The genome sequencing revolution has revealed that all species possess a large number of unique genes critical for trait variation, adaptation, and evolutionary innovation. One widely used approach to identify such genes consists of detecting protein‐coding sequences with no homology in other genomes, termed orphan genes. These genes have been extensively studied, under the assumption that they represent valid proxies for species‐specific genes. Here, we critically evaluate taxonomic, phylogenetic, and sequence evolution evidence showing that orphan genes belong to a range (...) of evolutionary ages and thus cannot be assigned to a single lineage. Furthermore, we show that the processes generating orphan genes are substantially more diverse than generally thought and include horizontal gene transfer, transposable element domestication, and overprinting. Thus, orphan genes represent a heterogeneous collection of genes rather than a single biological entity, making them unsuitable as a subject for meaningful investigation of gene evolution and phenotypic innovation.

You know what someone else is thinking and feeling by observing them. But how do you know what you are thinking and feeling? This is the problem of self-knowledge: Alex Byrne tries to solve it. The idea is that you know this not by taking a special kind of look at your own mind, but by an inference from a premise about your environment.

Robotic warfare has now become a real prospect. One issue that has generated heated debate concerns the development of ‘Killer Robots’. These are weapons that, once programmed, are capable of finding and engaging a target without supervision by a human operator. From a conceptual perspective, the debate on Killer Robots has been rather confused, not least because it is unclear how central elements of these weapons can be defined. Offering a precise take on the relevant conceptual issues, the article contends (...) that Killer Robots are best seen as executors of targeting decisions made by their human programmers. However, from a normative perspective, the execution of targeting decisions by Killer Robots should worry us. The article argues that what is morally bad about Killer Robots is that they replace human agency in warfare with artificial agency, a development which should be resisted. Finally, the article contends that the issue of agency points to a wider problem in just war theory, namely the role of moral rights in our normative reasoning on armed conflict. (shrink)

Cultural evolution studies are characterized by the notion that culture evolves accordingly to broadly Darwinian principles. Yet how far the analogy between cultural and genetic evolution should be pushed is open to debate. Here, we examine a recent disagreement that concerns the extent to which cultural transmission should be considered a preservative mechanism allowing selection among different variants, or a transformative process in which individuals recreate variants each time they are transmitted. The latter is associated with the notion of “cultural (...) attraction”. This issue has generated much misunderstanding and confusion. We first clarify the respective positions, noting that there is in fact no substantive incompatibility between cultural attraction and standard cultural evolution approaches, beyond a difference in focus. Whether cultural transmission should be considered a preservative or reconstructive process is ultimately an empirical question, and we examine how both preservative and reconstructive cultural transmission has been studied in recent experimental research in cultural evolution. Finally, we discuss how the relative importance of preservative and reconstructive processes may depend on the granularity of analysis and the domain being studied. (shrink)

Contemporary process metaphysics has achieved a number of important results, most significantly in accounting for emergence, a problem on which substance metaphysics has foundered since Plato. It also faces trenchant problems of its own, among them the related problems of boundaries and individuation. Historically, the quest for ontology may thus have been largely responsible for the persistence of substance metaphysics. But as Plato was well aware, an ontology of substantial things raises serious, perhaps insurmountable problems for any account of our (...) epistemic access to such things. Physical things are subject to change, and as such, they are poor objects of knowledge—if knowledge is to be more reliable than mere opinion. There is a reading of Plato’s Theaetetus on which knowledge may be understood as a relation between an epistemic subject and a logos, where logoi are intrinsically dialectical, and where dialectic is a kind of intersubjective activity. Insofar as this epistemology may be attributed to Plato, the project of this paper is Platonic in spirit. It is also, in a sense, Kantian, in that it divorces ontology from the search for things-in-themselves, redirecting our attention from things to objects: epistemic objects. Such objects can be understood, as Maurice Merleau-Ponty proposed, as shared by multiple subjects by virtue of their participation in an intersubjective world, constituted by what Shaun Gallagher calls participatory sense-making. On an epistemology constructed in this way, the fact that both epistemic objects and their subject are mutable is no obstacle to knowledge. Far-from-equilibrium systems are forever mutable; at thermodynamic equilibrium, there would be neither subject, nor object. Epistemic objects, on this picture, are metastable loci of interactive potential. (shrink)

