Let NBG be von Neumann-Bernays-Gödel set theory without the axiom of choice and let NBGA be the modification which allows atoms. In this paper we consider some of the well-known class or global forms of the wellordering theorem, the axiom of choice, and maximal principles which are known to be equivalent in NBG and show they are not equivalent in NBGA.

The Fraenkel-Mostowski method has been widely used to prove independence results among weak versions of the axiom of choice. In this paper it is shown that certain statements cannot be proved by this method. More specifically it is shown that in all Fraenkel-Mostowski models the following hold: 1. The axiom of choice for sets of finite sets implies the axiom of choice for sets of well-orderable sets. 2. The Boolean prime ideal theorem implies a weakened form of Sikorski's theorem.

In 1945–46, representatives of the U.S. government made similar discoveries in both Germany and Japan, unearthing evidence of unethical experiments on human beings that could be viewed as war crimes. The outcomes in the two defeated nations, however, were strikingly different. In Germany, the United States, influenced by the Canadian physician John Thompson, played a key role in bringing Nazi physicians to trial and publicizing their misdeeds. In Japan, the United States played an equally key role in concealing information about (...) the biological warfare experiments and in securing immunity from prosecution for the perpetrators. The greater force of appeals to national security and wartime exigency help to explain these different outcomes. (shrink)

We study the relationship between the countable axiom of choice and the Tychonoff product theorem for countable families of topological spaces.

Two Fraenkel-Mostowski models are constructed in which the Boolean Prime Ideal Theorem is true. In both models, AC for countable sets is true, but AC for sets of cardinality 2math image and the 2m = m principle are both false. The Principle of Dependent Choices is true in the first model, but false in the second.

We investigate the set theoretical strength of some properties of normality, including Urysohn's Lemma, Tietze-Urysohn Extension Theorem, normality of disjoint unions of normal spaces, and normality of Fσ subsets of normal spaces.

We show that it is not possible to construct a Fraenkel-Mostowski model in which the axiom of choice for well-ordered families of sets and the axiom of choice for sets are both true, but the axiom of choice is false.

We find properties of topological spaces which are not shared by disjoint unions in the absence of some form of the Axiom of Choice.

The axiom of multiple choice implies that metric spaces are paracompact but the reverse implication cannot be proved in set theory without the axiom of choice.

In Zermelo-Fraenkel set theory with the axiom of choice every set has the same cardinal number as some ordinal. Von Rimscha has weakened this condition to “Every set has the same cardinal number as some transitive set”. In set theory without the axiom of choice, we study the deductive strength of this and similar statements introduced by von Rimscha.

We study the relationship between various properties of the real numbers and weak choice principles.

We study the Tychonoff Compactness Theorem for several different definitions of a compact space.

We provide a general criterion for Fraenkel–Mostowski models of $${\textsf{ZFA}}$$ (i.e. Zermelo–Fraenkel set theory weakened to permit the existence of atoms) which implies “every linearly ordered set can be well ordered” ( $${\textsf{LW}}$$ ), and look at six models for $${\textsf{ZFA}}$$ which satisfy this criterion (and thus $${\textsf{LW}}$$ is true in these models) and “every Dedekind finite set is finite” ( $${\textsf{DF}}={\textsf{F}}$$ ) is true, and also consider various forms of choice for well-ordered families of well orderable sets in these (...) models. In Model 1, the axiom of multiple choice for countably infinite families of countably infinite sets ( $${\textsf{MC}}_{\aleph _{0}}^{\aleph _{0}}$$ ) is false. It was the open question of whether or not such a model exists (from Howard and Tachtsis “On metrizability and compactness of certain products without the Axiom of Choice”) that provided the motivation for this paper. In Model 2, which is constructed by first choosing an uncountable regular cardinal in the ground model, a strong form of Dependent choice is true, while the axiom of choice for well-ordered families of finite sets ( $${\textsf{AC}}^{{\textsf{WO}}}_{{\textsf{fin}}}$$ ) is false. Also in this model the axiom of multiple choice for well-ordered families of well orderable sets fails. Model 3 is similar to Model 2 except for the status of $${\textsf{AC}}^{{\textsf{WO}}}_{{\textsf{fin}}}$$ which is unknown. Models 4 and 5 are variations of Model 3. In Model 4 $${\textsf{AC}}_{\textrm{fin}}^{{\textsf{WO}}}$$ is true. The construction of Model 5 begins by choosing a regular successor cardinal in the ground model. Model 6 is the only one in which $$2{\mathfrak {m}} = {\mathfrak {m}}$$ for every infinite cardinal number $${\mathfrak {m}}$$. We show that the union of a well-ordered family of well orderable sets is well orderable in Model 6 and that the axiom of multiple countable choice is false. (shrink)

