Astrobiologists are aware that extraterrestrial life might differ from known life, and considerable thought has been given to possible signatures associated with weird forms of life on other planets. So far, however, very little attention has been paid to the possibility that our own planet might also host communities of weird life. If life arises readily in Earth-like conditions, as many astrobiologists contend, then it may well have formed many times on Earth itself, which raises the question whether one or (...) more shadow biospheres have existed in the past or still exist today. In this paper, we discuss possible signatures of weird life and outline some simple strategies for seeking evidence of a shadow biosphere.

This book tackles the most difficult and profound open questions about life and its origins from an information-based perspective.

The problem of life’s origin remains one of the great outstanding challenges to science. Ever since Charles Darwin mused about a “warm little pond” incubating life beneath sunny primeval skies, scientists have speculated about the exact location of this transforming event. Nearly a century and a half later, we remain almost completely ignorant of the physical processes that led from a nonliving chemical mixture to the first autonomous organism. However, some progress at least has been made on tracking down where (...) and when life first established itself on Earth. Fossil evidence suggests that the biological record extends back at least 3.5 billion years, pointing to a still earlier origin1. But this presents a problem. The cratering record of the moon implies that Earth was subjected to intense bombardment by large comets and asteroids over an extended duration until about 3.8 billion years ago. The largest of these impacts would have released enough energy to swathe the planet in incandescent rock vapour, boiling the oceans and sending sterilizing heat pulses a kilometre into the exposed crust2. This unpromising setting – hardly a secure one for warm little ponds – has prompted some astrobiologists to conjecture that life began somewhere else and came to Earth readymade3. Favourite among extraterrestrial originating locations is the planet Mars4. (shrink)

The importance of applying game theory to the evolution of information in the presence of noise has recently become widely recognized. This Special Issue addresses the theme of spontaneously emergent order in both classical and quantum systems subject to external noise, and includes papers directly related to game theory or the development of supporting techniques. In the following editorial overview we examine the broader context of the subject, including the tension between the destructive and creative aspects of noise, and foreshadow (...) the significance of some of the subsequent papers in the volume.

There is a widespread assumption that the universe in general, and life in particular, is 'getting more complex with time'. This book brings together a wide range of experts in science, philosophy and theology and unveils their joint effort in exploring this idea. They confront essential problems behind the theory of complexity and the role of life within it: what is complexity? When does it increase, and why? Is the universe evolving towards states of ever greater complexity and diversity? If (...) so, what is the source of this universal enrichment? This book addresses those difficult questions, and offers a unique cross-disciplinary perspective on some of the most profound issues at the heart of science and philosophy. Readers will gain insights in complexity that reach deep into key areas of physics, biology, complexity science, philosophy and religion. (shrink)

In the atavistic model of cancer progression, tumor cell dedifferentiation is interpreted as a reversion to phylogenetically earlier capabilities. The more recently evolved capabilities are compromised first during cancer progression. This suggests a therapeutic strategy for targeting cancer: design challenges to cancer that can only be met by the recently evolved capabilities no longer functional in cancer cells. We describe several examples of this target‐the‐weakness strategy. Our most detailed example involves the immune system. The absence of adaptive immunity in immunosuppressed (...) tumor environments is an irreversible weakness of cancer that can be exploited by creating a challenge that only the presence of adaptive immunity can meet. This leaves tumor cells more vulnerable than healthy tissue to pathogenic attack. Such a target‐the‐weakness therapeutic strategy has broad applications, and contrasts with current therapies that target the main strength of cancer: cell proliferation. (shrink)

: All known life requires phosphorus (P) in the form of inorganic phosphate (PO43x or Pi) and phosphate-containing organic molecules. Pi serves as the backbone of the nucleic acids that constitute genetic material and as the major repository of chemical energy for metabolism in polyphosphate bonds. Arsenic (As) lies directly below P on the periodic table and so the two elements share many chemical properties, although their chemistries are sufficiently dissimilar that As cannot directly replace P in modern biochemistry. Arsenic (...) is toxic because As and P are similar enough that organisms attempt this substitution. We hypothesize that ancient biochemical systems, analogous to but distinct from those known today, could have utilized arsenate in the equivalent biological role as phosphate. Organisms utilizing such ‘ weird life ’ biochemical pathways may have supported a ‘ shadow biosphere ’ at the time of the origin and early evolution of life on Earth or on other planets. Such organisms may even persist on Earth today, undetected, in unusual niches. (shrink)

