Introduction: Loving in Wintertime

The Shelling of Mainila is a twentieth-century conspiracy theory. In 1939, Stalin issued a series of ultimata to Finland. The Finns said “No.” So, on November 26, 1939, a border incident was arranged near the Mainila outpost. Finnish guns, claimed Stalin, had fired shells at innocent Russian border patrol troops—an allegation believed by no one outside, or possibly inside, the Kremlin. The so-called Winter War between Finland and Russia would last only thirteen wintry weeks.Footnote ¹ It was not the first time Russia had invaded one of its smaller neighbors, nor would it be the last.

In England, C.S. Lewis—the famous literary scholar and World War I veteran—had been delighted over Finland's early success: he followed the campaign intently (Lewis Reference Lewis and Hooper2004a, 311, 337, 350, 836). Why did this Oxford don who rarely read the news care so much about Nordic miseries? Lewis had what he called a “bent to ‘Northern’ things” (Reference Lewis and Hooper2004a, 171). He loved the Kalevala and was enchanted by the composer Sibelius: “Very, very Northern: he makes me think of birch forests & moss and salt-marshes” (Reference Lewis and Hooper2004a, 175). Lewis's Finnish sympathies help us to understand his sometimes-unflattering words about Russian soldiers and Russian imperialism. Joseph Stalin—or “Uncle Joe” as Lewis sometimes called him (Reference Lewis and Hooper2004b, 178)—seemed particularly unlovable to him (Reference Lewis and Hooper2004a, 408).

Lewis's nuanced thoughts about our subject—the nature and limits of enemy love—are recorded in his letters, essays, and books.Footnote ² Though Lewis found war “an odious necessity” (Reference Lewis1984, 188), he warned against demonizing one's opponents (Reference Lewis and Hooper2004a, 391). Consider, for example, his hope that if he and a German soldier had killed each other simultaneously and met a moment after death, “I cannot imagine that either of us would have felt any resentment or even any embarrassment. I think we might have laughed over it” (Reference Lewis2001, 119, emphasis added). Behind such optimism was his belief in the nobility of death for a good cause (beyond even this world) but also first-hand experiences and stories of outbreaks of humanity even during combat, such as the now-famous Christmas truce of 1914.Footnote ³

Political scientist Robert Axelrod's The Ethic of Cooperation (Reference Axelrod2006) begins with a discussion on how the structure of World War I's trench warfare in particular encouraged such outbreaks of humanity. But cooperation is by no means unique to trench warfare. In her study Conspiring with the Enemy (Reference Chiu2019), U.S. Naval War College professor Yvonne Chiu identifies, categorizes, and analyzes examples of the ethic of cooperation between enemies before, during, and after combat. Enemies have often collaborated to establish formal and informal practices to fight “fairly,” to minimize damage to certain classes of people, and to end war quickly. All of this happens despite and sometimes while enemies try to kill one another. What is new is the gradual codification and systematization of these practices and principles into international law, conventions, and accompanying institutions (Chiu Reference Chiu2019, 23, 31).

How far can we stretch the language of such ethics? Can we meaningfully speak of loving the enemy? In this paper, I will ask, and propose an answer, to a difficult question about enemy love, leaning on Lewis as my primary guide. The British General Sir Hugh Beach who participated in the Normandy invasion has called the question “the dilemma of the Christian soldier”: “How to reconcile the dominical injunction to ‘love your enemies’ (Matt. 5:44) with the military task of defeating, and where necessary killing, your opponent in war” (Reference Beach2015, 280)? More pointedly: Can I love my enemy and kill him? Despite the “Christian” designator, this is a perennially meaningful question for people of other faiths or no faith, as well.

Ironically symptomatic of the lack of careful scholarly attention this question has received is General Beach's own treatment of it in “Can a Soldier Love His Enemy?” (Reference Beach2015). After raising the question at the outset, he discusses the importance of ethical training of soldiers and lists some “rules of engagement” to minimize unnecessary violence, before closing and leaving the reader with the original question left unanswered: “Whether you rate it as love I leave to you” (Reference Beach2015, 286). Religious studies professor James Kellenberger's otherwise worthy study of love in religion, The Asymptote of Love: From Mundane to Religious to God's Love (Reference Kellenberger2018), completely omits any discussion of enemy love.Footnote ⁴ Modern Theology's special edition “Love Your Enemy: Its Political Significance” (Barringer and Long Reference Barringer and Long2020) fares better but never tackles the question head-on.Footnote ⁵

A political ethicist who does tackle it head-on is Nigel Biggar, the Regius Professor of Moral and Pastoral Theology at the University of Oxford: his article “In Defence of War” (Reference Beach2015) develops ideas first presented in his eponymous book In Defence of War (Reference Biggar2013). The best treatment of this subject viz. Lewis in particular is U.S. Naval Academy's Leadership Research Fellow Marc LiVecche's “C.S. Lewis, War, and the Christian Character” (Reference LiVecche2019), a study first presented at the Oxford University C.S. Lewis Society.Footnote ⁶ Both Biggar and LiVecche make several pertinent points, and I can follow them much—but not all—of the way.

