This paper develops the outlines of a pragmatic, adaptive management-based approach toward the control of invasive nonnative species (INS) through a case study of Kings Bay/Crystal River, a large artesian springs ecosystem that is one of Florida’s most important habitats for endangered West Indian manatees (Trichechus manatus). Building upon recent critiques of invasion biology, principles of adaptive management, and our own interview and participant–observer research, we argue that this case study represents an example in which rigid application of invasion biology’s (...) a␣priori imperative to minimize INS has produced counterproductive results from both an ecological and social standpoint. As such, we recommend that INS control in Kings Bay should be relaxed in conjunction with an overall program of adaptive ecosystem management that includes meaningful participation and input from non-institutional stakeholders. However, we also note that adaptive management and INS control are by no means mutually exclusive, in Kings Bay or elsewhere. Instead, we suggest that adaptive management offers a means by which INS control efforts can emerge from—and be evaluated through—ongoing scientific research and participatory dialogue about the condition of specific places, rather than non-contextual assumptions about the harmfulness of INS as a general class.

C. Stephen Evans explains and defends Kierkegaard's account of moral obligations as rooted in God's commands, the fundamental command being `You shall love your neighbour as yourself'. The work will be of interest not only to those interested in Kierkegaard, but also to those interested in the relation between ethics and religion, especially questions about whether morality can or must have a religious foundation. As well as providing a comprehensive reading of Kierkegaard as an ethical thinker, Evans (...) puts him into conversation with contemporary moral theorists. Kierkegaard's divine command theory is shown to be an account that safeguards human flourishing, as well as protecting the proper relations between religion and state in a pluralistic society.

