For the last couple of years, The Hastings Center has been running a research project titled “The Ethical Issues of Synthetic Biology” (funded by the Alfred P. Sloan Foundation) that is focused primarily on whether the prospect of altering microorganisms to meet human ends is intrinsically troubling. “Synthetic biology” is not necessarily limited to the alteration of microorganisms, but the applications now under development—such as yeast that produce a precursor of the antimalarial drug artemisinin or blue-green algae that produce fuel—are (...) certainly limited to that. A set of essays in this issue of the Report features a variety of different takes on the field. For the last six months of the project .. (shrink)

The release of genetically engineered organisms into the shared environment raises scientific, ethical, and societal issues. Using some form of democratic deliberation to provide the public with a voice on the policies that govern these technologies is important, but there has not been enough attention to how we should connect public deliberation to the existing regulatory process. Drawing on lessons from previous public deliberative efforts by U.S. federal agencies, we identify several practical issues that will need to be addressed if (...) relevant federal agencies are to undertake public deliberative activities to inform decision‐making about gene editing in the wild. We argue that, while agencies may have institutional capacity to undertake public deliberative activities, there may not be sufficient political support for them to do so. Advocates of public deliberation need to make a stronger case to Congress about why federal agencies should be encouraged and supported to conduct public deliberations. (shrink)

Despite the salient experience of encoding threatening events, these memories are prone to distortions and often non-veridical from encoding to recall. Further, threat has been shown to preferentially disrupt the binding of event details and enhance goal-relevant information. While extensive work has characterised distinctive features of emotional memory, research has not fully explored the influence threat has on temporal memory, a process putatively supported by the binding of event details into a temporal context. Two primary competing hypotheses have been proposed; (...) that threat can impair or enhance temporal memory. We analysed two datasets to assess temporal memory for an in-person haunted house experience. In study 1, we examined the temporal structure of memory by characterising memory contiguity in free recall as a function of individual levels of heart rate as a proxy of threat. In study 2, we replicated marginal findings of threat-related increases in memory contiguity found in study 1. We extended these findings by showing threat-related increases in recency discriminations, an explicit test of temporal memory. Together, these findings demonstrate that threat enhances temporal memory regarding free recall structure and during explicit memory judgments. (shrink)

In Beyond Physicalism, an interdisciplinary group of physical scientists, behavioral and social scientists, and humanists from the Esalen Institute’s Center for Theory and Research argue that physicalism must be replaced by an expanded scientific naturalism that accommodates something spiritual at the heart of nature.

We examine the notion of conditionals and the role of conditionals in inductive logics and arguments. We identify three mistakes commonly made in the study of, or motivation for, non-classical logics. A nonmonotonic consequence relation based on evidential probability is formulated. With respect to this acceptance relation some rules of inference of System P are unsound, and we propose refinements that hold in our framework.

Classical or Patañjala Yoga diagnoses die human conditon as state of suffering caused by ignorance whose specific form is misidentification of self with psychophysical nature. This paper argues that liberation in Yoga is healing in an ultimate sense, i.e., attainment of well-being with respect to the person's fundamental nature and soteriological potential. Vyāsa's Yogabhasya presents the yogic remedy in terms of a medical model, and this paper excavates the therapeutic paradigm of the Yogasūtras using concept of health distilled from the (...) Āyurvedic medical text Caraka-saṁhitā. Determinants of health according to Āyurveda include wholeness, self-identit), and freedom, and these concepts are utilized to ground the claim that in classical Yoga, liberation is healing: curing the dysfunction and consequent suffering of one's psychophysical self, which is coextensive with realization of one's true Self as consciousness.

Recent advances in philosophical thinking about consciousness, such as cognitive phenomenology and mereological analysis, provide a framework that facilitates using computational models to explore issues surrounding the nature of consciousness. Here we suggest that, in particular, studying the computational mechanisms of working memory and its cognitive control is highly likely to identify computational correlates of consciousness and thereby lead to a deeper understanding of the nature of consciousness. We describe our recent computational models of human working memory and propose that (...) three computational correlates of consciousness follow from the results of this work: itinerant attractor sequences, top-down gating, and very fast weight changes. Our current investigation is focused on evaluating whether these three correlates are sufficient to create more complex working memory models that encompass compositionality and basic causal inference. We conclude that computational models of working memory are likely to be a fruitful approach to advancing our understanding of consciousness in general and in determining the long-term potential for development of an artificial consciousness specifically.