Lewis himself was personally quite fond of the season of winter. But in his poems and especially in his classic The Chronicles of Narnia, winter is a metaphor for circumstances most unfavorable: “Always winter and never Christmas; think of that!” (Lewis Reference Lewis2004c, 118). Or always Winter War and never Christmas truce; think of that. So, how do we love in the winter? How do we love when the sky is dark and the days are short, when the forests are frozen and the marshes are martial, when our fingers and our hearts are numb?

I begin by defining “love,” “enemy,” and “enemy love.” I then turn to Lewis's general views on war and pacifism, which are informed by both politics and religion. This will put us in a good position to address the main theme, the compatibility of love and war, and how each might qualify the other in important ways. Finally, we finish with a discussion on the enemy's wellbeing or flourishing. Can it ever be in someone's best interest to suffer injury or death? Insufficient ethical precision has often obscured the moral ambiguity in the act of taking a life. Lewis's distinction between “relative” and “absolute” love will prove helpful in untangling some of the ethical and practical knots involved.

A Working Definition of Enemy Love

It is impossible to solve problems of “enemy love” before we define “enemy” and “love.” And as so often happens, defining words half answers questions. Let us begin with love.

Lewis's famous treatise on love, The Four Loves (Reference Lewis1960), discusses various “elements,” “types,” and “levels” of love. The “four” types of love—Affection, Friendship, Eros, and Charity—do not exhaust love. The book opens with a discussion of what Lewis calls the three “elements” of love—need-love, gift-love, and appreciative love—which permeate all four types of love. Lewis also includes sections on love of animals and love of country. The compatibility between enemy love and killing is not discussed directly. But Lewis argues that healthy patriotic love must lead to the recognition that people from other places rightly love their homes, too. The natural stance towards the “other” is one of goodwill. “Of course patriotism of this kind is not in the least aggressive. It asks only to be let alone. It becomes militant only to protect what it loves. In any mind which has a pennyworth of imagination it produces a good attitude towards foreigners” (Lewis Reference Lewis1960, 34).

As I have argued more carefully elsewhere (Lepojärvi Reference Lepojärvi2015, 68–71; Lepojärvi Reference Lepojärvi2022), Lewis nowhere gives a sufficiently clear definition of love itself, the common denominator of all loves, but an approximate essence of love can be extracted from The Four Loves and his many other writings on the subject. For the purpose of this paper, I find this definition useful: Love is the appreciative and responsive commitment to the other's wellbeing insofar as possible and permissible. As such, the virtue or skill of love has not just attitudinal but also practical and relational aspects. You can fail in one aspect of love without necessarily failing in the others, and vice versa. In the absolute fullest sense, however, what love “says” to the beloved—be they friend, family, or foe—is effectively: “It is good that you exist! I will involve myself in your wellbeing insofar as I am able, and I welcome your love in return.”

If this is love, what, then, is an enemy? In the Christian tradition, everyone is your “neighbor” but some people are easier to love than others. Enemies are obviously in the “difficult” camp, but not all difficult people are our enemies. An enemy-neighbor is a difficult-neighbor whom it is difficult to love for a specific reason. The two things that arguably most threaten loving one's enemies are resentment and the prospect of violence or injury. It follows that our “enemy” is someone whom we find difficult to love because we feel resentment towards them and/or they seek to injure us. I have analyzed the nature and role of resentment in the enemy-relation elsewhere (Lepojärvi Reference Lepojärvi2023); the present paper addresses the latter relation, that between love and violence.Footnote ⁷ One may or may not resent an enemy in this sense, but they actively threaten someone's wellbeing.

By defining both enemy and love we have as a happy by-product discovered a helpful understanding of enemy love, as well. Enemy love is the appreciative and responsive commitment insofar as possible to the wellbeing of someone we feel resentment towards and/or who seeks to injure us. This will be our working definition of enemy love. For confessing Christians, such as C.S. Lewis, enemy love is absolutely binding. “Love your enemies,” commanded Jesus, “do good to those who hate you, bless those who curse you, pray for those who mistreat you” (Luke 6:27–8). Though a Christian duty, enemy love is not unique to Christianity. “I shall never forget my surprise,” Lewis writes in Reflections on the Psalms, “when I first discovered that St Paul's ‘If thine enemy hunger, give him bread,’ etc., is a direct quotation from [Proverbs 25:21]” (Lewis Reference Lewis2017, 30).Footnote ⁸ The Christian covenant does not change the meaning or scope of love (as if, e.g., enemies were previously excluded), but Jesus reiterates the command to love and highlights that God, too, loves sinful people in this way.

