Cindy Sheehan’s life was profoundly altered when her son, Casey, was killed in combat on April 4, 2004, in Sadr City, Baghdad. Within a short period of time, she transformed her private grief into a series of public protests against the war policies of President George W. Bush. From an open letter to Bush on the seven-month anniversary of Casey’s death that excoriated his “reckless and wanton foreign policies” to appearing as part of a political advertisement against (...) class='Hi'>Bush in the fall of 2004 to her prominent August 2005 vigil in Crawford, Texas, the site of Bush’s vacation ranch, Sheehan became a visible symbol and lightning rod for opposition to the Iraq War. Following her transition from aggrieved mother to antiwar protestor and peace advocate will be the focus of this chapter. (shrink)

Anterior cingulate cortex (ACC) is a part of the brain's limbic system. Classically, this region has been related to affect, on the basis of lesion studies in humans and in animals. In the late 1980s, neuroimaging research indicated that ACC was active in many studies of cognition. The findings from EEG studies of a focal area of negativity in scalp electrodes following an error response led to the idea that ACC might be the brain's error detection and correction device. In (...) this article, these various findings are reviewed in relation to the idea that ACC is a part of a circuit involved in a form of attention that serves to regulate both cognitive and emotional processing. Neuroimaging studies showing that separate areas of ACC are involved in cognition and emotion are discussed and related to results showing that the error negativity is influenced by affect and motivation. In addition, the development of the emotional and cognitive roles of ACC are discussed, and how the success of this regulation in controlling responses might be correlated with cingulate size. Finally, some theories are considered about how the different subdivisions of ACC might interact with other cortical structures as a part of the circuits involved in the regulation of mental and emotional activity.

The usual treatment of a dinner table utterance of ‘Can you pass the salt?’ is that it involves an indirect request to pass the salt as well as a direct question about the hearer’s ability to do so: an indirect speech act. These are held to involve two illocutionary forces and two illocutionary acts. Rod Bertolet has raised doubts about whether consideration of such examples warrants the postulation of indirect speech acts and illocutionary forces other than the literal ones. In (...) a recent article, Mary Kate McGowan, Shan Shan Tam, and Margaret Hall claim to show that these doubts are unfounded. The purpose of this paper is to show that they have not established this.

Traces the development of recursive functions from their origins in the late nineteenth century to the mid-1930s, with particular emphasis on the work and influence of Kurt Gödel.

We report on some recent work centered on attempts to understand when one set is more random than another. We look at various methods of calibration by initial segment complexity, such as those introduced by Solovay [125], Downey, Hirschfeldt, and Nies [39], Downey, Hirschfeldt, and LaForte [36], and Downey [31]; as well as other methods such as lowness notions of Kučera and Terwijn [71], Terwijn and Zambella [133], Nies [101, 100], and Downey, Griffiths, and Reid [34]; higher level randomness notions (...) going back to the work of Kurtz [73], Kautz [61], and Solovay [125]; and other calibrations of randomness based on definitions along the lines of Schnorr [117].These notions have complex interrelationships, and connections to classical notions from computability theory such as relative computability and enumerability. Computability figures in obvious ways in definitions of effective randomness, but there are also applications of notions related to randomness in computability theory. For instance, an exciting by-product of the program we describe is a more-or-less naturalrequirement-freesolution to Post's Problem, much along the lines of the Dekker deficiency set. (shrink)

The first book in English on Gadamer's relationship to Heidegger, this study illustrates the philosophical power Gadamer's thinking has achieved by departing from Heidegger's at certain crucial moments.

