The greatest challenge for Cultural Selection Theory, which holds that Darwinian natural selection contributes to cultural evolution, lies is the paucity of evidence for structural mechanisms in cultural systems that are sufficient for adaptation by natural selection. In part, clarification is required with respect to the interaction between cultural systems and their purported selective environments. Edmonds, Hull, and others have argued that Cultural Selection Theory requires simple, conclusive, unambiguous case studies in order to meet this challenge. To this end, I (...) am employing the songs of the Rufous-collared Sparrow, which seem to exhibit cultural adaptations that minimize signal degradation relative to local environments (Handford, et al.). Specifically, the more forested the habitat, the more the tail end of the song resembles a whistle rather than a trill; yet, variation in song is uncorrelated with genetic variation. I explore the mechanisms responsible for these putative acoustic adaptations through a series of computer simulations. I modify the framework of Alexander and Skyrms’ ‘Bargaining with Neighbours’: this dynamic evolutionary game theoretic framework is well-suited for my investigation because the local interactions between agents provide a basis for modeling song transmission from adults to fledglings. In the simplest version of the model, each bird adopts one of two song types – trill or whistle – and sings that song type for the duration of its life. These song strategies are communicated to other birds in neighboring territories, which are arranged as a grid composed of two acoustic habitats (forest and field). Birds have a set probability of dying in each year, and deceased birds are succeeded by fledglings. The likelihood that a fledgling adopts a particular song type depends on (i) the popularity of a particular song-type among neighboring birds and (ii) the relative ‘audibility’ of each signal, which is a joint function of the habitat and song type of the signaling bird. The main point of this research is not to test this model, but to demonstrate that models of this type have the resources to meet the outstanding challenges in Cultural Selection Theory. The benefits of this research are threefold. First, it will lend much needed empirical support to Cultural Selection Theory by clarifying the nature of the interaction between culture and environment. Second, it will support Alexander and Skyrms’ work by providing a set of empirically testable consequences for their model. Finally, it will contribute to evolutionary theory by clarifying the scope and limits of adaptation by natural selection. (shrink)

In this brief, we argue that there is a diversity of ways in which humans (Homo sapiens) are ‘persons’ and there are no non-arbitrary conceptions of ‘personhood’ that can include all humans and exclude all nonhuman animals. To do so we describe and assess the four most prominent conceptions of ‘personhood’ that can be found in the rulings concerning Kiko and Tommy, with particular focus on the most recent decision, Nonhuman Rights Project, Inc v Lavery.

Although several philosophical approaches to shame emphasize the role of the ‘other’ this has attracted less attention from psychologists. The psychological construct of self-awareness does not adequately account for the shift in perspective that is involved in shame or embarrassment. This paper outlines a framework for the analysis of shame which emphasises the adoption of another perspective on the self. It proposes that shame is experienced when an individual recognises that an action can give rise to a negative interpretation by (...) others of core aspects of the self, even if he or she does not share that interpretation and there is no self-attribution of responsibility for any wrongdoing. The framework is applied to the analysis of two episodes from Elizabeth Gaskell’s novel, North and South. The character is described as experiencing intense shame, despite her belief that she has behaved properly, and this is accompanied by her preoccupation with how her behaviour can be interpreted by others.

The analytic/synthetic distinction looks simple. It is a distinction between two different kinds of sentence. Synthetic sentences are true in part because of the way the world is, and in part because of what they mean. Analytic sentences - like all bachelors are unmarried and triangles have three sides - are different. They are true in virtue of meaning, so no matter what the world is like, as long as the sentence means what it does, it will be true. -/- (...) This distinction seems powerful because analytic sentences seem to be knowable in a special way. One can know that all bachelors are unmarried, for example, just by thinking about what it means. But many twentieth-century philosophers, with Quine in the lead, argued that there were no analytic sentences, that the idea of analyticity didn't even make sense, and that the analytic/synthetic distinction was therefore an illusion. Others couldn't see how there could fail to be a distinction, however ingenious the arguments of Quine and his supporters. -/- But since the heyday of the debate, things have changed in the philosophy of language. Tools have been refined, confusions cleared up, and most significantly, many philosophers now accept a view of language - semantic externalism - on which it is possible to see how the distinction could fail. One might be tempted to think that ultimately the distinction has fallen for reasons other than those proposed in the original debate. -/- In Truth in Virtue of Meaning, Gillian Russell argues that it hasn't. Using the tools of contemporary philosophy of language, she outlines a view of analytic sentences which is compatible with semantic externalism and defends that view against the old Quinean arguments. She then goes on to draw out the surprising epistemological consequences of her approach. (shrink)

Gillian Brock develops a model of global justice that takes seriously the moral equality of all human beings notwithstanding their legitimate diverse identifications and affiliations. She addresses concerns about implementing global justice, showing how we can move from theory to feasible public policy that makes progress toward global justice.

