In this study, we used a word search puzzle paradigm to investigate age differences in the rate of information gain and the cues used to make patch-departure decisions in information foraging. The likelihood of patch departure increased as the profitability of the patch decreased generally. Both younger and older adults persisted past the point of optimality as defined by the marginal value theorem, which assumes perfect knowledge of the foraging ecology. Nevertheless, there was evidence that adults were rational in terms (...) of being sensitive to the change in RG for making the patch-departure decisions. However, given the limitations in cognitive resources and knowledge about the ecology, the estimation of RG may not be accurate. Younger adults were more likely to leave the puzzle as the long-term RG incrementally decreased, whereas older adults were more likely to leave the puzzle as the local RG decreased. However, older adults with better executive control were more likely to adjust their likelihood of patch-departure decisions to the long-term change in RG. Thus, age-dependent reliance on the long-term or local change in RG to make patch-departure decisions might be due to individual differences in executive control. (shrink)

Politics, Philosophy & Economics, Volume 21, Issue 4, Page 415-436, November 2022. Recent debates over ideal theory have reinvigorated interest in the question of anarchy. Would a perfectly just society need—or even permit—a state? Ideal anarchists such as Jason Brennan, G.A. Cohen, Christopher Freiman, and Jacob Levy argue that strict compliance with justice obviates the need for a state. Ideal statists such as David Estlund, Gregory Kavka, and John Rawls think that coercive political institutions serve indispensable functions even in (...) ideal conditions. This paper defends ideal anarchism. Our argument begins by describing a camping trip inspired by Cohen that illustrates why an anarchist form of cooperation is more intrinsically desirable than the statist alternative. After detailing Rawls's ideal theory and Estlund's “nonconcessive” moral theory, we argue—contrary to Rawls, Estlund, and Kavka—that large-scale societies without moral imperfection do not need a state.

G.A. Cohen famously claims that egalitarians shouldn’t be so rich. If you possess excess income and there is little chance that the state will redistribute it to the poor, you are obligated to donate it yourself. We argue that this conclusion is correct, but that the case against the rich egalitarian is significantly stronger than the one Cohen offers. In particular, the standard arguments against donating one’s excess income face two critical, unrecognized problems. First, we show that these arguments imply (...) that citizens have no duty to further egalitarian political institutions—a conclusion that Cohen’s Rawlsian opponents cannot abide. Second, these arguments yield unacceptable implications for other questions of justice. We conclude that even moderately rich egalitarians are obligated to donate their excess income. (shrink)

The ‘community principle’ is crucial to G. A. Cohen’s argument for socialism, because it is the best independent argument he has adduced for his strongly egalitarian conclusions. Cohen argues that even small differences in wealth ought to be prohibited because they bring us out of community with one another. In this paper, I show that his underlying premises lead to some repugnant conclusions, and thus should be rejected. If Cohen is right that even small differences in wealth can upset community, (...) then, by the very psychological mechanisms he identifies, we should think that other differences, such as differences in religion, conceptions of the good, race, or taste, should also upset community. Cohen is thus caught in a trap: the more strongly egalitarian his community principle is, the more it not only prohibits differences of wealth, but diversity of any kind, including the forms of diversity we should celebrate rather than reject.

In Why Not Socialism ?, G. A. Cohen argues that market society and capitalism are intrinsically repugnant. He asks us to imagine an ideal camping trip, which becomes increasing repugnant as it shifts from living by socialist to capitalist principles. In this paper, I expose the limits of this style of argument by making a parallel argument, which shows how an ideal anarchist camping trip becomes increasingly repugnant as the campsite turns from anarchism to democracy. When we see why this (...) style of argument fails to generate interesting objections to democracy, we then see why it also fails to generate interesting objections to market society. (shrink)

G. A. Cohen and David Estlund have recently defended utopophilia against utopophobia. They argue we should not dumb down the requirements of ethics or justice to accommodate people’s motivational failings. The fact that certain people predictably will not do the right thing does not imply they are unable to do so, or that they are not obligated to do so. Utopophiles often defend left-wing ideas; for instance, Cohen argues that people’s unwillingness to do what socialism requires does not imply that (...) socialism is bad, but instead that people are bad. This essay shows that utopophiles must also endorse certain “conservative” conclusions, such as that most poor adults in the developed West are obligated to act more prudently, get jobs, become net taxpayers, avoid having children they cannot afford, and act to avoid needing welfare or assistance.

Pickering & Garrod's (P&G's) call to study language processing in dialogue context is an appealing one. Their interactive alignment model is ambitious, aiming to explain the converging behavior of dialogue partners via both intra- and interpersonal priming. However, they ignore the flexible, partner-specific processing demonstrated by some recent dialogue studies. We discuss implications of these data.

