BackgroundInnovations in technology have contributed to rapid changes in the way that modern biomedical research is carried out. Researchers are increasingly required to endorse adaptive and flexible approaches to accommodate these innovations and comply with ethical, legal and regulatory requirements. This paper explores how Dynamic Consent may provide solutions to address challenges encountered when researchers invite individuals to participate in research and follow them up over time in a continuously changing environment.MethodsAn interdisciplinary workshop jointly organised by the University of Oxford (...) and the COST Action CHIP ME gathered clinicians, researchers, ethicists, lawyers, research participants and patient representatives to discuss experiences of using Dynamic Consent, and how such use may facilitate the conduct of specific research tasks. The data collected during the workshop were analysed using a content analysis approach.ResultsDynamic Consent can provide practical, sustainable and future-proof solutions to challenges related to participant recruitment, the attainment of informed consent, participant retention and consent management, and may bring economic efficiencies.ConclusionsDynamic Consent offers opportunities for ongoing communication between researchers and research participants that can positively impact research. Dynamic Consent supports inter-sector, cross-border approaches and large scale data-sharing. Whilst it is relatively easy to set up and maintain, its implementation will require that researchers re-consider their relationship with research participants and adopt new procedures. (shrink)

This is the English (and extended version) of an interview originally published in Estonian in October 2018. In the interview, Simpson summarizes a particular way of defending the practice of no-platforming. The varying appeal of different defences of the practice in different socio-historical contexts (i.e. the UK/US versus a post-Soviet country such as Estonia) is discussed also.

Let ω be the set of natural numbers. For functions f, g: ω → ω, we say f is dominated by g if f < g for all but finitely many n ∈ ω. We consider the standard “fair coin” probability measure on the space 2ω of in-finite sequences of 0's and 1's. A Turing oracle B is said to be almost everywhere dominating if, for measure 1 many X ∈ 2ω, each function which is Turing computable from X is (...) dominated by some function which is Turing computable from B. Dobrinen and Simpson have shown that the almost everywhere domination property and some of its variant properties are closely related to the reverse mathematics of measure theory. In this paper we exposit some recent results of Kjos-Hanssen, Kjos-Hanssen/Miller/Solomon, and others concerning LR-reducibility and almost everywhere domination. We also prove the following new result: If B is almost everywhere dominating, then B is superhigh, i. e., 0″ is truth-table computable from B ′, the Turing jump of B. (shrink)

____Technology, Time, and the Conversations of Modernity__ takes as its impetus the idea that technology is an embodiment of our uneasiness with finitude. Lorenzo Simpson argues that technology has succeeded in granting our wish to domesticate time. He shows how this attitude affects our understanding of the meaning of action and our ability to discern meaning in our lives.

If any emergent historical criticism will tend by its own choice toward inclusiveness and eclecticism, it is also likely to be constrained by more subtle forms of complicity with the theoretical subculture within which it seeks its audience. It is not in principle impossible that we might choose to set going an initiative that is very different indeed from the methods and approaches already in place. But is nonetheless clear that we must be aware, in some propaedeutic way, of the (...) predispositions for or against such change that are latent in the horizons of the field as they are presently conceived and transmitted. An account of these predispositions will take up most of the following essay. Whether or not the particular texts I shall discuss constitute anything as firm as an establishment in the absolute sense does not matter much: they neither sum up the ongoing careers of their particular authors, in the diachronic sense, nor do they represent any simple totality in the critical culture of the late 1960s. All we need here is the weaker assumption: that these writings by Derrida, Paul de Man, Michel Foucault, and Pierre Macherey do offer, by virtue of their very notoriety, evidence of the priorities within the discipline that have afforded them their reputations in the first place. Thus, while they do not in themselves prohibit the emergence of alternatives, they do give us clues about the residual pressures that might constrain those alternatives, and they signal the questions that the historical party must respond to if it is to be recognized as making an important contribution to a debate. My argument will be that the influential critics of the late 1960s have made it very hard indeed to find a place for history, so much so that the avowedly Marxist alternative set forth by Jameson finds itself making disabling concessions to those very influences. I do not claim to describe the entire range of options and alternatives, and indeed offer no discussion of the most excitingly contested field of all, that represented by contemporary feminisms. I mean instead to demonstrate, through a reading of those methodologies that have become authoritative, that the status of historical inquiry has been so eroded that its reactive renaissance, in whatever form, threatens to remain merely gestural and generic. “History” promises thus to function as legitimating any reference to a context beyond literature exclusively conceived, whether it be one of discourse, biography, political or material circumstance. In particular, given the current popularity of discourse analysis, it seems likely that for many practitioners the historical method will remain founded in covertly idealist reconstructions.