Corporate social responsibility is a tortured concept. We review the current state of the art across a number of academic disciplines, from accounting to management to theology. In a world that is increasingly global and pluralistic, progress in our understanding of CSR must include theorizing around the micro-level processes practicing managers engage in when allocating resources toward social initiatives, as well as refined measurement of the outcomes of those initiatives on stakeholder and shareholder interests. Scholarship must also account for the (...) influence of diverse, and even maladaptive, stakeholders as well as more fully incorporate non-Western philosophical and economic perspectives. Based on this review, we pose five questions that scholars from each of these disciplines should address as the CSR field moves forward. We hope our questions provoke deeper thinking and greater rigor and attention to detail in this important area of business research. (shrink)

It has long been recognized that cancer onset and progression represent a type of reversion to an ancestral quasi‐unicellular phenotype. This general concept has been refined into the atavistic model of cancer that attempts to provide a quantitative analysis and testable predictions based on genomic data. Over the past decade, support for the multicellular‐to‐unicellular reversion predicted by the atavism model has come from phylostratigraphy. Here, we propose that cancer onset and progression involve more than a one‐off multicellular‐to‐unicellular reversion, and are (...) better described as a series of reversionary transitions. We make new predictions based on the chronology of the unicellular‐eukaryote‐to‐multicellular‐eukaryote transition. We also make new predictions based on three other evolutionary transitions that occurred in our lineage: eukaryogenesis, oxidative phosphorylation and the transition to adaptive immunity. We propose several modifications to current phylostratigraphy to improve age resolution to test these predictions. Also see the video abstract here: https://youtu.be/3unEu5JYJrQ. (shrink)

Over 90% of the organs transplanted in China before 2010 were procured from prisoners. Although Chinese officials announced in December 2014 that the country would completely cease using organs harvested from prisoners, no regulatory adjustments or changes in China’s organ donation laws followed. As a result, the use of prisoner organs remains legal in China if consent is obtained. We have collected and analysed available evidence on human rights violations in the organ procurement practice in China. We demonstrate that the (...) practice not only violates international ethics standards, it is also associated with a large scale neglect of fundamental human rights. This includes organ procurement without consent from prisoners or their families as well as procurement of organs from incompletely executed, still-living prisoners. The human rights critique of these practices will also address the specific situatedness of prisoners, often conditioned and traumatized by a cascade of human rights abuses in judicial structures. To end the unethical practice and the abuse associated with it, we suggest to inextricably bind the use of human organs procured in the Chinese transplant system to enacting Chinese legislation prohibiting the use of organs from executed prisoners and making explicit rules for law enforcement. Other than that, the international community must cease to abet the continuation of the present system by demanding an authoritative ban on the use of organs from executed Chinese prisoners.

We present an exactly soluble electron trajectory that permits an analysis of the soft (deep infrared) radiation emitted, the existence of which has been experimentally observed during beta decay via lowest order inner bremsstrahlung. Our treatment also predicts the time evolution and temperature of the emission, and possibly the spectrum, by analogy with the closely related phenomenon of the dynamic Casimir effect.

Organ donation after brain death has been practiced in China since 2003 in the absence of brain death legislation. Similar to international standards, China’s brain death diagnostic criteria include coma, absence of brainstem reflexes, and the lack of spontaneous respiration. The Chinese criteria require that the lack of spontaneous respiration must be verified with an apnea test by disconnecting the ventilator for 8 min to provoke spontaneous respiration. However, we have found publications in Chinese medical journals, in which the donors (...) were declared to be brain dead, yet without an apnea test. The organ procurement procedures started with initiating “intratracheal intubation for mechanical ventilation after brain death,” indicating that a brain death diagnosis was not performed. The purpose of the intubation was not to resuscitate the patient but rather was directly related to facilitating the explantation of organs. Moreover, it was unmistakably stated in two of these publications that the cardiac arrest was induced in these patients without brain death determination by cold St. Thomas cardioplegic solution or other cold myocardial protection solutions. This means that the condition of these donors neither met the criteria of brain death nor that of cardiac death. In other words, the “donor organs” may well have been procured in these cases from living human beings. Thus, brain death definition is abused in China by some individuals for organ harvesting, and a systematic investigation is needed to clarify the situation of organ donation after brain death in China.

