Condorcet's jury theorem shows that when the members of a group have noisy but independent information about what is best for the group as a whole, majority decisions tend to outperform dictatorial ones. When voting is supplemented by communication, however, the resulting interdependencies between decision makers can strengthen or undermine this effect: they can facilitate information pooling, but also amplify errors. We consider an intriguing non-human case of independent information pooling combined with communication: the case of nest-site choice by honeybee (...) (Apis mellifera) swarms. It is empirically well documented that when there are different nest sites that vary in quality, the bees usually choose the best one. We develop a new agent-based model of the bees' decision process and show that its remarkable reliability stems from a particular interplay of independence and interdependence between the bees.

Thinking about God often leads to thinking about ‘God’. And it has never been completely clear how best to understand this little English word. Traditionally, ‘God’ has been taken to be either a description or a name. However, a third option has recently captured the attention of philosophical theologians. It is claimed that just as one should think of, say, ‘humanity’ as a kind term, so one should think of ‘God’, or perhaps ‘divinity’, as a kind term. But given the (...) tight link between semantics and metaphysics, if one is tempted to understand ‘humanity’ or ‘divinity’ as kind terms, then one will naturally begin to think of humanity and divinity as kinds. Characterizing divinity this way, a primary task of philosophical theology is to give a characterization of the divine kind-essence. In this paper, I want to consider the claim that divinity is profitably construed as a kind-essence, and argue that the way that this has typically been understood is not altogether adequate. I shall then present and develop an alternative understanding of this kind-essence approach that takes the analogy of `supernatural kinds’ and natural kinds much more seriously. I will conclude by considering some objections. (shrink)

In this paper I argue that internalistic foundationalist theories of the justification of memory belief are inadequate. Taking a discussion of John Pollock as a starting point, I argue against any theory that requires a memory belief to be based on a phenomenal state in order to be justified. I then consider another version of internalistic foundationalism and claim that it, too, is open to important objections. Finally, I note that both varieties of foundationalism fail to account for the epistemic (...) status of our justified nonoccurrent beliefs, and hence are drastically incomplete. (shrink)

Detection theory has been applied to a host of varied problems (for example, measuring the accuracy of diagnostic systems or reliability of lie detection tests) and extends far beyond the detection of signals. This book is a primer on the subject.

In this clear and up-to-date introduction, Thomas D. Senor lays the philosophical foundation needed to understand the justification of memory belief. This book explores traditional accounts of the justification of memory belief and examines the resources that prominent positions in contemporary epistemology have to offer theories of the memorial justification. Along the way, epistemic conservatism, evidentialism, foundationalism, phenomenal conservatism, reliabilism, and preservationism all feature. Study Questions and annotated Further Reading guides at the end of each chapter make this book (...) ideal for classroom use and independent study. Written in very clear prose, A Critical Introduction to the Epistemology of Memory is a valuable resource for students approaching epistemology for the first time or those looking to advance their understanding of a core area of philosophy.

In his recent book, Jaegwon Kim argues thatpsychophysical supervenience withoutpsychophysical reduction renders mentalcausation `unintelligible'. He also claimsthat, contrary to popular opinion, his argumentagainst supervenient mental causation cannot begeneralized so as to threaten the causalefficacy of other `higher-level' properties:e.g., the properties of special sciences likebiology. In this paper, I argue that none ofthe considerations Kim advances are sufficientto keep the supervenience argument fromgeneralizing to all higher-level properties,and that Kim's position in fact entails thatonly the properties of fundamental physicalparticles are causally efficacious.