Dienes' & Perner's proposals are discussed in relation to the distinction between explicit and implicit systems of thinking. Evans and Over (1996) propose that explicit processing resources are required for hypothetical thinking, in which mental models of possible world states are constructed. Such thinking requires representations in which the individuals' propositional attitudes including relevant beliefs and goals are made fully explicit.
'IF' is one of the most important and interesting words in the English language, being used to express hypothetical thought. The use of conditionals such as 'if' also distinguishes human intelligence from that of all other animals. In this volume, Jonathan Evans and David Over present a new theoretical approach to understanding hypothetical thought. The book draws on studies from the psychology of judgement and decision making, as well as philosophical logic.
Was love invented by European poets in the middle ages, as C. S. Lewis claimed, or is it part of human nature? Will winning the lottery really make you happy? Is it possible to build robots that have feelings? These are just some of the intriguing questions explored in this new guide to the latest thinking about the emotions. Drawing on a wide range of scientific research, from anthropology and psychology to neuroscience and artificial intelligence, Emotion: The Science of Sentiment (...) takes the reader on a fascinating journey into the human heart. Illustrating his points with entertaining examples from fiction, film, and popular culture, Dylan Evans ranges from the evolution of the emotions to the nature of love and happiness to the language of feelings, offering readers the most recent thinking on real life topics that touch us all. But Emotion is also a book filled with surprises. Readers will discover, for instance, that the basic emotions are felt the world over--whether we live in the shadow of Times Square or in the depths of the rain forest, we all feel the emotions of disgust, joy, surprise, anger, fear, and distress. We find out that, according to research, winning the lottery does not cause a lasting increase in happiness--a short-lived euphoria is followed in almost every case with a return to our usual emotional state, if not worse. And we meet Kismet, an MIT robot that can express a wide range of emotions, from fear to happiness. Fun to read and based on the latest scientific thinking, here is a stimulating look at our emotions. (shrink)
This brief paperback is designed for symbolic/formal logic courses. It features the tree method proof system developed by Jeffrey. The new edition contains many more examples and exercises and is reorganized for greater accessibility.
Turning Images in Philosophy, Science, and Religion: A New Book of Nature brings together new essays addressing the role of images and imagination recruited in the perennial debates surrounding nature, mind, and God. -/- The debate between "new atheists" and religious apologists today is often hostile. This book sets a new tone by locating the debate between theism and naturalism (most "new atheists" are self-described "naturalists") in the broader context of reflection on imagination and aesthetics. The eleven essays will be (...) of interest to anyone who is fascinated by the power of imagination and the role of aesthetics in deciding between worldviews or philosophies of nature. Representing a variety of points of view, authors include outstanding philosophers of religion and of science, a distinguished art historian, and a visual artist. -/- The book begins with Martin Kemp's essay on the work of the biologist, mathematician and classical scholar D'Arcy Wentworth Thompson in which Kemp develops the idea of "structural intuitions and a critique of reductive thinking about the natural world. This is followed by Geoffrey Gorham's overview and analysis of images of nature and God found in early modern science and philosophy. Anthony O'Hear questions a reductive, naturalist account of the origin of mind and values. Dale Jacquette offers a thoroughgoing naturalistic philosophy of the emergence of intentionality and a unique argument about the emergence of art and the aesthetic appreciation of nature. E.J. Lowe brings to light some challenges facing naturalistic approaches to human imaginative sensibility. Douglas Hedley articulates and defends a cognitive account of imagination, highlighting some of the difficulties confronting naturalism. Daniel N. Robinson offers a sweeping treatment of nature and naturalism, historically engaging Aristotle, Kant, Hegel and others. Conor Cunningham provides an aggressive critique of contemporary naturalism. Gordon Graham investigates the resources of naturalism in accounting for our sense of the sacred. Mark Wynn provides a subtle understanding of imagination and perception, suggesting how these may play into the theism - naturalism debate. The book concludes with Jil Evans' reflections on how images of the Galapagos Islands have been employed philosophically to picture either a naturalist or theistic image of nature. (shrink)
Richard Gale, in On the Nature and Existence of God, offers several reasons why an “historical-cum-indexical” theory of reference cannot be appropriate in explaining how people refer to God. The present paper identifies five distinct lines of argument in Gale, attempts to clarify several important desiderata for a successful theory of reference, and argues that Gale fails to discharge the burden of proof he has assumed, leaving the most important features of Alston’s “direct reference” theory untouched. Nevertheless, it is conceded (...) that some consequences of Alston’s theory are quite counter-intuitive. The paper therefore concludes with a consideration of two alternatives: either taking a hard, Alstonian line in conflict with people’s linguistic intuitions, or striking a compromise with descriptivism along lines similar to those found in Gareth Evans’s paper, “The Causal Theory of Names.”.

This authoritative and lively exploration of the theories of contemporary feminism covers all the major variants of feminist political thought from the "traditional" schools of the women's movement-particularly radical, liberal, and socialist-to today's postmodern texts. Feminist Theory Today examines the epistemological challenge from critical legal theory and postmodernist thought; the divergences within, as well as between, feminist schools; and the protests from women marginalized by the feminist movement, including those who are lesbian and those who are black. It also interrogates (...) the dialectic equality and difference and reconceptualizes this pervasive tenet of feminist thought. Author Judith Evans documents the changes in socialist feminism from its revolutionary origins to its current focus on modifying liberal democratic forms. Students and teachers of women's studies, sociology, and political theory will find this an authoritative and lively exploration of the theories of contemporary feminism. It is also essential reading for anyone seeking to understand why the women's movement is as it is today. (shrink)

