In this paper I ask how Timaeus explains change within the trianglebased part of his cosmos. Two common views are that change among physical items is somehow caused or enabled by either the forms or the demiurge. I argue for a competing view, on which the physical items are capable of bringing about change by themselves, prior to the intervention of the demiurge, and prior to their being turned into imitations of the forms. I outline three problems for the view (...) that physical things depend on the forms for their causal powers, and show how the view I propose solves each. I then add further arguments for my view, based on (a) statements by Timaeus that seem to favor my view directly, (b) implications of Timaeus’ positions that favor the view, and (c) Timaeus’ explanatory practice in the second half of his speech.

Although the Phaedo never mentions a Form of Soul explicitly, the dialogue implies this Form’s existence. First, a number of passages in which Socrates describes his views about Forms imply that there are very many Forms; thus, Socrates’ general description of his theory gives no ground for denying that there is a Form of Soul. Second, the final argument for immortality positively requires a Form of Soul.

Near the end of his speech, Timaeus outlines a theory of bodily health and disease which has seemed to many commentators loosely unified or even inconsistent . But this section is better unified than it has appeared, and gives us at least one important insight into the workings of physical causality in the Timaeus. I argue first that the apparent disorder in Timaeus’s theory of disease is likely a deliberate effect planned by the author. Second, the taxonomy of disease in (...) the passage consists of one genus subsuming two species. Third, in Timaeus’s theory, health lies between perfect stability and a chaos of all possible motions; this indicates a conception of health as the activation of the body's powers in the right way. A power is a property directed towards bringing about some change. Fourth, the activation of these powers can change depending on the location of their possessors. This last point shows that causation among the physical items in the Timaeus involves structures as well as pushes. (shrink)

Written by a group of leading scholars, this unique collection of essays investigates the views of both pagan and Christian philosophers on causation and the creation of the cosmos. Structured in two parts, the volume first looks at divine agency and how late antique thinkers, including the Stoics, Plotinus, Porphyry, Simplicius, Philoponus and Gregory of Nyssa, tackled questions such as: is the cosmos eternal? Did it come from nothing or from something pre-existing? How was it caused to come into existence? (...) Is it material or immaterial? The second part looks at questions concerning human agency and responsibility, including the problem of evil and the nature of will, considering thinkers such as Plotinus, Porphyry, Proclus and Augustine. Highlighting some of the most important and interesting aspects of these philosophical debates, the volume will be of great interest to upper-level students and scholars of philosophy, classics, theology and ancient history.

The interplay between violence, religion, and politics is a central problem for societies and has attracted the attention of important philosophers, including Martin Heidegger, Jacques Derrida, and René Girard. Centuries earlier during the Italian Renaissance, these same problems drew the interest of Niccolò Machiavelli. In Not Even a God Can Save Us Now, Brian Harding argues that Machiavelli’s work anticipates – and often illuminates – contemporary theories on the place of violence in our lives. While remaining cognizant of the (...) historical and cultural context of Machiavelli’s writings, Harding develops Machiavelli’s accounts of sacrifice, truth, religion, and violence and places them in conversation with those of more contemporary thinkers. Including in-depth discussions of Machiavelli’s works The Prince and Discourses on Livy, as well as his Florentine Histories, The Art of War, and other less widely discussed works, Harding interprets Machiavelli as endorsing sacrificial violence that founds or preserves a state, while censuring other forms of violence. This reading clarifies a number of obscure themes in Machiavelli’s writings, and demonstrates how similar themes are at work in the thought of recent phenomenologists. The first book to approach both Machiavellian and contemporary continental thought in this way, Not Even a God Can Save Us Now is a highly original and provocative approach to both the history of philosophy and to contemporary debates about violence, religion, and politics.

