An infinite number of elastically colliding balls is considered in a classical, and then in a relativistic setting. Energy and momentum are not necessarily conserved globally, even though each collision does separately conserve them. This result holds in particular when the total mass of all the balls is finite, and even when the spatial extent and temporal duration of the process are also finite. Further, the process is shown to be indeterministic: there is an arbitrary parameter in the general solution (...) that corresponds to the injection of an arbitrary amount of energy (classically), or energy-momentum (relativistically), into the system at the point of accumulation of the locations of the balls. Specific examples are given that illustrate these counter-intuitive results, including one in which all the balls move with the same velocity after every collision has taken place. (shrink)

An actual infinity of colliding balls can be in a configuration in which the laws of mechanics lead to logical inconsistency. It is argued that one should therefore limit the domain of these laws to a finite, or only a potentially infinite number of elements. With this restriction indeterminism, energy nonconservation and creatio ex nihilo no longer occur. A numerical analysis of finite systems of colliding balls is given, and the asymptotic behaviour that corresponds to the potentially infinite system is (...) inferred. (shrink)

The prevailing “segregated model” for understanding clinical research sharply separates it from clinical care and subjects it to extensive regulations and guidelines. This approach is based on the fact that clinical research relies on procedures and methods—research biopsies, blinding, randomization, fixed treatment protocols, placebos—that pose risks and burdens to participants in order to collect data that might benefit all patients. Reliance on these methods raises the potential for exploitation and unfairness, and thus points to the need for independent ethical review (...) and more extensive informed consent. In contrast, it is widely assumed that clinical care does not raise these ethical concerns because it is designed to promote the best interests of individual patients. The segregation of clinical research from clinical care has been largely effective at protecting research participants. At the same time, this approach ignores the fact that several aspects of standard clinical care, such as clinician training and scheduling, also pose some risks and burdens to present patients for the benefit of all patients. We argue that recently proposed learning health care systems offer a way to address this concern, and better protect patients, by developing integrated review and consent procedures. Specifically, current approaches base the need for independent ethical review and more extensive informed consent on whether an activity is categorized as clinical research or clinical care. An ethically sounder approach, which could be incorporated into learning health care systems, would be to base the need for independent ethical review and more extensive informed consent on the extent to which an activity poses risks to present patients for the benefit of all patients.

PET studies in domains like vision and attention have been successful because the experiments are the product of highly articulated theories. In contrast, the results of PET studies investigating language processing are difficult to interpret. We suggest that this difficulty is due to the more tentative connection of these experiments with the insights of psycholinguistics and linguistic theory.

Conscious technology features in many Black Mirror episodes. For example, there are the cookies in White Christmas, the people uploaded into the San Junipero simulation, Robert Daly's digital copies of his coworkers in USS Callister, and the copy of Clayton Leigh that is exhibited in Black Museum. But would such pieces of technology really be conscious? Would they, for example, feel pain? And how could we tell? Is uploading or replicating someone's consciousness even possible? This chapter explores these questions and (...) discusses the ethical issues that are raised by consciousness technology. (shrink)

The Monty Hall Dilemma (MHD) is a two-step decision problem involving counterintuitive conditional probabilities. The first choice is made among three equally probable options, whereas the second choice takes place after the elimination of one of the non-selected options which does not hide the prize. Differing from most Bayesian problems, statistical information in the MHD has to be inferred, either by learning outcome probabilities or by reasoning from the presented sequence of events. This often leads to suboptimal decisions and erroneous (...) probability judgments. Specifically, decision makers commonly develop a wrong intuition that final probabilities are equally distributed, together with a preference for their first choice. Several studies have shown that repeated practice enhances sensitivity to the different reward probabilities, but does not facilitate correct Bayesian reasoning. However, modest improvements in probability judgments have been observed after guided explanations. To explain these dissociations, the present review focuses on two types of causes producing the observed biases: Emotional-based choice biases and cognitive limitations in understanding probabilistic information. Among the latter, we identify a crucial cause for the universal difficulty in overcoming the equiprobability illusion: Incomplete representation of prior and conditional probabilities. We conclude that repeated practice and/or high incentives can be effective for overcoming choice biases, but promoting an adequate partitioning of possibilities seems to be necessary for overcoming cognitive illusions and improving Bayesian reasoning.