I next turn to Lewis's general views on war and pacifism. This will prepare the way for our main question, which General Beach called “the dilemma of the Christian soldier.” Just as readiness to die in battle might be seen as the ultimate test of fortitude, war or violence in general is possibly the ultimate test of enemy love. Are love and violence compatible? Can a soldier love his enemy? Can killing ever be an expression of love?

C.S. Lewis on War and Pacifism

Though optimistic about posthumous encounters between enemy combatants, Lewis was anything but blasé or enthusiastic about war. The pacifist theologian Stanley Hauerwas's critique of Lewis on war begins with a four-page defense of him against any such suspicion. As a survivor of World War I, says Hauerwas, Lewis had “no time for the sentimental glorification of battle” (Reference Hauerwas, MacSwain and Ward2010, 190). Lewis even faults his own mentor G.K. Chesterton for being “enchanted” by war: he has “no idea what a battle is like” (Lewis Reference Lewis and Walmsley2000, 691). “My memories of the last war haunted my dreams for years,” Lewis confessed (Lewis Reference Lewis and Hooper2004a, 258). Of the six young men with whom he trained before going to war, four died and two were wounded, Lewis badly and by “friendly fire” (Duriez Reference Duriez and Edward2007, 79).Footnote ⁹ J.R.R. Tolkien, who later befriended Lewis, wrote of his similar war experience: “By 1918 all but one of my close friends were dead” (Tolkien Reference Tolkien2007, xxvi).Footnote ¹⁰

When another European war was imminent, the anxious Lewis wanted to “hibernate.” It was worse than that: “I think death wd. [would] be much better than to live through another war,” he tells his friend Dom Bede Griffiths (Reference Lewis and Hooper2004a, 258). He even says his goodbyes to another dear friend Owen Barfield: “[O]ur whole joint world may be blown up before the end of the week… If we are separated, God bless you, and thanks for a hundred good things I owe to you, more than I can count or weigh” (Reference Lewis and Hooper2004a, 232). Lewis believed that war threatened every temporal evil. And yet, to Griffiths again: “I'm not a pacifist. If its [sic] got to be, its [sic] got to be” (Lewis Reference Lewis and Hooper2004a, 258). Sometimes war was an odious necessity.

Lewis's most developed views on war and pacifism are included in his two wartime essays, “Why I Am Not A Pacifist” and “The Necessity of Chivalry.” As so often for Lewis, their main points were first articulated in letters. In fact, his pre-war letter to Griffiths in 1938 is almost a synopsis of both essays. It begins with “I have always believed that it is lawful for a Christian to bear arms in war when commanded by constituted authority unless he has very good reason […] for believing the war to be unjust” (Lewis Reference Lewis and Hooper2004a, 233) and ends with “I cannot believe the [chivalrous] knight errant idea to be sinful” (234). Lewis believed that facts, intuition, reason, and authority all supported his view. We need not rehearse his arguments here. I mention only two points about religious authority.

First, the commandment “thou shall not kill” (the first part of the “dilemma of the Christian soldier”) is, according to Lewis, not a prohibition of all violence or even all killing. It is a prohibition of murder. “Kill means murder,” he says, and “when our Our Lord quotes this commandment he uses Gk phoneuseis (murder) not apokteinein (kill)” (Reference Lewis and Hooper2004b, 246) and not just once but “in all three accounts, Matthew, Mark, and Luke. And I am told there is the same distinction in Hebrew” (Reference Lewis2001, 118–119). Second, Lewis takes “the dicta in the Sermon on the Mount to be prohibitions of revenge” (Reference Lewis and Hooper2004a, 234). When Jesus said to “turn the other cheek” he meant what he said “but with an understood reservation in favour of those obviously exceptional cases which every hearer would naturally assume to be exceptions without being told” (Reference Lewis and Walmsley2000, 291). “Does anyone suppose,” he asks a pacifist audience, “that Our Lord's hearers understood Him to mean that if a homicidal maniac, attempting to murder a third party, tried to knock me out of the way, I must stand aside and let him get his victim?” (Reference Lewis and Walmsley2000, 291). In my view, Lewis's footing here is strong exegetically (what the text says), historically (its dominant interpretation in Judeo-Christian tradition), and ethically (its moral soundness irrespective of text and tradition). I have minor qualms about his views on pacifism, however.

