The issue of the biological origin of consciousness is linked to that of its function. One source of evidence in this regard is the contrast between the types of information that are and are not included within its compass. Consciousness presents us with a stable arena for our actions—the world—but excludes awareness of the multiple sensory and sensorimotor transformations through which the image of that world is extracted from the confounding influence of self-produced motion of multiple receptor arrays mounted on (...) multijointed and swivelling body parts. Likewise excluded are the complex orchestrations of thousands of muscle movements routinely involved in the pursuit of our goals. This suggests that consciousness arose as a solution to problems in the logistics of decision making in mobile animals with centralized brains, and has correspondingly ancient roots. (shrink)

A broad range of evidence regarding the functional organization of the vertebrate brain – spanning from comparative neurology to experimental psychology and neurophysiology to clinical data – is reviewed for its bearing on conceptions of the neural organization of consciousness. A novel principle relating target selection, action selection, and motivation to one another, as a means to optimize integration for action in real time, is introduced. With its help, the principal macrosystems of the vertebrate brain can be seen to form (...) a centralized functional design in which an upper brain stem system organized for conscious function performs a penultimate step in action control. This upper brain stem system retained a key role throughout the evolutionary process by which an expanding forebrain – culminating in the cerebral cortex of mammals – came to serve as a medium for the elaboration of conscious contents. This highly conserved upper brainstem system, which extends from the roof of the midbrain to the basal diencephalon, integrates the massively parallel and distributed information capacity of the cerebral hemispheres into the limited-capacity, sequential mode of operation required for coherent behavior. It maintains special connective relations with cortical territories implicated in attentional and conscious functions, but is not rendered nonfunctional in the absence of cortical input. This helps explain the purposive, goal-directed behavior exhibited by mammals after experimental decortication, as well as the evidence that children born without a cortex are conscious. Taken together these circumstances suggest that brainstem mechanisms are integral to the constitution of the conscious state, and that an adequate account of neural mechanisms of conscious function cannot be confined to the thalamocortical complex alone.

Giulio Tononi's integrated information theory (IIT) proposes explaining consciousness by directly identifying it with integrated information. We examine the construct validity of IIT's measure of consciousness,phi(Φ), by analyzing its formal properties, its relation to key aspects of consciousness, and its co-variation with relevant empirical circumstances. Our analysis shows that IIT's identification of consciousness with the causal efficacy with which differentiated networks accomplish global information transfer (which is what Φ in fact measures) is mistaken. This misidentification has the consequence of requiring (...) the attribution of consciousness to a range of natural systems and artifacts that include, but are not limited to, large-scale electrical power grids, gene-regulation networks, some electronic circuit boards, and social networks. Instead of treating this consequence of the theory as a disconfirmation, IIT embraces it. By regarding these systems as bearers of consciousnessex hypothesi, IIT is led toward the orbit of panpsychist ideation. This departure from science as we know it can be avoided by recognizing the functional misattribution at the heart of IIT's identity claim. We show, for example, what function is actually performed, at least in the human case, by the cortical combination of differentiation with integration that IIT identifies with consciousness. Finally, we examine what lessons may be drawn from IIT's failure to provide a credible account of consciousness for progress in the very active field of research concerned with exploring the phenomenon from formal and neural points of view.

Dopamine is critically important in the neural manifestation of motivated behavior, and alterations in the human dopaminergic system have been implicated in the etiology of motivation-related psychiatric disorders, most prominently addiction. Patients with chronic addiction exhibit reduced dopamine D2 receptor (DRD2) availability in the striatum, and the DRD2 TaqIA (rs1800497) and C957T (rs6277) genetic polymorphisms have previously been linked to individual differences in striatal dopamine metabolism and clinical risk for alcohol and nicotine dependence. Here, we investigated the hypothesis that the (...) variants of these polymorphisms would show increased reward-related memory formation, which has previously been shown to jointly engage the mesolimbic dopaminergic system and the hippocampus, as a potential intermediate phenotype for addiction memory. To this end, we performed functional magnetic resonance imaging (fMRI) in 62 young, healthy individuals genotyped for DRD2 TaqIA and C957T variants. Participants performed an incentive delay task, followed by a recognition memory task 24 h later. We observed effects of both genotypes on the overall recognition performance with carriers of low-expressing variants, namely TaqIA A1 carriers and C957T C homozygotes, showing better performance than the other genotype groups. In addition to the better memory performance, C957T C homozygotes also exhibited a response bias for cues predicting monetary reward. At the neural level, the C957T polymorphism was associated with a genotype-related modulation of right hippocampal and striatal fMRI responses predictive of subsequent recognition confidence for reward-predicting items. Our results indicate that genetic variations associated with DRD2 expression affect explicit memory, specifically for rewarded stimuli. We suggest that the relatively better memory for rewarded stimuli in carriers of low-expressing DRD2 variants may reflect an intermediate phenotype of addiction memory. (shrink)

Boyer & Lienard's (B&L's) biological model of ritual achieves a rather straightforward account of features shared by ritual pathology and the idiosyncratic rituals of children; but complexities accrue in extending it to human ritual culture generally. My commentary suggests that the ritual cultural traditions of animals such as songbirds share structural features, handicap-based origin, as well as the enabling neural mechanism of vocal learning with human ritual culture. (Published Online February 8 2007).