Stephen Hood asks a number of interesting questions about which moral norms govern competition. Pace Hood, I argue that these questions have no bearing on the debate between G. A. Cohen and me, as either one of us could answer those questions any number of ways, without this changing our view on whether a fully just society would be socialist or capitalist.

In this article I examine recent debates surrounding the publication of Daniel J. Goldhagen's controversial book Hitler's Willing Executioners. I do so against the `backdrop' of contention regarding the (historical) centrality of the Nazi Holocaust and the role played by Holocaust Studies - a burgeoning area of academic special interest, involving mainly historians, but also sociologists, theologians and philosophers. In particular I consider the charged disputation(s) which have flowed from Norman G. Finkelstein's critique of Hitler's Willing Executioners and ponder what (...) this tells us about the way in which (political) identity is configured in the post-Holocaust era. In so doing I examine the political investments at stake in these debates and challenge the degree to which academics working within this field have been able to transcend the ideological subject-positions in which they are embedded.

Open peer commentary on the article “Beyond Technocentrism: Supporting Constructionism in the Classroom” by Karen Brennan. Upshot: Brennan describes ways by which teachers can be supported to bypass a technocentric view of learning with technology in the classroom, from a constructionist perspective. She reports on the development of a corresponding model of professional development by describing the elements of the model and its design principles as well as the tensions that arose while trying to support teachers’ explorations and (...) experiences in the classroom. Questions arise about the potential of the model to be exploited to address issues underlying teachers’ professional development in different contexts. (shrink)

Semiotic objections to markets urge us not to place a good on the market because of the message that doing so would send. Brennan and Jaworski reject them on the grounds that either the contingent semiotics of a market can be changed or the weakness of semiotic reasons allows them to be ignored. The scope of their argument neglects the impure semiotic objections that claim that the message a market sends causes, constitutes, or involves a nonsemiotic wrong. These are (...) the most compelling class of semiotic objections and are the kind actually advanced in the literature. Rather than focusing on the necessity or contingency of a market's semiotics, we should instead attend to a semiotic objection's most important feature: its purity or impurity. (shrink)

Explaining Norms is a work in philosophy of social science aspiring to provide an account of norms, their general character, their kinds ðformal, legal, moral, and socialÞ, what they can explain, and what explains their dynamic ðemergence, persistence, and unravelingÞ. The authors engage with various positions in ethics, political philosophy, and ðto some extentÞ the philosophy of law. The discussion is rewarding and inventive—it provides distinctive and intriguing views on several topics ðe.g., on the distinction between moral and social normsÞ. (...) There are a lot of ideas here. Perhaps this is predictable, given that the work is a product of four capable minds. What is surprising is the range of ideas and arguments on which the authors manage to agree and out of which they construct one reasonably cohesive account. Given the wide range of literatures discussed, readers are likely to find much of interest. Not surprisingly, some related literatures do seem to be underplayed—treated in a few footnotes and somewhat by the way, with little development of systematic connections. There are thriving literatures in comparative psychology/ ethology, moral psychology, and cultural anthropology that are devoted to how we humans manage to cooperate and coordinate as we do. While there are footnotes to some of this literature ðsee the index for, e.g., Boyd, Bowles, Camerer, Gintis, and HenrichÞ, many readers would have benefited from a discussion that more fully related the position developed in Explaining Norms to that work in experimental economics and anthropology. Discussing the relationships with work in moral psychology and ethology would also have been appreciated ðHaidt, de Waal, and Tomasello are not mentionedÞ. Still, there is very much to like about what is treated here. The authors seek conceptually individually necessary and jointly sufficient conditions for being a norm. On the account provided, norms are something on the order of normative principles accepted in some group ð3–4Þ. Thus, norms involve some normative principle, possessing “a certain generality of scope and application.” These principles need not be objectively correct or fitting, and they may be objectively “simply awful” ð3Þ. The central questions have to do with what is involved in some group accepting these normative principles. The authors locate their position in two dimensions. (shrink)

the standard reading of plato's Republic is that justice is predicated of the ideal city and of the philosophers, and that all other constitutions, both psychic and political, that are mentioned in the course of the dialogue are in some way or another defective and unjust. A non-standard reading appears to be gaining traction, however. Unorthodox Plato commentators such as Silverman, Jonas, Nakazawa, Braun, and Rowe argue that the ideal city—lovingly named 'Kallipolis'—is not just, that it is merely an improvement (...) upon, but not a complete cure for, the Luxurious City that is described immediately before it.1 If we want to gaze upon a just city, these unorthodox commentators propose, look no farther than the City of...

