We propose that the prevalent moral aversion to AWS is supported by a pair of compelling objections. First, we argue that even a sophisticated robot is not the kind of thing that is capable of replicating human moral judgment. This conclusion follows if human moral judgment is not codifiable, i.e., it cannot be captured by a list of rules. Moral judgment requires either the ability to engage in wide reflective equilibrium, the ability to perceive certain facts as moral considerations, moral (...) imagination, or the ability to have moral experiences with a particular phenomenological character. Robots cannot in principle possess these abilities, so robots cannot in principle replicate human moral judgment. If robots cannot in principle replicate human moral judgment then it is morally problematic to deploy AWS with that aim in mind. Second, we then argue that even if it is possible for a sufficiently sophisticated robot to make ‘moral decisions’ that are extensionally indistinguishable from (or better than) human moral decisions, these ‘decisions’ could not be made for the right reasons. This means that the ‘moral decisions’ made by AWS are bound to be morally deficient in at least one respect even if they are extensionally indistinguishable from human ones. Our objections to AWS support the prevalent aversion to the employment of AWS in war. They also enjoy several significant advantages over the most common objections to AWS in the literature.

ABSTRACTThe jus ad bellum criterion of right intention is a central guiding principle of just war theory. It asserts that a country’s resort to war is just only if that country resorts to war for the right reasons. However, there is significant confusion, and little consensus, about how to specify the CRI. We seek to clear up this confusion by evaluating several distinct ways of understanding the criterion. On one understanding, a state’s resort to war is just only if it (...) plans to adhere to the principles of just war while achieving its just cause. We argue that the first understanding makes the CRI superfluous, because it can be subsumed under the probability of success criterion. On a second understanding, a resort to war is just only if a state’s motives, which explain its resort to war, are of the right kind. We argue that this second understanding of the CRI makes it a significant further obstacle to justifying war. However, this second understanding faces a possible infinite regress problem, wh...

To many, the idea of autonomous weapons systems (AWS) killing human beings is grotesque. Yet critics have had difficulty explaining why it should make a significant moral difference if a human combatant is killed by an AWS as opposed to being killed by a human combatant. The purpose of this paper is to explore the roots of various deontological concerns with AWS and to consider whether these concerns are distinct from any concerns that also apply to long-distance, human-guided weaponry. We (...) suggest that at least one major driver of the intuitive moral aversion to lethal AWS is that their use disrespects their human targets by violating the martial contract between human combatants. On our understanding of this doctrine, service personnel cede a right not to be directly targeted with lethal violence to other human agents alone. Artificial agents, of which AWS are one example, cannot understand the value of human life. A human combatant cannot transfer his privileges of targeting enemy combatants to a robot. Therefore, the human duty-holder who deploys AWS breaches the martial contract between human combatants and disrespects the targeted combatants. We consider whether this novel deontological objection to AWS forms the foundation of several other popular yet imperfect deontological objections to AWS. (shrink)

In July 2020, more than 1,000 companies that advertise on social media platforms withdrew their business, citing failures of the platforms (especially Facebook) to address the proliferation of harmful content. The #StopHateForProfit movement invites reflection on an understudied topic: the ethics of boycotting by corporations. Under what conditions is corporate boycotting permissible, required, supererogatory, or forbidden? Although value-driven consumerism has generated significant recent discussion in applied ethics, that discussion has focused almost exclusively on the consumption choices of individuals. As this (...) article underscores, value-driven consumerism by business corporations complicates these issues and invites further examination. We propose principles for the ethics of boycotting by corporations, indicate how these principles relate to different CSR paradigms, and show how these insights can help assess recent instances of corporate boycotting.

Robert Sparrow argues that several initially plausible arguments in favor of the deployment of autonomous weapons systems (AWS) in warfare fail, and that their deployment faces a serious moral objection: deploying AWS fails to express the respect for the casualties of war that morality requires. We critically discuss Sparrow’s argument from respect and respond on behalf of some objections he considers. Sparrow’s argument against AWS relies on the claim that they are distinct from accepted weapons of war in that they (...) either fail to transmit an attitude of respect or they transmit an attitude of disrespect. We argue that this distinction between AWS and widely accepted weapons is illusory, and so cannot ground a moral difference between AWS and existing methods of waging war. We also suggest that, if deploying conventional soldiers in some situation would be permissible, and if we could expect deploying AWS to cause fewer civilian casualties, then it would be consistent with an intuitive understanding of respect to deploy AWS in this situation.

