We introduce the notion T does not omit obstructions. If a stable theory does not admit obstructions then it does not have the finite cover property . For any theory T, form a new theory $T_{\rm Aut}$ by adding a new unary function symbol and axioms asserting it is an automorphism. The main result of the paper asserts the following: If T is a stable theory, T does not admit obstructions if and only if $T_{\rm Aut}$ has a model companion. (...) The proof involves some interesting new consequences of the nfcp. (shrink)

We use κ-free but not Whitehead Abelian groups to constructElementary Classes (AEC) which satisfy the amalgamation property but fail various conditions on the locality of Galois-types. We introduce the notion that an AEC admits intersections. We conclude that for AEC which admit intersections, the amalgamation property can have no positive effect on locality: there is a transformation of AEC's which preserves non-locality but takes any AEC which admits intersections to one with amalgamation. More specifically we have: Theorem 5.3. There is (...) an AEC with amalgamation which is not (N₀, N₁)-tame but is 2(N0, ∞)-tame; Theorem 3.3. It is consistent with ZFC that there is an AEC with amalgamation which is not (≤ N₂, ≤ N₂)-compact. (shrink)

We explore Shelah's model‐theoretic dividing line methodology. In particular, we discuss how problems in model theory motivated new techniques in model theory, for example classifying theories by their potential (consistently with Zermelo–Fraenkel set theory with the axiom of choice (ZFC)) spectrum of cardinals in which there is a universal model. Two other examples are the study (with Malliaris) of the Keisler order leading to a new ZFC result on cardinal invariants and attempts to clarify the “main gap” by reducing the (...) dependence of certain versions on (highly independent) cardinal arithmetic.

The existence of "undermining futures" appears to show that a contradiction can be deduced from the conjunction of Humean supervenience (HS) about chance and the Principal Principle. A number of strategies for rescuing HS from this problem have been proposed recently. In this paper, a novel way of defending HS from the threat is presented, and it is argued that this defense has advantages not shared by others. In particular, it requires no revisionism about chance, and it is equally available (...) to defenders of HS who hold HS to be necessary and those who hold it to be contingent. (shrink)

Thesis: The exclusion of organized labor/management issues from the principal arenas for business ethics study and discussions needs to be remedied. The paper develops this thesis in three steps: 1) Exclusion: A careful examination of select textbooks, journals, and conferences provides evidence as to the virtual absence of unions and such crucial organized labor/management issues as labor organizing and collective bargaining; 2) Inclusion: A series of brief arguments favoring inclusion of these issues in business ethics based on the notion of (...) privileged institutions, adversarial posturing, the societal benefits, and globalization; 3) Suggestions: Some practical, cooperative initiatives involving the academy, management and labor, such as, labor officials as guest speakers and members of business school committees, internships in labor organizations, training workshops in business ethics for labor leaders, fora for joint management/labor discussions of issues each group faces in the economy and the legislatures.

This paper contains portions of Baldwin’s talk at the Set Theory and Model Theory Conference and a detailed proof that in a suitable extension of ZFC, there is a complete sentence of \ that has maximal models in cardinals cofinal in the first measurable cardinal and, of course, never again.

This paper uses the resources of illocutionary logic to provide a new understanding of the Liar Paradox. In the system of illocutionary logic of the paper, denials are irreducible counterparts of assertions; denial does not in every case amount to the same as the assertion of the negation of the statement that is denied. Both a Liar statement, (a) Statement (a) is not true, and the statement which it negates can correctly be denied; neither can correctly be asserted. A Liar (...) statement, more precisely, an attempted Liar statement, fails to fulfill conditions essential to statements, but no linguistic rules are violated by the attempt. Ordinary language, our ordinary practice of using language, is not inconsistent or incoherent because of the Liar. We are committed to deny Liars, but not to accept or assert them. This understanding of the Liar Paradox and its sources cannot be fully accommodated in a conventional logical system, which fails to mark the distinction between sentences/statements and illocutionary acts of accepting, rejecting, and supposing statements.

