A number of recent discussions have argued that George Price's equationfor representing evolutionary change is a powerful and illuminatingtool, especially in the context of debates about multiple levels ofselection. Our paper dissects Price's equation in detail, and comparesit to another statistical tool: the calculation and comparison ofaverage fitnesses. The relations between Price's equation and equationsfor evolutionary change using average fitness are closer than issometimes supposed. The two approaches achieve a similar kind ofstatistical summary of one generation of change, and they (...) achieve thisvia a similar loss of information about the underlying fitnessstructure.

Despite the fact that animal behavior involves a particularly powerful form of niche construction, few researchers have considered how the environmental impact of behavior may feed back to influence the evolution of the cognitive underpinnings of behavior. I explore a model that explicitly incorporates niche construction while tracking cognitive evolution. Agents and their stimuli are modeled as coevolving populations. The agents are born with “weights” attached to behaviors in a repertoire. Further, these agents are able to change these weights based (...) on previous success and an inherited learning parameter. Both the agent and the stimulus receive payoffs through a behavioral interaction . The behaving agent exhibits niche construction through its effects on stimuli , which can feed back to influence the value of different cognitive strategies. Here I focus on two forms of niche construction: the stimulus and responding agent have common interests and the stimulus and agent have dissimilar interests . The form of niche construction qualitatively affects cognitive evolution . Given a mutualism between the stimulus and responding agent, rapid learning and “fixed” behavioral distributions evolve. Given an antagonism between the stimulus and agent, slower learning and “flexible” behavioral distributions evolve. I discuss these results in light of findings from the fields of ethology, psychology, and evolutionary ecology. (shrink)

Altruism is generally understood to be behavior that benefits others at a personal cost to the behaving individual. However, within evolutionary biology, different authors have interpreted the concept of altruism differently, leading to dissimilar predictions about the evolution of altruistic behavior. Generally, different interpretations diverge on which party receives the benefit from altruism and on how the cost of altruism is assessed. Using a simple trait-group framework, we delineate the assumptions underlying different interpretations and show how they relate to one (...) another. We feel that a thorough examination of the connections between interpretations not only reveals why different authors have arrived at disparate conclusions about altruism, but also illuminates the conditions that are likely to favor the evolution of altruism.

Recent years have seen a renewed debate over the importance of groupselection, especially as it relates to the evolution of altruism. Onefeature of this debate has been disagreement over which kinds ofprocesses should be described in terms of selection at multiple levels,within and between groups. Adapting some earlier discussions, we presenta mathematical framework that can be used to explore the exactrelationships between evolutionary models that do, and those that donot, explicitly recognize biological groups as fitness-bearing entities.We show a fundamental set (...) of mathematical equivalences between these twokinds of models, one of which applies a form of multi-level selectiontheory and the other being a form of ``individualism.'' However, we alsoargue that each type of model can have heuristic advantages over theother. Indeed, it can be positively useful to engage in a kind ofback-and-forth switching between two different perspectives on theevolutionary role of groups. So the position we defend is a``gestalt-switching pluralism.''. (shrink)

The emergence of individuality during the evolutionary transition from single cells to multicellularity poses a range of problems. A key issue is how variation in lower‐level individuals generates a corporate (collective) entity with Darwinian characteristics. Of central importance to this process is the evolution of a means of collective reproduction, however, the evolution of a means of collective reproduction is not a trivial issue, requiring careful consideration of mechanistic details. Calling upon observations from experiments, we draw attention to proto‐life cycles (...) that emerge via unconventional routes and that transition, in single steps, individuality to higher levels. One such life cycle arises from conflicts among levels of selection and invokes cheats as a primitive germ line: it lays the foundation for collective reproduction, the basis of a self‐policing system, the selective environment for the emergence of development, and hints at a plausible origin for a soma/germ line distinction.

Formal methods developed for modeling levels of selection problems have recently been applied to the investigation of major evolutionary transitions. We discuss two new tools of this kind. First, the ‘near-variant test’ can be used to compare the causal adequacy of predictively equivalent representations. Second, ‘state-variable gestalt-switching’ can be used to gain a useful dual perspective on evolutionary processes that involve both higher and lower level populations.

A model of “ephemeral” population structure is presented that applies not only to biological systems in which discrete groups form but also to networks without group boundaries. The evolution of altruistic behaviors is discussed. Nonrandom interaction and nonlinear fitness structures are modeled; together, these factors can produce stable polymorphisms of altruistic and selfish types, as well as bistability. Empirical applications of the model may be found in microbes, marine invertebrates, annual plants, and other organisms.

