In a series of articles, Rieppel (2005, Biol. Philos. 20:465–487; 2006a, Cladistics 22:186–197; 2006b, Systematist 26:5–9), Keller et al. (2003, Bot. Rev. 69:93–110), and Nixon and Carpenter (2000, Cladistics 16:298–318) criticize the philosophical foundations of the PhyloCode. They argue that species and higher taxa are not individuals, and they reject the view that taxon names are rigid designators. Furthermore, they charge supporters of the individuality thesis and rigid designator theory with assuming essentialism, committing logical inconsistencies, and offering proposals that render (...) taxonomy untestable. These charges are unsound. Such charges turn on confusions over rigid designator theory and the distinction between kinds and individuals. In addition, Rieppel’s, Keller et al.’s, and Nixon and Carpenter’s proposed alternatives are no better and have their own problems. The individuality thesis and rigid designator theory should not be quickly abandoned. [Individuals; kinds; PhyloCode; rigid designators; species; taxa; taxon names.]. (shrink)

It is commonly held that objects in the world form natural kinds. Rabbits form a natural kind and so do all pieces of gold. The traditional account of natural kinds asserts that the members of a kind share a common essence. The essence of gold, for example, is its unique atomic structure. That structure occurs in all and only pieces of gold, and it is a property that all pieces of gold must have.

In this essay I first provide an analysis of various community concepts. Second, I evaluate two of the most serious challenges to the existence of communities—gradient and paleoecological analysis respectively—arguing that, properly understood, neither threatens the existence of communities construed interactively. Finally, I apply the same interactive approach to ecosystem ecology, arguing that ecosystems may exist robustly as well. ‡I would like to thank to the participants at the Ecology and Environmental Ethics Conference at the University of Utah, the Philosophy (...) of Ecology Conference hosted by the University of Brisbane, and those participants in a session at the Philosophy of Science Association Meeting in Vancouver, British Columbia for helpful discussions of this essay.

This book offers a systematic framework for thinking about the relationship between language and technology and an argument for interweaving thinking about technology with thinking about language. The main claim of philosophy of technology—that technologies are not mere tools and artefacts not mere things, but crucially and significantly shape what we perceive, do, and are—is re-thought in a way that accounts for the role of language in human technological experiences and practices. Engaging with work by Wittgenstein, Heidegger, McLuhan, Searle, Ihde, (...) Latour, Ricoeur, and many others, the author critically responds to, and constructs a synthesis of, three "extreme", idealtype, untenable positions: only humans speak and neither language nor technologies speak, only language speaks and neither humans nor technologies speak, and only technology speaks and neither humans nor language speak. The construction of this synthesis goes hand in hand with a narrative about subjects and objects that become entangled and constitute one another. Using Words and Things thus draws in central discussions from other subdisciplines in philosophy, such as philosophy of language, epistemology, and metaphysics, to offer an original theory of the relationship between language and technology centered on use, performance, and narrative, and taking a transcendental turn.

The spectre of the repugnant conclusion and the search for a population axiology that avoids it has endured as a focus of population ethics. This is in part because the repugnant conclusion is often interpreted as a defining problem for totalism, while the implications of averagism and related views are taken to illustrate the theoretical cost of avoiding the repugnant conclusion. However, we show that this interpretation cannot be sustained unless one focuses only on a special case of the repugnant (...) conclusion: namely, the subset of instances of the repugnant conclusion where there is no portion of the population unaffected by the choice between population outcomes (as in Derek Parfit’s original illustration). To avoid an inappropriate focus on only this proper subset of instances of the repugnant conclusion, we formulate a general characterization of the repugnant conclusion. We then prove formally that all leading welfarist axiologies imply this conclusion, including averagism and Ng’s Theory X0 , including probabilistic and ‘very repugnant’ variants that involve the addition of negative lives. We then prove that the full range of axiologies considered by population ethics each imply an extended version of the repugnant conclusion, including axiologies that are incomplete, intransitive, rank-dependent, person-affecting, and/or pluralist. The upshot is that the repugnant conclusion does not ultimately tell against any approach to axiology, and the methodological requirement to avoid the repugnant conclusion should be dropped from population axiology.

This second edition of the book contains a new chapter on the notions of natural-kind words and natural kinds.

This book outlines and evaluates the principal strands of critical legal studies, and achieves much more as well.

