There are fundamental differences between the explanation of scientific change and the explanation of technological change. The differences arise from fundamental differences between scientific and technological knowledge and basic disanalogies between technological advance and scientific progress. Given the influence of economic markets and industrial and institutional structures on the development of technology, it is more plausible to regard technological change as a continuous and incremental process, rather than as a process of Kuhnian crises and revolutions.

In Pragmatism’s Evolution, Trevor Pearce demonstrates that the philosophical tradition of pragmatism owes an enormous debt to specific biological debates in the late 1800s, especially those concerning the role of the environment in development and evolution. Many are familiar with John Dewey’s 1909 assertion that evolutionary ideas overturned two thousand years of philosophy—but what exactly happened in the fifty years prior to Dewey’s claim? What form did evolutionary ideas take? When and how were they received by American philosophers? Although (...) the various thinkers associated with pragmatism—from Charles Sanders Peirce to Jane Addams and beyond—were towering figures in American intellectual life, few realize the full extent of their engagement with the life sciences. In his analysis, Pearce focuses on a series of debates in biology from 1860 to 1910—from the instincts of honeybees to the inheritance of acquired characteristics—in which the pragmatists were active participants. If we want to understand the pragmatists and their influence, Pearce argues, we need to understand the relationship between pragmatism and biology. (shrink)

This paper provides a new analysis of e - trust , trust occurring in digital contexts, among the artificial agents of a distributed artificial system. The analysis endorses a non-psychological approach and rests on a Kantian regulative ideal of a rational agent, able to choose the best option for itself, given a specific scenario and a goal to achieve. The paper first introduces e-trust describing its relevance for the contemporary society and then presents a new theoretical analysis of this phenomenon. (...) The analysis first focuses on an agent’s trustworthiness , this one is presented as the necessary requirement for e-trust to occur. Then, a new definition of e-trust as a second-order-property of first-order relations is presented. It is shown that the second-order-property of e-trust has the effect of minimising an agent’s effort and commitment in the achievement of a given goal. On this basis, a method is provided for the objective assessment of the levels of e-trust occurring among the artificial agents of a distributed artificial system. (shrink)

We think less than we think. My thesis moves from this suspicion to show that standard accounts of intentional action can't explain the whole of agency. Causalist accounts such as Davidson's and Bratman's, according to which an action can be intentional only if it is caused by a particular mental state of the agent, don't work for every kind of action. So-called automatic actions, effortless performances over which the agent doesn't deliberate, and to which she doesn't need to pay attention, (...) constitute exceptions to the causalist framework, or so I argue in this thesis. Not all actions are the result of a mental struggle, painful hesitation, or the weighting of evidence. Through practice, many performances become second nature. Think of familiar cases such as one's morning routines and habits: turning on the radio, brushing your teeth. Think of the highly skilled performances involved in sport and music: Jarrett's improvised piano playing, the footballer's touch. Think of agents' spontaneous reactions to their environment: ducking a blow, smiling. Psychological research has long acknowledged the distinctiveness and importance of automatic actions, while philosophy has so far explained them together with the rest of agency. Intuition tells us that automatic actions are intentional actions of ours all the same (I have run a survey which shows that this intuition is widely shared): not only our own autonomous deeds for which we are held responsible, but also necessary components in the execution and satisfaction of our general plans and goals. But do standard causal accounts deliver on the intentionality of automatic actions? I think not. Because, in automatic cases, standard appeals to intentions, beliefs, desires, and psychological states in general ring hollow. We just act: we don't think, either consciously or unconsciously. On the reductive side, Davidson's view can't but appeal to, at best, unconscious psychological states, the presence and causal role of which is, I argue, inferred from the needs of a theory, rather than from evidence in the world. On the non-reductive side, Bratman agrees, with his refutation of the Simple View, that we can't just attach an intention to every action that we want to explain. But Bratman’s own Single Phenomenon View, appealing to the mysterious notion of 'motivational potential', merely acknowledges the need for refinement without actually providing one. So I propose my own account of intentional action, the 'guidance view', according to which automatic actions are intentional: differently from Davidson and Bratman, who only offer necessary conditions in order to avoid the problem of causal deviance, I offer a full-blown account: E's phi-ing is intentional if and only If phi-ing is under E's guidance. This account resembles one developed by Frankfurt, with the crucial difference that Frankfurt – taking 'acting with an intention' and 'acting intentionally' to be synonymous – thinks that guidance is sufficient only for some movement being an action, but not for some movement being an intentional action. I argue that, on the other hand, Frankfurt's concept of guidance can be developed so that it is sufficient for intentional action too. In Chapter One I present and defend my definition of ‘automatic action’. In Chapter Two I show that such understanding of automatic actions finds confirmation in empirical psychology. In Chapter Three I show that Davidson's reductive account of intentional action does not work for automatic actions. In Chapter Four I show that the two most influential non-reductive accounts of intentional action, the Simple View and Bratman's Single Phenomenon View, don't work either. And in Chapter Five I put forward and defend my positive thesis, the 'guidance view'. Also, in the Appendix I present the findings of my survey on the intentionality of automatic actions. (shrink)

