What Is Pacifism? Its History and Hardest Questions

Short answer

Pacifism is a broad family of moral, philosophical, religious, and political positions united by a deep objection to war and violence. Some pacifists believe that intentionally taking a life is never permissible. Others allow for exceptions but argue that actual wars rarely meet the conditions that could justify them. Many object not to resistance itself, but to methods of resistance that depend on killing and destroying an adversary. Pacifism, then, does not necessarily mean passivity, surrender, or abandoning people who need protection. Its hardest questions arise when an innocent person faces immediate violence and nonviolent means of protection may not be enough. ^[1]

“Pacifist” is a word spoken both with respect and with contempt. To some, it describes someone who refuses to take part in war. To others, it describes someone who may leave a victim of aggression undefended. There is a considerable distance between these two portraits. Neither declarations of moral purity nor jokes about “naive idealism” can bridge it. We first need to ask what pacifists themselves consider impermissible, what they propose instead, and where the limits of their convictions lie.

The value of pacifism is not that it hands us a ready-made rule for every situation. It asks institutions—and each of us—an uncomfortable question: if human life matters so much, why is it so easy to persuade us that destroying it becomes morally straightforward when the uniform, flag, or political objective changes? But there is an equally uncomfortable question in the other direction: if we refuse to harm an aggressor, what obligations do we still have to those in need of protection?

Understanding pacifism means refusing to lose either question. We must not turn the defence of human beings into a worship of force, or turn the refusal to kill into a refusal to take responsibility. This essay examines not a single doctrine but an argument that has lasted for centuries, taking on new forms with every war, social movement, and new means of destruction.

1. Where the word came from—and what it means

The word is much younger than many of the ideas it names. The French term pacifisme gained currency in the international peace movement around the turn of the twentieth century. In 1901, the French lawyer Émile Arnaud proposed it as a shared name for the peace movement, writing about it in August before the Universal Peace Congress met in Glasgow that September. At first, it referred primarily to a public programme: arbitration instead of war, international law, disarmament, and institutions for the peaceful settlement of disputes. Those advocates of peace did not always regard every use of defensive force as categorically wrong. After the catastrophe of the First World War, the term became more closely associated in some countries with an individual's absolute refusal to participate in war. The change in language reflected a change in historical experience. ^[2]

There is no universally accepted definition of pacifism. In the Stanford Encyclopedia of Philosophy, Andrew Fiala examines a spectrum of positions, ranging from an almost unconditional rejection of violence to opposition to war as a social institution. These differences are not simply a problem of vocabulary. People have come to reject war for different reasons, and they draw the boundary of permissible action in different places. ^[1]

Four terms need particular care. Pacifism is primarily a position concerning the moral permissibility of war and violence. Nonviolence is both an ethical principle and a range of methods of action: negotiation, boycotts, strikes, civil disobedience, noncooperation, and assistance to people under threat. Nonresistance to evil by violence is a more specific moral commitment that may reject even coercive intervention; Leo Tolstoy developed it with unusual depth in Russian thought. An anti-war position, by contrast, may mean opposing a particular war without rejecting war in principle.

A person can therefore use nonviolent methods without being a pacifist—for example, choosing a strike because it is more effective than an armed uprising. Conversely, someone deeply opposed to war may never join a public campaign or offer a comprehensive strategy of civil resistance. Antimilitarists may criticize the military's influence on politics while accepting armed self-defence. Conscientious objectors may be concerned above all with their personal inability, on grounds of conscience, to participate in killing. When these positions are treated as interchangeable, the discussion quickly becomes confused.

The historian Martin Ceadel distinguishes pacifism, a principled rejection of taking part in or supporting war, from pacificism, a reformist effort to prevent and eventually abolish war that still allows for defensive force in exceptional circumstances. Pacifists may advocate political reforms, and pacificists may act from deeply personal convictions: this is not simply a contrast between private conscience and public policy. Ceadel borrowed the term pacificism in this sense from A. J. P. Taylor, who used it in 1957. The terminology has not become universal, and many writers still use “pacifism” more broadly. The important distinction is whether war admits any moral exception. ^[2]

2. How many forms of pacifism are there?

The usual starting point is the contrast between absolute and conditional pacifism. The absolute position holds that war, intentional killing, or certain kinds of violence are impermissible in every circumstance. Its strength lies in a clear moral boundary that cannot simply be moved by promises of a better future. Its difficulty becomes apparent in exceptional cases: if seriously harming an attacker is the only way to stop the imminent killing of an innocent person, does the prohibition remain absolute?

Conditional pacifism offers a more qualified answer. Its advocates accept that defensive force may be morally justified in some circumstances, yet regard many actual wars as unacceptable because of indiscriminate harm, disproportionality, unreliable information, and possible alternatives. Some oppose a particular war; others reject almost the entire contemporary practice of warfare without rejecting the very idea of defence. The distinction matters. In the first case, the moral assessment can change with the circumstances. In the second, the ways states currently wage war are themselves under scrutiny. ^[1]

Pacifists also disagree about the foundations of their convictions. Some begin with duties: there are actions a person must not commit, whatever good consequences might follow. Philosophers call this a deontological approach. Others assess outcomes, arguing that wars generally inflict more harm than they prevent. This is a consequentialist approach. The former encounters a conflict of duties when the prohibition on harming someone clashes with the duty to protect another person. The latter must confront the evidence: if a limited use of force really does prevent greater harm, an argument based on consequences no longer yields an unconditional ban.