In this paper, we outline a new method for evaluating the human impact of machine-learning applications. In partnership with Underwriters Laboratories Inc., we have developed a framework to evaluate the impacts of a particular use of machine learning that is based on the goals and values of the domain in which that application is deployed. By examining the use of artificial intelligence in particular domains, such as journalism, criminal justice, or law, we can develop more nuanced and practically relevant understandings (...) of key ethical guidelines for artificial intelligence. By decoupling the extraction of the facts of the matter from the evaluation of the impact of the resulting systems, we create a framework for the process of assessing impact that has two distinctly different phases.

We investigate the question of whether (and if so why) creating or distributing deepfake pornography of someone without their consent is inherently objectionable. We argue that nonconsensually distributing deepfake pornography of a living person on the internet is inherently pro tanto wrong in virtue of the fact that nonconsensually distributing intentionally non-veridical representations about someone violates their right that their social identity not be tampered with, a right which is grounded in their interest in being able to exercise autonomy over (...) their social relations with others. We go on to suggest that nonconsensual deepfakes are especially worrisome in connection with this right because they have a high degree of phenomenal immediacy, a property which corresponds inversely to the ease with which a representation can be doubted. We then suggest that nonconsensually creating and privately consuming deepfake pornography is worrisome but may not be inherently pro tanto wrong. Finally, we discuss the special issue of whether nonconsensually distributing deepfake pornography of a deceased person is inherently objectionable. We argue that the answer depends on how long it has been since the person died. (shrink)

Many social trends are conspiring to drive the adoption of greater automation in society, and we will certainly see a greater offloading of human decisionmaking to robots in the future. Many of these decisions are morally salient, including decisions about how benefits and burdens are distributed. Roboticists and ethicists have begun to think carefully about the moral decision making apparatus for machines. Their concerns often center around the plausible claim that robots will lack many of the mental capacities that are (...) indispensable in human moral decision making, such as empathy. To the extent that robots may be robustly artificially intelligent, these concerns subside, but they give way to new worries about creating artificial agents to do our bidding, if those artificial agents have moral standing. We suggest that the question of AI consciousness poses a dilemma. Whether artificially intelligent agents will be conscious or not, we will face serious difficulties in programming them to reliably make moral decisions. (shrink)

Cyberweapons are software and software, at least intuitively, is nonphysical. Several authors have noted that this potentially renders problematic the application of normative frameworks like UN Charter Article 2(4) to cyberweapons. If Article 2(4) only proscribes the use of physical force, and if cyberweapons are nonphysical, then cyberweapons fall outside the purview of Article 2(4). This article explores the physicality of software, examining Stuxnet in particular. First, I show that with a few relatively uncontroversial metaphysical claims we can secure the (...) conclusion that Stuxnet is physical. In particular, there exist instances of Stuxnet that are both located in space and causally efficacious, and this is very strong evidence for their being physical. Second, I argue that the question of physicality is actually irrelevant for the moral evaluation of an attack like Stuxnet because of its undeniably physical effects. Finally, I argue that some features of Stuxnet should make us optimistic about the prospects for discrimination and proportionality in cyberwarfare. (shrink)

"A runaway trolley is speeding down a track" So begins what is perhaps the most fecund thought experiment of the past several decades since its invention by Philippa Foot. Since then, moral philosophers have applied the "trolley problem" as a thought experiment to study many different ethical conflicts - and chief among them is the programming of autonomous vehicles. Nowadays, however, very few philosophers accept that the trolley problem is a perfect analogy for driverless cars or that the situations autonomous (...) vehicles face will resemble the forced choice of the unlucky bystander in the original thought experiment. This book represents a substantial and purposeful effort to move the academic discussion beyond the trolley problem to the broader ethical, legal, and social implications that autonomous vehicles present. There are still urgent questions waiting to be addressed, for example: how AVs might interact with human drivers in mixed or "hybrid" traffic environments; how AVs might reshape our urban landscapes; what unique security or privacy concerns are raised by AVs as connected devices in the "Internet of Things"; how the benefits and burdens of this new technology, including mobility, traffic congestion, and pollution, will be distributed throughout society; and more. An attempt to map the landscape of these next-generation questions and to suggest preliminary answers, this volume draws on the disciplines of philosophy, sociology, economics, urban planning and transportation engineering, business ethics and more, and represents a global range of perspectives.