In this article I propose an ethical analysis of information warfare, the warfare waged in the cyber domain. The goal is twofold: filling the theoretical vacuum surrounding this phenomenon and providing the conceptual grounding for the definition of new ethical regulations for information warfare. I argue that Just War Theory is a necessary but not sufficient instrument for considering the ethical implications of information warfare and that a suitable ethical analysis of this kind of warfare is developed when Just War (...) Theory is merged with Information Ethics. In the initial part of the article, I describe information warfare and its main features and highlight the problems that arise when Just War Theory is endorsed as a means of addressing ethical problems engendered by this kind of warfare. In the final part, I introduce the main aspects of Information Ethics and define three principles for a just information warfare resulting from the integration of Just War Theory and Information Ethics.

In this article, I offer an outline of the papers comprising the special issue. I also provide a brief overview of its topic, namely, the friction between cyber security measures and individual rights. I consider such a friction to be a new and exacerbated version of what Mill called ‘the struggle between liberties and authorities,’ and I claim that the struggle arises because of the involvement of public authorities in the management of the cyber sphere, for technological and state power (...) can put individual rights, such as privacy, anonymity and freedom of speech, under sharp devaluating pressure. Finally, I conclude by stressing the need to reach an ethical balance to fine-tune cyber security measures and individual rights. (shrink)

I argue against Appel's recent proposal – in this JOURNAL – that there is a fundamental human right to sexual pleasure, and that therefore the sexual pleasure of severely disabled people should be publicly funded – by thereby partially legalizing prostitution. I propose an alternative that does not need to pose a new positive human right; does not need public funding; does not need the legalization of prostitution; and that would offer a better experience to the severely disabled: charitable non-profit (...) organizations whose members would voluntarily and freely provide sexual pleasure to the severely disabled.

In this paper I refute an apparently obvious objection to Frankfurt-type counterexamples to the Principle of Alternate Possibilities according to which if in the counterfactual scenario the agent does not act, then the agent could have avoided acting in the actual scenario. And because what happens in the counterfactual scenario cannot count as the relevant agent's actions given the sort of external control that agent is under, then we can ground responsibility on that agent having been able to avoid acting. (...) I illustrate how this objection to Frankfurt's famous counterexample is motivated by Frankfurt's own 'guidance' view of agency. My argument consists in showing that even if we concede that the agent does not act in the counterfactual scenario, that does not show that the agent could have avoided acting in the actual scenario. This depends on the crucial distinction between 'not φ-ing' and 'avoiding φ-ing'. (shrink)

Online service providers —such as AOL, Facebook, Google, Microsoft, and Twitter—significantly shape the informational environment and influence users’ experiences and interactions within it. There is a general agreement on the centrality of OSPs in information societies, but little consensus about what principles should shape their moral responsibilities and practices. In this article, we analyse the main contributions to the debate on the moral responsibilities of OSPs. By endorsing the method of the levels of abstract, we first analyse the moral responsibilities (...) of OSPs in the web. These concern the management of online information, which includes information filtering, Internet censorship, the circulation of harmful content, and the implementation and fostering of human rights. We then consider the moral responsibilities ascribed to OSPs on the web and focus on the existing legal regulation of access to users’ data. The overall analysis provides an overview of the current state of the debate and highlights two main results. First, topics related to OSPs’ public role—especially their gatekeeping function, their corporate social responsibilities, and their role in implementing and fostering human rights—have acquired increasing relevance in the specialised literature. Second, there is a lack of an ethical framework that can define OSPs’ responsibilities, and provide the fundamental sharable principles necessary to guide OSPs’ conduct within the multicultural and international context in which they operate. This article contributes to the ethical framework necessary to deal with and by endorsing a LoA enabling the definition of the responsibilities of OSPs with respect to the well-being of the infosphere and of the entities inhabiting it.

