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

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)

Leader-managers face a myriad of competing values when they engage in ethical decision-making. Few studies help us understand why certain reasons for action are justified, taking precedence over others when people choose to respond to an ethical dilemma. To help address this matter we began with a qualitative approach to disclose leader-managers' moral motives when they decide to address a work-related ethical dilemma. One hundred and nine military officers were asked to provide their reasons for taking action, justifications of their (...) reasons, and to explain these justifications. We used network analysis techniques to identify a hierarchical motive structure. The motive structure is a cognitive map that identifies ethical motives and perceptions of how these ethical motives relate to each other. The motives identified represent classic conceptualizations of moral behavior; namely, virtue theories, consequentialism, and deontological theories, along with another category that expressed the emotional significance of the moral judgment, which we refer to as emotional empiricism.

Can ethical character be stimulated and enabled? Cognitive understanding of organizational ethics issues is important and necessary, but not sufficient. Ethical behavior does not emerge automatically. Effective political method is necessary. While it may be difficult to teach ethical character, nonetheless, skill development with respect to joined ethics understanding and action-learning methods can help us develop the skills and confidence we need to actualize our ethical characters and social concerns. An action-learning approach to organizational ethics can help stimulate and enable (...) ethical character. (shrink)

We consider approaches to explanation within the cognitive sciences that begin with Marr's computational level or Marr's implementational level and argue that each is subject to fundamental limitations which impair their ability to provide adequate explanations of cognitive phenomena. For this reason, it is argued, explanation cannot proceed at either level without tight coupling to the algorithmic and representation level. Even at this level, however, we argue that additional constraints relating to the decomposition of the cognitive system into a set (...) of interacting subfunctions are required. Integrated cognitive architectures that permit abstract specification of the functions of components and that make contact with the neural level provide a powerful bridge for linking the algorithmic and representational level to both the computational level and the implementational level.

The problem this article focuses on is not the isolated individual act of corruption, but the systematic, pervasive sub-system of corruption that can and has existed across historical periods, geographic areas, and political-economic systems. It is important to first understand how corrupt and unethical subsystems operate, particularly their network nature, in order to reform and change them while not becoming what we are trying to change. Twelve key system elements are considered that include case examples from Asia, Latin America, the (...) Mediterranean, and North America. A key operating feature of corruption sub-systems is that they are relatively stable networks rather than exceptional, independent, individual events. Drawing on social network, social movement, and action-learning theories, six theory building propositions concerning ethical corruption reform are developed. (shrink)

Philosophical discussions of health and disease have traditionally been dominated by a debate between normativists, who hold that health is an inescapably value-laded concept and naturalists, such as Christopher Boorse, who believe that it is possible to derive a purely descriptive or theoretical definition of health based upon biological function. In this paper I defend a distinctive view which traces its origins in Aristotle's naturalistic ethics. An Arisotelian would agree with Boorse that health and disease are ubiquitous features of the (...) natural world and thus not mere projections of human interests and values. She would differ from him in rejecting the idea that value is a non-natural quality. I conclude my discussion with some comments of the normative character of living systems. (shrink)

Surveys over the last twenty years have seen an ever-growing number of Americans disclaim religious affiliations and instead check the "none" box. In the first sociological exploration of organized secularism in America, Richard Cimino and Christopher Smith show how one segment of these "nones" have created a new, cohesive atheist identity through activism and the creation of communities. According to Cimino and Smith, the new upsurge of atheists is a reaction to the revival of religious fervor in American politics (...) since 1980. Feeling overlooked and underrepresented in the public sphere, atheists have employed a wide variety of strategies-some evangelical, some based on identity politics-to defend and assert themselves against their ideological opponents. These strategies include building and maintaining communities, despite the absence of the kinds of shared rituals, texts, and laws that help to sustain organized religions.Drawing on in-depth interviews with self-identified atheist, secularist, and humanist leaders and activists, as well as extensive observations and analysis of secular gatherings and media, Cimino and Smith illustrate how atheists organize and align themselves toward common goals, and how media-particularly web-based media-have proven invaluable in connecting atheists to one another and in creating a powerful virtual community. Cimino and Smith suggest that secularists rely not only on the Internet for community-building, but on their own new forms of ritual.This groundbreaking study will be essential reading for anyone seeking to understand the growing atheist movement in America.