Giovanni Pico della Mirandola had his 900 Conclusions printed late in 1486, just a few weeks before Pope Innocent VIII attacked thirteen of them. Did Pico intend to provoke the Vatican? If not, what was his aim, what were his means and what was the product? The Conclusions looks like a miscellany, just as Pico described it. But disorder was only on the surface, in line with a purpose explicitly stated: keeping the holiest truths hidden. Pico’s informants about esoteric wisdom (...) included more than two dozen authorities—some named as individuals, others unnamed, some ancient, others medieval—listed in the first of two parts of the Conclusions. Not named at all were contemporaries and near contemporaries who introduced the prince to these sages from the past. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Tragic Evolutionary Logic of The IliadBrian BoydThe Rape of Troy: Evolution, Violence, and the World of Homer, by Jonathan Gottschall; xii & 223 pp. Cambridge: Cambridge University Press, 2008, $32.00 paperback.Jonathan Gottschall has conquered the oldest and craggiest peak of Western literature, The Iliad, by a new face. He stakes out the Darwin route to Homer so directly and clearly that he makes the climb inviting and inspiring (...) even to curious newcomers without high-altitude evolutionary training. And the vista he opens up offers us a chance to look in multiple directions: at Homer, at literary evolutionism and its possibilities, and at Gottschall's role in exploring this new route to discovery.One previous monograph has investigated a single literary work from a Darwinian viewpoint: Brett Cooke's analysis of Evgeny Zamyatin's 1921 science-fiction classic, We.1 Cooke's Human Nature in Utopia, by showing how Zamyatin appeals to the evolved nature of readers, in the face of the denial of human nature in his imagined One State and in early Soviet Communism, deepens our natural response to a modern classic. But where Cooke merely succeeds, Gottschall triumphs. The Rape of Troy not only deepens our response to a classic discussed for almost three millennia but also explains the world of Homer in a way no one could have seen without the multi-million-year perspective evolution allows—and does so with conceptual clarity, tight argument, effortless imagery, and copious verbal energy. [End Page 234]Gottschall emphasizes that his "evolutionary anthropology of conflict in Homeric society" does not attempt a Homeric "theory of everything" (pp. 3, 9). There is much of interest in The Iliad he does not touch on, and much even in possible evolutionary approaches to Homer that he does not consider. He focuses intently on a single two-part question: Why is there so much violence in the Iliad, and what effect does it have on how those in Homeric society see their world?After a brilliant introductory overview, he shows in his first two chapters how over the last century Homerists have increasingly turned to comparative anthropology to augment the meagre direct data. They have clarified that the Iliad was long obscured by later Western assumptions about states and kings, and that the poem probably reflects something like Homer's own world, within (at about 800 BCE) the late Greek Dark Age, a pre-state society in many ways closer to Highland New Guinea than to the worlds of Caesar or Charlemagne.Everyone who knows about the Trojan War knows that the Greeks fight Troy because the Trojan prince Paris took Helen from her husband, the Greek lord Menelaus. But readers of the Iliad want to know why thousands of soldiers on both sides persisted through ten years of brutal battle. Surely war on this scale cannot have been over just a woman? Scholars have proposed many explanations of what was really at stake. Immortal honor for men all too aware, day after bloody day, of their own physical mortality? Power? Status? Material goods? Prestige goods? A chance to neutralize enemies?By drawing on evolutionary biology and anthropology, Gottschall can show that this war, like most human violence against other humans, and even like most intraspecies animal violence, stems ultimately from male competition over females. He introduces the powerful and far-reaching principle of differential parental investment developed by Robert Trivers.2 As Gottschall lucidly elaborates: "males will attempt to mate more promiscuously both because sex is cheaper for them, and because they have the potential to produce many offspring with multiple females. I emphasize the words 'attempt' and 'potential' because if every male adopts a relatively promiscuous strategy, and if some males succeed, then other males will not reproduce at all" (p. 44). The far more divergent rates of reproductive success among males than among females prove to be the key determinant. Gottschall sums up: "males typically face higher risks of total reproductive failure and higher hopes of extraordinary reproductive success. This creates strong incentives to compete for mates. Males who are better able to compete for access to [End Page 235] scarce female reproductive capacity, in whatever form... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Conquest and English Legal Identity in Renaissance IrelandBrian LockeyLike the Spanish administrators of the American territories, English administrators of Ireland attempted to impose their own native legal system on the Irish inhabitants. Nonetheless, important differences existed between the two kingdoms' legal approaches to their respective colonial contexts. Because Spanish jurisprudence was allied with universalist Catholic doctrine and was officially based on Justinian's Corpus Iuris Civilis (the ancient Roman legal (...) code which had close affinities to natural law discourse), Spanish administrators expected New World inhabitants to accept what they considered to be the "universal values" that were inherent in Spanish law.1 In contrast English common law had its roots not in natural law but in the peculiar customs of the English people. Thus, while the Spanish were able to claim that they were replacing unnatural Indian customs with a legal system rooted in universal natural law, the English were attempting to reform what they considered to be the unnatural practices of the Irish by imposing a legal system defined by its insularity and its peculiar affinity with English institutions.2 In this essay I show that Renaissance ethnographies on Ireland by such English administrators of Ireland as Edmund Spenser, Sir John Davies, and Fynes Moryson are fractured by a conflict between a commitment to natural-law theory, which had its origin in continental writings, and a corresponding commitment to the native English tradition of common law. I examine how works by Spenser, Davies, and Moryson dealt with this conflict within their collective project of articulating a legal justification and strategy