clinical trial) from the Vaccine Ontology. CIDO systematically represents variants of SARS-CoV-2 viruses and over 300 amino acid substitutions therein, along with over 300 diagnostic kits and methods. CIDO also describes hundreds of host-coronavirus protein-protein interactions (PPIs) and the drugs that target proteins in these PPIs. CIDO has been used to model COVID-19 related phenomena in areas such as epidemiology. The scope of CIDO was evaluated by visual analysis supported by a summarization network method. CIDO has been used in various applications such as term standardization, inference, natural language processing (NLP) and clinical data integration. We have applied the amino acid variant knowledge present in CIDO to analyze differences between SARS-CoV-2 Delta and Omicron variants. CIDO's integrative host-coronavirus PPIs and drug-target knowledge has also been used to support drug repurposing for COVID-19 treatment. -/- CIDO represents entities and relations in the domain of coronavirus diseases with a special focus on COVID-19. It supports shared knowledge representation, data and metadata standardization and integration, and has been used in a range of applications. (shrink)

Robert Elliot claims that the metaethical distinction between subjectivism and objectivism is unimportant in environmental ethics. He argues that because a sufficiently sophisticated subjectivist can accommodate all the intrinsic value an objectivist can, even in apparently problematic situations where humans either do not exist or do not have the relevant values, and because metaethical commitments fail to have any normative or motivational impact on rational debate, it makes no difference whether an environmental ethicist is a subjectivist or an objectivist. (...) Elliot's dismissal, however, is unjustified. As it turns out, objectivists argue differently from the way subjectivists do, are motivated differently from the way subjectivists are, and are able to make a greater range of intrinsic value claims than subjectivists are. If Elliot's arguments have any appeal at all, it is only because he blurs the fundamental metaethical distinction in the first place and defends a subjectivism so objectivist that it is almost unrecognizable as subjectivism.

This paper looks at the centrality of action in social disciplines and examines the implications of this for whether social disciplines can be called scientific. Various reasons for calling social disciplines scientific are examined and rejected: (1) the claim that social disciplines are reducible to natural scientific ones, (2) the claim, from Donald Davidson, that reasons for action are to be construed in causal terms, (3) the claim that social disciplines employ, or should employ, the methodologies of the natural sciences. (...) The question of progress in social disciplines will also be examined critically. Does the (apparent) lack of progress in social disciplines suggest that academics working in sociology, economics, politics, human geography, and philosophy should adopt the methods of natural science? My answer will be that it does not but nonetheless I will side with John Dupré against Hutchinson, Read, and Sharrock in claiming that social disciplines can properly be called scientific. There is such a thing as a social science. (shrink)

I want to argue that in the modern world national cultures are distinctly different from one another, and although not homogeneous, are homogenizing: that is, each national society has a culture that, while allowing for difference, nonetheless presses in the direction of a single dominant profile. This is to put in more abstract terms the argument of Habits of the Heart that America has a first language, composed of two complementary aspects, utilitarian and expressive individualism, and also second languages, namely (...) biblical and civic Republican languages that have tended to get pushed to the margins.Already in the Introduction to the new paperback edition of Habits, my coauthors and I suggested that the individualism which is America's dominant cultural orientation was not solely derived from 18th century Utilitarianism and 19th century Romanticism, but had roots in both of our second languages as well. In my November, 1997, address to the American Academy of Religion, “Is There a Common American Culture?” I took the argument a step further, reaching almost to the point from which I want to start this paper. There I argued that beyond the homogenizing effect of television, education, and consumerism, and deeper even than utilitarian and expressive individualism, there was a still, small voice, a tiny seed, from which our current cultural orientation derives.Nestled in the very core of utilitarian and expressive individualism is something very deep, very genuine, very old, very American, something we did not quite see or say in Habits, and its core is religious. In Habits we quoted a famous passage in Toqueville's Democracy in America: “I think I can see the whole destiny of America contained in the first Puritan who landed on those shores.” Then we went on to name John Winthrop, following Tocqueville's own predilection, as the likeliest candidate for being that first Puritan. Now I am ready to admit, although regretfully, that we, and Tocqueville, were probably wrong. That first Puritan who contained our whole destiny might have been, as we also half intimated in Habits, Anne Hutchinson, but the stronger candidate, because we know so much more about him, is Roger Williams.