In this paper I argue that there is an important anomaly to the causalist/compatibilist paradigm in the philosophy of action and free will. This anomaly, which to my knowledge has gone unnoticed so far, can be found in the philosophy of Harry Frankfurt. Two of his most important contributions to the field – his influential counterexample to the Principle of Alternate Possibilities and his ‘guidance’ view of action – are incompatible. The importance of this inconsistency goes far beyond the issue (...) of coherence within Frankfurt’s philosophy. I shall argue that this inconsistency represents an important anomaly within the causalist/compatibilist framework; so that we should start to seriously consider having to move on from the established paradigm.

This article reviews eight proposed strategies for solving the Symbol Grounding Problem (SGP), which was given its classic formulation in Harnad (1990). After a concise introduction, we provide an analysis of the requirement that must be satisfied by any hypothesis seeking to solve the SGP, the zero semantical commitment condition. We then use it to assess the eight strategies, which are organised into three main approaches: representationalism, semi-representationalism and non-representationalism. The conclusion is that all the strategies are semantically committed and (...) hence that none of them provides a valid solution to the SGP, which remains an open problem. (shrink)

ANDRÉS LOMEÑA: Transhumanism, or human enhancement, suggests the use of new technologies to improve mental and physical abilities, discarding some aspects as stupidity, suffering and so forth. You have been described as technoutopian by critics who write on “Future hypes”. In my opinion, there is something pretty much worse than optimism: radical technopessimism, managed by Paul Virilio, deceased Baudrillard and other thinkers. Why is there a strong strain between the optimistic and pessimistic overview?

This paper argues that there is an urgent need for an international doctrine for cyberspace skirmishes before they escalate into conventional warfare.

The “struggle between liberties and authorities”, as described by Mill, refers to the tension between individual rights and the rules restricting them that are imposed by public authorities exerting their power over civil society. In this paper I argue that contemporary information societies are experiencing a new form of such a struggle, which now involves liberties and authorities in the cyber-sphere and, more specifically, refers to the tension between cyber-security measures and individual liberties. Ethicists, political philosophers and political scientists have (...) long debated how to strike an ethically sound balance between security measures and individual rights. I argue that such a balance can only be reached once individual rights are clearly defined, and that such a definition cannot prescind from an analysis of individual well-being in the information age. Hence, I propose an analysis of individual well-being which rests on the capability approach, and I then identify a set of rights that individuals should claim for themselves. Finally, I consider a criterion for balancing the proposed set of individual rights with cyber-security measures in the information age. (shrink)

The paper provides a selective analysis of the main theories of trust and e-trust (that is, trust in digital environments) provided in the last twenty years, with the goal of preparing the ground for a new philosophical approach to solve the problems facing them. It is divided into two parts. The first part is functional toward the analysis of e-trust: it focuses on trust and its definition and foundation and describes the general background on which the analysis of e-trust rests. (...) The second part focuses on e-trust, its foundation and ethical implications. The paper ends by synthesising the analysis of the two parts. (shrink)

In this article, I analyse deterrence theory and argue that its applicability to cyberspace is limited and that these limits are not trivial. They are the consequence of fundamental differences between deterrence theory and the nature of cyber conflicts and cyberspace. The goals of this analysis are to identify the limits of deterrence theory in cyberspace, clear the ground of inadequate approaches to cyber deterrence, and define the conceptual space for a domain-specific theory of cyber deterrence, still to be developed.