Questions could and should be raised about the political profile of English Romanticism both in particular and in general. Wordsworth’s poetry is especially useful to me here because of the way in which, through formal discontinuities, it dramatizes political conflicts. Reacting against these discontinuities, aesthetically minded critics have simply tended to leave out of the canon those poems which have the greatest capacity to help us become aware of a political poetics. In this respect it may well be that Wordsworth (...) is the most stylistically perverse of the Romantic poets. Not the most difficult to read, necessarily—Percy Bysshe Shelley’s breath-suspending songs and William Blake’s determination to produce “variety in every line” with the aim of unfettering poetry surely make more aggressive and obvious demands on the reader.1 But in these cases we can be reasonably sure that the difficulties are part of a conscious and coherent intention to set imagination to work in kindling sparks from ashes. Wordsworth also set out to do this, and we can agree that he did so with some success in some poems. But critics from Samuel Taylor Coleridge onward have rightly questioned the unity of Wordsworth’s canon in this respect. In Biographia Literaria, Coleridge notices the “inconstancy of the style,” an unevenness and a general inability to satisfy the demands of “good poetry” conceived as something possessing an organic form.2 This concern with a wholeness and consistency of artifice is more Coleridge’s than Wordsworth’s, and it seems to me that it is precisely the disjunctions in the poems that embody some of their most original and historically urgent meanings. The blemishes recorded by Coleridge—alternating and dissimilar states of feeling, overminuteness in description, and obsession with “accidental circumstances” , overuse of the dramatic mode, disproportion of thought to event, and so forth—can in fact serve as eloquent signals for discerning the complexities of the poems as they address a historical crisis in consensus embodied exactly in the unstable vehicle of the Wordsworthian speaker.3 3.

Joshua DiPaolo and Robert Simpson on the origins of our beliefs and the problem of indoctrination.

This work on the theory of education was first published in 1839. The five writers had been chosen as the winners in a competition for an essay on the 'Expediency and Means of Elevating the Profession of the Educator in Society', organised by the Central Society of Education, founded in 1837 to promote state funding of education, at a time when the 'monitor' system, whereby older children taught younger ones, was seen as an effective method. The journalist John Lalor won (...) first prize with a wide-ranging consideration of all the aspects of education, comparing the status of teachers through history and across several countries, and championing their 'sacred mission'. The runners-up were the writer John A. Heraud, the Unitarian minister Edward Higginson, the lawyer and author James Simpson, and Mrs Sarah Porter, prolific writer on education and sister of the political economist David Ricardo. (shrink)