Savage et al. propose that music filled a hypothetical “bonding gap” in human sociality by Baldwinian gene-culture coevolution (or protracted cognitive niche construction). Both these stepping stones to an evolutionary account of the function and origin of music are problematic. They are scrutinized in this commentary, and an alternative is proposed.

In our response to a truly diverse set of commentaries, we first summarize the principal topical themes around which they cluster, then address two “outlier” positions. Next, we address ways in which commentaries by non-integrated information theory authors engage with the specifics of our IIT critique, turning finally to the four commentaries by IIT authors.

Conflation of our unique human endowment for language with innate, so-called universal, grammar has banished language from its biological home. The facts reviewed by Evans & Levinson (E&L) fit the biology of cultural transmission. My commentary highlights our dedicated learning capacity for vocal production learning as the form of our language endowment compatible with those facts.

My commentary draws on extensive arguments against “coding in the brain” developed by my neuroscience mentor, the late Eugene Sachs, who summarized them as follows: “[T]he energy in the signal is the only code there is for information…. The code is the same for each cell, but each cell's location is different, and location is the only basis for significance”.

My response addresses general commentary themes such as my neglect of the forebrain contribution to human consciousness, the bearing of blindsight on consciousness theory, the definition of wakefulness, the significance of emotion and pain perception for consciousness theory, and concerns regarding remnant cortex in children with hydranencephaly. Further specific topics, such as phenomenal and phylogenetic aspects of mesodiencephalic-thalamocortical relations, are also discussed. (Published Online May 1 2007).

Pascal Boyer achieves a felicitous integration of what is known about human ownership psychology by deriving ownership intuitions from the interaction of resource acquisition and our cooperative sociality. By exploring the sense of ownership already present in the domain of resource acquisition, I sketch an evolutionary path to the open-ended nature of the specifically human version of that sense.

A number of difficulties encumber the Suddendorf & Corballis (S&C) proposal regarding mental time travel into the future. Among these are conceptual issues turning on the inherent asymmetry of time and causality with regard to past and future, and the bearing of such asymmetry on the uses and utility of retrospective versus prospective mental time travel, on which I comment.

The de minimis principle states that some risks are so trivial that they can be ignored or treated categorically differently from non-trivial risks. Lundgren and Stefánsson criticize the de minimis principle, arguing that it either has to be applied locally or globally and that problems arise whichever application is chosen. Aven and Seif respond to Lundgren and Stefánsson’s argument and defend the de minimis principle as a “meaningful and useful perspective for handling risk in practice.” The response highlights some aspects (...) of the argument in Lundgren and Stefánsson that needs clarification, which is what we do in this note.

According to the class of de minimis decision principles, risks can be ignored (or at least treated very differently from other risks) if the risk is sufficiently small. In this article, we argue that a de minimis threshold has no place in a normative theory of decision making, because the application of the principle will either recommend ignoring risks that should not be ignored (e.g., the sure death of a person) or it cannot be used by ordinary bounded and information-constrained (...) agents.

Recently, Martin Smith defended a view he called the “normic de minimis expected utility theory”. The basic idea is to integrate a ‘normic’ version of the de minimis principle into an expected utility-based decision theoretical framework. According to the de minimis principle some risks are so small (falling below a threshold) that they can be ignored. While this threshold standardly is defined in terms of some probability, the normic conception of de minimis defines this threshold in terms of abnormality. In (...) this article, we present three independent arguments against the normic de minimis expected utility theory, focusing on its reliance on the de minimis principle. (shrink)

Animal ethicists have recently debated the ethical questions raised by disenhancing animals to improve their welfare. Here, we focus on the particular case of breeding hens for commercial egg-laying systems to become blind, in order to benefit their welfare. Many people find breeding blind hens intuitively repellent, yet ‘welfare-only’ positions appear to be committed to endorsing this possibility if it produces welfare gains. We call this the ‘Blind Hens’ Challenge’. In this paper, we argue that there are both empirical and (...) theoretical reasons why even those adopting ‘welfare-only’ views should be concerned about breeding blind hens. But we also argue that alternative views, which (for example) claim that it is important to respect the telos or rights of an animal, do not offer a more convincing solution to questions raised by the possibility of disenhancing animals for their own benefit.

