It is known that a number of inference principles can be used to trivialise the axioms of naïve comprehension - the axioms underlying the naïve theory of sets. In this paper we systematise and extend these known results, to provide a number of general classes of axioms responsible for trivialising naïve comprehension.

In his paper [6], Greg Restall conjectured that a logic supports a naïve comprehension scheme if and only if it is robustly contraction free, that is, if and only if no contracting connective is definable in terms of the primitive connectives of the logic. In this paper, we present infinitely many counterexamples to Restall''s conjecture, in the form of purely implicational logics which are robustly contraction free, but which trivialize naïve comprehension.

Curry's paradox, sometimes described as a general version of the better known Russell's paradox, has intrigued logicians for some time. This paper examines the paradox in a natural deduction setting and critically examines some proposed restrictions to the logic by Fitch and Prawitz. We then offer a tentative counterexample to a conjecture by Tennant proposing a criterion for what is to count as a genuine paradox.

In this paper we consider the implicational fragment of Abelian logic \ . We show that although the Abelian groups provide an semantics for the set of theorems of \ they do not for the associated consequence relation. We then show that the consequence relation is not algebraizable in the sense of Blok and Pigozzi . In the second part of the paper, we investigate an extension of \ in the same language and having the same set of theorems and (...) show that this new consequence relation is algebraizable with the Abelian groups as its equivalent algebraic semantics. Finally, we show that although \ is not algebraizable, it is order-algebraizable in the sense of Raftery. (shrink)

Abelian Logic is a paraconsistent logic discovered independently by Meyer and Slaney [10] and Casari [2]. This logic is also referred to as Abelian Group Logic (AGL) [12] since its set of theorems is sound and complete with respect to the class of Abelian groups. In this paper we investigate the pure implication fragment A→ of Abelian logic. This is an extension of the implication fragment of linear logic, BCI. A Hilbert style axiomatic system for A→ can obtained by adding (...) the axiom A (dubbed the ‘axiom of relativity’ by Meyer and Slaney) to BCI, as follows: B (α → β) → ((γ → α) → (γ → β)) C (α → (β → γ)) → ((β → (α → γ)) I α → α A ((α → β) → β) → α MP α, α → β ⇒ β.

In his paper, ìRight Weakening and Right Contraction in LK î, Hirokawa investigates the properties of the structural rules of contraction and weak- ening as they appear in a certain sequent calculus formulation of Örst order classical logic. In what follows we explore the notion of correspondence, in particular with reference to the structural rules in the succedent, and in doing so critically examine the sensitivity of Hirokawaís results to the formulation of the calculus, both with respect to the formulations (...) of the rules governing the connectives present and to the choice of the connectives themselves.

Only human beings have a rich conceptual repertoire with concepts like tort, entropy, Abelian group, mannerism, icon and deconstruction. How have humans constructed these concepts? And once they have been constructed by adults, how do children acquire them? While primarily focusing on the second question, in The Origin of Concepts , Susan Carey shows that the answers to both overlap substantially. Carey begins by characterizing the innate starting point for conceptual development, namely systems of core cognition. Representations of core (...) cognition are the output of dedicated input analyzers, as with perceptual representations, but these core representations differ from perceptual representations in having more abstract contents and richer functional roles. Carey argues that the key to understanding cognitive development lies in recognizing conceptual discontinuities in which new representational systems emerge that have more expressive power than core cognition and are also incommensurate with core cognition and other earlier representational systems. Finally, Carey fleshes out Quinian bootstrapping, a learning mechanism that has been repeatedly sketched in the literature on the history and philosophy of science. She demonstrates that Quinian bootstrapping is a major mechanism in the construction of new representational resources over the course of childrens cognitive development. Carey shows how developmental cognitive science resolves aspects of long-standing philosophical debates about the existence, nature, content, and format of innate knowledge. She also shows that understanding the processes of conceptual development in children illuminates the historical process by which concepts are constructed, and transforms the way we think about philosophical problems about the nature of concepts and the relations between language and thought.