Completed shortly before her death in 2019, _Tragedy and Philosophy. A Parallel History_ is the sum of Agnes Heller’s reflections on European history and culture, seen through the prism of Europe’s two unique literary creations: tragedy and philosophy.

Property rights are important institutions that influence economic performance and reflect the historical, cultural, and political realities of particular societies. Drawing on a variety of concepts from legal and economic studies, a framework for explaining the origin and evolution of property rights is developed and applied to the specific case of changing ground water rights in Nebraska. The Nebraska case is an interesting example of reliance on local control in regulating water use. Despite the importance of local initiatives in ground (...) water management, this case also illustrates the need for external support from the judicial and legislative systems. The evolution of ground water property rights in Nebraska, as in other parts of the United States, has been conditioned by historical circumstances and changing values and attitudes as well as by economic and political forces.

The understanding of decision-making systems has come together in recent years to form a unified theory of decision-making in the mammalian brain as arising from multiple, interacting systems (a planning system, a habit system, and a situation-recognition system). This unified decision-making system has multiple potential access points through which it can be driven to make maladaptive choices, particularly choices that entail seeking of certain drugs or behaviors. We identify 10 key vulnerabilities in the system: (1) moving away from homeostasis, (2) (...) changing allostatic set points, (3) euphorigenic signals, (4) overvaluation in the planning system, (5) incorrect search of situation-action-outcome relationships, (6) misclassification of situations, (7) overvaluation in the habit system, (8) a mismatch in the balance of the two decision systems, (9) over-fast discounting processes, and (10) changed learning rates. These vulnerabilities provide a taxonomy of potential problems with decision-making systems. Although each vulnerability can drive an agent to return to the addictive choice, each vulnerability also implies a characteristic symptomology. Different drugs, different behaviors, and different individuals are likely to access different vulnerabilities. This has implications for an individual's susceptibility to addiction and the transition to addiction, for the potential for relapse, and for the potential for treatment. (shrink)

Contrary to what many philosophers believe, Calvinism neither makes the problem of evil worse nor is it obviously refuted by the presence of evil and suffering in our world. Or so most of the authors in this book claim. While Calvinism has enjoyed a resurgence in recent years amongst theologians and laypersons, many philosophers have yet to follow suit. The reason seems fairly clear: Calvinism, many think, cannot handle the problem of evil with the same kind of plausibility as other (...) more popular views of the nature of God and the nature of God's relationship with His creation. This book seeks to challenge that untested assumption. With clarity and rigor, this collection of essays seeks to fill a significant hole in the literature on the problem of evil. (shrink)

Although research has found that long-term mindfulness meditation practice promotes executive functioning and the ability to sustain attention, the effects of brief mindfulness meditation training have not been fully explored. We examined whether brief meditation training affects cognition and mood when compared to an active control group. After four sessions of either meditation training or listening to a recorded book, participants with no prior meditation experience were assessed with measures of mood, verbal fluency, visual coding, and working memory. Both interventions (...) were effective at improving mood but only brief meditation training reduced fatigue, anxiety, and increased mindfulness. Moreover, brief mindfulness training significantly improved visuo-spatial processing, working memory, and executive functioning. Our findings suggest that 4 days of meditation training can enhance the ability to sustain attention; benefits that have previously been reported with long-term meditators. (shrink)

Acculturation is the process through which an individual's cultural behaviors and values change via contact with a majority or host culture. Although some individuals accomplish acculturation smoothly, most experience psychological stress during the acculturation process. When psychologists encounter individuals struggling to acculturate, they are mandated by ethical guidelines and principles to help through several steps: (a) recognize their own biases, beliefs, and attitudes that may influence their work with the acculturating individual; (b) develop competence to work with individuals whose cultural (...) beliefs and practices differ from their own; (c) counsel the acculturating individual using scientifically supported techniques; and (d) intervene without discrimination or disrespect. Two case studies are presented to illustrate how psychologists can ethically and effectively encourage mentally healthy acculturation. Keywords: acculturation, ethics, cultural differences. (shrink)

Understanding the mechanisms of early embryonic patterning and the timely allocation of specific cells to embryonic regions and fates as well as their development into tissues and organs, is a fundamental problem in Developmental Biology. The classical explanation for this process had been built around the notion of positional information. Accordingly the programmed appearance of sources of Morphogens at localized positions within a field of cells directs their differentiation. Recently, the development of organs and tissues from unpatterned and initially identical (...) stem cells (adult and embryonic) has challenged the need for positional information and even the integrity of the embryo, for pattern formation. Here we review the emerging area of organoid biology from the perspective of Developmental Biology. We argue that the events underlying the development of these systems are not purely linked to “self‐organization,” as often suggested, but rather to a process of genetically encoded self‐assembly where genetic programs encode and control the emergence of biological structures.