Hoping is an integral part of what it is to be human, and its significance for education has been widely noted. Hope is, however, a contested category of human experience and getting to grips with its characteristics and dynamics is a difficult task. The paper argues that hope is not a singular undifferentiated experience and is best understood as a socially mediated human capacity with varying affective, cognitive and behavioural dimensions. Drawing on the philosophy, theology and psychology of hope, five (...) modes of hoping are outlined: patient, critical, sound, resolute and transformative. The key aim of the paper is to illustrate how different modes of hoping are associated with different pedagogical strategies. Phrased differently, the paper seeks to delineate a range of pedagogies of hope. The phrase ‘pedagogy of hope’ is very much associated with critical theory—one thinks instantly of, for example, Paulo Freire, Henry Giroux or bell hooks. There are many pedagogies of hope, however, and an explicitly conservative text such as William Bennett’s Book of Virtues has as strong a claim to the title as Freire’s radical and utopian ideas. A broader argument, therefore, is that there is nothing inherently radical or subversive about a pedagogy of hope. Pedagogies of hope can serve to reproduce social relations as well as to transform them. (shrink)

This article makes the political dimension of Gadamer's thought more explicit by examining the interplay of three concepts in his work: solidarity, friendship, and the other. Focusing primarily on certain post--"Truth and Method" writings, I argue that Gadamer's conception of solidarity has to do with historically contingent manifestations of bonds that reflect a civic life together of reciprocal co-perception. These bonds go beyond conscious recognition of observable similarities and differences and emerge from encounters among those who are, and remain, in (...) important ways other to each other. I make this case through an analysis of Gadamer's phenomenology of friendship and the crucial role of otherness in his accounts of both understanding and friendship. I suggest that Gadamer's political thought gives us a way of conceptualizing solidarity and otherness without making the other same or leaving the other completely other. (shrink)

The best way to divide control over children’s education between private and state authorities is unclear. This task has ethical implications that this thesis explores—in the context of a pluralist liberal democracy. In cases where authority over children’s education is granted to private groups, like ethnic or religious minorities, rights are often part of the default vocabulary adopted by politically liberal commentaries. These rights are often viewed as a shield that offers the group immunity from state interference. Some illiberal minority (...) groups argue that they need to be shielded from state interference because the persistence of their cultural or religious identity depends on it. For example, the Amish community in Wisconsin argued in Wisconsin v. Yoder that the future of their community would be jeopardized if they were forced to send their children to school beyond the age of fourteen. While a rights-based approach does explain many of the variables connected with cases like these, the explanation is incomplete. I will offer two clarifications to the rights-based view. First, in the event that a minority group is shielded from state interference, it is not clear that it would be morally legitimate for the group to take over the authority of the state. I will, then, offer a plausible theory that could justify the self-governing authority of minority groups in these situations. My second clarification is that the concept of individual autonomy, often the central liberal value protected by rights, is too broad to support a zero-tolerance approach toward illiberal groups. This indicates that illiberal minority groups might still have a claim to self-governing authority even though they arguably interfere with the autonomy of their children. Some interference with minor elements of individual autonomy should arguably be tolerated in cases where the ruination or assimilation of the group’s unique culture or religion is at stake. (shrink)

The impressive variation amongst biological individuals generates many complexities in addressing the simple-sounding question what is a biological individual? A distinction between evolutionary and physiological individuals is useful in thinking about biological individuals, as is attention to the kinds of groups, such as superorganisms and species, that have sometimes been thought of as biological individuals. More fully understanding the conceptual space that biological individuals occupy also involves considering a range of other concepts, such as life, reproduction, and agency. There has (...) been a focus in some recent discussions by both philosophers and biologists on how evolutionary individuals are created and regulated, as well as continuing work on the evolution of individuality.

This is the first comprehensive study of the ethics of G. E. Moore, the most important English-speaking ethicist of the 20th century. Moore's ethical project, set out in his seminal text the Principia Ethica is to preserve common moral insight from skepticism and, in effect, persuade his readers to accept the objective character of goodness. Brian Hutchinson explores Moore's arguments in detail, showing Moore's ethical work to be much richer and more sophisticated than his critics have acknowledged.