“Let me tell you where I'm coming from...”—so begins many a discussion in contemporary U.S. culture. Pressed by an almost compulsive desire to situate ourselves within a definite matrix of reference points in both scholarly inquiry and everyday parlance, we seem to reject adamantly the idea of a universal human subject. Yet what does this rhetoric of self-affiliation tell us? What is its history? David Simpson’s _Situatedness_ casts a critical eye on this currently popular form of identification, suggesting that, (...) far from being a simple turn of phrase, it demarcates a whole structure of thinking. Simpson traces the rhetorical syndrome through its truly interdisciplinary genealogy. Discussing its roles within the fields of legal theory, social science, fiction, philosophy, and ethics, he argues that the discourse of situatedness consists of a volatile fusion of modesty and aggressiveness. It oscillates, in other words, between accepting complete causal predetermination and advocating personal agency and responsibility. Simpson’s study neither fully rejects nor endorses the present-day language of self-specification. Rather it calls attention to the limitations and opportunities of situatedness—a notion whose ideological slippage it ultimately sees as allowing late-capitalist liberal democracies to function. Given its wide scope and lively rendering, _Situatedness_ will attract a range of scholars in the humanities and legal studies. It will also interest all those for whom the politics of subjectivity pose real problems of authority, identity, and belief. (shrink)

In this follow up to The Eudemian Ethics of Aristotle, Peter L. P. Simpson centers his attention on the basics of Aristotelian moral doctrine as found in the Great Ethics: the definition of happiness, the nature and kind of the virtues, pleasure, and friendship. This work’s authenticity is disputed, but Simpson argues that all the evidence favors it. Unlike the Nicomachean and Eudemian Ethics, Aristotle wrote the Great Ethics for a popular audience. It gives us insight less into (...) Aristotle the theoretician than into Aristotle the pedagogue.For this reason, the Great Ethics has distinct advantages as an introduction to Aristotelian ethical thinking: it is simpler and clearer in its argumentation, matters such as the intellectual virtues are made suitably secondary to the practical focus, the moral virtues come through with a pleasing directness, and the work’s syllogistic formalism gives it a transparency and accessibility that the other Ethics typically lack. Arius’ Epitome, which relies heavily on this work, helps confirm its value and authenticity.Because the Great Ethics is generally neglected by scholars, less has been done to clear up its obscurities or to expose its structure. But to ignore it is to lose another and more instructive way of approaching and appreciating Aristotle’s teaching. The translation is prefaced by an analytic outline of the whole, and the several sections of it are prefaced by brief summaries. The commentary supplies fuller descriptions and analyses, sorting out puzzles, removing misunderstandings, and resolving doubts of meaning and intention. This book is a fresh rendition of the work of the preeminent philosopher of all time. (shrink)

The purpose of this investigation is to extend earlier research on the relationship between corporate social and financial performance. The unique contribution of the study is the empirical analysis of a sample of companies from the banking industry and the use of Community Reinvestment Act ratings as a social performance measure. The empirical analysis solidly supports the hypothesis that the link between social and financial performance is positive.

Trust is difficult to define. Instead of doing so, I propose that the best way to understand the concept is through a genealogical account. I show how a root notion of trust arises out of some basic features of what it is for humans to live socially, in which we rely on others to act cooperatively. I explore how this concept acquires resonances of hope and threat, and how we analogically apply this in related but different contexts. The genealogical account (...) explains both why the notion has such value for us and why it is difficult to define. (shrink)

During human evolutionary history, there were “trade-offs” between expending time and energy on child-rearing and mating, so both men and women evolved conditional mating strategies guided by cues signaling the circumstances. Many short-term matings might be successful for some men; others might try to find and keep a single mate, investing their effort in rearing her offspring. Recent evidence suggests that men with features signaling genetic benefits to offspring should be preferred by women as short-term mates, but there are trade-offs (...) between a mate's genetic fitness and his willingness to help in child-rearing. It is these circumstances and the cues that signal them that underlie the variation in short- and long-term mating strategies between and within the sexes. Key Words: conditional strategies; evolutionary psychology; fluctuating asymmetry; mating; reproductive strategies; sexual selection. (shrink)

This paper examines two recent contributions to the hate speech literature – by Steven Heyman and Jeremy Waldron – which seek a justification for the legal restriction of hate speech in an account of the way that hate speech infringes against people’s dignity. These analyses look beyond the first-order hurts and disadvantages suffered by the immediate targets of hate speech, and consider the prospect of hate speech sustaining complex social structures whose wide-scale operations lower the social status of members of (...) targeted groups. In Heyman’s and Waldron’s accounts we find plausible insights into the nature of identity-based social hierarchies, and the harms that redound to subordinated people under the operations of such hierarchies. I argue, however, that both analyses are unsuccessful as justifications for the restriction of hate speech, because they do not ultimately provide reason to think that hate speech is responsible for creating or sustaining identity-based social hierarchies.

