The realization that prokaryotes naturally and frequently disperse genes across steep taxonomic boundaries via lateral gene transfer gave wings to the idea that eukaryotes might do the same. Eukaryotes do acquire genes from mitochondria and plastids and they do transfer genes during the process of secondary endosymbiosis, the spread of plastids via eukaryotic algal endosymbionts. From those observations it, however, does not follow that eukaryotes transfer genes either in the same ways as prokaryotes do, or to a quantitatively similar degree. (...) An important illustration of the difference is that eukaryotes do not exhibit pangenomes, though prokaryotes do. Eukaryotes reveal no detectable cumulative effects of LGT, though prokaryotes do. A critical analysis suggests that something is deeply amiss with eukaryote LGT theories. In prokaryotes, genes from the environment can enter the genome via lateral gene transfer. In eukaryote genetics, natural variation comes from within the genome, not from the environment. Yet many reports claim that eukaryotes undergo LGT just like prokaryotes. Such claims do not withstand scrutiny and are probably untrue. (shrink)

The question concerning the meaning of life is important, but it immediately confronts the present authors with insurmountable obstacles from a philosophical standpoint, as it would require us to define not only what we hold to be life, but what we hold to be meaning in addition, requiring us to do both in a properly researched context. We unconditionally surrender to that challenge. Instead, we offer a vernacular, armchair approach to life’s origin and meaning, with some layman’s thoughts on the (...) meaning of origins as viewed from the biologist’s standpoint. One can observe that biologists generally approach the concept of biological meaning in the context of evolution. This is the basis for the broad resonance behind Dobzhansky’s appraisal that “Nothing in biology makes sense except in the light of evolution”. Biologists try to understand living things in the historical context of how they arose, without giving much thought to the definition of what life or living things are, which for a biologist is usually not an interesting question in the practical context of daily dealings with organisms. Do humans generally understand life’s meaning in the context of history? If we consider the problem of life’s origin, the question of what constitutes a living thing becomes somewhat more acute for the biologist, though not more answerable, because it is inescapable that there was a time when there were no organisms on Earth, followed by a time when there were, the latter time having persisted in continuity to the present. This raises the question of where, in that transition, chemicals on Earth became alive, requiring, in turn, a set of premises for how life arose in order to conceptualize the problem in relation to organisms we know today, including ourselves, which brings us to the point of this paper: In the same way that cultural narratives for origins always start with a setting, scientific narratives for origins also always start with a setting, a place on Earth or elsewhere where we can imagine what happened for the sake of structuring both the problem and the narrative for its solution. This raises the question of whether scientific origins settings convey meaning to humans in that they suggest to us from what kind of place and what kinds of chemicals we are descended, that is, to which inanimate things we are most closely related.

Metagenomics bears upon all aspects of microbiology, including our understanding of mitochondrial and eukaryote origin. Recently, ribosomal protein phylogenies show the eukaryote host lineage – the archaeal lineage that acquired the mitochondrion – to branch within the archaea. Metagenomic studies are now uncovering new archaeal lineages that branch more closely to the host than any cultivated archaea do. But how do they grow? Carbon and energy metabolism as pieced together from metagenome assemblies of these new archaeal lineages, such as the (...) Deep Sea Archaeal Group (including Lokiarchaeota) and Bathyarchaeota, do not match the physiology of any cultivated microbes. Understanding how these new lineages live in their environment is important, and might hold clues about how mitochondria arose and how the eukaryotic lineage got started. Here we look at these exciting new metagenomic studies, what they say about archaeal physiology in modern environments, how they impact views on host‐mitochondrion physiological interactions at eukaryote origin.

A recent study(1) of sequence data from many different proteins has suggested that contemporary prokaryotes and eukaryotes may have shared a common ancestor as recently as 2 billion years ago (the molecular clock). Strong evidence from the geological record, however, indicates that oxygen‐producing microorganisms, perhaps similar to modern cyanobacteria, existed 3.5 billion years ago. The fossil evidence, therefore, suggests that any common ancestor of prokaryotes and eukaryotes must have existed at least 1.5 billion years earlier than suggested by the molecular (...) clock evidence. The discrepancy between molecular and geological evidence for the age of modern cells is considered here, as are aspects of gene descent in the tree of life that might help to account for it.

