Does natural selection favor veridical percepts—those that accurately depict objective reality? Perceptual and cognitive scientists standardly claim that it does. Here we formalize this claim using the tools of evolutionary game theory and Bayesian decision theory. We state and prove the “Fitness-Beats-Truth Theorem” which shows that the claim is false: If one starts with the assumption that perception involves inference to states of the objective world, then the FBT Theorem shows that a strategy that simply seeks to maximize expected-fitness payoff, (...) with no attempt to estimate the “true” world state, does consistently better. More precisely, the FBT Theorem provides a quantitative measure of the extent to which the fitness-only strategy dominates the truth strategy, and of how this dominance increases with the size of the perceptual space. The FBT Theorem supports the Interface Theory of Perception, which proposes that our perceptual systems have evolved to provide a species-specific interface to guide adaptive behavior, and not to provide a veridical representation of objective reality.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

Quentin Tarantino’s filmography, especially since the turn of the century, seems to be an argument for the moral justification of revenge. Bill and his D.iV.A.S. hit-squad (from Kill Bill); Adolf Hitler and Hans Landa (from Inglourious Basterds); “Monsieur” Calvin Candie and his loyal house slave Stephen (from Django Unchained); Stuntman Mike and the Manson family killers (from Death Proof and Once Upon a Time in Hollywood); and Daisy Domergue and General Sanford Smithers (from The Hateful Eight) – they all had (...) it coming, and audiences celebrate when they get what they deserve. Revenge, Tarantino reminds us, is a dish best served cold. But is it really the kind of thing that can be morally justified? To see whether it is, this chapter explores arguments both historic and contemporary. After delineating revenge from legal justice and simple retribution and exploring how Tarantino’s films argue for moral justification of revenge, we will consider common everyday arguments on the topic, as well as the relevant arguments of Plato, Baruch Spinoza, Thomas Hobbes, John Locke, Friedrich Nietzsche, Trudy Govier, Suzanne Uniacke, Andrew Oldenquist, Simone de Beauvoir, Joshua Gert, Gilead Bar-elli, David Heyd, Robert Nozick, and others. In the end, we will see that revenge can be justified – but only in very specific conditions. (shrink)

This book provides both a short history of Christian ethics and looks at itsbasic sources as they arise from Judaism, Greco-Roman ethics, andChristianity.

In this theological tour de force D. Stephen Long addresses a key question in current theological debate: the conditions of the possibility of God-talk, along ...

Forty years of avid bicycling came to a conclusion for D. Stephen Long in early October, 2020. Fearing his own imminent death required Long to reflect on life, on its beginnings, middle, and endings. This work uses the lessons learned from cycling, and the experience of the rapid onset of illness, to discuss God, friendship, racism, sexuality, justice, virtues, vices, and much more. It offers a moral theology but one more in keeping with how we take it up--not through theories (...) but in the practices that make up everyday life. Attention to everyday life can help us live well and in so doing prepare us to die well. " -- Publisher description. (shrink)

This article aims to reduce the polarization that has characterized discussion of memory work in psychotherapy. First, the article attempts to help critics of memory work understand the cultural and historical context in which their arguments have been received by practitioners and victim advocates: There are good reasons why attacks on memory work have been viewed with suspicion. Second, the article tries to convince practitioners and victim advocates that there nonetheless are legitimate grounds for concern about some forms of memory (...) work. The goal here is to persuade practitioners whose work includes a focus on childhood trauma to be cautious in their use of memory recovery techniques, without undermining support for survivors of childhood sexual abuse.

Should Christian ethics be an ecclesial or a nationalist project? This book addresses this question by tracing the development of an Augustinian and ecclesial approach to Christian ethics, noting the critiques the former brings against the latter, and assessing their merits.

William Abraham seeks to free Western Christianity from its epistemological captivity, at least as that captivity takes the form of a “criterion” that seeks certainty. To do so, he has developed “canonical theism,” an intriguing argument that draws on diverse means of grace for knowledge of God as justified belief. In Crossing the Threshold he gives us the epistemology for that project. Yet questions remains as to why it still needs an epistemology, why knowledge remains justified belief, and why it (...) cannot find more allies in other contemporary theological sensibilities.

This book addresses what it means to teach and learn ethics. While teaching ethics is universally applauded, how one goes about it is much more difficult and contested than is often recognized. The approach of the work is historical, philosophical, and theological. It begins with the historical transformation in the mid nineteenth century by Henry Sidgwick, who rejected establishing ethics on theology or metaphysics. G. E. Moore, John Rawls, Thomas Hurka, Bart Schultz, and Peter Singer later explicitly developed ethics indebted (...) to Sidgwick. However, G. E. M. Anscombe and Philippa Foot's important interventions in modern moral philosophy opened new possibilities for teaching and learning ethics that bear strong resemblances to pre-Sidgwick moral philosophy. The common thread between them is Thomas Aquinas, who had a different understanding of human action than Sidgwick. For Aquinas, Foot, and Anscombe, ethics does not concern a procedure to guide action to what is right or what ought to be, but exists within a metaphysical and theological realm in which the good is more basic than the right. The good is attractive so desire for it is an essential element of the moral life. (shrink)