for the pacification of Ireland. [End Page 543]Despite reports throughout Europe of Spanish-perpetrated cruelty throughout the Americas, the idea that war or conquest could be just or even charitable when prosecuted against oppression originated within the Catholic tradition of scholastic just-war theory.3 Many of the sixteenth-century writers who were writing about war and conquest in legal or ethical terms were Spanish or continental theologians who had attempted to evaluate Spanish imperial policy in the New World. On the one side were such figures as the Scottish theologian John Major and Spanish historian Juan Ginés de Sepúlveda, both of whom had justified Spanish conquest and treatment of the Indians using arguments based on the foundation of natural law.4 On the other side were those who had, on similar terms, voiced criticisms of the cruelties which Spanish forces were inflicting on the Indians. Francisco de Vitoria and Bartolomé de las Casas were certainly the most notable Spanish writers who favored more ethical treatment of New World inhabitants.5 Other prominent defenders of Indian rights were Domingo de Soto and Melchor Cano.6 Whether directly or through intermediaries, the ideas of many of these writers permeated the ideological fabric of England.Sir Fulke Greville's famous statement about Sir Philip Sidney's goal of fostering alliances with New World inhabitants in order to overthrow the Spanish authorities included an awareness of the "inhuman cruelties" of the Spanish forces, an awareness that probably originated in the English translation of Las Casas's Brevissima relación de la destrucyión de las Indias (1552).7 Beyond [End Page 544] this significant text, however, there were others. One important book that captured the ideas of the early Spanish debates on the ethics and justice of the New World conquests was Antonio de Guevara's Relox de príncipes (1529), a work twice translated into English during the sixteenth century.8 The third book of the Relox de príncipes, which treats the princely virtues of justice, peace, and magnificence, contains several sections that together constitute a polemic against violent imperialism and unjust conquest. In one notable episode Guevara employs the example of ancient Roman imperialism to produce a veiled critique of the injustices which Spain had committed against New World polities. A "villain of Danuby" from a German province newly conquered by Rome makes a speech to the Roman senate in which he criticizes the injustice of his Roman oppressors. The German villain characterizes the conquest of Germany in the following terms: "For I let you know, if you do not know it, that when... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Valla Our Contemporary:Philosophy and PhilologyBrian P. CopenhaverEven before the Italians knew what to call their Renaissance, they knew the names of its heroes, one of whom was Lorenzo Valla. Accordingly, by the time Count Terenzio Mamiani della Rovere published one of the first modern histories of Italian philosophy in 1834, Valla's place in the story of that subject had long been established-for Italians, at least. "He began by ridiculing (...) blind trust in Aristotle's words," wrote Mamiani,and then went on to show how the highest categories and first predicables had been based on false assumptions, proving this by the correct meaning of terms, by the usage of speakers and by arguments from common sense. Valla overthrew the classifications of Porphyry in the same way. He shows how the basic rules of logic are simple and completely self-evident.1 [End Page 507]In tribute to Salvatore Camporeale of the Order of Preachers, I shall preach a sermon about this celebrated Italian philosopher. My text is an article on Valla that Campo published in 1986, and my contention is that Valla was a remarkably original thinker who has been much underrated in the Anglophone world, in part because he has not been read often enough or carefully enough in a contemporary philosophical framework.2The Philosopher's Index is the most important general bibliography for philosophers now writing in English. The on-line version that gives nearly four thousand references in five languages for Descartes, over nine thousand for Aristotle, and nearly ten thousand for Kant turns up only forty-two for Valla; twenty-five of these are in English, but only two are in major Anglophone journals of philosophy.3 I call that underrated and understudied.The first English-language entry for Valla in the Philosopher's Index dates from 1948, The Renaissance Philosophy of Man, a very influential book of readings (still in print) that presents Valla as a moral philosopher and Renaissance philosophy as not terribly important. The next entry, from 1964, refers to an equally influential book, Paul Kristeller's Eight Philosophers of the Italian Renaissance, one of whom is Valla, described by Kristeller not only as a moral philosopher but also, and more importantly, as a philosophical critic of logic and language.4 Around the same time, Hanna Gray, Jerrold Seigel, Charles Trinkaus, and others in this country had begun to study Valla's theory of language in more depth, and a few years later Camporeale's masterful book on Valla appeared in 1972.5Since Camporeale's book was then and is now the best account in any language of a brilliant philosopher, its absence from the Philosopher's Index indicates a kind of oblivion in Anglophone philosophy. In Europe and especially in Italy, by contrast, interest in Valla has been more or less continuous since his death in 1457. Mario Nizolio continued Valla's work in the sixteenth century, and both Valla and Nizolio were well known to Leibniz, who in turn [End Page 508] was the subject of an important book by Bertrand Russell in 1900.6 Russell's most popular work, however, was the History of Western Philosophy that he wrote much later, during the Second World War.7Many people have taken their bearings on the history of philosophy from Russell's exuberant History. Amazon.com still offers five editions by four publishers. And Amazon's rankings of sales of more recent accounts of the Renaissance period, the Cambridge History of Renaissance Philosophy and the Renaissance Philosophy volume of Oxford's History of Western Philosophy, lag far behind the figures for a single edition of Russell's broader treatment (8,970 Russell; 481,085 Cambridge; 507,316 Oxford).8Despite its great success, Russell's book does not do well by our topic. His treatment of the Renaissance is like Burckhardt directed by Victor Hugo and produced by Macaulay. Cardinals poison each other while free-thinking scholars entertain princes to procure patronage. Humanism meanwhile dozes under the rubble of antiquity, too dazed by the ruins to produce original philosophy. The only philosophical good to come from philology was its odium.

