There has been a recent surge of research interest in videogames of moral engagement for entertainment, advocacy and education. We have seen a wealth of analysis and several theoretical models proposed, but experimental evaluation has been scarce. One of the difficulties lies in the measurement of moral engagement. How do we meaningfully measure whether players are engaging with and affected by the moral choices in the games they play? In this paper, we survey the various standard psychometric instruments from the (...) moral psychology literature and discuss how they might be applied in the evaluation of games. (shrink)

Historically the focus of moral decision-making in games has been narrow, mostly confined to challenges of moral judgement (deciding right and wrong). In this paper, we look to moral psychology to get a broader view of the skills involved in ethical behaviour and how these skills can be employed in games. Following the Four Component Model of Rest and colleagues, we identify four “lenses” – perspectives for considering moral gameplay in terms of focus, sensitivity, judgement and action – and describe (...) the design problems raised by each. To conclude, we analyse two recent games, The Walking Dead and Papers, Please, and show how the lenses give us insight into important design differences between these games. (shrink)

As robots and Artificial Intelligences become more enmeshed in rich social contexts, it seems inevitable that we will have to make them into moral machines equipped with moral skills. Apart from the technical difficulties of how we could achieve this goal, we can also ask the ethical question of whether we should seek to create such Artificial Moral Agents (AMAs). Recently, several papers have argued that we have strong reasons not to develop AMAs. In response, we develop a comprehensive analysis (...) of the relevant arguments for and against creating AMAs, and we argue that all things considered we have strong reasons to continue to responsibly develop AMAs. The key contributions of this paper are threefold. First, to provide the first comprehensive response to the important arguments made against AMAs by Wynsberghe and Robbins (in “Critiquing the Reasons for Making Artificial Moral Agents”, Science and Engineering Ethics 25, 2019) and to introduce several novel lines of argument in the process. Second, to collate and thematise for the first time the key arguments for and against AMAs in a single paper. Third, to recast the debate away from blanket arguments for or against AMAs in general, to a more nuanced discussion about the use of what sort of AMAs, in what sort of contexts, and for what sort of purposes is morally appropriate.

This special issue of Games and Culture focuses on the intersection between video games and ethics. This introduction briefly sets out the key research questions in the research field and identifies trends in the articles included in this special issue.

According to cognitive psychologists, moral decision-making is a dual-process phenomenon involving two types of cognitive processes: explicit reasoning and implicit intuition. Moral development involves training and integrating both types of cognitive processes through a mix of instruction, practice, and reflection. Serious games are an ideal platform for this kind of moral training, as they provide safe spaces for exploring difficult moral problems and practicing the skills necessary to resolve them. In this article, we present Morality Play, a model for the (...) design of serious games for ethical expertise development based on the Integrative Ethical Education framework from moral psychology and the Lens of the Toy model for serious game design.

Morality meters are a commonly used mechanic in many ethically notable video games. However, there have been several theoretical critiques of such meters, including that people can find them alienating, they can instrumentalise morality, and they reduce morality to a binary of good and evil with no room for complexity. While there has been much theoretical discussion of these issues, there has been far less empirical investigation. We address this gap through a qualitative study that involved participants playing a custom-built (...) visual novel game (The Great Fire) with different intuitive and counter-intuitive morality meter settings. Overall, we found that players’ attitudes towards the morality meter in this game was complex, context sensitive and variable throughout gameplay and that the intuitiveness of the meter encouraged participants to treat the meter more ‘as a moral guide’ that prompts reflection and less ‘as a score’ to be engaged with reactively.

