We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

Cushman argues that the function of rationalization is to attribute mental representations to ourselves, thereby making these representations available for future planning. I argue that such attribution is often not necessary and sometimes maladaptive. I suggest a different explanation of rationalization: making representations available to other agents, to facilitate cooperation, transmission, and the ratchet effect that underlies cumulative cultural evolution.

Although there has been some growing recognition of the role of private actors in international environmental regimes, little attention has been paid to the role of the private sector at the science–policy interface. Because the automobile industry plays a crucial role in mitigation of greenhouse gases, successful policy requires not just the assent but the active cooperation of this sector. Such cooperation, however, requires some institutional acceptance that climate change is indeed a significant risk. In this article, the authors look (...) at the early stages of the automobile industry’s engagement with the discourse on climate change. The authors focus, in particular, on the role of corporate scientists in two U.S. automobile companies in translating this discourse. Acting as boundary spanners and institutional entrepreneurs, these individuals influenced both corporate perceptions of and responses to climate change science. (shrink)

Whereas many evolutionary models emphasize within-group cooperation or between-group competition in explaining human large-scale cooperation, recent work highlights a critical role for intergroup cooperation in human adaptation. Here we investigate intergroup cooperation in the domain of shotgun hunting in northern Republic of the Congo. In the Congo Basin broadly, forest foragers maintain relationships with neighboring farmers based on systems of exchange regulated by norms and institutions such as fictive kinship. In this study, we examine how relationships between Yambe farmers and (...) BaYaka foragers support stable intergroup cooperation in the domain of shotgun hunting. In the study village, shotgun hunting is based on a specialization-based exchange wherein Yambe farmers contribute shotguns and access to markets to buy cartridges and sell meat while BaYaka foragers contribute their specialized forest knowledge and skill. To understand how costs and benefits are distributed, we conducted structured interviews with 77 BaYaka hunters and 15 Yambe gun owners and accompanied hunters on nine hunting trips. We found that hunts are organized in a conventional manner within a fictive kinship structure, consistent with the presence of intercultural mechanisms to stabilize cooperation. However, because bushmeat demand is high, gun owners can gain significant cash profit, while compensating hunters only with cigarettes, alcohol, and a traditional hunter’s portion of meat. To level payoffs, hunters strategically hide kills or cartridges from gun owners to feed their own families. Our results illustrate how each group prioritizes different currencies (e.g., cash, meat, family, intergroup relations) and provide insights into how intergroup cooperation is stabilized in this setting. The example of this long-standing intergroup cooperative system is discussed in terms of its contemporary entwinement with logging, the bushmeat trade, and growing market intersection. (shrink)

Fair Trade coffee campaigns have improved the lives of small-scale coffee farmers and their families by raising wages, creating direct trade links to farming cooperatives, and providing access to affordable credit and technological assistance. Consumer demand for Fair Trade certified coffee is at an all-time high, yet cooperatives that produce it are only able to sell about half of their crops at the established fair trade price. This article explores the reasons behind this gap between supply and demand and suggests (...) ways to close it. The authors also offer some perspective on the limits of ethical consumption campaigns such as Fair Trade coffee. (shrink)

Punishment as a response to impairment of individual or group welfare may be found not only among humans but also among a wide range of social animals. In some cases, acts of punishment serve to increase social cooperation among conspecifics. Such phenomena motivate the search for the biological foundations of punishment among humans. Of special interest are cases of pro-social punishment of individuals harming others. Behavioral studies have shown that in economic games people punish exploiters even at a cost to (...) their own welfare. Additionally, neuroimaging studies have reported activity during the planning of such punishment in brain areas involved in the anticipation of reward. Such findings hint that there is an evolutionarily honed basic drive to punish social offenders. I argue that the transfer of punishment authority from the individual to the group requires that social offenders be punished as a public good, even if such punishment is not effective as retribution or deterrent. Furthermore, the social need for punishment of offenders has implications for alternatives to incarceration, publicity of punishment, and judicial structure. (shrink)