This book is a collection of secondary essays on America's most important philosophic thinkers—statesmen, judges, writers, educators, and activists—from the colonial period to the present. Each essay is a comprehensive introduction to the thought of a noted American on the fundamental meaning of the American regime.

In set theory without the Axiom of Choice, we investigate the set-theoretic strength of the principle NDS which states that there is no function f on the set ω of natural numbers such that for everyn ∈ ω, f ≺ f, where for sets x and y, x ≺ y means that there is a one-to-one map g : x → y, but no one-to-one map h : y → x. It is a long standing open problem whether NDS implies (...) AC. In this paper, among other results, we show that NDS is a strong axiom by establishing that ACLO ↛ NDS in ZFA set theory. The latter result provides a strongly negative answer to the question of whether “every Dedekind-finite set is finite” implies NDS addressed in G. H. Moore “Zermelo’s Axiom of Choice. Its Origins, Development, and Influence” and in P. Howard–J. E. Rubin “Consequences of the Axiom of Choice”. We also prove that ACWO ↛ NDS in ZF and that “for all infinite cardinals m, m + m = m” ↛ NDS in ZFA. (shrink)

This is a continuation of [2]. We study the Tychonoff Compactness Theorem for various definitions of compactness and for various types of spaces . We also study well ordered Tychonoff products and the effect that the multiple choice axiom has on such products.

We study statements about countable and well-ordered unions and their relation to each other and to countable and well-ordered forms of the axiom of choice. Using WO as an abbreviation for “well-orderable”, here are two typical results: The assertion that every WO family of countable sets has a WO union does not imply that every countable family of WO sets has a WO union; the axiom of choice for WO families of WO sets does not imply that the countable union (...) of countable sets is WO. (shrink)

We study the relationships between definitions of compactness in topological spaces and the roll the axiom of choice plays in these relationships.

We study conditions for a topological space to be metrizable, properties of metrizable spaces, and the role the axiom of choice plays in these matters.

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

In lieu of an abstract, here is a brief excerpt of the content:American Journal of Philology 124.2 (2003) 306-309 [Access article in PDF] Philippe Rouet. Approaches to the Study of Attic Vases: Beazley and Pottier. Trans. Liz Nash. Oxford Monographs on Classical Archaeology. Oxford: Oxford University Press, 2001. xiii + 167 pp. 21 black and white plates. Cloth, $74. This monograph examines the development of two major approaches in the study of Greek vase painting by focusing on a comparison of (...) the work of Sir John D. Beazley with that of Edmond Pottier. Beazley, an English scholar, spent his scholarly life attributing vases to various formerly unnamed artists based on [End Page 306] their style of drawing, thereby ascertaining for the first time the artistic history and stylistic development of Attic black-figure and red-figure vase painting. Pottier, a French scholar, founded the Corpus Vasorum Antiquorum, an international series whose original goal was to publish all ancient clay vases. Each scholar's interests contrasted with the other's in many ways. Beazley's work focused more on the object and Athens, while Pottier was opposed to the study of individual artists and was particularly interested in the relationship of the origins of Greek civilization to the East and the broader context of the vessels.The book's introduction sets the historical and intellectual background of Beazley and Pottier. Areas covered include the early history of collecting, initial attempts at defining the works of individual Greek vase painters, some influential early catalogues of Greek vases (e.g., those of Hamilton's collection), and the role that the copying of motifs from ancient pottery had in spreading the interest in Greek vase painting in the late eighteenth and early nineteenth centuries, particularly the part played by the Wedgwood workshop. I miss here any reference to the fine work of Brian A. Sparkes on these subjects (The Red and the Black: Studies in Greek Pottery[London and New York, 1996] 34-63).The first chapter considers the most influential, immediate predecessors of Beazley and shows how their work formed the intellectual framework for his accomplishment. They are Wilhelm Klein, whose important study of and signatures on Attic vases still serves as the basis for our interpretation of them; Paul Hartwig, who was the first to attribute vases to an anonymous master; and Adolph Furtwängler, who in collaboration with Karl Reichhold initiated the monumental three-volume work, Griechische Vasenmalerei, which featured exceptionally accurate drawings of vase paintings. The author astutely notes that Furtwängler's work on attributing Roman copies of Greek sculpture to artists was likewise influential in augmenting the interest in style and artistic personalities. The intertwined relationship between connoisseurship, collectors, and the art market is touched on briefly in the discussions of Hartwig and Edward Warren. It might also have been noted here that the wording and style of Beazley's earliest work on the Kleophrades Painter clearly owes its inspiration to Hartwig.Pottier's early life and career are the focus of the next chapter. This was the time when museum catalogues and encyclopedic dictionaries were for many the signs of significant national scholarship. Indeed, after France's loss in 1870 in the Franco-Prussian War, Pottier and many of his contemporary compatriots sought to affirm the intellectual vitality of their nation by initiating and completing such projects. Pottier's contribution was to publish Vases antiques du Louvre, in which photography was used for the first time on a large scale to illustrate the vases, and to serve as one of the editors of the Dictionnaire des antiquités grecques et romaines, in which he was also responsible for many of the entries on vases.Chapter 3 returns to the subject of connoisseurship and the two non-classical archaeologists whose methodology bear clear resemblances to Beazley's. The first of them, Giovanni Morelli, was the first to attempt a scientific methodology for attributing paintings to unknown artists by examining the minor details [End Page 307] of drawings in order to discover the artistic language of the painters. Rouet concludes that Morelli paved the way for Beazley's work, for... (shrink)

