It is shown, assuming the linear case of Schinzel's Hypothesis, that the first-order theory of the structure $\langle \omega; +, P\rangle$ , where P is the set of primes, is undecidable and, in fact, that multiplication of natural numbers is first-order definable in this structure. In the other direction, it is shown, from the same hypothesis, that the monadic second-order theory of $\langle\omega; S, P\rangle$ is decidable, where S is the successor function. The latter result is proved using a general (...) result of A. L. Semenov on decidability of monadic theories, and a proof of Semenov's result is presented. (shrink)

The thesis of this paper is that games and sports that harm nonhuman animals are unethical because they exceed the permissible limits of optional harm and the more harm the game imposes on the nonhuman animal(s) it objectifies the worse the ethical transgression. Factors in the analysis include the nature of games and sports, the ontology of beings (i.e., human and nonhuman animals) in games, the mitigating power of informed consent among human game-players and its absence among nonhuman game players, (...) harm, and intent.

Even though integrity is widely considered to be an essential aspect of research, there is an ongoing debate on what actually constitutes research integrity. The understanding of integrity ranges from the minimal, only considering falsification, fabrication and plagiarism, to the maximum, blending into science ethics. Underneath these obvious contrasts, there are more subtle differences that are not as immediately evident. The debate about integrity is usually presented as a single, universal discussion, with shared concerns for researchers, policymakers and ‘the public’. (...) In this article, we show that it is not. There are substantial differences between the language of research integrity in the scientific arena and in the public domain. Notably, scientists and policymakers adopt different approaches to research integrity. Scientists tend to present integrity as a virtue that must be kindled, while policy documents and newspapers stress norm enforcement. Rather than performing a conceptual analysis through philosophical reasoning and discussion, we aimed to clarify the discourse of ‘scientific integrity’ by studying its usage in written documents. To this end, large numbers of scientific publications, policy documents and newspaper articles were analysed by means of scientometric and content analysis techniques. The texts were analysed on their usage of the term ‘integrity’ and of frequently co-occurring terms and concepts. A comparison was made between the usage in the various media, as well as between different periods in which they were published through co-word analysis, mapping co-occurrence networks of significant terms and themes.

In these notes it will be argued that our text of Cicero's Philippics may be improved in nearly a score passages by printing manuscript readings that editors have repeatedly spurned. If my detailed arguments are accepted, this article will have also a wider import, serving as a reminder that when a manuscript tradition is bifid both branches should be taken seriously, even if one branch is in general more corrupt than the other, and showing how modern technology may be harnassed (...) as a powerful aid in the study of Cicero's idiom.

ABSTRACTAdopting a temporally distant perspective on stressors reduces distress in adults. Here we investigate whether the extent to which individuals project themselves into the future influences distancing efficacy. We also examined modulating effects of age across adolescence and reactive aggression: factors associated with reduced future-thinking and poor emotion regulation. Participants read scenarios and rated negative affect when adopting a distant-future perspective, near-future perspective, or when reacting naturally. Self-report data revealed significant downregulation of negative affect during the distant-future condition, with a (...) similar though non-significant skin conductance pattern. Importantly, participants who projected further ahead showed the greatest distress reductions. While temporal distancing efficacy did not vary with age, participants reporting greater reactive aggression showed reduced distancing efficacy, and projected themselves less far into the future.

My objective in this project is to explore the concept of moral luck as it relates to sports. I am especially interested in constitutive luck. As a foundation I draw from both Bernard Williams and Thomas Nagel’s classic handling of moral luck, generally. Within the philosophy of sport are similar explorations of this nexus by Robert Simon and David Carr that also factor into the present work. My intent is to put a new lens in front of a puzzle drawn (...) from Torbjörn Tännsjö’s well-known article ‘Is Our Admiration of Sports Heroes Facistoid?’ Specifically, the idea that we might admire an athlete who excels without having worked hard for it. If we may call this puzzle ‘the talent problem,’ the questions driving the present work are as follows: what is the relationship between moral luck and the talent problem, and can this relationship provide a prescription for morally assessing the talent problem? The thesis that this exploratory work suggests that more complex games (and... (shrink)

Patterns in Twentieth-Century European Thought contains interpretive essays in the history of the century's Marxism, psychoanalysis, quantum physics, logic, language theory, philosophy, art, literature, and theology. A concluding essay argues that the philosophy and social theory - not to mention the physics and theology - constitute a twentieth-century Counter-Enlightenment that has replaced the Cartesian- and Newtonian-based Enlightenment of the eighteenth century.

Friedmann–Robertson–Walker (FRW) space–time with bulk viscosity in the context of f(R) gravity is considered. The field equations are solved for the Power and Exponential volumetric expansion. Two types of functional relationship i.e. f(R) = R + bRm and f(R)=R-λ4R\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ \,f(R) = R - \frac{{\lambda^{4} }}{R} $$\end{document} are investigated. The Phantom, Chaplygin gas and Tachyon fields are discussed. It is observed that the universe is open and inflationary.

Herein I engage with the very difficult question of whether the duty to aid (sometimes called a duty of assistance or a duty of beneficence) extends so far as to justify harming persons, perhaps even lethally, in order to protect wild animals. I argue that this question is not nearly as settled as our intuitions may suggest and that Shelly Kagan’s arguments on Defending Animals, contained in his book How to Count Animals, More or Less, provide a rich substrate in (...) which to cultivate ideas on this subject (2019, pp. 248–279). My intuition is that killing a person, even one ‘guilty’ of trying to kill an animal for sport or leisure, is far beyond what a duty to aid can command, though admittedly I find my own intuition somewhat morally dumbfounding. I argue further that Tom Regan’s ‘worse-off principle’ may ease the ever-uncomfortable sense of moral dumbfounding by providing a surer foundation for the intuitive sense that we cannot ethically go so far as to threaten a person with lethal force in defense of nonhuman animals.

Students of the play have not appreciated the merits of W. Dindorf's proposal to delete lines 895–7: his conjecture is not reported by most editors; when reported it is not accepted; and it has been taken seriously perhaps only in an iobiter dictum of Wecklein. Nevertheless, the arguments in its favour are even more powerful than Dindorf realised.
