This paper considers combinations of frictionless mechanical amplifiers arranged in a cycle so that the amplified signal passes around through an endless chain of such systems the output of the last system being fed into the first. It appears that while each amplifier may be reversible in the absence of friction, the effect of the combination is such that the signal would be unable to pass around the cycle indefinitely, using the same energy over and over again. It is felt (...) that the assumptions upon which this cycle is based are related to some of the conditions met with in consideration of open thermodynamic systems such as heat engines and living organisms when in finite environments.

The concepts of time and identity seem at once unproblematic and frustratingly difficult. Time is an intricate part of our experience -- it would seem that the passage of time is a prerequisite for having any experience at all -- and yet recalcitrant questions about time remain. Is time real? Does time flow? Do past and future moments exist? Philosophers face similarly stubborn questions about identity, particularly about the persistence of identical entities through change. Indeed, questions about the metaphysics of (...) persistence take on many of the complexities inherent in philosophical considerations of time. This volume of original essays brings together these two essentially related concepts in a way not reflected in the available literature, making it required reading for philosophers working in metaphysics and students interested in these topics. The contributors, distinguished authors and rising scholars, first consider the nature of time and then turn to the relation of identity, focusing on the metaphysical connections between the two, with a special emphasis on personal identity. The volume concludes with essays on the metaphysics of death, issues in which time and identity play a significant role. This groundbreaking collection offers both cutting-edge epistemological analysis and historical perspectives on contemporary topics.

Of the four types of biological control, (1) natural, (2) conservation, (3) augmentation, and (4) importation), ethical concerns have been raised almost exclusively about only one type: importation. These concerns rest largely on fears of extinction of animal species. Importation biological control is a cost-effective alternative to chemical control for basic food crops of resource-poor farmers. Regarding the other types of biological control, natural biological control is not consciously manipulated by humans. Augmentation has some technical concerns, but is generally an (...) environmentally-sound, viable alternative to chemicals and offers local employment. Conservation can help empower farmers to preserve native species, while saving labor and money and reducing chemical insecticides. (shrink)

DOES ARISTOTLE’S PHILOSOPHY rule out evolution? The short answer is “Yes, but...!”; the long answer: “No,... however!” Summarizing his excellent account of the reasoning which led Aristotle in book 7 of the Metaphysics to identify substance in the first place with specific form, W. K. C. Guthrie, in the final volume of his monumental history of Greek philosophy, concluded: “Doubtless this is not a satisfactory explanation of reality. For one thing it makes Darwinian evolution impossible.” The matter, needless to say, (...) is not quite so simple. Two questions are immediately raised: Does the doctrine of substantial form necessarily exclude evolution? If so, is this of itself sufficient reason for us to reject form? With these questions in mind, I propose. (shrink)

The placozoan Trichoplax adhaerens is a tiny hairy plate and more simply organized than any other living metazoan. After its original description by F.E. Schulze in 1883, it attracted attention as a potential model for the ancestral state of metazoan organization, the “Urmetazoon”. Trichoplax lacks any kind of symmetry, organs, nerve cells, muscle cells, basal lamina, and extracellular matrix. Furthermore, the placozoan genome is the smallest (not secondarily reduced) genome of all metazoan genomes. It harbors a remarkably rich diversity of (...) genes and has been considered the best living surrogate for a metazoan ancestor genome. The phylum Placozoa presently harbors three formally described species, while several dozen “cryptic” species are yet awaiting their description. The phylogenetic position of placozoans has recently become a contested arena for modern phylogenetic analyses and view‐driven claims. Trichoplax offers unique prospects for understanding the minimal requirements of metazoan animal organization and their corresponding malfunctions. (shrink)

The placozoan Trichoplax adhaerens has been bridging gaps between research disciplines like no other animal. As outlined in part 1, placozoans have been subject of hot evolutionary debates and placozoans have challenged some fundamental evolutionary concepts. Here in part 2 we discuss the exceptional genetics of the phylum Placozoa and point out some challenging model system applications for the best known species, Trichoplax adhaerens.