Wright’s “adaptive landscape” has been influential in evolutionary thinking but controversial, especially because the landscape that organisms encounter is altered by the evolutionary process itsel...

We have two main objections to Kerr and Godfrey-Smith's (2002) meticulous analysis. First, they misunderstand the position we took in Unto Others – we do not claim that individual-level statements about the evolution of altruism are always unexplanatory and always fail to capture causal relationships. Second, Kerr and Godfrey-Smith characterize the individual and the multi-level perspectives in terms of different sets of parameters. In particular, they do not allow the multi-level perspective to use the individual fitness parameters i (...) and i. We don't see why the multi-level perspective prevents one from thinking in these terms. Kerr and Godfrey-Smith's argument that Uyenoyama and Feldman's (1980, 1992) definition of altruism belongs more to the individualist perspective than it does to the multi-level perspective is an artifact of their choice of parameters; the same point applies to their argument about the individualism inherent in the idea of Class I and Class II fitness structures.

This guide to the most interesting work that has recently appeared on Aquinas reflects the revival of interest in his work.

Why do relationships of friendship and love support partiality, but not relationships of hatred or commitments of racism? Where does partiality end and why? I take the intuitive starting point that important cases of partiality are meaningful. I develop a view whereby meaning is understood in terms of transcending self-limitations in order to connect with things of external value. I then show how this view can be used to distinguish central cases of legitimate partiality from cases of illegitimate partiality and (...) how it puts pressure on the traditional way of thinking about partiality.

Fergus Kerr's study - which is derived from his highly-regarded Stanton Lectures, delivered in the University of Cambridge in 1994/5 - focuses on the more or less obvious theological commitments of several much-discussed contemporary philosophers. By so doing, the author daringly extends the agenda of what is usually considered to be 'philosophy of religion.'. The ramifications of his study are extensive: even if philosophy is not at bottom theology, as von Balthasar once claimed, the theological preconceptions in much modern (...) philosophy would seem to deserve considerably more attention than they have received hitherto.

Written by a nurse and a philosopher, Ethics in Nursing blends the concrete detail of recurring problems in nursing practice with the perspectives, methods, and resources of philosophical ethics. It stresses the aspects of the nurses role and relations with others -- physicians, patients, administrators, other nurses -- that give ethical problems in nursing their special focus. Among the issues addressed are deception, parentalism, confidentiality, conscientious refusal, nurse autonomy, compromise, and personal responsibility for institutional and public policy. The third edition (...) has been enlarged with new cases and case discussions related to AIDS and an additional chapter on the expanding scope of nursing ethics as it addresses issues related to scarce resources, cost containment, justice, and the possibilities of health care rationing.

This is the first book to explore the role of quotation in modern Jewish thought. It shows how quotation is the binding tissue that links language and thought, modernity and tradition, religion and secularism as a way of being in the world.

We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their interactions with the receptor site. But, naturally occurring smells are parsed from gaseous odor plumes. To give a comprehensive account of the nature of odors the chemosciences must account for these large distributed entities as well. We offer a focused review of (...) what is known about the perception of odor plumes for olfactory navigation and tracking, which we then connect to what is known about the role odorants play as properties of the plume in determining odor identity with respect to odor quality. We end by motivating our central claim that more research needs to be conducted on the role that odorants play within the odor plume in determining odor identity. (shrink)

Thomas Aquinas is one of the giants of medieval philosophy, a thinker who had--and who still has--a profound influence on Western thought.

Objective: To examine lay persons’ ability to identify methods of random allocation and their acceptability of using methods of random allocation in a clinical trial context.Design: Leaflets containing hypothetical medical, non-medical, and clinical trial scenarios involving random allocation, using material from guidelines for trial information leaflets.Setting and participants: Adults attending further education colleges , covering a wide range of ages, occupations, and levels of education.Main measures: Judgements of whether each of five methods of allocation to two groups was random in (...) a medical or non-medical scenario. Judgements of whether these allocation methods were acceptable in a randomised clinical trial scenario, with or without a scientific justification for randomisation.Results: The majority of our group of participants judged correctly that allowing people their preference was not random, and that the following were random: using a computer with no information about the individual , tossing a coin, drawing a name out of a hat. Judgements were split over allocating people in turn . Judgements were no different in medical and non-medical scenarios. Few of the correctly identified random methods were judged to be acceptable in a clinical trial scenario. Inclusion of a scientific justification for randomising significantly increased the acceptability of only one random method: allocation by computer.Conclusions: Current UK guidelines’ recommended description of random allocation by computer seems warranted. However, while potential trial participants may understand what random allocation means, they may find it unacceptable unless offered an acceptable justification for its use. (shrink)