Despite thermodynamic, bioenergetic and phylogenetic failings, the 81‐year‐old concept of primordial soup remains central to mainstream thinking on the origin of life. But soup is homogeneous in pH and redox potential, and so has no capacity for energy coupling by chemiosmosis. Thermodynamic constraints make chemiosmosis strictly necessary for carbon and energy metabolism in all free‐living chemotrophs, and presumably the first free‐living cells too. Proton gradients form naturally at alkaline hydrothermal vents and are viewed as central to the origin of life. (...) Here we consider how the earliest cells might have harnessed a geochemically created proton‐motive force and then learned to make their own, a transition that was necessary for their escape from the vents. Synthesis of ATP by chemiosmosis today involves generation of an ion gradient by means of vectorial electron transfer from a donor to an acceptor. We argue that the first donor was hydrogen and the first acceptor CO2. (shrink)

Planctomycetes, Verrucomicrobia and Chlamydia are prokaryotic phyla, sometimes grouped together as the PVC superphylum of eubacteria. Some PVC species possess interesting attributes, in particular, internal membranes that superficially resemble eukaryotic endomembranes. Some biologists now claim that PVC bacteria are nucleus‐bearing prokaryotes and are considered evolutionary intermediates in the transition from prokaryote to eukaryote. PVC prokaryotes do not possess a nucleus and are not intermediates in the prokaryote‐to‐eukaryote transition. Here we summarise the evidence that shows why all of the PVC traits (...) that are currently cited as evidence for aspiring eukaryoticity are either analogous (the result of convergent evolution), not homologous, to eukaryotic traits; or else they are the result of horizontal gene transfers.

This paper examines the relationship between university mission statements and sustainability practices by institutions of higher education. We examine mission statement constructs and the degree to which higher educational institutions meet specific sustainability criteria in line with the College Sustainability Report Card. Our sample consists of 347 universities from the Sustainable Endowment Institute's (2011) Green Report Card. Previous research suggests that mission statements are essential for superior organizational performance outcomes. We examine the relationship between university mission statement content and sustainability (...) practices. Findings indicate that the greater the number of specific terms used in the university mission statements, the higher the statistical likelihood that those universities had higher sustainability ratings. Findings also indicate that private institutions and nonreligious‐affiliated institutions are more likely to include sustainability constructs in their mission statements than colleges and universities with religious affiliation and public institutions. Several propositions to guide future research are discussed. (shrink)

Developing and applying a framework for understanding the complexities of economic and legal considerations in two recent Supreme Court rulings was the focus of this research. Of especial concern was the protection of intellectual property in the pharmaceutical industry. Two cases from 2013 were selected: FTC v. Activis and Association for Molecular Pathology v. Myriad Genetics, Inc.. Part of the rationale for the selection was the importance of the Supreme Court rulings and the importance of the pharmaceutical sector. A qualitative (...) content analysis of the Court’s reported decision in each case was analyzed. Since ethical considerations may or may not be consistent with efficiency considerations of plaintiffs, defendants, or the courts, both efficiency and ethical arguments were included. Equally important to the understanding of the economic and ethical issues in the two above- mentioned cases was the development of a rationale for including and excluding a variety of ethical theories, ultimately influenced by Markkula Center For Applied Ethics Of Santa Clara University and Schumann :93–111, 2001). The refinement and use of a levels analysis approach portrays societal, organizational, and individual impacts, and allows for deeper understanding of litigated cases, irrespective of the country in which the litigation takes place :385–393, 2004; Foss et al., J Manag Stud 47:455–482, 2010). A rationale for this framework is the societal and organizational impacts on the myriad of stakeholders in the pharmaceutical sector. We suggest that this framework can be applied to other industries and other complex conflicts among stakeholders as well. (shrink)

The origin and early evolution of animals marks an important event in life's history. This event is historically associated with an important variable in Earth history – oxygen. One view has it that an increase in oceanic oxygen levels at the end of the Neoproterozoic Era (roughly 600 million years ago) allowed animals to become large and leave fossils. How important was oxygen for the process of early animal evolution? New data show that some modern sponges can survive for several (...) weeks at low oxygen levels. Many groups of animals have mechanisms to cope with low oxygen or anoxia, and very often, mitochondria – organelles usually associated with oxygen – are involved in anaerobic energy metabolism in animals. It is a good time to refresh our memory about the anaerobic capacities of mitochondria in modern animals and how that might relate to the ecology of early metazoans. (shrink)