Few sectors are more affected by COVID-19 than higher education. There is growing recognition that reopening the densely populated communities of higher education will require surveillance technologies, but many of these technologies pose threats to the privacy of the very students, faculty, and staff they are meant to protect. The authors have a history of working with our institution’s governing bodies to provide ethical guidance on the use of technologies, especially including those with significant implications for privacy. Here, we draw (...) on that experience to provide guidelines for using surveillance technologies to reopen college campuses safely and responsibly, even under the specter of covid. We aim to generalize our recommendations, so they are sensitive to the practical realities and constraints that universities face. (shrink)

Rule consequentialism is usually taken to recommend a single ideal code for all moral agents. Here I argue that, depending on their theoretical mo- tivations, some rule consequentialists have good reasons to be relativists. Rule consequentialists who are moved by consequentialist considerations ought to support a scheme of multiple relativized moral codes because we could expect such a scheme to have better consequences in terms of impartial aggregate well- being than a single universal code. Rule consequentialists who nd compelling the (...) theory’s coherence with our considered moral intuitions should do the same because a scheme of multiple codes could better cohere with our intuitions about costless bene ts, though these intuitions must be weighed against our allegiance to moral universalism.

Desert is a notion ubiquitous in our moral discourse, and the importance of its dictates is perhaps clearest when dealing with the distribution of material resources. George Sher has provided one account of desert in wages, answering the question, “How do workers deserve their wage?” Sher relies on the violation of preexisting “independent standards” that dictate how much of a certain good we think people are entitled to in general. When these standards are violated, they call for an offsetting response (...) at a later point in time in order to restore the moral equilibrium. I argue that this formalization of desert is flawed at the theoretical level and that it has further difficulties when applied to wages in particular. Lastly, I offer some brief remarks about what I think are the criteria for establishing desert in wages. (shrink)

From his earliest work on personal identity to his last on the value of truthfulness, the ideas and arguments of Bernard Williams - in the metaphysics of personhood, in the history of philosophy, but especially in ethics and moral psychology - have proved sometimes controversial, often influential, and always worth studying. This book provides a comprehensive account of Williams's many significant contributions to contemporary philosophy. Topics include personal identity, various critiques of moral theory, practical reasoning and moral motivation, truth and (...) objectivity, and the relevance of ancient Greece to modern life. It not only positions Williams among these important philosophical topics, but also with regard to the views of other philosophers, including prominent forerunners such as Hume and Nietzsche and contemporary thinkers such as, Nagel, McDowell, MacIntyre and Taylor. The fragmentary nature of Williams's work is addressed and recurring themes and connections within his work are brought to light. (shrink)

When are morally good actions beautiful, when indeed they are? In this paper, it is argued that morally good actions are beautiful when they appear to express the deep or true self, and in turn tend to give rise to an emotion which is characterised by feelings of being moved, unity, inspiration, and meaningfulness, inter alia. In advancing the case for this claim, it is revealed that there are additional sources of well-formedness in play in the context of moral beauty (...) in addition to those that have tended to be focused on to date: one which is connected to imagining a deep location for the goodness concerned, and another which is connected to imagining that the goodness stems from capacities which are essential to the person.

What is the nature of the concept BEAUTY? Does it differ fundamentally from nearby concepts such as PRETTINESS? It is argued that BEAUTY, but not PRETTINESS, is a dual-character concept. Across a number of contexts, it is proposed that BEAUTY has a descriptive sense that is characterised by, inter alia, having intrinsically pleasing appearances; and a normative sense associated with deeply-held values. This account is supported across two, pre-registered, studies (N=500), and by drawing on analysis of corpus data. It is (...) suggested that this can help to explain why beauty, unlike prettiness, is thought to be deep in both the sense of being important, and in the sense of being less closely tied to sensory surfaces.