There is a further distinction between minimal and more expansive versions. For some pacifists, interstate war is the principal object of objection. Others oppose capital punishment, torture, cruelty to animals, or the intentional harming of sentient beings more generally. This broader view has affinities with certain interpretations of ahimsa, but it is not part of the necessary definition of pacifism. Pacifists can hold different views about food, policing, criminal punishment, and self-defence.

Finally, pacifism may be personal or universal in scope. Someone may see refusing to carry weapons as their own vocation without demanding the same of others. Someone else may insist that the moral prohibition applies equally to everyone. The first position raises a question: is it fair to benefit from security maintained by people willing to use force? The second raises another: who has the authority to demand that a victim of aggression refrain from resisting? Different answers do not erase the shared objection to war. They show why a single label cannot settle the argument.

3. A history older than its name

It would be tempting to draw an elegant straight line from ancient India through Christianity to Tolstoy, Gandhi, and King. But that would reduce distinct traditions to steps on a staircase built in advance. Their aims were not the same. Some sought liberation from karmic bondage; others fidelity to a religious commandment; others a new international order; still others freedom from colonial rule and equal civil rights. Similar methods do not make all these movements one school of thought.

In Jainism, ahimsa—refraining from harm to living beings—is central to ethical and spiritual discipline. Monastic vows are stricter than the everyday expectations placed on lay followers, and concern for even the smallest living creatures is not a metaphor but a practical moral obligation. The rejection of killing is also important across Buddhist traditions, yet Buddhism's historical and philosophical diversity makes it inaccurate to describe all Buddhists as unconditional pacifists. The Bhagavad Gita itself grapples with a warrior's duty; later nonviolent readings of the text remain interpretations, not the only possible reading. Ahimsa can be called an ancient relative of modern political pacifism only if these differences are kept in view. ^[3]

Early Christianity contained powerful teachings against revenge, killing, and military service. The Sermon on the Mount became one of the most important texts for later advocates of nonresistance. But the first Christian centuries were more complex than the claim that “the entire early Church was pacifist.” Practices differed across communities; Christians who served as soldiers are historically attested; and objections to military service could concern imperial worship as well as killing. In later centuries, a Christian theory of war permissible under restrictive conditions developed. Christian history is not simply a steady retreat from a single original rule. It is a long dispute over power, conscience, service, and violence. ^[4]

Quakers, Mennonites, the Church of the Brethren, and other historic peace churches made refusal to participate in war not merely an individual choice but a durable community practice. Their experience matters at the institutional level: convictions were sustained by mutual aid, alternative service, care for those harmed by violence, and sometimes mediation. None of this resolved every question about the state and public security. But it showed that a belief could be lived and passed down across generations.

Other communities made the refusal to bear arms a way of life. In 1895, for example, Doukhobors in the Russian Empire publicly burned weapons they possessed. As a religious community, they rejected participation in violence. The authorities responded with punishment for refusing military service and other forms of persecution. Assistance from Tolstoy, Quakers, and sympathizers helped some Doukhobors migrate to Canada near the end of the nineteenth century. Their story is not one of conscience triumphing without cost. People paid for their decision through suffering, displacement, and the loss of familiar lives. But it reveals the distance between wishing that no one would fight and personally bearing the consequences of refusal. ^[21]

Political peace movements also expanded during the nineteenth century. Their members sought to change not only individual behaviour but the rules governing relations between states. They called for international arbitration, the development of law, and arms limitations. In her novel Lay Down Your Arms! (1889), Bertha von Suttner portrayed war in a way that brought its human cost home to a broad readership. Jane Addams connected peace with democracy, social reform, and the protection of vulnerable people. These figures did not always share an absolute prohibition on force. They were united by an effort to build institutions that would require states to search for alternatives to war. ^[5]

In April 1915, as the First World War raged, women from belligerent and neutral countries gathered in The Hague. Among the organizers were physician and reformer Aletta Jacobs and Jane Addams, who chaired the congress. The delegates could not sign a peace treaty or force governments to end the fighting. They could, however, discuss international mediation and democratic oversight of diplomacy. Delegations later attempted to bring their proposals to national leaders. The congress gave rise to the organization eventually known as the Women's International League for Peace and Freedom. The war continued for three more years, but the participants kept working toward the kind of peace that would have to follow it. ^{[20] [39]}

The history of pacifism has taken several paths: individual moral refusal, communal life, international law, and organized resistance. What these paths share is opposition to war. They differ in their views of permissible means and obligations to others.

4. Tolstoy: refusing to answer evil with evil

One of the most persistent voices against war in Russian literature belongs to Leo Tolstoy. He completed The Kingdom of God Is Within You in 1893. Translations appeared abroad that same year; the first Russian-language editions published outside the Russian Empire came later. In the book, Tolstoy challenged not only state violence but the human habit of transferring moral responsibility to an order, an office, or a law. An act that would be treated as a crime in ordinary life does not become morally innocent merely because a state commands it. For Tolstoy, compulsory military service was the ultimate test of this conviction. ^[35]

His argument led to a critique of the entire system of obedience. Who decides to wage war, who carries out the order, and who is responsible for a person's death? The politician invokes the needs of the state; the commander invokes military duty; the subordinate invokes the commander's instructions. Somewhere along this chain, the person accountable for the act seems to disappear. Tolstoy refused to accept the chain as an excuse. His question remains difficult even for those who reject his radical nonresistance: is an order's legality sufficient to establish its moral legitimacy?

