Focusing primarily on papers and books discussing the evolutionary and systematic interpretation of the Cambrian animal fossils from the Burgess Shale fauna, this paper explores the role of epistemic values in the context of a discipline striving to establish scientific authority within a larger domain of epistemic problems and issues . The focal point of this analysis is the repeated claims by paleontologists that the study of fossils gives their discipline a unique ‘historical dimension’ that makes it possible (...) for them to unravel important aspects of evolution invisible to scientists who study the extant biosphere. The first part of the paper explores the shifting of emphasis in the writings of paleontologists between two strategies that employ opposing views on the classical positivist and physicalist ideal of science. The second part analyzes paleontologists’ claims of privileged access to life’s historical dimension in a situation where a theoretical upheaval occurring independent of the epistemical problem at hand completely shifts the standards for evaluating the legitimacy of various knowledge claims. Though the various strategies employed in defending the privileged historical perspective of paleontology have been disparate and, to an extent contradictory, each impinges on the acceptance of a specific epistemic ideal or set of values and success or failure of each depends on the compatibility of this ideal with the surrounding community of scientists.

Stephen Jay Gould's Wonderful Life is a study of the fossils of the Burgess Shale of British Columbia. My concern is with the morals that Gould draws, with the ?new picture of life? that, he says, the reinterpreted Burgess animals compel. I conclude that his case is not established. (1) There may have been reasons to do with ?fitness? why most of the Burgess animals left no descendants, even if we cannot guess exactly what they were. (...) (2) We do not know that our past is dotted with the kind of mass extinctions that are needed for the random evolution that he proposes. (3) Even if what happened does rest on random variation and largely random selection, it does not follow that there are no standing forms that will be constantly re?instantiated. If Rational Life, in particular, is not special, then we have no right to think the world we experience bears any remote resemblance to a putative real world. (4) Even if there are no such forms, the fact that nothing in the state of things required us to exist is no good reason to say that No one requires us to. What Gould says does count against a simple progressivism, but not against an older and more orthodox theology. It also has implications for the Search for Extra?Terrestrial Intelligence (SETI).

The Burgess Shale, a set of fossil beds containing the exquisitely preserved remains of marine invertebrate organisms from shortly after the Cambrian explosion, was discovered in 1909, and first brought to widespread popular attention by Stephen Jay Gould in his 1989 bestseller Wonderful life: The Burgess Shale and the nature of history. Gould contrasted the initial interpretation of these fossils, in which they were ‘shoehorned’ into modern groups, with the first major reexamination begun in the 1960s, (...) when the creatures were perceived as ‘weird wonders’, possessing unique body plans and unrelated to modern organisms. More recently, a third phase of Burgess Shale studies has arisen, which has not yet been historically examined. This third phase represents a revolutionary new understanding, brought about, I believe, by a change in taxonomic methodology that led to a new perception of the Burgess creatures, and a new way to comprehend their relationships with modern organisms. The adoption of cladistics, and its corollary, the stem group concept, has forged a new understanding of the Burgess Shale … but has it also changed the questions we are allowed to ask about evolution?

Using the Burgess Shale controversies as a case-study, this paper argues that controversies within different domains may interact as to create a situation of "complicated intricacies," where the practicing scientist has to navigate through a context of multiple thought collectives. To some extent each of these collectives has its own dynamic complete with fairly negotiated standards for investigation and explanation, theoretical background assumptions and certain peculiarities of practice. But the intellectual development in one of these collectives may "spill (...) over" having far reaching consequences for the treatment of apparently independent epistemic problems that are subject of investigation in other thought collectives. For the practicing scientist it is necessary to take this complex web of interactions into account in order to be able to navigate in such a situation. So far most studies of academic science have had a tendency to treat the practicing scientist as members of a single (enclosed) thought collective that stands intellectually isolated from other similar entities unless the discipline was in a state of crisis of paradigmatic proportions. The richness and complexity of Burgess Shale debate shows that this encapsulated kind of analysis is not enough. (shrink)

