Interest in just war theory has boomed in recent years, as a revisionist school of thought has challenged the orthodoxy of international law, most famously defended by Michael Walzer [1977]. These revisionist critics have targeted the two central principles governing the conduct of war (jus in bello): combatant equality and noncombatant immunity. The first states that combatants face the same permissions and constraints whether their cause is just or unjust. The second protects noncombatants from intentional attack. In response to these (...) critics, some philosophers have defended aspects of the old orthodoxy on novel grounds. Revisionists counter. As things stand, the prospects for progress are remote. In this paper, we offer a way forward. We argue that exclusive focus on first-order moral principles, such as combatant equality and noncombatant immunity, has led revisionist and orthodox just war theorists to engage in “proxy battles.” Their first-order moral disagreements are at least partly traceable to second-order disagreements about the nature and purpose of political theory. These deeper disputes have been central to the broader discipline of political theory for several years; we hope that bringing them to bear on the ethics of war will help us move beyond the present impasse.

States restrict immigration on a massive scale. Governments fortify their borders with walls and fences, authorize border patrols, imprison migrants in detention centers, and deport large numbers of foreigners. Unjust Borders: Individuals and the Ethics of Immigration argues that immigration restrictions are systematically unjust and examines how individual actors should respond to this injustice. Javier Hidalgo maintains that individuals can rightfully resist immigration restrictions and often have strong moral reasons to subvert these laws. This book makes the case that unauthorized (...) migrants can permissibly evade, deceive, and use defensive force against immigration agents, that smugglers can aid migrants in crossing borders, and that citizens should disobey laws that compel them to harm immigrants. Unjust Borders is a meditation on how individuals should act in the midst of pervasive injustice. (shrink)

After a regime-changing war, a state often engages in lustration—condemnation and punishment of dangerous, corrupt, or culpable remnants of the previous system—e.g., de-Nazification or the more recent de-Ba’athification in Iraq. This common practice poses an important moral dilemma for liberals because even thoughtful and nuanced lustration involves condemning groups of people, instead of treating each case individually. It also raises important questions about collective agency, group treatment, and rectifying historical injustices. Liberals often oppose lustration because it denies moral individualism and (...) ignores rule of law, and their only justifications for lustration are consequentialist ones. This article suggests that lustration may not necessarily be a problem for liberals. While group treatment might be justified on grounds of convenience and pragmatism in times of transitional justice, there are also valid moral arguments consistent with moral individualism and due process for wholesale group punishment after a war. This article offers four overlapping moral justifications, in a robust defense of the core concept of lustration that is covered by each argument. (shrink)

Just institutions have claims on us. There are two reasons for thinking that such claims are warranted. First, one may believe that we are under a natural duty of justice to support and further just institutions. If one believes that it matters whether institutions are just, one also has a reason, almost as a matter of consistency, to support and further just institutions. Second, one may believe that by enjoying the benefits brought about by cooperation through just institutions, one incurs (...) an obligation to support these institutions. Those who accept and enjoy the benefits brought about by cooperation through a just scheme are under an obligation of fairness to reciprocate. But what happens to these reasons to support and comply with an institution if the scheme of cooperation is less than fully just? There is hardly a real-world institution, policy, or scheme of social cooperation that would qualify as fully just. However, questions about obligations of fairness and duties of justice under conditions of injustice have hitherto suffered relative neglect. I shall outline an overall framework for thinking about these questions by asking what the victims of injustice owe to moderately unjust institutions. (shrink)

Yitzhak Benbaji argues that those combatants who have agreed to blindly obey their superiors and who are ordered to fight in unjust wars are released from their duty to deliberate about the merits of the acts that they are ordered to perform. This is because their agreements result in the combatants’ permissible lack of a necessary capacity for moral responsibility. Thus, the combatants are not morally responsible for their wrongful acts—their moral responsibility is “transferred” to their superiors. We argue, first, (...) that Benbaji’s own reasoning suggests that the agreements entered into between the combatants and their superiors are not binding and, second, that even if such agreements are binding, those combatants who obey their orders to fight are nevertheless morally responsible for their wrongful acts. Thus, Benbaji has failed to show that the combatants are permitted to act as ordered. By critically examining Benbaji’s view, then, we defend the revisionist position that just and unjust combatants are morally unequal. (shrink)