Like other science, technology, engineering, and mathematics fields, ecological research needs ethics. Given the rapid pace of technological developments and social change, it is important for scientists to have the vocabulary and critical-thinking skills necessary to identify, analyze, and communicate the ethical issues generated by the research and practices within their fields of specialization. The goal of introducing ethics education for ecological researchers would be to promote a discipline in which scientists are willing and able to engage in ethical questions (...) and problem solving, even if they do so inadequately at first. Practicing ecologists ought to be able to identify and critically evaluate the ethical dimensions of their field studies because ecologists are at the forefront of important interfaces between humans and other-than-human organisms and natural systems. They are among the first to identify the impact of anthropogenic changes to the environments. Rapidly changing local and global environments mean that ecologists will be on the front line of any efforts to create a sustainable lifestyle for humans on this planet. (shrink)

By executive order, the US adopted an immigration policy that looks remarkably similar to a Muslim ban, and threatened to deport long-settled residents, such as the so-called Dreamers. Our defunct refugee system has not dealt adequately with increased refugee flows, forcing desperate people to undertake increasingly risky measures in efforts to reach safe havens. Meanwhile increased migration flows over recent years appear to have contributed to a rise in right-wing populism, apparently driving phenomena such as Brexit and Trumpism. In this (...) original and insightful book Gillian Brock offers answers and tools that assist us in evaluating current migration policy and in helping to determine which policies may be permissible and which are normatively indefensible. She offers a comprehensive framework for responding to the many challenges which have recently emerged, and for delivering justice for people on the move along with those affected by migration.

A barrier to entailment exists if you can't get conclusions of a certain kind from premises of another. One of the most famous barriers in philosophy is Hume's Law, which says that you can't get normative conclusions from descriptive premises, or in slogan form: you can't get an ought from an is. This barrier is highly controversial, and many famous counterexamples were proposed in the last century. But there are other barriers which function almost as philosophical platitudes: no Universal conclusions (...) from Particular premises, no Future conclusions from premises about the Past, and no claims that attribute Necessity from premises that merely tell us how things happen to be in the Actual world. Barriers to Entailment proposes a unified logical account of five barriers that have played important roles in philosophy, in the process showing how to diagnose proposed counterexamples and arguing that the case for Hume's Law is as strong as that for the platitudinous barriers. -/- The first two parts of the book employ techniques from formal logic, but present them in an accessible way, suitable for any reader with some background in first-order model theory (of the kind that might be taught in a first class in logic). Gillian Russell introduces tense, modal, indexical, and deontic formal logics, but always avoids unneeded complexity. Each barrier is connected to broader philosophical topics: universality, time, necessity, context-sensitivity, and normativity. Russell brings out under-recognised connections between the domains and lays the groundwork for further work at the intersections. -/- The last part of the book transposes the formal work to informal barrier theses in the philosophy of language, in the process doing new work on the concept of logical consequence, and providing new responses to proposed informal counterexamples to Hume's Law which employ hard-to-formalise tools from natural language, such as speech acts and thick normative expressions.

In Mourning Becomes the Law, Gillian Rose takes us beyond the impasse of post-modernism or 'despairing rationalism withour reason'. Arguing that the post-modern search for a 'new ethics' and ironic philosophy are incoherent, she breathes new life into the debates concerning power and domination, transcendence and eternity. Mourning Becomes the Law is the philosophical counterpart to Gillian Rose's highly acclaimed memoir Love's Work. She extends similar clarity and insight to discussions of architecture, cinema, painting and poetry, through which (...) relations between the formation of the individual and the theory of justice are connected. At the heart of this reconnection lies a reflection on the significance of the Holocaust and Judaism. Mourning Becomes the Law reinvents the classical analogy of the soul, the city and the sacred. It returns philosophy, Nietzsche's 'bestowing virtue', to the pulse of our intellectual and political culture. (shrink)

Many of the most skilled and educated citizens of developing countries choose to emigrate. How may those societies respond to these facts? May they ever legitimately prevent the emigration of their citizens? Gillian Brock and Michael Blake debate these questions, and offer distinct arguments about the morality of emigration.

Logical monists and pluralists disagree about how many correct logics there are; the monists say there is just one, the pluralists that there are more. Could it turn out that both are wrong, and that there is no logic at all?