Tolstoy's nonresistance should therefore not be confused with doing nothing. Refusing to participate in killing, openly criticizing authorities, helping persecuted people, and accepting punishment oneself are actions. They demand practical courage as well as moral resolve. Tolstoy was, however, much more suspicious of coercion of any kind than many later advocates of civil resistance. His central concern was not how to compel rulers to concede more effectively, but what a person could do without betraying their conscience.

Conscientious objectors have often paid for their decisions with freedom, work, homes, and relationships. Refusing to carry a weapon is not cowardice simply because it is a refusal. But a person's willingness to suffer does not automatically answer the question of another person's suffering. There is a difference between refusing to kill oneself and demanding the same refusal of someone who is under attack and facing death. Between a voluntary moral choice and a demand that someone else bear the cost of that choice lies a boundary pacifist philosophy cannot afford to ignore.

One of the sharpest later critics of Tolstoy's position was the émigré philosopher Ivan Ilyin. His On Resistance to Evil by Force (1925) emerged from arguments about the Russian Revolution and the armed struggle of the White movement against Bolshevism. Ilyin maintained that stopping grave wrongdoing by force might sometimes be a duty, yet even necessary violence does not become righteous: the person resorting to it bears moral responsibility for what they do. Nikolai Berdyaev strongly challenged the book in 1926. Ilyin's later writings also expressed approval of aspects of fascism, which makes the political history of his ideas important to acknowledge without dismissing the question he posed. ^[35] Could someone who could have stopped an attack but chose not to intervene be entirely free of responsibility for the victim's fate? The Tolstoyan tradition offers a warning in return: someone who authorizes themselves to use violence in the name of good may mistake moral conviction for an unquestionable right to do harm. Stopping wrongdoing is not the same as claiming the right to decide, without accountability, who embodies evil.

This dispute is not a contest between a “virtuous pacifist” and a “cruel defender of force.” Both may begin with a duty to protect human beings while drawing the limits of intervention differently. Tolstoy asks us to examine our means; Ilyin's objection asks us not to forget the consequences of inaction. One danger is to justify cruelty by calling it “protection.” Another is to leave someone in need of help alone with an attacker in order to preserve one's own principle. Here begins the most demanding part of the discussion: how can a person remain committed to refusing to kill without becoming indifferent to those under threat?

5. Gandhi, King, and the transformation of nonviolence into public power

Mahatma Gandhi did not simply adopt Tolstoy's critique of violence. He brought together several traditions—Indian ahimsa, religious ethics, personal discipline, and ideas from Tolstoy, Thoreau, and other thinkers—in the practice of satyagraha. At its centre was resistance to injustice without seeking to destroy the human being one resisted. Refusing to sustain an oppressive system, breaking an unjust law, boycotting, and engaging in mass civil disobedience turned moral conviction into political action. Participants knew in advance that arrests and repression might follow. Nonviolence did not replace conflict with pleasant feelings. It made it possible to conduct conflict by other means. ^[6]

Gandhi's own life does not support a picture of his method as flawless or unchanging. At different times, he organized ambulance units that supported British military efforts. In 1918, he personally took part in a campaign to recruit Indians into the army, as letters and publications from that period attest. ^[33] His positions on caste, colonial rule, and permissible forms of resistance evolved, and some of his later recommendations drew serious criticism. Acknowledging these contradictions does not require rejecting satyagraha. It means rejecting the weak argument that an ethical principle is true only if its best-known advocate never makes a mistake.

Gandhi's example also attracted serious objections. In an open letter in 1939, the philosopher Martin Buber challenged the applicability of Gandhi's advice to Jews facing persecution in Nazi Germany. He doubted that methods used under British colonial rule could protect people from Nazi persecution with comparable force. George Orwell later raised a related question in his essay “Reflections on Gandhi”: what becomes of nonviolent resistance when an opponent does not depend on public consent and need not tolerate open protest? These critics did not establish that any means of warfare are morally acceptable. They did, however, expose an assumption that demands testing: can the proposed method actually protect people from the particular adversary they face? ^[38]

Alongside Gandhi stands Abdul Ghaffar Khan, a leading figure in the Khudai Khidmatgar movement among Pashtuns in British India. Its members combined Muslim religious traditions, service to society, and disciplined nonviolent resistance to colonial rule. Ghaffar Khan is often described as Gandhi's disciple. That is not entirely false, but it is too narrow: it obscures the movement's own history, religious language, and social setting. ^[7]

Anthropologist Mukulika Banerjee has shown how Khudai Khidmatgar members reinterpreted familiar ideas about honour, courage, and social duty. Colonial writing often portrayed Pashtuns as naturally inclined toward violence. The history of this movement sits uneasily with that stereotype. People did not have to abandon their culture to learn nonviolent resistance. They found resources for it within values they already knew. Refusing weapons did not necessarily mean refusing courage; under repression, it could demand courage of an especially difficult kind. ^[7]