This article develops a social epistemological analysis of Web-based search engines, addressing the following questions. First, what epistemic functions do search engines perform? Second, what dimensions of assessment are appropriate for the epistemic evaluation of search engines? Third, how well do current search engines perform on these? The article explains why they fulfil the role of a surrogate expert, and proposes three ways of assessing their utility as an epistemic tool—timeliness, authority prioritisation, and objectivity. “Personalisation” is a current trend in (...) Internet-delivered services, and consists in tailoring online content to the interests of the individual user. It is argued here that personalisation threatens the objectivity of search results. Objectivity is a public good; so there is a prima facie case for government regulation of search engines. (shrink)

There is little empirical evidence showing a direct link between a capacity for statistical learning (SL) and proficiency with natural language. Moreover, discussion of the role of SL in language acquisition has seldom focused on literacy development. Our study addressed these issues by investigating the relationship between SL and reading ability in typically developing children and healthy adults. We tested SL using visually presented stimuli within a triplet learning paradigm and examined reading ability by administering the Wide Range Achievement Test (...) (WRAT-4; Wilkinson & Robertson, 2006). A total of 38 typically developing children (mean age of 9;5 years, range 6;4–12;5) and 37 healthy adults (mean age of 21 years, range 18–34) were assessed. In children, SL was significantly related to reading ability. Importantly, this relationship was independent of grade and also age. The adult data, too, revealed that SL was significantly related to reading ability. A regression analysis of the combined child and adult data revealed that SL accounted for a unique amount of variance in reading ability, after age and attention had been taken into consideration. For the first time, this study provides empirical evidence that a capacity for more effective SL is related to higher reading ability in the general population. (shrink)

We combine prior research on ethical decision-making in organizations with a rational choice theory of corporate crime from criminology to develop a model of corporate offending that is tested with a sample of U.S. managers. Despite demands for increased sanctioning of corporate offenders, we find that the threat of legal action does not directly affect the likelihood of misconduct. Managers’ evaluations of the ethics of the act, measured using a multidimensional ethics scale, have a significant effect, as do outcome expectancies (...) that result from being associated with the misconduct but not facing formal sanctions. The threat of formalsanctions appears to operate indirectly, influencing ethical evaluations and outcome expectancies. Obedience to authority also affects illegal intentions, with managers reporting higher prospective offending when they are ordered to engage in misconduct by a supervisor. (shrink)

A mass problem is a set of Turing oracles. If P and Q are mass problems, we say that P is weakly reducible to Q if every member of Q Turing computes a member of P. We say that P is strongly reducible to Q if every member of Q Turing computes a member of P via a fixed Turing functional. The weak degrees and strong degrees are the equivalence classes of mass problems under weak and strong reducibility, respectively. We (...) focus on the countable distributive lattices P w and P s of weak and strong degrees of mass problems given by nonempty Π 1 0 subsets of 2 ω . Using an abstract Gödel/Rosser incompleteness property, we characterize the Π 1 0 subsets of 2 ω whose associated mass problems are of top degree in P w and P s , respectively. Let R be the set of Turing oracles which are random in the sense of Martin-Löf, and let r be the weak degree of R. We show that r is a natural intermediate degree within P w . Namely, we characterize r as the unique largest weak degree of a Π 1 0 subset of 2 ω of positive measure. Within P w we show that r is meet irreducible, does not join to 1, and is incomparable with all weak degrees of nonempty thin perfect Π 1 0 subsets of 2 ω . In addition, we present other natural examples of intermediate degrees in P w . We relate these examples to reverse mathematics, computational complexity, and Gentzen-style proof theory. (shrink)