Bjorn T. Ramberg’s book focuses on Davidson’s work in the philosophy of language, published between 1984 and the appearance of the book. Recent papers provide the focus for an overview of Davidson’s philosophy of language and its relations to broader debates and influences. Still, the reader is warned: the author “cannot claim” that the book “is in every detail a faithful representation or development of Davidson’s own current theory.” Instead, what we have is a “reconstruction” of Davidson on language (...) and meaning, an account “Davidsonian in spirit and in all its fundamental features.”1 The result is a projection of Davidson’s views, or important aspects of them, in a particular direction: Davidson and in- terpretation in process. The following critical discussion of main issues in Ramberg’s book should not dis- tract potential readers from this useful and thoughtful overview of Davidson on interpretation and meaning.

Nie war Freundschaft populärer als heute. Sie gilt als entscheidende Zutat für ein gutes und glückliches Leben. Viele haben auch viele Freunde - jedoch will sich das versprochene Glück nicht so recht einstellen. Woran liegt das? Björn Vedder verknüpft in seiner Zeitdiagnose der Freundschaft philosophische Überlegungen mit der Analyse von popkulturellem Material sowie literarischen Klassikern. Er zeigt, was Freundschaft heute bedeutet, wie sie (auch zu uns selbst) gelingen kann und warum Facebook-Freunde echte Freunde sind. Dabei nimmt er die pessimistischen Kulturkritiken (...) der Gegenwart ernst, teilt deren Defätismus aber nicht, sondern zeigt Wege aus den Pathologien der modernen Freundschaft auf. (shrink)

Social entrepreneurship increasingly involves collective, voluntary organizing efforts where success depends on generating and sustaining members’ participation. To investigate how such participatory social ventures achieve member engagement in pluralistic institutional settings, we conducted a qualitative, inductive study of German Renewable Energy Source Cooperatives. Our findings show how value tensions emerge from differences in RESCoop members’ relative prioritization of community, environmental, and commercial logics, and how cooperative leaders manage these tensions and sustain member participation through temporal, structural, and collaborative compromise strategies. (...) We unpack the mechanisms by which each strategy enables members to justify organizational decisions that violate their personal value priorities and demonstrate their varying implications for organizational growth. Our findings contribute new insights into the challenges of collective social entrepreneurship, the capacity of hybrid organizing strategies to mitigate value concessions, and the importance of logic combinability as a key dimension of pluralistic institutional settings.

This article proposes a way to zoom in on the concept of the social license to operate from the broader normative perspective of contractarianism. An SLO can be defined as a contractarian basis for the legitimacy of a company’s specific activity or project. “SLO”, as a fashionable expression, has its origins in business practice. From a normative viewpoint, the concept is closely related to social contract theory, and, as such, it has a political dimension. After outlining the contractarian normative background (...) to the SLO, we will show how academic concepts such as legitimacy and stakeholder management have a tendency to provide the intellectual underpinning for the business case for securing an SLO. While business case perspectives on the SLO may well be in line with the use of the term in business practice, we will highlight certain difficulties and ambiguities related to the instrumental use of the expression. In the final section, we briefly introduce the articles of this Special Issue to the reader and explain how they relate to the topic. (shrink)

This book is the first monograph that takes a comprehensive approach to Jacques Derrida as a philosopher of technology. It refines and complements his mainstream image as a philosopher of language and deconstructionist of classical literary and philosophical texts. This volume outlines the key features of Derrida’s alternative philosophy of technology, a philosophy which Sjöstrand argues, avoids the problems associated with, on the one hand, a Heideggerian orientation, which completely separates thinking and technology and, on the other, an empirically oriented (...) ”post-phenomenology” that can be said to be hegemonic within the field today. Based on a sustained interpretation of Derrida, and a robust, coherent philosophy of technology, a phenomenology of technology is developed that, in a radical way, extends the concept of technology to cover the entire field of phenomenology. This places the technological not in opposition to humanity, but rather always already in close proximity to man and, consequently, to life, ethics, politics, democracy and religion. Strikingly, this important aspect of Derrida’s thinking is only rarely analyzed or discussed by his many exegetes. This text appeals to graduates and researchers working on Derrida, phenomenology, and the philosophy of technology. (shrink)

The focus of this article is the analysis of generative mechanisms, a basic concept and phenomenon within the metatheoretical perspective of critical realism. It is emphasized that research questions and methods, as well as the knowledge it is possible to attain, depend on the basic view – ontologically and epistemologically – regarding the phenomenon under scrutiny. A generative mechanism is described as a trans empirical but real existing entity, explaining why observable events occur. Mechanisms are mostly possible to grasp only (...) indirectly by analytical work, based however on empirical observations. In order to achieve such an explanatory analysis, five methodological steps are suggested and discussed, among them abduction and retroduction. These steps are illustrated throughout by examples drawn from empirical research regarding social work practice. The article is concluded with a discussion of the need for knowledge of generative mechanisms. (shrink)