Just war theory is currently dominated by two positions. According to the orthodox view, provided that jus in bello principles are respected, combatants have an equal right to fight, regardless of the justice of the cause pursued by their state. According to “revisionists” whenever combatants lack reasons to believe that the war they are ordered to fight is just, their duty is to disobey. I argue that when members of a legitimate state acting in good faith are ordered to fight, (...) they acquire a pro-tanto obligation to obey which does not depend for its validity on the justice of the cause being pursued. However, when the war is unjust, this obligation may be overridden, under certain conditions, by the obligation not to contribute to the unjustified killing of innocents. This is because the pro-tanto force of the duty to obey the law is best understood in terms of “presumptive”, rather than “exclusionary” reasons for action. This approach captures the insights of both the orthodox and the revisionist view, while avoiding the problems that afflict each of them. (shrink)

Just war theory is dominated by two positions. According to the traditional view, combatants both on the just and the unjust side have an equal right to fight, which is not affected by the justice of the cause pursued by their state. According to a recent revisionist account, only combatants fighting for a just cause have such right. David Estlund has offered a sophisticated account that aims to reconcile these two views by looking at our duty to obey the order (...) of democratic political institutions. The article criticizes Estlund’s account and points at an important to be learned from it. (shrink)

A simple argument against Lewisian modal realism as portrayed in On the Plurality of World arises from its treatment of doxastic modalities. It is easily shown that if it is true, it is impossible to doubt the theory on ontological grounds, or, that, if it is possible to maintain doubt about modal realism’s existential postulate, it has to be false. The argument hinges on the fact that modal realism’s main ontological hypothesis, if true, is necessarily true.

Recent work in the ethics of war has done much to challenge the collectivism of the convention-based, Walzerian just war theory. In doing so, it raises the question of when it is permissible for soldiers to resort to force. This article considers this issue and, in doing so, argues that the rejection of collectivism in just war should go further still. More specifically, it defends the ‘Individual-Centric Approach’ to the deep morality of war, which asserts that the justifiability of an (...) individual’s contribution to the war, rather than the justifiability of the war more generally, determines the moral acceptability of their participation. It then goes on to present five implications of the Individual-Centric Approach, including for individual liability to attack in war. (shrink)

Since its earliest incarnations, just war theory has included the requirement that war must be initiated and waged by a legitimate authority. However, while recent years have witnessed a remarkable resurgence in interest in just war theory, the authority criterion is largely absent from contemporary discussions. In this paper I aim to show that this is an oversight worth rectifying, by arguing that the authority criterion plays a much more important role within just war theorising than is commonly supposed. As (...) standardly understood, the authority criterion provides a necessary condition for the justification of the resort to war, but has no bearing on the question of permissible conduct in war. In opposition, I argue for an alternative interpretation of the criterion, which attributes to it a fundamental role in assessing this latter question. With this revised interpretation in place, I then demonstrate its advantages by applying it to the practical issue of armed conflicts that are initiated and fought by non-traditional belligerents. While several theorists have recognised that this common feature of modern armed conflict poses a challenge to mainstream just war theory in general—and to the authority criterion in particular—I argue that existing discussions frequently misconstrue the nature of the challenge, since they assume the standard interpretation of the authority requirement and its role within the theory. I then show that the revised interpretation provides a clearer account of both the challenge posed by non-traditional belligerency and the kind of response that it requires. (shrink)

Conscientious objectors to military service are either general objectors or selective objectors. The former object to all wars; the latter object to only some wars. There is widespread popular and political support in western liberal democracies for exemptions for general objectors, but currently there is little support for exemptions for selective objectors. Many who advocate exemptions for selective objectors attempt to build upon the strength of support that is enjoyed by exemptions for general objectors. They argue that selective objectors ? (...) like general objectors ? sincerely believe that it would be deeply morally wrong for them to fight in the wars to which they object. I argue that a stronger moral case for exemptions for selective objectors relies upon a different claim: selective objections are often accurate. It is often immoral to fight in the wars to which selective objectors object. While some advocates of exemptions for selective objectors have identified accuracy as a reason for offering exemptions, they have usually not adequately distinguished sincerity from accuracy. However, keeping these two moral reasons for exemptions distinct clarifies and strengthens the moral case for exemptions for selective conscientious objectors. (shrink)