Richard Jeffrey is beyond dispute one of the most distinguished and influential philosophers working in the field of decision theory and the theory of knowledge. His work is distinctive in showing the interplay of epistemological concerns with probability and utility theory. Not only has he made use of standard probabilistic and decision theoretic tools to clarify concepts of evidential support and informed choice, he has also proposed significant modifications of the standard Bayesian position in order that it provide a (...) better fit with actual human experience. Probability logic is viewed not as a source of judgment but as a framework for explaining the implications of probabilistic judgments and their mutual compatability This collection of essays spans a period of some 35 years and includes what have become some of the classic works in the literature. There is also one completely new piece, while in many instances Jeffrey includes afterthoughts on the older essays. (shrink)
Covering the work of Frege, Russell, and more recent work on singular reference, this important book examines the concepts of perceptually-based demonstrative identification, thought about oneself, and recognition-based demonstrative identification.
Both Nietzsche and Merleau-Ponty repudiate the mirror view of perception and embrace what Nietzsche refers to as solar love or creative perception. I argue that Merleau-Ponty thinks of this type of perception primarily in terms of convergence and Nietzsche in terms of divergence. I then show how, contrary to their own emphases, Merleau-Ponty's notion of flesh and Nietzsche's idea of chaos suggest that convergence and divergence are abstractions from an ontologically prior realm of hybrid perceptions. In this realm, each perception (...) is shot through with the others, simultaneously inside and outside one another. The creative tension among these perceptions continually produces new perspectives or voices, that is, a realm whose very being is metamorphosis. Moreover, this realm of hybrid perceptions suggests a political principle that might prove attractive for communities in an age of diversity and cultural hybridity. (shrink)
Many philosophers and psychologists now argue that emotions play a vital role in reasoning. This paper explores one particular way of elucidating how emotions help reason which may be dubbed ?the search hypothesis of emotion?. After outlining the search hypothesis of emotion and dispensing with a red herring that has marred previous statements of the hypothesis, I discuss two alternative readings of the search hypothesis. It is argued that the search hypothesis must be construed as an account of what emotions (...) typically do, rather than as a definition of emotion. Even as an account of what emotions typically do, the search hypothesis can only be evaluated in the context of a specific theory of what emotions are. 1 Introduction 2 The search hypothesis of emotion 3 A red herring: the frame problem 4 The search problem 5 Two readings of the search hypothesis 6 Two final remarks 7 Conclusion.

In this article I explore the underlying political philosophy of public bioethics by comparing it to technocratic authority, particularly the technocratic authority claimed by economists in Mexico in the 1980s and 1990s. I find that public bioethics - at least in the dominant forms - is implicitly designed for and tries to use technocratic authority. I examine how this type of bioethics emerged and has continued. I finish by arguing that, as claims to technocratic authority go, bioethics is in an (...) incredibly weak position, which partly explains why it has never gained the degree of public legitimacy that other technocracies have gained. I conclude by arguing for a "technocracy-lite" orientation for public bioethics. (shrink)
: What is truly beautiful? For Søren Kierkegaard the beautiful is to be found in an integrated self, one that is freely chosen. This article explores Kierkegaard's "aesthetic" stage of existence through the character of Augusto Pérez, the protagonist of Miguel de Unamuno's novel, Niebla. After establishing a solid link between Unamuno and Kierkegaard, Kierkegaard's "ethical" stage is used to critique the "aesthetic" stage on aesthetic grounds, on the basis of the beauty found in life's work, a calling. The conclusion (...) is that the sphere of the "aesthetic" does not achieve Kierkegaard's "aesthetics" of an integrated, fully existing self. (shrink)
Isaac Levi and I have different views of probability and decision making. Here, without addressing the merits, I will try to answer some questions recently asked by Levi (1985) about what my view is, and how it relates to his.
The Fitzgerald-Lorentz contraction hypothesis, proposed as an explanation of the Michelson-Morley result, fails to account for the Kennedy-Thorndike result. Hence, Grünbaum argues, the hypothesis has been falsified. However, the contraction hypothesis as formulated by Lorentz is false for the very fundamental reason that it entails a contradiction, namely, the consequence that light waves must have a variable velocity along what by definition is taken to be a rest length. Furthermore, the attempt to resolve this contradiction by coupling the Fitzgerald-Lorentz contraction (...) with the hypothesis that clock rates are a function of velocity, is open to a sound, methodological objection. The Michelson-Morley result is fully satisfied, provided only that the lengths of the interferometer arms, in the longitudinal and transverse positions, are thought to be related to one another in a certain ratio, and this ratio may be interpreted as a contraction in both arms. Since this twofold contraction hypothesis suffices to explain both the Michelson-Morley and the Kennedy-Thorndike results, and since it entails no contradiction, there is no need to correct both the length of rods and the rate of clocks. Therefore, the combined clock-rod hypothesis, and with it the Fitzgerald-Lorentz contraction hypothesis, must be rejected. (shrink)
Logicism Lite counts number‐theoretical laws as logical for the same sort of reason for which physical laws are counted as as empirical: because of the character of the data they are responsible to. In the case of number theory these are the data verifying or falsifying the simplest equations, which Logicism Lite counts as true or false depending on the logical validity or invalidity of first‐order argument forms in which no numbertheoretical notation appears.
Medicine, as Byron Good argues, reconstitutes thehuman body of our daily experience as a medical body,unfamiliar outside medicine. This reconstitution can be seen intwo ways: (i) as a salutary reminder of the extent to which thereality even of the human body is constructed; and (ii) as anarena for what Stephen Toulmin distinguishes as theintersection of natural science and history, in which many ofphilosophy''s traditional (and traditionally abstract) questionsare given concrete and urgent form.This paper begins by examining a number of dualities (...) between themedical body and the body familiar in daily experience. Toulmin''s epistemological analysis of clinical medicine ascombining both universal and existential knowledge is thenconsidered. Their expression, in terms of attention,respectively, to natural science and to personal history, isexplored through the epistemological contrasts between themedical body and the familiar body, noting the traditionalphilosophical questions which they in turn illustrate.