BackgroundThe ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines are widely endorsed but compliance is limited. We sought to determine whether journal-requested completion of an ARRIVE checklist improves full compliance with the guidelines.MethodsIn a randomised controlled trial, manuscripts reporting in vivo animal research submitted to PLOS ONE (March–June 2015) were randomly allocated to either requested completion of an ARRIVE checklist or current standard practice. Authors, academic editors, and peer reviewers were blinded to group allocation. Trained reviewers performed outcome adjudication (...) in duplicate by assessing manuscripts against an operationalised version of the ARRIVE guidelines that consists 108 items. Our primary outcome was the between-group differences in the proportion of manuscripts meeting all ARRIVE guideline checklist subitems.ResultsWe randomised 1689 manuscripts (control: n = 844, intervention: n = 845), of which 1269 were sent for peer review and 762 (control: n = 340; intervention: n = 332) accepted for publication. No manuscript in either group achieved full compliance with the ARRIVE checklist. Details of animal husbandry (ARRIVE subitem 9b) was the only subitem to show improvements in reporting, with the proportion of compliant manuscripts rising from 52.1 to 74.1% (X2 = 34.0, df = 1, p = 2.1 × 10−7) in the control and intervention groups, respectively.ConclusionsThese results suggest that altering the editorial process to include requests for a completed ARRIVE checklist is not enough to improve compliance with the ARRIVE guidelines. Other approaches, such as more stringent editorial policies or a targeted approach on key quality items, may promote improvements in reporting. (shrink)

The ‘Ordinary Language’ philosophy of the early 20th century is widely thought to have failed. It is identified with the broader so-called ‘linguistic turn’, a common criticism of which is captured by Devitt and Sterelny (1999), who quip: “When the naturalistic philosopher points his finger at reality, the linguistic philosopher discusses the finger.” (p 280) The implication is that according to ‘linguistic’ philosophy, we are not to study reality or truth or morality etc, but the meaning of the words ‘reality’, (...) ‘truth’, ‘morality’ etc. Ordinary Language philosophy has fallen so thoroughly into disrepute because it is supposed to advocate that not only are we to study words and meanings rather than the phenomena themselves (which is apparently bad enough), but we must restrict that study to words and meanings as they occur in the language used by the ordinary speaker. A number of preposterous corollaries have been taken to follow from this view. Most seriously, perhaps, and irritatingly, is that any theory which contains ‘non-ordinary’ uses of expressions is thereby ‘meaningless’ or simply false – which is clearly absurd. In this paper I show that this is a completely inaccurate picture of Ordinary Language philosophy. My aim is to correct these persistent misinterpretations, and make possible a more sensible reassessment of the philosophy. (shrink)

For Ordinary Language philosophy, at issue is the use of the expressions of language, not expressions in and of themselves. So, at issue is not, for example, ordinary versus (say) technical words; nor is it a distinction based on the language used in various areas of discourse, for example academic, technical, scientific, or lay, slang or street discourses – ordinary uses of language occur in all discourses. It is sometimes the case that an expression has distinct uses within distinct discourses, (...) for example, the expression ‘empty space’. This may have both a lay and a scientific use, and both uses may count as ordinary; as long as it is quite clear which discourse is in play, and thus which of the distinct uses of the expression is in play. Though connected, the difference in use of the expression in different discourses signals a difference in the sense with which it is used, on the Ordinary Language view. One use, say the use in physics, in which it refers to a vacuum, is distinct from its lay use, in which it refers rather more flexibly to, say, a room with no objects in it, or an expanse of land with no buildings or trees. However, on this view, one sense of the expression, though more precise than the other, would not do as a replacement of the other term; for the lay use of the term is perfectly adequate for the uses it is put to, and the meaning of the term in physics would not allow speakers to express what they mean in these other contexts.

This is the first in a series of occasional volumes of original papers on predefined themes. The Mind Association will nominate an editor or editors for each collection, and may join with other organizations in the promotion of conferences or other scholarly activities in connection with each volume. This collection, published to coincide with the 400th anniversary of Thomas Hobbes's birth, focuses on central themes in his life and work. Including essays by David Gauthier, Noel Malcolm, Arrigo Pacchi, David (...) Raphael, Tom Sorrell, Francois Tricaud, and Richard Tuck, the book testifies to Hobbes's enduring importance as a major philosopher and helps to unravel those aspects of his intellectual biography that are relevant to a proper appreciation of his philosophy.