This book scrutinizes recent work in phonological theory from the perspective of Chomskyan generative linguistics and argues that progress in the field depends on taking seriously the idea that phonology is best studied as a mental computational system derived from an innate base, phonological Universal Grammar. Two simple problems of phonological analysis provide a frame for a variety of topics throughout the book. The competence-performance distinction and markedness theory are both addressed in some detail, especially with reference to phonological acquisition. (...) Several aspects of Optimality Theory, including the use of Output-Output Correspondence, functionalist argumentation and dependence on typological justification are critiqued. The authors draw on their expertise in historical linguistics to argue that diachronic evidence is often mis-used to bolster phonological arguments, and they present a vision of the proper use of such evidence. Issues of general interest for cognitive scientists, such as whether categories are discrete and whether mental computation is probabilistic are also addressed. The book ends with concrete proposals to guide future phonological research.The breadth and depth of the discussion, ranging from details of current analyses to the philosophical underpinnings of linguistic science, is presented in a direct style with as little recourse to technical language as possible.

Formal arguments have proven that avoiding the Repugnant Conclusion is impossible without rejecting one or more highly plausible population principles. To many, such proofs establish not only a deep challenge for axiology, but also pose an important practical problem of how policymaking can confidently proceed without resolving any of the central questions of population ethics. Here we offer deflationary responses: first to the practical challenge, and then to the more fundamental challenge for axiology. Regarding the practical challenge, we provide an (...) overview of recent literature that explores the implications for public policy of the Repugnant Conclusion and related puzzles within population ethics, and shows that there is more commonality in the implications of different population axiologies than is generally recognized. The upshot is that uncertainty about population ethics presents no important problem for policymaking, and the importance of population ethics to policymaking has been overstated. We then turn to more fundamental issues about axiology, and describe a new series of formal proofs that undermine the idea that any plausible axiology could avoid the Repugnant Conclusion, including those that are assumed to avoid it in the literature. The philosophical upshot is that the Repugnant Conclusion cannot plausibly be avoided, and so it is a mistake to assume as a constraint on a plausible axiology that it must be avoided, as is assumed by most of the literature in population ethics, including by all of the fundamental impossibility theorems.

To surmount the notorious difficulties of defining life, we should evaluate theories of life not by whether they provide necessary and sufficient conditions for our current preconceptions about life but by how well they explain living phenomena and how satisfactorily they resolve puzzles about life. On these grounds, the theory of life as supple adaptation (Bedau 1996) gets support from its natural and compelling resolutions of the following four puzzles: (1) How are different forms of life at different levels of (...) the vital hierarchy related? (2) Is there a continuum between life and non-life? (3) Does life essentially concern a living entity’s material composition or its form? (4) Are life and mind intrinsically connected? (shrink)

We have studied the adaptation of mutation rates in a simple model of evolution. The model consists of a two-dimensional world with a periodically replenished resource and a uctuating population of evolving agents whose survival and reproduction are an implicit a function of their success at nding resources and their internal metabolism. Earlier work suggested that mutation rate is a control parameter that governs a transition between two qualitatively di erent kinds of complex adaptive systems, and that the power of (...) adaptive evolution is maximized when the mutation rate is around this transition. This paper provides evidence that evolving mutation rates adapt to values around this transition. Furthermore, the mutation rates adapt up (or down) as the evolutionary demands for novelty (or memory) increase. (shrink)

Self-representational theories of consciousness hold that a mental phenomenon is conscious if, and only if, it presents, among other things, itself. But in conscious perception one may lose oneself in the object perceived and not be aware of one’s perceiving. The paper develops a Brentano-inspired response to this objection. He follows Aristotle in holding that one is aware of one’s perceiving only ‘on the side’: when one perceives something one’s perception neither is nor can become observation of itself. I argue (...) that the arguments Brentano gave for this claim in Psychology from an Empirical Standpoint are wanting. However, a promising argument emerges if one takes Brentano’s conception of noticing into account. (shrink)

The globalized nature of modern organizations presents new and intimidating challenges for effective relationship building. Organizations and their employees are increasingly being asked to manage unfamiliar relationships with unfamiliar parties. These relationships not only involve working across different national cultures, but also dealing with different organizational cultures, different professional cultures and even different internal constituencies. Managing such differences demands trust. This book brings together research findings on organizational trust-building across cultures. Established trust scholars from around the world consider the development (...) and maintenance of trust between, for example, management consultants and their clients, senior international managers from different nationalities, different internal organizational groupings during times of change, international joint ventures, and service suppliers and the local communities they serve. These studies, set in a wide variety of national settings, are an important resource for academics, students and practitioners who wish to know more about the nature of cross-cultural trust-building in organizations"--Provided by publisher.