Lewis's essay on pacifism was indeed first delivered as a paper to a pacifist audience, the Oxford Pacifist Society. He felt comfortable invoking religion because he knew many of those present were religiously motivated. And he knew this because he had long been interested in conscientious objection and had recently himself heard a paper given by a former colleague “on his experiences in his present job as a member of the tribunal for investigating conscientious objections” (Lewis Reference Lewis and Hooper2004a, 344).Footnote ¹¹ Lewis summarizes the paper in his letter to his brother (an officer in the British military) on February 11, 1940: “I was interested and relieved to hear [that] the vast majority of the objectors are perfectly sincere, and often want to be put on dangerous non combatant [sic] works such as mine sweeping; and also that the communists and intellectuals are a minority—most of them are Jehovah's Witnesses, Seventh Day Adventists, etc. Often yokels, almost inarticulate” (Reference Lewis and Hooper2004a, 344–345).Footnote ¹²

Why was he relieved to hear this? Because of his prejudice. The “poor Adventists and Witnesses from remote Welsh pits and Northumbrian farms” are favorably contrasted with the “really contemptible figure” of the “typical intellectual Oxford communist undergraduate” (Lewis Reference Lewis and Hooper2004a, 345). Legal conscientious objection, he reminds his officer brother, belonged to “that simply fantastic side of English life which has always impressed foreigners but which we are apt to forget” (Reference Lewis and Hooper2004a, 344)—and, in fact, “that sort of thing is part of what we are fighting for” (Reference Lewis and Hooper2004a, 345).Footnote ¹³ This had of course not always been so. Great Britain had entered World War I without general conscription, but when this changed in 1916, pacifists were able to register as conscientious objectors or serve as non-combatants, but were often subjected to ridicule and harassment. “We must of course respect & tolerate Pacifists,” Lewis tells another correspondent, “but I think their view erroneous” (Lewis Reference Lewis and Hooper2004b, 247).Footnote ¹⁴

My issue with Lewis's views on pacifism is two-fold. The first is historical. Lewis seems ignorant of early Christian pacifism. In his letters, he calls pacifism “a v. [very] recent and local variation” (Lewis Reference Lewis and Hooper2004b, 247) of Christendom and contrasts it with “the general agreement of all Christian communities except a few sects—who generally combine pacifism with other odd opinions” (Lewis Reference Lewis and Hooper2004a, 233–234)—a clear reference to Jehovah's Witnesses, Seventh Day Adventists, and other variants quite recent in Church history. But as military ethicist Martin Cook notes, “the clear pacifist thrust of the New Testament's strong streak condemning violence and counseling nonresistance to evil” (Cook Reference Cook2013, 160) has inspired Christian pacifism from the very beginning. Early Christians may or may not have been overwhelmingly pacifists, but what patristic scholar David G. Hunter has said of Christian just war thinking applies even more so to Christian pacifism: it “stand[s] in fundamental continuity with at least one strand of pre-Constantinian tradition” (Hunter Reference Hunter1992, 93).

My second issue is with Lewis's logic. When he says that “history is full of useful wars as well as of useless wars” (Reference Lewis and Walmsley2000, 286) and “Christendom has made two efforts to deal with the evil of war—chivalry and pacifism. Neither succeed” (Reference Lewis and Walmsley2000, 768), I nod approvingly. But when he doubts “whether chivalry has such an unbroken record of failure as pacifism” (Reference Lewis and Walmsley2000, 768), I must ask: How would he know? Such comparative evaluations sound hopelessly speculative. Besides, every just war is a response to an unjust war: sometimes both sides are wrong, never are both right. It follows, by logic, that history must be fuller of useless wars than useful ones. Moreover, every time Christian pacifism has failed to prevent an unjust war, this failure is shared with Christian just war thinking (“chivalry”) that failed to prevent that very same war (Biggar Reference Biggar2013, 33), and vice versa. One might go as far as to propose a principle: Commission in unjust wars and omission from potentially just wars are shared responsibilities.

Is Lewis's comparison salvageable? By my lights, the only way to avoid possibly unfalsifiable nonsense is either (a) to emphasize quality over quantity or (b) to focus on a subset of parties involved. In other words, (a) to say that given the outbreak of an unjust war, chivalry can prevent or mitigate worse injustice than pacifism (e.g. sometimes aggressors are better resisted earlyFootnote ¹⁵) or (b) that the wars of a given country committed to chivalry can on average be more just than unjust. Some countries may have better track records than others. There is a third alternative. Lewis was an orator who sometimes took rhetorical liberties: perhaps his comment was (c) a hyperbole not salvageable by logic at all. It was a line at the end of a newspaper letter and perhaps not intended as the substantive claim I have treated it. In any case, Lewis was not a consequentialist: comparative records alone rarely settle any position.

Mars and Venus: How Love and War Qualify Each Other

Despite these minor qualms, on the more general question about love's partial compatibility with violence and war, I tend to agree with Lewis. Can violence or killing be described as “love” in any meaningful sense? My answer will be: yes and no. I agree with Biggar that to say that war is not “fully compatible” with love means that “they are somewhat compatible” (Reference Biggar2015, 198). Or as LiVecche puts it, love “qualifies, but does not eradicate, war” (Reference LiVecche2019, 6).

Excluding actual homicide, what does “violence” mean? Here, with Lewis, I apply the traditional minimalist definition limited to physicality and leave out modern extended meanings of the word: Violence is using force to deter, harm, or kill a human body.Footnote ¹⁶ The more painful, the more violent. Lewis “doubts” (Reference Lewis and Walmsley2000, 586) whether war increases the chances of painful death. Even so-called “natural death is usually preceded by suffering: and a battlefield is one of the very few places where one has a reasonable prospect of dying with no pain at all” (Reference Lewis and Walmsley2000, 586). Again, we can quibble over statistics and probabilities. There are worse things than pain, or violence, or war.