This paper argues that mathematics education curricular policy has slowly effected a reversal in the relationship between mathematics and its publics: from mathematics assuming its users to mathematics defined by its (supposed) users. Mathematics education research itself, its contribution to challenging the former notwithstanding, has often unwittingly supported this shift. While in the mid 1980s the mathematics educators propagating the teaching of mathematics by applications represented a small and unique group, by the mid 1990s those advocating teaching mathematics this way (...) had grown appreciably. A characteristic of this change in conviction is the emphasis on the importance of the context of mathematical thinking and problem-solving. Paradoxically, the consequences of the coupling of mathematics, both with utilitarianism,as other have argued, and with essentialism,as we argue in this paper, have been to narrow its scope (e.g. to a narrow version of 'numeracy') and to distance mathematics from its publics. In the paper we argue that action is needed to counter these trends, and to develop the area of the public understanding of mathematics. Otherwise policies aiming simply to 'popularize' mathematics might exacerbate these consequences. In particular, research is necessary along the lines followed by the social studies of science. For such research-by posing as pertinent the question of describing and accounting for differences between practices of knowledge production, dissemination and use-can help to avoid the assumption of a unique essence of some unitary culture called 'mathematics' and therefore a public (or publics) separated from it.

The following paper continues discussions within this journal about how the work of Delueze and Guattari can inform radical pedagogy. Building primarily on Noel Gough's 2004 paper, we take up the challenge to move towards a more creative form of 'becoming cyborg' in our teaching. In contrast to work that has focused on Deleuzian theories of the rhizome, we deploy Guattari's work on institutional schizoanalysis to explore the role of group creativity in radical pedagogy. The institutional therapies of Felix Guattari's (...) schizoanalytic practice in the 1950s and 1960s and, before him, the Francophone educationalist Celestin Freinet, who founded the Modern School Movement, are explored and used to illuminate examples of some of our own attempts to set the classroom up as a space for collective engagement. We conclude by exploring how this understanding of the class as subject group may be used to mobilise action and de-stabilise the coordinates of existing academic divisions of labour. (shrink)
: Like the goddess Demeter, Diotima from Mantineia, the prophetess who teaches Socrates about eros and the "rites of love" in Plato's Symposium, was a mystagogue who initiated individuals into her mysteries, mediating to humans esoteric knowledge of the divine. The dialogue, including Diotima's speech, contains religious and mystical language, some of which specifically evokes the female-centered yearly celebrations of Demeter at Eleusis. In this essay, I contextualize the worship of Demeter within the larger system of classical Athenian practices, and (...) propose that Plato borrowed Eleusinian language because it criticized conventional notions of the divine, thereby allowing him to reimagine the possibilities for the philosophical process among humans.