Although the body has been the focus of much contemporary cultural theory, the models that are typically applied neglect the most salient characteristics of embodied existence—movement, affect, and sensation—in favor of concepts derived from linguistic theory. In _Parables for the Virtual_ Brian Massumi views the body and media such as television, film, and the Internet, as cultural formations that operate on multiple registers of sensation beyond the reach of the reading techniques founded on the standard rhetorical and semiotic models. (...) Renewing and assessing William James’s radical empiricism and Henri Bergson’s philosophy of perception through the filter of the post-war French philosophy of Deleuze, Guattari, and Foucault, Massumi links a cultural logic of variation to questions of movement, affect, and sensation. If such concepts are as fundamental as signs and significations, he argues, then a new set of theoretical issues appear, and with them potential new paths for the wedding of scientific and cultural theory. Replacing the traditional opposition of literal and figural with new distinctions between stasis and motion and between actual and virtual, _Parables for the Virtual _tackles related theoretical issues by applying them to cultural mediums as diverse as architecture, body art, the digital art of Stelarc, and Ronald Reagan’s acting career. The result is an intriguing combination of cultural theory, science, and philosophy that asserts itself in a crystalline and multi-faceted argument. _Parables for the Virtual_ will interest students and scholars of continental and Anglo-American philosophy, cultural studies, cognitive science, electronic art, digital culture, and chaos theory, as well as those concerned with the “science wars” and the relation between the humanities and the sciences in general.

