In this paper I articulate and defend a new anti-theodicy challenge to Skeptical Theism. More specifically, I defend the Threshold Problem according to which there is a threshold to the kinds of evils that are in principle justifiable for God to permit, and certain instances of evil are beyond that threshold. I further argue that Skeptical Theism does not have the resources to adequately rebut the Threshold Problem. I argue for this claim by drawing a distinction between a weak and (...) strong version of Skeptical Theism, such that the strong version must be defended in order to rebut the Threshold Problem. However, the skeptical theist’s appeal to our limited cognitive faculties only supports the weak version. (shrink)

Given the recent explosion of interest in applications of evolutionary biology to understanding human psychology, we think it timely to assure better understanding of modern evolutionary theory among the psychologists who might be using it. We find it necessary to do so because of the very reducd version of evolutionary theorizing that has been incorporated into much of evolutionary psychology so far. Our aim here is to clarify why the use of a reduced version of evolutionary genetics will lead to (...) faulty science and to indicate where other resources of evolutionary biology can be found that might elevate the standard of the evolutionary component of evolutionary psychology.

The amount of biomedical research being conducted around the world has greatly expanded over the past 15 years, with particularly large growth occurring in low- and middle-income countries. This increased focus on understanding and responding to disease burdens around the world has brought forth a desire to help LMIC institutions enhance their own capacity to conduct scientifically and ethically sound research. In support of these goals the Johns Hopkins-Fogarty African Bioethics Training Program has, for the past six years, partnered with (...) three research institutions in Africa to support research ethics capacity. Each partnership began with a baseline evaluation of institutional research ethics environments in order to properly tailor capacity strengthening activities and help direct limited institutional resources. Through the course of these partnerships we have learned several lessons regarding the evaluation process and the framework used to complete the assessments. We believe that these lessons are generalizable and will be useful for groups conducting such assessments in the future. (shrink)

Overdiagnosis refers to diagnosis that does not benefit patients because the diagnosed condition is not a harmful disease in those individuals. Overdiagnosis has been identified as a problem in cancer screening, diseases such as chronic kidney disease and diabetes, and a range of mental illnesses including depression and attention deficit hyperactivity disorder. In this paper, we describe overdiagnosis, investigate reasons why it occurs, and propose two different types. Misclassification overdiagnosis arises because the diagnostic threshold for the disease in question has (...) been set at a level where many people without harmful disease are nonetheless diagnosed. We illustrate misclassification overdiagnosis using the example of chronic kidney disease. Misclassification occurs in diseases diagnosed using biomarkers or based on patient reported phenomena. Maldetection overdiagnosis arises because, at the time the diagnosis is made and despite the presence of a 'gold standard' diagnostic test, it is not possible to discriminate between harmful and non-harmful cases of the index disease. We illustrate maldetection overdiagnosis using the example of thyroid cancer. While there is some overlap between misclassification and maldetection overdiagnosis, this conceptual analysis helps to clarify the phenomenon of overdiagnosis and is a necessary first step in developing strategies to address the problem.

This paper presents a general computational treatment of how mammals are able to deal with visual objects and environments. The model tries to cover the entire range from behavior and phenomenological experience to detailed neural encodings in crude but computationally plausible reductive steps. The problems addressed include perceptual constancies, eye movements and the stable visual world, object descriptions, perceptual generalizations, and the representation of extrapersonal space.The entire development is based on an action-oriented notion of perception. The observer is assumed to (...) be continuously sampling the ambient light for information of current value. The central problem of vision is taken to be categorizing and locating objects in the environment. The critical step in this process is the linking of visual information to symbolic object descriptions; this is calledindexing, from the analogy of identifying a book from index terms. The system must also identifysituationsand use this knowledge to guide movement and other actions in the environment. The treatment focuses on the different representations of information used in the visual system.The four representational frames capture information in the following forms: retinotopic, head-based, symbolic, and allocentric. The functional roles of the four frames, the communication among them, and their suggested neurophysiological realization constitute the core of the paper. The model is perforce crude, but appears to be consistent with all relevant findings. (shrink)

Much of the progress in the fields constituting cognitive science has been based upon the use of explicit information processing models, almost exclusively patterned after conventional serial computers. An extension of these ideas to massively parallel, connectionist models appears to offer a number of advantages. After a preliminary discussion, this paper introduces a general connectionist model and considers how it might be used in cognitive science. Among the issues addressed are: stability and noise‐sensitivity, distributed decision‐making, time and sequence problems, and (...) the representation of complex concepts. (shrink)

Disagreement is common: even informed, intelligent, and generally reasonable people often come to different conclusions when confronted with what seems to be the same evidence. Can the competing conclusions be reasonable? If not, what can we reasonably think about the situation? This volume examines the epistemology of disagreement. Philosophical questions about disagreement arise in various areas, notably politics, ethics, aesthetics, and the philosophy of religion: but this will be the first book focusing on the general epistemic issues arising from informed (...) disagreement. Ten leading philosophers offer specially written essays which together will offer a starting-point for future work on this topic. (shrink)

This volume presents cutting-edge theory and research on emotions as constructed events rather than fixed, essential entities. It provides a thorough introduction to the assumptions, hypotheses, and scientific methods that embody psychological constructionist approaches. Leading scholars examine the neurobiological, cognitive/perceptual, and social processes that give rise to the experiences Western cultures call sadness, anger, fear, and so on. The book explores such compelling questions as how the brain creates emotional experiences, whether the "ingredients" of emotions also give rise to other (...) mental states, and how to define what is or is not an emotion. Introductory and concluding chapters by the editors identify key themes and controversies and compare psychological construction to other theories of emotion. (shrink)