Martin Heidegger produced a comprehensive, highly original body of thought on art. He conceived of the work of art primarily as a projected place where art happens. For Heidegger, art is a largely linguistic process or an advent of truth, in the sense of a language-bound revealing of the Being of some being . Because art and language are essentially connected, the work of art is place, time and "Volk" specific. The work of art is, like its human author, (...) linguistically thrown into a particular or concrete historic World and is, thus, fundamentally bound to a specific historical people. Heidegger held that real or pure German art was superior, due to its grounding in the German language, and could help establish a new epoch of German greatness. His profoundly non-aesthetic, "volkish" and instrumentatist views on art, in general, and German art in particular, are close to Nazi "art politics" and can help make the case for establishing a philosophical basis for Heidegger's engagement with Naziism.

What is the proper relation between the scientific worldview and other parts or aspects of human knowledge and experience? Can any science aim at "complete coverage" of the world, and if it does, will it undermine--in principle or by tendency--other attempts to describe or understand the world? Should morality, theology and other areas resist or be protected from scientific treatment? Questions of this sort have been of pressing philosophical concern since antiquity. The Proper Ambition of Science presents ten particular case (...) studies written by prominent philosophers, looking at how this problem has been approached from the ancient world right up to the present day.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

William James catalogued an amazing diversity of religious experiences. Yet even the pluralistic James was able to find a nucleus, consisting of an uneasiness and its solution, ‘1. The uneasiness, reduced to its simplest terms, is a sense that there is something wrong about us as we naturally stand. 2. The solution is a sense that we are saved from the wrongness by making proper connection with the higher powers.’ But by stressing the moral factor, James seems to exclude (...) those who stress rather the sense of mystery stemming from man's theoretical limitations. Einstein, for example, writes: ‘The most beautiful thing we can experience is the mysterious side of life. It is the deep feeling which is at the cradle of all true art and science. In this sense, and only in this sense, I count myself amongst the most deeply religious people.’ For Einstein as for Pascal : ‘The last proceeding of reason is to recognise that there is an infinity of things which are beyond it.’ Thus I propose the following revision of James' conception of the nucleus of the religious experience: uneasy awareness of the limitations of man's moral or theoretical powers, especially when reality is restricted to sense data and natural objects; awe-full awareness of a further reality—beyond or behind or within; conviction that participation with this further reality is of supreme importance.

Most theories of learning consider inferring a function f from either observations about f or, questions about f. We consider a scenario whereby the learner observes f and asks queries to some set A. If I is a notion of learning then I[A] is the set of concept classes I-learnable by an inductive inference machine with oracle A. A and B are I-equivalent if I[A] = I[B]. The equivalence classes induced are the degrees of inferability. We prove several results about (...) when these degrees are trivial, and when the degrees are omniscient. (shrink)

The dominant unspoken philosophical basis of medical care in the United States is a form of Cartesian reductionism that views the body as a machine and medical professionals as technicians whose job is to repair that machine. The purpose of this paper is to advocate for an alternative philosophy of medicine based on the concept of healing relationships between clinicians and patients. This is accomplished first by exploring the ethical and philosophical work of Pellegrino and Thomasma and then by connecting (...) Martin Buber's philosophical work on the nature of relationships to an empirically derived model of the medical healing relationship. The Healing Relationship Model was developed by the authors through qualitative analysis of interviews of physicians and patients. Clinician-patient healing relationships are a special form of what Buber calls I-Thou relationships, characterized by dialog and mutuality, but a mutuality limited by the inherent asymmetry of the clinician-patient relationship. The Healing Relationship Model identifies three processes necessary for such relationships to develop and be sustained: Valuing, Appreciating Power and Abiding. We explore in detail how these processes, as well as other components of the model resonate with Buber's concepts of I-Thou and I-It relationships. The resulting combined conceptual model illuminates the wholeness underlying the dual roles of clinicians as healers and providers of technical biomedicine. On the basis of our analysis, we argue that health care should be focused on healing, with I-Thou relationships at its core. (shrink)

Analytic philosophy of existence in the 20th century and beyond has been dominated by two central claims. One is that existence is instantiation. The other is that there are no modes of existence. This article attempts to refute both claims.