The focus on translational research in clinical trials has the potential to generate clinically relevant genetic data that could have importance to patients. This raises challenging questions about communicating relevant genetic research results to individual patients. An exploratory pharmacogenetic analysis was conducted in the international ovarian cancer phase III trial, AGO-OVAR 16, which found that patients with clinically important germ-line BRCA1/2 mutations had improved progression-free survival prognosis. Mechanisms to communicate BRCA results were evaluated, because these findings may be beneficial to (...) patients and their families. Communicating individual BRCA results was not anticipated during clinical trial design. Consequently, options were not available for patients to indicate their preference for receiving their individual results when they signed pharmacogenetic informed consent. Differences in local requirements, clinical practice, and opinion regarding the ethical aspects of how to convey genetic results to patients are all potential barriers to returning individual BRCA results to patients. Communicating the aggregate BRCA result from this study provided clinical investigators with a mechanism to disseminate the overall study finding to patients while taking individual circumstances, local guidelines and clinical practice into account. This study illustrates the importance of increasing the clarity and scope of informed consent and the need for patient engagement to ensure clinical trial participants can indicate their preference regarding receipt of potentially important individual pharmacogenetic results. This study was registered in the NCT Clinical Trial Registry under NCT00866697 on March 19, 2009, following approval from participating ethics committees. (shrink)

The orphaned son of an Anglican clergyman, David Hartley (1705–57) was originally destined for holy orders. Declining to subscribe to the Thirty-Nine Articles, he turned to medicine and science yet remained a religious believer. This, his most significant work, provides a rigorous analysis of human nature, blending philosophy, psychology and theology. First published in two volumes in 1749, Observations on Man is notable for being based on the doctrine of the association of ideas. It greatly influenced scientists, theologians, social (...) reformers and poets: Samuel Taylor Coleridge, who named his eldest son after Hartley, had his portrait painted while holding a copy. In Volume 1, Hartley utilises Newtonian science in his observations, presenting his theory of 'vibrations'. Volume 2 is particularly concerned with human morality and the duty and expectations of mankind. Hartley is keen to show that scientific observation is not necessarily in conflict with religious conviction. (shrink)

We know little of her life prior to the events that removed her from the world of conscious, sentient beings.

For those who teach students in psychology, education, and the social sciences, the _Handbook of Demonstrations and Activities in the Teaching of Psychology, Second Edition_ provides practical applications and rich sources of ideas. Revised to include a wealth of new material, these invaluable reference books contain the collective experience of teachers who have successfully dealt with students' difficulty in mastering important concepts about human behavior. Each volume features a table that lists the articles and identifies the primary and secondary courses (...) in which readers can use each demonstration. Additionally, the subject index facilitates retrieval of articles according to topical headings, and the appendix notes the source as it originally appeared in _Teaching of Psychology_, the official journal of the Society for the Teaching of Psychology, Division Two of the American Psychological Association. Volume I consists of 97 articles about strategies for teaching introductory psychology, statistics, research methods, and the history of psychology classes. Divided into four sections, the book suggests ways to stimulate interest, promote participation, grasp psychological terminology, and master necessary scientific skills. (shrink)

[Open access] In this book symposium the author takes up questions from phenomenology, hermeneutics, ethical theory, and intellectual history raised by a group of scholarly interlocutors from a range of backgrounds. In the course of engaging with these issues, he discusses, inter alia, McDowell’s realism, Jonathon Lear’s work on the end of a world, Michael Oakeshott’s view of selfhood, Heidegger’s conception of Jemeinigkeit, Uexküll’s notion of Umwelt, and Gadamer’s hermeneutic conception of truth.

