Self-driving cars hold out the promise of being safer than manually driven cars. Yet they cannot be a 100 % safe. Collisions are sometimes unavoidable. So self-driving cars need to be programmed for how they should respond to scenarios where collisions are highly likely or unavoidable. The accident-scenarios self-driving cars might face have recently been likened to the key examples and dilemmas associated with the trolley problem. In this article, we critically examine this tempting analogy. We identify three important ways (...) in which the ethics of accident-algorithms for self-driving cars and the philosophy of the trolley problem differ from each other. These concern: the basic decision-making situation faced by those who decide how self-driving cars should be programmed to deal with accidents; moral and legal responsibility; and decision-making in the face of risks and uncertainty. In discussing these three areas of disanalogy, we isolate and identify a number of basic issues and complexities that arise within the ethics of the programming of self-driving cars. (shrink)

Chance inevitably plays a role in law but it is not often that we consciously try to import an element of randomness into a legal process. Random Justice: On Lotteries and Legal Decision-Making explores the potential for the use of lotteries in social, and particularly legal, decision-making contexts. Utilizing a variety of disciplines and materials, Neil Duxbury considers in detail the history, advantages, and drawbacks of deciding issues of social significance by lot and argues that the value of the lottery (...) as a legal decision-making device has generally been underestimated. The very fact that there exists widespread resistance to the use of lotteries for legal decision-making purposes betrays a commonly held belief that legal processes are generally more important than are legal outcomes. Where, owing to the existence of indeterminacy, the process of reasoning is likely to be excessively protracted and the reasons provided strongly contestable, the most cost-efficient and impartial decision-making strategy may well be recourse to lot. Aversion to this strategy, while generally understandable, is not necessarily rational. Yet in law, as Professor Duxbury demonstrates, reason is generally valued more highly than is rationality. The lottery is often conceived to be a decision-making device that operates in isolation. Yet lotteries can frequently and profitably be incorporated into other decision-frameworks. The book concludes by controversially considering how lotteries might be so incorporated and also advances the thesis that it may sometimes be sensible to require that adjudication takes place in the shadow of a lottery.

A number of companies including Google and BMW are currently working on the development of autonomous cars. But if fully autonomous cars are going to drive on our roads, it must be decided who is to be held responsible in case of accidents. This involves not only legal questions, but also moral ones. The first question discussed is whether we should try to design the tort liability for car manufacturers in a way that will help along the development and improvement (...) of autonomous vehicles. In particular, Patrick Lin’s concern that any security gain derived from the introduction of autonomous cars would constitute a trade-off in human lives will be addressed. The second question is whether it would be morally permissible to impose liability on the user based on a duty to pay attention to the road and traffic and to intervene when necessary to avoid accidents. Doubts about the moral legitimacy of such a scheme are based on the notion that it is a form of defamation if a person is held to blame for causing the death of another by his inattention if he never had a real chance to intervene. Therefore, the legitimacy of such an approach would depend on the user having an actual chance to do so. The last option discussed in this paper is a system in which a person using an autonomous vehicle has no duty of interfering, but is still held responsible for possible accidents. Two ways of doing so are discussed, but only one is judged morally feasible. (shrink)

Though utilitarianism is far from being universally accepted in the philosophical community, it is taken seriously and treated respectfully. Its critics do not dismiss it out of hand; they do not misrepresent it; they do not belittle or disparage its proponents. They allow the theory to be articulated, developed, and defended from criticism, even if they go on to reject the modified versions. Ethical egoism, a longstanding rival of utilitarianism, is treated very differently. It is said to be “refuted” by (...) arguments of a sort that apply equally well to utilitarianism. It is said to be “unprovable,” when many of the greatest utilitarians themselves, such as Jeremy Bentham (1748–1832), John Stuart Mill (1806–1873), and Henry Sidgwick (1838–1900), admitted that no normative ethical theory, including their own, is provable. Critics of ethical egoism seldom discuss the various theoretical moves that utilitarians are routinely allowed to make, such as (1) fighting the facts, (2) transforming the theory from “act utilitarianism” to “rule utilitarianism,” and (3) biting the bullet. This essay argues that every defensive move made by utilitarians can be made, with equal vigor (if not also plausibility), by ethical egoists. The conclusion is that ethical egoism deserves to be taken more seriously than it is. (shrink)

The article examines whether state officials may shoot down a hijacked airplane which carries uninvolved passengers, if it is known that the plane will be used against the lives of other human beings. In its first sections, it explains the German Federal Constitutional Court’s verdict against such a permission, and it scrutinizes the crucial arguments in this ruling. The author then extends the discussion beyond the path taken by the court. She examines the defensive claims of passengers aboard the plane (...) and the protective claims of potential victims who are present at the hijackers’ target zone. In contrast to the German Federal Constitutional Court, she concludes that state officials must take the claims of both groups of potential victims equally serious, and that such conditions allow applying a consequentialist calculus because it is the only way out of a genuine dilemma.