Self-control has been described as the ability to master motivation that is contrary to one’s better judgement; that is, an ability that prevents such motivation from resulting in behaviour that is contrary to one’s overall better judgement (Mele, Irrationality: An essay on Akrasia, self-deception and self-control, p. 54, 1987). Recent discussions in philosophy have centred on the question of whether synchronic self-control, in which one exercises self-control whilst one is currently experiencing opposing motivation, is actional or non-actional. The actional theorist (...) maintains that such exercises are actions, whilst the non-actional theorist claims that synchronic self-control consists in the having of unmotivated thoughts which occur at times when agents experience recalcitrant motivations and which serve to attenuate the strength of those motivations. In this paper I discuss a class of cases which has been largely ignored in these discussions, cases which I argue are common synchronic self-control problems, but in which a lack of motivation is the characteristic symptom. I argue that such cases present problems for actional accounts and add some support to the non-actional approach. (shrink)

It is often presumed by those who use propositions in their theories that propositions are representational; that is, that propositions represent the world as being some way. This paper makes two claims against this presumption. First, it argues that it does not follow from the fact that propositions play the theoretical roles usually attributed to them that they are representational. This conclusion is reached by rebutting three arguments that can be made in support of the claim that propositions are representational. (...) This paper then advances the further claim that propositions are not representational. It considers several ways to overcome the difficulties traditionally associated with this claim, particularly how to account for falsity. (shrink)

In a pair of recent articles, Brian Leftow and Eleonore Stump offer independent, although similar, accounts of the metaphysics of the Incarnation. Both believe that their Aquinas-inspired theories can offer solutions to the kind of Leibniz’s Law problems that can seem to threaten the logical possibility of this traditional Christian doctrine. In this paper, I’ll have a look at their compositional account of the nature of God incarnate. In the end, I believe their position can be seen to have unacceptable (...) philosophical and theological implications, and that is it inadequate to solve the Leibniz’s law problems that motivate it in the first place.

Philosophers and theologians acknowledge that "fideism" is difficult to define but rarely agree on what the best characterization of the term is. In this article, I investigate the history of use of "fideism" to explore why its meaning has been so contested and thus why it has not always been helpful for resolving philosophical problems. I trace the use of the term from its origins in French theology to its current uses in philosophy and theology, concluding that "fideism" is helpful (...) in resolving philosophical problems only when philosophers scrupulously acknowledge the tradition of use that informs their understanding of the word.

The term “euthanasia” is used in conflicting ways in the bioethical literature, as is the term “assisted suicide,” resulting in definitional confusion, ambiguities, and biases which are counterproductive to ethical and legal discourse. I aim to rectify this problem in two parts. Firstly, I explore a range of conflicting definitions and identify six disputed definitional factors, based on distinctions between (1) killing versus letting die, (2) fully intended versus partially intended versus merely foreseen deaths, (3) voluntary versus nonvoluntary versus involuntary (...) decisions, (4) terminally ill versus non-terminally ill patients, (5) patients who are fully conscious versus those in permanent comas or persistent vegetative states, and (6) patients who are suffering versus those who are not. Secondly, I distil these factors into six “building blocks” and combine them to develop an unambiguous, value-neutral taxonomy of “end-of-life practices.” I hope that this taxonomy provides much-needed clarification and a solid foundation for future ethical and legal discourse.

Father Williams explains how the conscience is formed through our training and experiences and informed by the Holy Spirit, making it an essential tool for daily living. He uses familiar and surprising characters to illustrate the positive choices conscience can direct--and the disaster that results when a conscience is undeveloped or ignored. Questions he tackles include "Is it more important to be smart or good?""Is there a morally right thing to do in every situation?" and "Is the Christian moral life (...) an exciting adventure, or a necessary burden?" Rich, provocative, and practical for everyday decision making, KNOWING RIGHT FROM WRONG is a must-read for all who hunger for personal holiness. (shrink)

In this paper I present and defend two arguments which purport to show that the doctrines of timelessness and the Incarnation are incompatible. An argument similar to the first argument I consider is briefly discussed by Stump and Kretzmann in their paper "Eternity." I argue that their treatment of this type of objection is inadequate. The second argument I present is, as far as I know, original; it depends on a certain subtlety in the doctrine of the Incarnation, viz., that (...) the Son took on or assumed a human nature. It seems that there is no way to understand what it is for the Son to take on a human nature that doesn’t entail his mutability; and mutability entails temporality. Thus, since Christ is said to take on a human nature, an orthodox Christology must maintain that the Son is temporal. I conclude by considering whether the Son’s temporality entails the temporality of the Godhead. (shrink)

