Charity Lost: The Secularization of the Principle of Double Effect in the Just-War Tradition

CHARITY LOST: TBE SECtJLA'.RIZATfON OF THE PRINCIPLE OF DOUBLE EFFECT IN THE JUST-WAR TRADITION TIMOTHY M. RENICK Georgia State University Atlanta, Georgia 0 N AUGUST 12, 1945, the city of Hiroshima still smoldered, and President Harry Truman addressed the American people : We have used [the atomic bomb] against those who have attacked us without warning at Pearl Harbor, against those who have starved and beaten and executed American prisoners of war, against those who have abandoned all pretense of obeying international laws of warfare. We have used it in order to shorten the agony of war.1 Truman and his military advisers had made a calculation. Japan was preparing for a last-ditch defense of the Japanese Islands. The prospect was ominous, to say the least. The United States had suffered eighty thousand casualties in the taking of the smaller and less protected Okinawa just two months earlier; 120,000 Japanese soldiers had been killed (and only ten-thousand taken prisoner). Strategists estimated that losses, both military and civilian, from a full scale battle for Japan itself would exceed one million. Surely the tens of thousands killed by exploding a bomb over Hiroshima was the lesser evil. Surely this was a proportionate act : fifty thousand lives traded for a million. As Winston Churchill wrote in support of Truman's decision: "To avert a vast, indefinite butchery ... at the cost of a few explosions seemed, after all our toils and perils, a miracle of deliverance." 2 1 Michael Walzer, lust and Unjust Wars (New York: Basic Books, 1979), p.164. 2 Ibid., pp. 266-267. 441 442 TIMOTHY M. RENICK From an ethical perspective, however, the act was anything but a deliverance. I am not alone in this assessment. Advocates of the just-war tradition including Elizabeth Anscombe, Paul Ramsey, George Kennan, John Langan, and Michael Walzer have condemned the bombing of Hiroshima by means of a shared just-war argument.8 The argument goes as follows, and it is a good one. In times of war, many actions are likely to have both good and evil effects. One destroys an enemy's munitions factory (good effect) but kills an innocent child in the process (evil effect). The jus in bello of the just-war tradition, however, stipulates that an action which has a " double effect " is permissible if and only if: ( 1) it is discriminate (i.e., the actor aims only at the good effect and does not intend the evil effect, nor is the evil effect a means to the end, however good); and (2) it is proportionate (i.e., the good created by the act outweighs the bad) .4 Now, the argument continues, Truman's decision to bomb Hiroshima failed the first criterion. It was not a discriminate act because the evil effect (the killing of tens of thousands of Japanese civilians) was not unintended. In fact, the evil was the very means to the good end. Although Truman himself claimed to have selected Hiroshima as a target because it was "a war s See, for example, G. E. M. Anscombe, "Mr. Truman's Decision," in Ethics, Religion and Politics (Minneapolis, Minn.: University of Minnesota, 1981); M. Walzer "Supreme Emergency," in Just and Unjust Wars; and John Langan, "The American Hierarchy and Nuclear Weapons," Theological Studies 43 (1982) : 447-467. ' I utilize here a helpful shorthand version of the principle of double effect introduced by Paul Ramsey in War and the Christian Conscience (Durham, North Carolina: Duke, 1961). More frequently, the principle is rendered by means of four criteria: It is permissible to perform an act likely to have evil consequences if and only if (I) the act is good in itself or at least indifferent; (2) the direct effect is morally justified; (3) the actor aims only at the acceptable effect and does not intend the evil effect, nor is the evil effect a means to the end, however good ; and (4) there is in the good effect a proportionately grave reason for permitting the evil effect. The shortened version of the theory captures all components essential to my discussion and enhances clarity. I thus will make use of it throughout this essay. CHARITY AND...