From the Greek satyr to the American Mickey Mouse and from the Chinese dragon to the Egyptian Sphinx, animals and animal/humans have come throughhuman imagination into myth, legend and story. This combination or fusion of animal and human in literature presents a double signification. At the same time that our attention goes to the animality of the human, we may also entertain the humanity of the animal. Besides blending of physical and psychological characteristics, these ancient and modern characters of world (...) texts may embed authentic experiences of communion or communication between humans and animals. The texts may be understood as signifying the limits of both the human and the animal and the possibility of the humanimal. Humanimality signifies the fusion of human and animal which dissolves the ordinary dualism of human subject and animal object and allows for intersubjectivity unmarked by specific biological limitations. This kind of intersubjectivity occurs in the contact of communication and is often an occasion for awe on the part of the human if not of the animal. We may understand such awesome communication as imitation, non-verbal cooperation, and as teaching and learning. Three poems by the author, reproduced in the Appendix, “The Ravens Fly Yet,” “Neighbors,” and “The Lesson,” provide the literary fields in which humanimal phenomena may appear. (shrink)

So‐called downshifters seek more meaningful lives by decreasing the amount of time they devote to work, leaving more time for the valuable goods of friendship, family and personal development. But though these are indeed meaning‐conferring activities, they do not have the right structure to count as superlatively meaningful. Only in work – of a certain kind – can superlative meaning be found. It is by active engagements in projects, which are activities of the right structure, dedicated to the achievement of (...) goods beyond ourselves, that we make our lives superlatively meaningful.

The external world sceptic tells some familiar narratives involving massive deception. Perhaps we are brains in vats. Perhaps we are the victim of a deceitful demon. You know the drill. The sceptic proceeds by observing first that victims of such deceptions know nothing about their external environment and that second, since we cannot rule out being a victim of such deceptions our- selves, our own external world beliefs fail to attain the status of knowledge. Discussions of global external world scepticism (...) tend to focus on the second step, where a number of well-known lines of resistance have been offered. But there has been little attention to the first, seemingly innocuous step. That will be the focus of this paper. Part one – sections 1, 2, and 3 – will explain why these standard narratives are not convincing examples of cases where there is no knowledge of the external world. In part two – section 4 – we shall undertake a useful case study. David Lewis’s ‘Elusive Knowledge’ is often thought of as presenting an epistemological vision that is somewhat friendly to external world scepticism: as Lewis himself presents things, there are contexts where external world knowledge ascriptions are uniformly false, and where true knowledge ascriptions are limited to either axiomatic truths or truths about our inner life. We examine his discussion in the light of the preceding reflections and show that the framework he presents is not so concessionary to global external world scepticism after all. (shrink)

We are constantly called upon to evaluate the evidential weight of testimony, and to balance its deliverances against our own independent thinking. ‘Intellectual autonomy’ is the virtue that is supposed to be displayed by those who engage in cognition in this domain well. I argue that this is at best a misleading label for the virtue, because virtuous cognition in this domain consists in thinking with others, and intelligently responding to testimony. I argue that the existing label supports an excessively (...) individualistic conception of good thinking, both within and outside philosophy. I propose replacing ‘intellectual autonomy’ with ‘intellectual interdependence’, which properly emphasises the depth of our reliance on one another, without suggesting we ought ever to be epistemically servile.

How does valuing something for its own sake differ from valuing an entity for the sake of other things? Although numerous answers come to mind, many of them rule out substantive views about what is valuable for its own sake. I therefore seek to provide a more neutral way to distinguish the two valuing attitudes. Drawing from existing accounts of valuing, I argue that the two can be distinguished in terms of a conative-volitional feature. Focusing first on “non-final valuing”—i.e. valuing_ (...) x_ for the sake of something else—I argue that it involves adopting certain reasons on account of a desire for _x_ to contribute to other things. I then show how this contrasts final valuing. The result, I argue, is a plausible account of how the two modes of valuing differ that leaves open substantive views about what all can be valued for its own sake. This is helpful because it develops a popular methodology used to explore the value of a wide range of things, including natural entities, family heirlooms, and artworks, as well as, more broadly, entities that might have “extrinsic final value.”.