This essay introduces a special report from The Hastings Center entitled Democracy in Crisis: Civic Learning and the Reconstruction of Common Purpose, which grew out of a project supported by the John S. and James L. Knight Foundation. This multiauthored report offers wide‐ranging assessments of increasing polarization and partisanship in American government and politics, and it proposes constructive responses to this in the provision of objective information, institutional reforms in government and the electoral system, and a reexamination of cultural and (...) political values needed if democracy is to function well in a pluralistic and diverse society. The essays in the special report explore the norms of civic learning and institutions, social movements, and communal innovations that can revitalize civic learning in practice. This introductory essay defines and explains the notion of civic learning, which is a lynchpin connecting many of the essays in the report. Civic learning pertains to the ways in which citizens learn about collective social problems and make decisions about them that reflect the duties and responsibilities of citizenship. Such learning can occur in many social settings in everyday life, and it can also be facilitated through participation in the processes of democratic governance on many levels. Civic learning is not doctrinaire and is compatible with a range of public goals and policies. It is an activity that increases what might be called the democratic capability of a people. (shrink)

Moral values in healthcare range widely between interest groups and are principally subjective. Disagreements diminish dialogue and marginalize alternative viewpoints. Extremely premature births exemplify how discord becomes unproductive when conflicts of interest, cultural misunderstanding, constrained evidence review, and peculiar hierarchy compete without the balance of objective standards of reason. Accepting uncertainty, distributing risk fairly, and humbly acknowledging therapeutic limits are honorable traits, not relativism, and especially crucial in our world of constrained resources. We think dialogics engender a mutual understanding that: (...) i) transitions beliefs beyond bias, ii) moves conflict toward pragmatism (i.e., the truth of any position is verified by subsequent experience), and iii) recognizes value pluralism (i.e., human values are irreducibly diverse, conflicting, and ultimately incommensurable). This article provides a clear and useful Point-Counterpoint of extreme prematurity controversies, an objective neurodevelopmental outcomes table, and a dialogics exemplar to cultivate shared empathetic comprehension, not to create sides from which to choose. It is our goal to bridge the understanding gap within and between physicians and bioethicists. Dialogics accept competing relational interests as human nature, recognizing that ultimate solutions satisfactory to all are illusory, because every choice has downside. Nurturing a collective consciousness via dialogics and pragmatism is congenial to integrating objective evidence review and subjective moral-cultural sentiments, and is that rarest of ethical constructs, a means and an end.

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

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)

Plato's Euthyrphro, Apology, andCrito portray Socrates' words and deeds during his trial for disbelieving in the Gods of Athens and corrupting the Athenian youth, and constitute a defense of the man Socrates and of his way of life, the philosophic life. The twelve essays in the volume, written by leading classical philosophers, investigate various aspects of these works of Plato, including the significance of Plato's characters, Socrates's revolutionary religious ideas, and the relationship between historical events and Plato's texts.

Intellectual humility, which entails openness to other views and a willingness to listen and engage with them, is crucial for facilitating civil dialogue and progress in debate between opposing sides. In the present research, we tested whether intellectual humility can be reliably detected in discourse and experimentally increased by a prior self-affirmation task. Three-hundred and three participants took part in 116 audio and video-recorded group discussions. Blind to condition, linguists coded participants’ discourse to create an intellectual humility score. As expected, (...) the self-affirmation task increased the coded intellectual humility, as well as participants’ self-rated prosocial affect (e.g., empathy). Unexpectedly, the effect on prosocial affect did not mediate the link between experimental condition and intellectual humility in debate. Self-reported intellectual humility and other personality variables were uncorrelated with expert-coded intellectual humility. Implications of these findings for understanding the social psychological mechanisms underpinning intellectual humility are considered. (shrink)