A casual comment by a student alerted the authors to the existence and prevalence of Internet-based paraphrasing tools. A subsequent quick Google search highlighted the broad range and availability of online paraphrasing tools which offer free ‘services’ to paraphrase large sections of text ranging from sentences, paragraphs, whole articles, book chapters or previously written assignments. The ease of access to online paraphrasing tools provides the potential for students to submit work they have not directly written themselves, or in the case (...) of academics and other authors, to rewrite previously published materials to sidestep self-plagiarism. Students placing trust in online paraphrasing tools as an easy way of complying with the requirement for originality in submissions are at risk in terms of the quality of the output generated and possibly of not achieving the learning outcomes as they may not fully understand the information they have compiled. There are further risks relating to the legitimacy of the outputs in terms of academic integrity and plagiarism. The purpose of this paper is to highlight the existence, development, use and detection of use of Internet based paraphrasing tools. To demonstrate the dangers in using paraphrasing tools an experiment was conducted using some easily accessible Internet-based paraphrasing tools to process part of an existing publication. Two sites are compared to demonstrate the types of differences that exist in the quality of the output from certain paraphrasing algorithms, and the present poor performance of online originality checking services such as Turnitin® to identify and link material processed via machine based paraphrasing tools. The implications for student skills in paraphrasing, academic integrity and the clues to assist staff in identifying the use of online paraphrasing tools are discussed. (shrink)

In this provocative book, Susan Bordo untangles the myths, ideologies, and pathologies of the modern female body. Bordo explores our tortured fascination with food, hunger, desire, and control, and its effects on women's lives.

The versatility and adaptability of information technology offer many potential benefits to society, its organisations and its citizens; but there are also many associated risks. The social and ethical implications of this technology warrant special attention and have resulted in the creation of information ethics as a discrete area complementary to business ethics. Simon Rogerson is Director of the Centre for Computing and Social Responsibility at De Montfort University, The Gateway, Leicester, LE1 9BH, UK.

“The overall goal of information ethics is to integrate information technology and human values in such a way that IT advances and protects human values rather than doing damage to them” (Simon Rogerson). We are pleased to present in this issue five papers from a recent European conference on information ethics edited and introduced by Simon Rogerson, Director of the Centre for Computing and Social Responsibility at De Montfort University, England.We are also pleased to announce a major new (...) feature of the Review, entitled Business Ethics on the Internet, which will be contributed from time to time by members of the Centre for Computing and Social Responsibility at De Montfort University. This will provide regular up‐to‐date information and comment on the resources which are becoming increasingly available on the Internet relating to the study of business ethics and the practice of ethical business. It will be launched in our July issue in an article entitled “Business Ethics on the Internet”. (shrink)

This paper will suggest a mapping for human dynamics to see where emerging digital technology currently and could further affect the dynamics of the human, technological and natural, and the cultural forms that define them. Emerging technology will be seen to reveal and surpass the limitations of human measures built on human abilities and perception. and the social structures that are derived from them. The formation of this conceptual mapping is based on the premise that digital technology has the ability (...) to better relay and hence refine dynamics working at points where culture is created and necessitated in our perception of a shared reality. Technology thus alleviates the layering, representation, labelling, and reification notions of culture that are based in human perceptual limitations. Information as referential will be seen against the tendency of technology to offer succinct mediation and direct actions as a format for any change and application with refined cultural constructions. The mapping presents a notion of homeostasis or more bereft of balance at the point where the proximal dynamics of the unit, that is, the individual, is closely supported by the technology with a changing orientation to the dynamics of a natural environment. The notion of a person as an individual is also reconsidered in terms of technology and how this changing definition is part of how we conceptualize a balanced world. Nonlinear mapping rendered in a complex will be introduced to align these mixed dynamics. Complex is here defined as a concurrence of dynamics evident in shifts of change that act as a whole and where each action affects the whole. As measures are revealed so, too, will be the source of notions of linearity and nonlinearity; mapping; point of view as a basis of complexity; and evolutionary theory as a function of a labeling of cultural dynamics.

The Software Engineering Code of Ethics and Professional Practice, intended as a standard for teaching and practicing software engineering, documents the ethical and professional obligations of software engineers. The code should instruct practitioners about the standards society expects them to meet, about what their peers strive for, and about what to expect of one another. In addition, the code should also inform the public about the responsibilities that are important to the profession. Adopted in 2000 by the IEEE Computer Society (...) and the ACM--two leading international computing societies--the code of ethics is intended as a guide for members of the evolving software engineering profession. The code was developed by a multinational task force with additional input from other professionals from industry, government posts, military installations, and educational professions. (shrink)

Violence and the Remaking of a Self Susan J. Brison. Political activism (including lobbying for new legislation, speaking out, educating others, helping survivors) can also help to undo the double bind of self-blame versus helplessness.