The right temporo-parietal junction (rTPJ) has been associated with two apparently disparate functional roles: in attention and in social cognition. According to one account, the rTPJ initiates a “circuit-breaking” signal that interrupts ongoing attentional processes, effectively reorienting attention. It is argued this primary function of the rTPJ has been extended beyond attention, through a process of evolutionarily cooption, to play a role in social cognition. We propose an alternative account, according to which the capacity for social cognition depends on a (...) network which is both distinct from and in tension with brain areas involved in focused attention and target detection: the default mode network. Theory characterizing the rTPJ based on the area’s purported role in reorienting may be falsely guided by the co-occurrence of two distinct effects in contiguous regions: activation of the supramarginal gyrus (SMG), associated with its functional role in target detection; and the transient release, during spatial reorienting, of suppression of the angular gyrus (AG) associated with focused attention. Findings based on meta-analysis and resting functional connectivity are presented which support this alternative account. We find distinct regions, possessing anti-correlated patterns of resting connectivity, associated with social reasoning (AG) and target detection (SMG) at the rTPJ. The locus for reorienting was spatially intermediate between the AG and SMG and showed a pattern of connectivity with similarities to social reasoning and target detection seeds. These findings highlight a general methodological concern for brain imaging. Given evidence that certain tasks not only activate some areas but also suppress activity in other areas, it is suggested that researchers need to distinguish two distinct putative mechanisms, either of which may produce an increase in activity in a brain area: functional engagement in the task versus release of suppression.

Thinking is a dynamic process resulting from practices of integration. Thought encounters in openness, wonder, receptivity, and contemplation confer upon us intellectual work that is uniquely our own. Digital patterns, however, distract us from these creative encounters. Our intellectual searching is weakened and fragmented by frenetic consumption of information. We miss out on reason's innate pull toward integration and concrete reality. This book is an invitation to enter into openness, wonder, receptivity, and contemplation with deeper understanding and intentionality. We can (...) do this by considering exemplars, persons who lived out the integrity of their hard-won beliefs, such as Thomas Merton, Eva Saulitis, Malcom X and St. Anselm. Each process of integration is applied also, so that practical knowledge and practice become a way into this intellectual restoration. We need deeper knowledge won in the slow orbit of encounters. Encounters in thought are precisely what each generation needs to apprehend the cosmos, nature, authority, truth, and moral action. Responsibility to this ecologic age requires a reform of reason; this book is just one attempt to convey a way toward this restoration. (shrink)

Evidential Decision Theory and Causal Decision Theory are the leading contenders as theories of rational action, but both face counterexamples. We present some new counterexamples, including one in which the optimal action is causally dominated. We also present a novel decision theory, Functional Decision Theory, which simultaneously solves both sets of counterexamples. Instead of considering which physical action of theirs would give rise to the best outcomes, FDT agents consider which output of their decision function would give rise to the (...) best outcome. This theory relies on a notion of subjunctive dependence, where multiple implementations of the same mathematical function are considered to have identical results for logical rather than causal reasons. Taking these subjunctive dependencies into account allows FDT agents to outperform CDT and EDT agents in, for example, the presence of accurate predictors. (shrink)

Sells encourages a radical departure from the usual introspection and self-centeredness of psychology in our time. By placing style first, Sells argues that we must turn our eyes and minds outward to the greater world. Emphasizing beauty over emotion and appreciation over feeling, he attempts to break the stranglehold of the self so as to reconstitute our proper place among the many things of the world.

Dans ce long inédit, Benjamin Fondane révèle les implications philosophiques révolutionnaires qui découlent des travaux de Lévy-Bruhl (1857-1939) sur la mentalité primitive. En mettant à jour les mécanismes d'une logique différente, Lévy-Bruhl fait voler en éclat l'universalité de la logique d'Aristote sur laquelle repose notre pensée occidentale. Dès lors cette logique n'est rien d'autre qu'une arme politique qui fonde l'hégémonie de la rationalité.0La démonstration de Fondane est implacable et bouleverse notre conception de la philosophie. Il nous incite à reconsidérer (...) nos manières de penser et de vivre sous la contrainte de la raison, faisant écho à une tradition non aristotélicienne qu'incarnent des penseurs comme Michelstaedter, Lukasiewicz ou Alfred Korzybski.