According to the Simple View of intentional action, I have intentionally switched on the light only if I intended to switch on the light. The idea that intending to is necessary for intentionally -ing has been challenged by Bratman (1984, 1987) with a counter-example in which a videogame player is trying to hit either of two targets while knowing that she cannot hit both targets. When a target is hit, the game finishes. And if both targets are about to be (...) hit simultaneously, the game shuts down. The player knows that she cannot hit both targets, but still she concludes that, given her skills, the best strategy is to have a go at each target at the same time. Suppose she hits target 1. It seems obvious that she has hit target 1 intentionally. But, Bratman argues, she could not have intended to hit target 1. Since the scenario is perfectly symmetrical, had the player intended to hit target 1, she would have also had to intend to hit target 2. But the player knows that she cannot hit both targets.

According to the Simple View of intentional action famously refuted by Bratman , φ-ing is intentional only if the agent intended to φ. In this paper I show that none of five different objections to Bratman's counter-example – McCann's , Garcia's , Sverdlik's , Stout's , and Adams's – works. Therefore Bratman's contention that SV is false still stands.

New technologies are often introduced with the purpose of improving our control over a certain task: however, software, AI and robots often cause understandable fears of machines taking control away from us. This is what Ezio Di Nucci calls the ‘control paradox’.

I distinguish between 'hard nudges' and 'soft nudges', arguing that it is possible to show that the latter can be compatible with informed consent - as Cohen has recently suggested; but that the real challenge is the compatibility of the former. Hard nudges are the more effective nudges because they work on less than conscious mechanisms such as those underlying our habits: whether those influences - which are often beyond the subject's awareness - can be reconciled with informed consent in (...) health care is the more challenging question. I suggest two directions for possible answers: on the one hand, looking at the growing empirical literature on mindless judgement and behaviour; and on the other hand considering a more diversified conception of consent, which I sketch.

How does the use of military drones affect the legal, political, and moral responsibility of different actors involved in their deployment and design? This volume offers a fresh contribution to the ethics of drone warfare by providing, for the first time, a systematic interdisciplinary discussion of different responsibility issues raised by military drones. The book discusses four main sets of questions: First, from a legal point of view, we analyse the ways in which the use of drones makes the attribution (...) of criminal responsibility to individuals for war crimes more complicated and what adjustments may be required in international criminal law and in military practices to avoid ’responsibility gaps’ in warfare. From a moral and political perspective, the volume looks at the conditions under which the use of military drones by states is impermissible, permissible, or even obligatory and what the responsibilities of a state in the use of drones towards both its citizens and potential targets are. From a socio-technical perspective, what kind of new human machine interaction might drones bring and which new kinds of shared agency and responsibility? Finally, we ask how the use of drones changes our conception of agency and responsibility. The book will be of interest to scholars and students in ethics and to those in law, politics and the military involved in the design, deployment and evaluation of military drones. (shrink)

Judith Jarvis Thomson has recently proposed a new argument for the thesis that killing the one in the Trolley Problem is not permissible. Her argument relies on the introduction of a new scenario, in which the bystander may also sacrifice herself to save the five. Thomson argues that those not willing to sacrifice themselves if they could may not kill the one to save the five. Bryce Huebner and Marc Hauser have recently put Thomson's argument to empirical test by asking (...) people what they should do in the new trilemma case, in which they may also sacrifice themselves. They found that the majority judge that they should either kill the one or sacrifice themselves; Huebner and Hauser argue that those numbers speak against Thomson's argument. But Thomson's argument was about the dialectical effect of the new trilemma on the traditional dilemma, rather than about the trilemma itself. Here I present the results of a study in which I asked subjects first what they should do in the trilemma and then what they should do in the traditional Trolley Problem. I found that, if asked first about the trilemma, subjects then have the intuition that killing the one in the traditional Bystander at the Switch is not permissible?exactly what Thomson's argument had predicted.