In lieu of an abstract, here is a brief excerpt of the content:Aristotle On MetaphorJohn T. KirbyMuch Madness is divinest Sense—To a discerning Eye——Emily DickinsonOurs is an age of metaphor. Wayne Booth, in his inimitable fashion, remarks,There were no conferences on metaphor, ever, in any culture, until our own century was already middle–aged. As late as 1927, John Middleton Murry, complaining about the superficiality of most discussions of metaphor, could say, "There are not many of them."... Explicit discussions of (...) something called metaphor have multiplied astronomically in the past fifty years.... students of metaphor have positively pullulated.1In the postmodern era philosophers of language, particularly those outside the analytic tradition, tend to think more and more in terms of all language as being metaphorical. This trend, however, is not a new one; it seems to have its roots back as far as Heraclitus, and, in the modern world, was certainly espoused by Giambattista Vico in his Nuova Scienza (1725). What we may call the Viconian tradition was embraced on the continent by Nietzsche, and, in the Anglo–American world, by Ivor Richards.2 Nietzsche's thought had far–reaching consequences in terms of its influence on the work of Paul de Man and Jacques Derrida, who in the late 1960s and the 1970s found themselves in the center of a vortex of controversy over the notion of "deconstruction," and its interrogation not only of Western metaphysics but also of human language and thought generally. Now, it seemed, such simple formulae as "This X is Y" called into question the whole process of naming and predication. But even among those for whom this is an unconvincing position, the problem of metaphor continues to be a fascinating one. How to define [End Page 517] it? What are its uses? What is its relation to literal, or nonfigured, language? And what its relation to human cognition?3Booth goes on to say, "there have been many more discussions of what people from the Greek philosophers on called metaphor than any bibliography could show."4 That being so, a sustained study of Aristotle's concept of metaphor needs no further justification, since it is to him that we owe the terms in which the debate was framed for many hundreds of years. Indeed, here as often, even those who wish to propose new or different parameters for the analysis of metaphor must do so against the grain of the Aristotelian tradition.5 This, if nothing else, is a measure of the tremendous influence Aristotle has had on the history of Western rhetoric and poetics.As on many other topics, it is now fashionable to condescend to Aristotle for the limitations of his study of metaphor, or—more aggressively still—to find fault with its parameters. Certainly he did not preempt any further discussion on the issue; nor, I imagine, would he have wanted to. But I surmise that there is more to be learned from an appreciative study of his methods here than one might initially suppose. In this study, then, after a few remarks on recent studies of metaphor, I propose to examine the state of the question before Aristotle, and then [End Page 518] to look at what he has to say about metaphor in the Poetics and Rhetoric.In their attempts to cope with the notion of language generally, and specifically with the questions of literal versus figurative language, scholars over the last hundred years or so have themselves appropriated a number of metaphors purporting to describe the phenomenon. These include (above all) models based on comparison and interaction. The comparison model, it is typically said, conforms more to the classical approach to metaphor, whereas those based on interaction stem primarily from the work of Richards and Black.6 Indeed it is from this notion of interaction that the terms "tenor" and "vehicle" were born, the former referring to the underlying idea that is illustrated or illuminated by the latter, which is "applied" to it; and Richards is right both to point out [1] that the word "metaphor" is sometimes used to signify what he means by "vehicle," and sometimes to mean the symbiosis resulting from the conjunction of tenor and vehicle, and [2] that...

CHAPTER 1 Combinatorial Geometries and Infinitary Logics In this chapter we introduce two of the key concepts that are used throughout the text. ...