In disagreements about trivial matters, it often seems appropriate for disputing parties to adopt a ‘middle ground’ view about the disputed matter. But in disputes about more substantial controversies (e.g. in ethics, religion, or politics) this sort of doxastic conduct can seem viciously acquiescent. How should we distinguish between the two kinds of cases, and thereby account for our divergent intuitions about how we ought to respond to them? One possibility is to say that ceding ground in a trivial dispute (...) is appropriate because the disputing parties are usually epistemic peers within the relevant domain, whereas in a more substantial disagreement the disputing parties rarely, if ever, qualify as epistemic peers, and so ‘sticking to one’s guns’ is usually the appropriate doxastic response. My aim in this paper is to explain why this way of drawing the desired distinction is ultimately problematic, even if it seems promising at first blush. (shrink)

Softlifting (software piracy by individuals) is an unethical behavior that pervades today''s computer dependent society. Since a better understanding of underlying considerations of the behavior may provide a basis for remedy, a model of potential determinants of softlifting behavior is developed and tested. The analysis provides some support for the hypothesized model, specifically situational variables, such as delayed acquisition times, and personal gain variables, such as the challenge of copying, affect softlifting behavior. Most importantly, the analysis indicated that ethical perception (...) of softlifting has no significant affect on softlifting behavior. These findings suggest major implications for both software manufacturers and academicians attempting to reduce piracy behavior through ethics instruction. (shrink)

A mass problem is a set of Turing oracles. If P and Q are mass problems, we say that P is weakly reducible to Q if for all Y ∈ Q there exists X ∈ P such that X is Turing reducible to Y. A weak degree is an equivalence class of mass problems under mutual weak reducibility. Let [Formula: see text] be the lattice of weak degrees of mass problems associated with nonempty [Formula: see text] subsets of the Cantor (...) space. The lattice [Formula: see text] has been studied in previous publications. The purpose of this paper is to show that [Formula: see text] partakes of hyperarithmeticity. We exhibit a family of specific, natural degrees in [Formula: see text] which are indexed by the ordinal numbers less than [Formula: see text] and which correspond to the hyperarithmetical hierarchy. Namely, for each [Formula: see text], let hα be the weak degree of 0, the αth Turing jump of 0. If p is the weak degree of any mass problem P, let p* be the weak degree of the mass problem P* = {Y | ∃X ⊆ BLR )} where BLR is the set of functions which are boundedly limit recursive in X. Let 1 be the top degree in [Formula: see text]. We prove that all of the weak degrees [Formula: see text], [Formula: see text], are distinct and belong to [Formula: see text]. In addition, we prove that certain index sets associated with [Formula: see text] are [Formula: see text] complete. (shrink)

Early on in the development of Practicing Healthcare Ethicists Exploring Professionalization (PHEEP), the founding members recognized the need to address and meet two important goals: (1) the creation of a dynamic, rigorous process to support the exploratory work, and (2) the establishment of the means—deliberative engagement—to generate and justify the substantive content of professionalization-related products, such as practice standards and position statements. Drawing from social justice and deliberative democracy conceptions and insights (among others), the authors identify and describe the core (...) elements of the “process scaffolding” and “deliberative means” that inform PHEEP’s deliberative engagement methodology. The paper demonstrates how these process and substantive features have been meaningfully instantiated in the decision making framework established by PHEEP for its use in the development of professionalization-related products by Canadian practicing healthcare ethicists.

