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.

Many compelling examples have recently been provided in which people can achieve impressive epistemic success, e.g. draw highly accurate inferences, by using simple heuristics and very little information. This is possible by taking advantage of the features of the environment. The examples suggest an easy and appealing naturalization of rationality: on the one hand, people clearly can apply simple heuristics, and on the other hand, they intuitively ought do so when this brings them high accuracy at little cost.. The ‘ought-can’ (...) principle is satisfied, and rationality is meaningfully normative. We show, however, that this naturalization program is endangered by a computational wrinkle in the adaptation process taken to be responsible for this heuristics-based (‘ecological’) rationality: for the adaptation process to guarantee even minimal rationality, it requires astronomical computational resources, making the problem intractable. We consider various plausible auxiliary assumptions in attempt to remove this obstacle, and show that they do not succeed; intractability is a robust property of adaptation. We discuss the implications of our findings for the project of naturalizing rationality. (shrink)

The words "violence" and "nonviolence" are increasingly misleading translations for the Sanskrit words hiṃsā and ahiṃsā -- which were used by Gandhi as the basis for his philosophy of satyāgraha. I argue for re-reading hiṃsā as “maleficence” and ahiṃsā as “beneficence.” These two more mind-referring English words – associated with religiously contextualized discourse of the past -- capture the primacy of intention implied by Gandhi’s core principles, better than “violence” and “nonviolence” do. Reflecting a political turn in moral accountability detectable (...) through linguistic data, both the scope and the usage of the word “violence” have expanded dramatically. The expanded scope of “violence” reflects greater consciousness of the various forms that serious harm can take, but also makes it harder to convincingly characterize people and actions as “nonviolent.” New translations could clarify the distinction between hiṃsā and ahiṃsā, and thereby prevent some misunderstandings of Gandhi. Training in beneficence would reflect Gandhi’s psychological path to reducing avoidable harm: detachment from the ego, learning to love universally, and seeking truth by experiment. (shrink)

Herodotus tells us in book vii, ch. 220, that the Pythian priestess gave the Spartans a warning couched in hexameters, of which the second line begins ἢ μγα στυ ρικυδς. To this text the admirable commentary of How and Wells takes exception in the following note: ‘The synizesis στυ ρικυδς is intolerable. Read δμ' ρικυδς, στυ being a gloss, H. Richards, Cl. Rev. xix. 345.’ Doubtless this union of vowels is harder than that of υω in ρινων or in γενων (...) and δυωδεκμηνον, accepted by Christ in his edition of Pindar . Let us grant that from the point of view of elegance it is even intolerable; the question still remains, should the line be altered? (shrink)

This book is the second volume of a critical edition of the writings of Thomas Reid, an edition that will include many of his manuscript remains as well as his previously published works. These volumes are intended to displace the heretofore standard 8th edition of Reid’s works edited by Sir William Hamilton. Hamilton’s edition is marred by his numerous, often intrusive, and obtuse footnotes. Reid’s spelling and punctuation were also sometimes “corrected” by Hamilton, so his edition does not present a (...) fully accurate version of the original editions whose publication was superintended by Reid. The type in the Hamilton edition is also archaic and very small, making reading the text excessively difficult. The present and subsequent volumes are intended to present canonical texts free of the flaws in the Hamilton text. This volume succeeds admirably in that project. (shrink)

Blair proposes that fluid intelligence, working memory, and executive function form a unitary construct: fluid cognition. Recently, our group has utilized a combined correlational–experimental cognitive neuroscience approach, which we argue is beneficial for investigating relationships among these individual differences in terms of neural mechanisms underlying them. Our data do not completely support Blair's strong position. (Published Online April 5 2006).

Schmitt recognized that research is needed to identify other factors associated with sex ratio and with sociosexuality that may explain cross-cultural variation in sexual behavior. One such factor may be the risk of sperm competition. Sperm competition theory may lead us to a more complete explanation of cultural variation in sexual behavior.

Polls suggest up to twenty percent of Americans describe their beliefs as 'libertarian', but libertarians are often derided as heartless Social Darwinists or naïve idealists. This illuminating handbook brings together scholars from a range of fields and political perspectives to consider how classical liberal principles can help us understand and potentially address a variety of pressing social problems including immigration, climate change, the growth of the prison population, and a host of others. Anyone interested in political theory or practical law (...) and politics will find this book an essential resource for understanding this major strand of American politics. (shrink)

The phenomenon of globalization is widely recognized as the dominant rubric for describing life in the twenty-first century, yet fierce debates are currently being waged over its definition and beneficence to society. This essay offers a typology of four competing globalization theories— neoliberal, development, earthist, and postcolonial—that currently dominate globalization discourses and briefly sketches the constituencies, ideological underpinnings, and moral vision of each as background. It then critiques these theories using a set of normative criteria offered by the author. These (...) criteria are framed to answer the question "What constitutes the good life?" and are rooted in a feminist, Christian ethical analysis of globalization. They delineate a democratized understanding of power as the context of moral agency, define humanity's purpose as caring for the planet, and establish that human flourishing is evidenced by the social well-being of people. The paper concludes by suggesting some pathways of transformation that build on these criteria. (shrink)

Investigation of “out-of-body experiences” has implications for understanding both normal bodily-self integration and its vulnerabilities. Beyond reported associations between OBEs and specific brain regions, however, there have been few investigations of neurochemical systems relevant to OBEs. Ketamine, a drug used recreationally to achieve dissociative experiences, provides a real-world paradigm for investigating neurochemical effects. We investigate the strength of the association of OBEs and ketamine use relative to other common drugs of abuse. Self-report data from an online survey indicate that both (...) lifetime frequency of ketamine use and OBEs during ketamine intoxication were more strongly related to the frequency of OBEs and related phenomena than other drugs. Moreover, the apparent effects of other drugs could largely be explained by associated ketamine use. The present results, consistent with the role of NMDA receptors in OBEs, should encourage future studies of the role of neurochemical systems in OBEs. (shrink)

ABSTRACT This paper responds to Vanessa Andreotti’s keynote address. In it, I draw out some educational implications of facing the everyday denials of the climate emergency. In particular, I mobilise Bruno Latour’s phrase ‘landing on Earth’ to indicate that the very terms through which we understand education, particularly as it relates to the future, require a profound shift.