Awarding rights to rivers, forests, and other environmental entities (EEs) is a new and increasingly popular approach to environmental protection. The distinctive feature of such rights of nature (RoN) legislation is that direct duties are owed to the EEs. This paper presents a novel rebuttal of the strongest argument against RoN: the no interest argument. The crux of this argument is that because EEs are not sentient, they cannot possess the kinds of interests necessary to ground direct duties. Therefore, they (...) cannot be legitimate rights-bearers. After considering and rejecting standard responses to this argument, the paper challenges its fundamental assumption: that rights-correlative duties must be grounded in the interests of the rights-bearer. The paper then presents the RoN critic with a dilemma. The critic must either accept that EEs are legitimate rights-bearers, or delegitimise many well-established rights-bearers along with EEs. Either way, the no interest argument loses its force. (shrink)

One of the major contributions which Christopher Hookway has made to pragmatist epistemology is a critical exploration of the role that affective dispositions play in inquiry. According to Hookway, a well-functioning rational inquirer must rely upon a set of pre-reflective and affective dispositions which are not themselves fully available to rational evaluation. Despite their pre-reflective nature, on the pragmatist account these affective dispositions provide us with judgments and evaluations which are in many cases more reliable than those provided by explicit (...) rational reflection. -/- This chapter presents and defends Hookway’s account of the epistemic importance of our affective dispositions. The first section presents three roles which affective dispositions play within inquiry. The second section considers the concern that affective dispositions should be considered impositions upon our epistemic agency. In response, Hookway suggests that we must identify with our affective dispositions, and two interpretations of this claim are offered. The third section considers the possibility that the confidence we have in our affective dispositions might be appropriately shaken if we recognize that they are not shared by other inquirers. The chapter concludes by suggesting that Hookway’s position can overcome this worry by developing his notion of critical self-trust in three distinct ways. (shrink)

Abstract In this essay, I critically discuss a theory of utterance content and de re communication that Anne Bezuidenhout has recently developed in a series of articles. This theory regards the significance of utterances as more pragmatic in nature than allowed by traditional accounts; further, it downplays logical considerations in explaining de re communication, choosing instead to emphasize its psychological character. Included among the implications of this approach is the rejection of what can be called ?common content?, or utterance content (...) that is held in common by speaker and listener. After describing this theory, I argue that Bezuidenhout does not supply a compelling reason to prefer her account of utterance content over more traditional alternatives that make room for elements of content held in common between speaker and listener. Further, I argue that her account of de re communication supplies even more reason to reject the view of content to which she subscribes. In the end, it will be clear that she has no principled reason for rejecting common content. (shrink)

Few of us are free of all prejudices, however subtle and subconscious, and they may affect both patient care and teaching. Here I use reflection about a patient with HIV infection, from the points of view of two doctors caring for him and the patient himself, to explore prejudice against lifestyles that are considered “dangerous”. The paper then goes on to discuss research about physicians' attitudes to such cases, the teaching of ethics in a clinical environment and the need to (...) support junior medical staff. (shrink)

Like Saint Paul, I was “born out of due time” insofar as the study of bioethics is concerned. I spent 15 years in teaching and administration at the Aquinas Institute of Theology, then in Dubuque, Iowa, now on the campus of Saint Louis University. I was given a sabbatical study year in 1972–1973 to refresh my mind and spirit. Though my major study and research emphasis prior to the sabbatical study had been in the field of Church law and religious (...) government, I determined to direct my attention to the study of moral theology and ethics, because at that time there was confusion in this area of discipline, especially insofar as the Catholic community was concerned. With this in mind, I chose the University of Chicago as the locale for my study and was awarded a postdoctoral fellowship. (shrink)

Social studies of interdisciplinary science investigate how scientific collaborations approach complex challenges that require multiple disciplinary perspectives. In order for collaborators to meet these complex challenges, interdisciplinary collaborations must develop and maintain integrative capacity, understood as the ability to anticipate and weigh tradeoffs in the employment of different disciplinary approaches. Here we provide an account of how one group of interdisciplinary fog scientists intentionally catalyzed integrative capacity. Through conversation, collaborators negotiated their commitments regarding the ontology of fog systems and the (...) methodologies appropriate to studying fog systems, thereby enhancing capabilities which we take to constitute integrative capacity. On the ontological front, collaborators negotiated their commitments by setting boundaries to and within the system, layering different subsystems, focusing on key intersections of these subsystems, and agreeing on goals that would direct further investigation. On the methodological front, collaborators sequenced various methods, anchored methods at different scales, validated one method with another, standardized the outputs of related methods, and coordinated methods to fit a common model. By observing the process and form of collaborator conversations, this case study demonstrates that social studies of science can bring into critical focus how interdisciplinary collaborators work toward an integrated conceptualization of study systems.