The psychedelic psilocybin has shown promise both as treatment for psychiatric conditions and as a means of improving well-being in healthy individuals. In some jurisdictions (e.g., Oregon, USA), psilocybin use for both purposes is or will soon be allowed and yet, public attitudes toward this shift are understudied. We asked a nationally representative sample of 795 US Americans to evaluate the moral status of psilocybin use in an appropriately licensed setting for either treatment of a psychiatric condition or well-being enhancement. (...) Showing strong bipartisan support, participants rated the individual’s decision as morally positive in both contexts. These results can inform effective policy-making decisions around supervised psilocybin use, given robust public attitudes as elicited in the context of an innovative regulatory model. We did not explore attitudes to psilocybin use in unsupervised or non-licensed community or social settings. (shrink)

In this paper, a novel efficient algorithm is presented for locating and tracking object parts in low resolution videos using Lowe's SIFT keypoints with a nearest neighbor object detection approach. Our interest lies in using this information as one step in the process of automatically programming service, household, or personal robots to perform the skills that are being taught in easily obtainable instructional videos. In the reported experiments, the system looked for 14 parts of inanimate and animate objects in 40 (...) natural outdoor scenes. The scenes were frames from a low-resolution instructional video on cleaning golf clubs containing 2,405 frames of 180 by 240 pixels. The system was trained using 39 frames that were half-way between the test frames. Despite the low resolution quality of the instructional video and occluded training samples, the system achieved a recall of 49% with a precision of 71% and an F1 of 0.58, which is better than that achieved by less demanding applications. In order to verify that the reported results were not dependent on the specific video, the proposed technique was applied to another video and the results are reported. (shrink)

"In the first study of its kind, David W. Johnson's "Watsuji on Nature" reconstructs the astonishing philosophy of nature of Watsuji Tetsurō (1889-1960), situating it in relation both to his reception of the thought of Heidegger and to his renewal of core ontological positions in classical Confucian and Buddhist philosophy. Johnson shows that for Watsuji we have our being in the lived experience of nature, one in which nature and culture compose a tightly interwoven texture called "fūdo". (...) By fully unfolding Watsuji's novel and radical claim that this is a setting that is neither fully external to human subjectivity nor merely a product of it, this book also sets out what still remains unthought in this concept, as well as in the relational structure that underwrites it. Johnson argues that what remains unarticulated is nothing less than the recovery of a reenchanted conception of nature and an elucidation of the wide-ranging implications of a relational conception of the self for questions about the disclosive character of experience, the distinction between fact and value, and the possibility of a place-based ecological ethics. In an engagingly lucid and deft analysis, "Watsuji on Nature" radically expands our appreciation of twentieth-century Japanese philosophy and shows what it has to offer to a global philosophical conversation"--Provided by publisher.

We present a rendering of some common grammatical formalisms in terms of evolving algebras. Though our main concern in this paper is on constraint-based formalisms, we also discuss the more basic case of context-free grammars. Our aim throughout is to highlight the use of evolving algebras as a specification tool to obtain grammar formalisms.

This paper attempts to reconcile two ideas that seem fundamentally opposed to one another: the reality of the self and the doctrine of no-self. Buddhism offers a form of spiritual equanimity that turns on the denial of a self. Nonetheless, there seem to be good reasons to hold onto the reality of the self. The existence of a self enables us to account for praise and blame, the hopes for oneself that motivate actions, and attachments to the selves of others (...) in bonds of love and affection. I show how it may be possible to reconcile the reality of the self with a particular interpretation of the no-self doctrine by engaging with the work of thinkers from the phenomenological tradition such as Merleau-Ponty, Zahavi, Gallagher, and Petitmengin.

Xenophon's Socratic Works demonstrates that Xenophon, a student of Socrates, military man, and man of letters, is an indispensable source for our understanding of the life and philosophy of Socrates. David M. Johnson restores Xenophon's most ambitious Socratic work, the Memorabilia, to its original literary context, enabling readers to experience it as Xenophon's original audience would have, rather than as a pale imitation of Platonic dialogue. He shows that the Memorabilia, together with Xenophon's Apology, provides us with our (...) best evidence for the trial of Socrates, and a comprehensive and convincing refutation of the historical charges against Socrates. Johnson's account of Socrates' moral psychology shows how Xenophon's emphasis on control of the passions can be reconciled with the intellectualism normally attributed to Socrates. Chapters on Xenophon's Symposium and Oeconomicus reveal how Xenophon used all the literary tools of Socratic dialogue to defend Socratic sexual morality and debate the merits and limits of conventional elite values. Throughout the book, Johnson argues that Xenophon's portrait of Socrates is rich and coherent, and largely compatible with the better-known portrait of Socrates in Plato. Xenophon aimed not to provide a rival portrait of Socrates, Johnson shows, but to supplement and clarify what others had said about Socrates. Xenophon's Socratic Works thus provides readers with a far firmer basis for reconstruction of the trial of Socrates, a key moment in the history of Athenian democracy, and for our understanding of Socrates' seminal impact on Greek philosophy. This volume introduces Xenophon's Socratic works to a wide range of readers, from undergraduate students encountering Socrates or ancient philosophy for the first time to scholars with interests in Socrates or ancient philosophy more broadly. It is also an important resource for readers interested in Socratic dialogue as a literary form, the trial of Socrates, Greek sexual morality, or Greek social history. (shrink)