I argue that the standard way of formalizing the fine-tuning argument for design is flawed, and I present an alternative formalization. On the alternative formalization, the existence of life is not treated as the evidence that confirms design; instead it is treated as part of the background knowledge, while the fact that fine tuning is required for life serves as the evidence. I argue that the alternative better captures the informal line of thought that gives the fine-tuning argument its intuitive (...) plausibility, and I show that the alternative formalization avoids all of the most prominent objections to the fine-tuning argument, including the objection from observation selection effects, the problem of old evidence, the problem of non-normalizable probability measures and a further objection due to Monton. I conclude that the alternative formalization is the one that attention should be focused on. (shrink)

This paper seeks to dispel the notion that Mark Antony and the Senate indulged in a cat-and-mouse game over the control of Caesar's archives in the weeks immediately following the Ides of March. At stake was whether unpublished documents drawn up by Caesar before his death should be ratified and put into force. The belief that the Senate and Antony contended over this issue and that Antony got the upper hand rests primarily on what I hope to show is a (...) misinterpretation of two key passages in the Philippics. Moreover, since the standard interpretation of these two passages appears to be supported by Dio's account of how Antony cajoled the Senate into permitting him a freer hand to review and publish documents found in Caesar's archives, it will be necessary to have a closer look at Dio's probable sources for this particular section of his history.

The growth of esports as a recognized, organized, competitive activity in North America and Europe has evolved steadily from one of the most prominent sport industries in several Asian countries. Esports, which is still pursuing a widely accepted governance structure, has struggled to control the factors that typically act as a breeding ground for sport corruption. Within the esports industry, there is alleged widespread use of both prescription and off-label use of stimulants, such as modafinil, methylphenidate, and dextroamphetamine. Anti-doping policy (...) implementation in this environment may result in either the abuse of the Therapeutic Use Exemptions system or excluding too many competitors who have a legitimate need for these medications. In this paper, we contextualize esports and substance use within this emerging industry. Subsequently, we outline the specific challenges faced by esports organizations in crafting policies to address PEDs—one of the industry’s most pressing issues. Furt... (shrink)

This essay, which was originally presented at the first Coloquio Internacional at the Guadalajara Campus of the Universidad Panamericana, Mexico, October 8-10, is a short introduction to Newman’s writings in six areas—autobiography, philosophy, theology, literature, education and spirituality—along with some suggestions for additional reading, particularly for those beginning Newman studies.

Newman was a prolific writer, but one who usually wrote on “call”; sometimes these calls were unexpected, but at other times they were a pastoral responsibility. Such was the case with his sermons, which exhibit four characteristics: biblically based, theologically grounded, circumstantially relevant, and spiritually insightful. As such, his sermons still appeal to readers today.

This collection addresses the central issue of political philosophy or, in a couple of cases, issues very close to the heart of that question: Is government justified? This ancient question has never been more alive than at the present time, in the midst of continuing political and social upheaval in virtually every part of the world. Only two of the pieces collected here have been published previously. All the other contributions were, at the time of the inception of the volume, (...) fresh from the pens, or still to emerge from the pens, of their authors. (shrink)

On his famous walk to Vincennes to visit the imprisoned Diderot, Rousseau had what he called an “illumination”—the realization that man was naturally good but becomes corrupted by the influence of society—a fundamental change in Rousseau’s perspective that would animate all of his subsequent works. At that moment, Rousseau “saw” something he had hitherto not seen, and he made it his mission to help his readers share that vision through an array of rhetorical and literary techniques. In Rousseau’s Reader, (...) class='Hi'>John T. Scott looks at the different strategies Rousseau used to engage and persuade the readers of his major philosophical works, including the Social Contract, Discourse on Inequality, and Emile. Considering choice of genre; textual structure; frontispieces and illustrations; shifting authorial and narrative voice; addresses to readers that alternately invite and challenge; apostrophe, metaphor, and other literary devices; and, of course, paradox, Scott explores how the form of Rousseau’s writing relates to the content of his thought and vice versa. Through this skillful interplay of form and content, Rousseau engages in a profoundly transformative dialogue with his readers. While most political philosophers have focused, understandably, on Rousseau’s ideas, Scott shows convincingly that the way he conveyed them is also of vital importance, especially given Rousseau’s enduring interest in education. Giving readers the key to Rousseau’s style, Scott offers fresh and original insights into the relationship between the substance of his thought and his literary and rhetorical techniques, which enhance our understanding of Rousseau’s project and the audiences he intended to reach.