Agents need to be able to change their beliefs; in particular, they should be able to contract or remove a certain belief in order to restore consistency to their set of beliefs, and revise their beliefs by incorporating a new belief which may be inconsistent with their previous beliefs. An influential theory of belief change proposed by Alchourron, G¨ardenfors and Makinson (AGM) [1] describes postulates which a rational belief revision and contraction operations should satisfy. The AGM postulates have been perceived (...) as characterising idealised rational reasoners, and the corresponding belief change operations are considered unsuitable for implementable agents due to their high computational cost [3]. The main result of this paper is showing that an efficient (linear time) belief contraction operation nevertheless satisfies all but one of the AGM postulates for contraction. This contraction operation is defined for a realistic rule-based agent which can be seen as a reasoner in a very weak logic; although the agent’s beliefs are deductively closed with respect to this logic, checking consistency and tracing dependencies between beliefs is not computationally expensive. Finally, we give a non-standard definition of belief revision in terms of contraction for our agent. (shrink)

ABSTRACT We consider several ways in which a good understanding of modern techniques and principles in physics can elucidate ecology, and we focus on analogical reasoning between these two branches of science. Analogical reasoning requires an understanding of both sciences and an appreciation of the similarities and points of contact between the two. In the current ecological literature on the relationship between ecology and physics, there has been some misunderstanding about the nature of modern physics and its methods. Physics is (...) seen as being much cleaner and tidier than ecology. When compared to this idealized, fictional version of physics, ecology looks very different, and the prospect of ecology and physics learning from one another is questionable. We argue that physics, once properly understood, is more like ecology than ecologists have thus far appreciated. Physicists and ecologists can and do learn from each other, and, in this paper, we outline how analogical reasoning can facilitate such exchanges. (shrink)

Martin Heidegger’s Being and Time (1927) challenged earlier thinking about the basic structures of human being, our involvement in practical affairs, and our understanding of history, time, and being. Blitz clarifies Heidegger’s discussions, offers alternative analyses of phenomena central to Heidegger’s argument, and examines the connection between Heidegger’s position in Being and Time and his support of Nazism. As Blitz explains in his new afterword, “When I began to study Martin Heidegger nearly fifty years ago, my goal was to explore (...) the meaning of Being and Time for political philosophy. I wished to discover what it might offer for clarifying the grounds on which the basic concepts and alternatives of political philosophy rest. Would a close reading of it help us understand the questions of justice, freedom, the common good, natural rights, virtue, human happiness, and the philosophic life? These questions are as important today as they were then.” Although Blitz often questions and criticizes Heidegger’s views, he presents them with scrupulous care and clarity. Specialists and students in the areas of political theory, phenomenology, metaphysics, and moral philosophy will find Heidegger’s Being and Time & the Possibility of Political Philosophy an invaluable resource.

We use game theory and Santa Fe Artificial Stock Market, an agent-based model of an evolving stock market, to study the optimal frequency for traders to revise their market forecasting rules. We discover two things: There is a unique strategic Nash equilibrium in the game of choosing forecast revision rates, and this equilibrium is sub-optimal in the sense that traders’ earnings are not maximized an the market is inefficient. This strategic equilibrium is due to an analogue of the prisoner’s dilemma; (...) the optimal global state is unstable because each trader has too much incentive to ‘defect’ and use forecasting rules that pull the market into thesub-optimal equilibrium.

Macmurray provides a conceptual and personal reference point around which we can locate a tradition of social humanism that unfolds from the British idealists to the communitarians. Some communitarian themes appear in the thought of the idealists: these include a vitalist analysis of behaviour, a 'thick' view of the person, and a positive concept of freedom defined in relation to others. Macmurray developed these themes and introduced others largely as a result of reworking idealism so as to come to terms (...) with the crisis of reason associated with the First World War. He rejected objective idealism with its concept of absolute mind for a personal idealism that incorporated an action-based metaphysics. Doing so prompted him to adopt other communitarian themes: these include an appeal to friendship and love, a contrast between society and community, and an appeal to religion to transcend the limits of justice. While contemporary communitarians have inherited much from philosophers such as Macmurray, they have also developed the tradition of social humanism. Philosophers such as Sandel, Taylor and Walzer have done so through grappling with the implications of multiculturalism for the idea of a cosmopolitan community. Ethical socialists like Tony Blair and Raymond Plant have done so through grappling with issues such as a decline in solidarity as it influences the welfare state. (shrink)

