The papers which constitute this volume, and which were first presented at a Conference in 1978 at the Catholic University of America, are arranged chronologically according to the five periods in which Neoplatonism confronted Christianity: Patristic, Later Greek and Byzantine, Medieval Latin, Renaissance, and Modern. Its editor suggests, in his valuable "Introduction", that the papers fall also into three groups in line with their contents. The first group concerns Christian thinkers who knew and used specific Neoplatonic texts and includes the (...) following: H. D. Saffrey, "New Objective Links Between the Pseudo-Dionysius and Proclus"; J. Dillon, "Origen's Doctrine of the Trinity and Some Later Neoplatonic Theories"; J. Pépin, "The Platonic and Christian Ulysses"; M. T. Clark, "A Neoplatonic Commentary on the Christian Trinity: Marius Victorinus"; J. O'Meara, "The Neoplatonism of Saint Augustine"; G. H. Allard, "The Primacy of Existence in the Thought of Eriugena"; C. Fabro, "The Overcoming of the Neoplatonic Triad of Being, Life and Intellect by Thomas Aquinas"; B. McGinn, "Meister Echkart on God as Absolute Unity"; E. Bieman, "Triads and Trinity in the Poetry of Robert Browning"; M. Rose, "The Christian Platonism of C. S. Lewis, J. R. R. Tolkien and Charles Williams.". (shrink)

Carbon monoxide (CO), a product of organic oxidation processes, arises in vivo during cellular metabolism, most notably heme degradation. CO binds to the heme iron of most hemoproteins. Tissue hypoxia following hemoglobin saturation represents a principle cause of CO‐induced mortality in higher organisms, though cellular targets cannot be excluded. Despite extreme toxicity at high concentrations, low concentrations of CO can confer cytoprotection during ischemia/reperfusion or inflammation‐induced tissue injury. Likewise, heme oxygenase, an enzyme that produces CO, biliverdin and iron, as well (...) as a secondary increase in ferritin synthesis, from the oxidation of heme, can confer protection in vivo and in vitro. CO has been shown to affect several intracellular signaling pathways, including guanylate cyclase, which generates guanosine 3′:5′ cyclic monophosphate and the mitogen‐activated protein kinases (MAPK). Such pathways mediate, in part, the known vasoregulatory, anti‐inflammatory, anti‐apoptotic and anti‐proliferative effects of this gas. Exogenous CO delivered at low concentrations is showing therapeutic potential as an anti‐inflammatory agent and as such can modulate numerous pathophysiological states. This review will delve into the biological significance and medical applications of this gas molecule. BioEssays 26:270–280, 2004. © 2004 Wiley Periodicals, Inc. (shrink)

Collaboration requires agents to coordinate their behavior on the fly, sometimes cooperating to solve a single task together and other times dividing it up into sub‐tasks to work on in parallel. Underlying the human ability to collaborate is theory‐of‐mind (ToM), the ability to infer the hidden mental states that drive others to act. Here, we develop Bayesian Delegation, a decentralized multi‐agent learning mechanism with these abilities. Bayesian Delegation enables agents to rapidly infer the hidden intentions of others by inverse planning. (...) We test Bayesian Delegation in a suite of multi‐agent Markov decision processes inspired by cooking problems. On these tasks, agents with Bayesian Delegation coordinate both their high‐level plans (e.g., what sub‐task they should work on) and their low‐level actions (e.g., avoiding getting in each other's way). When matched with partners that act using the same algorithm, Bayesian Delegation outperforms alternatives. Bayesian Delegation is also a capable ad hoc collaborator and successfully coordinates with other agent types even in the absence of prior experience. Finally, in a behavioral experiment, we show that Bayesian Delegation makes inferences similar to human observers about the intent of others. Together, these results argue for the centrality of ToM for successful decentralized multi‐agent collaboration. (shrink)

As interest in working memory is increasing at a rapid pace, an open discussion of the central issues involved is both useful and timely. This new volume compares and contrasts conceptions of working memory, with contributions from proponents of different views.

In the remainder of this article, we will disarm an important motivation for epistemic contextualism and interest-relative invariantism. We will accomplish this by presenting a stringent test of whether there is a stakes effect on ordinary knowledge ascription. Having shown that, even on a stringent way of testing, stakes fail to impact ordinary knowledge ascription, we will conclude that we should take another look at classical invariantism. Here is how we will proceed. Section 1 lays out some limitations of previous (...) research on stakes. Section 2 presents our study and concludes that there is little evidence for a substantial stakes effect. Section 3 responds to objections. The conclusion clears the way for classical invariantism.

