Advocates of Mars colonies commonly assert a supposed obligation to act so as to maximize the longevity of the human species. When this principle is defended, it is often by appeal to the alleged costs—of incoherence or misanthropy—of denying it. Against this supposed obligation, I argue for two theses. The modest thesis: it is not incoherent and need not be misanthropic to prefer human extinction sooner rather than later. The ambitious thesis: we should prefer human extinction sooner rather than later. (...) The supposed obligation to prolong our species is no justification of human activities in space. (shrink)

This article defends the use of fanciful examples within the method of wide reflective equilibrium. First, it characterizes the general persuasive role of described cases within that method. Second, it suggests three criteria any example must meet in order to succeed in this persuasive role; fancifulness has little or nothing to do with whether an example is able to meet these criteria. Third, it discusses several general objections to fanciful examples and concludes that they are objections to the abuse of (...) described cases; they identify no special problem with fanciful examples.

Does disability make a person worse off? I argue that the best answer is yes AND no, because we can be worse off in two conceptually distinct ways. Disabilities usually make us worse off in one way (typified by facing hassles) but not in the other (typified by facing loneliness). Acknowledging two conceptually distinct ways to be worse off has fundamental implications for philosophical theories of well-being.

AI systems have often been found to contain gender biases. As a result of these gender biases, AI routinely fails to adequately recognize the needs, rights, and accomplishments of women. In this article, we use Axel Honneth’s theory of recognition to argue that AI’s gender biases are not only an ethical problem because they can lead to discrimination, but also because they resemble forms of misrecognition that can hurt women’s self-development and self-worth. Furthermore, we argue that Honneth’s theory of recognition (...) offers a fruitful framework for improving our understanding of the psychological and normative implications of gender bias in modern technologies. Moreover, our Honnethian analysis of gender bias in AI shows that the goal of responsible AI requires us to address these issues not only through technical interventions, but also through a change in how we grant and deny recognition to each other.

This article offers two arguments for the conclusion that we should refuse on moral grounds to establish a human presence on the surface of Mars. The first argument appeals to a principle constraining the use of invasive or destructive techniques of scientific investigation. The second appeals to a principle governing appropriate human behavior in wilderness. These arguments are prefaced by two preliminary sections. The first preliminary section argues that authors working in space ethics have good reason to shift their focus (...) away from theory-based arguments in favor of arguments that develop in terms of pretheoretic beliefs. The second argues that of the popular justifications for sending humans to Mars only appeals to scientific curiosity can survive reflective scrutiny. (shrink)

A dealbreaker, in the sense developed in this essay, is a relationship between a person's psychology and an aspect of an artwork to which they are exposed. When a person has a dealbreaking aversion to an aspect of a work, they are blocked from embracing the work's aesthetically positive features. I characterize dealbreakers, distinguish this response from other negative responses to an artwork, and argue that the presence or absence of a dealbreaker is in some cases an appropriate target of (...) moral evaluation. I then use the concept of dealbreakers to develop a new approach to the question of our moral obligations with respect to the work of immoral artists, arguing that there is no general obligation binding us to cultivate or eliminate a dealbreaking aversion to their work. I conclude by suggesting several other philosophical debates that could benefit from a focus on dealbreakers. (shrink)

In her short story “Stable Strategies for Middle Management,” Eileen Gunn imagines a future in which Margaret, an office worker, seeks radical genetic enhancements intended to help her secure the middle-management job she wants. One source of the story’s tension and dark humor is dramatic irony: readers can see that the enhancements Margaret buys stand little chance of making her life go better for her; enhancing is, for Margaret, probably a prudential mistake. This paper argues that our positions in the (...) real world are sufficiently similar to Margaret’s position in Gunn’s fictional world that we should take this story seriously as grounding an argument from analogy for the conclusion that radical genetic enhancements are, for us, probably a prudential mistake. The paper then defends this method. When the question at hand is one of speculative ethics, there is no method better fit to the purpose than argument from analogy to speculative fiction. (shrink)

Voorstanders van levensverlenging vooronderstellen dat langer leven wenselijk is en dat ouderdom en de dood dat niet zijn. Maar is een leven zonder dood eigenlijk wel nastrevenswaardig? In dit essay beargumenteer ik dat de dood een essentieel onderdeel van een zinvol leven is. Het is daarom niet eindigheid, maar eeuwigheid die als een bedreiging voor het leven zou moeten worden gezien.