Continental philosophy has entered a new period of ferment. The long deconstructionist era was followed with a period dominated by Deleuze, which has in turn evolved into a new situation still difficult to define. However, one common thread running through the new brand of continental positions is a renewed attention to materialist and realist options in philosophy. Among the leaders of the established generation, this new focus takes numerous forms. It might be hard to find many shared positions in the (...) writings of Badiou, DeLanda, Laruelle, Latour, Stengers, and Žižek, but what is missing from their positions is an obsession with the critique of written texts. All of them elaborate a positive ontology, despite the incompatibility of their results. Meanwhile, the new generation of continental thinkers is pushing these trends still further, as seen in currents ranging from transcendental materialism to the London-based speculative realism movement to new revivals of Derrida. As indicated by the title The Speculative Turn, the new currents of continental philosophy depart from the text-centered hermeneutic models of the past and engage in daring speculations about the nature of reality itself. This anthology assembles authors, of several generations and numerous nationalities, who will be at the centre of debate in continental philosophy for decades to come. (shrink)

Whatever its implications for the other features of human agency at its best — for moral responsibility, reasons-responsiveness, self-realization, flourishing, and so on—addiction is universally recognized as impairing autonomy. But philosophers have frequently misunderstood the nature of addiction, and therefore have not adequately explained the manner in which it impairs autonomy. Once we recognize that addiction is not incompatible with choice or volition, it becomes clear that none of the Standard accounts of autonomy can satisfactorily explain the way in which (...) it undermines fully autonomous agency. In order to understand to what extent and in what ways the addicted are autonomy-impaired, we need to understand autonomy as consisting, essentially, in the exercise of the capacity forextended agency.It is because addiction undermines extended agency, so that addicts are not able to integrate their lives and pursue a Single conception of the good, that it impairs autonomy.

From one end of his philosophical work to the other, Gilles Deleuze consistently described his position as a transcendental empiricism. But just what is transcendental about Deleuze’s transcendental empiricism? And how does his position fit with the traditional empiricism articulated by Hume? In Difference and Givenness , Levi Bryant addresses these long-neglected questions so critical to an understanding of Deleuze’s thinking. Through a close examination of Deleuze’s independent work--focusing especially on Difference and Repetition-- as well as his engagement with (...) thinkers such as Kant, Mai;mon, Bergson, and Simondon, Bryant sets out to unearth Deleuze’s transcendental empiricism and to show how it differs from transcendental idealism, absolute idealism, and traditional empiricism. What emerges from these efforts is a metaphysics that strives to articulate the conditions for real existence, capable of accounting for the individual itself without falling into conceptual or essentialist abstraction. In Bryant’s analysis, Deleuze’s metaphysics articulates an account of being as process or creative individuation based on difference, as well as a challenging critique--and explanation--of essentialist substance ontologies. A clear and powerful discussion of how Deleuze’s project relates to two of the most influential strains in the history of philosophy, this book will prove essential to anyone seeking to understand Deleuze’s thought and its specific contribution to metaphysics and epistemology.

Since Kant, philosophy has been obsessed with epistemological questions pertaining to the relationship between mind and world and human access to objects. In The Democracy of Objects Bryant proposes that we break with this tradition and once again initiate the project of ontology as first philosophy. Drawing on the object-oriented ontology of Graham Harman, as well as the thought Roy Bhaskar, Gilles Deleuze, Niklas Luhman, Aristotle, Jacques Lacan, Bruno Latour and the developmental systems theorists, Bryant develops a realist ontology that (...) he calls “onticology”. This ontology argues that being is composed entirely of objects, properties, and relations such that subjects themselves are a variant of objects. By way of systems theory and cybernetics, Bryant argues that objects are dynamic systems that relate to the world under conditions of operational closure. In this way, he integrates the most vital discoveries of the anti-realists within a realist ontology that does justice to both the material and cultural. Onticology proposes a flat ontology where objects of all sorts and at different scales equally exist without being reducible to other objects and where there are no transcendent entities such as eternal essences outside of dynamic interactions among objects. This work will be of great interest to Continental philosophers, ecologists, cultural theorists, media theorists, and those following recent developments in the thought of speculative realists.