A new translation and edition of Aristotle's Protrepticus (with critical comments on the fragments) -/- Welcome -/- The Protrepticus was an early work of Aristotle, written while he was still a member of Plato's Academy, but it soon became one of the most famous works in the whole history of philosophy. Unfortunately it was not directly copied in the middle ages and so did not survive in its own manuscript tradition. But substantial fragments of it have been preserved in several (...) works by Iamblichus of Chalcis, a third century A.D. neo-Pythagorean philosopher and educator. On the basis of a close study of Iamblichus' extensive use and excerption of Aristotle's Protrepticus, it is possible to reconstruct the backbone of the lost work, and then to flesh it out with the other surviving reports about the work from antiquity (for example in Alexander of Aphrodisias and other ancient commentators on Aristotle). It is also possible to identify several papyrus fragments of the work, and many references and literary allusions in later authors, especially Cicero, whose own lost dialogue Hortensius was a defense of philosophy modeleld on Aristotle's.

Whilst continuing racism is often invoked as evidence of the urgent need for Philosophy for Children, there is little in the current literature that addresses the topic. Drawing on Critical Race Theory and the related field of Critical Whiteness Studies , I argue that racism is deeply ingrained culturally in society, and best understood in the context of ‘Whiteness’. Following a CRT-informed analysis of two picturebooks that have been recommended as starting points for philosophical enquiry into multiculturalism, racism and diversity (...) – ‘Elmer’ and ‘Tusk Tusk’ by David McKee, I argue that whilst the use of stories with animals is commonly regarded as offering children the comfort of distance from emotionally challenging topics, this has the effect of separating racism from its temporal and spatial realities, which limits rather than enhances opportunities for engaging philosophically with it. I argue in favour of the practice of ‘reading against the text’ and consider the epistemological and practical obstacles to this practice drawing on my own experiences discussing race with P4C practitioners in the UK. I attempt to illustrate how the selection of recommended materials, combined with commonly held principles of P4C, make for a climate where a philosophical engagement with race and racism that considers the discourse of ‘Whiteness’ is highly unlikely to occur. This leads me to posit the idea of The Gated Community of Enquiry. (shrink)

ABSTRACT Hegel gave the bureaucracy a distinctively corporatist and collegiate structure and insulated it from legislative control. The close match between these features of the Philosophy or Right and the structure of the Prussian bureaucracy, which had been used by reformers to insulate progressive decisions from Junker resistance, suggests that Hegel, too, wanted the bureaucracy to spearhead reform within a hostile environment.

How do we access the authentic self in order to live fulfilling, meaningful lives? In straightforward terms, The Heart of the Matter: Gifts in Strange Wrapping Paper explains a simple but extraordinarily powerful technique called the See, Feel, Hear Challenge that enables people to easily gain entry into the storehouse of their subconscious core beliefs. In the process, it cracks the coded messages that those beliefs release in the form of disease, suffering, addictions, unhappy relationships, and victimized circumstances. Based in (...) the latest findings in neuroscience and neurocardiology, this book guides readers to an uncomplicated understanding of the astounding power of our emotions and how life automatically delivers experiences that trigger negative reactions that subconsciously impact us. These emotions form the foundation of core beliefs that create unhealthy attitudes and dis-ease patterns that keep us from experiencing the authentic, satisfying lives we desire. Using clear examples and true stories from clients, Dr. Weissman’s latest work demonstrates how we can release these stored emotions and their wisdom via the See, Feel, Hear Challenge. It then explains how to use this simple method to evoke feelings that positively impact the quantum field, remolding our bodies, minds, and everyday lives into purposeful expressions of inner joy and radiant well-being. Whether you’re dealing with addictions, dysfunctional relationships, or illness, or are focused on becoming an Olympic champion, The Heart of the Matter gives you a potent tool for positive change and transformation that you can use for the rest of your life.

Biomedical ontologies are emerging as critical tools in genomic and proteomic research where complex data in disparate resources need to be integrated. A number of ontologies exist that describe the properties that can be attributed to proteins; for example, protein functions are described by Gene Ontology, while human diseases are described by Disease Ontology. There is, however, a gap in the current set of ontologies—one that describes the protein entities themselves and their relationships. We have designed a PRotein Ontology (PRO) (...) to facilitate protein annotation and to guide new experiments. The components of PRO extend from the classification of proteins on the basis of evolutionary relationships to the representation of the multiple protein forms of a gene (products generated by genetic variation, alternative splicing, proteolytic cleavage, and other post-translational modification). PRO will allow the specification of relationships between PRO, GO and other OBO Foundry ontologies. Here we describe the initial development of PRO, illustrated using human proteins from the TGF-beta signaling pathway. (shrink)