Recent research on the metaethical beliefs of ordinary people appears to show that they are metaethical pluralists that adopt different metaethical standards for different moral judgments. Yet the methods used to evaluate folk metaethical belief rely on the assumption that participants interpret what they are asked in metaethical terms. We argue that most participants do not interpret questions designed to elicit metaethical beliefs in metaethical terms, or at least not in the way researchers intend. As a result, existing methods are (...) not reliable measures of metaethical belief. We end by discussing the implications of our account for the philosophical and practical implications of research on the psychology of metaethics. (shrink)

The classic case for why government must support science—with a new essay by physicist and former congressman Rush Holt on what democracy needs from science today Science, the Endless Frontier is recognized as the landmark argument for the essential role of science in society and government’s responsibility to support scientific endeavors. First issued when Vannevar Bush was the director of the US Office of Scientific Research and Development during the Second World War, this classic remains vital in making the (...) case that scientific progress is necessary to a nation’s health, security, and prosperity. Bush’s vision set the course for US science policy for more than half a century, building the world’s most productive scientific enterprise. Today, amid a changing funding landscape and challenges to science’s very credibility, Science, the Endless Frontier resonates as a powerful reminder that scientific progress and public well-being alike depend on the successful symbiosis between science and government. This timely new edition presents this iconic text alongside a new companion essay from scientist and former congressman Rush Holt, who offers a brief introduction and consideration of what society needs most from science now. Reflecting on the report’s legacy and relevance along with its limitations, Holt contends that the public’s ability to cope with today’s issues—such as public health, the changing climate and environment, and challenging technologies in modern society—requires a more capacious understanding of what science can contribute. Holt considers how scientists should think of their obligation to society and what the public should demand from science, and he calls for a renewed understanding of science’s value for democracy and society at large. A touchstone for concerned citizens, scientists, and policymakers, Science, the Endless Frontier endures as a passionate articulation of the power and potential of science. (shrink)

As a natural example of a 1-random real, Chaitin proposed the halting probability Ω of a universal prefix-free machine. We can relativize this example by considering a universal prefix-free oracle machine U. Let [Formula: see text] be the halting probability of UA; this gives a natural uniform way of producing an A-random real for every A ∈ 2ω. It is this operator which is our primary object of study. We can draw an analogy between the jump operator from computability theory (...) and this Omega operator. But unlike the jump, which is invariant under the choice of an effective enumeration of the partial computable functions, [Formula: see text] can be vastly different for different choices of U. Even for a fixed U, there are oracles A =* B such that [Formula: see text] and [Formula: see text] are 1-random relative to each other. We prove this and many other interesting properties of Omega operators. We investigate these operators from the perspective of analysis, computability theory, and of course, algorithmic randomness.

William James argued for a philosophy of democracy and pluralism that advocates individual and collective responsibility for our social arrangements, our morality, and our religion. In James' view, democracy resides first and foremost not in governmental institutions or in procedures such as voting, but rather in the characteristics of individuals, and in qualities of mind and conduct. It is a philosophy for social change, counselling action and hope despite the manifold challenges facing democratic politics, and these issues still resonate strongly (...) today. In this book, Stephen Bush explores how these themes connect to James' philosophy of religion, his moral thought, his epistemology, his psychology, and his metaphysics. His fresh and original study highlights the relevance of James' thought to modern debates, and will appeal to scholars and students of moral and political philosophy. (shrink)

A splitting of an r.e. set A is a pair A1, A2 of disjoint r.e. sets such that A1 A2 = A. Theorems about splittings have played an important role in recursion theory. One of the main reasons for this is that a splitting of A is a decomposition of A in both the lattice,, of recursively enumerable sets and in the uppersemilattice, R, of recursively enumerable degrees. Thus splitting theor ems have been used to obtain results about the structure (...) of, the structure of R, and the relationship between the two structures. Furthermore it is fair to say that questions about splittings have often generated important new technical developments in recursion theory. In this article we survey most of the results and techniques associated with splitting properties of r.e. sets in ordinary recursion theory. (shrink)

We describe punctual categoricity in several natural classes, including binary relational structures and mono-unary functional structures. We prove that every punctually categorical structure in a finite unary language is${\text {PA}}(0')$-categorical, and we show that this upper bound is tight. We also construct an example of a punctually categorical structure whose degree of categoricity is$0''$. We also prove that, with a bit of work, the latter result can be pushed beyond$\Delta ^1_1$, thus showing that punctually categorical structures can possess arbitrarily complex (...) automorphism orbits.As a consequence, it follows that binary relational structures and unary structures are not universal with respect to primitive recursive interpretations; equivalently, in these classes every rich enough interpretation technique must necessarily involve unbounded existential quantification or infinite disjunction. In contrast, it is well-known that both classes are universal for Turing computability. (shrink)

We examine the randomness and triviality of reals using notions arising from martingales and prefix-free machines.