In the United States, Martin Luther King Jr. developed political nonviolence in the struggle against racial segregation. Boycotts, marches, civil disobedience, and a willingness to bear public consequences formed part of a strategy intended to change laws and social relations. King connected that strategy with the Christian understanding of love for one's neighbour, but love did not mean consenting to humiliation. Nonviolent resistance was meant to make injustice visible, change the conditions that sustained it, and avoid treating an opponent as a being without dignity. ^[8]

For King, self-defence ceased to be an abstract question after a bomb exploded at his home in Montgomery in January 1956. Relatives and friends feared another attack and urged him to arrange armed protection. King and his associates sought a permit from the sheriff for a night guard to carry a firearm but were refused. According to King's own recollections, a pistol was already in the family home at the time. Following further discussions with Coretta, the couple eventually chose to remove firearms from their home, install floodlights, and hire unarmed guards. Views on armed self-defence differed within the civil rights movement. King's personal choice was not a rule for every participant. But the episode reveals the tension between his family's safety and the method of resistance he had chosen. ^{[23] [40] [8]}

A very different example comes from the women's peace movement in Liberia. In 2003, women from different religious and civic groups demanded an end to the civil war, organized public actions, and pressed the parties involved in the talks in Accra. Leymah Gbowee was among the movement's leaders. It would be misleading to credit the movement alone with ending the war: regional diplomacy, the military situation, international pressure, and decisions by political leaders also shaped events. Yet the women's public presence disrupted a familiar arrangement in which those with weapons had the greatest say in how war might end. They demanded a voice in decisions on which their lives depended. ^[22]

These movements operated in different societies and circumstances. Each nevertheless showed that resistance is not synonymous with the use of weapons. Withdrawing everyday cooperation can change relations between governments and populations. Success depends on organization, broad participation, and the characteristics of an opponent. How reliably does this work, and where are its limits? That is no longer only a philosophical question. Historians and researchers of mass movements have tried to answer it.

6. Why pacifism deserves serious philosophical consideration

Begin with the value of each human life. In ordinary civilian life, intentionally killing someone is treated as such a grave act that it demands extraordinary justification. Why, when a war begins, does the moral burden sometimes seem to disappear, while a human being becomes a “target,” an “asset,” or a “loss”? Pacifism asks us not to lose sight of individual human lives in administrative and military language. Soldier, civilian, adversary, prisoner: these terms describe different circumstances and legal positions, but none cancels human dignity. The argument need not immediately lead to an absolute prohibition on all defence. It does, however, shift the burden of explanation. Not only the pacifist who refuses to kill, but also the person who considers lethal force necessary and permissible, must account for their position.

A second argument concerns ends and means. If the hoped-for outcome is a society that protects life and restrains power, the means used to reach it cannot be wholly irrelevant to the society that follows. People learn obedience and domination, hostility and cooperation, fear and trust not only from speeches but from practice. An institution built through terror does not automatically become free after victory. The claim that violence always produces more violence is not an established law. History includes cases in which limited force helped stop atrocities. But the risk of carrying violent methods into ordinary institutions is too serious to dismiss as secondary.

A third argument is epistemic: it concerns the limits of what we know. Wars are fought by people vulnerable to fear, group pressure, and error. States act on incomplete information. Societies hear far more about the other side's crimes than their own. Long-term consequences are almost impossible to calculate precisely. Just where the stakes are highest, the capacity for calm verification is often weakest. Some contemporary pacifists therefore argue that even if a war could be just in theory, we often lack sufficiently reliable grounds for declaring that a particular war meets all the necessary conditions.

A fourth argument concerns dehumanization. Political rhetoric can make mass killing easier to justify by replacing people with sweeping categories. Individual lives, doubts, actions, and the possibility of change vanish from view. Criticizing dehumanization does not mean refusing to call aggression aggression or a crime a crime. We can firmly condemn someone's actions and demand protection for victims without denying the offender's humanity. This distinction matters not only after war, when reconciliation may begin, but during conflict, when hatred can erode the limits of permissible action.

A fifth argument concerns the future costs of decisions made now. Death, devastated public services, displacement, trauma, long political consequences, and growing distrust do not vanish when the shooting stops. But recognizing these consequences does not prove that resistance always causes more harm than refusing to resist. A consequentialist defence of pacifism must compare real alternatives and acknowledge uncertainty. Otherwise, an ethics of consequences becomes another dogma.

These arguments matter even to people who do not identify as pacifists. A defender of limited self-defence can still regard killing as tragic and insist on strict proportionality. The disagreement begins when we must decide whether a threat can override the initial prohibition. What is the proposed war intended to achieve? Have other methods been tested? Who will bear the greatest losses, and who will be accountable for a mistake? Words such as “necessity,” “security,” and “last resort” do not answer those questions by themselves. Everyone who cares about human life has reason to demand a rigorous justification for the use of force.

7. The hardest question: must a pacifist protect someone else?

Imagine not a war or a geopolitical crisis, but a room in which an adult is threatening to kill a child. A witness is present and could intervene. If the only effective way to stop the attacker would seriously injure them, what should someone who regards violence as impermissible do? This example does not automatically justify every war. It does, however, reveal a genuine conflict of values: the prohibition against harming an attacker comes into tension with the duty to protect someone who never chose to become a victim.