“It must be remembered,” Lewis says, “that there are risks in both directions: if war is ever lawful, then peace is sometimes sinful” (Lewis Reference Lewis and Walmsley2000, 768). Why so? Because nonviolence can sometimes be a failure to uphold justice in a broken world motivated by rightly ordered love. This is a strong argument: sometimes love prefers war to peace. But I agree with it if by peace we mean “absence of conflict” in a grossly unjust way. The object of just war remains peace, but a better, more just one. I am thinking of what Biggar calls the “evils of peace” (Reference Lewis2013, 7), “the evils, tragedies, ambiguities, risks, and uncertainties of peace” (Reference Biggar2015, 196), such things as the preventable massacres and genocides that took place in Rwanda and Srebrenica in Bosnia. As LiVecche says, “not to act is also a decision requiring some degree of justification” (Reference LiVecche2019, 9). We are morally responsible for our omissions as well as our commissions.

Love does not categorically preclude violence. It can permit and even motivate it. Lewis would certainly reject what has been called “the virus of wishful thinking” (Burn Reference Burn2003, 70; Biggar Reference Biggar2013, 9): that everybody is rational and wants what is best for the other. The anthropological fact of “sin” and historical experience contradicts this. According to Biggar, “some people cannot be talked out of grave wrong-doing and […] they must therefore be forced out of it” (Reference Biggar2015, 194). “Courts are not the only place where justice is done; the battlefield can be another” (196). Chiu summarizes the predicament thus:

According to Lewis, it follows that the fighting instinct is not bad per se. Sometimes it can be a duty to “encourage” it (Lewis Reference Lewis2001, 11).

So, I would agree with LiVecche, here approving paraphrasing the character Faramir in The Lord of the Rings, that “war can be an expression of love” (LiVecche Reference LiVecche2019, 1). But an expression of love towards whom? This is more complicated. Violence can be an expression of self-love or family-love against Lewis's “homicidal maniac.” It can be an expression of patriotic love against a homicidal nation. Above all, it can be an expression of love for the innocent victim-neighbor. Lewis writes: “I do not think punishment inflicted by lawful authorities for the right motives is revenge: still less, violent action in the defence of innocent people” (Lewis Reference Lewis and Hooper2004a, 234). “[T]o banish the knight does not alleviate the suffering of the peasant” (Lewis Reference Lewis1954, 153). According to Biggar, indeed, in the Christian tradition, the paradigm of just war is not self-defense but “the rescue of the innocent” (Reference Biggar2015, 196). Whether violence and war can be an expression of enemy love is a much more difficult question, which I will address soon.

We have all heard the maxim “all is fair in love and war.” This is doubly false. All is not fair in war. And it is precisely love that sets limits to it. Love may permit and even motivate war, but it also qualifies it. Venus qualifies Mars.Footnote ¹⁷ The guiding principle for Christians is of course the “Golden Rule” (Matt. 7:12)—treat others as you would have them treat you. The simplistic literal interpretation is impossible. I love my back scratched, my brother hates it: scratching his back is a declaration of war. The Golden Rule is a guiding principle not a mathematical formula. Applied to warfare it might go something like this: “Wage war against others as you would have them wage war against you.” This both limits legitimate reasons for entering war and curtails what may be done in war in the spirit of the ethic of cooperation. Political theorists speak of jus ad bellum and jus in bello, reasons for and methods in war, respectively.

According to Chiu (Reference Chiu2019, 204, 222, 227), considerations of jus ad bellum (except self-defense) have effectively been eclipsed by jus in bello in contemporary discussion and international laws of war. Lewis, too, spends more time discussing the latter than the former, possibly because of his general lack of interest and aptitude in international politics, his ethical training that prioritized individual responsibility, and his own wartime experiences from the grassroot perspective of foot soldiers who vastly outnumber political leaders responsible for entering or abstaining from wars.

Love qualifies when we may enter war (jus ad bellum). Hauerwas summarizes Lewis's position well: Lewis “thought it should be a last resort, declared by a lawful authority, a defensive rather than an imperialistic endeavour, that the aims of the war be limited, that there be some realistic chance of success, and that there be a willingness on the part of the combatants to take responsibility for their actions so that civilians will be properly protected” (Hauerwas Reference Hauerwas, MacSwain and Ward2010, 192).Footnote ¹⁸