Although physicalism has been the dominant position in recent work in the philosophy of mind, this dominance has not prevented a small but growing number of philosophers from arguing that physicalism is untenable for several reasons: both ontologically and epistemologically it cannot reduce mentality to the realm of the physical, and its attempts to reduce subjectivity to objectivity have thoroughly failed. The contributors to After Physicalism provide powerful alternatives to the physicalist account of the human mind from a dualistic point (...) of view and argue that the reductive and naturalistic paradigm in philosophy has lost its force. The essays in this collection all firmly engage in a priori metaphysics. Those by Uwe Meixner, E. J. Lowe, John Foster, Alvin Plantinga, and Richard Swinburne are concerned with ways to establish the truth of dualism. Essays by William Hasker, A. D. Smith, and Howard Robinson deal with the relation between physicalism and dualism. Benedikt Paul Göcke argues that the “I” is not a particular and Stephen Priest that “I have to understand myself not as a thing but as no-thing-ness.” In the final essay, Thomas Schärtl argues that there are limits to dualism as indicated by the concept of resurrection. By including two classical essays by Plantinga and Swinburne, the volume conveniently brings together some of the best and the newest thinking in making the philosophical case for dualism. "Seven of these essays are by eminent philosophers: Lowe, Foster, Plantinga, Swinburne, Hasker, Smith, and Robinson, each recapitulating his well-known position in the debate. To have these seven essayists together under one cover constitutes a remarkable book, which can be used as a textbook in philosophy of mind as well as in philosophy of religion courses, and which also opens up the debate in an original way among colleagues at an advanced level." —Fergus Kerr, University of Edinburgh.

Though Frege was interested primarily in reducing mathematics to logic, he succeeded in reducing an important part of logic to mathematics by defining relations in terms of functions. By contrast, Whitehead & Russell reduced an important part of mathematics to logic by defining functions in terms of relations (using the definite description operator). We argue that there is a reason to prefer Whitehead & Russell's reduction of functions to relations over Frege's reduction of relations to functions. There is an interesting (...) system having a logic that can be properly characterized in relational but not in functional type theory. This shows that relational type theory is more general than functional type theory. The simplification offered by Church in his functional type theory is an over-simplification: one can't assimilate predication to functional application.<br>. (shrink)