Paul C. Taylor provides an accessible guide to a well-travelled but still-mysterious area of the contemporary social landscape. The result is the first philosophical introduction to the field of race theory and to a non-biological and situational notion of race. Provides the first philosophical introduction to the field of race theory. Outlines the main features and implications of race-thinking; asks questions such as: What is race-thinking? Don’t we know better than to talk about race now? Are there any races? (...) What is it like to have a racial identity? Engages with the ideas of such important figures as Linda Alcoff, K. Anthony Appiah, W.E.B. Du Bois, Howard Winant, and Naomi Zack. Explores the enduring significance of race in relation to culture, personal relationships and social justice. (shrink)

Sense of agency refers to the sense of initiating and controlling actions in order to influence events in the outside world. Recently, a distinction between implicit and explicit aspects of sense of agency has been proposed, analogous to distinctions found in other areas of cognition, notably learning. However, there is yet no strong evidence supporting separable implicit and explicit components of sense of agency. The so-called ‘Perruchet paradigm’ offers one of the few convincing demonstrations of separable implicit and explicit learning (...) systems. We adopted this approach to evaluate the implicit–explicit distinction in the context of a simple task in which outcomes were probabilistically caused by actions. In line with our initial predictions, we found evidence of a dissociation. We discuss the implications of this result for theories of sense of agency. (shrink)

Hand function improvement in stroke survivors in the chronic stage usually plateaus by 6 months. Brain-computer interface (BCI)-guided robot-assisted training has been shown to be effective for facilitating upper-limb motor function recovery in chronic stroke. However, the underlying neuroplasticity change is not well understood. This study aimed to investigate the whole-brain neuroplasticity changes after 20-session BCI-guided robot hand training, and whether the changes could be maintained at the 6-month follow-up. Therefore, the clinical improvement and the neurological changes before, immediately after, (...) and 6 months after training were explored in 14 chronic stroke subjects. The upper-limb motor function was assessed by Action Research Arm Test (ARAT) and Fugl-Meyer Assessment for Upper-Limb (FMA), and the neurological changes were assessed using resting-state functional magnetic resonance imaging. Repeated-measure ANOVAs indicated that long-term motor improvement was found by both FMA (F[2,26]= 6.367,p= 0.006) and ARAT (F[2,26]= 7.230,p= 0.003). Seed-based functional connectivity analysis exhibited that significantly modulated FC was observed between ipsilesional motor regions (primary motor cortex and supplementary motor area) and contralesional areas (supplementary motor area, premotor cortex, and superior parietal lobule), and the effects were sustained after 6 months. The fALFF analysis showed that local neuronal activities significantly increased in central, frontal and parietal regions, and the effects were also sustained after 6 months. Consistent results in FC and fALFF analyses demonstrated the increase of neural activities in sensorimotor and fronto-parietal regions, which were highly involved in the BCI-guided training.Clinical Trial Registration:This study has been registered atClinicalTrials.govwith clinical trial registration number NCT02323061.

BackgroundIn December 2014, China announced that only voluntarily donated organs from citizens would be used for transplantation after January 1, 2015. Many medical professionals worldwide believe that China has stopped using organs from death-row prisoners.DiscussionIn the present article, we briefly review the historical development of organ procurement from death-row prisoners in China and comprehensively analyze the social-political background and the legal basis of the announcement. The announcement was not accompanied by any change in organ sourcing legislations or regulations. As a (...) fact, the use of prisoner organs remains legal in China. Even after January 2015, key Chinese transplant officials have repeatedly stated that death-row prisoners have the same right as regular citizens to “voluntarily donate” organs. This perpetuates an unethical organ procurement system in ongoing violation of international standards.ConclusionsOrgan sourcing from death-row prisoners has not stopped in China. The 2014 announcement refers to the intention to stop the use of organs illegally harvested without the consent of the prisoners. Prisoner organs procured with “consent” are now simply labelled as “voluntarily donations from citizens”. The semantic switch may whitewash sourcing from both death-row prisoners and prisoners of conscience. China can gain credibility only by enacting new legislation prohibiting use of prisoner organs and by making its organ sourcing system open to international inspections. Until international ethical standards are transparently met, sanctions should remain. (shrink)

Despite the fact that the role of learning is recognised in empirical and theoretical work on sense of agency , the nature of this learning has, rather surprisingly, received little attention. In the present study we consider the contribution of associative mechanisms to SoA. SoA can be measured quantitatively as a temporal linkage between voluntary actions and their external effects. Using an outcome blocking procedure, it was shown that training action–outcome associations under conditions of increased surprise augmented this temporal linkage. (...) Moreover, these effects of surprise were correlated with schizotypy scores, suggesting that individual differences in higher level experiences are related to associative learning and to its impact on SoA. These results are discussed in terms of models of SoA, and our understanding of disrupted SoA in certain disorders. (shrink)