In this article, we focus on the attribution of moral responsibility for the actions of autonomous weapons systems (AWS). To do so, we suggest that the responsibility gap can be closed if human agents can take meaningful moral responsibility for the actions of AWS. This is a moral responsibility attributed to individuals in a justified and fair way and which is accepted by individuals as an assessment of their own moral character. We argue that, given the unpredictability of AWS, meaningful (...) moral responsibly can only be discharged by human agents who are willing to take a moral gambit: they decide to design/develop/deploy AWS despite the uncertainty about the effects an AWS may produce, hoping that unintended and unwanted or unforeseen outcomes may never occurs, but also accepting to be held responsible if such outcomes will occur. We argue that, while a moral gambit is permissible for the use of non-lethal AWS, this is not the case for the actions of lethal autonomous weapon systems. (shrink)

In this report we focus on the definition of autonomous weapons systems (AWS). We provide a comparative analysis of existing official definitions of AWS as provided by States and international organisations, like ICRC and NATO. The analysis highlights that the definitions draw focus on different aspects of AWS and hence lead to different approaches to address the ethical and legal problems of these weapons systems. This approach is detrimental both in terms of fostering an understanding of AWS and in facilitating (...) agreement around conditions of deployment and regulations of their use and, indeed, whether AWS are to be used at all. We draw from the comparative analysis to identify essential aspects of AWS and then offer a definition that provides a value-neutral ground to address the relevant ethical and legal problems. In particular, we identify four key aspects—autonomy; adapting capabilities of AWS; human control; and purpose of use—as the essential factors to define AWS and which are key when considering the related ethical and legal implications.

This article argues that an ethical framework will help to harness the potential of AI while keeping humans in control.

Defence agencies across the globe identify artificial intelligence as a key technology to maintain an edge over adversaries. As a result, efforts to develop or acquire AI capabilities for defence are growing on a global scale. Unfortunately, they remain unmatched by efforts to define ethical frameworks to guide the use of AI in the defence domain. This article provides one such framework. It identifies five principles—justified and overridable uses, just and transparent systems and processes, human moral responsibility, meaningful human control (...) and reliable AI systems—and related recommendations to foster ethically sound uses of AI for national defence purposes.

This commentary aims to place Grace de Laguna’s critique of pragmatism in its historical context. It examines her 1904 response to Henry Heath Bawden, her 1909 attack on John Dewey’s immediate empiricism, and her 1910 book Dogmatism and Evolution, focusing on the following question: Why did she describe her approach as an attempt to complete the pragmatists’ Darwinian revolution in logic?

I analyse an argument according to which medical artificial intelligence represents a threat to patient autonomy—recently put forward by Rosalind McDougall in the Journal of Medical Ethics. The argument takes the case of IBM Watson for Oncology to argue that such technologies risk disregarding the individual values and wishes of patients. I find three problems with this argument: it confuses AI with machine learning; it misses machine learning’s potential for personalised medicine through big data; it fails to distinguish between evidence-based (...) advice and decision-making within healthcare. I conclude that how much and which tasks we should delegate to machine learning and other technologies within healthcare and beyond is indeed a crucial question of our time, but in order to answer it, we must be careful in analysing and properly distinguish between the different systems and different delegated tasks.

This paper articulates the commitments, contours and justifications for a pluralist but non-eclectic critical, realist, reflexive social science with emancipatory aims. In it, we stress that social science can and should be used to guide the conceptualization of desirable and viable forms of social organization and their conditions of realization. In this regard, we advocate explanatory theorizing as an ethical duty of social scientists and as a moral good in itself as well as being an inherent epistemological component of scientific (...) practice. This entails that we take seriously the research strategies apposite to our disciplinary, intertextual and interdiscursive locations to make a serious theoretical case and practical case for the kind of social science here advocated. In our view, such a social science must acknowledge the path-breaking work of Roy Bhaskar, but must also recognize that the arguments deployed in texts as a resource in intellectual work can never be treated as the axiomatic grounds for further thought, but must be interrogated thoroughly and in each case what is to be retained must be defensible. No position has a monopoly of relevant insights and the development of science often involves syntheses. Syntheses must not be syncretic but reflexively interrogated to assess epistemological, ontological and conceptual coherence to avoid eclecticism. Development in critical realist philosophy will, we believe, continue to confront and offer plausible resolutions to a range of battles within and pertinent to philosophy and social-scientific metatheory. However, realists must recognize the continuing importance and discursive effects of a variety of critical and realist work in being able to defend, sustain and develop rigorous social-scientific research with emancipatory commitments.