The ‘Guiding Principles on Business and Human Rights’ (Principles) that provide guidance for the implementation of the United Nations’ ‘Protect, Respect and Remedy’ framework (Framework) will probably succeed in making human rights matters more customary in corporate management procedures. They are likely to contribute to higher levels of accountability and awareness within corporations in respect of the negative impact of business activities on human rights. However, we identify tensions between the idea that the respect of human rights is a perfect (...) moral duty for corporations and the Principle’s ‘human rights due diligence’ requirement. We argue that the effectiveness of the ‘human rights due diligence’ is in many respects dependent upon the moral commitment of corporations. The Principles leave room for an instrumental or strategic implementation of due diligence, which in some cases could result in a depreciation of the fundamental norms they seek to promote. We reveal some limits of pragmatic approaches to coping with business-related human rights abuses. As these limits become more apparent, not only does the case for further progress in international and extraterritorial human rights law become more compelling, but so too does the argument for a more forceful discussion on the moral foundations of human rights duties for corporations.

Psychoanalytic work with children is popular, but the sophisticated language used in psychoanalytic discourse can be at odds with how children communicate, and how best to communicate with them. _Dialogues with Children and Adolescents: A Psychoanalytic Guide _shows how these aims can be achieved for the most effective clinical outcome with children from infancy up to late adolescence. _Björn Salomonsson_ and _Majlis Winberg Salomonsson_ draw on extensive case material which reveals the essence of communication between child and therapist. They enfranchise (...) the patient of all ages as an equal participant in the therapeutic relationship. Presented in letter form the cases contain no professional terms. Only the final chapter contains theoretical commentaries applicable to each case. These terms and theories help to explain a child’s behaviour, the analyst’s technique and the background to the disorder. This is new creative development in child therapy and analysis which is written in a very accessible style. _Dialogues with Children and Adolescents_ will be essential reading for beginners in psychoanalytic work with children and will cast a fresh light on such work for more experienced clinicians. It will also appeal to the non-professional lay reader. (shrink)

This study investigates the interrelation of outer appearance and spatial configuration of modern Chinese court buildings with the party-state’s strategy of building regime legitimacy. The spatial element of this relation is explored in four different court buildings in Kunming, Chongqing, Shanghai and Xi’an. It is argued that court buildings contribute to the empowerment of individuals who appear as parties in trials. Courthouses also facilitate the courts’ function of exercising social control and the application of an instrumentalist approach to the principle (...) of public trials. Both the grounding of court buildings in the past and their compliance with international models of a modern independent judiciary are aspects of consolidating regime legitimacy. (shrink)

In this paper, we try to shed light on the ontological puzzle pertaining to models and to contribute to a better understanding of what models are. Our suggestion is that models should be regarded as a specific kind of signs according to the sign theory put forward by Charles S. Peirce, and, more precisely, as icons, i.e. as signs which are characterized by a similarity relation between sign (model) and object (original). We argue for this (1) by analyzing from a (...) semiotic point of view the representational relation which is characteristic of models. We then corroborate our hypothesis (2) by discussing the conceptual differences between icons, i.e. models, and indexical and symbolic signs and (3) by putting forward a general classification of all icons into three functional subclasses (images, diagrams, and metaphors). Subsequently, we (4) integratively refine our results by resorting to two influential and, as can be shown, complementary philosophy of science approaches to models. This yields the following result: models are determined by a semiotic structure in which a subject intentionally uses an object, i.e. the model, as a sign for another object, i.e. the original, in the context of a chosen theory or language in order to attain a specific end by instituting a representational relation in which the syntactic structure of the model, i.e. its attributes and relations, represents by way of a mapping the properties of the original, which hence are regarded as similar in a relevant manner.

Ethnic slur terms and other group-based slurs must be differentiated from general pejoratives and pure expressives. As these terms pejoratively refer to certain groups of people, they are a typical feature of hate speech contexts where they serve xenophobic speakers in expressing their hatred for an entire group of people. However, slur terms are actually far more frequently used in other contexts and are more often exchanged among friends than between enemies. Hate speech can be identified as the most central, (...) albeit not the most frequent, mode of use. I broadly distinguish between hate speech, other pejorative uses, parasitic uses, neutral mentioning, and unaware uses. In this paper, authentic examples of use and frequency estimates from empirical research will help provide accurate definitions and insight into these different modes that purely theoretical approaches cannot achieve.