This book suggests that the umbrella academic organizations step forward and draft a model code of ethics for the profession of higher education.

Meeting grand challenges requires responses that constructively combine multiple forms of expertise, both academic and non-academic; that is, it requires cross-disciplinary integration. But just what is cross-disciplinary integration? In this paper, we supply a preliminary answer by reviewing prominent accounts of cross-disciplinary integration from two literatures that are rarely brought together: cross-disciplinarity and philosophy of biology. Reflecting on similarities and differences in these accounts, we develop a framework that integrates their insights—integration as a generic combination process the details of which (...) are determined by the specific contexts in which particular integrations occur. One such context is cross-disciplinary research, which yields cross-disciplinary integration. We close by reflecting on the potential applicability of this framework to research efforts aimed at meeting grand challenges. (shrink)

In this article we argue that philosophy can facilitate improvement in cross-disciplinary science. In particular, we discuss in detail the Toolbox Project, an effort in applied epistemology that deploys philosophical analysis for the purpose of enhancing collaborative, cross-disciplinary scientific research through improvements in cross-disciplinary communication. We begin by sketching the scientific context within which the Toolbox Project operates, a context that features a growing interest in and commitment to cross-disciplinary research (CDR). We then develop an argument for the leading idea (...) behind this effort, namely, that philosophical dialogue can improve cross-disciplinary science by effecting epistemic changes that lead to better group communication. On the heels of this argument, we describe our approach and its output; in particular, we emphasize the Toolbox instrument that generates philosophical dialogue and the Toolbox workshop in which that dialogue takes place. Together, these constitute a philosophical intervention into the life of CDR teams. We conclude by considering the philosophical implications of this intervention. (shrink)

Are there natural kinds of things around which our theories cut? The essays in this volume offer reflections by a distinguished group of philosophers on a series of intertwined issues in the metaphysics and epistemology of classification.

Changes in environmental context between encoding and retrieval often affect explicit memory but research on implicit memory is equivocal. One proposal is that conceptual but not perceptual priming is influenced by context manipulations. However, findings with conceptual priming may be compromised by explicit contamination. The present study examined the effects of environmental context on conceptual explicit and implicit memory . Explicit recall was reduced by context change. The implicit test results depended on test awareness . Among test-unaware participants, priming was (...) equivalent for same-context and different-context groups, whereas for the test-aware, the same-context group produced more priming. Thus, when explicit contamination is controlled, changes in environmental context do not impair conceptual priming. Context dependency appears to be a general difference between implicit and explicit memory rather than a difference between conceptual and perceptual implicit memory. Finally, measures of mood indicated no changes in affect across contexts, arguing against mood mediation for the context effects in explicit recall. (shrink)