We construct the set of the title, answering a question of Cholak, Jockusch, and Slaman [1], and discuss its connections with the study of the proof-theoretic strength and effective content of versions of Ramsey's Theorem. In particular, our result implies that every ω-model of RCA 0 + SRT 2 2 must contain a nonlow set.

Most research in experimental metaethics suggests high levels of interpersonal and intrapersonal variation in support for moral realism and antirealism among nonphilosophers (i.e., people without significant training in philosophy). These findings challenge the assumption that nonphilosophers share a uniform commitment to moral realism. Recent evidence challenges the validity of these studies by demonstrating that many people do not interpret questions about metaethics as intended. Pölzler and Wright offer a potential solution: train participants to understand the relevant metaethical distinctions. They devised (...) a set of paradigms that feature training exercises, comprehensive instructions, and detailed response options designed to mitigate unintended interpretations. I argue that their efforts were inadequate, and that the training required to ensure participants interpret stimuli as intended would need to be so extensive that it would effectively transform participants into novice philosophers. This leads to a dilemma: if training is unable to ensure adequate rates of intended interpretation, then it can’t resolve the threat to validity it was designed to address, while if it succeeds, participants will no longer represent nonphilosophers, which undermines the study’s external validity. Since research on other philosophical topics may likewise suffer from low rates of intended interpretations, e.g., free will and consciousness, this dilemma may have broader implications for experimental philosophy and psychology.

This textbook places emphasis on showing how useful a tool modal logic can be for formal philosophy, metaphysics, temporal reasoning, epistemics, the analysis of action and processes and ethical reasoning. Moving beyond propositional logic and predicate logic, modal logic gives the power to articulates and explore with precision philosophical arguments concerning possibility and necessity that are essential concepts in thought. This textbook is intended as an introductory study of modal logics with philosophy. In part 1 the reader is introduced to (...) some standard systems of modal logic, emphasis being on world semantics for modal logics. Part 2 explores modal logic applications to profound philosophical issues. (shrink)

We prove that there exists a noncomputable c.e. real which is low for weak 2-randomness, a definition of randomness due to Kurtz, and that all reals which are low for weak 2-randomness are low for Martin-Löf randomness.

Three understandings of the nature of religion--religion as experience, symbolic meaning, and power--have dominated scholarly discussions, in succession, for the past hundred years. Proponents of each of these three approaches have tended to downplay, ignore, or actively criticize the others. But why should the three approaches be at odds? Religion as it is practiced involves experiences, meanings, and power, so students of religion should attend to all three. Furthermore, theorists of religion should have an account that carefully conceptualizes all three (...) aspects, without regarding any of them as more basic than the others.Visions of Religion provides just such an account. Stephen S. Bush examines influential proponents of the three visions, arguing that each approach offers substantial and lasting contributions to the study of religion, although each requires revision.Bush rehabilitates the concepts of experience and meaning, two categories that are much maligned these days. In doing so, he shows the extent to which these categories are implicated in matters of social power. As for power, the book argues that the analysis of power requires attention to meaning and experience.Visions of Religion accomplishes all this by articulating a social practical theory of religion that can account for all three aspects, even as it incorporates them into a single theoretical framework.