The recent progress in the development of autonomous cars has seen ethical questions come to the forefront. In particular, life and death decisions regarding the behavior of self-driving cars in trolley dilemma situations are attracting widespread interest in the recent debate. In this essay we want to ask whether we should implement a mandatory ethics setting for the whole of society or, whether every driver should have the choice to select his own personal ethics setting. While the consensus view seems (...) to be that people would not be willing to use an automated car that might sacrifice themselves in a dilemma situation, we will defend the somewhat contra-intuitive claim that this would be nevertheless in their best interest. The reason is, simply put, that a PES regime would most likely result in a prisoner’s dilemma. (shrink)

This paper explores the possibility of moral conflict in Kant’s ethics. An analysis of the only explicit discussion of the topic in his published writings confirms that there is no room for genuine moral dilemmas. Conflict is limited to nonconclusive ‘grounds’ of obligation. They arise only in the sphere of ethical duty and, though defeasible, ought to be construed as the result of valid arguments an agent correctly judges to apply in the situation at hand. While it is difficult to (...) determine in theory what makes some of them stronger than others, these ‘grounds’ can account for practical residue in conflict cases and for a plausible form of agent regret. The principle that ‘ought implies can’ survives intact. (shrink)

‘The several modes of feeling, perception, desire, and will, so far as we are aware of them, are in general called ideas (mental representations) and it may be roughly said that philosophy puts thoughts, categories, or, in more precise language, adequate notions, in the place of generalized images we ordinarily call ideas. Mental impressions such as these may be regarded as the metaphors of thoughts and notions. But to have these figurate conceptions does not imply that we appreciate their intellectual (...) significance, the thoughts and rational notions to which they correspond. Conversely, it is one thing to have thoughts and intelligent notions, and another to know what impressions, perceptions, and feelings correspond to them’.1. (shrink)

Criminal prohibitions typically forbid harming people. Justificatory defenses, such as lesser evil, justifying necessity and justifying self-defense, provide exceptions to such prohibitions if certain conditions are met. One common condition is that the agent is not responsible for the conflict. The questions whether justificatory defenses should include such a condition, and if so what should be its content, are controversial. I argue that responsibility for a conflict counts against protecting the responsible person at the expense of a non-responsible or a (...) less-responsible person, but that this consideration is not necessarily decisive but rather might be outweighed by another consideration, for example, in favor of preventing the more serious harm. I conclude that responsibility for the conditions of justificatory defenses raises a unique question whose proper resolution should be based on the interaction of several general considerations.

Driving light trucks creates the risk of significant harm to other people. Compared to regular cars, light trucks endanger the occupants of other vehicles more and have a markedly more negative impact on the environment. Consequently, many people who currently drive light trucks ought to switch to smaller vehicles.

The defense of necessity, also known as the “choice of evils,” reflects popular moral intuitions and common sense: sometimes, breaking the rules is the right—indeed, the only—thing to do in order to avoid a greater evil. Citing a classic example, mountain climbers may break into a cabin to wait out a deadly snow storm and appropriate the owner’s provisions because their property violations are a lesser evil compared to the loss of life. At the same time, this defense contradicts the (...) fundamental principles of criminal responsibility in that it authorizes violation of rights of innocent bystanders. By allowing the mountain climbers to override the property rights of the cabin owner, the defense effectively forbids the cabin owner to use force in response—a different rule would perpetuate violence. This outcome is at odds with the basic criminal law doctrines. There is no general duty to rescue in Anglo-American law. Yet, by forbidding the cabin owner to use force, the defense of necessity essentially imposes on him the duty to forego his interests in favor of those of the mountain climbers. The paper explores the origins and boundaries of the defense of necessity. It argues that the existing public and private theories of necessity are unsatisfactory and concludes that a viable theory of necessity should be able to explain why it is sometimes permissible to override individual rights of citizens without their consent or fault.