Núñez et al. (2019) argue that cognitive science has failed either “to transition to a mature inter‐disciplinary coherent field” (p. 782) or “to generate a successful [Lakatosian] research program” (p. 789). We argue that the former was never the intention of many early researchers within the field, while the latter is an inappropriate criterion by which to judge an entire discipline. However, we concur with Núñez et al. (2019) that the individual disciplinary balance within cognitive science has changed over time. (...) Of particular concern is the fact that the use of computational methods appears to be on the wane. (shrink)

A key component of research on human sentence processing is to characterize the processing difficulty associated with the comprehension of words in context. Models that explain and predict this difficulty can be broadly divided into two kinds, expectation‐based and memory‐based. In this work, we present a new model of incremental sentence processing difficulty that unifies and extends key features of both kinds of models. Our model, lossy‐context surprisal, holds that the processing difficulty at a word in context is proportional to (...) the surprisal of the word given a lossy memory representation of the context—that is, a memory representation that does not contain complete information about previous words. We show that this model provides an intuitive explanation for an outstanding puzzle involving interactions of memory and expectations: language‐dependent structural forgetting, where the effects of memory on sentence processing appear to be moderated by language statistics. Furthermore, we demonstrate that dependency locality effects, a signature prediction of memory‐based theories, can be derived from lossy‐context surprisal as a special case of a novel, more general principle called information locality.

On the basis of the Weber, Jaspers, and Arendt style ‘ideal types’ of the manager as Eichmann, Richard III, and Faust it is explained how under strong organizational pressures to obey orders and further organizational ends, different types of managers cooperate with organization behavior that harms people.

Sex chromosomes can differ between species as a result of evolutionary turnover, a process that can be driven by evolution of the sex determination pathway. Canonical models of sex chromosome turnover hypothesize that a new master sex determining gene causes an autosome to become a sex chromosome or an XY chromosome pair to switch to a ZW pair (or vice versa). Here, a novel paradigm for the evolution of sex determination and sex chromosomes is presented, in which there is an (...) evolutionary transition in the master sex determiner, but the X chromosome remains unchanged. There are three documented examples of the novel paradigm, and it is hypothesized that a similar process could happen in a ZW sex chromosome system. Three other taxa are also identified where the novel paradigm may have occurred, and how it could be distinguished from canonical trajectories in these and additional taxa is also described.

Automatic imitation or “imitative compatibility” is thought to be mediated by the mirror neuron system and to be a laboratory model of the motor mimicry that occurs spontaneously in naturalistic social interaction. Imitative compatibility and spatial compatibility effects are known to depend on different stimulus dimensions—body movement topography and relative spatial position. However, it is not yet clear whether these two types of stimulus–response compatibility effect are mediated by the same or different cognitive processes. We present an interactive activation model (...) of imitative and spatial compatibility, based on a dual-route architecture, which substantiates the view they are mediated by processes of the same kind. The model, which is in many ways a standard application of the interactive activation approach, simulates all key results of a recent study by Catmur and Heyes (2011). Specifically, it captures the difference in the relative size of imitative and spatial compatibility effects; the lack of interaction when the imperative and irrelevant stimuli are presented simultaneously; the relative speed of responses in a quintile analysis when the imperative and irrelevant stimuli are presented simultaneously; and the different time courses of the compatibility effects when the imperative and irrelevant stimuli are presented asynchronously.

Action research is combined research and practical action where the researcher joins with and acts with practitioners to help improve practice and theory building. Action research can be a form of Aristotelian critical, ethical praxis that developmentally changes the action researcher and the external world. Bernstein’s and Eikeland’s interpretations of Aristotelian ethics praxis are considered. The Argyris et al. “action-science” and the van de Ven “engaged scholarship” forms of action research with their differently nuanced interpretations of Aristotelian philosophy as foundations (...) for action research are considered and compared as examples of action research as an ethics praxis method with respect to a key similarity with respect to joining of critical ethics and actionable knowledge; another key similarity with respect to action research practice that can developmentally change the action researcher and the external world; and a key difference with respect to academic literature versus practitioner-based theory building is also considered. Examples in the cases of the political economist and action researcher, Hirschmann’s “Exit,Voice, Loyalty” approach and Greenleaf’s “Servant Leadership” approach to action research as forms of Aristotelian critical, ethical praxis are analyzed.