Recent controversial cases of killings by police have generated competing Black Lives Matter and Blue Lives Matter movements. Blue Lives Matter proponents claim that the focus on and protests in light of police killings of unarmed black persons is unwarranted. Part of this dispute turns on the moral evaluation of the killing of citizens by law enforcement. To address the dispute, I develop an account of the special moral obligations of law enforcement and show how it can be applied. I (...) argue that members of law enforcement have special moral obligations against killing citizens. The account generates moral guidance for law enforcement in a number of other ways. It implies, finally, that the Blue Lives Matter proponents fundamentally misunderstand the ethics of law enforcement. (shrink)

According to instrumental proceduralism, political power is justified when it is the output of a reliable procedure. In this paper, I examine how procedures are supposed to confer normative properties. Based on this assessment, I conclude that many proceduralists set the reliability bar too low. Next, I motivate two additional requirements for instrumental procedures. I introduce the notion of “predictable” procedural failure and argue that in order for a procedure to confer legitimacy or other normative properties on its output, it (...) must not have failed predictably. Finally, I argue that even when procedures are highly reliable, it must not be the case that their failures fall disproportionately on certain people. The goal is to develop an instrumental proceduralism that is more sensitive to the failures of real institutions. (shrink)

Legitimate political institutions sometimes produce clearly unjust laws. It is widely recognized, especially in the context of war, that agents of the state may not enforce political decisions that are very seriously unjust or are the decisions of illegitimate governments. But may agents of legitimate states enforce unjust, but not massively unjust, laws? In this paper, I respond to three defences of the view that it is permissible to enforce these unjust laws. Analogues of the Walzerian argument from patriotism, the (...) Vitorian epistemic argument, and the proceduralist argument found in Rawls, Estlund, and others do not show that law enforcement is usually permitted to enforce unjust laws. Finally, I develop a proceduralist argument for the thesis that law enforcement is permitted to disregard unjust laws. I conclude by considering objections concerning the problem of optimizing society for justice and the problem of law enforcement agents with deplorable moral beliefs. (shrink)

This paper addresses the relationship between amnesty granted to perpetrators of serious human rights abuses and retributivism. It rebuts arguments advanced by Dan Markel and Lucy Allais in support of their claim that the granting of conditional amnesty—amnesty in exchange for perpetrators’ confessing to, and disclosing the details of, their wrongdoing—by the South African Truth and Reconciliation Commission (TRC) was consistent with retributivism. Markel contends that conditional amnesty was perfectly in line with recipients’ desert, while Allais submits that the TRC (...) secured as much retribution as was possible in the circumstances of South Africa’s democratic transition. The argument of the paper is that while retributivists have good reasons to view conditional amnesty as justified, the reasons provided by Markel and Allais are not among them. (shrink)

Recently in Porter v. McCollum, the United States Supreme Court, citing “a long tradition of according leniency to veterans in recognition of their service,” held that a defense lawyer’s failure to present his client’s military service record as mitigating evidence during his sentencing for two murders amounted to ineffective assistance of counsel. The purpose of this Article is to assess, from the just deserts perspective, the grounds to believe that veterans who commit crimes are to be blamed less by the (...) State than offenders without such backgrounds. Two rationales for a differential treatment of military veterans who commit crimes are typically set forth. The Porter Court raised each, stating that we should treat veterans differently “in recognition of” both “their service” and “the intense stress and mental and emotional toll” of combat. The former factor suggests there being a “social contributions” or gratitude-based discount, whereas the latter factor points towards a “mental disturbance” discount. This Article analyzes the two accounts and raises some doubts about both. This Article then argues that a military veteran who commits a crime should not be blamed to the full extent of his blameworthiness, not necessarily because of his mental capacity nor because of his social contribution, but because the State’s hand in producing his criminality undermines its standing to blame him.