The philosopher Jan Narveson offered a well-known criticism: it is difficult to separate a person's right to life from the right to defend that life against violation. The debate is not simply about practical calculations but about the structure of rights themselves. Yet a right to defence is not a right to use arbitrary means. Necessity, proportionality, and the distinction between the culpable and the innocent remain central to contemporary philosophy of self-defence. An example of legitimate defensive action does not, by itself, justify organized warfare. ^[9]

Pacifists can respond in different ways. One says that even under threat of death, they may not kill another person: that is the limit conscience imposes. Another permits unarmed physical intervention and restricted coercion but rejects intentional killing. A third allows for a tragic exception while retaining a general presumption in favour of nonviolence. To present these answers as one would distort pacifism itself.

It matters here to distinguish causing harm from stopping a threat. A person may restrain an attacker or separate people who are fighting without intending to inflict pain, much less kill. But may one physically restrict another person's freedom without consent? Where does protection end and punishment begin? The word “nonviolence” cannot answer these questions on its own. We need to distinguish intention, means, and the foreseeable consequences of intervention.

The problem becomes harder still when it is not one's own life that one is free to risk, but someone else's. A person may voluntarily accept danger for the sake of principle. But may they accept it on behalf of a child, a neighbour, or a persecuted minority? Who bears responsibility if refusing to intervene leads to a preventable death? Absolute pacifism has no universally accepted answer that removes the moral cost of such a choice. Pretending otherwise would diminish the victim's predicament.

The assertion that “there was no other choice” also deserves scrutiny. Nonviolent methods of public protection are often explored far too late, when other options have disappeared or a disaster is already under way. Where mediation, early warning, safe evacuation routes, rights-protecting institutions, civil noncooperation, and independent civic networks have been developed in advance, the available choices may be wider. That guarantees no individual will be saved. But the accusing philosophical question—“what would you do right now?”—needs a political companion: “why did we allow ourselves to arrive at a moment with only these two options?”

The history of mass atrocities puts such reasoning to a severe test. One successful rescue cannot prove that nonviolence can halt every atrocity. But a tragic failure of peaceful methods cannot prove that they are always useless. We must examine the particular circumstances: who acted, on whom people's safety depended, which resources were available, and whom it was possible to protect.

Between 27 February and 6 March 1943, mostly non-Jewish German wives and other relatives gathered outside a building on Rosenstrasse in Berlin. Around 2,000 people were held inside, mainly Jewish men married to non-Jewish partners and children of such marriages. The protesters could not know whether their loved ones would be deported, and they persisted despite threats. Historian Nathan Stoltzfus argues that this public resistance was decisive in securing the releases. The United States Holocaust Memorial Museum offers a different explanation: the Gestapo had already intended to exempt these detainees from deportation to Auschwitz and was checking their papers. The demonstrators' position as non-Jewish German family members was an important political condition of this unusual protest. Scholars dispute the causal role of the demonstration, and neither the releases nor the protesters' courage proves that the same methods could have stopped the Holocaust as a whole. ^{[25] [37]}

In the autumn of 1943, in Denmark under Nazi occupation, residents and members of the resistance helped approximately 7,200 Jews escape to neutral Sweden. Hundreds of family members who were not Jewish escaped alongside them. People were warned of danger, hidden, brought to the coast, and taken across by boat. The result was extraordinary, but it depended on particular conditions: Sweden's proximity and willingness to receive refugees, and the circumstances of the occupation of Denmark. Not everyone was saved. To blame other Holocaust victims for failing to secure the same outcome would be historically unjust. ^[24]

These cases show why moral evaluation cannot rest only on the beauty of a rescuer's actions. What matters is whether someone received shelter, a route to safety, assistance, and protection. Some saved lives through unarmed resistance. Others did so by refusing to cooperate with persecutors. We cannot demand heroism from victims according to a philosophical plan written in advance. But we should recognize and value real forms of help even when they cannot remove every danger.

8. Why just war theory is a serious challenge

The strongest criticism of pacifism need not celebrate war. Just war theory begins by recognizing the moral gravity of armed force, then seeks to define strict conditions under which its use might be permitted. They include just cause, necessity, proportionality, a reasonable prospect of achieving a protective aim, and discrimination between military targets and civilians. The meaning and foundations of these conditions remain subjects of extensive debate in contemporary philosophy of war. ^[10]

A defender of just war theory argues that refusing limited force can sometimes cause even greater harm. The pacifist faces the inverse difficulty: who determines that the criteria have truly been met, and how, when decisions are made by interested governments amid fear, propaganda, and secrecy? Both sides can take human rights seriously. They differ over permissible exceptions and the reliability of the procedures through which societies declare their actions necessary.

It is also essential to distinguish aggression from defence. Recognizing the dignity of people on both sides of a conflict does not make aggression and resistance to aggression morally equivalent. Refusing to dehumanize an adversary does not mean refusing to establish responsibility, protect victims, investigate crimes, or name those responsible. A peace movement must respect this distinction. Otherwise, a demand that “everyone lay down their arms” can become, in practice, a demand directed above all at the people under attack to abandon their defence.