George Grant for teaching today. While there are studies of Grant's political philosophy and theology, there is no sustained study of his teaching, and specifically its relation to his political philosophy and theology. No study to date has drawn extensively on the collected works--including talks to teachers and his D.Phil. thesis at Oxford--or upon his biography, the collected letters, and the vast secondary literature, all of which I cite extensively in this comprehensive and original study of the teachings of George Grant. Aside from its synoptic status--it can serve a reference book for students of Grant as well as textbook for students of education--original features include 1) the characterization of Grant as Progressive Christian Platonist, the first term an acknowledgement of his imprinting as a child and of his (inadvertent) affinities with John Dewey, 2) the linking of his critiques of time, teaching, and technology into one critique: idolatry, 3) an extension of his preference for Eastern Christianity and its emphasis upon icons, associated also with his study of Simone Weil, from whose work I quote, 4) the extension of Grant's critique through the elaboration of a concept of attunement, and 5) the explication of one of Grant's keywords: eternity, juxtaposed with time (the subject of Chapter 3). My teaching of Grant emphasizes its timeliness, accenting his prescience, identifying several educational issues today--academic vocationalism, educational technology, privatization of schooling, the ascendency of research over teaching--that Grant identified and critiqued fifty years ago. Grant's prescience is also demonstrated by his concerns over the fate of what he termed particularity within Canada and globally, worried that economic globalization will erase distinctive national histories and cultures. Replacing these would be a world state, universal and homogeneous, representing the worst tyranny humanity has known. Current issues of right-wing populism--notably in the U.K. and the U.S.--Grant foresaw as reactions against these historical tendencies. I conclude with a long epilogue wherein I review the main points and show Grant's profound pertinence for students today. (shrink)