There is extensive evidence that adults, children, and some non-human species, represent routine events in the form of hierarchically structured 'action scripts,' and show superior recall and imitation of information at relatively high-levels of this hierarchy. Here we investigate the hypothesis that a 'hierarchical bias' operates in human cultural transmission, acting to impose a hierarchical structure onto descriptions of everyday events, and to increasingly describe those events in terms of higher hierarchical levels. Descriptions of three everyday events expressed entirely in (...) terms of basic low-level actions were transmitted along ten chains each containing four adult human participants. It was found that the proportion of low-level information showed a significant linear decrease with transmission generation, while the proportions of medium- and high-level information showed significant linear increases, consistent with the operation of a hierarchical bias. The findings additionally provide support for script theory in general, and are discussed in relation to hierarchical imitation in non-human primates. (shrink)

It is commonly supposed that at least some states possess a moral right against external intervention in their domestic affairs and all human rights violations give members of the international community reasons to undertake preventive or remedial action against offending states. No state, however, currently protects or could reasonably be expected to protect its subjects’ human rights to a perfect degree. In view of this reality, many have found it difficult to explain how any existing or readily foreseeable state could (...) enjoy a moral right of nonintervention without denying the normative force of human rights. This article seeks to reconcile these apparently incompatible commitments by arguing that, in addition to acting in defense of human rights, outsiders must be appropriately responsive to individuals’ distinct and potentially countervailing interests in collective self-determination. I show that, under certain demanding but not unrealistic conditions, individuals’ interests in self-determination are of sufficient weight not simply to ground a judgment against intervention in particular cases but to generate arobust right of nonintervention on the part of some states that nevertheless fail to secure perfect protection of their subjects’ human rights.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume XXIV, Number 2, November 1998, pp. 335-354 "An Unaccountable Pleasure": Hume on Tragedy and the Passions ALEX NEILL Hume begins his essay "Of Tragedy" with a description of what he calls "a singular phaenomenon": It seems an unaccountable pleasure, which the spectators of a well-written tragedy receive from sorrow, terror, anxiety, and other passions, that are in themselves disagreeable and uneasy. The more they are (...) touched and affected, the more are they delighted with the spectacle; and as soon as the uneasy passions cease to operate, the piece is at an end.... They are pleased in proportion as they are afflicted, and never are so happy as when they employ tears, sobs, and cries to give vent to their sorrow, and relieve their heart, swoln with the tenderest sympathy and compassion. The few critics who have had some tincture of philosophy, have remarked this singular phaenomenon, and have endeavoured to account for it.1 The account of the audience's experience of tragedy that Hume goes on to offer in "Of Tragedy" has been the target of criticism since the essay was published. My purpose in what follows is to show that some of what may appear to be the most damaging of that criticism is based on a misinterpretation of the thesis that Hume develops in the essay. I shall not attempt to argue that Hume's thesis is persuasive; indeed, I believe and have argued Alex Neill is at the Department of Philosophy, University of Southampton, Hants Sl 7 IBJ ENGLAND. 336 Alex Neill elsewhere that it is not.2 My project here is almost entirely interpretive: it is an attempt to get clear about what Hume's thesis concerning our experience of tragedy really is. To that end, it should be noted that the apparently "unaccountable" pleasure Hume describes at the beginning of "Of Tragedy" is something that he has remarked on before. In Book I of the Treatise, he notes that in matters of religion men take a pleasure in being terrify'd, and that no preachers are so popular, as those who excite the most dismal and gloomy passions. In the common affairs of life, where we feel and are penetrated with the solidity of the subject, nothing can be more disagreeable than fear and terror; and 'tis only in dramatic performances and in religious discourses, that they ever give pleasure? The phenomenon that Hume finds so remarkable in these passages from "Of Tragedy" and the Treatise is thus, at a minimum, that in certain circumstances, such as when we are at the theatre, we may find agreeable the experience of "the most dismal and gloomy passions." The explanation he gives of this phenomenon in the Treatise is as follows: In these latter cases the imagination reposes itself indolently on the idea; and the passion, being soften'd by the want of belief in the subject, has no more than the agreeable effect of enlivening the mind, and fixing the attention. (T 115) Hume's explanation of how the experience of "uneasy" passions can be enjoyed when we are in church and at the theatre thus has two components. First, because we do not believe the stories we are told in church4 and at the theatre, the uneasy passions we experience are not so very uneasy; as he puts it later in the Treatise, in such circumstances the passion in question "lies not with that weight upon us: It feels less firm and solid" (T 631). Second, a weakly disagreeable passion of this sort agreeably "enlivens" the mind and "fixes" (or as he says later, "rouzes") our attention. By the time he wrote "Of Tragedy," however, Hume had come to regard this explanation of his "singular phaenomenon" as inadequate. With regard to the idea that the passions, even if "uneasy," have the pleasurable effect of "enlivening" the mind (an idea which in "Of Tragedy" he attributes to Dubos), Hume objects that having one's mind "enlivened," one's attention "fixed" or "rouzed," need not be pleasurable: "the same object of distress, which pleases in a tragedy, were it really set before us, would give the most unfeigned uneasiness; though it...