Many people suspect it is morally wrong to watch the graphically violent horror films colloquially known as gorefests. A prominent argument vindicating this suspicion is the Argument from Reactive Attitudes (ARA). The ARA holds that we have a duty to maintain a well-functioning moral psychology, and watching gorefests violates that duty by threatening damage to our appropriate reactive attitudes. But I argue that the ARA is probably unsound. Depictions of suffering and death in other genres typically do no damage to (...) our appropriate reactive attitudes, and until we locate a relevant difference between these depictions in gorefests and in other genres, we should assume that the depictions in gorefests do no damage. I consider and reject three candidate differences: in artistic merit, meaningfulness, and audience orientation. Until genre skeptics identify a relevant difference, we should accept the taste for gory fictions as we would any other morally innocuous variation in taste. (shrink)

If we had the ability to terraform Mars, would it be morally permissible to do it? This article surveys three preservationist arguments for the conclusion that we should not terraform Mars and three interventionist arguments that we should. The preservationist arguments appeal to a duty to conserve objects of special scientific value, a duty to preserve special wilderness areas, and a duty not to display vices characteristic of past colonial endeavors on Earth. The interventionist arguments appeal to a duty to (...) fulfill our pioneering nature, a duty to extend the lifespan of our species, and a duty to restore the ecosystems Mars may once have housed. The preservationist arguments are stronger than the interventionist arguments; terraforming Mars is probably morally wrong. (shrink)

Most work in neo-Aristotelian virtue ethics begins by supposing that the virtues are the traits of character that make us good people. Secondary questions, then, include whether, why, and in what ways the virtues are good for the people who have them. This essay is an argument that the neo-Aristotelian approach is upside down. If, instead, we begin by asking what collection of character traits are good for us---that is, what collection of traits are most likely to promote our own (...) well-being---we find a collection of traits a lot like the traditional slate of virtues. This suggests an egoistic theory of the virtues: the virtues just are those traits of character that reliably promote the well-being of their possessor. In addition to making the positive case for character egoism, I defend it from anticipated objections. I argue that character egoism doesn't inherit the problems of ethical egoism, and conclude by offering character-egoist accounts of two virtues traditionally thought to be fundamentally other-regarding: honesty and justice.

Some logic students falter at the transition from the mechanical method of truth tables to the less-mechanical method of natural deduction. This short paper introduces a word game intended to ease that transition.

The primary purpose of the study was to determine the significant difference in the student performance in English selected topics through self-learning modules based on their sections. The respondents of the study are the 123 fourth-grade students of a central elementary school. Utilizing the descriptive-comparative type of research with Mean and Analysis of Variance as statistical tools, it was found that the level of student performance was satisfactory and there is no significant difference in the level of student's performance when (...) grouped according to section. The researchers, therefore, recommended that the school may implement face-to-face instruction with the help of the parents to address the needs of the students for their academic performance. Teachers should conduct a remedial class for the students with low academic performance and include assessments to assist and help the students develop their cognitive skills. Furthermore, future researchers were recommended to conduct similar studies with wider scope, with different research design and set of respondents. (shrink)