What can and should we do as managers and administrators when our sense of personal morality is at odds with our organization's behavior? Among the many alternatives are: (1) not think about it; (2) go along and get along; (3) protest; (4) conscientiously object; (5) leave; (6) secretly blow the whistle; (7) publicly blow the whistle; (8) secretly threaten to blow the whistle; (9) sabotage; and, (10) negotiate and build consensus for a change in the unethical behavior. This article considers (...) the advantages and disadvantages of these ten types of strategies based on some philosophy, game theory and everyday pragmatics. (shrink)

ABSTRACT:In this updated and revised version of his 2008 Society for Business Ethics presidential address, Richard Nielsen documents the characteristics and extent of the 2007–2009 economic crisis and analyzes how the ethics issues of the economic crisis are structurally related to a relatively new form of capitalism, high-leverage finance capitalism. Four types of high-leverage finance capitalism are considered: hedge funds; private equity-leveraged buyouts; high-leverage, subprime mortgage banking; and high-leverage banking. The structurally related problems with the four types of high-leverage (...) finance capitalism converged in something of a perfect economic storm. Explanations for the crisis are offered in the context of the type of the high-leverage finance capitalism system that permitted and facilitated the economic crisis. Ethics issues and potential reforms are considered that may be able to mitigate the destructive effects of what Schumpeter referred to as the “creative destructive” effects of evolutionary forms of capitalism while realizing the Aristotelian economic ideal of creating wealth in such a way as to make us better people and the world a better place.

Slurs are words with a well-known tendency to conjure up painful memories and experiences in members of their target communities. Owing to this tendency, it’s widely agreed that one ought to exercise considerable care when even mentioning a slur, so as to avoid needlessly inflicting distressing associations on members of the relevant group. This paper argues that this tendency to evoke distressing associations is precisely what makes slurs impactful verbal weapons. According to the ballistic theory, slurs make such potent insults (...) because they enable their users to maliciously inflict noxious associations on members of their target groups. To motivate this theory, I demonstrate its ability to explain a number of facts about slurs’ offensiveness that pose formidable difficulties for competing theories of slurs. I argue that the ballistic theory not only explains why slurs make such explosively impactful terms of abuse, but also why: uses of slurs can provoke offense even when they aren’t interpreted as expressions of the speaker’s racist attitudes; and why mentions of slurs are inoffensive in some contexts, but in other contexts, warrant a level of offense every bit as severe as that warranted by weaponized uses. I conclude with a brief discussion of a practical application of the ballistic theory. I demonstrate that the theory has an important consequence for legislative efforts to regulate and punish weaponized uses of slurs. (shrink)

When is it legitimate for a government to ‘nudge’ its citizens, in the sense described by Thaler and Sunstein (2008)? In their original work on the topic, Thaler and Sunstein developed the _‘as judged by themselves’ (or AJBT) test_ to answer this question (Thaler and Sunstein 2008, p. 5). In a recent paper, Paul and Sunstein (2019) raised a concern about this test: it often seems to give the wrong answer in cases in which we are nudged to make a (...) decision that leads to what Paul calls a _personally transformative experience_, that is, one that results in our values changing (Paul 2014). In those cases, the nudgee will judge the nudge to be legitimate after it has taken place, but only because their values have changed as a result of the nudge. In this paper, I take up the challenge of finding an alternative test. I draw on my _aggregate utility account_ of how to choose in the face of what Ullmann-Margalit (2006) calls _big decisions_, that is, decisions that lead to these personally transformative experiences (Pettigrew 2019, Chapters 6 and 7).