The fossil record plays a key role in reconstructing deep evolutionary relationships through its documentation of the early diverging stem groups leading to extant phyla. In the middle Cambrian Burgess Shale, two famously problematic worms, Odontogriphus and Wiwaxia, have recently been reinterpreted as stem‐group molluscs based on their shared expression of a putative radula and putative ctenidia in Odontogriphus.1 More detailed analysis of these fossil structures, however, reveals pronounced anatomical and histological discrepancies with molluscan analogues, such that they (...) are more reliably interpreted as primitive features of the superphylum Lophotrochozoa. In the absence of any obviously derived characters, Odontogriphus could be placed in the stem group of the Lophotrochozoa or on the stem of any of its constituent phyla, whereas the dorsal covering of chaetae in Wiwaxia identifies it as a stem‐group polychaete. Despite their close relationship, these two jawed, segmented worms could conceivably represent the early stages of two separate phyla. BioEssays 28: 1161–1166, 2006. © 2006 Wiley Periodicals, Inc.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:For More than One Voice: Toward a Philosophy of Vocal ExpressionSarah K. Burgess and Stuart J. MurrayFor More than One Voice: Toward a Philosophy of Vocal Expression. Adriana Cavarero. Trans. Paul A. Kottman. Stanford: Stanford University Press, 2005. Pp. 262. $65.00, hardcover; $24.95, paperback.Adriana Cavarero's most recent book, For More than One Voice, offers the reader a critique of Western metaphysics that challenges the hegemony of speech's (...) relation to thought within politics. Revisiting Aristotle's Politics, Cavarero examines the famous definition of man as "zoon logon echon"—usually translated as "rational animal." She is critical of the tradition that renders logos here as "reason" or "rationality," modeled on the abstract and disembodied Platonic idea. Reading the Politics alongside the Poetics, she brings politics into a distinctly rhetorical sphere, and therefore figures logos as "phone semantike." In this light, man is a "speaking animal," an animal who speaks with a voice (phone) that is meaningful (semantike—an adjectival form that qualifies the voice itself). Cavarero's argument is that voice and meaning—phonic and semantic—must be sharply distinguished. The history of Western philosophy, she contends, has effaced this vital difference and focused instead on speech as a unitary phenomenon in which the vocalic and the semantic are always already joined as meaningful signification. In this way, the singularity of the vocalic itself has been elided in favor of speech that strongly privileges meaning. She therefore wishes to deliver us from language, as it were, through a recuperation of the force of the vocalic, the acoustic, the resonant and sonorous auditory quality of phone.Absent in the history of Western philosophy, this sonorous aspect of the vocalic stands as a corrective to our logocentric metaphysical tradition that singularly values the visual over the acoustic, semantic content over vocal utterances, and an abstract, anonymous "what" over a particular, embodied "who." Cavarero claims that the vocalic is an "anti-metaphysical" force that exceeds and challenges signification. In other words, the vocalic immediately communicates the uniqueness of the speaker without recourse to the signifying content of his or her speech. The voice is essentially relational—a relation that is described as "the condition of every communication.... the communicability of the communicable, or the significance of signification" (29). Indeed, for Cavarero the voice is that which "precedes, generates, and exceeds verbal communication" [End Page 166] (29–30). In this way, remarkably, Cavarero refigures the voice as a presymbolic origin that is both temporally and ontologically prior to signification, as that which is a condition of possibility for signification, and as that which is never exhausted by any signifying speech act as such.The voice is the expression of one unique, embodied individual to another. This expression, a "reciprocal invocation" founded in the sonorous, rhythmic, and resonant materiality of the voice, constitutes a "duet," a musical exchange of voices in and through which individuals mutually invoke one another. Cavarero resists inscribing such a relation within the symbolic realm; yet for her this relation is a "wordless language" that takes place in the paradigmatic scene between mother and infant. Here, in this originary scene, there is not yet the movement of language or speech as such, but the rhythm and cadence of demand and response—the voices of mother and infant that invoke one another. Drawing on Hélène Cixous's and Julia Kristeva's well-known work on the maternal chora, Cavarero demonstrates that the cadence of the "la-la melody" exchanged between mother and infant "configure[s] a reciprocal dependence" (170) that takes a structural form in the movement between demand and response.For Cavarero, the "scene of infancy" enjoys a primacy: it is both ontologically and chronologically prior to the institution of language and law. The maternal chora is figured as that which invisibly underwrites what will be understood as the law of the father—a law that is said to mark the inauguration of language. But if the law of the father is rational and semantic, the maternal should not be conceived as simply irrational and pure sound. For Cavarero, the maternal vocalic demonstrates its own reason through its rhythmic and musical resonance... (shrink)

What are the moral challenges that confront doctors as they manage healthcare institutions? How do we build trust in medical organisations? How do we conceptualize moral action? Based on accounts given by senior doctors from organisations throughout the UK, this book discusses the issues medical leaders find most troubling and identifies the moral tensions they face. Moral Leadership in Medicine examines in detail how doctors protect patients' interests, implement morally controversial change, manage colleagues in difficulty and rebuild trust after serious (...) medical harm. The book discusses how leaders develop moral narratives to make sense of these situations, how they behave while balancing conflicting moral goals and how they influence those around them to do the right thing in difficult circumstances. Based on empirical ethical analysis, this volume is essential reading for clinicians in leadership roles and students and academics in the fields of healthcare management, medical law and healthcare ethics"--Provided by publisher.