To explain the causal relation between institutional rules and people’s actions and expectations, Searle relies upon his concept of the Background, the thesis that intentional states function only given a background of capacities that do not themselves consist in intentional phenomena. Any sentence, for instance, only acquires truth conditions or other conditions of satisfaction against a background of capacities, dispositions, know-how, etc. that are not themselves part of the content of the sentence. The Background also structures expectations. La Rouchefoucauld said, (...) for instance, that few people would fall in love if they had never read about it. (shrink)

The Flight to Objectivity offers a new reading of Descartes' Meditations informed by cultural history, psychoanalytic and cognitive psychology, and feminist thought.

On July 4, 1990, while on a morning walk in southern France, Susan Brison was attacked from behind, severely beaten, sexually assaulted, strangled to unconsciousness, and left for dead. She survived, but her world was destroyed. Her training as a philosopher could not help her make sense of things, and many of her fundamental assumptions about the nature of the self and the world it inhabits were shattered.At once a personal narrative of recovery and a philosophical exploration of trauma, (...) this book examines the undoing and remaking of a self in the aftermath of violence. It explores, from an interdisciplinary perspective, memory and truth, identity and self, autonomy and community. It offers imaginative access to the experience of a rape survivor as well as a reflective critique of a society in which women routinely fear and suffer sexual violence.As Brison observes, trauma disrupts memory, severs past from present, and incapacitates the ability to envision a future. Yet the act of bearing witness, she argues, facilitates recovery by integrating the experience into the survivor's life's story. She also argues for the importance, as well as the hazards, of using first-person narratives in understanding not only trauma, but also larger philosophical questions about what we can know and how we should live.Bravely and beautifully written, Aftermath is that rare book that is an illustration of its own arguments.

Students, the future Information and Communication Technology (ICT) professionals, are often perceived to have little understanding of the ethical issues associated with the use of ICTs. There is a growing recognition that the moral issues associated with the use of the new technologies should be brought to the attention of students. Furthermore, they should be encouraged to explore and think more deeply about the social and legal consequences of the use of ICTs. This paper describes the development of a tool (...) designed to raise students’ awareness of the social impact of ICTs. The tool offers guidance to students undertaking computing and computer-related courses when considering the social, legal and professional implications of the actions of participants in situations of ethical conflict. However, unlike previous work in this field, this tool is not based on an artificial intelligence paradigm. Aspects of the theoretical basis for the design of the tool and the tool’s practical development are discussed. Preliminary results from the testing of the tool are also discussed. (shrink)

The concept of "fitness" is a notion of central importance to evolutionary theory. Yet the interpretation of this concept and its role in explanations of evolutionary phenomena have remained obscure. We provide a propensity interpretation of fitness, which we argue captures the intended reference of this term as it is used by evolutionary theorists. Using the propensity interpretation of fitness, we provide a Hempelian reconstruction of explanations of evolutionary phenomena, and we show why charges of circularity which have been levelled (...) against explanations in evolutionary theory are mistaken. Finally, we provide a definition of natural selection which follows from the propensity interpretation of fitness, and which handles all the types of selection discussed by biologists, thus improving on extant definitions.

The United States Government does not mandate that US based firms follow US social and environmental law in foreign markets. However, because many developing countries do not have strong human rights, labor, and environmental laws, many multinationals have adopted voluntary corporate responsibility initiatives to self-regulate their overseas social and environmental practices. This article argues that voluntary actions, while important, are insufficient to address the magnitude of problems companies confront as they operate in developing countries where governance is often inadequate. The (...) United States can do more to ensure that its multinationals act responsibly everywhere they operate. First, policymakers should define the social and environmental responsibilities of global companies. They must consistently make their expectations for global business clear – and underscore that this objective can often be accomplished without mandates. Second, the US should closely examine the policies that undermine global Corporate Social Responsibility (CSR) and address the many conflicting signals sent by policymakers. Third, the President should make the US government a CSR model by examining how to use its purchasing power to promote human rights. Finally, the US government should require pension funds to report on the social and environmental consequences of their investments. In these ways, Americans can mind our business – and thus make sure that US based firms do not undermine social and environmental progress when they operate in the developing world. (shrink)

A defendant’s failure to show remorse is one of the most powerful factors in criminal sentencing, including capital sentencing. Yet there is currently no evidence that remorse can be accurately evaluated in a courtroom. Conversely there is evidence that race and other impermissible factors create hurdles to evaluating remorse. There is thus an urgent need for studies about whether and how remorse can be accurately evaluated. Moreover, there is little evidence that remorse is correlated with future law-abiding behavior or other (...) legitimate penal purposes, and, in fact, there is evidence that remorse is often conflated with shame, which is correlated with increased future criminality. More accurate information on the nature and evaluation of remorse can be used to reform the criminal justice system. (shrink)