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 26.2 (2002) 369-396 [Access article in PDF] Worlds or Words Apart?The Consequences of Pragmatism for Literary Studies:An Interview with Richard Rorty Richard Rorty, with E. P. Ragg ER: I WANTED TO ASK YOU first about holism. Clearly holism doesn't just mean being interdisciplinary. Nor, as you argue in Philosophy and the Mirror of Nature, is it merely a question of antifoundationalist polemic. Rather, you (...) say it marks "a distrust of the whole epistemological enterprise." 1 Could you explain what you mean by that?RR: If you weren't some kind of foundationalist you wouldn't bother to get into epistemology. Epistemology only looks attractive if you think that there is a topic called knowledge whose nature can be studied. The idea is that once you have learned its nature, you might get more of it than you had before. Only someone who thinks that knowledge has foundations located in sense perception, or pure reason, or divine revelation, or something, would take the idea of studying knowledge, its nature and limits, seriously. I think of holism as just the view that people change their beliefs in such a way as to achieve coherence with their other beliefs, to bring their beliefs and desires into some sort of equilibrium—and that that is about all there is to be said about the quest for knowledge. There are no rules for which beliefs you sacrifice in order to accommodate other beliefs, or which desires you change to accommodate changed beliefs. Because there aren't any rules, there aren't any methods you can study in order to improve the way you achieve equilibrium. The whole idea of studying how belief is changed is pretty hopeless. It's just too holistic a process to be an appropriate topic of study. [End Page 369]ER: Holism is obviously a natural corollary of pragmatism because pragmatists urge bringing as many different useful vocabularies to discussion as we can. This reminds me of your definition of "literariness." In Contingency, irony, and solidarity you describe literary skill as the ability to effect "surprising gestalt switches by making smooth rapid transitions from one terminology to another." 2 Would it be fair to say, then, that thinking holistically is, to some degree, literary?RR: No, I don't think so. It would be more appropriate to say thinking holistically, in the sense of not being limited to a given context or disciplinary framework, is a matter of thinking imaginatively. Politicians and theologians and engineers think imaginatively just as much as literary people do. To call it literary would be unduly to privilege literature.ER: Would you say that, as a writer, your own work has been treated holistically: first in the sense that your texts are seen as a growing body of thought—that is, that there is a difference between the writer of Philosophy and the Mirror of Nature and the author of Contingency, irony, and solidarity—and, second, in the sense that people have thought holistically about your ideas, have brought them to bear on literature, philosophy, social science, the very demarcations you want to transcend?RR: I think that the stuff I do is more interesting to people outside of philosophy than those inside it. This is an example of the same phenomenon that led Kuhn to be much more read by people outside the hard sciences than by people within them. My stuff, like Kuhn's, debunks certain views that various earlier philosophers, especially the positivists, had tried to impose on the culture. My readers are people who are looking for a way out from the view they absorbed, without much liking it, when they were young. People inside of philosophy, however, often regard all this debunking as endangering the problems to the solution of which they have devoted their lives. They do not want the problems dissolved, because that would dissolve their solutions as well. So they welcome it less than do outsiders.ER: One of the markers of your... (shrink)

This research explores the role of emotions in goal-directed behaviour. A model is provided for an emotional goal system whereby appraisals of the consequences of achieving or not achieving a goal are hypothesised to elicit anticipatory emotions; the anticipatory emotions are expected, in turn, to contribute to volitions in the service of goal pursuit (namely, intentions, plans, and the decision to expend energy); goal-directed behaviours next arise in response to volitions and lead to goal attainment; and the latter then functions (...) as the basis for a new set of appraisals and accompanying goaloutcome emotions. The model was tested in a longitudinal study of the responses of 406 adults (243 women, 163 men) in The Netherlands. The context for the study was the regulation of one's bodyweight via exercising and dieting. (shrink)

Crisis management can be simultaneously a content specific problem solving process and an opportunity for stimulating and enabling an organization's ethical tradition. Crisis can be an opportunity for ethical organizational development. Kierkegaardian "upbuilding" dialog method builds from within the internal ethical tradition of an organization to respond to crises while simultaneously adapting and protecting the organization's tradition. The crisis itself may not be a directly ethical crisis, but the method of responding to the crisis is built upon the ethical foundations (...) of an organization's tradition. A limitation of this method is that it may be less applicable to organizations with questionably ethical traditions. The concept of "upbuilding" dialog is derived from Kierkegaard, but here is applied to organizational crisis management. The method is illustrated and discussed in the context of a wrongful death crisis of the Dana- Farber Cancer Institute, a non-profit organization, and an economic survival crisis at Ben and Jerry's, a business organization.