Dogmatism is sometimes thought to be incompatible with Bayesian models of rational learning. I show that the best model for updating imprecise credences is compatible with dogmatism.

When making substituted judgments for incapacitated patients, surrogates often struggle to guess what the patient would want if they had capacity. Surrogates may also agonize over having the (sole) responsibility of making such a determination. To address such concerns, a Patient Preference Predictor (PPP) has been proposed that would use an algorithm to infer the treatment preferences of individual patients from population-level data about the known preferences of people with similar demographic characteristics. However, critics have suggested that even if such (...) a PPP were more accurate, on average, than human surrogates in identifying patient preferences, the proposed algorithm would nevertheless fail to respect the patient’s (former) autonomy since it draws on the ‘wrong’ kind of data: namely, data that are not specific to the individual patient and which therefore may not reflect their actual values, or their reasons for having the preferences they do. Taking such criticisms on board, we here propose a new approach: the Personalized Patient Preference Predictor (P4). The P4 is based on recent advances in machine learning, which allow technologies including large language models to be more cheaply and efficiently ‘fine-tuned’ on person-specific data. The P4, unlike the PPP, would be able to infer an individual patient’s preferences from material (e.g., prior treatment decisions) that is in fact specific to them. Thus, we argue, in addition to being potentially more accurate at the individual level than the previously proposed PPP, the predictions of a P4 would also more directly reflect each patient’s own reasons and values. In this article, we review recent discoveries in artificial intelligence research that suggest a P4 is technically feasible, and argue that, if it is developed and appropriately deployed, it should assuage some of the main autonomy-based concerns of critics of the original PPP. We then consider various objections to our proposal and offer some tentative replies. (shrink)

Gossip is often serious business, not idle chitchat. Gossip allows those oppressed to privately name their oppressors as a warning to others. Of course, gossip can be in error. The speaker may be lying or merely have lacked sufficient evidence. Bias can also make those who hear the gossip more or less likely to believe the gossip. By examining the social functions of gossip and considering the differences in power dynamics in which gossip can occur, we contend that gossip may (...) be not only permissible but virtuous, both as the only reasonable recourse available and as a means of resistance against oppression.

Abstract Utterances of counterfactual conditionals are typically attended by the information that their antecedents are false. But there is as yet no account of the source of this information that is both detailed and complete. This paper describes the problem of counterfactual antecedent falsity and argues that the problem can be addressed by appeal to an adequate account of the presuppositions of various competing conditional constructions. It argues that indicative conditionals presuppose that their antecedents are epistemically possible, while subjunctive conditionals (...) bear no presupposition. Given this arrangement, utterance of the counterfactual results in an antipresupposition, that is, a scalar implicature generated from the presuppositions of competing alternatives rather than from the at-issue content of competing alternatives. The content of the antipresupposition is the negation of the presupposition of the competing indicative, i.e., that the antecedent of the conditional is known to be false by the speaker. (shrink)

More and more people would like to migrate, but find that every state places barriers in their way. At the same time, most governments not only permit but court foreign investment. Can this difference between the treatment of people and the treatment of money be justified?

This book uses computer modeling to investigate trends in what is published in leading philosophy journals over the last century and a half. The notable trends include the rise of realism from a fringe view to the mainstream metaphysical outlook, the increase in specialization, and the increasing depth of integration between philosophy and physical sciences. It also contains a guide to how to do similar investigations, and discussions of the strengths and weaknesses of the approach.

Background: Recent literature on addiction and judgments about the characteristics of agents has focused on the implications of adopting a ‘brain disease’ versus ‘moral weakness’ model of addiction. Typically, such judgments have to do with what capacities an agent has (e.g., the ability to abstain from substance use). Much less work, however, has been conducted on the relationship between addiction and judgments about an agent’s identity, including whether or to what extent an individual is seen as the same person after (...) becoming addicted. Methods: We conducted a series of vignette-based experiments (total N = 3,620) to assess lay attitudes concerning addiction and identity persistence, systematically manipulating key characteristics of agents and their drug of addiction. Conclusions: In Study 1, we found that US participants judged an agent who became addicted to drugs as being closer to ‘a completely different person’ than ‘completely the same person’ as the agent who existed prior to the addiction. In Studies 2-6, we investigated the intuitive basis for this result, finding that lay judgments of altered identity as a consequence of drug use and addiction are driven primarily by perceived negative changes in the moral character of drug users, who are seen as having deviated from their good true selves.