Love also qualifies what we may do in war (jus in bello). Lewis explains the general principle: “lesser violence done to [an enemy or dangerous criminal] is always preferable to the greater, provided that it is equally efficient in restraining him and equally good for everyone concerned” (Lewis Reference Lewis and Walmsley2000, 286)—if you will, an “Occam's razor” with a bellicose bent. Entirely forbidden methods include murdering prisoners, bombing civilians, and so on (Lewis Reference Lewis and Walmsley2000, 768).Footnote ¹⁹ One's own moral posture is also crucial, Lewis thought. “We may kill if necessary, but we must not hate and enjoy hating” (Reference Lewis2001, 120). Just war requires just soldiers or “knights,” as Lewis calls them in “The Necessity of Chivalry.” The “marbling of ferocity and meekness,” as LiVecche (Reference LiVecche2019, 7) memorably summarizes this essay, protects the victim-neighbor both against external tyrants and the potential tyrant dormant in the sinful heart of the soldier himself.Footnote ²⁰ It is here, in jus in bello and not jus ad bellum, that Christian conscientious objection comes alive to Lewis: “A man is much more certain that he ought not to murder prisoners or bomb civilians than he ever can be about the justice of a war. It is perhaps here that ‘conscientious objection’ ought to begin. I feel certain that one Christian airman shot for refusing to bomb enemy civilians would be a more effective martyr […] than a hundred Christians in jail for refusing to join the army” (Reference Lewis and Hooper2004a, 251–252).

I said above that “all is fair in love and war” is doubly false. Love limits war, but war imposes major limits on love, too. War qualifies love. Mars qualifies Venus. And this is to be expected given the qualification “insofar as possible” in our understanding of love. Love is the appreciative and responsive commitment to the other's wellbeing insofar as possible and permissible. War seriously limits the possibilities of love. One obvious way war qualifies love is “that it separates you from all you love” (Lewis Reference Lewis and Walmsley2000, 292). But I am thinking of something else.

War and all situations that call for violence compel us to use force and sometimes even lethal force. This sounds circular and tautologous. And it is, but consider what this means. I argue that even in the best scenarios, even when both the reasons and methods are just, the soldier that kills the enemy is primarily motivated by love for others, not for the enemy, if at all. This does not mean that the soldier cannot love the enemy at all. He can and should. It means that he loves the enemy only insofar as he succeeds in appreciating and responsively committing to the enemy's wellbeing despite killing him. The “good kill,” if there is one, is the kill that least violates absolute love. I will try to explain.

The Law of Beneficence: An Order of Loves

Lewis says in The Problem of Pain that the “permanent nature of wood which enables us to use it as a beam also enables us to use it for hitting our neighbour on the head” (Lewis Reference Lewis2002, 24). But, in fact, he believed that what he called “the law of beneficence” sometimes actually compels us to use the wood for the latter purpose, too. The law of beneficence, written into human hearts and the order of things, is based on the absolute general law to do good to everyone, and to so order your loves and responsibilities that when you apply this law in the relative vicissitudes of life, conflicts of interest do not prompt you to love disorderly—that is, neglect higher loves and duties at the expense of lower.

“Every human being,” Lewis says, “has an absolute claim on me for every service I can render them without neglecting other [i.e. higher] duties” (Lewis Reference Lewis and Hooper2004b, 481, emphasis added). “Then come the laws that give certain people a prior claim on your beneficence” (Reference Lewis and Hooper2004b, 699). A hostile enemy's claim might be “inferior to all the other claims involved but not nonexistent” (Reference Lewis and Walmsley2000, 286). “You cannot do simply good to simply Man; you must do this or that good to this or that man. [T]he law of beneficence involves not doing some good to some men at some times. […] And sooner or later it involves helping A by actually doing some degree of violence to B” (Reference Lewis and Walmsley2000, 286). Why is that? Because “when B is up to mischief against A, you must either do nothing […] or you must help one against the other” (286). As already established above, doing nothing is doing something: by omission it allows the mischief to happen. There are risks in both directions.

The language of “higher” and “lower” reveals the hidden presupposition of a hierarchy of loves. For Lewis, the right order of loves means the right order of loyalties. What is this order? And how do we choose? Lewis offers no comprehensive hierarchy, no clear-cut formula, just examples of “rules” which he thinks “have never been doubted” (Reference Lewis and Walmsley2000, 286). These rules or obligations are based on values and intrinsic qualities like justice, patriotism, and even species. For example, special obligation is rendered to “people to whom your beneficence is pledged by a promise (Justice), or who have already benefited you (Gratitude), or who are specially weak and pitiable (Mercy) or fellow-citizens (Patriotism) or relatives (Family Affection). They are all perfectly sound, but the last two must not be allowed to over-ride the others” (Lewis Reference Lewis and Hooper2004b, 699).Footnote ²¹ The feeling of love, even when disordered, is not decisive: “Loving dogs more than children is a misfortune not a sin. Acting on that superior love for dogs—i.e. sacrificing the interests of the human in your household to the animals—is a sin” (Lewis Reference Lewis and Hooper2004b, 788).

