An analysis of the extension of the Hawking-Penrose singularity theorem to Riemann-Cartan U4 space-times with torsion and spin density is undertaken. The minimal coupling principle in U4 is used to formulate a new expression for the convergence condition autoparallels in Einstein-Cartan theory. The Gödel model with torsion is given as an example.

Integrating power dependence and gender role theories, we investigate the interactive effects of followers’ gender and leaders’ Machiavellian orientation in predicting followers’ usage of upward influence tactics. Using a sample of 156 matched leader–follower dyads, we found that followers’ gender moderated the relationship between Time 1 leaders’ Machiavellian orientation and followers’ use of upward influence tactics at Time 2. Specifically, the relationship between Time 1 leaders’ Machiavellianism and Time 2 followers’ ingratiation was significant and positive for women followers and non-significant (...) for men followers, while the relationship between Time 1 leaders’ Machiavellianism and Time 2 followers’ assertiveness was significant and positive for men followers but non-significant for women followers. These results suggest that gender plays an important role in how followers react to Machiavellian leaders. The social and ethical implications of these findings are discussed. (shrink)

Code-based cryptography is currently the second most promising post-quantum mathematical tool for quantum-resistant algorithms. Since in 2022 the first post-quantum standard Key Encapsulation Mechanism, Kyber (a latticed-based algorithm), was selected to be established as standard, and after that the National Institute of Standards and Technology post-quantum standardization call focused in code-based cryptosystems. Three of the four candidates that remain in the fourth round are code-based algorithms. In fact, the only non-code-based algorithm (SIKE) is now considered vulnerable. Due to this landscape, (...) it is crucial to update previous results about these algorithms and their functioning. The Fujisaki-Okamoto transformation is a key part of the study of post-quantum algorithms and in this work we focus our analysis on Classic McEliece, BIKE and HQC proposals, and how they apply this transformation to obtain IND-CCA semantic security. Since after security the most important parameter in the evaluation of the algorithms is performance, we have compared the performance of the code-based algorithms of the NIST call considering the same architecture for all of them.

The paper defends the thesis that for S to V intentionally is for S to V as (in the way) S intended to. For the normal agent the relevant sort of intention is an intention that one's intention to V generate an instance of one's V-ing along some (usually dimly-conceived) productive path. Such an account allows us to say some actions are intentional to a greater or lesser extent (a desirable option for certain cases of wayward causal chains), preserves the (...) intuitive link between intention and intentionally, and supports the common sense view that the concept of intending is more basic than those of acting with an intention and of acting intentionally. The remainder of the paper responds to certain apparent counter-examples offered by Audi, Harman, and Bratman. In the course of this, I discuss connections between intending to V and hoping to V, and I argue that one can intend to do what one doesn't expect to do, and that one always intends what one attempts.

This article responds to logical and social theses proposed by Professor José Medina in discussing the relativity of identity. In exploring the metaphor of family resemblance, the author argues that its causal mechanism is biological, not social; particular features of being a woman, or of belonging to a racial or ethnic group, cannot be reduced to social constructions. The article skeptically discusses the supposed importance of sex, race, and ethnicity to a person’s individual identity, and suggests that moral significance finds (...) its origin and grounding elsewhere. It concludes that no liberation can be ‘complete, or even adequate’ until it liberates the mind from ‘“scripts” rooted in the delusion of “collective identities”’. (shrink)

This essay rebuts Gary Seay's efforts to show that committing euthanasia need not conflict with a physician's professional duties. First, I try to show how his misunderstanding of the correlativity of rights and duties and his discussion of the foundation of moral rights undermine his case. Second, I show aspects of physicians' professional duties that clash with euthanasia, and that attempts to avoid this clash lead to absurdities. For professional duties are best understood as deriving from professional virtues and the (...) commitments and purposes with which the professional as such ought to act, and there is no plausible way in which her death can be seen as advancing the patient's medical welfare. Third, I argue against Prof. Seay's assumption that apparent conflicts among professional duties must be resolved through "balancing" and argue that, while the physician's duty to extend life is continuous with her duty to protect health, any duty to relieve pain is subordinate to these. Finally, I show that what is morally determinative here, as throughout the moral life, is the agent's intention and that Prof. Seay's implicitly preferred consequentialism threatens not only to distort moral thinking but would altogether undermine the medical (and any other) profession and its internal ethics.

This paper critically examines a formal argument against deducing ‘ought’-judgments from ‘is’-judgments, an argument suggested by a literal reading of a famous passage in Hume'sTreatise of Human Nature. According to this argument, judgments of the two kinds have different logical structures (i.e., their subjects are differently related to their predicates) and this difference disallows cross-categorical deductive inferences. I draw on Fregean accounts of the ‘is’- copula and on syntactical interpretations of ‘ought’-judgments that have become standard in deontic logic to argue (...) that twentieth century work in philosophical grammar and logic casts doubt on all three of the argument's premises.