À la croisée de la philosophie et de l’histoire de l’art, Bernard Teyssèdre a ouvert des champs de recherche très divers, ce qui a suscité l’enthousiasme de ses étudiants, mais aussi déconcerté ceux qui restaient attachés à leur pré carré disciplinaire. Présenter aujourd’hui son parcours intellectuel revient à faire redécouvrir certains de ses travaux oubliés en esthétique afin de montrer leur singularité et leur cohérence profondément hégélienne, bien que ses recherches aient pris des formes très différentes et abordés avec érudition (...) des domaines très éloignés les uns des autres. Sans oublier de situer philosophiquement des aspects moins connus de ses activités, littéraires, artistiques et aussi institutionnelles avec sa contribution déterminante au développement de la discipline esthétique et à l’introduction des arts plastiques à l’université. Ce panorama n’aurait pas été complet si n’était pas signalée la place de ses recherches en paléontologie restées longtemps secrètes et a priori fort éloignées de l’esthétique. Alors que Bernard Teyssèdre avait publié en 2007 une nouvelle édition de son Roman de l’Origine revue et augmentée (et que Thierry Savatier était sur le point de publier une nouvelle édition de L’Origine du monde, Histoire d’un tableau de Gustave Courbet ), Jean Da Silva lui apprit qu’une photographie du tableau exposé au musée d’Orsay avait circulé en France pendant une vingtaine d’années avant d’être publiée en 1953 dans des revues oubliées ; ce qui bouleversait l’idée que l’on avait encore en 2009 de la connaissance de ce tableau. S’ensuivit ensuite un jeu de piste à deux, sur le blog, par courriels et au téléphone. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.1 (2002) 41-62 [Access article in PDF] Pure of Heart: From Ancient Rites to Renaissance Plato Marjorie O'Rourke Boyle The philosopher who published Plato for Western thought praised him strangely. Marsilio Ficino commended his translation of the Phaedrus to his soul mate Iohannes Bessarion because in that dialogue Plato sought from God spiritual beauty. "When this gold was given to Plato by (...) God, it shone in him most brilliantly, because he was so pure in heart." The epithet "pure in heart" is not literally Ficino's diction: he wrote "in his Platonic bosom perfectly clean" (Platonico in sinu utpote mundissimo). 1 Although this philological variant insinuates his full meaning, the modern translation conveys his essential import. Ficino and Bessarion were both scholars and priests, convinced of the compatibility of Platonism with Christianity. The recipient of the letter, Bessarion, had defended the Phaedrusvigorously against protestations that, for promoting the criminal activity of pederasty, it was an obscene work of unchaste philosophy. "Love," he declared, "leads many to beatitude." 2 Ficino emphasized that "no one can attain beatitude, which consists in divine contemplation, unless he loves God ardently." 3 To that end he translated the complete works of Plato into Latin with commentaries. He also composed a speculative Theologia platonica. The pair would have approved of the application to Plato of the gospel promise "Blessed are the pure of heart [hoi katharoi t¯e kardia], for they shall see God" (Matt. 5:8). Was this promise not already fulfilled in Plato, even before Jesus' pronouncement? Did not Socrates in the Phaedrus soar to the vision of God in his myth of the charioteer, where among privileged souls he peered over the rim of intelligible being to behold the divine processional and true being? The [End Page 41] myth figured the recollection of the soul's primordial state of innocence, "when we were pure ourselves," and, beholding "the beatific vision," were initiated into its "most blessed" mystery. 4 Bessarion cited the passage defensively, declaring Socrates' speech "most holy." 5The beatitudes, from which "pure of heart" derived, emphatically comprised the opening discourse of Jesus' Sermon on the Mount. Jesus blessed the poor in spirit, the mourners, the meek, those hungry and thirsty for righteousness, the merciful, the pure of heart, the peacemakers, and those persecuted for righteousness. He pronounced a corresponding good for each type (Matt. 5:1-10). The first four beatitudes promised reversals for the unfortunate; the second four, eschatological rewards for the virtuous. 6 Ficino personalized the beatitudes. He applied them in a letter to an archbishop to his own contrasting status as a priest "of humble fortune." Indicating his slight financial means, he affirmed obedience to his lot, even contentment with his meager possessions. He then wielded the divine reversal of human judgment, so startling in the beatitudes, against his enemies. "I am certainly content with few possessions, even though I am often held in contempt by many; for these many ought to be deemed of little worth. Blessed are the poor in spirit. Blessed are the peacemakers." 7Ficino also philosophized the beatitudes. He argued in Theologia platonica that, although the celestial realm was usually considered fiery, it could be earthy, as poets imagined the Elysian Fields. Jesus' beatitude promising the possession of the earth to the meek was proof. Ficino expounded the nine grades of celestial beatitude as a belief shared by Platonists and Christians. He assigned these grades to varying degrees and combinations of three ends: the fear of divine power, the search for wisdom, and the love of good, which ultimately transformed the soul. This elaborate division Ficino compared to Jesus' beatitudes. "I think that this mystery is signified in the gospel, where the divine oracle nine times calls his disciples blessed, because through nine grades of merit, with God leading, the nine heavens are sought blessedly through nine degrees of contemplation." Despite his philosophical imposition on the biblical text, Ficino qualified his syncretism. The gospel admonished the dismissal of philosophical meanderings to pursue... (shrink)