We investigate the provability or nonprovability of certain ordinary mathematical theorems within certain weak subsystems of second order arithmetic. Specifically, we consider the Cauchy/Peano existence theorem for solutions of ordinary differential equations, in the context of the formal system RCA 0 whose principal axioms are ▵ 0 1 comprehension and Σ 0 1 induction. Our main result is that, over RCA 0 , the Cauchy/Peano Theorem is provably equivalent to weak Konig's lemma, i.e. the statement that every infinite {0, 1}-tree (...) has a path. We also show that, over RCA 0 , the Ascoli lemma is provably equivalent to arithmetical comprehension, as is Osgood's theorem on the existence of maximum solutions. At the end of the paper we digress to relate our results to degrees of unsolvability and to computable analysis. (shrink)

This paper considers the phenomenon of lying and the implications it has for those subjects who are capable of lying. It is argued that lying is not just intentional untruthfulness, but is intentional untruthfulness plus an insincere invocation of trust. Understood in this way, lying demands of liars a sophistication in relation to themselves, to language, and to those to whom they lie which exceeds the demands on mere truth-tellers.

Voluntary management standards for social and environmental performance ideally help to define and improve firms’ related capabilities. These standards, however, have largely failed to improve such performance as intended. Over-emphasis on institutional factors leading to adoption of these standards has neglected the role of firms’ existing capabilities. External pressures can drive firms to adopt standards more than their technical capacity to employ them. This can lead to problems of “fit” between institutional requirements and a firm’s existing capabilities . We describe (...) a conceptual model that considers the impact of an interaction between a firm’s institutional requirements and its existing capabilities on standards failure. We suggest solutions that align institutional requirements to appropriate governance forms as a means to improve standards success. We contribute to theory by describing the role of firms’ internal capabilities to the success of voluntary management standards and the reliability of self-regulation generally. (shrink)

There are several important conceptual issues and questions about the practice of healthcare ethics that can, and should, inform the development of any practice standards. This paper provides a relatively short overview of seven of these issues, with the invitation for further critical reflection and examination of their relevance to and implications for practice standards. The seven issues described include: diversity (from the perspective of training and experience); moral expertise and authority/influence; being an insider or outsider; flexibility and adaptability (for (...) local contexts of practice); the relative weighting of procedural and normative aspects of ethics practice; making mistakes or errors; and conflicts of interest in practice.

activity” has been considered to play a major role in the short-term maintenance of memories. Many studies since then have provided support for this view and greatly advanced our knowledge of the effects of stimulus type and modality on delay activity and its temporal dynamics.

The published findings include reports of systematic changes (...) in signal amplitude during working memory in the theta, alpha, beta. (shrink)

If internalism in ethics is correct, then moral beliefs necessarily motivate. Externalism rejects this thesis, holding that the relationship between beliefs and motives is only contingent. The position I develop is that both views are false. By defining a logical relationship between moral beliefs and motives that is weaker than logical necessitation, it is possible to maintain (contrary to internalism) that beliefs may occur without motives, but (contrary to externalism) that they cannot always do so. The logical point is explicated (...) through a psychological interpretation of moral emotions that gives their constituent beliefs an inherent link to action, together with a semantic characterization of moral concepts that ties their competent use to familiarity with these emotions.

We initiate the reverse mathematics of general topology. We show that a certain metrization theorem is equivalent to Π2 1 comprehension. An MF space is defined to be a topological space of the form MF(P) with the topology generated by $\lbrace N_p \mid p \in P \rbrace$ . Here P is a poset, MF(P) is the set of maximal filters on P, and $N_p = \lbrace F \in MF(P) \mid p \in F \rbrace$ . If the poset P is countable, (...) the space MF(P) is said to be countably based. The class of countably based MF spaces can be defined and discussed within the subsystem ACA0 of second order arithmetic. One can prove within ACA0 that every complete separable metric space is homeomorphic to a countably based MF space which is regular. We show that the converse statement, "every countably based MF space which is regular is homeomorphic to a complete separable metric space," is equivalent to Π2 1-CA0. The equivalence is proved in the weaker system Π1 1-CA0. This is the first example of a theorem of core mathematics which is provable in second order arithmetic and implies Π2 1 comprehension.