In the thousand years from the end of the Roman Empire to the Renaissance and Reformation of the Sixteenth century the discussion of the great questions of philosophy and religion was intense. Does God exist? What is he like? What is the purpose of human life and how does God show concern for the future of mankind? This is an introduction to the debates which did more than anything else to transform the ancient into the modern world of thought.

This paper argues for the significance of Kaplan's logic LD in two ways: first, by looking at how logic got along before we had LD, and second, by using it to bring out the similarity between David Hume's thesis that one cannot deduce claims about the future on the basis of premises only about the past, and the so‐called "essentiality" of the indexical.

In this paper I ask what logical consequence is, and give an answer that is somewhat different from the usual ones. It isn’t clear why anyone would need a new approach to logical consequence, so I begin by explaining the work that I need the answer to do and why the standard conceptions aren’t adequate. Then I articulate a replacement view which is.

Questions about the relation between shame and embarrassment are often posed in discussion of emotion but have rarely been examined at length. In this study I assemble and examine distinctions that have been proposed in the literature with the aim of identifying the criteria that have been used to differentiate shame and embarrassment. Relevant empirical studies are also reviewed. Despite the attention paid to the question of the difference between shame and embarrassment consensus on differentiating criteria has not been reached (...) nor has there been consideration of what kind of question is being posed. Three positions that have been adopted are identified and critically evaluated. (shrink)

We argue that the ecological research community should develop a plan for improving the ethical consistency and moral robustness of the field. We propose a particular ethics strategy—specifically, an ongoing process of collective ethical reflection that the community of ecological researchers, with the cooperation of applied ethicists and philosophers of biology, can use to address the needs we identify. We suggest a particular set of conceptual and analytic tools that, we argue, collectively have the resources to provide an empirically grounded (...) and conceptually complete foundation for an ethics strategy for ecological research. We illustrate our argument with information gathered from a survey of ecologists conducted at the 2013 meeting of the Canadian Society of Ecology and Evolution. (shrink)

ABSTRACT This paper argues for a version of sceptical invariantism about knowledge on which the acceptability of knowledge-attributing sentences varies with the context of assessment.

This paper proves a precisification of Hume’s Law—the thesis that one cannot get an ought from an is—as an instance of a more general theorem which establishes several other philosophically interesting, though less controversial, barriers to logical consequence.

The Broken Middle offers a startlingly original rethinking of the modern philosophical tradition and fundamentally rejects the anti-philosophy and anti-theory of post-modernity. Extending across the disciplines from philosophy to theology, Judaica, law, social and political theory, literary criticism, feminism and architecture, this book stakes itself on a renewed potential for sustained critique. Against the grain of much contemporary thought, this work of criticism offers the reader a way beyond the spurious alternatives of "totalization" or acknowledgement of the "other". The Broken (...) Middle expounds the phenomenology of the diremption of law and ethics. By reconstructing the suppressed political history of modernity, it shows that contemporary thought belongs to a tradition which has become ancient. Following this drama in the configuration of anxiety of beginning, equivocation of the ethical, and agon of authorship, the logos opens out of the pathos of the concept. (shrink)

One of the areas of concern raised by cross-border reproductive travel regards the treatment of women who are solicited to provide their ova or surrogacy services to foreign consumers. This is particularly troublesome in the context of developing countries where endemic poverty and low standards for both medical care and informed consent may place these women at risk of exploitation and harm. We explore two contrasting proposals for policy development regarding the industry, both of which seek to promote ethical outcomes (...) and social justice: While one proposal advocates efforts to minimize cross-border demand for female reproductive resources through the pursuit of national self-sufficiency, the other defends cross-border trade as a means for meeting the needs of vulnerable groups. Despite the conflicting objectives of the proposed strategies, the paper identifies common values and points of agreement between the two, including the importance of regulations to safeguard those providing ova or surrogacy services.

Recent work on analyticity distinguishes two kinds, metaphysical and epistemic. This paper argues that the distinction allows for a new view in the philosophy of logic according to which the claims of logic are metaphysically analytic and have distinctive modal profiles, even though their epistemology is holist and in many ways rather Quinean. It is argued that such a view combines some of the more attractive aspects of the Carnapian and Quinean approaches to logic, whilst avoiding some famous problems.