It seems one can’t open a climbing magazine these days without encountering a barrage of duty statements such as “It is wrong to retro-bolt” or “It is wrong to bolt a new route too close to a naturally protected route”. Such statements are often referred to as examples of ethical debate, however, as we shall see, they are more properly referred to as moral debate. The distinction is not just a pedantic piece of linguistics either, it is, I believe, essential (...) to understanding the true nature of these disputes, and it is the nature of these disputes which I am concerned with in this article. The distinction between ethics and morality was first brought to my attention in an article by Dr Green called ‘The Ethics of Climbing’ in Screamer 9 (1981). In this article Dr Green explains how ‘ethics’ derives from the Greek ‘ethikos’ which pertains to the spirit of the thing in question, so the ethics of climbing are concerned with the spirit of climbing. ‘Morality’, on the other hand, is is derived from the Latin ‘moralis’ pertaining to right conduct, so a morality is a set of commands, usually used to encapsulate a particular ethic. Dr Green goes on to suggest that just as many Christians’ obsession with the ten commandments is symptomatic of a failure by those individuals to grasp the spirit or ethos of Christianity, so too modern rockclimbers’ obsession with the morals of climbing signifies a shift in the ethos of climbing. I wish to examine this claim a little more closely. I believe that the legitimate role of morals is in the teaching of ethics. For example, it would be difficult to teach a child the abstract ethos of “caring for your fellow human being’s welfare” without first giving some concrete examples in the form of commands such as “Don’t hit other children at school”. It is by learning these moral commands.. (shrink)

Philip Pettit’s neo-Roman republican theory of non-domination is billed as a more egalitarian alternative to classical liberal theories of non-interference. As a theory of geopolitical affairs, however, his republicanism fails to fulfill this egalitarian promise in ways that closely echo John Rawls’s liberal law of peoples. Pettit’s republican law of peoples is ill equipped to address structural sources of transnational and global domination because it exaggerates the ontological separateness of peoples, it overvalues the self-sufficiency of states for purposes of achieving (...) internal non-domination, and it conceives of domination too narrowly as an evil that must be intentionally or negligently imposed by identifiable agents.

We argue that psychological research can enhance the identification of reasoning errors and the development of an appropriate pedagogy to instruct people in how to avoid these errors. In this paper we identify some of the findings of psychologists that help explain some common fallacies, give examples of fallacies identified in the research that have not been typically identified in philosophy, and explore ways in which this research can enhance critical thinking instruction.

Most discussions of Kripke's Naming and Necessity focus either on Kripke's so-called "historical theory of reference" or his thesis that names are rigid designators. But in response to problems of the rigidity thesis Kripke later points out that his thesis about proper names is a stronger one: proper names are de jure rigid. This sets the agenda for my paper. Certain problems raised for Kripke's view show that the notion of de jure rigidity is in need of clarification. I will (...) try to clarify the notion of de jure rigidity by analyzing characterizations of it given in the literature. I will argue in particular that Kripke can count descriptive names as de jure rigid and that the concept of de jure rigidity should not be explained with recourse to the concept of a semantical rule. The second part of the paper is a critical discussion of arguments intended to show that proper names are not de jure rigid. I will show that these arguments are unconvincing by using Dummett's distinction between assertoric content and ingredient sense. (shrink)

“News! Oh! Yes, I always like news.” Throughout Emma, Jane Austen’s eponymous heroine repeatedly betrays her intense love of gossip. Other characters (notably, Miss Bates and Mr. Knightley) also indulge and rejoice in this style of conversation, as does the novel’s own narrator. In this chapter, the authors propose to examine the multifaceted and ambiguous role played by gossip in Emma, in light of the diverse opinions expressed by a number of critics and philosophers about the ethical and psychological significance (...) of this form of human discourse. They argue that Austen exhibits a fascinating, consistently ambivalent evaluative attitude toward the information-rich chitchat of her characters. She reveals a sensitivity to the moral dangers of gossip, as well as to what evolutionary psychologists have identified as its fundamental role in the regulation of human societies, and in the development of more indispensable forms of linguistic communication.

The dynamical patterns in mental phenomena have a characteristic suppleness&emdash;a looseness or softness that persistently resists precise formulation&emdash;which apparently underlies the frame problem of artificial intelligence. This suppleness also undermines contemporary philosophical functionalist attempts to define mental capacities. Living systems display an analogous form of supple dynamics. However, the supple dynamics of living systems have been captured in recent artificial life models, due to the emergent architecture of those models. This suggests that analogous emergent models might be able to explain (...) supple dynamics of mental phenomena. These emergent models of the supple mind, if successful, would refashion the nature of contemporary functionalism in the philosophy of mind. (shrink)