Many scholars have rejected cultural evolutionary theory on the grounds that cultural variation is directed and intentionally created, rather than incremental and blind with respect to function, as is the case for novel genetic variation in genetic evolution. Meanwhile, some cultural evolution researchers insist that cultural variation is blind and undirected, and the only directional force is selection of randomly-generated variants. Here I argue that neither of these positions are tenable. Cultural variation is directed in various ways. While this does (...) not invalidate cultural evolution, more attention should be paid to the different sources of non-randomness in culturally evolving systems. (shrink)

Among other interesting claims made in Robert Reich's 2007 treatise, Supercapitalism, it is asserted in various ways that proponents of corporate social responsibility (CSR) or what I would call 'business ethics' are engaged in relatively unproductive exercises. Their resources would be better used if they undertook the hard work of engagement in democratic political processes leading to legislation that would force corporations to pursue the public interest as well as their own. In this article, I summarize some of Reich's central (...) theses and arguments, show that they are fatally flawed and explain why the institution of morality is essential for business, law and democracy.

Nineteenth and twentieth century philosophies of science have consistently failed to identify any rational basis for the compelling character of scientific analogies. This failure is particularly worrisome in light of the fact that the development and diffusion of certain scientific analogies, e.g. Darwin’s analogy between domestic breeds and naturally occurring species, constitute paradigm cases of good science. It is argued that the interactivist model, through the notion of a partition epistemology, provides a way to understand the persuasive character of compelling (...) scientific analogies without consigning them to an irrational or arational context of discovery.

This paper expands the definition of gray-marketing to include some ethically problematic marketing activities and techniques used in personal selling in China. Based on this, a conceptual model of gray-marketing for a particular type of selling in which both the sellers and the buyers exhibit problematic ethics in an exchange and the associated hypotheses are developed and tested. The findings show that, first, the respondents have different ethical evaluations of different marketing practices used in personal selling such as giving and (...) accepting gifts, buying and accepting meals, and offering and accepting kickbacks. Some of these practices may not be considered unethical. Second, in terms of ethical assessment, gray-marketing practiced by buying agents is more unacceptable than when practiced by sales agents. Third, a person's ethical evaluation of gray-marketing behavior, empathy for gray-marketing, and belief that gray-marketing has serious consequences, significantly affects his inclination to use gray-marketing. This paper concludes with a discussion of some possible applications of our research findings. (shrink)

We are encouraged that the majority of commentators endorse our evolutionary framework for studying culture, and several suggest extensions. Here we clarify our position, dwelling on misunderstandings and requests for exposition. We reiterate that using evolutionary biology as a model for unifying the social sciences within a single synthetic framework can stimulate a more progressive and rigorous science of culture.