Ryan Johnson and Biko Mandela Gray study the relationship between Hegel's Phenomenology of Spirit and Black Thought from Frederick Douglass to Angela Davis. This staging of an elongated dialectical parallelism between Hegel's classic text and major 19th-20th-century Black thinkers explodes the western canon of philosophy. Johnson and Mandela Gray show that Hegel's abstract dialectic is transformed and critiqued when put into conversation with the lived dialectics of Black Thought: from Frederick Douglass and Harriet Jacobs through to Malcolm X (...) and Angela Davis. While Hegel articulates the dynamic logics that we see in these Black thinkers, when they are placed in parallel and considered together, the whiteness, both explicit and implicit, of Hegelianism itself is revealed. Forcing Hegelianism into the embodied history of Black Thought reveals a phenomenology of America whose spirit is Black. (shrink)

In this paper we argue that there is a kind of moral disagreement that survives the Rawlsian veil of ignorance. While a veil of ignorance eliminates sources of disagreement stemming from self-interest, it does not do anything to eliminate deeper sources of disagreement. These disagreements not only persist, but transform their structure once behind the veil of ignorance. We consider formal frameworks for exploring these differences in structure between interested and disinterested disagreement, and argue that consensus models offer us a (...) solution concept for disagreements behind the veil of ignorance.

The 21st century is the time of complexity. We delineate it and its importance as necessary to solve ‘wicked problems.’ Inherently transdisciplinary, trans-scale, and interconnected to living systems, the solution to Heliophysics’ identity crisis and to unlock the next generation of scientific discovery may be to embrace complexity. With the right foresight, direction, and incentive over the next ten years, Heliophysics can become a beacon for how all of society thinks about and does complexity science.

The influence of prior familiarity with components on the implicit learning of relations was examined using artificial grammar learning. Prior to training on grammar strings, participants were familiarised with either the novel symbols used to construct the strings or with irrelevant geometric shapes. Participants familiarised with the relevant symbols showed greater accuracy when judging the correctness of new grammar strings. Familiarity with elemental components did not increase conscious awareness of the basis for discriminations but increased accuracy even in its absence. (...) The subjective familiarity of test strings predicted grammaticality judgments. However, prior exposure to relevant symbols did not increase overall test string familiarity or reliance on familiarity when making grammaticality judgments. Familiarity with the symbols increased the learning of relations between them thus resulting in greater familiarity for grammatical versus ungrammatical strings. The results have important implications for models of implicit learning. (shrink)

Noel Malcolm, one of the world's leading experts on Thomas Hobbes, presents a set of extended essays on a wide variety of aspects of the life and work of this giant of early modern thought. Malcolm offers a succinct introduction to Hobbes's life and thought, as a foundation for his discussion of such topics as his political philosophy, his theory of international relations, the development of his mechanistic world-view, and his subversive Biblical criticism. Several of the essays pay (...) special attention to the European dimensions of Hobbes's life, his sources and his influence; the longest surveys the entire European reception of his work from the 1640s to the 1750s. All the essays are based on a deep knowledge of primary sources, and many present striking new discoveries about Hobbes's life, his manuscripts, and the printing history of his works. Aspects of Hobbes will be essential reading not only for Hobbes specialists, but also for all those interested in seventeenth-century intellectual history more generally, both British and European.