In this paper, I offer a contribution to the debate on testimony that rests on three elements: the definition of semantic information, the analysis of trust as a second?order property of first?order relations, and Floridi?s Network Theory of Account (NTA). I argue that testimony transmits semantic information and it is neither grounded on trust nor justified by it. Instead, I show that testimony is an occurrence of a first?order relation of communication affected by the second?order property of trust. I then (...) defend the view that an epistemic agent can acquire some knowledge, on the basis of the information communicated through testimony, if and only if the agent is able to connect the transmitted information to the conceptual network of interrelation to which it belongs. I refer to Floridi?s NTA to show how such a network allows the epistemic agent to achieve knowledge on the basis of semantic information. (shrink)

I argue that it is possible for prospective mothers to wrong prospective fathers by bearing their child; and that lifting paternal liability for child support does not correct the wrong inflicted to fathers. It is therefore sometimes wrong for prospective mothers to bear a child, or so I argue here. I show that my argument for considering the legitimate interests of prospective fathers is not a unique exception to an obvious right to procreate. It is, rather, part of a growing (...) consensus that procreation can be morally problematic and that generally talking of rights in this context might not be warranted. Finally, I argue that giving up a right to procreate does not imply nor suggest giving up on women’s absolute right to abort, which I defend. (shrink)

I argue that the empirical literature on priming effects does not warrant nor suggest the conclusion, drawn by prominent psychologists such as J. A. Bargh, that we have no free will or less free will than we might think. I focus on a particular experiment by Bargh – the ‘elderly’ stereotype case in which subjects that have been primed with words that remind them of the stereotype of the elderly walk on average slower out of the experiment’s room than control (...) subjects – and I show that we cannot say that subjects cannot help walking slower or that they are not free in doing do. I then illustrate how these cases can be reconciled and normalized within a Davidsonian theory of action to show that, in walking slower, subjects are acting intentionally. My argument applies across various experiments, including those of goal priming. In the final section I argue that the only cases in which priming effects are efficacious are so-called Buridan cases.

I argue that so-called automatic actions – routine performances that we successfully and effortlessly complete without thinking such as turning a door handle, downshifting to 4th gear, or lighting up a cigarette – pose a challenge to causalism, because they do not appear to be preceded by the psychological states which, according to the causal theory of action, are necessary for intentional action. I argue that causalism cannot prove that agents are simply unaware of the relevant psychological states when they (...) act automatically, because these content-specific psychological states aren’t always necessary to make coherent rational sense of the agent’s behaviour. I then dispute other possible grounds for the attribution of these psychological states, such as agents’ own self-attributions. In the final section I introduce an alternative to causalism, building on Frankfurt’s concept of guidance. (shrink)

I argue against various versions of the ‘attitude’ view of consent and of the ‘action’ view of consent: I show that neither an attitude nor an action is either necessary or sufficient for consent. I then put forward a different view of consent based on the idea that, given a legitimate epistemic context, absence of dissent is sufficient for consent: what is crucial is having access to dissent. In the latter part of the paper I illustrate my view of consent (...) by applying it to the case of consenting to being an organ donor. (shrink)

Determining whether a homoplastic trait is the result of convergence or parallelism is central to many of the most important contemporary discussions in biology and philosophy: the relation between evolution and development, the importance of constraints on variation, and the role of contingency in evolution. In this article, I show that two recent attempts to draw a black-or-white distinction between convergence and parallelism fail, albeit for different reasons. Nevertheless, I argue that we should not be afraid of gray areas: a (...) clarified version of S. J. Gould's earlier account, based on a separation of underlying developmental mechanisms from the realized trait, still represents a useful approach. (shrink)

This article is the second step in our research into the Symbol Grounding Problem (SGP). In a previous work, we defined the main condition that must be satisfied by any strategy in order to provide a valid solution to the SGP, namely the zero semantic commitment condition (Z condition). We then showed that all the main strategies proposed so far fail to satisfy the Z condition, although they provide several important lessons to be followed by any new proposal. Here, we (...) develop a new solution of the SGP. It is called praxical in order to stress the key role played by the interactions between the agents and their environment. It is based on a new theory of meaning—Action-based Semantics (AbS)—and on a new kind of artificial agents, called two-machine artificial agents (AM²). Thanks to their architecture, AM2s implement AbS, and this allows them to ground their symbols semantically and to develop some fairly advanced semantic abilities, including the development of semantically grounded communication and the elaboration of representations, while still respecting the Z condition.