Soldiers sign contracts to obey lawful orders; they also swear oaths to this end. The enlistment contract for the Armed Forces of the United States combines both elements: -/- '9a. My enlistment is more than an employment agreement. As a member of the Armed Forces of the United States, I will be: (1) Required to obey all lawful orders and perform all assigned duties … (4) Required upon order to serve in combat or other hazardous situations.' -/- We standardly think (...) that these oaths and contracts give soldiers new moral reasons to fight. Many also think that soldiers who are ordered to fight by legitimate states have moral reasons to obey those orders, just in virtue of their provenance. -/- We generate these reasons through our voluntary decisions—to sign the contract or swear the oath; to form the institutions and give the orders. They are therefore additional moral reasons, on top of the reasons that we have prior to those voluntary decisions. Simply because they are additional, these reasons seem limited in force and scope. In particular, they arguably cannot override pre-existing commitments. For example, if I already have a duty not to kill an innocent person, my promising to breach that duty seems irrelevant to whether doing so is permissible. Similarly for orders issued by legitimate states: the citizens of a legitimate state have pre-existing moral reasons not to kill the innocent; by what alchemy could their state's orders allow combatants to override those reasons? If additional reasons could make prohibited acts permissible, as Sidgwick observed, ‘we could evade any moral obligation by promising not to fulfil it, which is clearly absurd’ (Sidgwick 1981). -/- We might conclude that the contracts soldiers sign, the oaths they take and the orders they receive have weight only when they pertain to acts that soldiers are already allowed to do. Perhaps these additional reasons can require actions that would otherwise be merely permissible, but they cannot license otherwise prohibited actions. If this is right, then it radically limits the relevance of contracts, oaths and authority to the ethics of war, since almost all conflicts involve soldiers breaching some pre-existing moral duties. -/- This is obviously true for soldiers fighting on the unjust side in a war, since almost all the killing they do is unjust. But in all actual wars soldiers on the just side also kill at least some innocent victims, whether as part of an unjust subordinate aim, as ‘collateral damage’, or simply because their adversaries are not sufficiently responsible for unjustified threats to be liable to be killed. If additional reasons cannot make otherwise prohibited acts permissible, then they are practically irrelevant to the ethics of killing in war, at least in this sense: if fighting is impermissible without regard to the contract, oath and authority of their state, then fighting is simply impermissible. -/- This is a tempting conclusion. In this paper, however, I argue that even if it is true at the level of objective permissibility, it is false for subjective permissibility. And since subjective permissibility is where (at least some of) the action is in the ethics of war, this is a significant result. I explain first why additional reasons can make otherwise subjectively prohibited acts permissible, then why just war theorists should care more than they seem to about subjective permissibility. Although I focus throughout on the ethics of war, my arguments generalise to all kinds of additional reasons. (shrink)

Many political theorists argue that immigration restrictions are unjust and defend broadly open borders. In this paper, I examine the implications of this view for individual conduct. In particular, I argue that the citizens of states that enforce unjust immigration restrictions have duties to disobey certain immigration laws. States conscript their citizens to help enforce immigration law by imposing legal duties on these citizens to monitor, report, and refrain from interacting with unauthorized migrants. If an ideal of open borders is (...) true, these laws are unjust. Furthermore, if citizens comply with their legal duties, they contribute to violating the rights of migrants. We are obligated to refrain from contributing to rights-violations. So, citizens are obligated to disobey immigration laws. I defend the moral requirement to disobey immigration laws against the objection that disobedience to the law is excessively risky and the objection that citizens have political obligations to obey the law.

The conventional view of Just War thinking holds that militaries operate under “special” moral rules in war. Conventional Just War thinking establishes a principled approach to such moral exceptionalism in order to prevent arbitrary or capricious uses of military force. It relies on the notion that soldiers are instruments of the state, which is a view that has been critiqued by the Revisionist movement. The Revisionist critique rightly puts greater emphasis on the moral agency of individual soldiers: they are not (...) mere instruments of the state. Although Revisionism has something particularly important to contribute when applied to cases that are short-of-war, where an individual agent’s moral culpability plays a greater role, soldiers fighting wars are not wholly autonomous moral agents. An Institutionalist approach that responds to Revisionist criticisms is a plausible alternative to the conventional Just War account for grounding the moral exceptionalism of war. For the Institutionalist, soldiers are moral agents with state-imposed obligations whose fundamental responsibility is the performance of the proper moral ends of the military institution they serve. If this is true, then soldiers have a moral obligation to be attentive to the moral corruption of the military institution of which they are a part. (shrink)