In their book, Darwinism Evolving: Systems Dynamics and the Genealogy of Natural Selection, Depew and Weber argued for the need to address the relationship between self-organization and natural selection in evolutionary theory, and focused on seven “visions” for doing so. Recently, Batten et al. in a paper in this journal, entitled “Visions of evolution: self-organization proposes what natural selection disposes,” picked up the issue with the work of Depew and Weber as a starting point. While the efforts of both sets (...) of authors are to be commended, there are substantive errors in both the presentations of my work and of my work with colleagues that undermine theirs. My purpose here is to correct the errors in question, thereby removing the undermining effects and in so doing reassert the position my colleagues and I first advanced more than two decades ago, and that I still stand by and argue for today. The central points are as follows: Self-organization or spontaneous ordering is a process of selection; this selection process is governed by a “physical selection principle”; this principle is the law of maximum entropy production; and natural selection is a special case where the components are replicating.

We characterize the class of c.e. degrees that bound a critical triple as those degrees that compute a function that has no ω-c.e. approximation.

Salespeople have long been considered unique employees. They tend to work apart from each other and experience little daily contact with supervisors and other organizational employees. Additionally, salespeople interact with customers in an increasingly complex and multifunctional environment. This provides numerous opportunities for unethical behavior which has been chronicled in the popular press as well as academic research. Much of the research in sales ethics has relied on conceptual foundations which focus on individual and organizational influencers on ethical decision making. (...) While significant, contributors to this research suggest that alternative theoretical perspectives and methods of investigation should be utilized and call for more research on the status of professional selling as a whole. We answer this call by exploring an alternative and complementary perspective based on the theory of occupational choice, social learning, and work groups to gain insight on how the sales profession evolves as its own subculture that extends beyond individual and organizational boundaries. First, we discuss the characteristics of the sales profession and empirically examine the relationship between typical individual and organizational factors and sales professionals’ perceptions of ethical behavior. Second, we offer a theoretical explanation that our findings may be due to how salespeople choose and are socialized into the subculture of the sales profession. Third, we examine this theoretical perspective via qualitative in-depth interviews with experienced sales professionals. Results and implications are discussed in terms of a sales profession code of ethics and future research directions. (shrink)

In Plato on the Unity of the Virtues, Rod Jenks argues that while Plato makes several attempts to show how virtue is one, he deliberately fails to secure this because he thinks the way in which the virtues are both one and many is finally ineffable.

A deed is a governmental conveyance, a power asserted by the written, for, as William Carlos Williams wrote to Robert Creeley: “the government can never be more than the government of the words.” The question of ownership, of the words with which we define ourselves and each other, and of whose and what claims are legitimate is much at issue in Rod Smith’s _Deed,_ a lyric, ambitious, rebellious work thoroughly grounded in the New American tradition of poets such as John (...) Ashbery, Allen Ginsberg, and Charles Olson. (shrink)

This book asks what it means to be Muslim, yet not pious, in Iraqi Kurdistan. Though Islam is often represented in terms of either daily devotion, such as prayer and fasting, or abandonment of faith, there are many who turn away from tradition without departing from Islam. J. Andrew Bush offers us a new way to understand religious difference in Islam, one that invites questions about divine texts and rejects easy answers about political or sectarian identities. Exploring the lives (...) of irreligious Muslims, Bush highlights the paradoxes of their ethical orientation. While profoundly averse to many aspects of Islamic traditions, irreligious Muslims nonetheless harbor attractions to other aspects--such as Sufi poetry. Exploring this complex weave of attraction and aversion, Relating to Islam in Kurdistan provides intimate portraits of irreligious Kurdish Muslims in everyday life and the historical conditions that have allowed such paradoxical religious orientations to appear very ordinary in contemporary Kurdistan. Whether readers approach the book as Muslims with a commitment to Islam, or as Muslims with ambivalence to Islam, or as non-Muslims who bear their own forms of certainty or ambivalence about Islam, the book will open to the door to thinking about the relationship between commitment and ambivalence in Islamic traditions.

