What about our much championed freedom of religious belief? It is no different from our freedoms of journalistic and biological belief-and anyone who believes that the media are perpetrating a great fire conspiracy, or that molecular biology is just a theory that may prove totally wrong, has merely exercised his freedom to be thought a fool. Religious unreason should acquire an even greater stigma in our discourse, given that it remains among the principal causes of armed conflict in our world. Before you can get to the end of this paragraph, another person will probably die because of what someone else believes about God. Perhaps it is time we demanded that our fellow human beings had better reasons for maintaining their religious differences, if such reasons even exist.

  We must begin speaking freely about what is really in these holy books of ours, beyond the timid heterodoxies of modernity-the gay and lesbian ministers, the Muslim clerics who have lost their taste for public amputations, or the Sunday churchgoers who have never read their Bibles quite through. A close study of these books, and of history, demonstrates that there is no act of cruelty so appalling that it cannot be justified, or even mandated, by recourse to their pages. It is only by the most acrobatic avoidance of passages whose canonicity has never been in doubt that we can escape murdering one another outright for the glory of God. Bertrand Russell had it right when he made the following observation:

  The Spaniards in Mexico and Peru used to baptize Indian infants and then immediately dash their brains out: by this means they secured these infants went to Heaven. No orthodox Christian can find any logical reason for condemning their action, although all nowadays do so. In countless ways the doctrine of personal immortality in its Christian form has had disastrous effects upon morals....35

  It is true that there are millions of people whose faith moves them to perform extraordinary acts of self-sacrifice for the benefit of others. The help rendered to the poor by Christian missionaries in the developing world demonstrates that religious ideas can lead to actions that are both beautiful and necessary. But there are far better reasons for self-sacrifice than those that religion provides. The fact that faith has motivated many people to do good things does not suggest that faith is itself a necessary (or even a good) motivation for goodness. It can be quite possible, even reasonable, to risk one's life to save others without believing any incredible ideas about the nature of the universe.

  By contrast, the most monstrous crimes against humanity have invariably been inspired by unjustified belief. This is nearly a truism. Genocidal projects tend not to reflect the rationality of their perpetrators simply because there are no good reasons to kill peaceful people indiscriminately. Even where such crimes have been secular, they have required the egregious credulity of entire societies to be brought off. Consider the millions of people who were killed by Stalin and Mao: although these tyrants paid lip service to rationality, communism was little more than; a political religion.36 At the heart of its apparatus of repression and terror lurked a rigid ideology, to which generations of men and women were sacrificed. Even though their beliefs did not reach beyond this world, they were both cultic and irrational. To cite only one example, the dogmatic embrace of Lysenko's "socialist" biology-as distinguished from the "capitalist" biology of Mendel and Darwin-helped pave the way for tens of millions of deaths from famine in the Soviet Union and China in the first part of the twentieth century.

  In the next chapter we will examine two of the darkest episodes in the history of faith: the Inquisition and the Holocaust. I have chosen the former as a case study because there is no other instance in which so many ordinary men and women have been so deranged by their beliefs about God; nowhere else has the subversion of reason been so complete or its consequences so terrible. The Holocaust is relevant here because it is generally considered to have been an entirely secular phenomenon. It was not. The anti-Semitism that built the crematoria brick by brick-and that still thrives today-comes to us by way of Christian theology. Knowingly or not, the Nazis were agents of religion.

  In the Shadow of God

  Without warning you are seized and brought before a judge. Did you create a thunderstorm and destroy the village harvest? Did you kill your neighbor with the evil eye? Do you doubt that Christ is bodily present in the Eucharist? You will soon learn that questions of this sort admit of no exculpatory reply.

  You are not told the names of your accusers. But their identities are of little account, for even if, at this late hour, they were to recant their charges against you, they would merely be punished as false witnesses, while their original accusations would retain their full weight as evidence of your guilt. The machinery of justice has been so well oiled by faith that it can no longer be influenced.

  But you have a choice, of sorts: you can concede your guilt and name your accomplices. Yes, you must have had accomplices. No confession will be accepted unless other men and women can be implicated in your crimes. Perhaps you and three acquaintances of your choosing did change into hares and consort with the devil himself. The sight of iron boots designed to crush your feet seems to refresh your memory. Yes, Friedrich, Arthur, and Otto are sorcerers too. Their wives? Witches all.

