Harms and risks to groups and third-parties can be significant in the context of research, particularly in data-centric studies involving genomic, artificial intelligence, and/or machine learning technologies. This article explores whether and how United States federal regulations should be adapted to better align with current ethical thinking and protect group interests. Three aspects of the Common Rule deserve attention and reconsideration with respect to group interests: institutional review board (IRB) assessment of the risks/benefits of research; disclosure requirements in the informed (...) consent process; and criteria for waivers of informed consent. In accordance with respect for persons and communities, investigators and IRBs should systematically consider potential group harm when designing and reviewing protocols, respectively. Research participants should be informed about any potential group harm in the consent process. We call for additional public discussion, empirical research, and normative analysis on these issues to determine the right regulatory and policy path forward. (shrink)

Aquinas has been traditionally seen as the Christian thinker who was opposed to Platonism and predominantly influenced by the philosophy of Aristotle. In this study, Patrick Quinn argues that the most important aspects of Aquinas' theory of knowledge can only be properly understood when his Platonism is taken into account. Although he agreed with Aristotle that human knowledge is obtained from sensory-based experience, Thomas also insisted that the human mind functions at its best when it acts independently of (...) the senses. This occurs at the most sublime level when the mind is divinely enlightened when God's essence is made visible. (shrink)

This paper will examine some of the epistemological issues that emerge in the context of discussing the relationship between knowledge, control and power. These concerns raise questions about self-authenticating intuition and about who should control knowledge and how it should be disseminated. The importance of Plato as a key contributor to this debate will be discussed and it will be suggested that his writings provide a basic frame of reference for subsequent thinkers whose concerns also lie in this area. The (...) political importance of philosophy, the centrality of education, the use of language and the function of censorship are issues in Platonic epistemology that merit some discussion. The medieval views of Averroes, Maimonides and Aquinas will be examined for their contributions to the literature on this subject in the context of the respective theological frameworks, and something will be said about the implications of their conclusions for a theocratic society. Finally, I suggest that there is a need for a contemporary reappraisal of how an adequate balance between the individual's right to know and the socio-political implications of knowledge might be achieved.

Ludwig Wittgenstein’s and Bertrand Russell’s views on mysticism show their intense interest in this subject and how they explored its nature and possibilities. Wittgenstein, who had abandoned his Catholic faith as a teenager, became a religious searcher, which began from his fears of the terrors of war. He had enlisted as a soldier to fight for Austro-Hungary during which his terror of war led him to pray to God for refuge. The fortuitous discovery of Leo Tolstoy’s book, The Gospel in (...) Brief, opened Wittgenstein’s mind to the importance of Jesus and led him to value Christianity once more. Russell’s interest in mysticism appears in a published article written in 1914 and seems to have been one of curiosity, rather than religious. From a young age, Russell became extremely interested in mathematics and he came to perceive that this subject might be called mathematical mysticism. In both cases, Wittgenstein and Russell shared a keen interest in mysticism, with Wittgenstein concluding in his Tractatus that the mystical was transcendent while Russell chose to examine how mysticism and empiricism might complement each other.

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

In “Epistemology in Philosophy of Religion,” Philip Quinn focuses on the central problem of religious epistemology for monotheistic religions: the epistemic status of belief in the existence of God. He explores what epistemic conditions arguments for God's existence would have to satisfy to be successful and whether any arguments satisfy those conditions. Turning to the claims of reformed epistemology about belief in God, Quinn assesses Alvin Plantinga's claim that belief in God is for many theists properly basic, that (...) is, has positive epistemic status even when it is not based on arguments or any other kind of propositional evidence. Quinn distinguishes two versions of this claim. According to the first, emphasized in Plantinga's earlier work, theistic belief is properly basic with respect to justification or rationality, while according to the second version, prominent in Plantinga's more recent work, theistic belief is properly basic with respect to warrant.

At least since Aristotle’s famous 'sea-battle' passages in On Interpretation 9, some substantial minority of philosophers has been attracted to the doctrine of the open future--the doctrine that future contingent statements are not true. But, prima facie, such views seem inconsistent with the following intuition: if something has happened, then (looking back) it was the case that it would happen. How can it be that, looking forwards, it isn’t true that there will be a sea battle, while also being true (...) that, looking backwards, it was the case that there would be a sea battle? This tension forms, in large part, what might be called the problem of future contingents. A dominant trend in temporal logic and semantic theorizing about future contingents seeks to validate both intuitions. Theorists in this tradition--including some interpretations of Aristotle, but paradigmatically, Thomason (1970), as well as more recent developments in Belnap, et. al (2001) and MacFarlane (2003, 2014)--have argued that the apparent tension between the intuitions is in fact merely apparent. In short, such theorists seek to maintain both of the following two theses: (i) the open future: Future contingents are not true, and (ii) retro-closure: From the fact that something is true, it follows that it was the case that it would be true. It is well-known that reflection on the problem of future contingents has in many ways been inspired by importantly parallel issues regarding divine foreknowledge and indeterminism. In this paper, we take up this perspective, and ask what accepting both the open future and retro-closure predicts about omniscience. When we theorize about a perfect knower, we are theorizing about what an ideal agent ought to believe. Our contention is that there isn’t an acceptable view of ideally rational belief given the assumptions of the open future and retro-closure, and thus this casts doubt on the conjunction of those assumptions.