Hidalgo1 argues that, contrary to widespread belief, active recruitment of health workers ‘generally refrains from enabling harm or facilitating wrongdoing’. In this commentary, I argue that the case is not yet convincing. There are a number of problems with the argument, only some of which I can sketch here. These include: Hidalgo gives an insufficient account of the relevant harms that are inflicted when healthcare workers emigrate. Relatedly, he does not take account of the underlying causes of migration and what (...) might assist in remedying the situation. He thus fails to catalogue a wide range of losses that are born when health workers emigrate from developing countries and fails to appreciate how his recommendations undermine some of the constructive initiatives that might assist poor, developing countries. Hidalgo misrepresents the situation in developing countries, incorrectly describing government funding of tertiary education as some kind of gift, rather than an investment in creating important human capital to provide for citizens’ needs, which can mean that fair returns on investment are quite justified. With the correct descriptions in place, the grounding for various duties to reciprocate is rendered secure. There are some important problems with the empirical studies cited such that they do not provide support for Hidalgo's argument.I begin with the case for . There are large disparities in life prospects between developing and developed countries. Indeed, this wide disparity is one of the main reasons healthcare workers want to leave in the first place. If that is the main reason healthcare workers seek to exit, it is not insignificant what would address the causal, underlying problems. How do we promote prosperity in developing countries? A lively debate on this topic flourishes. However, one factor that has widespread support from all sides of the debate is that the quality of …. (shrink)

This paper is about the putative theoretical virtue of strength, as it might be used in abductive arguments to the correct logic in the epistemology of logic. It argues for three theses. The first is that the well-defined property of logical strength is neither a virtue nor a vice, so that logically weaker theories are not—all other things being equal—worse or better theories than logically stronger ones. The second thesis is that logical strength does not entail the looser characteristic of (...) scientific strength, and the third is that many modern logics are on a par—or can be made to be on a par—with respect to scientific strength.

Take a correct sequent of formal logic, perhaps a simple logical truth, like the law of excluded middle, or something with premises, like disjunctive syllogism, but basically a claim of the form \.Γ can be empty. If you don’t like my examples, feel free to choose your own, everything I have to say should apply to those as well. Such a sequent attributes the properties of logical truth or logical consequence to a schematic sentence or argument. This paper aims to (...) answer the question of how beliefs in such attributions are justified, on both its descriptive and normative interpretations; I aim to say when we generally take ourselves to be justified in forming such beliefs, and to make it plausible that beliefs formed this way really are justified.We can ask such questions about many domains but there are special difficulties for answering them in logic. Some of the difficulties stem from the fact that logic is thought t.. (shrink)

My target in this paper is a view that has sometimes been called the ‘ Linguistic Doctrine of Necessary Truth ’ and sometimes ‘Conventionalism about Necessity’. It is the view that necessity is grounded in the meanings of our expressions—meanings which are sometimes identified with the conventions governing those expressions—and that our knowledge of that necessity is based on our knowledge of those meanings or conventions. In its simplest form the view states that a truth, if it is necessary, is (...) necessary because it is analytic. It is widely recognized that this simple version of the view faces a prima facie problem with the existence of the necessary a posteriori. Assuming that all analytic truths are a priori, if there are necessary a posteriori truths then there are necessary synthetic truths—contradicting the view’s claim that all necessary truths are analytic. Contemporary L-DONTers have things to say about the problem, but in this paper I want to suggest that there is a different, more serious, problem which arises from the phenomenon of indexicality, which L-DONTers have not taken account of. Though there are many versions of the problem, a simple one is this. Consider Kaplan’s celebrated sentence. (shrink)

A review essay of Gillian Brock Global Justice: A Cosmopolitan Account (Oxford University Press, 2009).

This is a paper about the constituents of arguments. It argues that several different kinds of truth-bearer may be taken to compose arguments, but that none of the obvious candidates—sentences, propositions, sentence/truth-value pairs etc.—make sense of logic as it is actually practiced. The paper goes on to argue that by answering the question in different ways, we can generate different logics, thus ensuring a kind of logical pluralism that is different from that of J. Beall and Greg Restall.

Several ant species are known with genetic effects on caste determination but, for termites, the role of environment has been assumed to be omnipotent. Now Hayashi et al. report that commitment to the nymph and worker pathways in Reticulitermes speratus follows a simple model involving two alleles at a sex‐linked locus.1 The spread of this system of genetic caste determination seems best explained by selection at the colony level. This remarkable system may be widely applicable throughout termites, although it cannot (...) be universal, and may provide a window into causal aspects of the molecular biology of caste determination.

This article examines the contributions made towards eugenic thought in the late nineteenth and early twentieth centuries by Havelock Ellis . Ellis was a significant social reformer who worked on the problems of sexuality from a scientific–naturalist secular perspective. In the later phases of his work, after he had completed much of his writing on sexuality, Ellis concentrated on issues of feminism and eugenics—problems he thought were interlinked. In this paper, I integrate his ideas about these subjects, and consider the (...) ways in which Ellis and other liberal social reformers created a ‘eugenic subject’ in order to frame their arguments about social problems.