Why are moral actions beautiful, when indeed they are? This paper assesses the view, found most notably in Schiller, that moral actions are beautiful just when they present the appearance of freedom by appearing to be the result of internal harmony (the Schillerian Internal Harmony Thesis). I argue that while this thesis can accommodate some of the beauty involved in contrasts of the ‘continent’ and the ‘fully’ virtuous, it cannot account for all of the beauty in such contrasts, and so (...) needs to be weakened considerably (to the Internal Harmony Thesis). To account for the remaining beauty that cannot be fully accommodated even by this revised thesis, as well as the beauty contained in contrasts that involve agents who experience internal conflict as a result of being sensitive to different sources of moral value to an appropriate extent, a number of further theses need to be posited: namely, that the beauty of some moral actions is to be accommodated in terms of internal disharmony (the Internal Disharmony Thesis), and in terms of a felt harmony between the appreciator of the action and the executor of the action (the Affective Harmony Thesis). As such, in contrast to Schiller, I suggest that we need to take a pluralist and context-sensitive approach to accommodating the beauty of moral actions. (shrink)

What is a language? What do scientific grammars tell us about the structure of individual languages and human language in general? What kind of science is linguistics? These and other questions are the subject of Ryan M. Nefdt's Language, Science, and Structure. -/- Linguistics presents a unique and challenging subject matter for the philosophy of science. As a special science, its formalisation and naturalisation inspired what many consider to be a scientific revolution in the study of mind and language. (...) Yet radical internal theory change, multiple competing frameworks, and issues of modelling and realism have largely gone unaddressed in the field. Nefdt develops a structural realist perspective on the philosophy of linguistics which aims to confront the aforementioned topics in new ways while expanding the outlook toward new scientific connections and novel philosophical insights. On this view, languages are real patterns which emerge from complex biological systems. Nefdt's exploration of this novel view will be especially valuable to those working in formal and computational linguistics, cognitive science, and the philosophies of science, mathematics, and language.

Most accounts of cognitive scaffolding focus on ways that external structure can support or augment an agent’s cognitive capacities. We call cases where the interests of the user are served benign scaffolding and argue for the possibility and reality of hostile scaffolding. This is scaffolding which depends on the same capacities of an agent to make cognitive use of external structure as in benign cases, but that undermines or exploits the user while serving the interests of another agent. We develop (...) criteria for scaffolding being hostile and show by reference to examples including the design features of electronic gambling machines and casino management systems that hostile scaffolding exists and can be highly effective. In cases where the scaffolding is deep and permits the offloading of significant cognitive work, hostile scaffolding exploitatively manipulates cognitive processing itself. Given the extent of human reliance on scaffolding this is an important and neglected vulnerability. [This is an updated version of the paper, added in February 2023.]. (shrink)

Love is most often associated with happiness, satisfaction and pleasure. But it has a darker side we ignore at our peril. Love is often an uncomfortable and difficult feeling. The people we love can let us down badly. And the ways we love are often quite different to the romantic ideals society foists upon us. Since we are inevitably disappointed by love, wouldn't we be better off without it? No, says Carrie Jenkins. Instead, we need a new philosophy of (...) love, one that recognizes that the pain and suffering love causes are a natural, even a good part of what makes love worthwhile. What Jenkins calls "sad love" offers no bogus "happy ever afters." Rather, it tries to find a way properly to integrate heartbreak and disappointment into the lived experience of love"--Page 4 of cover. (shrink)

Perception provides us with access to the external world, but that access is shaped by our own experiential histories. Through perceptual learning, we can enhance our capacities for perceptual discrimination, categorization, and attention to salient properties. We can also encode harmful biases and stereotypes. This article reviews interdisciplinary research on perceptual learning, with an emphasis on the implications for our rational and normative theorizing. Perceptual learning raises the possibility that our inquiries into topics such as epistemic justification, aesthetic criticism, and (...) moral knowledge should include not only an examination of cognition but also of perception.