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

In lieu of an abstract, here is a brief excerpt of the content:WORKS OF FICTION AND ILLOCUTIONARY ACTS by Gregory Currie ii O peech act theory is remarkably unhelpful in explaining what ficOtion is." So says Kendall Walton.1 My purpose here is to showjust how wrong diis judgment is. Not that I want to endorse all die attempts there have been to connect fiction with the notion of a speech act. Elsewhere I have argued diat the most prominent attempt (...) at such a theory, the one due to John Searle, fails.2 But my complaint is not mat Searle employs the idea of a speech act; rather it is that he employs it in too half-hearted a fashion. The idea of Searle and odiers is diat to write fiction is not to perform a speech act, but rather to pretend to do so. I, on the odier hand, take the view that the writer of fiction engages in an act of speech diat is distinctively fictional, and distinctively different from speech acts such as asserting, requesting, questioning, and so forth. What follows is a much simplified account of this idea.3 Following die program of Strawson and Grice, I believe diat the different kinds of speech acts are to be individuated in terms of the utterer's intentions.4 The intention of the one who asserts is to get a certain kind of response; perhaps to get the audience to believe the proposition asserted.5 The one who commands wants the audience to obey, die requester wants the audience to answer, etc. And in all these cases the utterer intends to get the response partly as a result of the audience's recognition of diat very intention. (This is the familiar Gricean mechanism.) The utterer of fiction, on the odier hand, wants to get the audience to make-believe die proposition uttered.6 Thus we have an act structurally similar to 304 Gregory Currie305 paradigmatic speech acts like asserting, commanding, and requesting (die structural similarity being given by the use in all cases of the Gricean intention ), but differing from diese odiers with respect to die content of the utterer's intention. Let us call such an act a.fictive illocutionary act. Pursuing this line in more detail leads to an intuitively satisfactory taxonomy of speech acts which places the uttering (usually writing) of fiction fully widiin die purview of the theory, rather dian shutting it off to one side as a pseudo-performance, as widi Searle. Is such a theory susceptible to the objections diat Walton brings? Walton is quite right to say (and here I suppose he has Searle in mind) that fiction is not simply the absence ofillocutionary force: "it is something positive, something special" (p. 79). As already indicated, my theory gives a positive account of fiction as a special kind of speech act. But Walton presses the issue further by suggesting that the essence of fiction has nodiing to do with die absence of assertive force. It is possible, he says, "to make an assertion by writing fiction." His point is not merely that fictional stories are sometimes told in order to get across some serious but not explicit point — everyone can agree to that. It is rather diat fictional works contain explicit assertions — e.g., some of Tolstoy's sentences about Napoleon in War and Peace — and that a fiction might contain nothing but assertions. He imagines a genre of historical fiction in which "authors are allowed no liberties with the facts, and in which they are understood to be asserting as fact whatever they write" (p. 80). Let us grant that this is a possibility. What, dien, would distinguish a piece of fiction belonging to this genre from, say, a work of historical scholarship? The answer comes when we see that the same utterance can be used to perform more than one illocutionary act. Thus if I say to someone "I have no money" it may be that I want him both to believe that I have no money and to give me the goods on credit. And in both cases I intend to get die desired responses via his recognition of my intentions. The same utterance can count both as an assertion... (shrink)

Henry Kyburg’s lottery paradox (1961, p. 197) arises from considering a fair 1000 ticket lottery that has exactly one winning ticket. If this much is known about the execution of the lottery it is therefore rational to accept that one ticket will win. Suppose that an event is very likely if the probability of its occurring is greater than 0.99. On these grounds it is presumed rational to accept the proposition that ticket 1 of the lottery will not win. Since (...) the lottery is fair, it is rational to accept that ticket 2 won’t win either—indeed, it is rational to accept for any individual ticket i of the lottery that ticket i will not win. However, accepting that ticket 1 won’t win, accepting that ticket 2 won’t win, . . . , and accepting that ticket 1000 won’t win entails that it is rational to accept that no ticket will win, which entails that it is rational to accept the contradictory proposition that one ticket wins and no ticket wins.