Color coded terror alerts, invasion, drone war, rampant surveillance: all manifestations of the type of new power Brian Massumi theorizes in _Ontopower_. Through an in-depth examination of the War on Terror and the culture of crisis, Massumi identifies the emergence of preemption, which he characterizes as the operative logic of our time. Security threats, regardless of the existence of credible intelligence, are now felt into reality. Whereas nations once waited for a clear and present danger to emerge before using (...) force, a threat's felt reality now demands launching a preemptive strike. Power refocuses on what _may_ emerge, as that potential presents itself to feeling. This affective logic of potential washes back from the war front to become the dominant mode of power on the home front as well. This is ontopower—the mode of power embodying the logic of preemption across the full spectrum of force, from the “hard” to the "soft". With _Ontopower_, Massumi provides an original theory of power that explains not only current practices of war but the culture of insecurity permeating our contemporary neoliberal condition.

The nature of measurement is a topic of central concern in the philosophy of science and, indeed, measurement is the essential link between science and mathematics. Professor Ellis's book, originally published in 1966, is the first general exposition of the philosophical and logical principles involved in measurement since N. R. Campbell's Principles of Measurement and Calculation, and P. W. Bridgman's Dimensional Analysis. Professor Ellis writes from an empiricist standpoint. His object is to distinguish and define the basic concepts in measurement, (...) for example: scale, quantity, unit. dimension, number and probability.

We conclude by discussing concerns that moral neuroenhancement might restrict freedom or otherwise “misfire,” and (...) argue that these concerns are not as damning as they may seem at first.

Many philosophers of emotion, whether perceptual or cognitive theorists, have claimed that emotions represent evaluative properties. This is often supported by an appeal to the fittingness of emotion: that emotions can be fitting shows they represent evaluative properties. In this paper, however, I argue that this inference is much too fast. In fact, no aspect of the rational assessment of emotion directly supports the claim that emotions represent evaluative properties. This inference can, however, be matured into an inference to the (...) best explanation. But this requires coming to terms with a significant emerging rival, the attitudinal theory of emotion. In this paper, I show how this can be accomplished and the inference from fittingness to content saved. (shrink)

What question are decision theorists trying to answer, and why is it worth trying to answer it? A lot of philosophers talk as if the aim of decision theory is to describe how we should make decisions, and the reason to do this is to help us make better decisions. I disagree on both fronts. The aim of the decision theory is to describe how a certain kind of idealised decider does in fact decide. And the reason to do this (...) is that this idealisation, like many other idealisations, helps generate explanations of real-world behaviour. We shouldn't do what these ideal deciders do, or try to be more like them, because a lot of what they do only makes sense because of the differences between us and them. Still, sometimes those differences are small enough that they can be ignored in explanations, and that's when decision theory is useful. (shrink)

What the world needs now is another theory of vagueness. Not because the old theories are useless. Quite the contrary, the old theories provide many of the materials we need to construct the truest theory of vagueness ever seen. The theory shall be similar in motivation to supervaluationism, but more akin to many-valued theories in conceptualisation. What I take from the many-valued theories is the idea that some sentences can be truer than others. But I say very different things to (...) the ordering over sentences this relation generates. I say it is not a linear ordering, so it cannot be represented by the real numbers. I also argue that since there is higher-order vagueness, any mapping between sentences and mathematical objects is bound to be inappropriate. This is no cause for regret; we can say all we want to say by using the comparative truer than without mapping it onto some mathematical objects. From supervaluationism I take the idea that we can keep classical logic without keeping the familiar bivalent semantics for classical logic. But my preservation of classical logic is more comprehensive than is normally permitted by supervaluationism, for I preserve classical inference rules as well as classical sequents. And I do this without relying on the concept of acceptable precisifications as an unexplained explainer. The world does not need another guide to varieties of theories of vagueness, especially since Timothy Williamson (1994) and Rosanna Keefe (2000) have already provided quite good guides. I assume throughout familiarity with popular theories of vagueness. (shrink)