This paper explores the space of possibilities for public justification in morally diverse communities. Moral diversity is far more consequential than is typically appreciated, and as a result, we need to think more carefully about how our standard tools function in such environments. I argue that because of this diversity, public justification can be divorced from any claim of determinateness. Instead, we should focus our attention on procedures—in particular, what Rawls called cases of pure procedural justice. I use a modified (...) form of the procedure “I cut, you choose” to demonstrate how perspectival diversity can make what looks like a simple procedure quite complex in practice. I use this to reframe disputes between classical liberal and contemporary liberal approaches to questions of public morality, arguing that classically liberal procedures, such as a reliance on the harm principle, can generate rather illiberal-looking outcomes when used in a morally diverse community. A seemingly less-principled approach, which simply balances burdens, appears to generate outcomes that look closer to what we would expect from classical liberalism. However, since both approaches are based on pure procedures that we can justify without reference to outcomes, it remains indeterminate which we ought to choose. (shrink)

This is a paper about the nature of metaphysical laws and their relation to the phenomenon of vagueness. Metaphysical laws are introduced as analogous to natural laws, and metaphysical indeterminism is modeled on causal indeterminacy. This kind of indeterminacy is then put to work in developing a novel theory of vagueness and a solution to the sorites paradox.

William Whewell’s philosophy of scientific discovery is applied to the problem of understanding the nature of unification and explanation by the composition of causes in Newtonian mechanics. The essay attempts to demonstrate: the sense in which ”approximate’ laws successfully refer to real physical systems rather than to idealizations of them; why good theoretical constructs are not badly underdetermined by observation; and why, in particular, Newtonian forces are not conventional and how empiricist arguments against the existence of component causes, and against (...) the veracity of the fundamental laws, are flawed.

The Eleatic philosophers argued that it was impossible for anything to change, since that would require something to differ from itself. Although this line of reasoning is unpersuasive, it challenges us to provide an account of temporal predication, which is the focus of much recent work on change. This paper surveys various approaches to change and temporal predication and addresses related questions about identity, persistence, properties, time, tense, and temporal logic.

David Lewis has long defended an analysis of counterfactuals in terms of comparative similarity of possible worlds. The purpose of this paper is to reevaluate Lewis’s response to one of the oldest and most familiar objections to this proposal, the future similarity objection.

There are two intriguing paradoxes in molecular biology-the inconsistent relationship between organismal complexity and (1) cellular DNA content and (2) the number of protein-coding genes-referred to as the C-value and G-value paradoxes, respectively. The C-value paradox may be largely explained by varying ploidy. The G-value paradox is more problematic, as the extent of protein coding sequence remains relatively static over a wide range of developmental complexity. We show by analysis of sequenced genomes that the relative amount of non-protein-coding sequence increases (...) consistently with complexity. We also show that the distribution of introns in complex organisms is non-random. Genes composed of large amounts of intronic sequence are significantly overrepresented amongst genes that are highly expressed in the nervous system, and amongst genes downregulated in embryonic stem cells and cancers. We suggest that the informational paradox in complex organisms may be explained by the expansion of cis-acting regulatory elements and genes specifying trans-acting non-protein-coding RNAs. (shrink)

In Aristotle's view, Anaxagoras stood out from the other Presocratics as a sober man among the incoherent. This book explores the fragmentary evidence both for Anaxagoras' concept of mind - to which Aristotle was particularly referring - and for his subtle, complex and elusive theory of matter and change. It is concerned with two aspects of his writing in particular: its comparatively high ratio of dogmatic assertion to argument, and a pervasive ambiguity or indeterminacy in the presentation of Anaxagoras' philosophical (...) theses. The problems posed by Anaxagoras' work are examined not only by means of philosophical comparison with what survives of other Presocratics, but in the light of the development of the prose book as a vehicle for the communication of ideas in early Greece. A book for the scholar of ancient philosophy. (shrink)