Preface/Introduction: The question under discussion is metaphysical and truly elemental. It emerges in two aspects — how did we come to be conscious of our own existence, and, as a deeper corollary, do existence and awareness necessitate each other? I am bold enough to explore these questions and I invite you to come along; I make no claim to have discovered absolute answers. However, I do believe I have created here a compelling interpretation. You’ll have to judge for yourself. -/- (...) What follows is the presentation of three essays I have worked on over the past several years seeing publication for the first time. “Hollows of Experience” was written first as an invited chapter for a collection on the ontology of consciousness. However, when cuts became necessary, my chapter got the knife. Its length has prohibited it from publication in any print journal. “Myth and Mind” was written next as a journal article, but as my involvement with it grew so did its length, so it has also idled on my websty awaiting its call. “From Panexperientialism to Conscious Experience” was written most recently, but it is the only one to have been available to the public elsewhere than my own website. Under the name, “The Continuum of Experience”, it was Target Article #95 on the recently closed Karl Jaspers Forum (for discussion purposes only). -/- I have put them in a different sequence here, for reasons of logical sense. Up first, “Panexperientialism” deals with an idea difficult for many to accept, namely that conscious experience is a particular mode of symbolically reflected experience that is largely unique to our species. However, I aver that experienced sensation in itself (as found, for example, in autonomic sensory response systems) goes “all the way down” into nature, and thus the title, panexperientialism. -/- Understanding this idea is helpful to dealing with the focus on language in Part I of “Hollows”, next, since here speech and general symbolic interaction in general are found to be the catalysts for the creation of our consciously experienced world (our “lived reality”). In Part II, however, I explore how experienced sensations must be coeval with existence, and, with even greater temerity, how all this sensational existence might have arisen within some literally inconceivable background of awareness-in-itself that yet has a dynamism that occasionally breaks into existence as experiential events and entities. (The latter may sound wacky, but physicists and cosmologists are themselves attempting to come to terms with that which seethes with vast potential energy in what they refer to as the quantum vacuum.) -/- “Myth and Mind” was put third since it deals with a major lacuna in “Hollows” — that presumed prehistoric period when members of our species made the painful crossing of the symbolic threshold into the beginnings of cultural consciousness. Speech plays a central role here, too, but I look more at narrative structures from the dawn of self-awareness when ritual and myth became vital to human survival. Why would fantastic stories and bizarre rituals be necessary? I speculate that growing foresight led to the unavoidable realization of certain mortality, from which, in turn, emerged the secondary realization that we were now alive. In contrast to our yet-to-come death, we have life here and now, and by ritually identifying with a symbolically expanded mythic, i.e., sacred, reality, we may continue to live on after bodily death, just as our ancestors and loved ones must also do. Language and mythmaking are necessary to avoid mortal despair and they remain at the core of human consciousness. -/- As Ernst Cassirer (1944) has noted, language and myth are “twin creatures”, both metaphoric webs over a reality we can never wholly comprehend. We live in the symbolic and construct our works of imagination and wars of conquest to make life meaningful, to feel immortal, and to sense that we ourselves participate in a reality greater than ourselves. No doubt we do, but this does not mean our culturally constructed self-identities survive the death of our bodies, and it does not imply that our symbolic concepts can ever indicate the ultimate truth. We simply must symbolize an extended reality that was sacred to our ancestors: “Is it not our way, as illusory as it may be, to force continuance on our world and our life in the face of their inevitable ending? Are we not compelled to extend those imaginary horizons as far as we can despite the terror and the sometime joy their extension incites? Is their closure not a form of death?” (Crapanzano, p. 210) -/- Of course, this leaves me in the uncomfortable position of being forced to admit that this venture of mine must inevitably be another attempt at meaningful mythmaking. But what else could it be? This is certainly not a scientific proof though it is indeed an academically rigorous exploration. (Just try to count the citations!) I hope the reader will judge my thesis on the basis of its coherence, the sense of meaning it evokes, my intellectual responsibility, and, finally, the engagement it inspires. If you have read my expositions and found yourself immersed in the timeless questions I here call forth, I would call these writings successful (even if you violently disagree with my answers). -/- I am very grateful to Huping Hu for granting me this special issue of JCER in which to present my ideas in some detail. He has patiently dealt with my exuberant approach and allowed the many changes I kept coming up with right until the final publication date. I also wish to thank the many potential commentators who politely replied to my invitation, and, even more, I thank those who made time to write actual commentaries. -/- References -/- Cassirer, E.

