In 1969, John McCarthy and Pat Hayes uncovered a problem that has haunted the field of artificial intelligence ever since--the frame problem. The problem arises when logic is used to describe the effects of actions and events. Put simply, it is the problem of representing what remains unchanged as a result of an action or event. Many researchers in artificial intelligence believe that its solution is vital to the realization of the field's goals. Solving the Frame Problem presents the various (...) approaches to the frame problem that have been proposed over the years. The author presents the material chronologically--as an unfolding story rather than as a body of theory to be learned by rote. There are lessons to be learned even from the dead ends researchers have pursued, for they deepen our understanding of the issues surrounding the frame problem. In the book's concluding chapters, the author offers his own work on event calculus, which he claims comes very close to a complete solution to the frame problem. Artificial Intelligence series.

Will future lethal autonomous weapon systems (LAWS), or ‘killer robots’, be a threat to humanity? The European Parliament has called for a moratorium or ban of LAWS; the ‘Contracting Parties to the Geneva Convention at the United Nations’ are presently discussing such a ban, which is supported by the great majority of writers and campaigners on the issue. However, the main arguments in favour of a ban are unsound. LAWS do not support extrajudicial killings, they do not take responsibility (...) away from humans; in fact they increase the abil-ity to hold humans accountable for war crimes. Using LAWS in war would probably reduce human suffering overall. Finally, the availability of LAWS would probably not increase the probability of war or other lethal conflict—especially as compared to extant remote-controlled weapons. The widespread fear of killer robots is unfounded: They are probably good news. (shrink)

We propose that virtue ethics can be used to address ethical issues central to discussions about sex robots. In particular, we argue virtue ethics is well equipped to focus on the implications of sex robots for human moral character. Our evaluation develops in four steps. First, we present virtue ethics as a suitable framework for the evaluation of human–robot relationships. Second, we show the advantages of our virtue ethical account of sex robots by comparing it to current (...) instrumentalist approaches, showing how the former better captures the reciprocal interaction between robots and their users. Third, we examine how a virtue ethical analysis of intimate human–robot relationships could inspire the design of robots that support the cultivation of virtues. We suggest that a sex robot which is equipped with a consent-module could support the cultivation of compassion when used in supervised, therapeutic scenarios. Fourth, we discuss the ethical implications of our analysis for user autonomy and responsibility. (shrink)

Some critics of sex-robots worry that their use might spread objectifying attitudes about sex, and common sense places a higher value on sex within love-relationships than on casual sex. If there could be mutual love between humans and sex-robots, this could help to ease the worries about objectifying attitudes. And mutual love between humans and sex-robots, if possible, could also help to make this sex more valuable. But is mutual love between humans and robots possible, or (...) even conceivable? We discuss three clusters of ideas and associations commonly discussed within the philosophy of love, and relate these to the topic of whether mutual love could be achieved between humans and sex-robots: (i) the idea of love as a “good match”; (ii) the idea of valuing each other in our distinctive particularity; and (iii) the idea of a steadfast commitment. We consider relations among these ideas and the sort of agency and free will that we attribute to human romantic partners. Our conclusion is that mutual love between humans and advanced sex-robots is not an altogether impossible proposition. However, it is unlikely that we will be able to create robots sophisticated enough to be able to participate in love-relationships anytime soon. -/- . (shrink)

Can we trust robots? Responding to the literature on trust and e-trust, this paper asks if the question of trust is applicable to robots, discusses different approaches to trust, and analyses some preconditions for trust. In the course of the paper a phenomenological-social approach to trust is articulated, which provides a way of thinking about trust that puts less emphasis on individual choice and control than the contractarian-individualist approach. In addition, the argument is made that while robots (...) are neither human nor mere tools, we have sufficient functional, agency-based, appearance-based, social-relational, and existential criteria left to evaluate trust in robots. It is also argued that such evaluations must be sensitive to cultural differences, which impact on how we interpret the criteria and how we think of trust in robots. Finally, it is suggested that when it comes to shaping conditions under which humans can trust robots, fine-tuning human expectations and robotic appearances is advisable. (shrink)

Calls that pair ethical and conscious AI with ethical and conscious robots may feel natural. Many contemporary robots use machine learning, and many AI systems are described in agentive terms. Yet the pairing can hide a conceptual shortcut. It quietly suggests that AI ethics and robot ethics are the same moral question applied to different shells. My claim in this opinion piece is modest but consequential: treating robotics and AI as a single moral category encourages avoidable category mistakes (...) about where moral agency sits, where harms arise, how responsibility is attributed, and what consciousness claims could plausibly mean in deployed systems.