The word euboulia, which means excellence in counsel or sound judgement, occurs in only three places in the authentic writings of Plato. The sophist Protagoras makes euboulia the focus of his whole enterprise : What I teach a person is good judgement about his own affairs — how best he may manage his own household; and about the affairs of the city — how he may be most able to handle the business of the city both in action and in (...) speech. Thrasymachus, too, thinks well of euboulia. Invited by Socrates to call injustice kakoetheia ’, i.e. as simple-mindedness), he declines the sophistry and says : ‘No, I call it good judgement’. But Plato finds little occasion to introduce the concept in developing his own ethical and political philosophy. The one place where he mentions euboulia is in his defence of the thesis that his ideal city possesses the four cardinal virtues. He begins with wisdom, and justifies the ascription of wisdom to the city on the ground that it has euboulia — which he goes on to identify with the knowledge required by the guardians: ‘with this a person does not deliberate on behalf of any of the elements in the city, but for the whole city itself — how it may best have dealings with itself and with the other cities’ . It is normally rather dangerous to draw an inference from the absence or rarity of a word to the absence or rarity of the idea expressed by the word. (shrink)

The philosophical tradition of liberal political thought has come to see tolerance as a crucial element of a liberal political order. However, while much has been made of the value of toleration, little work has been done on individual-level motivations for tolerant behavior. In this article, we seek to develop an account of the rational motivations for toleration and of where the limits of toleration lie. We first present a very simple model of rational motivations for toleration. Key to this (...) model is an application of David Ricardo’s model of trade to thinking about toleration. This model supports the claim that we always have reasons to be as tolerant as possible. We then explore why we do not always see tolerant attitudes in the actual world, and point to some potential preconditions for toleration that the initial model does not capture. Subsequently, we examine a more detailed model that allows us to investigate more carefully the conditions under which tolerant behavior can be rewarded. We conclude by arguing that a consideration of self-interested motivations for toleration is essential to the success of a robust theory of toleration for a diverse society, but that even this approach has its limitations.

In Perceiving God, William Alston briefly suggests the possibility of perceiving God indirectly through the perception of another object. Following recent work by C. Stephen Evans, we argue that Thomas Reid’s notion of “natural signs” helpfully illuminates how people can perceive God indirectly through natural beauty. First, we explain how some natural signs enable what Alston labels “indirect perception.” Second, we explore how certain emotions make it possible to see both beauty and the excellence of the minds behind beauty. Finally, (...) we explain how aesthetic emotions can involve indirect perception of God via the natural sign of natural beauty. (shrink)

Page's “localist” code, a population code with occasional, maximally firing elements, does not seem to us usefully or testably different from sparse population coding. Some of the evidence adduced by Page for his proposal is not actually evidence for it, and coding by maximal firing is challenged by lower firing observed in neuronal responses to natural stimuli.

In this paper I argue that the stretch of dialogue from 385 b 2–d 1 in the Cratylus does not belong where it is found in the MSS. , but fits rather between 387 c 5 and 387 c 6. I suggest further that at any rate my negative thesis receives some measure of support from the fragments of Proclus' commentary on the dialogue.

Abstract Semi-autonomous robotic weapons are already carving out a role for themselves in modern warfare. Recently, Ronald Arkin has argued that autonomous lethal robotic systems could be more ethical than humans on the battlefield, and that this marks a significant reason in favour of their development and use. Here I offer a critical response to the position advanced by Arkin. Although I am sympathetic to the spirit of the motivation behind Arkin's project and agree that if we decide to develop (...) and use these machines they ought to be programmed to behave ethically, there are several major problems with his view as it stands. At present, it is not clear whether such machines would be capable of behaving more ethically than humans. More importantly, to the extent that humans would remain in the context of war, human moral transgressions will continue, especially in the face of complicated ethical challenges accompanying automated warfare. Moreover, even if machines could be more ethical than humans in certain ways and in certain situations, this says nothing about whether warfare that contains these machines would itself be overall more ethical than warfare that does not include them as participants, or whether the inclusion of lethal robots is the best way to guard against human moral transgressions in war.

This case concerns aspects of the treatment of a post-surgical patient in a major public hospital in New Zealand during the author's experiences as a fourth year medical student. This case is used to consider the interlinked ethical issues of sympathy, moral virtue, dignity and how the medical environment can realign these values.