In lieu of an abstract, here is a brief excerpt of the content:RUSSELL TO FREGE, 24 MAY 1903: "I BELIEVE I HAVE DISCOVERED THAT CLASSES ARE ENTIRELY SUPERFLUOUS" GREGORY LANDINI Philosophy / University of Iowa Iowa City, IA 52242, USA It was his consideration of Cantor's proof that there is no greatest cardinal, Russell recalls in My Philosophical Development, that led in the spring of 1901 to the discovery of the paradox of the class of all classes not members (...) of themselves. "Never glad confident morning again", were Whitehead's reported words (MPD, p. 58). Whitehead was, of course, wrong. Russell had many new confident mornings. One in particular apparently occurred on 19 May 1903. On 23 May Russell wrote in his journal: "Four days ago 1 solved the Contradiction -the relief of this is unspeakable" (Papm 12: 24). The "solution" was communicated to Whitehead, who responded by telegram: "Heartiest congratulations Aristoteles secundus. 1 am delighted" (Clark, p. III). But it was not long before Russell knew his proposal was inadequate. On the form he would scrawl: "A propos of solVing the Contradiction. [But the solution was wrong]" (ibid; Russell's brackets). The episode is intriguing. What was the proposal? Russell's correspondence with Frege sheds some light. On 20 October 1902 Frege had sent a letter suggesting a way to avoid the contradiction. Frege's suggestion, formulated in a great hurry so that it might appear in the Appendix of Vol. II of the Grundgesetze der Arithmetik, was to abandon his Basic Law V; zcj>z =zez. ==. (x)(x. ==. ex), and to replace it by Russell to Frege, 24 May I903 161 V' zz =zez. ==. (x)(x *zz & x* zez: ~ : x. ==. ex). The underlying idea was to accept that one concept may have the same extension as another even though the two concepts are not coextensive. Though he thought the underlying idea "probably correct",! Russell expressed reservation in a reply of 12 December:... I find it difficult to accept your solution even though it is probably correct. Do you deny, e.g., that all classes form a class? And if this is admitted, then it is possible that - ana. Moreover, the class of non-humans is a. non-human. Otherwise it must be admitted that not ail objects fall either under a or not-a; namely, if a is a range of values, then a fails neither under a nor under not-a. This contradicts the law of excluded middle, which will be inconvenient to say the least.2 (Frege I980, p. 151) Frege's response of 28 December does not mention the contradiction, and Volume II of his Grundgesetze appeared early in 1903. Russell's reservations concerning Frege's solution· continue in a letter to Frege of 20 February 1903: What you say about my contradiction is of the greatest interest to me. Do you believe that the range of values remains unchanged if some subclass of the class is assigned to it as a new member? Extension seems to fit this view better than intension. Bur I fe;el far from clear about this question. (Frege I980, p. 155) Frege replied on 21 May, explaining that in general a class does not remain unchanged when a particular subclass is added to it, but that two concepts may have the same extension (the same class) when the only difference between them is that this class falls under the first concept but not under the second (p. 157). Then on 24 May 1903 Russell excitedly wrote Frege of a solution of the paradox of classes: "I received your letter this morning, and 1 am replying to it at once, for russell: the Journal of the Berrrand Russdl Archives McMasrer University Library Press n.S.•2 (wincer 1992-93): 160-85 ISSN 0036-01631 • The same evaluation appears in Russell's Appendix to The Principles ofMathematics (p. 522). 2 Frege's '\- a II b" is Peano and Russell's "a E b". Russell should have put "~ana". 162 GREGORY LANDINI I believe I have discovered that classes are entirely superfluous. Your designation i(z) can be used for itself, and x E i(z) for (x).... this seems to me to avoid the contradiction" (p. 159). The proposal is also mentioned in a... (shrink)