In The Enterprise of Knowledge, I proposed a general theory of rational choice which I intended as a characterization of a prescriptive theory of ideal rationality. A cardinal tenet of this theory is that assessments of expected value or expected utility in the Bayesian sense may not be representable by a numerical indicator or indeed induce an ordering of feasible options in a context of deliberation. My reasons for taking this position are related to my commitment to the inquiry-oriented approach (...) to human knowledge and valuation favored by the American pragmatists, Charles Peirce and John Dewey. A feature of any acceptable view of inquiry ought to be that during an inquiry points under dispute ought to be kept in suspense pending resolution through inquiry. (shrink)

Defends and transforms naturalism and materialism to show how culture itself is formed by nature. Bryant endorses a pan-ecological theory of being, arguing that societies are ecosystems that can only be understood by considering nonhuman material agencies such as rivers and mountain ranges alongside signifying agencies such as discourses, narratives and ideologies.

Thinking about God is historical thinking and that in two senses : the idea of God has a history, and those who think about God think through an historically formed mind. The task of the theologian, is not the attempt to move outside his historicity - such an attempt constitutes a fallacy and not a virtue - but to accept its implications and limitations. Methodologically this means that the theologian must point to the historical perspectives that underlie the idea of (...) God in its development and, in his own constructive thought, must work self-consciously with an historical perspective informed by the psychological and cosmological understanding of his own time. This book centers on that idea which traditionally has been associated with the very godness of God - the idea of divine abso luteness - and puts certain historical, logical, religious and, finally, cosmological questions to it. The roots of that idea lie in Greek thought, which entered Christian theology via the early church fathers; even so, there is much indication, particularly in Patristic trinitarian thought, that the Biblical heritage is pushing theological thinking towards a social or relative concept of divine being (ch. 1).

Heirlooms and memorabilia are sometimes thought to be valuable for their own sakes even if they lack intrinsic value. They can have extrinsic final value, meaning that they can be valuable for their own sakes on account of their relation to other things. Yet if heirlooms and memorabilia can have this sort of value, then perhaps so can natural entities. If correct, this idea secures the claim that nature is valuable for its own sake without requiring that it have a (...) normative property just in itself. Additionally, it does not commit one to the contentious view that natural entities have a more foundational value than that of persons or sentient beings. Yet it remains to be shown how, precisely, natural entities can have this sort of value. As argued here, one such way is if the given natural entity is related to something else that people are justified in valuing in a partly passive manner. This account then sheds light on the values present in a world increasingly affected by humans. (shrink)

The ability to make informative comparisons is central to human cognition. Comparison involves aligning two representations and placing their elements into correspondence. Detecting correspondences is a necessary component of analogical inference, recognition, categorization, schema formation, and similarity judgment. Connectionist Analogy Builder (CAB) determines correspondences through a simple iterative computation that matches elements in one representation with elements playing compatible roles in the other representation while simultaneously enforcing structural constraints. CAB shows promise as a process model of comparison as its performance (...) can be related to human performance (e.g., solution trajectory, error patterns, time‐on‐task). Furthermore, CAB's bounded working memory allows it to account for the inherent capacity limitations of human processing. CAB's strengths are its parsimony, transparency of operations, and ability to generate performance predictions. In this paper, CAB is evaluated against benchmark phenomena from the analogy literature. (shrink)

A number of writers argue that objects can be valuable for their own sakes on account of their extrinsic features. No one has offered an account, though, that shows exactly how or why objects have this sort of value. I seek to provide such an account. I suggest that an object can have final value on account of its relation to someone one loves or admires, where it is one’s warranted love or admiration for the person that renders the related (...) object valuable for its own sake. I identify a feature of love and admiration that shows exactly why this is the case. I then end by suggesting how this account locates a reason to value non-intrinsically good things for their own sakes that avoids a “wrong reason” objection facing alternative views. (shrink)

We should react to deaf parents who choose to have a deaf child with compassion not condemnationThere has been a great deal of discussion during the past few years of the potential biotechnology offers to us to choose to have only perfect babies, and of the implications that might have, for instance for the disabled. What few people foresaw is that these same technologies could be deliberately used to ensure that children would be born with disabilities. That this is a (...) real possibility, and not merely the thought experiment of a philosopher, is brought home to us by the decision of an American lesbian couple to select a deaf sperm donor in order to maximise the chances that their children, Jehanne and Gauvin, would be deaf like them.1 Their choice has sparked controversy, not only among medical ethicists, but in the opinion pages of newspapers across the world. Ought parents be permitted to make such choices?If the parents of Jehanne and Gauvin have done anything wrong, it must consist in violating their child’s right to an open future—limiting its future potential for choice.2 But what does it mean to respect this right?From the moment a child is born, her parents are making choices for her, which will powerfully shape her future. They will decide what kind of education she will have, what religious experiences, from among what group she can select friends. Thereby, they profoundly mould the person she will be and the life she will have.When this activity is carried out within certain, ill-defined, limits, it is in no way objectionable.