Professor Copi provides us with the following example:Remove all cards except aces and kings from a deck, so that only eight cards remain, of which four are aces and four are kings. From this abbreviated deck, deal two cards to a friend. If he looks at his cards and announces that his hand contains an ace, what is the probability that both his cards are aces? If he announces instead that one of his cards is the ace of spades, what (...) is the probability then that both his cards are aces? (shrink)

A distressing number of philosophers and classicists think that the deuteros plous or “second best” mentioned at Phaedo 99c9-dl is the hypothetical method. Many of them will even tell you that Plato says the hypothetical method is the deuteros plous, and that they are not merely interpreting his meaning. They usually back off, however, when challenged on this point, for there jus isn’t any such statement by Plato. Nor, I think, does Plato give us any justification at all for taking (...) the deuteros plous as the hypothetical method. I will argue in this paper that he is referring rather to the explanation of things in terms of their formal causes, and that this sort of explanation is “second best” when compared to a teleological explanation in terms of final causes. The hypothetical method of the dialectician is simply the logical device or apparatus by means of which the theory of ideas and the attendant notion of formal causation are introduced into the discussion; it is not a “second best” method and is not inferior to anything else.

Is behavioral integration a necessary feature of belief in folk psychology? Our data from over 5,000 people across 26 samples, spanning 22 countries suggests that it is not. Given the surprising cross-cultural robustness of our findings, we argue that the types of evidence for the ascription of a belief are, at least in some circumstances, lexicographically ordered: assertions are first taken into account, and when an agent sincerely asserts that p, nonlinguistic behavioral evidence is disregarded. In light of this, we (...) take ourselves to have discovered a universal principle governing the ascription of beliefs in folk psychology. (shrink)

Is behavioral integration (i.e., which occurs when a subjects assertion that p matches her non-verbal behavior) a necessary feature of belief in folk psychology? Our data from nearly 6,000 people across twenty-six samples, spanning twenty-two countries suggests that it is not. Given the surprising cross-cultural robustness of our findings, we suggest that the types of evidence for the ascription of a belief are, at least in some circumstances, lexicographically ordered: assertions are first taken into account, and when an agent sincerely (...) asserts that p, non-linguistic behavioral evidence is disregarded. In light of this, we take ourselves to have discovered a universal principle governing the ascription of beliefs in folk psychology. (shrink)

Zoos and aquariums have an enormous global reach and hence an ability to craft meaningful conservation action for threatened species, implement educational strategies to encourage human engagement, development and behavior change, and conduct scientific research to enhance the husbandry, roles and impacts of the living collection. The recreational role of the zoo is also vast- people enjoy visiting the zoo and this is often a shared experience amongst family and friends. Evaluating how the zoo influences this “captive audience” and extending (...) its reach to include a compassionate approach to animals and people can further enhance the mission, value, and relevance of their work. The modern zoo’s current aims—Conservation, Education, Research and Recreation—provide useful foundations for the activities that zoos conduct at a local and national level. However, to improve sustainability of their actions and outcomes, we feel that Wellbeing should become the fifth aim of the modern zoo for the future- both from an animal perspective and from a human perspective. This paper provides discussion and review of how Wellbeing is already a substantial part of what zoos work on as well as posing the idea of altering the Recreation aim of the zoo to one of Engagement, which potentially is more measurable and therefore can allow zoo researchers and managers further options for the collection of evidence on the local and global reach of their zoo’s aims. Education, Engagement, Conservation, Research and Wellbeing provide a more complete picture of the roles of the modern zoo for the animals, human visitors and workforce, and to society more widely.

This article examines whether people share the Gettier intuition (viz. that someone who has a true justified belief that p may nonetheless fail to know that p) in 24 sites, located in 23 countries (counting Hong Kong as a distinct country) and across 17 languages. We also consider the possible influence of gender and personality on this intuition with a very large sample size. Finally, we examine whether the Gettier intuition varies across people as a function of their disposition to (...) engage in “reflective” thinking. (shrink)

Based on talks provided under the title "The Christian religion & its philosophy".

Does the Ship of Theseus present a genuine puzzle about persistence due to conflicting intuitions based on “continuity of form” and “continuity of matter” pulling in opposite directions? Philosophers are divided. Some claim that it presents a genuine puzzle but disagree over whether there is a solution. Others claim that there is no puzzle at all since the case has an obvious solution. To assess these proposals, we conducted a cross-cultural study involving nearly 3,000 people across twenty-two countries, speaking eighteen (...) different languages. Our results speak against the proposal that there is no puzzle at all and against the proposal that there is a puzzle but one that has no solution. Our results suggest that there are two criteria—“continuity of form” and “continuity of matter”— that constitute our concept of persistence and these two criteria receive different weightings in settling matters concerning persistence.

Innovations in web technologies, data warehousing and data mining enable Internet marketers to collect, process and analyze personal data gathered from web users browsing and online purchase habits on a much greater scale as it is now quicker and more economical to do so. Recent surveys indicate that consumers are not comfortable with these practices, especially when the data is collected or sold without their consent. The resulting conflict of interest demands a solution. In this paper, a framework of incomplete (...) markets, property rights and transaction costs is used to analyze the problem and propose some preliminary solutions. (shrink)