Each sentence is supposed to say that for every natural number kz greater than n, the k-th sentence on the list is not true. By comparing Yablo’s construction to an analogous construction with early Russellian propositions, we show that Yablo has failed to generate a paradox. 1. vicious circularity in yablo’s paradox S elf-reference has been taken to be the source of paradoxes. Poincaré and Russell are commonly associated with this thesis. In an amusing passage, the mathematician Jourdain recalls something of the dialogue between them: Nearly all mathematicians agreed that the way to solve these paradoxes was simply not to mention them; but there was some divergence of opinion as to how they were to be unmentioned. It was clearly unsatisfactory merely not to mention them. Thus Poincaré was apparently of the opinion that the best way of avoiding such awkward subjects was to mention that they were not to be mentioned.

Douglas Lackey (London: Allen & Unwin, 1973), p. 196. 3 I believe that this is Russell’s view in 1906. See Gregory Landini, “Russell’s Separation of the Logical and Semantic Paradoxes”, Revue internationale de philosophie 58 (2004): 257–94 (issue titled “Russell en héritage / Le centenaire des Principes”, ed. Philippe de Rouilhan). a long nose, say: ‘When I speak of noses, I except such as are inordinately long’, which would not be a very successful eTort to avoid a painful topic.”1 Poincaré maintained that one should exclude the oTending cases and therebyavoid“viciouscircles”ofself-referencewhichgenerateparadoxes. Russell objected: We may illustrate this by what M. Poincaré says concerning Richard’s paradox. Having Wrst put E = “all numbers deWnable in a Wnite number of words” we arrive at a paradox, due, says M. Poincaré, to our having included a number only deWnable in a Wnite number of words by means of E. This vicious circle he proposes to avoid by deWning E as “all numbers deWnable in a Wnite number of words without mentioning Ey”. To the uninitiated, this deWnition looks more circular than ever.2 Russell held that some paradoxes such as those of classes require, in order to exclude oTending cases without mentioning them, a “reconstruction of logical Wrst principles”. Others, such as Richard’s, are to be dismissed because they involve confused and viciously circular notions of “deWnability ”.3 Is self-reference necessary for paradoxes? The question is not well crafted. There are quite diTerent notions ofz “self-reference” involved in paradoxes. The self-reference involved in the Liar “This sentence is false” is provided by an apparatus of indexicals. This apparatus is quite distinct from the self-reference involved in Russell’s early ontology of propositions (as mind- and language-independent states of aTairs). This is an ontological self...