ABSTRACT Many people now believe that human reproductive cloning – once sufficiently safe and effective – should be permitted on the grounds that it will allow the otherwise infertile to have children that are biologically closely related to them. However, though it is widely believed that the possession of a close genetic link to our children is morally significant and valuable, we argue that such a view is erroneous. Moreover, the claim that the genetic link is valuable is pernicious; it (...) tends to give rise to highly undesirable consequences, and therefore should be combated rather than pandered to. The emphasis on the genetic is unwarranted and unfortunate; rather than giving us moral reason to support reproductive cloning in the case of infertility, the fact that cloning requests are likely to be motivated by the genetic argument gives us reason to oppose its availability.

Neutral monist, panpsychist, naturalist, and phenomenological interpretations of James's theory of mind are canvassed. Culling the true tenets from each, I make a case for a reconciling view on the basis of a distinction between mental and proto-mental properties.

To the extent that indeterminacy intervenes between our reasons for action and our decisions, intentions and actions, our freedom seems to be reduced, not enhanced. Free will becomes nothing more than the power to choose irrationally.

In these circumstances, however we choose, we choose rationally. Against this kind of account, most (...) fully developed by Robert Kane, critics have pressed the demand for contrastive explanations. Kane has responded by arguing that the demand does not need to be met: responsibility for an action does not require that there be a contrastive explanation of that action. However, this response proves too much: it implies that agents are responsible not only for the actions they choose, but also for the counterfactual actions which were equally available to them.

Accounts of mechanistic explanation, especially as applied to biology and sometimes going under the heading of “new mechanism,” provided an attractive alternative to nomological accounts that preceded them. These accounts were motivated by selected examples, drawn primarily from cell and molecular biology and neuroscience. However, the range of examples that scientists take to be mechanistic explanations is far broader. We focus on examples that differ from those traditionally recruited by Mechanists. Our contention is that attention to additional examples will lead (...) to a richer conception of mechanistic explanation, prompting a shift from what we refer to as Mechanism 1.0 to Mechanism 2.0.

The principle of epistemic closure is the claim that what is known to follow from knowledge is known to be true. This intuitively plausible idea is endorsed by a vast majority of knowledge theorists. There are significant problems, however, that have to be addressed if epistemic closure – closed knowledge – is endorsed. The present essay locates the problem for closed knowledge in the separation it imposes between knowledge and evidence. Although it might appear that all that stands between knowing (...) the truth of the premises of a valid inference and knowledge of its conclusion is inferring it from the premises, the evidence for each of the premises may jointly count against the conclusion. The intuitive view regarding inferred knowledge says one thing, the evidence says another. One epistemological framework that seems to have the resources to resolve this tension endorses the view that knowledge always requires conclusive evidence. A second framework resolves the tension by limiting the scope of the closure principle. Only inferences drawn directly from propositions contained in the scope of a single knowledge operator are considered closed. The aim of the present essay is to revive the unpopular third option, the idea that knowledge is open. The essay proceeds by arguing that in different ways the two former frameworks only succeed in relocating the problem, not in resolving it. The first framework, the infallibilist view, relocates the problem to a sharp separation between knowledge of the occurrences of events from knowledge of their chance of occurring, a separation leading to several significant additional problems. The fallibilist view, the second framework, in endorsing closure neglects to take into full account the ways in which evidence fails to be transitive. For instance, evidence can count in favor of a conjunction while counting against each of its conjuncts. This fact, which is argued for in the essay on probabilistic as well as non-probabilistic grounds, is used as the foundation of an argument against closed knowledge that can be used as a way to understand several of the most fundamental challenges of epistemology. Not only can an open knowledge view that is based on open evidence resolve all these problems in a simple and natural way, it can also respond to formidable challenges that significantly hinder other open knowledge views. There are good reasons, then, to view both knowledge and evidence as open. (shrink)