We introduce a new hierarchy of computably enumerable degrees. This hierarchy is based on computable ordinal notations measuring complexity of approximation of${\rm{\Delta }}_2^0$functions. The hierarchy unifies and classifies the combinatorics of a number of diverse constructions in computability theory. It does so along the lines of the high degrees (Martin) and the array noncomputable degrees (Downey, Jockusch, and Stob). The hierarchy also gives a number of natural definability results in the c.e. degrees, including a definable antichain.

We describe the manner in which the physical picture emerging from hydrodynamic quantum analogs (HQAs) may serve to resolve some of the longstanding difficulties of quantum mechanics. We enumerate some of the most significant intellectual cul-de-sacs of quantum mechanics, and the manner in which HQA suggests a route past them. Particular attention is given to enumerating the many guises of quantum nonlocality as it appears in the standard quantum interpretations. We illustrate how one might misinfer such nonlocality from the walking-droplet (...) system if one had an incomplete description of the system dynamics, if the variables required for its complete description were hidden rather than in plain sight. We highlight recent work that illustrates how phenomena typically attributed to nonlocality in quantum systems may be rationalized in terms of classical, pilot-wave dynamics. Finally, we define the frontiers of the field of hydrodynamic quantum analogs, including attempts to achieve classical entanglement by demonstrating Bell violations in pilot-wave hydrodynamics, and attempts to develop a model of quantum dynamics informed by the walking-droplet system.

A splitting A1A2 = A of an r.e. set A is called a Friedberg splitting if for any r.e. set W with W — A not r.e., W — Ai≠0 for I = 1,2. In an earlier paper, the authors investigated Friedberg splittings of maximal sets and showed that they formed an orbit with very interesting degree-theoretical properties. In the present paper we continue our investigations, this time analyzing Friedberg splittings and in particular their orbits and degrees for various classes (...) of r.e. sets. (shrink)

We give a proof of a theorem of Harrington that there is no orbit of the lattice of recursively enumerable sets containing elements of each nonzero recursively enumerable degree. We also establish some degree theoretical extensions.

presents a puzzle as to whether Aristotle views morally virtuous activity as happiness, as book 1 seems to indicate, or philosophical contemplation as happiness, as book 10 seems to indicate. The most influential attempts to resolve this issue have been either monistic or inclusivist. According to the monists, happiness consists exclusively of contemplation. According to the inclusivists, contemplation is one constituent of happiness, but morally virtuous activity is another. In this essay I will examine influential defenses of monism. Finding these (...) accounts superior to inclusivism, but still deficient, I will present and defend a dualistic account of happiness in which two different types of happiness, one divine and one human, are present in Nicomachean Ethics. When Aristotle commends contemplation as a happiness that humans can attain, he is careful to specify that this activity corresponds to a capacity (nous) that is not, properly speaking, human, even though humans can exercise it. Contemplation, the divine good, is the highest good that humans can obtain, but it is not the characteristic human good. The characteristic human good corresponds to the specifically and merely human function, which is an activity of the compound of human reason and emotions. (shrink)

The “hard problem” of the origin and nature of intelligence (cognition/“mind”) in the cosmos and its relation to symmetry and symmetry breaking goes back to the pre-Socratic Parmenides who claimed true reality (ontology) was a state of perfect symmetry and the world of change we know an illusion. Parmenides’s problem was that his ideal symmetry was broken ab initio by the cognitive act of him asserting it. This incommensurable separation of the time-asymmetric cognitive part of the world and physics came (...) into modern science with Cartesian dualism and the time-symmetric equations of Newton and then with the measurement problem in quantum mechanics. The aporia is also found in the belief that unifying the forces of nature under a single symmetry would provide a “theory of everything” (TOE). Cosmology shows, however, it is symmetry breaking rather than symmetry that has brought the universe into being. Irreducible to the time-reversal symmetry of classical and quantum mechanics, an expanded thermodynamics, specifically the addition of the fourth law of thermodynamics, provides a universal explanation. Coupled with a first law time-translation symmetry account of information (in the meaningful sense) the origin, nature and evolution of cognition is readily seen as a direct manifestation of universal law rather than somehow sitting impossibly outside it.