This article argues that teachers of environmental ethics must more aggressively entertain questions of private property in their work and in their teaching. To make this case, it first introduces the three primary positions on property: occupation arguments, labor theory of value arguments, and efficiency arguments. It then contextualizes these arguments in light of the contemporary U.S. wise-use movement, in an attempt to make sense of the concerns that motivate wise-use activists, and also to demonstrate how intrinsic value arguments miss (...) the mark. Finally, it offers some suggestions about further directions for environmental ethics, reasoning that there is a good deal of headway to be gained for environmental ethics by accepting that nature can be owned as property, but nevertheless engaging the idea of private property critically.

Positive education seeks to enhance wellbeing in schools by establishing a culture where success is measured in terms of happiness. This goal aligns well with Dewey’s educational philosophy, which espouses the importance of a positive school experience in the nurturing of good citizenship and the creation of a harmonious community. Dewey’s ideas and those expressed within the field of positive education, however, diverge on some aspects of their approach to education and, importantly, in their perspective on the role of philosophy (...) in science. This thesis explores the possibility of a Deweyan contribution to positive education and advances the argument that embracing Dewey’s ethics and epistemology will augment efforts to create a culture of wellbeing in schools. Specifically, this thesis argues that Dewey’s work may contribute a perspective on the complementary role of philosophy and science; suggest an experiential pedagogy that contends with the nature of subjective experience; contribute a social focus that prioritizes the common good; and provide a unified philosophical stance on the purpose of schooling. These contributions may, however modestly, address concerns expressed by writers from within and outside of positive psychology about challenges such as a need for a more philosophical approach, the effects of psychology in education, the difficulties with avoiding normative content in order to remain scientific, the problem of subjective experience, the perceived focus on individualism, and the implication that positive psychology may be a fad. Ultimately, by creating a dialogue between positive education and the work of Dewey, this thesis seeks to elicit thinking about the possibility of a Deweyan contribution to both the theory and practice of positive education.

La Conscience malheureuse est un ouvrage majeur de la philosophie existentielle des années trente. Jeune poète et critique roumain expatrié en France en 1923, Benjamin Fondane (1898-1944) fait partie de ces auteurs hantés par l'absence de Dieu dans la culture rationaliste moderne marquée par le positivisme. D'abord proche de l'esprit subversif du dadaïsme, il identifie rapidement sa révolte par l'absurde à la démarche ironique et irrationaliste du philosophe russe émigré en France Léon Chestov. C'est l'adhésion sans conditions à sa (...) philosophie existentielle à partir de 1929 qui lui permet de déconstruire la tradition du logos issue d'Athènes. Il ne cessera dès lors de dénoncer un conflit profond entre le " réel " construit par la culture rationaliste et l'existant singulier, entre le savoir et le " non-voir " des poètes et de certains mystiques, entre Athènes et Jérusalem: ce divorce intime, c'est celui de la " conscience malheureuse ".

The book contends that contrary to accepted interpretation, moral intuition, rather than any other form of reasoning, least of all formal logic, is the moral method found in the ethics of Aristotle, Aquinas, Kant and Dewey - the first four chapters of the book. These four thinkers represent a dialectical selection of ethical relativism and absolutism as well as a chronological succession from ancient to contemporary thought. The fifth and concluding chapter is a major presentation of the author's thesis on (...) moral intuition as the exact antidote against the dilemma ethics approach, which is widely used today with rapidly diminishing effect and interest. This chapter is a detailed illustration of how moral intuition works out concretely in the lived world. It stresses the unity of moral experience even as this is clouded over by our relatively fewer, but overdramatized, confrontations on some moral issues. (shrink)

Given that as much as half of human thought arises in a stimulus independent fashion, it would seem unlikely that such thoughts would play no functional role in our lives. However, evidence linking the mind-wandering state to performance decrement has led to the notion that mind-wandering primarily represents a form of cognitive failure. Based on previous work showing a prospective bias to mind-wandering, the current study explores the hypothesis that one potential function of spontaneous thought is to plan and anticipate (...) personally relevant future goals, a process referred to as autobiographical planning. The results confirm that the content of mind-wandering is predominantly future-focused, demonstrate that individuals with high working memory capacity are more likely to engage in prospective mind-wandering, and show that prospective mind-wandering frequently involves autobiographical planning. Together this evidence suggests that mind-wandering can enable prospective cognitive operations that are likely to be useful to the individual as they navigate through their daily lives. (shrink)