Let X be a compact metric space. A closed set K $\subseteq$ X is located if the distance function d(x, K) exists as a continuous real-valued function on X; weakly located if the predicate d(x, K) $>$ r is Σ 0 1 allowing parameters. The purpose of this paper is to explore the concepts of located and weakly located subsets of a compact separable metric space in the context of subsystems of second order arithmetic such as RCA 0 , WKL (...) 0 and ACA 0 . We also give some applications of these concepts by discussing some versions of the Tietze extension theorem. In particular we prove an RCA 0 version of this result for weakly located closed sets.

In Humanity’s End: Why We Should Reject Radical Enhancement, Nicholas Agar presents a novel argument against the prospect of radical life-extension. Agar’s argument hinges on the claim that extended lifespans will result in people’s lives being dominated by the fear of death. Here we examine this claim and the surrounding issues in Agar’s discussion. We argue, firstly, that Agar’s view rests on empirically dubious assumptions about human rationality and attitudes to risk, and secondly, that even if those assumptions are granted, (...) the fears that Agar adverts to are unlikely to dominate people’s lives if and when radical life-extension is made possible. Further, we claim that the structure of the decision-making process around life-extension is unlikely to be the way that it would have to be in order for Agar’s claims about fear of death to make sense. Finally, we argue that Agar is implicitly committed to a narrow conception of human value. In response, we suggest that the pursuit of life-extension can itself be seen as an expression of certain important aspects of our distinctively human nature. (shrink)

I address the assumption that communicative interaction is made possible by knowledge of a language. I argue that this assumption as it is usually expressed depends on an unjustified reification of language, and on an unsatisfactory understanding of ‘knowledge’. I propose instead that communicative interaction is made possible by (Rylean) know-how and by the development of (Davidsonian) passing theories. We then come to see that our focus ought to be, not on propositional knowledge of a language which we internally represent, (...) but on the practical application of know-how in our understanding and interpretation of others.

The question of whether lies by those who govern are acceptable receives a clear focus and an ideal case in the Republic. Against C. D. C. Reeve, and T. C. Brickhouse and N.

While lies may be a necessary part of the City’s administration, the process and practice of lying undermines that nature which is necessary for any suitable ruler – rendering the ideal impossible. I argue (...) that this analysis, while concerned with an ideal case, also applies to the political realist’s regrettable-but-necessary defence of such practices. (shrink)

Why are people trustworthy? I argue for two theses. First, we cannot explain many socially important forms of trustworthiness solely in terms of the instrumentally rational seeking of one’s interests, in response to external sanctions or rewards. A richer psychology is required. So, second, possession of moral character is a plausible explanation of some socially important instances when people are trustworthy. I defend this conclusion against the influential account of trust as ‘encapsulated interest’, given by Russell Hardin, on which most (...) trustworthiness is explained by the interest of continuing relationship.

Putting robots on the battlefield is clearly appealing for policymakers. Why risk human lives, when robots could take our place, and do the dirty work of killing and dying for us? Against this, I argue that robots will be unable to win the kind of wars that we are increasingly drawn into. Modern warfare tends towards asymmetric conflict. Asymmetric warfare cannot be won without gaining the trust of the civilian population; this is ‘the hearts and minds’, in the hackneyed phrase (...) from counter-insurgency manuals. I claim that the very feature which makes it attractive to send robots to war in our place, the absence of risk, also makes it peculiarly difficult for humans to trust them. Whatever the attractions, sending robots to war in our stead will make success in counter-insurgency elusive. Moreover, there is ethical reason to be relieved at this conclusion. For if war is potentially costly, then this does much to ensure that it will be a choice only of last resort, in accordance with the traditional doctrine of jus ad bellum. In this instance, morality and expediency— fortunately— coincide. (shrink)