This paper is concerned with tracing the implications of two ideas as they affect quantum theory. One, which descends from Leibniz and Mach, is that there is no space-time continuum, but that which are involved are spacial and temporal relations involving the distant matter of the universe. The other is that our universe is finite. The picture of the world to which we are led is that of an enormous space-time Feynman diagram whose vertices are events. A consequence of finiteness (...) is that between each pair of events, along a world line, there can be only finitely many intermediate events. A further change is that we are no longer required to believe that particles need be anywhere between events. The paper takes up nonrelativistic quantum theory in a way that is consistent with these ideas. By considering analogies between the Wiener and the Feynman integrals, and between the Wiener process and related discrete processes, there is obtained a straightforward theory for the Feynman integral. Propagators are worked out for many of the cases relevant to the nonrelativistic theory.The paper shows that, even when there are, along each world-line, no more than one event per Compton wavelength, agreement is good with the usual Schrödinger theory.

In placing education at the centre, as The Main Enterprise of the World, Philip Kitcher has undertaken a monumental task. He has come to the field of philosophy of education captivated by the importance of its substantive preoccupations for the advancement of democratic aims. Accordingly, his book argues that the most salient obstruction to preparing citizens who will contribute to society is the seeming irreconcilability of the demands of industry, on the one hand, and of students’ personal growth, on the (...) other. In spite of his desire to accommodate diverse accounts of the human good, and his recognition of the formative role of culture, broadly conceived, there are strains in his account of human fulfilment deriving from the disjunction of the self and others. It is not evident, on his Deweyan onto-epistemology, that there is adequate attention to the imprint on an individual, and on the beliefs they come to form, of proximal social groups. The nature of the balance between ‘in-group’ and ‘out-group’ influences, between those that are near and those that are far, can profoundly affect the plausibility of Kitcher's account of a socially based sense of fulfilment.

The question, "Which modal logic is the right one for logical necessity?," divides into two questions, one about model-theoretic validity, the other about proof-theoretic demonstrability. The arguments of Halldén and others that the right validity argument is S5, and the right demonstrability logic includes S4, are reviewed, and certain common objections are argued to be fallacious. A new argument, based on work of Supecki and Bryll, is presented for the claim that the right demonstrability logic must be contained in S5, (...) and a more speculative argument for the claim that it does not include S4.2 is also presented.

This paper considers the implications of precautionary restrictions against technologies, in the context of the potential for creating and sustaining rumours. It focuses on the restriction against mobile phone use at petrol stations, based on the rumour that a spark might cause an explosion. Rumours have been substantiated by precautionary usage warnings from mobile phone manufacturers, petrol station usage restrictions, and a general lack of technical understanding. Petrol station employees have themselves spread the rumour about alleged incidents, filling the information (...) gap about the basis for the restriction. (shrink)

In Michael Stingl argues that the legalization of euthanasia can be made reasonable social policy only in the context of healthcare reform to deliver primary- and community-based care. Stingl accepts that euthanasia and that includes not only pain, but He is not worried The failure of the healthcare system to adequately respond to the needs of people who are suffering with chronic or terminal conditions may lead competent people to elect euthanasia. Stingl argues that it is the institutionalization of care (...) for dying people that reduces their ability to find meaning in prolonged life, and thereby makes it more attractive to consider ending one's life sooner. Options such as palliative care at home that significantly improve quality of life and make euthanasia less attractive are currently only available to those who can privately subsidize healthcare services. If an emphasis is placed on community-based initiatives and well-supported self-help, then there would be less inequality of healthcare and the voluntariness of choices, including euthanasia, would be more equal for all people under the healthcare system.

Dummett's case against platonism rests on arguments concerning the acquisition and manifestation of knowledge of meaning. Dummett's arguments are here criticized from a viewpoint less Davidsonian than Chomskian. Dummett's case against formalism is obscure because in its prescriptive considerations are not clearly separated from descriptive. Dummett's implicit value judgments are here made explicit and questioned. ?Combat Revisionism!? Chairman Mao.

This is the first systematic survey of modern nominalistic reconstructions of mathematics, and for this reason alone it should be read by everyone interested in the philosophy of mathematics and, more generally, in questions concerning abstract entities. In the bulk of the book, the authors sketch a common formal framework for nominalistic reconstructions, outline three major strategies such reconstructions can follow, and locate proposals in the literature with respect to these strategies. The discussion is presented with admirable precision and clarity, (...) and should be accessible even to readers with only minimal background in logic and mathematics. There will be many who will turn directly to these pages and use them as a brief manual on the state of the art of nominalism in mathematics. But the most intriguing parts of this elegant book—at least in my view—are the introduction and the conclusion, where the authors examine the significance of reconstructive nominalism. (shrink)

Computability and Logic has become a classic because of its accessibility to students without a mathematical background and because it covers not simply the staple topics of an intermediate logic course, such as Godel's incompleteness theorems, but also a large number of optional topics, from Turing's theory of computability to Ramsey's theorem. This 2007 fifth edition has been thoroughly revised by John Burgess. Including a selection of exercises, adjusted for this edition, at the end of each chapter, it offers (...) a simpler treatment of the representability of recursive functions, a traditional stumbling block for students on the way to the Godel incompleteness theorems. This updated edition is also accompanied by a website as well as an instructor's manual. (shrink)

That the result of flipping quantifiers and negating what comes after, applied to branching-quantifier sentences, is not equivalent to the negation of the original has been known for as long as such sentences have been studied. It is here pointed out that this syntactic operation fails in the strongest possible sense to correspond to any operation on classes of models.

