Foraging‐ and feeding‐related behaviors across eumetazoans share similar molecular mechanisms, suggesting the early evolution of an optimal foraging behavior called area‐restricted search (ARS), involving mechanisms of dopamine and glutamate in the modulation of behavioral focus. Similar mechanisms in the vertebrate basal ganglia control motor behavior and cognition and reveal an evolutionary progression toward increasing internal connections between prefrontal cortex and striatum in moving from amphibian to primate. The basal ganglia in higher vertebrates show the ability to transfer dopaminergic activity from (...) unconditioned stimuli to conditioned stimuli. The evolutionary role of dopamine in the modulation of goal‐directed behavior and cognition is further supported by pathologies of human goal‐directed cognition, which have motor and cognitive dysfunction and organize themselves, with respect to dopaminergic activity, along the gradient described by ARS, from perseverative to unfocused. The evidence strongly supports the evolution of goal‐directed cognition out of mechanisms initially in control of spatial foraging but, through increasing cortical connections, eventually used to forage for information.

When searching for concepts in memory—as in the verbal fluency task of naming all the animals one can think of—people appear to explore internal mental representations in much the same way that animals forage in physical space: searching locally within patches of information before transitioning globally between patches. However, the definition of the patches being searched in mental space is not well specified. Do we search by activating explicit predefined categories and recall items from within that category, or do we (...) activate and recall a connected sequence of individual items without using categorical information, with each item recalled leading to the retrieval of an associated item in a stream, or both? Using semantic representations in a search of associative memory framework and data from the animal fluency task, we tested competing hypotheses based on associative and categorical search models. Associative, but not categorical, patch transitions took longer to make than position-matched productions, suggesting that categorical transitions were not true transitions. There was also clear evidence of associative search even within categorical patch boundaries. Furthermore, most individuals' behavior was best explained by an associative search model without the addition of categorical information. Thus, our results support a search process that does not use categorical information, but for which patch boundaries shift with each recall and local search is well described by a random walk in semantic space, with switches to new regions of the semantic space when the current region is depleted.

The need for a theoretical grounding of the human-animal relationship is addressed from the perspective of the motivational bases of attitudes toward animals. Building on recent developments in attitude theory, and integrating themes from the historical and cultural background to Western attitudes, a model is developed that proposes three fundamental motivational bases, where responses to animals depend on instrumental self interest, empathylidentification, or people's beliefs and values about the nature and status of animals. Initial empirical studies using the model revealed (...) reduced instrumentality, heightened empathy, and strong commitment to a value perspective endorsing equal status for humans and animals among animal rights supporters. Farmers exhibited an opposite pattern, and supported the dominant status of humans. The urban public evidenced moderate levels of instrumentality and empathy, and a neutral value position with some individuals exhibiting considerable ambivalence . Gender differences on instrumentality and empathy , were less evident for values, and were confined to female and male farmers. Directions for future research are discussed, as is the practical value of this approach. (shrink)

According to the doctrine of double effect(DDE), there is a morally significantdifference between harm that is intended andharm that is merely foreseen and not intended.It is not difficult to explain why it is bad tointend harm as an end (you have a ``badattitude'' toward that harm) but it is hard toexplain why it is bad to intend harm as a meansto some good end. If you intend harm as a meansto some good end, you need not have a ``badattitude'' toward (...) it. I distinguish two ways inwhich you can treat something that is yourchosen means to your ends. You can pursue yourends directly, and treat X as a mere means thatyou pursue for the sake of your end. Or you canpursue your ends indirectly, and treat X as a``plan-relative end'' that you pursue for its ownsake. I argue that much of the time we pursueour ends indirectly, and treat our means asplan-relative ends. There are significantanalogies between intending harm as an end, andintending harm as a plan-relative end. So,under certain circumstances, it is morallyworse to intend harm as a means or an end thanto foresee bringing about the same amount of harm. (shrink)

The most prominent recent interpretations of Kantian ethics place rational nature at the centre of the theory: I must respect rational nature, whether in myself or in others, because rational nature has a special status as the source of all other values. It is not obvious what it is for something to be the source of value, nor whether rational nature could play this role, but until these issues are settled the coherence of Kantian ethics is in question. In this (...) article I offer an explanation of what it is for rational nature to be the source of value, I show that this claim is an important element of Kant's moral theory, and I defend this conception of value.

The question of domain-specific versus domain-general processing is an ongoing source of inquiry surrounding cognitive control. Using a comparative evolutionary approach, Stout (2010) proposed two components of cognitive control: coordinating hierarchical action plans and social cognition. This article reports additional molecular and experimental evidence supporting a domain-general attentional process coordinating hierarchical action plans, with the earliest such control processing originating in the capacity of dynamic foraging behaviors—predating the vertebrate-invertebrate divergence (c. 700 million years ago). Further discussion addresses evidence required for (...) additional, domain-specific, cognitive control processes, noting that proposed social processes may simply provide emotionally valenced representational information to the above hierarchical process.