For clarity, we must distinguish the legal right of states to use force from the moral evaluation of any particular use. The Charter of the United Nations requires the peaceful settlement of disputes and prohibits the threat or use of force against a state's territorial integrity or political independence, or in any other manner inconsistent with the purposes of the United Nations. Yet it preserves the right of individual and collective self-defence after an armed attack until the Security Council has taken the necessary measures. Under Chapter VII, the Security Council can also authorize measures involving force, including under Article 42. International law is therefore not a code of absolute pacifism. It seeks to reduce opportunities for aggression while setting limits on lawful defensive action. Pacifists may regard that framework as insufficient, but should not describe it as though no exceptions exist. ^[26]

Even where the decision to use force is considered lawful, a separate question remains: how is that force used? A right to engage in an armed conflict does not entail a right to attack civilians indiscriminately, torture people, or ignore the distinction between military objectives and the civilian population. Philosophers commonly discuss this through the distinction between jus ad bellum—the conditions for resorting to war—and jus in bello—the rules governing its conduct. The distinction matters to theorists and decision-makers alike. A morally defensible purpose of protection cannot make every means morally defensible.

Michael Walzer brought a particularly unsettling question into the modern debate: can an extraordinary threat to the survival of a political community justify breaking ordinary moral restraints, even to the point of intentionally killing innocent people? His argument about supreme emergency has faced criticism precisely because it risks making civilian immunity conditional on a state's fear for its existence. Critics, including Michael Neu, have examined whether and when an emergency changes an agent's moral position at all. To a pacifist, such exceptions look like a dangerous fracture in the rule protecting life. To an opponent of pacifism, refusing even to discuss emergencies can mean turning away from a real choice between terrible outcomes. The dispute is revealing because both sides may condemn attacks on the innocent while disagreeing about whether morality ever permits tragic departures from the prohibition. ^[27]

9. Does nonviolence win? What the research actually shows

Can we test how effective nonviolent resistance is? Listing Gandhi's and King's victories is not enough. We need to compare many movements, successful and unsuccessful, and ask how they operated and what they achieved. One of the most influential attempts was Erica Chenoweth and Maria J. Stephan's Why Civil Resistance Works. The authors studied 323 major campaigns between 1900 and 2006. In their original publication, they reported that nonviolent campaigns achieved their goals substantially more often than armed campaigns. Corrections to that research appeared in 2026, and a renewed debate has questioned the strength of some initial conclusions. Understanding the methods and limits of comparison matters more here than memorizing one striking statistic. ^[11]

First, we must understand what counted as a campaign. The researchers examined mass movements pursuing major political goals: regime change, independence, or an end to foreign occupation. Campaigns were classified by their predominant method and whether they attained their stated objectives. This approach is useful, but questions remain. How should we classify a movement combining strikes with armed clashes? What about small protests suppressed before they could become mass campaigns? Researcher Christoph Dworschak identifies a further problem, sometimes called the “streetlight effect”: failed or less visible nonviolent campaigns may be missing from historical records, affecting the comparison itself. ^[13] Where is the line between partial and complete success? Statistics tell us little until we know which events were included.

Chenoweth and Stephan proposed a mechanism that might explain the observed difference. Joining an armed uprising requires weapons, training, and a willingness to face lethal danger. Boycotts, strikes, and civil disobedience can involve a much wider range of people. Broader participation makes it harder for authorities to maintain customary economic and administrative relationships. At times, the loyalties of officials or security forces may shift as well. Gene Sharp examined the underlying mechanism in detail in The Politics of Nonviolent Action (1973): political power relies not only on coercion, but also on the cooperation of the governed. Neither mass participation nor a movement's moral legitimacy, however, guarantees victory. ^[36]

Another problem is causation. Suppose civic organizations are strong in one country, the ruling elite is already divided, and the government's international allies are wavering. In another, independent organization has been largely destroyed and resistance turns to arms. If the first movement succeeds and the second fails, can we attribute the difference to the choice of strategy alone? Perhaps not: the countries differed from the outset. Statistical models can account for some of these differences but do not automatically eliminate them. That is why observed differences in success rates cannot, on their own, establish that the chosen tactic caused the outcome.

We must also decide which outcomes matter. Replacing a government does not guarantee freedom or safety. A movement may fail to achieve its central goal yet still save lives, interrupt particular forms of repression, or preserve independent organizations. Conversely, a formal political victory may involve substantial loss of life, new violence, or the breakdown of social ties. The boxes marked “success” and “failure” are insufficient for moral judgment. We also need to consider the human cost, the position of vulnerable groups, and the condition of society after political change.

Research has continued. In 2022, Chenoweth and Christopher Wiley Shay presented NAVCO 2.1, an updated dataset covering 389 major nonviolent and armed campaigns from 1945 to 2013. They refined campaign classifications and information on individual campaign years. Several trends emerged in this sample. The success rate of nonviolent campaigns declined after 2001. Nonviolent campaigns generally involved more participants than armed ones, and fatalities per participant were markedly lower. Yet the dataset does not cover every kind of conflict. Even identifying a trend does not, by itself, explain why it occurred. ^[12]

Digital surveillance, for example, may have given authorities new means of repression. International circumstances and the organization of mass movements have changed too. We should not select one plausible explanation and pronounce it proven without comparative evidence. For the same reason, the observation known as the “3.5 percent rule” must not be read as an instruction manual, as though a movement automatically wins whenever a certain share of the population participates. Historical observations provide no such guarantee. Organization, state responses, allies, the scale of the threat, and the movement's aims can all change its prospects. ^[32]