Many bioethics questions are resistant to journalistic exploration on account of their inherently philosophical dimensions. Such dimensions are ill-suited to what we may term the internal goods (in MacIntyre's sense) of the newspapers and mass media generally, which constrain newspaper coverage to an abbreviated form of narrative that, whilst not in itself objectionable, is nonetheless inimical to the conduct of philosophical reflection. The internal goods of academic bioethics, by contrast, include attention to philosophical questions inherent in bioethical issues and value-enquiry. (...) The danger for bioethics is that its agenda for reflective enquiry will, if dictated by this abbreviated narrative, be distorted in terms of both range and priorities, to the inevitable neglect of questions having a philosophical dimension to them. This danger can be avoided by a constructive partnership between the media and academic bioethics. The success of this partnership relies on four suggested provisos, for the meeting of which both journalists and academics bear responsibility. (shrink)
The business world is not a separate universe of economic values and goals distinct from society, but an aspect of the behaviour of society as a whole. Ethics cannot be a cosmetic applied to established practice in the business world, a mere restraint on the unsocial or criminal behaviour of managers or a pragmatic response to consumer pressure. The author argues for a Total Ethics concept analogous to Zero Defects concepts in operations management. This ethic should form the foundation of (...) the organisation's mission and permeate its statements of business objectives. If the ethic is to serve the common good of all who have an interest in the business, then all the stakeholders, not just those with a financial interest, must contribute to the business objectives and exercise some control.

Recruiting patients into clinical research is essential for the advancement of medical knowledge. However, when the physician undertaking the care of the patient is also responsible for recruitment into clinical research, a situation arises of an inter-role breach of confidentiality which is distinguishable from other conflicts of interest. Such discord arises as the physician utilizes confidential information obtained within the therapeutic relationship beyond its primary objective, and safeguards ought to be observed in order to avert this important, and generally overlooked, (...) problem. The moral worth of the pledge of confidentiality is based not on its innate value but on its being a promise on which subsequent interactions and disclosures are founded. Within the patient-doctor interaction, confidentiality is an important facet of the promised fidelity and, as such, a loose interpretation of the notion threatens the essence of the relationship, and any violation thereof requires compelling moral justification. To avoid conflict, patients' confidential information ought not be used for the purpose of recruitment, which needs to be undertaken through general education and non-directed appeals, and a preliminary consent to be approached for research should be obtained from the patient prior to her being identified as a suitable research subject. Securing this prior consent would avoid one source of potential, albeit unintended, coercion. (shrink)
We construct a stable one-based, trivial theory with a reduct which is not trivial. This answers a question of John B. Goode. Using this, we construct a stable theory which is n-ample for all natural numbers n, and does not interpret an infinite group.
For thousands of years, many Western thinkers have assumed that emotions are, at best, harmless luxuries, and at worst outright obstacles to intelligent action. In the past decade, however, scientists and philosophers have begun to challenge this 'negative view of emotion'. Neuroscientists, psychologists and researchers in artificial intelligence now agree that emotions are vital to intelligent action. Evolutionary considerations have played a vital role in this shift to a more positive view of emotion. -/- This book brings together some of (...) the leading thinkers about emotion from a variety of disciplines. In a series of fascinating and challenging essays, they examine the role that evolutionary considerations can play in helping us to understand the role of emotions in rational thought and decision-making. How should we understand the evolutionary role of emotions? And can this explain the relationship between emotions and rationality? (shrink)
An ω-categorical supersimple group is finite-by-abelian-by-finite, and has finite SU-rank. Every definable subgroup is commensurable with an acl( $\emptyset$ )-definable subgroup. Every finitely based regular type in a CM-trivial ω-categorical simple theory is non-orthogonal to a type of SU-rank 1. In particular, a supersimple ω-categorical CM-trivial theory has finite SU-rank.