This article explores political discourse in the context of an online-mediated 2021 rapprochement between Swedish ‘mainstream’ and far-right parties paving the way for their eventual 2022 electoral success and later joint government coalition. The article analyses specifically how the above political accord on the Swedish right – often seen as breaking the long-term cordon sanitaire around Sweden’s far right – would be legitimised via discourses that carried significant elaboration and deepening of the ‘criminality’ and ‘immigration’ connection later recontextualised into the (...) broader Swedish public discourse and public imagination. Using social media analytics and qualitative, critical discourse analysis, we explore in depth a ‘discursive shift’ wherein the focus on criminality would become a key ‘proxy discourse’, i.e., a public-wide implicature, which, while referring to and debating a potentially genuine social issue would be strategically instrumentalised to effectively pre-legitimise ‘moral panics’ around immigration and cultural diversity. The analysis highlights that the emergence as well as the later recontextualisation of the ‘proxy discourse’ in question – implicitly suggesting that criminality, immigration, and cultural diversity are ‘somehow’ inherently connected – not only supported the political mainstreaming of the Swedish far-right’s anti-immigration stance but also normalised the wider tenets of illiberal, nativist ‘politics of exclusion’.

In a recent book and article, James Sterba has argued that there is no free will defense. It is the purpose of this article to show that, in the most technical sense, he is wrong. There is a version of the free will defense that can solve what Sterba (rightly) takes to be the most interesting and severe version of the logical problem of moral evil. However, I will also argue that, in effect (or, we might say, in practice), Sterba (...) is correct. The only working version of the free will defense requires embracing a view that entails consequences theists traditionally have not and cannot accept. Consequently, the one and only free will solution is not viable. Unless some other solution can be found (Sterba argues there is none), the logical problem of evil, as Sterba understands it, either commits one to atheism, or a version of theism that practically all theists would regard as a heresy.

Conviction Narrative Theory (CNT) is a theory of choice underradical uncertainty– situations where outcomes cannot be enumerated and probabilities cannot be assigned. Whereas most theories of choice assume that people rely on (potentially biased) probabilistic judgments, such theories cannot account for adaptive decision-making when probabilities cannot be assigned. CNT proposes that people usenarratives– structured representations of causal, temporal, analogical, and valence relationships – rather than probabilities, as the currency of thought that unifies our sense-making and decision-making faculties. According to CNT, (...) narratives arise from the interplay between individual cognition and the social environment, with reasoners adopting a narrative that feels “right” to explain the available data; using that narrative to imagine plausible futures; and affectively evaluating those imagined futures to make a choice. Evidence from many areas of the cognitive, behavioral, and social sciences supports this basic model, including lab experiments, interview studies, and econometric analyses. We identify 12 propositions to explain how the mental representations (narratives) interact with four inter-related processes (explanation, simulation, affective evaluation, and communication), examining the theoretical and empirical basis for each. We conclude by discussing how CNT can provide a common vocabulary for researchers studying everyday choices across areas of the decision sciences. (shrink)

Entrepreneurs of contested commodities often face stakeholders engaged in market excluding boundary work driven by ethical considerations. For example, the conversion of academic scientific knowledge into technologies that can be owned and sold is a growing global trend and key stakeholders have different ethical responses to this contested commodity. Commercialization of science can be viewed as a good thing because people believe it bolsters economic growth and broadly benefits society. Others view it as bad because they believe it discourages basic (...) research that ought to be freely shared without concern for profit. Taking a descriptive sociological approach, we posit that the stance of a religious tradition toward capitalism will help shape individual scientists’ views on science commercialization and test whether the religious tradition of scientists correlates with their attitude toward the commercialization of science. To maximize variance on the religious tradition dimension, we analyze pooled data from a cross-national survey of university biologists and physicists encompassing France, Hong Kong, India, Italy, Taiwan, Turkey, UK and the USA. We indeed find religious tradition differences. Hindus and scientists with no religious tradition are more likely to agree that commercialization of science “harms a university’s commitment to knowledge production” than Protestants. We end with a discussion on business ethics and the moral limits of the market as well as implications for entrepreneurs of contested commodities. (shrink)