The study has two objectives: to introduce grip force recording as a new technique for studying embodied numerical processing; and to demonstrate how three competing accounts of numerical magnitude representation can be tested by using this new technique: the Mental Number Line, A Theory of Magnitude and Embodied Cognition account. While 26 healthy adults processed visually presented single digits in a go/no-go n-back paradigm, their passive holding forces for two small sensors were recorded in both hands. Spontaneous and unconscious grip (...) force changes related to number magnitude occurred in the left hand already 100–140 ms after stimulus presentation and continued systematically. Our results support a two-step model of number processing where an initial stage is related to the automatic activation of all stimulus properties whereas a later stage consists of deeper conscious processing of the stimulus. This interpretation generalizes previous work with linguistic stimuli and elaborates the timeline of embodied cognition. We hope that the use of grip force recording will advance the field of numerical cognition research. (shrink)

There are presently two leading foreign policy decision-making paradigms in vogue. The first is based on the classical or rational model originally posited by von Neumann and Morgenstern to explain microeconomic decisions. The second is based on the cybernetic perspective whose groundwork was laid by Herbert Simon in his early research on bounded rationality. In this paper we introduce a third perspective — thepoliheuristic theory of decision-making — as an alternative to the rational actor and cybernetic paradigms in international relations. (...) This theory is drawn in large part from research on heuristics done in experimental cognitive psychology. According to the poliheuristic theory, policy makers use poly (many) heuristics while focusing on a very narrow range of options and dimensions when making decisions. Among them, the political dimension is noncompensatory. The paper also delineates the mathematical formulations of the three decision-making models. (shrink)

A profile of teacher competences is described and interrogated in the light of inherent, language-based problematics. It is argued that such texts tend to constrain the modes and parameters within which to think about one's practice, in addition to masking possible deficiences in education systems through a pathologisation of the individual practitioner. The importance of keeping alive alternative discourses is stressed. Such discourses, it is argued, should recognise the complex idiosyncratic, contingent aspects of teaching and learning, and should include students' (...) reflections on their own in- and out-school experiences through dialogic, autobiographical writing.

Cultural evolutionary theories define prestige as social rank that is freely conferred on individuals possessing superior knowledge or skill, in order to gain opportunities to learn from such individuals. Consequently, information provided by prestigious individuals should be more memorable, and hence more likely to be culturally transmitted, than information from non-prestigious sources, particularly for novel, controversial arguments about which preexisting opinions are absent or weak. It has also been argued that this effect extends beyond the prestigious individual’s relevant domain of (...) expertise. We tested whether the prestige and relevance of the sources of novel, controversial arguments affected the transmission of those arguments, independently of their content. In a four-generation linear transmission chain experiment, British participants recruited online read two conflicting arguments in favour of or against the replacement of textbooks by computer tablets in schools. Each of the two conflicting arguments was associated with one of three sources with different levels of prestige and relevance. Participants recalled the pro-tablets and anti-tablets arguments associated with each source and their recall was then passed to the next participant within their chain. Contrary to our predictions, we did not find a reliable effect of either the prestige or relevance of the sources of information on transmission fidelity. We discuss whether the lack of a reliable effect of prestige on recall might be a consequence of differences between how prestige operates in this experiment and in everyday life. (shrink)

In this period of transition of state monopoly capitalism the working class has become the large majority. Within this majority the proletariat, due to the exchange character of its power, constitutes the care. Beside it new groups of intellectuals are emerging with radical-democratic demands.

This book brings together two of the most powerful and relevant philosophical critiques of human rights: the post-colonialist and the post-Althusserian, its balanced internal structure not just throwing these two critiques together, but actually forcing them to enter into confrontation and dialogue. The book is organised in three parts: at each end, the post-colonialist and the post-Althusserian critiques are represented by some of their main thinkers, while in the middle, an American intermezzo functions as a genuine Derridian supplement: always already (...) contaminating the purity of the two theoretical schools, preventing their enclosure and, hence, fuelling and complicating further their mutual confrontation. As in any authentic dialogue, the introduction and the conclusion each claim victory for one of the sides by changing the very terms and rules of the dialogue, picturing it as a confrontation between emancipatory universalism and inefficient particularism, or as a split between hypocrisy and truth.