In April 2026, Chenoweth and Stephan published corrected tables for their original study. In May, Charles Crabtree and John Holbein released a preprint arguing that some statistical results had been misreported and that the claimed causal advantage of nonviolent campaigns was not robust to reasonable changes in model specification. They did not argue that nonviolence was inherently less effective or harmful. In a reply published later in 2026, Chenoweth and Stephan challenged the broader conclusion, pointing to evidence accumulated beyond the original book and to the greater human costs of armed resistance. Their response notes that even a finding of similar probabilities of political success would not mean similar human costs. The methodological disagreement remains unresolved; it matters both how success is measured and what people pay to achieve it. ^{[11] [14] [15]}

Finally, the scope of this research imposes a strict limit on the conclusions we can draw. A civil campaign seeking to replace a government and the defence of a country facing foreign invasion are not the same kind of conflict. The means of influencing an opponent, possibilities for participation, nature of the threat, and objectives all differ. We cannot take statistics from protest movements as proof that armed defence is never needed. Nor can we dismiss every nonviolent method simply because it offers no universal guarantee of safety. Research becomes useful when it helps us understand what works, for whom, under which conditions, and at what cost.

10. Unarmed protection: real practice, real limits

Between refusing to cause harm and doing nothing lies a wide range of ways to protect people. Civilian groups help people reach safer places, warn of threats, and accompany those at risk. They negotiate with armed actors, document abuses, and sustain relationships between neighbours. In international practice, these activities are often grouped under the name unarmed civilian protection. The term covers several methods; it does not promise that each will succeed.

Evidence about these practices comes from field studies, comparative reviews, and reports by the organizations involved. Its quality varies. In some settings, researchers can observe changes in community safety. In others, the available evidence consists mainly of interviews and descriptions of individual cases. Unarmed protection can influence armed actors who care about local legitimacy, international attention, or community cooperation. Where attackers intend to destroy a population and do not depend on its support, those mechanisms may be inadequate. The mere presence of observers cannot stop artillery fire.

South Sudan offers an instructive example. Women's protection teams have helped identify threats, accompany vulnerable people, and seek responses to sexual and gender-based violence. Researcher Louise Ridden describes the role of women's social standing. Older women could sometimes speak to influential men and draw attention to abuse that younger women found harder to report openly. They were perceived as posing less of a threat to existing hierarchies. That did not make them invulnerable; the women acting as protectors faced danger themselves. Yet their relationships sometimes helped secure assistance for others. ^[28]

Such experiences challenge the familiar division between a powerful “protector” and a helpless person “being protected.” People facing violence may know more about local disputes, relationships, and possible escape routes than an outside specialist. An external organization may bring training and resources, but it must earn local trust. Protection is created together; it is not always something one side simply provides to another.

This approach also has dangerous limits. In a systematic review, Urban Reichhold examines ways civilians resist rebel groups, ranging from discreet assistance and noncompliance to open protest. The opportunities and risks depend on the armed group's character, its relationship with the population, and the potential for reprisals. Individual success stories do not establish that the method offers safety in every setting. Comparable cases and honest reporting of failures are especially important here. ^{[29] [31]}

We must not ignore evidence concerning United Nations peacekeeping operations, either. Some studies have associated the presence of sufficiently large military and police contingents with reduced violence against civilians. That does not make every armed intervention effective or permissible. It does make it difficult to insist that weapons can never be used for protection. A more useful approach compares particular tasks: warning of danger, securing an escape route, accompanying people, separating opponents, or stopping an immediate attack. In each case, we should ask which means can preserve more lives with the least harm. ^[30]

Conscientious objection to military service is a related but distinct issue. It is connected to the fundamental freedom of thought, conscience, and religion. The United Nations Human Rights Committee addresses conscientious objection in relation to the freedom of conscience protected by the International Covenant on Civil and Political Rights. In 2011, the European Court of Human Rights decided Bayatyan v. Armenia, finding that punishing an applicant for refusing military service on sincerely held religious convictions had violated his freedom of conscience. This does not mean the right is implemented equally in every country, particularly during war or mobilization. But recognizing freedom of conscience means accepting that a state's decision to use force does not erase an individual's moral responsibility. ^[16]

Ultimately, the results of protection must be judged by what happens to particular people. Was an attack prevented? Did someone reach a safe place? Were they subjected to violence again? Peaceful methods deserve development not because they are guaranteed to be right, but because every demonstrated instance of protecting life matters. Testing their limits is part of the same responsibility as improving the ways we help.

11. Pacifism and the challenges of the twenty-first century

Technology is forcing us to revisit old questions about violence. Nuclear weapons carry risks of destruction that are especially difficult to reconcile with proportionality and the protection of civilians. That is why some people reject nuclear warfare without regarding themselves as absolute pacifists. Autonomous weapons and the use of artificial intelligence in target selection add new questions: who makes the final decision, who is accountable for mistakes, and can human beings retain meaningful control? International humanitarian law continues to apply to autonomous systems. Yet the predictability of their behaviour, the selection of targets, and human oversight present serious challenges to meeting its requirements. ^[41]

What we know about human behaviour also gives us little reason to settle for simple slogans. The human capacity for violence is real, but it does not follow that war is biologically inevitable. Human beings can cooperate and act cruelly; institutions, education, and political decisions help shape how those capacities are expressed. The 1986 Seville Statement on Violence challenged the idea that war is genetically predetermined. Its historical significance is considerable, but individual scientific claims must be assessed in the light of research conducted since its adoption. ^[34]