This chapter defends a divine command theory consisting of two central claims. First, a kind of action is morally obligatory just in case God has commanded that actions of that kind be performed. Second, God’s commanding that a kind of action be performed is what makes it obligatory. God’s commands bring it about that the wrong actions are wrong, and the required actions are required. Moreover, God’s goodness ensures that His commands are not arbitrary. God is the standard of Goodness. (...) Something is good just in case it resembles God in a relevant way. Since God resembles Himself, He is good, and His commands are suited to ground moral obligations. Deontic or duty-related properties depend on God’s commands, but axiological or evaluative properties, such as goodness, do not. (shrink)

In this paper I argue against three leading accounts of self-deception in the philosophical literature and propose a heretofore overlooked route to self-deception. The central problem with extant accounts of self-deception is that they are unable to balance two crucial desiderata: (1) to make the dynamics of self-deception (e.g., the formation of self-deceptive beliefs) psychologically plausible and (2) to capture self-deception as an intentional phenomenon for which the self-deceiver is responsible. I argue that the three leading views all fail on (...) one or both counts. However, I claim that many or most cases of self-deception conform to a different model, which I call ‘Self-deception as Omission’. In these cases, the process of self-deceptive belief formation and the intentional act for which the self-deceiver is responsible come apart, allowing us to meet both desiderata. Self-deceptive beliefs are often formed by unconscious mechanisms closely analogous to the 'System 1' processes of dual-systems psychology, or by other mechanisms of motivated reasoning. The nascently self-deceptive subject then acquiesces in the comforting belief and commits an epistemic failure by allowing it to persist. If this is done for motivationally biased reasons — e.g., preferring that the belief in question be true — then the subject is self-deceived and is blameworthy for her epistemic omission. (shrink)

The Polymath Project is an online collaborative enterprise that was initiated in 2009, when Timothy Gowers asked whether and how groups could work together to solve mathematical problems that “do not naturally split up into a vast number of subtasks.” Gowers proposed to answer this question himself by actually trying to set up such a collaboration, based on interactions taking place in the comment-threads of a series of posts on a WordPress blog. Hence, the first project officially started in early (...) 2009, to be proclaimed successful only 6 weeks later (Gowers and Nielsen 2009). From its inception until April 2018, 15 more Polymath problems (and a handful of smaller or related ones) have been launched. These projects have attracted attention from different scholarly communities, including the philosophy of mathematical practices, from the perspective of which the Polymath Project can be seen as a vast repository of mathematics in action. This chapter continues previous work by its authors on the topic in question and topics related. More specifically, for the purposes of this volume, it is our aim to both summarize and expand upon these earlier contributions. The starting point is the above observation that in the past decade, the issue of “massively collaborative mathematics” (to be qualified below) has drawn quite some attention. However, does it also warrant intensive philosophical attention in particular? For, as exciting as these developments might be from mathematical and other points of view, the enhanced possibilities that have come with it do not per se give rise to any philosophical import. In Van Bendegem (2011), one of us has indeed tentatively argued for the philosophical relevance of these new dynamics of proof construction flowing from the wide availability and efficiency of Internet technology. We shall below briefly rehearse and update the argument given there. (shrink)

The consideration of the problem of healthcare allocation as a special case of distributive justice is especially alluring when we only consider consequentialist theories. I articulate here an alternative Rawlsian non-consequentialist theory which prioritizes the fairness of healthcare allocation procedures rather than directly setting distributive parameters. The theory in question stems from Rawlsian commitments that, it is argued, have a better Rawlsian pedigree than those considered as such by Tännsjö. The alternative framework is worthy of consideration on its own merits, (...) but it also casts light on two related difficulties with Tännsjö’s approach: (i) the limits of his supposedly ecumenical methodology, which is revealed to be dialectically suspect and (ii) issues with the type of abstraction and idealization from actual judgements and preferences which the approach requires.

In this paper I argue that warrant for Lewis’ principle of recombination presupposes warrant for a combinatorial analysis of intrinsicality, which in turn presupposes warrant for the principle of recombination. This, I claim, leads to a vicious circularity: warrant for neither doctrine can get off the ground.

Major Depressive Disorder (MDD) is a serious condition with a large disease burden. It is often claimed that MDD is a “brain disease.” What would it mean for MDD to be a brain disease? I argue that the best interpretation of this claim is as offering a substantive empirical hypothesis about the causes of the syndrome of depression. This syndrome-causal conception of disease, combined with the idea that MDD is a disease of the brain, commits the brain disease conception of (...) MDD to the claim that brain dysfunction causes the symptoms of MDD. I argue that this consequence of the brain disease conception of MDD is false. It incorrectly rules out genuine instances of content-sensitive causation between adverse conditions in the world and the characteristic symptoms of MDD. Empirical evidence shows that the major causes of depression are genuinely psychological causes of the symptoms of MDD. This rules out, in many cases, the “brute” causation required by the brain disease conception. The existence of cases of MDD with non-brute causes supports the reinstatement of the old nosological distinction between endogenous and exogenous depression. (shrink)

Despite concerns about the relationships between health professionals and the medical device industry, the issue has received relatively little attention. Prevalence data are lacking; however, qualitative and survey research suggest device industry representatives, who are commonly present in clinical settings, play a key role in these relationships. Representatives, who are technical product specialists and not necessarily medically trained, may attend surgeries on a daily basis and be available to health professionals 24 hours a day, 7 days a week, to provide (...) advice. However, device representatives have a dual role: functioning as commissioned sales representatives at the same time as providing advice on approaches to treatment. This duality raises the concern that clinical decision-making may be unduly influenced by commercial imperatives. In this paper, we identify three key ethical concerns raised by the relationship between device representatives and health professionals: impacts on healthcare costs, the outsourcing of expertise and issues of accountability and informed consent. These ethical concerns can be addressed in part through clarifying the boundary between the support and sales aspects of the roles of device representatives and developing clear guidelines for device representatives providing support in clinical spaces. We suggest several policy options including hospital provision of expert support, formalising clinician conduct to eschew receipt of meals and payments from industry and establishing device registries.