This article introduces some of the key philosophical contributions of W. E. B. Du Bois. Du Bois studied with Santayana and William James (among others), but chose social science, social theory, journalism, and activism over academic philosophy. Despite this detour, the philosophic depth of his work has won the attention of scholars in fields such as history, English, post‐colonial theory, African‐American Studies, American philosophy, and Africana philosophy, and it has belatedly begun to attract the interest of philosophers more generally. This (...) brief overview will explore the philosophical dimensions of some of Du Bois’s best‐known positions – his claims about the ‘color line’ and the Talented Tenth, his argument with Booker T. Washington, and his account of double‐consciousness. These positions open onto a rich constellation of views in social ontology, epistemology, political theory, existential phenomenology, and more besides. (shrink)

Was W. E. B. Du Bois a pragmatist? Does it matter? This essay argues that reading Du Bois as a pragmatist highlights aspects of his work and life that might otherwise go unnoticed, while also highlighting aspects of pragmatism that often go unappreciated. In addition, this double revelation may help restore to us some important resources for dealing with current social problems.

Black political actors across the ideological and organizational spectrum have routinely used expressive culture to do their work and advance their causes. However, the proper relationship between cultural and political work has remained controversial, with different views becoming ascendant in different traditions and communities, and at different times within the same traditions and communities. This chapter addresses some questions register in the black aesthetic tradition. It explores W. E. B. Du Bois's iconic arguments about art and propaganda by translating the (...) arguments into the language of more or less mainstream Anglophone academic philosophy. Political questions about matters other than autonomy come to mind when one studies black aesthetics. Notions like authenticity, solidarity, identity, ownership, and memory loom large in this tradition, and each has its own web of connections to questions of power, justice, citizenship, and freedom.

BackgroundAlthough the number of reporting guidelines has grown rapidly, few have gone through an updating process. The STARD statement (Standards for Reporting Diagnostic Accuracy), published in 2003 to help improve the transparency and completeness of reporting of diagnostic accuracy studies, was recently updated in a systematic way. Here, we describe the steps taken and a justification for the changes made.ResultsA 4-member Project Team coordinated the updating process; a 14-member Steering Committee was regularly solicited by the Project Team when making critical (...) decisions. First, a review of the literature was performed to identify topics and items potentially relevant to the STARD updating process. After this, the 85 members of the STARD Group were invited to participate in two online surveys to identify items that needed to be modified, removed from, or added to the STARD checklist. Based on the results of the literature review process, 33 items were presented to the STARD Group in the online survey: 25 original items and 8 new items; 73 STARD Group members (86 %) completed the first survey, and 79 STARD Group members (93 %) completed the second survey.Then, an in-person consensus meeting was organized among the members of the Project Team and Steering Committee to develop a consensual draft version of STARD 2015. This version was piloted in three rounds among a total of 32 expert and non-expert users. Piloting mostly led to rewording of items. After this, the update was finalized. The updated STARD 2015 list now consists of 30 items. Compared to the previous version of STARD, three original items were each converted into two new items, four original items were incorporated into other items, and seven new items were added.ConclusionsAfter a systematic updating process, STARD 2015 provides an updated list of 30 essential items for reporting diagnostic accuracy studies.

Formal dialectic has its roots in ancient dialectic. We can trace this influence in Charles Hamblin’s book on fallacies, in which he introduced his first formal dialectical systems. Earlier, Paul Lorenzen proposed systems of dialogical logic, which were in fact formal dialectical systems avant la lettre, with roles similar to those of the Greek Questioner and Answerer. In order to make a comparison between ancient dialectic and contemporary formal dialectic, I shall formalize part of the Aristotelian procedure for Academic (...) debates. The resulting system will be compared (1) with Van Eemeren and Grootendorst’s system of rules of Critical Discussion (the pragma-dialectical discussion procedure), which must, however, first itself be reconstructed as a formal dialectical system, and (2) with a Hamblin-type system, and (3) a Lorenzen-type system. When drawing comparisons, it will become clear that there is a line to be drawn from Aristotle to formal dialectic and pragma-dialectics, extending to contemporary computational models of argument.