The absolute versus relative distinction implicit in much of what has been said is explicitly unpacked in one of Lewis's letters. To underscore its relevance to our subject of enemy love, I have simply substituted the word pain with violence:

Similarly, the just soldier would like it better if no situation which demanded war would rise. If he could choose a situation without such need he would do so. As Chiu puts it: “As violent action is a means to an end, not a good in itself, if the outcome could be achieved without killing a single person, so much the better” (Reference Chiu2019, 19).

Lewis's absolute versus relative distinction anticipates what in contemporary just war theory is called the philosophical doctrine of double effect. It distinguishes the intention of the act from the foreseen but unintended side-effects.Footnote ²² Biggar says that “[s]oldiers should never intend to kill their enemies” (Reference Biggar2013, 14). By “intend” he means to “desire it actively” (Reference Biggar2013, 13) as an end in itself instead of a means to a justified end. To intend an enemy's death is incompatible with loving them, but one may accept it as a foreseen and unintended side-effect of just military action. The principle of double effect is the subject of long-standing controversy.Footnote ²³ I tend to accept the basic distinction, but shun the idiomatic language. Lewis's absolute versus relative distinction might alleviate some of its seeming spuriousness. “I deliberately shot him in the head, but did not intend to kill him” sounds more peculiar or disingenuous (even if technically accurate) than “In these relative circumstances, I did intend to kill him, but I absolutely wish I did not have to.”

And with this, we have arrived at the last hill, which is the steepest. I have been putting off the most difficult question, but it must be faced squarely before we finish. I tried to demonstrate how love for others can motivate violence and in extreme cases even lethal violence. But what about love for the enemy? “How can we both love our enemy-neighbor and kill him?” as LiVecche asks (Reference LiVecche2019, 7). Some Christian pacifists such as Hauerwas are clear: we cannot. On the contrary, “loving enemies means not killing them” (Barringer and Long Reference Barringer and Long2020, 2).

Lewis is more optimistic or at least not as pessimistic about their compatibility. “Even in the very act of fighting,” he says, “I think charity (to the enemy) is not more endangered than in many necessary acts wh. [which] we all admit to be lawful” (Reference Lewis and Hooper2004a, 234). However, since the very act of combat is by definition the attempt to potentially injure or even kill the enemy and, as such, the opposite of contributing to their immediate wellbeing, I submit that for this to make any sense Lewis must here be thinking about some but not all aspects of love. Though war has qualified the practical wellbeing dimension of love, perhaps other more attitudinal, emotional, and other aspects are still possible. In short, Lewis is speaking of the possibility of relative not absolute love. If you do all that is relatively possible, you have done all you can. “Even while we kill and punish,” he thinks, “we must try to feel about the enemy as we feel about ourselves—to wish that he were not bad, to hope that he may, in this world or another, be cured: in fact, to wish his good” (Reference Lewis2001, 120). In cases of capital punishment, it means “being sorry that the man should have done such things [that we should have to kill him], and hoping, if it is anyway possible, that somehow, sometime, somewhere he can be cured” (Reference Lewis2001, 117).

The Enemy's Flourishing: A Response to Biggar and LiVecche

But can it ever be in our enemy's best and real interest for us to kill him? Can we imagine him turning towards us with a dying grimace or groan that basically said: “Thanks, I needed that. Thank you for contributing to my wellbeing”? No, and no. My aim here is not frivolity but dispassionate realism: I cannot think of persuasive or remotely probable real-life examples where our enemy's best and real interest was for us to kill him. But I remain open to being corrected. In every or almost every case the answer must be “No.” If it is “good” let alone “better” for my enemy to die by my hand in battle rather than live another day and be united with his family, it is also “good” for me as his enemy to die by his hand instead of living another day and being united with my family. This conclusion seems absurd to me, so I reject the premise.

It is not entirely clear to me whether Lewis would agree. Perhaps Lewis might think one could love one's enemy by killing them, or they could contribute to your prosperity by killing you. In The Abolition of Man, he chooses death in battle for one's country as the “experimentum crucis” (Reference Lewis2021, 30) that tests the clarity of systems of thought. Roman fathers taught their sons that it was dulce et decorum or “sweet and seemly” to die for their country (Reference Lewis2021, 21). The idea of a “noble” or “glorious” death is not, of course, a uniquely Roman or Christian idea. It is seen in many traditions and texts, such as Sanskrit epic poetry, especially when compared to the alternative of participating in an unfair victory (Chiu Reference Chiu2019, 52, 236). But sweet, how? Glorious, to whom? Is the idea actually true for the dead person, or is it a useful fiction? Can it be accounted for by purely “this world” considerations?