Detecting contract cheating in written submissions can be difficult beyond direct plagiarism detectable via technology. Successfully identifying potential cases of contract cheating in written work such as essays and reports is largely dependent on the experience of assessors and knowledge of student. It is further dependent on their familiarity with the patterns and clues evident in sections of body text and reference materials to identify irregularities. Consequently, some knowledge of what the patterns and clues look like is required. This paper (...) documents how to identify some of the patterns and clues observed in essay and report submissions. Effective assessment design with specific contextual requirements make irregularities easier to detect and interpret. The irregularities identified were confirmed as instances of contract cheating through conversations held with postgraduate students. An essential element of the conversations was the evidence presented for discussion. Irregularities were noted on a pro-forma specifically developed for this purpose. Patterns identified include misrepresented bibliographic data, inappropriate references, irrelevant material and generalised text that did not address the assessment question or grading criteria. The validated patterns formed the basis of identifying potential instances of contract cheating in later submissions. Timely conversations with students before the end of semester are essential to determining whether the patterns and clues link to poor knowledge of academic writing conventions or classified as contract cheating necessitating the application of appropriate penalties under institutional policies and procedures.

Dehaene (this volume) articulates a naturalistic approach to the cognitive foundations of mathematics. Further, he argues that the ‘number line’ (analog magnitude) system of representation is the evolutionary and ontogenetic foundation of numerical concepts. Here I endorse Dehaene’s naturalistic stance and also his characterization of analog magnitude number representations. Although analog magnitude representations are part of the evolutionary foundations of numerical concepts, I argue that they are unlikely to be part of the ontogenetic foundations of the capacity to represent natural (...) number. Rather, the developmental source of explicit integer list representations of number are more likely to be systems such as the object–file representations that articulate mid–level object based attention, systems that build parallel representations of small sets of individuals.

This study investigates the effectiveness of pedagogical practices used to teach business ethics. The business community has greatly increased its demands for better ethics education in business programs. Educators have generally agreed that the ethical principles of business people have declined. It is important, then, to examine how common methods of instruction used in business ethics could contribute to the development of higher levels of moral judgment competence for students. To determine the effectiveness of these methods, moral judgment competence levels (...) for undergraduate and graduate students from three institutions were measured and compared based upon the pedagogical method used in a business class. Significant differences were found for moral reasoning and moral competence scores depending on the method used for ethics instruction. Students in classes with more highly integrated ethics coverage scored higher in moral reasoning and moral competence. (shrink)

Conventional wisdom and commonsense morality tend to take the integrity of persons for granted. But for people in systematically unjust societies, self-respect and human dignity may prove to be impossible dreams.Susan Babbitt explores the implications of this insight, arguing that in the face of systemic injustice, individual and social rationality may require the transformation rather than the realization of deep-seated aims, interests, and values. In particular, under such conditions, she argues, the cultivation and ongoing exercise of moral imagination is (...) necessary to discover and defend a more humane social vision. Impossible Dreams is one of those rare books that fruitfully combines discourses that were previously largely separate: feminist and antiracist political theory, analytic ethics and philosophy of mind, and a wide range of non-philosophical literature on the lives of oppressed peoples around the world. It is both an object lesson in reaching across academic barriers and a demonstration of how the best of feminist philosophy can be in conversation with the best of “mainstream” philosophy—as well as affect the lives of real people.

Democratic governments might be required by law to disseminate information to the people. This is called governmental transparency. What is the burden of transparency? We propose a “pragmatic information theory of communication” that places information accessibility as a foundation of transparency. Using a game model—the Transparency Game—we show that the pragmatic theory is the only one that makes it difficult for governments to appear transparent while not actually being transparent. There are two important consequences of understanding transparency through the theory: (...) Accessible information must be actionable, and cognitive science plays a vital role in assessing the accessibility of information. These consequences can have implications for public policies that promote transparency. (shrink)

The purpose of this article is to discuss an external whistleblowing event that occurred after all internal whistleblowing through the hierarchy of the organization had failed. It is argued that an organization that does not support those that whistle blow because of violation of professional standards is indicative of a failure of organizational ethics. Several ways to build an ethics infrastructure that could reduce the need to resort to external whistleblowing are discussed. A relational ethics approach is presented as a (...) way to eliminate the negative consequences of whistleblowing by fostering an interdependent moral community to address ethical concerns. (shrink)
