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.

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.

Insight problem solving is hindered by automated verbal–conceptual processes. Because mindfulness meditation training aims at “nonconceptual awareness” which involves a reduced influence of habitual verbal–conceptual processes on the interpretation of ongoing experience, mindfulness may facilitate insight problem solving. This hypothesis was examined across two studies . Participants in both studies completed a measure of trait mindfulness and a series of insight and noninsight problems. Further, participants in Study 2 completed measures of positive affect and a mindfulness or control training. The (...) results indicated that trait mindfulness predicts better insight but not noninsight problem solving , this relation is maintained when controlling for positive affect , mindfulness training improves insight but not noninsight problem solving and this improvement is partially mediated by state mindfulness . These findings are the first to document a direct relation between mindfulness and creativity. (shrink)

This paper distinguishes between epistemic and metaphysical problems of arbitrariness for vagueness. It argues that epistemicism can resolve the epistemic problem of arbitrariness but not the metaphysical one.

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)

Analysis of sites of newly integrated DNA in cellular genomes is important to several fields, but methods for analyzing and visualizing these datasets are still under development. Here, we describe tools for data analysis and visualization that take as input integration site data from our INSPIIRED pipeline. Paired-end sequencing allows inference of the numbers of transduced cells as well as the distributions of integration sites in target genomes. We present interactive heatmaps that allow comparison of distributions of integration sites to (...) genomic features and that support numerous user-defined statistical tests. To summarize integration site data from human gene therapy samples, we developed a reproducible report format that catalogs sample population structure, longitudinal dynamics, and integration frequency near cancer-associated genes. We also introduce a novel summary statistic, the UC50, which provides a single number summarizing possible clonal expansion. Using these tools, we characterize ongoing longitudinal characterization of a patient from the first trial to treat severe combined immunodeficiency-X1, showing successful reconstitution for 15 years accompanied by persistence of a cell clone with an integration site near the cancer-associated gene CCND2.

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.

Ethics isn’t a conversation exclusive to philosophers. There is value, then, in not only understanding how laypeople think about issues in ethics, but also bringing their judgments into dialogue with those of philosophers in order to make sense of agreement, disagreement, and the consequences of each. Experimental philosophers facilitate this dialogue uniquely by capturing laypeople’s judgments and analyzing them in light of philosophical theory. They have done so almost exclusively by using face valid quantitative surveys about philosophically interesting thought experiments. (...) Based on high participant support for this or that response, researchers conclude that a given theory is more or less intuitive, and in some cases that it is or isn’t true. However, such conclusions can only be drawn from quantitative survey data if one assumes those data accurately reflect laypeople’s thinking on the issues of interest, an assumption that can’t be justified by the quantitative data itself since they are potentially opaque. This is the methodological problem of experimental philosophy: experimental philosophers who use quantitative methods alone can’t sufficiently demonstrate their data to be reflective of relevant judgments/intuitions. To better explore people’s judgments on issues in ethics and to determine whether experimental philosophers are or aren’t getting what they take themselves to be getting in surveys, I recreated part of an experiment by Chituc, Henne, Sinnott-Armstrong, and De Brigard on the Kantian principle that “ought implies can”, or that whenever an agent ought to do something then it is the case that she can, and added a layer of qualitative data to it by having participants think aloud while completing the surveys and conduct a follow-up interview. With similar quantitative results to those from Chituc et al., I argue that my qualitative results 1) cast doubt on Chituc et al.’s data being reflective of many people’s judgments, especially on the more interesting questions relating to moral obligation; 2) reveal unique insights into how people think about OIC; 3) generally speak to the value of experimental philosophers using triangulation of methods in better understanding laypeople’s complex and varied thinking about questions important to ethics and beyond. Supplemental documents: Appendices A, B, C, D, and E are surveys I used in my study. Appendices C and D are derived from Chituc et al.’s publication “Blame, Not Ability, Impacts Moral ‘Ought’ Judgments for Impossible Actions: Toward an Empirical Refutation of ‘Ought’ Implies ‘Can.’” Appendix F is the recruitment flyer I distributed for my study. Appendix H is the quantitative data from my study. (shrink)

Ce texte offre un aperçu des articles composant ce numéro spécial et présente brièvement les principaux arguments avancés dansA Conceptual Investigation of Justice, dont une des thèses centrales veut qu’un important désaccord à la fois sémantique et philosophique sur la définition du terme «justice» soit au cœur de plusieurs questions en philosophie politique contemporaine. Cette présentation nous amène par ailleurs à décrire les caractéristiques d’un débat sémantique dont la portée dépasse la stricte sphère linguistique.

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)

'Middle Platonists' is a work that focuses on the period of intellectual activity which flourished from the time of the "dogmatist" Antiochus Aschalon (ca. 80 BC) to Ammonius Saccas (ca. 220 AD), the mysterious "teacher" of the great Plotinus.

Two hundred and fifty years ago in A. D. 1763, the learned and brilliant German philologist PETRUS WESSELING published in Amsterdam his magisterial edition of the Greek text of Herodotos. His text became very influential and was the basis of nearly all later editions, with his emendations and readings adopted without question over the coming decades and eventually centuries. Many of these were the product of his deep knowledge of Greek history. But at 1.64.3, WESSELING emended the reading of all (...) the best manuscripts from Ἀλκμεωνιδέω to Ἀλκμεωνιδέων. This emendation means that those who fled Attica after the Battle of Pallene in 546 B. C. went into exile with the Alkmeonidai, rather than with a specific individual, Alkmeonides. Yet this removal of Alkmeonides from Herodotos’ narrative at this point is neither necessary nor justifiable. (shrink)

Contrairement à la plupart des écrits néoplatoniciens sur Aristote, le commentaire de Syrianus sur les Livres M et N de la Métaphysique revêt un ton particulièrement polémique. Certes, il s’agit là peut-être d’une réaction prévisible au contenu fortement antiplatonicien de M et N, mais il n’en demeure pas moins que Syrianus choisit délibérément de commenter ces textes-là. À cette fin, il a recours à divers procédés de polémique rhétorique, qu’il manie avec grande habilité. La première stratégie consiste à traiter Aristote (...) avec condescendance, en lui exposant simplement, ainsi qu’à nous, la doctrine platonicienne véritable. Ailleurs, il l’affronte en échangeant sarcasme pour sarcasme. Cependant il lui arrive aussi de chercher à réfuter le Stagirite dans les termes mêmes de ce dernier, en citant Aristote contre Aristote. Je discute quelques exemples de ces trois procédés en les traitant l’un après l’autre puisque chacun présente un intérêt particulier. Je conclus toutefois que cette polémique ne signifie pas forcément que Syrianus rejette le consensus néoplatonicien sur l’accord fondamental entre Platon et Aristote. (shrink)