Until quite recently, mind-body dualism has been regarded with deep suspicion by both philosophers and scientists. This has largely been due to the widespread identification of dualism in general with one particular version of it: the interactionist substance dualism of Réné Descartes. This traditional form of dualism has, ever since its first formulation in the seventeenth century, attracted numerous philosophical objections and is now almost universally rejected in scientific circles as empirically inadequate. During the last few years, however, renewed attention (...) has begun to be paid to the dualistic point of view, as a result of increasing discontent with the prevailing materialism and reductionism of contemporary scientific and philosophical thought. Awareness has grown that dualism need not be restricted to its traditional form and that other varieties of dualism are not subject to the difficulties commonly raised against Descartes' own version of it. -/- Interest in these alternative versions of dualism is growing fast today, because it seems that they are capable of capturing deep-seated philosophical intuitions, while also being fully consistent with the methodological assumptions and empirical findings of modern scientific work on the human mind and brain. The object of this book is to provide philosophers, scientists, their students, and the wider general public with an up-to-date overview of current developments in dualistic conceptions of the mind in contemporary philosophy and science.

In C. S.

I show that Reppert’s argument fails for three reasons. (1) It “loads the die” by falsely assuming that naturalism, by definition, can't include mental causation "on the basic level." (I provide multiple examples of naturalist theories of (...) mind that do exactly that). (2) Physical processes can reliably produce true beliefs. And (3) reasoning isn’t necessarily mental.

Disagreements about abortion are often assumed to reduce to disagreements about fetal personhood (and mindedness). If one believes a fetus is a person (or has a mind), then they are “pro-life.” If one believes a fetus is not a person (or is not minded), they are “pro-choice.” The issue, however, is much more complicated. Not only is it not dichotomous—most everyone believes that abortion is permissible in some circumstances (e.g. to save the mother’s life) and not others (e.g. at nine (...) months of a planned pregnancy)—but scholars on both sides of the issue (e.g. Don Marquis and Judith Thomson) have convincingly argued that fetal personhood (and mindedness) are irrelevant to the debate. To determine the extent to which they are right, this article will define “personhood,” its relationship to mindedness, and explore what science has revealed about the mind before exploring the relevance of both to questions of abortion’s morality and legality. In general, this article does not endorse a particular answer to these questions, but the article should enhance the reader’s ability to develop their own answers in a much more informed way.

Some theists maintain that they need not answer the threat posed to theistic belief by natural evil; they have reason enough to believe that God exists and it renders impotent any threat that natural evil poses to theism. Explicating how God and natural evil coexist is not necessary since they already know both exist. I will argue that, even granting theists the knowledge they claim, this does not leave them in an agreeable position. It commits the theist to a very (...) unpalatable position: our universe was not designed by God and is instead, most likely, a computer simulation. (shrink)

Christian apologists, like Willian Lane Craig and Stephen T. Davis, argue that belief in Jesus’ resurrection is reasonable because it provides the best explanation of the available evidence. In this article, I refute that thesis. To do so, I lay out how the logic of inference to the best explanation (IBE) operates, including what good explanations must be and do by definition, and then apply IBE to the issue at hand. Multiple explanations—including (what I will call) The Resurrection Hypothesis, The (...) Lie Hypothesis, The Coma Hypothesis, The Imposter Hypothesis, and The Legend Hypothesis—will be considered. While I will not attempt to rank them all from worst to best, what I will reveal is how and why The Legend Hypothesis is unquestionably the best explanation, and The Resurrection Hypothesis is undeniably the worst. Consequently, not only is Craig and Davis’ conclusion mistaken, but belief in the literal resurrection of Jesus is irrational. In presenting this argument, I do not take myself to be breaking new ground; Robert Cavin and Carlos Colombetti have already presented a Bayesian refutation of Craig and Davis’ arguments. But I do take myself to be presenting an argument that the average person (and philosopher) can follow. It is my goal for the average person (and philosopher) to be able to clearly understand how and why the hypothesis “God supernaturally raised Jesus from the dead” fails utterly as an explanation of the evidence that Christian apologist cite for Jesus’ resurrection.