[Wilfrid Hodges] During the last forty or so years it has become popular to offer explanations of logical notions in terms of games. There is no doubt that many people find games helpful for understanding various logical phenomena. But we ask whether anything is really 'explained' by these accounts, and we analyse Paul Lorenzen's dialogue foundations for constructive logic as an example. The conclusion is that the value of games lies in their ability to provide helpful metaphors and representations, (...) rather than in any true conceptual analysis. In fact some of the standard explanations of logical notions in terms of competitive games simply don't work. /// [ Erik C. W. Krabbe] In an attempt to redeem the Lorenzen-type dialogues from their detractors, it is perhaps best first to provide a survey of the various benefits these dialogues have been supposed to yield. This will be done in Section I. It will not be possible, within the confines of this paper, to scrutinize them all, but in Section II we shall delve deeper into the capacity of this type of dialogue to yield a model for the immanent criticism of philosophical positions. Section III will extend the concept of a dialogue in such a way as to conform better with our intuitive conceptions of what a rational discussion of a position should contain. This will be followed up by a concept of 'winning a dialogue' that takes position midway between the old conception of 'winning one play' and that of the full-fledged presentation of a winning strategy. Concepts of 'rational discussion' are thus shown to be, plausibly, more fundamental than those of proof. In Section IV, I shall discuss the specific problems about dialogical foundations put forward by Wilfrid Hodges. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 249 Girolamo Balduino: Ricerche sulla logica della Scuola di Padova nel Rinascimento. By Giovanni Papuli. (Bark Lacerta, Universith di Bari, Pubblicazioni dell'lstituto di filosofia, 12, 1967. Pp. 313. no price.) The philosophers at the University of Padua during the late Middle Ages and Renaissance arc attracting much renewed interest. This study makes accessible again the logical philosophy of Girolamo Balduino, professor at Padua during the second quarter (...) of the sixteenth century. Like other thinkers of his period, 13alduino follows the logic of Aristotle, and looks for progress within the ancient and mediaeval tradition, not for radically new doctrines. He continues the traditional interpretation of Aristotle by Averroes, for whom logic is only an instrumental habitus, a tool or method of demonstration. About the final contribution of the school of Padua to the improvement of Aristotelian logic was the doctrine of regressive demonstration, where demonstration terminates in or discloses the definition. Zabarella's well-known teaching on this point seems to be derived entirely from Balduino. Contrary to the interpretation of Cassirer, followed by Randall, this regressive demonstration is not a universal method of inquiry and is not at all like, and not the historical source of, the new method of Galileo. Papuli's book is solidly based on the original Latin texts, in notes, which are of great value in view of the fact that Balduino's works have been out of print since 1573. Not all of Papuli's interpretations are beyond criticism (e.g., p. 296), but he has done a service in enabling us to reestablish contact with one of the last significant commentators on Aristotle's logic. PAUL J. W. MILLER University of Colorado Documents sur la vie de Jules-Cdsar Vanini de Taurisano. By Emile Namer. (Bari: Adriatica Editrice, n.d.=Univcrsith degli Studi di Bari, Pubblicazioni delFIstituto di Filosofia, II serie, Testi e Documenti, I. Pp. 196+22 facsimile illustrations) Giulio Cesare Vanini (1585-1619) ranks with Giordano Bruno as a modern hero of freedom of philosophical expression. He was tortured and then burned at the stake in Toulouse at the age of thirty-four, because of the unorthodoxy of his views. For this reason, he has drawn more attention than is perhaps deserved on the basis of his rather mediocre writings, which are little more than a tissue of plagiarisms culled from Pomponazzi, Cardano, J. C. Scaliger, and others. In this volume, Emile Namer has collected the scattered documents dealing with Vanini's life and activities. This is a valuable service, for it should enable scholars to disentangle fact from fiction and reality from myth. There has been so much heated discussion regarding Vanini that it is now time that someone should attempt to establish the precise facts and to reevaluate Vanini's place in intellectual history. In the past, writings about him have been governed more often by emotion than by reason. Namer prints documents from Naples, London, Paris, Simancas, and Toulouse. Some of these have been printed before in various journal articles, but it is valuable to have them all together in a single volume. In addition, he prints relevant excerpts concerning--as one of them put it--le douzi~me apostre de Satan, including material from Mersenne, Garasse, and others. He also includes a series of facsimiles of sample pages from the documents which he prints. All in all Namer's work is competently 250 HISTORY OF PHILOSOPHY done, though perhaps a bit more annotation to put the documents in historical perspective would have been desirable. In any case this little volume must be one of the bases for any future serious biographical or interpretative studies dealing with Vanini. Moreover, it shouM also be useful for scholars dealing with more general questions of seventeenth-century intellectual, religious, and social history. Unfortunately, there is no index, nor bibliography of earlier literature on Vanini, and the Introduction is perhaps too brief to orient the reader who has little previous knowledge of Vanini.