Does the formation of delusions involve abnormal reasoning? According to the prominent ‘two-factor’ theory of delusions (e.g. Coltheart, 2007), the answer is yes. The second factor in this theory is supposed to affect a deluded individual's ability to evaluate candidates for belief. However, most published accounts of the two-factor theory have not said much about the nature of this second factor. In an effort to remedy this shortcoming, Coltheart, Menzies and Sutton (2010) recently put forward a Bayesian account of inference (...) in delusions. I outline some criticisms of this important account, and sketch an alternative account of delusional inference that, I argue, avoids these criticisms. Specifically, I argue that the second factor in delusion formation involves a systematic deviation from Bayesian updating, a deviation that may be characterized as a bias towards ‘explanatory adequacy’. I present a numerical model of this idea and show that my alternative account is broadly consistent with prominent prediction error models of delusion formation (e.g. Corlett, Murray et al., 2007).

Excerpt from The Passing of Plato The stupendous changes that have been wrought in the material life of the civilized races in a short period of time by the progress of modern science have been generally recognized. We have to make only a casual investigation into the history of the production of the things that would come under our view at our first turn, to find complete revolution in production, manufacture, and distribution. We find further that it is not in (...) each a single change, but revolution on revolution the most radical. For example, in less than twenty-five years the immense and complicated business of transit in our cities has passed from omnibus to horse car, from horse car to cable system, from the cable system to the electric car system, with special variations in the way of elevated railroads and pneumatic railways. Methods of lighting, heating, production and transference of power for motors, have passed through equal strides of change and improvement. Everything connected with the immense business of transportation, from the great undertaking of building a bridge or a steamship down to the sealing of a freight car or the excavation of a yard of rock, has in a like period passed through radical revolutions that are bewildering in their rapidity and in the greatness of the interests involved.

According to some critics, traditional armchair philosophical methodology relies in an illicit way on intuitions. But the particular structure of the critique is not often carefully articulated—a significant omission, since some of the critics’ arguments for skepticism about philosophy threaten to generalize to skepticism in general. More recently, some experimentalist critics have attempted to articulate a critique that is especially tailored to affect traditional methods, without generalizing too widely. Such critiques are more reasonable, and more worthy of serious consideration, than (...) are blunter critiques that generalize far too widely. I argue that a careful (empirical!) examination of extant philosophical practices shows that traditional philosophical methods can meet these more reasonable challenges. (shrink)

Our perceptual systems are not stagnant but can learn from experience. Why is this so? That is, what is the function of perceptual learning? I consider two answers to this question: The Offloading View, which says that the function of perceptual learning is to offload tasks from cognition onto perception, thereby freeing up cognitive resources (Connolly, 2019) and the Perceptual View, which says that the function of perceptual learning is to improve the functioning of perception. I argue that the Perceptual (...) View better explains data from infants and animals, and better accounts for learned tasks that only perception could perform. (shrink)

Do epistemic and aesthetic values ever conflict? The answer might appear to be no, given that background knowledge generally enhances aesthetic experience, and aesthetic experience in turn generates new knowledge. As Keats writes, ‘Beauty is truth, truth beauty’ (Keats, 1996). Contra this line of thought, I argue that epistemic and aesthetic values can conflict when we over-rely on aesthetically enhancing background beliefs. The true and the beautiful can pull in different directions, forcing us to choose between flavours of normativity.

Effective Altruism is a rapidly growing and influential contemporary philosophical movement committed to updating utilitarianism in both theory and practice. The movement focuses on identifying urgent but neglected causes and inspiring supererogatory giving to meet the need. It also tries to build a broader coalition by adopting a more ecumenical approach to ethics which recognizes a wide range of values and moral constraints. These interesting developments distinguish Effective Altruism from the utilitarianism of the past in ways that invite cooperation and (...) warrant a fresh look from Thomists. Nonetheless Effective Altruism’s fundamentally consequentialist and aggregative model for ethics precludes more foundational agreement with Thomistic ethics in ways that limit the extent of practical cooperation.