Treason is one of the most serious legal offences that there are, in most if not all jurisdictions. Laws against treason are rooted in deep-seated moral revulsion about acts which, in the political realm, are paradigmatic examples of breaches of loyalty. Yet, it is not altogether clear what treason consists in: someone’s traitor is often another’s loyalist. In this paper, my aim is twofold: to offer a plausible conceptual account of treason, and to partly rehabilitate traitors. I focus on informational (...) treason, as the act of passing secret intelligence to foreign actors without authorization. I argue that informational treason is sometimes justified, indeed morally mandatory; even when it is morally wrong, its beneficiaries are sometimes justified, indeed obliged, to make use of the intelligence thereby provided.

In his recent book Killing in War, McMahan develops a powerful argument for the view that soldiers on opposite sides of a conflict are not morally on a par once the war has started: whether they have the right to kill depends on the justness of their war. In line with just war theory in general, McMahan scrutinizes the ethics of killing the enemy. In this article, I accept McMahan's account, but bring it to bear on the entirely neglected, but (...) nevertheless interesting, issue of what the military call killings or, as I refer to such acts here, internecine war killings. I focus on the case of the soldier who is ordered by his officer, at gunpoint, to go into action or to kill innocent civilians, and who kills his officer in self-defence. I argue that, at the bar of McMahan's account of the right to kill in self-defence, the officer lacks a justification for attacking the soldier as a means of enforcing his order, and the soldier thus sometimes (but not always) has the right to kill his officer should the latter so act.

This paper makes the case for the permissibility of post-conflict amnesties, although not on prudential grounds. It argues that amnesties of a certain scope, targeted to certain categories of perpetrators, and offered in certain contexts are morally permissible because they are an acknowledgment of the difficulty of attributing criminal responsibility in mass violence contexts. Based on this idea, the paper develops the further claim that deciding which amnesties are permissible and which ones are not should be decided on a case-by-case (...) basis. Against what seems to be an increasingly popular assumption of some international actors, just as "blanket" amnesties are impermissible, so is an absolutist rejection of all types of amnesties.

:This essay argues for what may be called the parity thesis: Whenever it would be morally permissible to kill a civilian in self-defense or in defense of others against that civilian's unjust acts, it would also be permissible to kill government officials, including police officers, prison officers, generals, lawmakers, and even chief executives. I argue that in realistic circumstances, violent resistance to state injustice is permissible, even and perhaps especially in reasonably just democratic regimes. When civilians see officials about to (...) commit certain severe injustices — such as police officers engaging in excessive violence — they may sometimes act unilaterally and kill the offending officials. I consider and rebut a wide range of objections, including objections against vigilantism, objections based on state legitimacy, and objections that violence can produce bad fallout.

It is commonly stated, by both whistleblower protection laws and political philosophers, that a breach of state secrecy by disclosing classified documents is justified if it serves the public interest. The problem with this defense of justified whistleblowing, however, is that the operative term – the public interest – is all too often left unclarified. This is problematic, because it leaves potential whistleblowers without sufficient certainty that their disclosures will be covered by the defense, leading many to err on the (...) side of caution and remain silent, depriving the public of much-needed information. Failing an agreed upon definition of the public interest or a process to determine it, judges’ applications of the public interest in whistleblowing cases have been criticized for demonstrating ‘judicial idiosyncrasy’. The present paper, therefore, sets out to provide some clarity concerning the concept of the public interest, and to ascertain the extent to which a public interest defense for whistleblowing is feasible and desirable.

Revisionist just war theorists maintain that, soldiers, and not merely their leaders or superiors, bear moral responsibility for objectively wrongful harms imposed in pursuit of an unjust war. The conviction that underlies revisionism is that a person's responsibility for her intentional, objectively unjustified, killing is non-transferable. In this essay I aim to elaborate a specific counterexample to this general claim. I will argue that in cases that I characterize as "special authority cases", the moral responsibility for the unintended outcomes that (...) a person brings about because of following the orders of a legitimate authority is transferred to the authority.