Drawing on a passage from Ramsey's Truth and Probability, we formulate a simple, plausible constraint on evaluating the accuracy of credences: the Calibration Test. We show that any additive, continuous accuracy measure that passes the Calibration Test will be strictly proper. Strictly proper accuracy measures are known to support the touchstone results of accuracy-first epistemology, for example vindications of probabilism and conditionalization. We show that our use of Calibration is an improvement on previous such appeals by showing how it answers (...) or sidesteps problems that have been raised for previous work in this area. (shrink)

What if your peers tell you that you should disregard your perceptions? Worse, what if your peers tell you to disregard the testimony of your peers? How should we respond if we get evidence that seems to undermine our epistemic rules? Several philosophers have argued that some epistemic rules are indefeasible. I will argue that all epistemic rules are defeasible. The result is a kind of epistemic particularism, according to which there are no simple rules connecting descriptive and normative facts. (...) I will argue that this type of particularism is more plausible in epistemology than in ethics. The result is an unwieldy and possibly infinitely long epistemic rule — an Uber-rule. I will argue that the Uber-rule applies to all agents, but is still defeasible — one may get misleading evidence against it and rationally lower one’s credence in it. (shrink)

This is the first book to consider the increasing importance of Jean-Luc Nancy's work, which has influenced key thinkers such as Jacques Derrida. All his major works have been translated into English, yet until now little has been made available on his place in contemporary philosophy.

Providing new perspectives on the issues of sense, art and community, these essays make it impossible to approach philosophy without reference to the work Jean-Luc Nancy. (shrink)

Theological interpretation of the Bible is one of the most significant debates within theology today. Yet what exactly is theological reading? Darren Sarisky proposes that it requires identification of the reader via a theological anthropology; an understanding of the text as a collection of signs; and reading the text with a view toward engaging with what it says of transcendence. Accounts of theological reading do not often give explicit focus to the place of the reader, but this work seeks (...) to redress this neglect. Sarisky examines Augustine's approach to the Bible and how his theological insights into the reader and the text generate an aim for interpretation, which is fulfilled by fitting reading strategies. He also engages with Spinoza, showing that theological exegesis contrasts not with approaches that take history seriously, but with naturalistic approaches to reading. (shrink)

Criticism of orthodox models of prejudice reduction is particularly relevant for lesbians, gay men, and bisexuals, particularly when considering stage models of coming-out.

In this paper I argue that whether or not a computer can be built that passes the Turing test is a central question in the philosophy of mind.

Many who take a dismissive attitude towards metaphysics trace their view back to Carnap’s ‘Empiricism, Semantics and Ontology’. But the reason Carnap takes a dismissive attitude to metaphysics is a matter of controversy. I will argue that no reason is given in ‘Empiricism, Semantics and Ontology’, and this is because his reason for rejecting metaphysical debates was given in ‘Pseudo-Problems in Philosophy’. The argument there assumes verificationism, but I will argue that his argument survives the rejection of verificationism. The root (...) of his argument is the claim that metaphysical statements cannot be justified; the point is epistemic, not semantic. I will argue that this remains a powerful challenge to metaphysics that has yet to be adequately answered. (shrink)

Psychology has benefited from an enormous wealth of knowledge about processes of cognition in relation to how the brain organizes information. Within the categorization literature, this behavior is often explained through theories of memory construction called exemplar theory and prototype theory which are typically based on similarity or rule functions as explanations of how categories emerge. Although these theories work well at modeling highly controlled stimuli in laboratory settings, they often perform less well outside of these settings, such as explaining (...) the emergence of background knowledge processes. In order to explain background knowledge, we present a non-similarity-based post-Skinnerian theory of human language called Relational Frame Theory which is rooted in a philosophical world view called functional contextualism. This theory offers a very different interpretation of how categories emerge through the functions of behavior and through contextual cues, which may be of some benefit to existing categorization theories. Specifically, RFT may be able to offer a novel explanation of how background knowledge arises, and we provide some mathematical considerations in order to identify a formal model. Finally, we discuss much of this work within the broader context of general semantic knowledge and artificial intelligence research. (shrink)