Researchers have wondered how the brain creates emotions since the early days of psychological science. With a surge of studies in affective neuroscience in recent decades, scientists are poised to answer this question. In this target article, we present a meta-analytic summary of the neuroimaging literature on human emotion. We compare the locationist approach (i.e., the hypothesis that discrete emotion categories consistently and specifically correspond to distinct brain regions) with the psychological constructionist approach (i.e., the hypothesis that discrete emotion categories (...) are constructed of more general brain networks not specific to those categories) to better understand the brain basis of emotion. We review both locationist and psychological constructionist hypotheses of brain–emotion correspondence and report meta-analytic findings bearing on these hypotheses. Overall, we found little evidence that discrete emotion categories can be consistently and specifically localized to distinct brain regions. Instead, we found evidence that is consistent with a psychological constructionist approach to the mind: A set of interacting brain regions commonly involved in basic psychological operations of both an emotional and non-emotional nature are active during emotion experience and perception across a range of discrete emotion categories.

Most models of generational succession in sexually reproducing populations necessarily move back and forth between genic and genotypic spaces. We show that transitions between and within these spaces are usually hidden by unstated assumptions about processes in these spaces. We also examine a widely endorsed claim regarding the mathematical equivalence of kin-, group-, individual-, and allelic-selection models made by Lee Dugatkin and Kern Reeve. We show that the claimed mathematical equivalence of the models does not hold. *Received January 2007; revised (...)

In our response, we clarify important theoretical differences between basic emotion and psychological construction approaches. We evaluate the empirical status of the basic emotion approach, addressing whether it requires brain localization, whether localization can be observed with better analytic tools, and whether evidence for basic emotions exists in other types of measures. We then revisit the issue of whether the key hypotheses of psychological construction are supported by our meta-analytic findings. We close by elaborating on commentator suggestions for future research.

In most U.S. jurisdictions, clinicians providing informal “curbside” consults are protected from medical malpractice liability due to the absence of a doctor-patient relationship. A recent Minnesota Supreme Court case, Warren v. Dinter, offers the opportunity to reassess whether the majority rule is truly serving the best interests of patients.

We focus on the recent non-causal theory of reasons explanationsof free action proffered by a proponent of the agency theory, Timothy O'Connor. We argue that the conditions O'Connor offersare neither necessary nor sufficient for a person to act for a reason. Finally, we note that the role O'Connor assigns toreasons in the etiology of actions results in further conceptual difficulties for agent-causalism.

Do our lives have meaning? Should we create more people? Is death bad? Should we commit suicide? Would it be better if we were immortal? Should we be optimistic or pessimistic? Life, Death, and Meaning brings together key readings, primarily by English-speaking philosophers, on such 'big questions.'.

What is death? Do people survive death? What do we mean when we say that someone is "dying"? Presenting a clear and engaging discussion of the classic philosophical questions surrounding death, this book studies the great metaphysical and moral problems of death. In the first part, Feldman shows that a definition of life is necessary before death can be defined. After exploring several of the most plausible accounts of the nature of life and demonstrating their failure, he goes on (...) to propose his own conceptual scheme for death and related concepts. In the second part, Feldman turns to ethical and value-theoretical questions about death. Addressing the ancient Epicurean ethical problem about the evil of death, he argues that death can be a great evil for those who die, even if they do not exist after death, because it may deprive them of the goods they would have enjoyed if they had continued to live. Confrontations with the Reaper concludes with a novel consequentialist theory about the morality of killing, applying it to such thorny practical issues as abortion, suicide, and euthanasia.

Wes Morriston contends that William Lane Craig's argument for the impossibility of a beginningless past results in an equally good argument for the impossibility of an endless future. Craig disagrees. I show that Craig's reply reveals a commitment to an unmotivated position concerning the relationship between actuality and the actual infinite. I then assess alternative routes to the impossibility of a beginningless past that have been offered in the literature, and show that, contrary to initial appearances, these routes similarly seem (...) to support the impossibility of an endless future.

I draw upon Helen Steward's concept of agential settling to argue that freedom requires an ability to change the truth‐value of tenseless future contingents over time from false to true and that this ability requires a metaphysically open future.

According to actualism, an agent ought to φ just in case what would happen if she were to φ is better than what would happen if she were to ~φ. We argue that actualism makes a morally irrelevant distinction between certain counterfactuals, given that an agent sometimes has the same kind of control over their truth-value. We then offer a substantive revision to actualism that avoids this morally irrelevant distinction by focusing on a certain kind of control that is available (...) to an agent. Finally, we show how this revised view has two additional advantages over actualism. (shrink)

Embodiment, the explicit dependence of cognition on the properties of the human body, is the foundation of contemporary cognitive science. Ballard et al.'s target article makes an important contribution to the embodiment story by suggesting how limitations on neural binding ability lead to deictic strategies for many tasks. It also exploits the powerful experimental method of instrumented virtual reality. This commentary suggests some ways in which the target article might be misinterpreted and offers other cautions.

Advances in behavioral and brain sciences have engendered wide ranging efforts to help understand consciousness. The target article suggests that abstract computational models are ill-advised. This commentary broadens the discussion to include mysteries of subjective experience that are inconsistent with current neuroscience. It also discusses progress being made through demystifying specific cases and pursuing evolutionary considerations.