Most arguments about conscientious objections in medicine fail to capture the full scope and complexity of the concept before drawing conclusions about their permissibility in practice. Arguments favoring and disfavoring the accommodation of conscientious objections in practice tend to focus too narrowly on prima facie morally contentious treatments and religious claims of conscience, while further failing to address the possibility of moral perspectives changing over time. In this paper, I argue that standard reasons against permitting conscientious objections in practice—that their (...) permission may result in harm to patients, the idea that medical providers willingly enter into the medical field, and that conscientious objections stand contrary to medical professionalism—do not apply in all cases and that the medical field and health systems in which many physicians now practice should continue to tolerate conscientious objections in practice.

Our technologies are progressively developing into algorithmic devices that seamlessly interface with digital personhood. This text discusses the ways in which technology is increasingly becoming a part of personhood and the resulting ethical issues. It extends upon the framework for a brain-based cyberpsychology outlined by the author's earlier book Cyberpsychology and the Brain: The Interaction of Neuroscience and Affective Computing. Using this framework, Thomas D. Parsons investigates the ethical issues involved in cyberpsychology research and praxes, which emerge in algorithmically (...) coupled people and technologies. The ethical implications of these ideas are important as we consider the cognitive enhancements that can be afforded by our technologies. If people are intimately linked to their technologies, then removing or damaging the technology could be tantamount to a personal attack. On the other hand, algorithmic devices may threaten autonomy and privacy. This book reviews these and other issues. (shrink)

The New Demon World Objection claims that reliabilist accounts of justification are mistaken because there are justified empirical beliefs at demon worlds— worlds at which the subjects are systematically deceived by a Cartesian demon. In this paper, I defend strongly verific (but not necessarily reliabilist) accounts of justification by claiming that there are two ways to construct a theory of justification: by analyzing our ordinary concept of justification or by taking justification to be a theoretic term defined by its role (...) in the theory of knowledge. The former route is not promising because of the splintered nature of our ordinary concept of justification—or perhaps because there is no single such concept. On the other hand, if justification is defined by the role it plays in the theory of knowledge, then there is good reason to think that justification must be strongly truth-conductive since the term was introduced by Edmund Gettier to play the primary role in converting true belief into knowledge. And if that is right, then there will be no justified empirical belief at demon worlds. The real lesson of the demon world is then turned on its head: justification does not supervene on what one shares with one’s deceived doppelganger. (shrink)

Can an act harm someone—a future someone, someone who does not exist yet but will—if that person would never exist but for that very action? This is one question raised by the non-identity problem. Many would argue that the answer is No: an action harms someone only insofar as it is worse for her, and an action cannot be worse for someone if she would not exist without it. The first part of this paper contends that the plausibility of the (...) ‘no harm’ argument stems from an equivocation. The second half argues for an account of harm that is both causal and contrastive. Finally, the paper contends that the contrastive account disarms the no harm argument and furthermore neutralizes a related argument that has been problematic for some previously proposed solutions to the non-identity problem.

According to Eric Funkhouser, omnipotence and necessary moral perfection (what Funkhouser calls "impeccability") are not compatible. Funkhouser gives two arguments for this claim. In this paper, I argue that neither of Funkhouser's arguments is sound. The traditional theist can reasonably claim that, contra Funkhouser, (i) there is no possible being who possesses all of God's attributes sans impeccability, and (ii) the fact that there are things that God cannot do does not entail that God lacks omnipotence. Armed with (i) and (...) (ii), the theist has all that is needed to refute Funkhouser's arguments. (shrink)