Twelve essays in literary theory, philosophy, and religion--about atheism, freedom, and "the Jesus thought experiment"--connect, but don't conclude. A recurring theme is the "nothing" at the heart of the deep atheism of George Eliot, Walter Pater, Oscar Wilde, Rudyard Kipling, and Thomas Hardy, who approach "nothing" with a directness lacking in their English-speaking philosophical contemporaries. How does being in the world--Thomas Nagel's "what-it's-likeness"--and how do values--Alasdair MacIntyre's justice and misericordia--fare in the face of the mindless "It" that Hardy finds at (...) the heart of things? A pivotal essay compares the theism of Paul Ricoeur and the atheism of Daniel Dennett--the subtitle is a response to the latter's latest book. Writing and Freedom defends (a strong version of) free will as necessarily interpersonal: my freedom is nothing but my acceptance of yours. This is how Milton, Rossetti, and Dickinson treat their readers, and how scientists and philosophers ideally treat each other. The book's open-ended essays model freedom so understood. Moreover, both "nothing" and "freedom" are fundamental to biblical and religious narratives (Mark and Newman). God, being "out of all relation" with the finite, cannot be known from the text of the world. Yet as "nothing," God may be said to grant unconditional autonomy to his creatures, and therefore to be present in his absence. It is round "nothing," therefore, that atheists and theists endlessly circulate. But that is what the deep atheism of European thinkers--Nietzsche, Freud, Lacan, and Zizek--say we all do anyway, however excitedly we pretend to ourselves that we don't. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 34.1 (2001) 1-20 [Access article in PDF] On the Hegelian Sublime: Paul de Man's Judgment Call Martin Donougho In recent years, the sublime has become a focus of renewed interest in philosophy and literary theory, despite being (perhaps in part because it is) "the most confused and confusing notion of the time" (Honour 1977, 145). 1 Much of the interest has been directed at the (...) Kantian account and the long tradition stemming from it. By contrast, little attention has been paid to G. W. F. Hegel's version of the sublime, whether of the phenomenon itself or of its conceptualization. That is natural enough, it might be thought, given the marginal place accorded the sublime in Hegel's scheme of things--he simply was not interested. Yet, that very marginality is of interest, if we follow the lead of the subtlest of commentators, Paul de Man, in his essay "Hegel on the Sublime" (1983). As de Man reads and diagnoses it, Hegel's marginalizing of the sublime (much as with the section on symbolics or, indeed, aesthetics tout court) serves the interests of an aesthetic ideology. The gesture of putting the sublime aside in fact reveals more about the philosopher's system than is found in his express doctrine, de Man insists. The sublime, like Hegel's allegory, should then be read symptomatically, as the "defective cornerstone" of the entire system. 2 In this essay, I have two aims: besides explicating Hegel's theory of the sublime on its own terms, I try to assess de Man's reading of Hegel's rhetorical strategies.Even if de Man's charges fail--as I argue they do--his approach to Hegel remains, I think, full of insights. The sublime, it might well be thought, betokens the same penetration of an objective field by subjective theory that (for Heidegger and others) is at issue with Western metaphysics as a whole; a prime instance of this would be Hegel's own allegedly masterful project, including his attempt at an aesthetic system. So understood, "on the sublime" would translate as over the sublime, that is, in a bid to enframe and control discourse about "the most high" or "great writing" (see Longinus). 3 And then we might ask, for example, what Hegel is doing [End Page 1] when he consigns the sublime to a minor role, or when he instead gives the classical Ideal star billing. How exactly does he stage his discourse about art?Oddly enough, Hegel's sublime is not at all part of the main theoretical line stemming (if only in retrospect) from Immanuel Kant. That line might be dubbed "the Romantic sublime"--the title of an influential book by Thomas Weiskel, which appeared posthumously in 1976--or, alternatively, "the Yale sublime," in honor of an entire group (which includes Geoffrey Hartman and Harold Bloom) who wrote about the tendency of Romantics such as William Wordsworth and Ralph Waldo Emerson to invest themselves in their topic. 4 Kant himself points to a possible illusory move he labels subreption. Here--to apply a useful distinction Peter de Bolla (1989) draws--we have not just a discourse on, but also a discourse of the sublime. 5 The discourse of the sublime produces the very category it is meant to analyze, hence providing a space for "experience" of the sublime. A boot-strapping process induces a "subject-effect," calls forth a subject position. The remarkable thing is that--although he is said at sixteen to have made a translation of Longinus 6 and although he was, of course, familiar with the whole Kantian approach, which in many respects should have been congenial to him--Hegel stands apart from this "Romantic," or "hermeneutic," sublime. He does not at all give the appearance of staging readings in the manner sketched above, but instead adopts a distanced, disinterested perspective on the phenomenon.Even so, his aesthetic system might be accused of framing a discourse on the sublime, which, through seeking dialectical profit on its investment, shades into a discourse of the sublime. Thus, de... (shrink)

A discussion of Christian ethics focuses on the physician's image as a parent, warrior against death, expert, and teacher, and the oath that guides his or her practice.

Modern professionals wield considerable power by virtue of their knowledge. However, they also feel beleaguered by the constraints they face and the public disapproval they often experience. These pressures combine to diminish the professional's sense of public responsibility and convert him or her in self-perception to a careerist.

This article articulates and defends F. H. Bradley's regress argument against external relations using contemporary analytic techniques and conceptuality. Bradley's argument is usually quickly dismissed as if it were beneath serious consideration. But I shall maintain that Bradley's argument, suitably reconstructed, is a powerful argument, plausibly premised, and free of such obvious fallacies as petitio principii. Thus it does not rest on the question‐begging assumption that all relations are internal, as Russell, and more recently van Inwagen, maintain. Bradley does not (...) attack external relations in order to affirm a doctrine of internal relations, and his monism is not derived from the internality of all relations, but from the self‐contradictory nature of all relations. For Bradley, it is the “relational situation”as such that is ontologically defective. (shrink)

The doctrine of divine simplicity, according to which God is devoid of physical or metaphysical complexity, is widely believed to be incoherent. I argue that although two prominent recent attempts to defend it fail, it can be defended against the charge of obvious incoherence. The defense rests on the isolation and rejection of a crucial assumption, namely, that no property is an individual. I argue that there is nothing in our ordinary concepts of property and individual to warrant the assumption, (...) and that once the assumption is rejected, the way is clear to viewing the divine attributes as self-exemplifying properties whose self-exemplification entails their identity with an individual.