This article surveys recent feminist contributions to moral philosophy with an emphasis on those works which engage with debates within mainstream ethics. The article begins by examining a tension said to arise from the two criteria a theory must meet if it is to count as feminist moral theory: the women's experience requirement and the feminist conclusion requirement. Subsequent sections deal with feminist relational theories of rights, feminist work on responsibility and feminist contractarian approaches to ethics. A final section looks (...) at the application of some feminist moral theories to the problem of abortion. (shrink)

Attacks on ?closest continuer? and ?best candidate? theories of identity have something correct in them while still failing to discredit the theories they oppose. What follows from Noonan's and Wiggins's objections to such theories is that they need to be so formulated as not to deny the necessity of identity. The best metaphysics for best?candidate theories to adopt is one in which everyday objects are taken to transcend, in a certain sense, their life histories in given worlds. This metaphysics also (...) has the potential for solving problems about contingent identity, transworld identity, and the issue of haecceitism or individual essence. To develop the metaphysics, it is only necessary to follow through the analogy between worlds and times suggested by writers like Plantinga and Schlesinger. (shrink)

Despite the extensiveness of top-down control in his ideal city, Plato takes seriously the idea that the market does not require total regulation via legislation and that participants in the market may be capable of self-regulation. This paper examines the discussion of market regulation in the Republic and argues that the philosopher rulers play a very limited role in regulating market activities. Indeed, they are concerned only with averting excesses of wealth and poverty. The rules and regulations that are foundational (...) to the daily functioning of the market – enforcement of contracts, resolution of disputes, etc. – are endogenous to the market participants themselves. In allowing for this self-regulation, Plato expresses tempered optimism about the market and a profound confidence in his ideal city’s educational program. (shrink)

The second conjunct of the Republic’s account of justice—that justice is “not meddling in the work of another”—has been neglected in Plato literature. This paper argues that the conjunct does more work than merely reiterating the content of the first conjunct—that justice is “doing one’s own work.” I argue that Socrates develops the concept at work in this conjunct from its introduction with the Principle of Specialization in Book II to its final deployment in the finished conception of justice in (...) Book IV. Crucial to that concept’s development is the way in which the notion of “another” comes to refer to members of distinct classes or parts, i.e. takes on an inter-part connotation beyond a mere intra-part connotation. The first conjunct—that justice is “doing one’s own work”—does not connote the same divisions, and so the conjuncts should not be understood as equivalent or mutually entailed. (shrink)

Greek Philosophers of the Hellenistic Age examines an important but frequently neglected group of philosophers writing after Aristotle between the third and first centuries B.C. The work of a distinguished intellectual historian, this book is based on an erudite reading of a vast number of primary sources: the Greek and Latin writings of the philosophers, and the fragments, paraphrases, and testimonies from their lost works. Kristeller explores the thought of Epicurus; Zenon and Cleanthes, the founder of the Stoic school and (...) his successor; Pyrrhon and Arcesilaus, the founder of Skepticism and the philosopher who introduced it into the Platonic Academy; and Chrysippus, the third head of the Stoic school and its most important representative. Other figures include Carneades and Philo of Larissa, the second and third representatives of Skepticism in the Platonic Academy, respectively; Panaetius, the first leader of Middle Stoicism; and Antiochus of Ascalon, the head of the Academy, who led it back from Skepticism and prepared Middle Platonism, which paved the way for Neoplatonism. Originally presented as a series of lectures before the Scuola Normale Superiore in Pisa, Italy, Greek Philosophers of the Hellenistic Age assesses a group of philosophers who exerted an enormous influence upon pagan and Christian writers of late antiquity - including Cicero and St. Augustine - and on many medieval and early modern philosophers, theologians, and other thinkers.

ABSTRACT The notion of consensus plays an important epistemological role in modern welfare economics, in that unanimous consent is a (unique) conceptual test for those changes that are ‘Pareto-desirable’ (that is, make someone better off and no-one else worse). In this paper, we seek to show that unanimous consent does not logically imply Pareto-desirability—that a rational individual may fail to veto policy changes that make him/her worse off. The central element in the proof of this proposition is the observation that (...) in social agreements involving a significant number of participants, any one individual's veto is decisive if it is the only veto. If the individual does not expect to be decisive, he will rationally exercise his vote ‘expressively’, and without sole regard to its consequences. When all individuals so act, a sort of prisoners' dilemma interaction may emerge, even under explicit consensus. (shrink)

Sovereign is he who provides the exception.…The exception is more interesting than the rule. The rule proves nothing; the exception proves everything. In the exception the power of real life breaks through the crust of a mechanism that has become torpid by repetition.In spring 2020, in response to the COVID-19 crisis, world leaders imposed severe restrictions on citizens’ civil, political, and economic liberties.