For better than  years, his papers have given (...) perhaps the most clear and authoritative account of the complex intellectual and personal journey of Wittgenstein. The collection of these important papers in one book is an outstanding gift to all who are interested in early analytic philosophy. The papers are not presented diachronically, but topically, starting with McGuinness’s discussions of the interplay between Wittgenstein’s philosophy and his conception of himself, as Austrian patriot, as teacher, as Jew, as architect, as penitent. There is much controversy in all of this. It is upsetting to learn that Wittgenstein remarked (likely sometime shortly after the events of Pearl Harbor in ) that “Things will be terrible when the war is over, whoever wins. Of course very terrible if the Nazis won, but terribly slimy if the Allies win” (p. ). In spite of McGuinness’s attempts at charitable explanation, it is hard to excuse this remark. Wittgenstein should have recognized that it was imperative that the Allies win, for surely he could not, by then, have been blind to the pogroms of Nazism (if not the implementation of their Final Solution to the Jewish question). It is just disappointing to discover Wittgenstein’s dalliance with anti-Semitism or with Weininger’s deplorable Sex and Gender. Nonetheless, McGuinness offers a wonderful and balanced portrait of Wittgenstein with a welcome minimum of hyperbole either concerning his genius, achievements and influences, or his eccentricities and failings.  As also in McGuinness’s Wittgenstein, a Life: Young Ludwig (London: Duckworth, and Berkeley : U. of California P., ; reprinted as Young Ludwig: Wittgenstein’s Life, – with a new Preface [Oxford: Clarendon P., ]) russell: the Journal of Bertrand Russell Studies n.s.  (winter –): – The Bertrand Russell Research Centre, McMaster U.  - _Russell_ journal (home office): E:CPBRRUSSJOURTYPE2502\REVIEWS.252 : 2006-02-27 11:52  Reviews In a second part, the book delves into the origins and nature of Wittgenstein ’s Tractatus Logico-Philosophicus. Since the papers in this part do not come diachronically, it would be nice for each to have a date by its title, so that if there is an historical development of McGuinness’s ideas it could be more easily tracked. But evolving or not, the interpretations in McGuinness’s papers are of the very highest quality. I know of no one else who has come closer to unravelling the often cryptic entries in the Tractatus. Though some of McGuinness’s assumptions about Russell’s philosophy are now challenged by new interpretations —in particular, it seems that Russell never held a theory of types of entities —there remain a great many gems in these papers. Among them are the following: Wittgenstein’s conception of solipsism is not Cartesian and epistemic, but concerns the limits of logical form and the proper ethical attitude towards life (p. ); the Notes on Logic were offered as satisfying the dissertation requirement for Wittgenstein’s .. degree (p. ); Wittgenstein included among the “logical constants” such notions as that of a “predicate” and a “dual complex”, not just logical particles such as “not”, “or”, “all” and “some” (p. ); Wittgenstein’s Grundgedanke was independent of his “picture theory” (p. ); Wittgenstein’s “logical atomism” was to be a purified form of Russell’s so that it forms “true logical atomism” with no differences of type and with the unification provided by neutral monism of mental and physical particulars (p. ); Wittgenstein and Russell had similar attractions to Spinozistic ethics, the conception of the world sub specie aeternitatis and the “mystical” as what inspires the scientific attitude (pp. , ); Hertz’s elimination of the concept of “force” in physics was an inspiration for Wittgenstein’s elimination of “classes”, “probability”, and the logical constants (p. ); structured variables were central to Wittgenstein’s Tractarian programme (p. ); Wittgenstein’s conception of philosophical analysis has important ties to Kuhn’s concept of a paradigm (pp. , , ).

The COVID-19 pandemic has affected every human being on the planet and forced us all to reflect on the bioethical issues it raises. In this timely book, Gregory Pence examines a number of relevant issues, including the fair allocation of scarce medical resources, immunity passports, tradeoffs between protecting senior citizens and allowing children to flourish, discrimination against minorities and the disabled, and the myriad issues raised by vaccines.

Now in its twentieth year of publication, this rich collection, popular among teachers and students alike, provides an in-depth look at major cases that have shaped the field of medical ethics. The book presents each famous (or infamous) case using extensive historical and contextual background, and then proceeds to illuminate it by careful discussion of pertinent philosophical theories and legal and ethical issues.

Borovik proposed an axiomatic treatment of Morley rank in groups, later modified by Poizat, who showed that in the context of groups the resulting notion of rank provides a characterization of groups of finite Morley rank [2]. (This result makes use of ideas of Lascar, which it encapsulates in a neat way.) These axioms form the basis of the algebraic treatment of groups of finite Morley rank undertaken in [1].There are, however, ranked structures, i.e., structures on which a Borovik-Poizat rank (...) function is defined, which are not ℵ0-stable [1, p. 376]. In [2, p. 9] Poizat raised the issue of the relationship between this notion of rank and stability theory in the following terms: “… ungroupede Borovik est une structure stable, alors qu'un univers rangé n'a aucune raison de l'être …” (emphasis added). Nonetheless, we will prove the following:Theorem 1.1.A ranked structure is superstable.An example of a non-ℵ0-stable structure with Borovik-Poizat rank 2 is given in [1, p. 376]. Furthermore, it appears that this example can be modified in a straightforward way to give ℵ0-stable structures of Borovik-Poizat rank 2 in which the Morley rank is any countable ordinal (which would refute a claim of [1, p. 373, proof of C.4]). We have not checked the details. This does not leave much room for strenghthenings of our theorem. On the other hand, the proof of Theorem 1.1 does give a finite bound for the heights of certain trees of definable sets related to unsuperstability, as we will see in Section 5. (shrink)