I first sketch an account of humility as a character trait in which we are unimpressed with our good, envied, or admired features, achievements, etc., where these lack significant salience for our image of ourselves, because of the greater prominence of our limitations and flaws. I situate this view among several other recent conceptions of humility (also called modesty), dividing them between the inward-directed and outward-directed, distinguish mine from them, pose problems for each alternative account, and show how my understanding (...) of humility captures truths present but exaggerated in several of them. Responding to some problems for my view, including what I call “Driver’s Paradox”(i.e., the strangeness of someone’s proclaiming ‘I’m humble!’), I suggest that some over-ambitious claims about our moral responsibilities may indicate a lack of proper humility. I discuss the relationship of the character trait of humility both to what humiliates and to what humbles, concluding with consideration of the background assumptions against which, and the circumstances in which, humility may reasonably be classified as a moral virtue.

A genuine bioethics would be fiercely devoted to human life (bios) and would express that devotion by articulating as well as advocating moral virtues that rigorously protect that value against the temptation to see life in purely instrumental terms. In my view, no genuine bioethics exists today. In what follows, I will question two fundamental assumptions often presumed in discussions of euthanasia and assisted suicide. These are (i) the agent does will her victim (i.e., her putative beneficiary) some significant human (...) good, e.g., relief from pain, escape from becoming a burden to loved ones, a dignified death, or simply self-determination; (ii) in purposely helping someone to kill herself or in killing her for her own good, the agent wills her no serious harm. Put differently, I question the assumption of ‘mercy’ in so-called ‘mercy-killing’. (shrink)

Drawing chiefly on recent sources, in Part One I sketch an untraditional way of articulating what I claim to be central elements of traditional Catholic morality, treating it as based in virtues, focused on the recipients (“patients”) of our attention and concern, and centered in certain person-to-person role-relationships. I show the limited and derivative places of “natural law,” and therefore of sin, within that framework. I also sketch out some possible implications for medical ethics of this approach to moral theory, (...) and briefly contrast these with the influential alternative offered by the “principlism” of Beauchamp and Childress. In Part Two, I turn to a Catholic understanding of the nature and meaning of human suffering, drawing especially on writings and addresses of the late Pope John Paul II. He reminds us that physical and mental suffering can provide an opportunity to share in Christ's salvific sacrifice, better to see the nature of our earthly vocation, and to reflect on the dependence that inheres in human existence. At various places, and especially in my conclusion, I suggest a few ways in which this can inform bioethical reflection on morally appropriate responses to those afflicted by physical or mental pain, disability, mental impairment, disease, illness, and poor health prospects. My general point is that mercy must be informed by appreciation of the person's dignity and status. Throughout, my approach is philosophical rather than theological. (shrink)

Morality and religion: intimately wed, violently opposed, or something else? Discussion of this issue appears in pop culture, the academy, and the media―often generating radically opposed views. At one end of the spectrum are those who think that unless God exists, ethics is unfounded and the moral life is unmotivated. At the other end are those who think that religious belief is unnecessary for―and even a threat to―ethical knowledge and the moral life. -/- This volume provides an accessible, charitable discussion (...) that represents a range of views along this spectrum. The book begins with a lively debate between Paul Kurtz and William Lane Craig on the question, Is goodness without God good enough? Kurtz defends the affirmative position and Craig the negative. Following the debate are new essays by prominent scholars. These essays comment on the debate and advance the broader discussion of religion and morality. The book closes with final responses from Kurtz and Craig. (shrink)

The essay contrasts the thesis that deserved punishment is punishment which, as deserved, is obligatory with the weaker thesis that it is punishment which, as deserved, is permissible. The author first outlines an account of the meaning of desert-claims which entails only the weaker thesis and then defends this account against criticisms levied in a recent article that it is ambiguous, cannot explain the moral significance of desert, justifies letting people profit from their crimes, and permits unequal treatment. The essay (...) proceeds to a critique of George Sher's view of deserved punishment, faulting Sher for: (1) his reliance on an implausible understanding of benefits, (2) his inability to justify the punishment of crime-victims for their own crimes, and (3) the inadequacy of his defense of mercy. Finally, the author sketches a role-centered conception of morality within which it becomes clearer how deserved punishment can be justified as the victim's ties to the criminal, and the role-responsibilities derivative therefrom, are vitiated by the latter's misdeeds.

Contrasting loving our neighbors with utilitarians’ demand to maximize good reveals important metatheoretic structures and dynamics that I call virtues- basing, input drive, role centering, and patient focus. First, love (good will) is a virtue; such virtues are foundational to both moral obligations and the impersonally valuable. Second, part of loving is acting lovingly. Whether and how I act lovingly, and how loving it is, is a matter of motivation; this input-driven account contrasts with highlighting actions’ outcome. Third, in regarding (...) someone as our neighbor we view her in relation to ourselves; a role-centered perspective shows that a wide range of person-to-person role-relationships constitute moral life. Fourth, if our moral task is loving each person, the moral question is how we respond to each person’s relevant welfare and needs, focusing on those toward someone acts (moral patients), not on maximizing good across persons or producing an optimal world.