“Canonical coherence” is necessary for reading, hearing and interpreting any text. It is not only something for which a theological interpreter of Scripture should aim, but also something that every interpreter of Scripture assumes. Irenaeus recognized that sources function as canons authorizing diverse readings. This essay assumes the truth of his Source and reads it against other sources by which biblical scholars and theologians interpret Scripture. It uses Hebrews 4: 14‐16 to examine the “Source” found in Gnostic, anti‐Platonic and Apocalyptic (...) orderings of the Bible. (shrink)

The Routledge Companion to Christian Ethics brings together two different but related disciplines; the first is contemplative or theoretical, asking what are the beliefs or doctrines that characterize Christianity, whilst the second is practical, asking what are the ethical practices that attend its teachings. The movement between the theoretical and practical aspects is not, however, one way, as doctrine and life are mutually informing. In this comprehensive volume, leading scholars address key topics, problems and debates in this hotly debated topic (...) within a truly global context. Comprising over thirty-five chapters by a team of international contributors, the Handbook is divided into three parts based on the three persons of the Trinity: God the Father, God the Son, and God the Holy Spirit. Within these sections, cutting-edge issues are examined, including: God and genetics; War, peace and violence; White supremacy; Creation and sexuality; Digital ethics; Transgender studies; Climate change; Immigration and refugees. Adopting a practical approach that must consider new concerns that have arisen with recent social, political, and cultural shifts, The Routledge Companion to Christian Ethics is essential reading for students and researchers in Christian ethics, religious ethics and Christianity Studies. The Handbook will also be very useful for those in related fields, such as ethics and philosophy. (shrink)

The choice is clear: truth, justice, freedom or lies, injustice, bondage? The good life and a just society depend on truth telling, but perhaps we are more comfortable with lies and fake news? How can we recognize the truth when everyone does "what is right in their own eyes"? When we accept and expect lies, how is civil society possible? How can we decide what is true, good, and right? If everyone has their own moral compass, is there any compass (...) at all? This book addresses the skepticism about our capacity to know anything for sure and the inevitable consequences of moral relativism. The author says that skepticism and relativism cannot provide effective barriers against the drift by democracies into authoritarianism--characterized by the heavy use of state power to impose the culture of one kind of Me on us all. In the past religion provided a beacon of hope and as the bedrock for our society and its laws. Now, religion is confined to the private and often silent recesses of the person. How then can we speak of God, truth, power, and justice as a society? These are some of the questions that the book takes up. Long begins by saying that truth and freedom promote human flourishing and concludes by pointing us to how we can discern and practice truth telling as private citizens and as people of faith.

This essay argues that, for Thomas Aquinas, nature always points in the direction of Christ. Therefore, moral theologies that proceed by way of nature in order to move beyond the confines of confessional traditions fail to read Aquinas well. Because Jesus is the Second Person of the Trinity, the exemplar in whom all things are made, nature cannot be a more universal category than Christology. Karl Barth critiqued Roman Catholic moral theology for failing to honour this essential theological point, wrongly (...) attributing the error to Aquinas. However, many contemporary Catholic moral theologians have adopted the very understanding of nature Barth critiques, and are using Thomas to do so. This loses the ecumenical character of Aquinas’s work. (shrink)

Job motivation remains an area of concern among researchers due to the rising issues of poor or lack of motivation among workers. This refers to one’s personal will or drives to perform a task at work. Meanwhile, job satisfaction refers to an employee’s sense of fulfillment with his or her work experience. Therefore, the current study utilized the descriptive- correlational research design to investigate the impact of job motivation on the job satisfaction of accountants. To gather essential data and achieve (...) the objectives of the study, Multidimensional Work Motivational Scale (MWMS) and Minnesota Satisfaction Questionnaire (MSQ) were administered to the target respondents. The collected data were then analyzed using a Multiple Regression Analysis; findings revealed that job motivation has a significant impact on the job satisfaction of accountants. Additionally, the results of this study were carefully evaluated and discussed, and recommendations were made to benefit the stakeholders of the study and contribute to the existing body of knowledge.

Psychedelics such as psilocybin reliably produce significantly altered states of consciousness with a variety of subjectively experienced effects. These include certain changes to perception, cognition, and affect,1 which we refer to here as the acute subjective effects of psychedelics. In recent years, psychedelics such as psilocybin have also shown considerable promise as therapeutic agents when combined with talk therapy, for example, in the treatment of major depression or substance use disorder.2 However, it is currently unclear whether the aforementioned acute subjective (...) effects are necessary to bring about the observed therapeutic effects of psilocybin and other psychedelics. This uncertainty has sparked a lively—though still largely hypothetical—debate on whether psychedelics without subjective effects (“nonsubjective psychedelics” or “non-hallucinogenic psychedelics”) could still have the same therapeutic impact, or whether the acute subjective effects are in fact necessary for this impact to be fully realized.3,4,5.