This book gather's thirty-five of Pence's most influential, groundbreaking, and personal essays into one broad-ranging volume. It included essays on cloning, AIDS, dignified death,and test-tube babies.

Human cloning raises the most profound questions about human nature, our faith in ourselves, and our ability to make decisions that could significantly alter the character of humanity. In this exciting and accessible book, Gregory Pence offers a candid and sometimes humorous look at the arguments for and against human cloning. Originating a human being by cloning, Pence boldly argues, should not strike fear in our hearts but should be examined as a reasonable reproductive option for couples. Pence considers (...) how popular culture has influenced the way we think about cloning, and he presents a lucid and non-technical examination of the scientific research and relevant moral issues in the cloning debate. This book is a must-read for anyone who is concerned about the impact of technology on human life and for those with interests in medical ethics, sociology, and public policy. (shrink)

Models of recognition memory have traditionally struggled with the puzzle of criterion setting, a problem that is particularly acute in cases in which items for study and test are of widely varying types, with differing degrees of baseline familiarity and experience (e.g., words vs. random dot patterns). We present a dynamic model of the recognition process that addresses the criterion setting problem and produces joint predictions for choice and reaction time. In this model, recognition decisions are based not on the (...) absolute value of familiarity, but on how familiarity changes over time as features are sampled from the test item. Decisions are the outcome of a race between two parallel accumulators: one that accumulates positive changes in familiarity (leading to an ‘‘old’’ decision) and another that accumulates negative changes (leading to a ‘‘new’’ decision). Simulations with this model make realistic predictions for recognition performance and latency regardless of the baseline familiarity of study and test items. (shrink)

A majority opinion seems to have emerged in scholarly analysis of the assortment of technologies that have been given the label “synthetic biology.” According to this view, society should allow the technology to proceed and even provide it some financial support, while monitor­ing its progress and attempting to ensure that the development leads to good outcomes. The near‐consensus is captured by the U.S. Presidential Commission for the Study of Bioethical Issues in its report New Directions: The Ethics of Synthetic Biology (...) and Emerging Technologies, which arguably marked the end of a preliminary round of analysis about the ethical and policy questions raised by synthetic bi­ology. Like a number of other, earlier documents issued by various groups around the world, the re­port called attention to questions about how the technology will be used; whether it might be mis­used; what sorts of accidents might happen along the way; the economic, environmental, and social impacts of the eventual applications; whether the very idea of “synthetic biology” should be trou­bling; and how the debate over all of these ques­tions will be conducted. Also like most similar documents, however, while it called for careful monitoring and oversight of technology, it did not recommend any significant new constraints on its development and use. The commission's stance was that it would be “imprudent either to declare a moratorium on synthetic biology until all risks can be determined and mitigated, or to simply ‘let science rip,’ regardless of the likely risks.”In this report, we will take stock of the current consensus, comment on some of the major points of disagreement, and identify the next steps for the debate. In part I, we offer a brief overview of the research and applications commonly grouped together under the heading of synthetic biology, partly in order to set the stage for the rest of the discussion and partly because we want to highlight some conceptual problems that attend the very la­bel given this field. In parts II, III, and IV, we take up, respectively, three broad classes of concerns that arise in the context of synthetic biology: con­cerns about the intrinsic or inherent value of do­ing synthetic biology, concerns about the concrete harms and benefits of doing synthetic biology, and concerns about justice. Addressing these concerns requires a method for bringing the public's values to bear on policy‐making concerning emerging biotechnologies; in part V, we discuss the chal­lenges in developing such a method.
