The underlying thesis of the research in ethical autonomy for lethal autonomous unmanned systems is that they will potentially be capable of performing more ethically on the battlefield than are human soldiers. In this article this hypothesis is supported by ongoing and foreseen technological advances and perhaps equally important by an assessment of the fundamental ability of human warfighters in today's battlespace. If this goal of better-than-human performance is achieved, even if still imperfect, it can result in a reduction in (...) noncombatant casualties and property damage consistent with adherence to the Laws of War as prescribed in international treaties and conventions, and is thus worth pursuing vigorously.

Jeff McMahan urges us to reject the view, dominant throughout history, that mere participation in an unjust war is not wrong.

The United States Army’s Future Combat Systems Project, which aims to manufacture a “robot army” to be ready for deployment by 2012, is only the latest and most dramatic example of military interest in the use of artificially intelligent systems in modern warfare. This paper considers the ethics of a decision to send artificially intelligent robots into war, by asking who we should hold responsible when an autonomous weapon system is involved in an atrocity of the sort that would normally (...) be described as a war crime. A number of possible loci of responsibility for robot war crimes are canvassed; the persons who designed or programmed the system, the commanding officer who ordered its use, the machine itself. I argue that in fact none of these are ultimately satisfactory. Yet it is a necessary condition for fighting a just war, under the principle of jus in bellum, that someone can be justly held responsible for deaths that occur in the course of the war. As this condition cannot be met in relation to deaths caused by an autonomous weapon system it would therefore be unethical to deploy such systems in warfare. (shrink)

From the apathetic reaction to atrocities committed in Vietnam by the United States and its allies, one may conclude that moral restrictions on the conduct of war command almost as little sympathy among the general public as they do among those charged with the formation of U.S. military policy. Even when restrictions on the conduct of warfare are defended, it is usually on legal grounds alone: their moral basis is often poorly understood. I wish to argue that certain restrictions are (...) neither arbitrary nor merely conventional, and that their validity does not depend simply on their usefulness. There is, in other words, a moral basis for the rules of war, even though the conventions now officially in force are far from giving it perfect expression. (shrink)

abstract Much of the literature on torture in recent years takes the position of denouncing the barbarity of torture, while allowing for exceptions to this veto in extreme circumstances. The ticking‐bomb argument, where a terrorist is tortured in order to extract information of a primed bomb located in a civilian area, is often invoked as one of those extreme circumstances where torture becomes justified. As the War on Terrorism intensifies, the ticking‐bomb argument has become the dominant line of reasoning used (...) by both academics and policy advisers to justify a legalized, state‐sponsored program of torture. This paper argues for the unconditional refutation of any attempt to justify torture, without exceptions. We argue against the consequentialist reasoning of the ticking‐bomb argument not from a deontological position, but on consequentialist grounds. Empirical evidence suggests that the institutionalization of torture practices creates serious problems. Torture interrogation fails to fulfil its initial purpose as a low‐cost life saver, while its long‐term potential is the devastation of democratic institutions. (shrink)

That the successful development of fully autonomous artificial moral agents (AMAs) is imminent is becoming the received view within artificial intelligence research and robotics. The discipline of Machines Ethics, whose mandate is to create such ethical robots, is consequently gaining momentum. Although it is often asked whether a given moral framework can be implemented into machines, it is never asked whether it should be. This paper articulates a pressing challenge for Machine Ethics: To identify an ethical framework that is both (...) implementable into machines and whose tenets permit the creation of such AMAs in the first place. Without consistency between ethics and engineering, the resulting AMAs would not be genuine ethical robots, and hence the discipline of Machine Ethics would be a failure in this regard. Here this challenge is articulated through a critical analysis of the development of Kantian AMAs, as one of the leading contenders for being the ethic that can be implemented into machines. In the end, however, the development of Kantian artificial moral machines is found to be anti-Kantian. The upshot of all this is that machine ethicists need to look elsewhere for an ethic to implement into their machines. (shrink)

Duane Cady views warism and pacifism as polar extremes on a continuum that embraces a full spectrum of ethical positions on the morality of war and peace. Realizing that he could not intellectually defend the notions of just-war theory, he found that he was a reluctant pacifist. In this new edition of From Warism to Pacifism, Cady continues to expose the pervasive, subconscious warism that is the dominant ideology in modern Western culture. He explores the changes over the last twenty (...) years—from the end of the Cold War to the ongoing “war on terror,” as well as Barack Obama winning the Nobel Prize for Peace. Like racism and sexism, the uncritical presumption that war is morally justifiable, even morally required, misguides our attitudes and institutions. In its place, Cady proposes the development of a positive concept of peace. Citing common objections to pacifist values, he describes peace as something more than the mere absence of war and demonstrates that pacifism is a defensible position. (shrink)

The emerging discipline of Machine Ethics is concerned with creating autonomous artificial moral agents that perform ethically significant actions out in the world. Recently, Wallach and Allen (Moral machines: teaching robots right from wrong, Oxford University Press, Oxford, 2009) and others have argued that a virtue-based moral framework is a promising tool for meeting this end. However, even if we could program autonomous machines to follow a virtue-based moral framework, there are certain pressing ethical issues that need to be taken (...) into account, prior to the implementation and development stages. Here I examine whether the creation of virtuous autonomous machines is morally permitted by the central tenets of virtue ethics. It is argued that the creation of such machines violates certain tenets of virtue ethics, and hence that the creation and use of those machines is impermissible. One upshot of this is that, although virtue ethics may have a role to play in certain near-term Machine Ethics projects (e.g. designing systems that are sensitive to ethical considerations), machine ethicists need to look elsewhere for a moral framework to implement into their autonomous artificial moral agents, Wallach and Allen’s claims notwithstanding.

Telerobotically operated and semiautonomous machines have become a major component in the arsenals of industrial nations around the world. By the year 2015 the United States military plans to have one-third of their combat aircraft and ground vehicles robotically controlled. Although there are many reasons for the use of robots on the battlefield, perhaps one of the most interesting assertions are that these machines, if properly designed and used, will result in a more just and ethical implementation of warfare. This (...) paper will focus on these claims by looking at what has been discovered about the capability of humans to behave ethically on the battlefield, and then comparing those findings with the claims made by robotics researchers that their machines are able to behave more ethically on the battlefield than human soldiers. Throughout the paper we will explore the philosophical critique of this claim and also look at how the robots of today are impacting our ability to fight wars in a just manner. (shrink)

The title of this paper is misleading. I do not intend to defend pacifism against those who would contend that it is false. In point of fact, I agree that pacifism is false, and profoundly so, if any moral belief is. Yet pacifism’s critics sometimes believe it is false for inadequate reasons, and it is important to make the inadequacy of these reasons apparent whenever possible. Otherwise pacifism’s apologists are apt to suppose that they have overcome their critic’s strongest objections, (...) when, in fact, in exposing the inadequacy of the grounds of certain objections, they have succeeded only in meeting the weaker ones. What I intend to defend, then, is not the truth of pacifism, but the very different claim that pacifism is not necessarily false. This objection to pacifism, which, if sound, would silence the debate over its possible merits, and which, therefore, if sound, would be a strong objection indeed, is set forth by Jan Narveson in his paper on pacifism. I hope to show that this objection is unfounded, and I shall, accordingly, direct my argument principally against Narveson’s. And yet it is with a certain degree of reluctance that I do so, since Narveson, himself, suggests that “most people” whose opinion he has solicited would agree with me that pacifism, although false, is not necessarily so. One runs a risk, in such a situation, of pouring old wine into new bottles. (shrink)