A law about frequencies would be a law of nature that imposes a constraint on one or more (actual, global) frequencies. On any of the leading philosophical approaches to laws of nature, there could be laws about frequencies. Hypotheses that posit laws about frequencies turn out to behave very similarly to hypotheses that posit corresponding laws about probabilities or chances -- they make the same predictions, provide similar explanations, and are confirmed or disconfirmed by empirical evidence in the same ways. (...) This makes it interesting to consider the possibility of interpreting probabilistic laws from scientific theories as laws about frequencies. This is surprising proposal, but I argue that the resulting view (which I call 'nomic frequentism') is able to overcome all of the standard objections to frequentist interpretation of objective probabilities.

Functionally, religion is what is held as sacred, that is, as untouchable. In the United States, taxes and military manpower are untouchable and, therefore, beyond objection by particular religions. The courts, too, are untouchable in determining what is and what is not religion. Despite these severe limitations on religious freedom, sometimes religion has broken the national consensus - most notably in the abolitionist movement of 1829-1865 and in the civil rights movement of 1959-1964. Such acts of religious freedom have been (...) the dynamism of profound social change. (shrink)

Subcreative sets, introduced by Blum, are known to coincide with the effectively speedable sets. Subcreative sets are shown to be the complete sets with respect to S-reducibility, a special case of Turing reducibility. Thus a set is effectively speedable exactly when it contains the solution to the halting problem in an easily decodable form. Several characterizations of subcreative sets are given, including the solution of an open problem of Blum, and are used to locate the subcreative sets with respect to (...) the complete sets of other reducibilities. It is shown that q-cylindrification is an order-preserving map from the r.e. T-degrees to the r.e. S-degrees. Consequently, T-complete sets are precisely the r.e. sets whose q-cylindrifications are S-complete. (shrink)

Since the mid‐1950s, the various research programs within cognitive science have advanced our basic understanding of human mental function. Over the past 20 years, this basic science of mind has also contributed to the genesis of an applied science of learning and teaching that can powerfully inform educational practice and dramatically improve educational outcomes. Classroom practice based on this applied science differs from traditional instruction in several ways. Instruction based on cognitive theory envisions learning as an active, strategic process. It (...) assumes that learning follows developmental trajectories within subject‐matter domains. It recognizes that learning is guided by the learners' introspective awareness and control of their mental processes. It emphasizes that learning is facilitated by social, collaborative settings that value self‐directed student dialogue. (shrink)

This paper will examine the circumstances that inspired the famous utterance attributed to the haruspex Spurinna, ‘Beware the Ides of March!'1Recently the argument has been made that this warning to Caesar was based upon an astrological calculation, rather than on the usual arts of an haruspex who read signs of the future by inspecting the entrails of sacrificial animals (exta) or by interpreting bolts of lightning (fulgura) and portents (ostenta). As intriguing as this astrological theory is, I am convinced that (...) it is fatally flawed, and I intend to show why it must ultimately be rejected. The question is not merely an academic one, having to do with the methods employed by a particular seer on a given occasion. Rather, if it can be established as even probable that Spurinna based his prophecy upon an astrological calculation, which helped convince the conspirators that Caesar was vulnerable to attack on the Ides as being an unlucky day for him according to the stars, then we are presented with a very significant and hitherto unsuspected instance of astrology influencing the course of public affairs at Rome several decades before astrology came into its own under the early emperors. According to such a reconstruction, astrology played a key role in determining the date of one of the most fateful murders in Roman history. It is the contention of this paper, on the contrary, that there is no reason whatsoever to attribute Spurinna's prophecy to an astrological calculation. (shrink)