The relationship between individuals’ creativity and their ethical ideologies appears to be complex. Applying Forsyth’s (1980, 1992) personal moral philosophy model which consists of two independent ethical ideology dimensions, idealism and relativism, we hypothesized and found support for a positive relationship between creativity and relativism. It appears that creative people are less likely than non-creative people to follow universal rules in their moral decision making. However, contrary to our hypothesis and the general stereotype that creative people are less caring about (...) others, we found a positive relationship between creativity and idealism. These findings indicate that highly creative people are likely to be what Forsyth called “situationists,” individuals with both an ethic of caring and a pragmatic moral decision-making style. The finding that creative individuals tend to be situationists, and particularly that they tend to be high in idealism, appears to refute the line of reasoning that argues for a “creative personality” characterized in part by social insensitivity. Understanding the relationship between creativity and ethical ideologies has important implications for researchers, managers and teachers. (shrink)

Zoos and aquariums have an enormous global reach and hence an ability to craft meaningful conservation action for threatened species, implement educational strategies to encourage human engagement, development and behavior change, and conduct scientific research to enhance the husbandry, roles and impacts of the living collection. The recreational role of the zoo is also vast- people enjoy visiting the zoo and this is often a shared experience amongst family and friends. Evaluating how the zoo influences this “captive audience” and extending (...) its reach to include a compassionate approach to animals and people can further enhance the mission, value, and relevance of their work. The modern zoo’s current aims—Conservation, Education, Research and Recreation—provide useful foundations for the activities that zoos conduct at a local and national level. However, to improve sustainability of their actions and outcomes, we feel that Wellbeing should become the fifth aim of the modern zoo for the future- both from an animal perspective and from a human perspective. This paper provides discussion and review of how Wellbeing is already a substantial part of what zoos work on as well as posing the idea of altering the Recreation aim of the zoo to one of Engagement, which potentially is more measurable and therefore can allow zoo researchers and managers further options for the collection of evidence on the local and global reach of their zoo’s aims. Education, Engagement, Conservation, Research and Wellbeing provide a more complete picture of the roles of the modern zoo for the animals, human visitors and workforce, and to society more widely.

At the beginning of the 1950s most students of animal behavior in Britain saw the instinct concept developed by Konrad Lorenz in the 1930s as the central theoretical construct of the new ethology. In the mid 1950s J.B.S. Haldane made substantial efforts to undermine Lorenz''s status as the founder of the new discipline, challenging his priority on key ethological concepts. Haldane was also critical of Lorenz''s sharp distinction between instinctive and learnt behavior. This was inconsistent with Haldane''s account of the (...) evolution of language, and, according to Haldane, inconsistent with elementary genetics. British attitudes to the instinct concept changed dramatically in the wake of Daniel S. Lehraman''s 1953 critique of Lorenz, and by the 1960s Lorenz drew a clear distinction between his own views and those of the English-speaking ethologists. The inconsistencies between Lorenz''s ideas and the trends in contemporary evolutionary genetics that are reflected in Haldane''s critiques may help to explain why the Lorenzian instinct concept was unable to maintain itself in Britian.

The aim of appraisal theory in the psychology of emotion is to identify the features of the emotion-eliciting situation that lead to the production of one emotion rather than another². A model of emotional appraisal takes the form of a set of dimensions against which potentially emotion-eliciting situations are assessed. The dimensions of the emotion hyperspace might include, for example, whether the eliciting situation fulfills or frustrates the subject’s goals or whether an actor in the eliciting situation has violated a (...) norm. Richard Lazarus’s well-known model of emotional appraisal has six dimensions, and the regions of the resulting hyperspace that correspond to particular emotions are summarized by Lazarus as the ‘core relational themes’ of those emotions. Anger, for examples, is elicited by the core relational theme ‘a demeaning offence against me and mine’, sadness by ‘having experienced an irrevocable loss’ and guilt by ‘having transgressed a moral imperative’ (Lazarus, 1991).

Donation after cardiac death (DCD) is associated with many problems, including ischemic injury, high rates of delayed allograft function, and frequent organ discard. Furthermore, many potential DCD donors fail to progress to asystole in a manner that would enable safe organ transplantation and no organs are recovered. DCD protocols are based upon the principle that the donor must be declared dead prior to organ recovery. A new protocol is proposed whereby after a donor family agrees to withdrawal of life-sustaining treatments, (...) premortem nephrectomy is performed in advance of end-of-life management. Since nephrectomy should not cause the donor's death, this approach satisfies the dead donor rule. The donor family's wishes are best met by organ donation, successful outcomes for the recipients, and a dignified death for the deceased. This proposal improves the likelihood of achieving these objectives. (shrink)