Making Sense of Messages Making Sense of Messages, now in its second edition, retains the apprenticeship approach which facilitates effectively learning the complex content and skills of rhetorical theory and criticism. A new chapter on “The Rhetoric of Ignorance” provides needed theory and examples that help students deal with the new rhetorical landscape marked by such discursive complexities as “fake news,” “whataboutism,” and denial of science that creates rather than reduces uncertainty in public argument. A new chapter, “Curating and Analyzing (...) Multimodal Mediated Rhetoric,” deals with problems of media criticism in the digital age. It provides theory, models of application, and commentary that help novice critics understand and rnindfully practice criticism that leads to insight, not mere opinion. Throughout the book, extended and updated examples and commentaries are designed to promote “novice—to—expert” agency in students. This textbook is ideal for introductory courses in contemporary rhetoric, rhetorical criticism, and critical analysis of mass media. Mark Stoner is Professor Emeritus of Communication Studies University, Sacramento. at California State. (shrink)

Doing Practical Ethics supports the deliberate practice of philosophical skills relevant to understanding, evaluating, and developing arguments in forms commonly used in the field of practical ethics. Each chapter includes an explanation of a specific moral reasoning skill, demonstration exercises with sample solutions that offer students immediate feedback on their initial practice attempts, and extensive sets of practice exercises. It is suitable for any ethics course that centrally features argument from principle, argument from analogy, or inference to the best explanation. (...) It may be used as a standalone text in a debate-focused course. Paired with an anthology in a readings-focused course, it will help students develop the skills they need to understand and evaluate the arguments in the assigned readings. (shrink)

Ian Stoner has recently argued that we ought not to colonize Mars because doing so would flout our pro tanto obligation not to violate the principle of scientific conservation, and there is no countervailing considerations that render our violation of the principle permissible. While I remain agnostic on, my primary goal in this article is to challenge : there are countervailing considerations that render our violation of the principle permissible. As such, Stoner has failed to establish that we (...) ought not to colonize Mars. I close with some thoughts on what it would take to show that we do have an obligation to colonize Mars and related issues concerning the relationship between the way we discount our preferences over time and projects with long time horizons, like space colonization.

Over the course of the Twilight series, Bella strives to and eventually succeeds in convincing Edward to turn her into a vampire. Her stated reason for this is that it will allow her to be with Edward forever. In this essay, I consider whether this type of immortality is something that would be good for Bella, or indeed for any of us. I begin by suggesting that Bella's own viewpoint is consonant with that of Leo Tolstoy, who contends that one (...) could not have meaningful life without immortality, because only immortality could allow one to make a permanent difference in the world. I argue that this characterization of a meaningful life is problematic, however, insofar as (1) immortality is neither sufficient nor necessary for having such an impact and (2) there is little reason to think that having such an impact is constitutive of a meaningful life. I go on to consider Edward's fear that vampires lack a soul as it relates to Martha Nussbaum's claim that immortal beings would be less capable of certain paradigmatic human values and virtues such as courage, love, or self-sacrifice. I suggest, contra Nussbaum, that Carlisle provides an example of an immortal who displays recognizably human virtues. However, the possibility of Carlisle's being virtuous in this way depends on the existence of other creatures who are mortal. -/- I close by considering the problem of boredom, as articulated by Bernard Williams. According to Williams, a meaningful human life is constituted by certain categorical desires such as the desire to raise children or to create art. The projects aimed at accomplishing these desires are necessarily finite in length, and cannot be repeated indefinitely without losing their value. I argue that many, though perhaps not all, of the immortals described in the series suffer from such boredom. For example, Edward and Rosalie struggle to find meaning in their lives and most werewolves choose to age and die normally after a certain time. Perhaps more significantly, many of the non-"vegetarian" vampires seem to have become entirely divorced from any recognizably human projects or values, and have become focused entirely on satisfying their immediate desires. These examples provide some reason to think that many of Bella's reasons for living, which are essentially tied to her mortality, are not likely to be met by becoming immortal. While this does not show that her choice to become a vampire will leave her ultimately unhappy, it does suggest that her doing so represents a considerable sacrifice. (shrink)