The purpose of this paper is to show that conscientious objection to military service is essentially not a dilemma of freedom of conscience versus the duty to obey the law, but above all a dilemma between two conflicting patriotic moral obligations. Furthermore, the paper demonstrates that CO is justifiable on the basis of what is known as moderate patriotism, that is, out of a patriotism which is committed simultaneously to universal and particular values. The paper begins with a critical discussion (...) of theoretical weaknesses in liberal thought of CO. Then, the concept of moderate patriotism is presented, followed by a discussion of the notion of patriotic CO. The next stage presents a step Towards A Theory of PCO to Military Service and shows how it differs from other liberal theories of disobedience. The conclusion is that if CO on patriotic grounds is morally justifiable, it follows that this is an act committed within the framework of legitimate political discourse. Therefore, PCO is politically legitimate even if it is not always legal. In other words, the discussion of PCO offers a theoretical distinction between politicallegitimacy and legality. (shrink)

War should be understood as an actual, intentional and widespread armed conflict between political communities. Thus, fisticuffs between individual persons do not count as a war, nor does a gang fight, nor does a feud on the order of the Hatfields versus the McCoys. War is a phenomenon which occurs only between political communities, defined as those entities which either are states or intend to become states (in order to allow for civil war). Classical war is international war, a war (...) between different states, like the two World Wars. But just as frequent is war within a state between rival groups or communities, like the American Civil War. Certain political pressure groups, like terrorist organizations, might also be considered “political communities,” in that they are associations of people with a political purpose and, indeed, many of them aspire to statehood or to influence the development of statehood in certain lands.

Contemporary just war theory is divided into two broad camps: revisionists and traditionalists. Traditionalists seek to provide moral foundations for something close to current international law, and in particular the laws of armed conflict. Although they propose improvements, they do so cautiously. Revisionists argue that international law is at best a pragmatic fiction—it lacks deeper moral foundations. In this article, I present the contemporary history of analytical just war theory, from the origins of contemporary traditionalist just war theory in Michael (...) Walzer's work to the revisionist critique of Walzer and the subsequent revival of traditionalism. I discuss central questions of methodology, as well as consider the morality of resorting to war and the morality of conduct in war. I show that although the revisionists exposed philosophical shortcomings in Walzer's arguments, their radical conclusions should prompt us not to reject the broad contemporary consensus, but instead to seek better arguments to underpin it.

I shall argue that in some wars both sides are (as a collective) justified, that is, they can both satisfy valid jus ad bellum requirements. Moreover, in some wars – but not in all – the individual soldiers on the unjustified side (that is, on the side without jus ad bellum) may nevertheless kill soldiers (and also civilians as a side-effect) on the justified side, even if the enemy soldiers always abide by jus in bello constraints. Traditional just war theory (...) and self-proclaimed “revisionist” just war theory think otherwise since the former focuses on the law enforcement or public authority justification for inflicting harm and the latter on the self-defense justification. These are both intrinsically asymmetrical justifications: there is no justified self-defense (properly understood) against justified self-defense, nor is there justified law-enforcement against justified law-enforcement. However, there can, as I will show, be justified self-defense against force that is justified by a necessity justification, and there can be force justified by a necessity justification being used against force that is also justified by a necessity justification. The necessity justification is not intrinsically asymmetrical, and it is an indispensable justification in the context of war. Moreover, with regard to some forms of inflicting harm on others one may give special weight to one’s own interests and the interests of those to whom one has special responsibilities when assessing the proportionality of those acts. That is, the proportionality calculation may be agent-relative. This is in particular so in the case of foreseeably preventing innocent and non-threatening people from being saved (for instance, by shooting down a tactical bomber who would have saved them by destroying an ammunitions factory) but less so in the case of the intentional or foreseeable direct harming of innocent and non-threatening people (dropping bombs on people standing near an ammunitions factory). In the light of these considerations, I will then answer the question as to when soldiers may justifiably participate in war (and when not). (shrink)