Perception of (and during) events is a necessary feature of any perceptual theory. Norman's dual-process approach cannot account for the perception of events without substantial interactions between the dorsal and ventral systems. These interactions, as outlined by Norman, are highly problematical. The necessity for interactions between the two systems makes the distinction useless.

Penelope Maddy's original solution to the dilemma posed by Benacerraf in his 'Mathematical Truth' was to reconcile mathematical empiricism with mathematical realism by arguing that we can perceive realistically construed sets. Though her hypothesis has attracted considerable critical attention, much of it, in my view, misses the point. In this paper I vigorously defend Maddy's account against published criticisms, not because I think it is true, but because these criticisms have functioned to obscure a more fundamental issue that is well (...) worth addressing: in general -- and not only in the mathematical domain -- empiricism and realism simply cannot be reconciled by means of an account of perception anything like Maddy's. But because Maddy's account of perception is so plausible, this conclusion raises the specter of the broader incompatibility of realism and empiricism, which contemporary philosophers are frequently at pains to forget.

This article discusses Kracauer’s analysis of mass ornament in light of Deleuze’s concept of ritournelle. Kracauer was interested in the spectacle of Tiller Girls and found the principle of the capitalist production process in its ornamental formations. Capitalism destroys any natural organisms for its means and excludes any resistance from its effective procedure. This operation necessarily comes along with calculation and mechanisation. All individuals have scaled up statistics charts and scrambled with machines completely. People have turned into masses who are (...) no longer different in form but simple technical objects that can be equally employed at any point of the globe. Kracauer understood mass ornament as the surface-level expression of global capitalism, which revealed its unconscious. He emphasised the ambivalence of mass ornament and a possible line of escape from capitalist rationality through the emptiness of its formal excess. Deleuze’s concept of ritournelle may shed light on a similar question of mass ornament and push its scope beyond Kracauer’s analysis. The two philosophers seem to share the frame of formalism when they deploy their arguments concerning form and depth; however, Deleuze put forward the issue of temporality in his discussion of ritournelle, a crucial question that Kracauer omits.

Resumen: Durante la década del sesenta, la revista Movie hereda de Cahiers du cinéma las preferencias por la politique des auteurs y por cierto cine norteamericano. No obstante, sin abandonar esa predilección por un “cine de directores”, a lo largo de su trayectoria la revista británica intentará desarrollar un riguroso método de análisis formal a través de detallados close readings de los films. Algunos de sus integrantes buscan aplicar al cine los planteos de F. R. Leavis y la revista Scrutiny (...) a propósito de la crítica literaria. Es esta modulación analítica la que será puesta en cuestión con el auge del estructuralismo y el posestructurailsmo a los que se asocia la revista Screen en los años 70.: During the sixties, the journal Movie inherits from Cahiers du cinéma the preferencies for a politique des auteurs and for certain american films. However, never abandoning this tendency towards a “cinema of directors”, the british journal develops a rigorous method of formal analysis and detailed close readings. Some of its members try to apply to cinema the concepts elaborated by F. R. Leavis and the journal Scrutiny in reference to literary criticism. It is precisely this analytic method that will be questioned during the boom of structuralism and post structuralism to which the journal Screen will be asociated in the 70s. (shrink)

Drawing on a small sample of writings from distinguished philosophers and poets living in the Middle East in the period from the eighth to the first century BCE, it is shown that a variety of business practices provided familiar examples of how people ought to act and live, morally speaking, to enjoy the best sort of life and to be the best sort of person. The writings reveal that we share a common heritage and humanity with people living 20 to (...) 28 hundred years ago, and that some of the observations are as important and useful today as they were when they were originally made.