After a summary of earlier work it is shown that elementary or Kalmar arithmetic can be interpreted within the system of Russell's Principia Mathematica with the axiom of infinity but without the axiom of reducibility.

Charles Mills posits an epistemology of ignorance that underwrites the complicity of Whites, or people of Western European descent, as signatories of the racial contract. There is prevailing discourse about the complicity of White persons in perpetuating racism and whether they can experience epistemic injustice. In this paper, the claim to hermeneutical injustice, in particular, makes a further assertion that moral blameworthiness is mitigated for a subcategory of White Americans because of being socialized into a White-dominant culture of caste-based Afroscepticism. (...) I argue, based on Peirce's conceptualization of doubt, as against Descartes, that Afroscepticism is a totalizing belief system predicated on a racial group-based social epistemology and maintains a settled stance of questioning the commensurate citizenship of Blacks or American descendants of slaves. These perceived social costs warrant educational interventions that can dismantle its reasoning architecture. White Afroscepticism poses a barrier to the teacher’s efforts to cultivate the democratic habitus in students; however, educator preparation that takes its existence into account can build on the standard classroom practices of critical social justice that promote equity, critical multicultural education, and critical thinking.

Venn diagrams, which are widely used in introductory logic courses, provide a convenient and illuminating way of presenting the various theories concerning the nature of law. When combined with the Aristotelian square of opposition, these diagrams show not only how the theories are related to one another, logically, which is essential to understanding them, but also which theories are compossible. One surprising result of this approach is that it shows the substantive compatibility of the theories of law set forth by (...) H. L. A. Hart and Ronald Dworkin, who are usually pitted against one another. I show, through quotation and visual representation, that there is no essential disagreement between these jurisprudential stalwarts concerning the relation of law and morality. (shrink)

Democratic deliberation places the burden of self‐governance on its citizens to provide mutual justifying reasons (Gutmann & Thompson, 1996). This article concerns the limiting effect that group identity has on the efficacy of democratic deliberation for equality in education. Under conditions of a powerful majority, deliberation can be repressive and discriminatory. Issues of white flight and race‐based admissions serve to illustrate the bias of which deliberation is capable when it fails to substantively take group identity into account. As forms of (...) Gilbert's (1994) plural subjects, identity group members holding the group identity can experience agency as the freedom to believe together with members of their group. I argue that attending to how group members acquire group beliefs through trust is a reasonable accommodation of group identity in deliberation. (shrink)

This fourth edition of one of the classic logic textbooks has been thoroughly revised by John Burgess. The aim is to increase the pedagogical value of the book for the core market of students of philosophy and for students of mathematics and computer science as well. This book has become a classic because of its accessibility to students without a mathematical background, and because it covers not simply the staple topics of an intermediate logic course such as Godel's Incompleteness (...) Theorems, but also a large number of optional topics from Turing's theory of computability to Ramsey's theorem. John Burgess has now enhanced the book by adding a selection of problems at the end of each chapter, and by reorganising and rewriting chapters to make them more independent of each other and thus to increase the range of options available to instructors as to what to cover and what to defer.

Botswana’s history is one of an unwavering exercise of self-determination and quest for self-rule. Post-independence, self-government prioritized an overarching philosophy of Kagisano or social harmony within which the aims of education were framed, in conjunction with a political commitment to Botho through democracy. For economic and social reasons the current educational policy of Botswana is driven by outcome-based education (OBE), with its metrics of quantifiable outcomes. This article argues that Olúfemi Táíwò’s analysis of decolonization provides a philosophical lens through which (...) to interpret Botswana’s current educational pathway within the prevailing decolonization discourse. OBE clearly exhibits features of neocolonialism, as it pertains to the national value principles. We draw on Ndlovu-Gatsheni’s decolonial epistemic perspective to frame the discussions. Insofar as OBE can be integrated with Botswana’s ethnically inclusive, community-based view of democracy and associated virtues, this is a worthy goal for education, and it could lead to a particular form of indigenized democracy. Substantive distinctions among the concepts of decolonization, neocolonialism, and decoloniality underwrite this thesis. We see the project of envisaging a future of education in Botswana as having to do with disentangling colonialist–imperialist cultural reproduction from indigenous aspirations. (shrink)