Ideas about nonviolence also extend beyond relationships among human beings. Some ethical and religious traditions include animals and other sentient creatures within the sphere of moral concern. This raises further questions about permissible harm, but it is not part of the necessary definition of pacifism. Expanding the moral circle in this way requires arguments of its own. Peaceful World explores this topic in a separate study of ahimsa. ^[17]

Education has a particular role to play. A person can read an article about dehumanization and still engage in it when speaking about their own group and its opponents. Knowledge does not automatically become a skill. Peace education should therefore be evaluated at least at three levels. First, access: did a person receive material in a language they understand? Second, understanding: did they become better at distinguishing arguments and recognizing their own errors? Third, behaviour: does their new understanding help them choose a less harmful response in a difficult situation? There is no guaranteed passage from one level to the next.

UNESCO's 2023 Recommendation offers international guidance on education for peace and human rights. But even an excellent policy document does not establish the effectiveness of every educational programme. Page views or agreement with a questionnaire are not evidence of changed behaviour. We need observation, learning from mistakes, and a willingness to revise our materials when new evidence emerges. That is what separates inquiry-based education from teaching people to recite a predetermined “correct” answer. ^[18]

12. Peaceful means as responsibility, not reassurance

For one person, pacifism begins with a personal decision: “I will not kill.” History contains many people who have paid for that decision with their freedom, homes, livelihoods, and sometimes their lives. But a public ethic must ask a further question. What can we do so that other people remain alive, too? When the rejection of destructive means is accompanied by no practical alternative, it can become a heavy demand placed on a victim to whom no protection has been offered.

This is the task of active pacifism. It means preventing conflicts, strengthening institutions that protect people and uphold international law, supporting conscientious objectors, developing nonviolent resistance, and assisting those harmed by violence. It also means learning to recognize the language of dehumanization before it becomes the ordinary way we speak about neighbours and opponents. None of this promises that wars will disappear for good. But every effective measure widens the space for choice where people now often see only two outcomes: kill or go unprotected.

Peaceful World's mission starts from the dignity of life and a commitment to prioritizing nonviolent means. Its current Manifesto treats protective force as a tragic exception: it may be considered only in response to an immediate threat to life, when peaceful alternatives are unavailable, and subject to strict requirements of proportionality, accountability, and subsequent repair. This is the organization's position—not a definition of every kind of pacifism, and certainly not a final resolution of the philosophical problem. Our work is to help build forms of protection that make such exceptions less necessary. ^[19]

People who disagree on important questions can cooperate toward that goal. Some understand refraining from violence as a religious duty. Others maintain a strong moral presumption against it while allowing exceptions. Still others focus on political means of preventing war. Shared work does not require pretending that the disagreements have vanished. It begins by taking the hard questions seriously. How can we protect the right to refuse to kill without abandoning a victim? How can we restrain those authorized to use force? How can we tell whether proposed nonviolent methods save actual lives?

The central question also concerns the future. What must change in education, law, and politics so that fewer people face a choice between doing nothing and using lethal force? There is no simple answer. But the absence of a formula does not make the work meaningless. Every initiative must be assessed not by the nobility of its stated aim, but by its consequences for human life and freedom.

One of the strongest interpretations of pacifism understands it not only as a refusal to kill, but as a responsibility to find ways not to kill. That search does not release us from responsibility for people in danger now. It demands courage, knowledge, and a willingness to reconsider our convictions when they fail the test of reality. Perhaps that is what mature pacifism looks like: not demanding that the world conform to a beautiful idea, but helping to create a world in which fewer people must choose between someone else's life and their own conscience.

Frequently asked questions

Is a pacifist someone who opposes every war?

Not necessarily. Some pacifists oppose all wars without exception. Others regard wars as almost always unjustified but allow strictly limited exceptions. Academic literature generally distinguishes these as absolute and conditional forms of pacifism. ^[1]

How does pacifism differ from nonviolence?

Pacifism is chiefly a moral and political position concerning war and the permissibility of violence. Nonviolence can be an ethical principle or a particular method of struggle, including boycotts, noncooperation, and civil disobedience. Someone may use nonviolent methods without accepting pacifism as a philosophy.

Does pacifism mean surrender?

No. Many pacifists actively resist injustice. Different kinds of pacifism nevertheless draw different lines around permissible forms of resistance. Calling every refusal to kill “surrender” confuses the goal of protection with the choice of means.

Can pacifists protect other people?

Yes. Many pacifists regard the protection of others as a moral duty and choose nonviolent or minimally harmful forms of intervention. When someone faces imminent death and those methods are insufficient, however, absolute and conditional approaches diverge on a fundamental question.

Has research proved that nonviolent resistance is more effective than armed resistance?

In some historical datasets of major political campaigns, nonviolent movements attained their goals more often. The strength of any causal conclusion remains contested, however, and research on civil resistance cannot simply be applied to interstate wars or the immediate defence against an invasion. ^[11–15]

Where should someone begin learning about pacifism?

A good starting point is to understand the different forms of pacifism, then read primary works by Tolstoy, Gandhi, and King before engaging with the strongest objections—particularly the duty to protect the innocent. For academic orientation, consult the Stanford Encyclopedia of Philosophy and historical research on peace movements. ^{[1] [8]}