The question of what makes someone the same person through time and change has long been a preoccupation of philosophers. In recent years, the question of what makes ordinary or lay people judge that someone is—or isn’t—the same person has caught the interest of experimental psychologists. These latter, empirically oriented researchers have sought to understand the cognitive processes and eliciting factors that shape ordinary people’s judgments about personal identity and the self. Still more recently, practitioners within an emerging discipline, experimental (...) philosophical bioethics or “bioxphi”—the focus of this chapter—have adopted a similar aim and employed similar methodologies, but with two distinctive features: (a) a special concern for enhanced ecological validity in the examples and populations studied; and (b) an interest in contributing to substantive normative debates within the wider field of bioethics. Our aim in this chapter is to sample illustrative work on personal identity in bioxphi, explore how it relates to studies in psychology covering similar terrain, and draw out the implications of this work for matters of bioethical concern. In pursuing these issues, we highlight recent work in bioxphi that includes the perceived validity of advance directives following neurodegeneration, the right of psychologically altered study participants to withdraw from research, how drug addiction may cause one to be regarded by others as “a completely different person,” the effect of deep-brain stimulation on perceptions of the self, and the potential influence of moral enhancement interventions on intuitive impressions of a person’s character.

A common view among nontheists combines the de jure objection that theism is epistemically unacceptable with agnosticism about the de facto objection that theism is false. Following Plantinga, we can call this a “proper” de jure objection—a de jure objection that does not depend on any de facto objection. In his Warranted Christian Belief, Plantinga has produced a general argument against all proper de jure objections. Here I first show that this argument is logically fallacious (it makes subtle probabilistic fallacies (...) disguised by scope ambiguities), and proceed to lay the groundwork for the construction of actual proper de jure objections.

This paper contributes to the project of articulating and defending the supra-Bayesian approach to judgment aggregation.

But this doesn’t settle how the update on pairs (...) of experts should go, because we also need to know how the experts are related. I work through three examples showing how the results change given different prior beliefs about this relationship. (shrink)

Orthodox Bayesian decision theory requires an agent’s beliefs representable by a real-valued function, ideally a probability function. Many theorists have argued this is too restrictive; it can be perfectly reasonable to have indeterminate degrees of belief. So doxastic states are ideally representable by a set of probability functions. One consequence of this is that the expected value of a gamble will be imprecise. This paper looks at the attempts to extend Bayesian decision theory to deal with such cases, and concludes (...) that all proposals advanced thus far have been incoherent. A more modest, but coherent, alternative is proposed. Keywords: Imprecise probabilities, Arrow’s theorem. (shrink)

The central thesis of this paper is that fake news and related phenomena serve as defeaters for knowledge transmission via journalistic channels. This explains how they pose a threat to democracy; and it points the way to determining how to address this threat. Democracy is both intrinsically and instrumentally good provided the electorate has knowledge (however partial and distributed) of the common good and the means of achieving it. Since journalism provides such knowledge, those who value democracy have a reason (...) to protect it. Hostile agents, however, can undermine both the effectiveness of democratic decision-making and faith in democracy itself, by deliberately promulgating fake news and hyper-partisan views; moreover, these effects can come about unintentionally on social media. I conclude that we may need to change, not just the way we process information online, but also the informational environment in which we operate. (shrink)

Safety-based theories of knowledge face a difficulty surrounding necessary truths: no subject could have easily falsely believed such a proposition. Failing to predict that ill-grounded beliefs in such propositions do not constitute knowledge, standard safety theories are therefore less informative than desired. Some have suggested that the subjects at issue could easily have believed some related false proposition; but they have given no indication as to what makes a proposition related. I suggest a solution to this problem: a belief is (...) safe iff its subject could not easily have believed a false answer to the same question. (shrink)

When we say that what two people feel for each other is 'true love,' we seem to be doing more than simply clarifying that it is in fact love they feel, as opposed to something else. That is, an experience or relationship might be a genuine or actual instance of love without necessarily being an instance of true love. But what criteria do people use to determine whether something counts as true love? This chapter explores three hypotheses. The first holds (...) that the ordinary concept of true love picks out love that is highly prototypical. The second, that it picks out love that is especially good or valuable. The third, that people distinguish between psychological states that are 'real' or not, and that it picks out love that is real. Two experiments provide evidence against the first hypothesis and in favor of the second and third. Implications for real-life disagreements about love are also discussed. (shrink)