Sidgwick argued that utilitarianism was not rationally required because it could not be shown that a utilitarian theory of practical reason was better justified than a rival egoist theory of practical reason: there is a 'dualism of practical reason' between utilitarianism and egoism. In this paper, it is demonstrated that the dualism argument also applies to Kant's moral theory, the moral law. A prudential theory that is parallel to the moral law is devised, and it is argued that the moral (...) law is no better justified than this prudential theory. So the moral law is not rationally required. It is suggested that the dualism argument is a completely general argument that ethics cannot be rationally required. (shrink)

The unit of metaphor isn’t always a complete sentence; often it is a single word or phrase. In such a case, the word or phrase in question makes a nonstandard, metaphorically determined contribution to the propositional content of the sentence in which it appears, a content whose other ingredients are determined in routine ways by routine recursive procedures of truth-conditional semantics. In this respect, metaphor belongs to semantics. In other respects, it doesn’t belong to semantics at all. To identify what (...) Yeats contributed to the content of his own sentence when he wrote.

In the current philosophical literature on trustworthiness, two claims are very widely accepted, first that trustworthiness is a kind of reliability and secondly, that trustworthiness is not a virtue. Both claims are made, for instance, in Hawley's recent highly influential account of trustworthiness. I argue that both are mistaken. I develop and defend a new account of trustworthiness as responsibility, contrasting it with reliability and obligation accounts of trustworthiness. I argue that trustworthiness as responsibility is very plausibly a kind of (...) moral virtue. (shrink)

Jennifer Lackey argues that knowing that p is not sufficient for being epistemically properly positioned to assert that p. Where that knowledge is entirely second-hand and the subject is an expert, the subject is not properly positioned to make such an assertion—since experts are held to higher epistemic standards. We reject Lackey’s argument. In particular, we argue that the division of labour in science makes isolated, second-hand assertions by experts both inevitable and frequent.

Interest is growing in the relocalization of staple crops, including wheat, in western Washington (WWA), a nontraditional wheat-growing area. Commercial bakers are potentially important food chain intermediaries in the case of relocalized wheat production. We conducted a mail survey of commercial bakers in WWA to assess their interest in sourcing wheat/flour from WWA, identify the characteristics of bakeries most likely to purchase wheat/flour from WWA, understand the factors important to bakers in purchasing regionally produced wheat/flour, and identify perceived barriers to (...) making such purchases. Sixty-one percent of survey respondents were interested in purchasing WWA wheat/flour. Bakers who used retail strategies to market their products were more likely to be interested in WWA wheat/flour compared to those not using retail methods. Bakers’ current purchases of Washington wheat/flour were not related to their interest in purchasing WWA flour. The most important factors bakers would consider in purchasing regionally produced wheat/flour were consistency of flour quality, quality of flour, and reliability of supply. Cost was the most frequently mentioned barrier to the purchase of regionally produced wheat/flour. Our results are relevant for other areas attempting to reconnect grain producers, commercial bakers, and consumers in mutually beneficial ways. (shrink)

This essay on pragmatist aesthetics explains how imagination extends the environment into the possible. While there is no lack of pragmatic theories claiming that imagination extends the environment, few explain how in the scholarship on John Dewey. After discussing the incompleteness of Mark Johnson's scholarship on this question, I expand upon Thomas Alexander's work to construct a Deweyan-pragmatic view of the dynamic structure of imaginative function that emphasizes continuity, temporality, and the emergence of meaning. Pragmatist scholars must address the question (...) of how, else they are blind to the limitations of imagination while making promises on its transformative power. Though the present work is rooted in historic scholarship, it promises to flower in contemporary debates in aesthetics, realist phenomenology, and reconciling naturalism and phenomenology. (shrink)

"By comparing the Epistle section by section with relevant passages from the Gospels, the author demonstrates the contiinuity of Paul's preaching with the teaching of Christ during his jministry, and releases for the reader the power of the Spirit which is pent up in the apostle's carefully chosen words. The "Reflections" add up to a complete commentary on the Epistle. But this is more than a commentary: it places the Epistle immediately at the service of the preacher and teacher. The (...) reader is not left to make for himself the (often difficult) transition from the deskk to pulpit." - back cover. (shrink)

The need to maintain the public trust in the integrity of the accounting profession has led to increased interest in research that examines the moral reasoning abilities (MRA) of Certified Public Accountants (CPAs). This study examines the MRA of CPAs practicing in small firms or as sole practitioners and the factors that affect MRA throughout their working careers.The results indicate that small-firm accounting practitioners exhibit lower MRA than expected for professionals and that age, gender and socio-political beliefs affect the moral (...) reasoning abilities of small-firm practitioners. We also find that completion of an ethics course in college has a positive impact on MRA. Also, the survey respondents indicate overwhelming support for including ethics courses within the business curriculum. Finally, the fact that those accountants with the lowest MRA are the least supportive of ethical training may indicate the need for mandatory, rather than optional, training in ethics both in university and Continuing Professional Education courses.

Hans Lipps compares pragmatism (William James and John Dewey) existentialism (Friedrich Nietzsche, Soren Kierkegaard, and Martin Heidegger) in this 1936 article translated from French. He claims that they aim at the same goals, e.g., a return to lived experience and a rejection of the Cartesian legacy in philosophy. While summarizing the commonalities of each, he engages in a polemic against philosophy then that remains relevant now into the next century.

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade‐offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that (...) a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold‐based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non‐decreasing thresholds. Decreasing threshold strategies that “front‐load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration.