Lewis did say “sometime, somewhere” and “in this world or another.” So perhaps he meant only eternal good not temporal. Does lethal force jeopardize the eternal good of my enemy-neighbor? In some questions, Lewis thought, the eternal perspective makes “[a]ll the difference in the world” (Reference Lewis2001, 119) because “it is immortals we joke with, work with, marry, snub, and exploit” (Reference Lewis and Walmsley2000, 106)—and, we must add, sometimes kill. Again, Lewis is not fully pessimistic: he says war endangers every evil “except dishonour and final perdition” (Reference Lewis and Walmsley2000, 292), echoing the language of “sweet and seemly.” He often speaks of death-by-hangman and death-by-war together: neither, he thinks, decreases our chances of peace with God. If anything, the prospect of dying encourages us to prepare for death (e.g. Lewis Reference Lewis and Walmsley2000, 586).Footnote ²⁴ Screwtape, the demonic character in Lewis's satirical The Screwtape Letters, puts it thus: “Men are killed in places where they knew they might be killed and to which they go, if they are at all of the Enemy's [i.e. God's] party, prepared” (Reference Lewis2013, 23).

However, in many cases, I think Lewis's optimism is unfounded. Even Screwtape acknowledged the conditional “if they are.” Traditional theists—whether Jews, Christians, or Muslims—would assume that many are not, and that many wrongdoers die ill-prepared to meet their Maker. What assurance does anyone have of dying and “finding yourself safely dead and not quite damned” (Lewis Reference Lewis and Hooper2004b, 278), as Lewis hoped would happen to himself?Footnote ²⁵ Biggar says about the death penalty and (I suspect) mutatis mutandis about war, that killing “involves at least two evils—the cutting off of the possibility of a criminal [or soldiering] human being's (earthly) repentance and reformation and reconciliation, as well as his physical death” (Reference Biggar2013, 52–53). Unless God successfully woos every sinner to posthumous repentance, “we must entertain the possibility that ultimate death will be the destiny of some” (Reference Biggar2013, 53). The best a traditional theist, such as Lewis, can confidently say is that hopefully sometimes homicide does not jeopardize posthumous wellbeing. This is not saying much.

And this is where I must part ways with perceptive Christian ethicists like Biggar and LiVecche—and even with C.S. Lewis insofar as LiVecche correctly reads Lewis and I correctly read LiVecche. I think they take it too far and overplay their hand. Biggar believes that “lethal violence can be motivated, not at all by hatred, but by love—even for the enemy” (Reference Biggar2015, 197). I think Biggar is wrong about the last point even according to his own minimalist definition of love as “due respect and care for persons” (197).Footnote ²⁶ LiVecche is also too optimistic and says Lewis shows “how it is possible even to love our enemies, even to love them to death” (Reference LiVecche2019, 1). It would be more correct to say that we can love others to our enemy's death.

LiVecche argues that “when restraining a wrongdoer by forcing him to stop, by deterring him from resuming, and ideally by provoking him to think again and change his aggressive ways, we work toward the promotion of the only possibility for his true flourishing. This belongs to his own good, even if it should cost him his very life. It is the only way to be happy” (Reference LiVecche2019, 9, emphasis added). The key words on which much hinges are wrongdoer and even if it should cost him his very life. The wrongdoer cannot simply be replaced with an enemy combatant, for otherwise, by the logic of war, you as his enemy are also such a “wrongdoer” whose “true flourishing” and “only way to be happy” depends on being stopped by lethal force. Again, this seems nonsensical to me. Enemy combatants may or may not be morally equal,Footnote ²⁷ but this has no bearing on whether their death is good for them.

It is not at all clear to me that even in cases of genuine wrongdoing their death is good for them. The wrongdoing in question must be very grave indeed to justify this belief. What could it be? Please excuse a terribly morbid example, but rules are tested by extremes (another experimentum crucis). Would I be willing to stop, say, a violent rapist in the very act of his crime by lethal force if it were the only way to do so? I hesitate, but I probably would. But would dying be “better” for him than to be allowed to finish his crime and live another day? I cannot fathom it would: not for him, immortal or not. I would of course hope that he could be cured in another world, but (a) I would have no assurance of this and, most importantly, (b) I would not pretend to be motivated by his good. I agree with LiVecche (Reference LiVecche2019, 11; Reference LiVecche2021, 177) that any “interval of hesitation,” as Simone Weil movingly called it (Reference Weil and Miles2000, 174), that might precede my act, any hope-against-hope that the aggressor would stop before I pulled the trigger, is love for him. But killing him is not. That is love for her.

Killing is precisely that part in the enemy-relation that makes our enemy love “relative” not “absolute.” We do not love our enemies to death. Such language obscures its moral ambiguity and is strictly speaking false.Footnote ²⁸ We love our enemies to the extent that killing them least violates absolute love. We may perhaps love them despite killing them, not by killing them. It is precisely their death that remains outside the full expression of love for them. We say in effect: “I will kill you, but I won't torture you needlessly, and I wish you well hereafter.” In absolute terms, this is not saying much, even if it is the overall greatest possible good given the relative circumstances.Footnote ²⁹ In particularly wintry conditions Mars can qualify Venus almost beyond recognition. She is still alive but barely breathes and no longer smiles.