Alain Badiou argues in “Rancière and Apolitics” that Rancière has appropriated his central idea of equality from Badiou’s own work. We argue that Badiou’s characterisation of Rancière’s project is correct, but that his self-characterisation is mistaken. What Badiou’s ontology of events opens out onto is not necessarily equality, but instead universality. Equality is only one form of universality, but there is nothing in Badiou’s thought that prohibits the (multiple) universality he positsfrom being hierarchical. In the end, then, Badiou’s thought moves (...) in a Maoist direction while Rancière’s in an anarchist one. (shrink)

Michael Bergmann seeks to motivate his externalist, proper function theory of epistemic justification by providing three objections to the mentalism and mentalist evidentialism characteristic of nonexternalists such as Richard Feldman and Earl Conee. Bergmann argues that (i) mentalism is committed to the false thesis that justification depends on mental states; (ii) mentalism is committed to the false thesis that the epistemic fittingness of an epistemic input to a belief-forming process must be due to an essential feature of that input, and, (...) relatedly, that mentalist evidentialism is committed to the false thesis that the epistemic fittingness of doxastic response B to evidence E is an essential property of B–E; and (iii) mentalist evidentialism is “unmotivated”. I object to each argument. The argument for (i) begs the question. The argument for (ii) suffers from the fact that mentalist evidentialists are not committed to the consequences claimed for them; nevertheless, I show that there is, in the neighborhood, a substantive dispute concerning the nature of doxastic epistemic fittingness. That dispute involves what I call “Necessary Fittingness”, the view that, necessarily, exactly one (at most) doxastic attitude ( belief , or disbelief , or suspension of judgment ) toward a proposition is epistemically fitting with respect to a person’s total evidence at any time. Reflection on my super-blooper epistemic design counterexamples to Bergmann’s proper function theory reveals both the plausibility of Necessary Fittingness and a good reason to deny (iii). Mentalist evidentialism is thus vindicated against the objections. (shrink)

We describe a recipe for generating normal ideals on successors of singular cardinals. We show that these ideals are related to many weakenings of □ that have appeared in the literature. Our main purpose, however, is to provide an organized list of open questions related to these ideals.

Abstract:Unable to produce scales of one-to-one in places or spaces, people interact as they develop common representations, actions, and objects. In places, they can point to connect representations and objects. Places may be small spaces, but spaces can contain places and even more variations. Unable to name each variation, actors and analysts create abstractions. They might use a part to represent the whole, with miles of track for railroads, kilowatt-hours for electric power, and barrels of oil for energy. Some treat (...) their representations as hegemonic, even true. However, dealing with social and material variations, actors and analysts represent, build, maintain, and repair combinations of cultures, economies, governments, and materials. Thus, railroads and power systems, like other technologies and infrastructures, do not design, build, or repair themselves. To resolve problems, people with relevant skillsets interact in places to create common representations, actions, and objects tying themselves and others together in spaces. (shrink)

This paper first traces the general influence of Ernest Barker's undergraduate training in Oxford's School of Literae Humaniores on his later work on ancient political thought, and in particular shows how Idealism conditioned his view that the major ancient texts were perennially relevant and also applicable to practical affairs. The second part of the paper is based on a letter that Barker wrote to E.R. Dodds in 1953 critical of Dodds's negative perspective in The Greeks and the Irrational on the (...) religious culture of the early centuries of the Roman Empire. This document offers a revealing insight into the gulf between Barker's Christian values and optimistic view of the evolution of the classical tradition and Dodds's pessimistic secularism, which had its theoretical basis in ideas drawn from social psychology which Barker had always despised.

This paper is a response to Troy Richardson’s Terence McLaughlin’s Lecture. In it, I discuss how Richardson provides a unique reading of relationality, drawing together technology studies, Indigenous Education and feminist philosophy of education. Seeking to walk with key ideas he develops, this response also points to a possible limitation in seeing Noddings ethic of care as part of a feminist relational ontology that can help inform new ways of understanding ‘machine learning’. In particular, I introduce the notion of worlding (...) as a way of complementing Richardson’s reading of relationality – a notion that has profound implications for pedagogical practice. (shrink)

For Permissions, please email: [email protected] largely upon a series of previously published papers, this book tackles a diverse range of topics – including the nature of practical reasons, impartiality, personhood, the phenomenal content of moral experience, and the notions of glory and beauty in ethics – that are unified by an overarching commitment to an anti-systematic approach to normative ethics. The presiding influences (...) here are Bernard Williams and Wittgenstein, and, in certain respects, Kant, and the overall view is a kind of realist virtue ethics. Chappell’s method is frequently broad and illustrative, rather than detailed and argumentative, and rich in theological and literary allusions. The price to be paid for the considerable insight and breadth is a lack of neatness and clarity in some of the discussion, but Chappell’s main... (shrink)