This paper explores a line of concern underrepresented in the emerging debate about sex robots, arguing for caution in their development. Today’s sex robots cannot suffer because they lack sentience. However, future sex robots that may be sentient could suffer harm due to precedents set today regarding behaviors toward their non-sentient predecessors. The challenge emerges from our lack of philosophically uncontested criteria for sentience in a robot. This paper discusses the phenomenon of spillover, described by Robert Nozick (...) as a situation in which members of one moral category are treated in ways appropriate to another. In the case of sex robots, spillover occurs when robots that could be sentient are treated in ways appropriate to robots that are certainly not sentient. Sex robots could cause harmful spillover.

Can robots have significant moral status? This is an emerging topic of debate among roboticists and ethicists. This paper makes three contributions to this debate. First, it presents a theory – ‘ethical behaviourism’ – which holds that robots can have significant moral status if they are roughly performatively equivalent to other entities that have significant moral status. This theory is then defended from seven objections. Second, taking this theoretical position onboard, it is argued that the performative threshold that (...) robots need to cross in order to be afforded significant moral status may not be that high and that they may soon cross it (if they haven’t done so already). Finally, the implications of this for our procreative duties to robots are considered, and it is argued that we may need to take seriously a duty of ‘procreative beneficence’ towards robots.

This paper tries to understand the phenomenon that humans are able to empathize with robots and the intuition that there might be something wrong with “abusing” robots by discussing the question regarding the moral standing of robots. After a review of some relevant work in empirical psychology and a discussion of the ethics of empathizing with robots, a philosophical argument concerning the moral standing of robots is made that questions distant and uncritical moral reasoning about (...) entities’ properties and that recommends first trying to understand the issue by means of philosophical and artistic work that shows how ethics is always relational and historical, and that highlights the importance of language and appearance in moral reasoning and moral psychology. It is concluded that attention to relationality and to verbal and non-verbal languages of suffering is key to understand the phenomenon under investigation, and that in robot ethics we need less certainty and more caution and patience when it comes to thinking about moral standing.

In July 2014, the roboticist Ronald Arkin suggested that child sex robots could be used to treat those with paedophilic predilections in the same way that methadone is used to treat heroin addicts. Taking this onboard, it would seem that there is reason to experiment with the regulation of this technology. But most people seem to disagree with this idea, with legal authorities in both the UK and US taking steps to outlaw such devices. In this paper, I subject (...) these different regulatory attitudes to critical scrutiny. In doing so, I make three main contributions to the debate. First, I present a framework for thinking about the regulatory options that we confront when dealing with child sex robots. Second, I argue that there is a prima facie case for restrictive regulation, but that this is contingent on whether Arkin’s hypothesis has a reasonable prospect of being successfully tested. Third, I argue that Arkin’s hypothesis probably does not have a reasonable prospect of being successfully tested. Consequently, we should proceed with utmost caution when it comes to this technology.

While robots were traditionally built to achieve economic efficiency and financial profits, their roles are likely to change in the future with the aim to provide social support and companionship. In this research, we examined whether the robot’s proposed function (social vs. economic) impacts judgments of mind and moral treatment. Studies 1a and 1b demonstrated that robots with social function were perceived to possess greater ability for emotional experience, but not cognition, compared to those with economic function and (...) whose function was not mentioned explicitly. Study 2 replicated this finding and further showed that low economic value reduced ascriptions of cognitive capacity, whereas high social value resulted in increased emotion perception. In Study 3, robots with high social value were more likely to be afforded protection from harm, and such effect was related to levels of ascribed emotional experience. Together, the findings demonstrate a dissociation between function type (social vs. economic) and ascribed mind (emotion vs. cognition). In addition, the two types of functions exert asymmetric influences on the moral treatment of robots. Theoretical and practical implications for the field of social psychology and human-computer interaction are discussed. (shrink)

Children ranging from 3 to 5 years were introduced to two anthropomorphic robots that provided them with information about unfamiliar animals. Children treated the robots as interlocutors. They supplied information to the robots and retained what the robots told them. Children also treated the robots as informants from whom they could seek information. Consistent with studies of children's early sensitivity to an interlocutor's non-verbal signals, children were especially attentive and receptive to whichever robot displayed the (...) greater non-verbal contingency. Such selective information seeking is consistent with recent findings showing that although young children learn from others, they are selective with respect to the informants that they question or endorse.