  You now face punishment proportionate to the severity of your crimes: flogging, a pilgrimage on foot to the Holy Land, forfeiture of property, or, more likely, a period of long imprisonment, probably for life. Your "accomplices" will soon be rounded up for torture.

  Or you can maintain your innocence, which is almost certainly the truth (after all, it is the rare person who can create a thunderstorm).

  In response, your jailers will be happy to lead you to the furthest reaches of human suffering, before burning you at the stake. You may be imprisoned in total darkness for months or years at a time, repeatedly beaten and starved, or stretched upon the rack. Thumbscrews may be applied, or toe screws, or a pear-shaped vise may be inserted into your mouth, vagina, or anus, and forced open until your misery admits of no possible increase. You may be hoisted to the ceiling on a strappado (with your arms bound behind your back and attached to a pulley, and weights tied to your feet), dislocating your shoulders. To this torment squassation might be added, which, being often sufficient to cause your death, may yet spare you the agony of the stake.1 If you are unlucky enough to be in Spain, where judicial torture has achieved a transcendent level of cruelty, you may be placed in the "Spanish chair": a throne of iron, complete with iron stocks to secure your neck and limbs. In the interest of saving your soul, a coal brazier will be placed beneath your bare feet, slowly roasting them. Because the stain of heresy runs deep, your flesh will be continually larded with fat to keep it from burning too quickly. Or you may be bound to a bench, with a cauldron filled with mice placed upside-down upon your bare abdomen. With the requisite application of heat to the iron, the mice will begin to burrow into your belly in search of an exit.2

  Should you, while in extremis, admit to your torturers that you are indeed a heretic, a sorcerer, or a witch, you will be made to confirm your story before a judge-and any attempt to recant, to claim that your confession has been coerced through torture, will deliver you either to your tormentors once again or directly to the stake. If, once condemned, you repent of your sins, these compassionate and learned men-whose concern for the fate of your eternal soul really knows no bounds-will do you the kindness of strangling you before lighting your pyre.3

  The medieval church was quick to observe that the Good Book was good enough to suggest a variety of means for eradicating heresy, ranging from a communal volley of stones to cremation while alive.4 A literal reading of the Old Testament not only permits but requires heretics to be put to death. As it turns out, it was never difficult to find a mob willing to perform this holy office, and to do so purely on the authority of the Church-since it was still a capital offense to possess a Bible in any of the vernacular languages of Europe.5 In fact, scripture was not to become generally accessible to the common man until the sixteenth century. As we noted earlier, Deuteronomy was the
preeminent text in every inquisitor's canon, for it explicitly enjoins the faithful to murder anyone in their midst, even members of their own families, who profess a sympathy for foreign gods. Showing a genius for totalitarianism that few mortals have ever fully implemented, the author of this document demands that anyone too squeamish to take part in such religious killing must be killed as well (Deuteronomy 17:12-13). 6 Anyone who imagines that no justification for the Inquisition can be found in scripture need only consult the Bible to have his view of the matter clarified:

  If you hear that in one of the towns which Yahweh your God has given you for a home, there are men, scoundrels from your own stock, who have led their fellow-citizens astray, saying, "Let us go and serve other gods," hitherto unknown to you, it is your duty to look into the matter, examine it, and inquire most carefully. If it is proved and confirmed that such a hateful thing has taken place among you, you must put the inhabitants of that town to the sword; you must lay it under the curse of destruction-the town and everything in it. You must pile up all its loot in the public square and burn the town and all its loot, offering it all to Yahweh your God. It is to be a ruin for all time and never rebuilt. (Deuteronomy 13:12-16).

  For obvious reasons, the church tended to ignore the final edict: the destruction of heretic property.

  In addition to demanding that we fulfill every "jot" and "tittle" of Old Testament law, Jesus seems to have suggested, in John 15:6, further refinements to the practice of killing heretics and unbelievers: "If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned." Whether we want to interpret Jesus metaphorically is, of course, our business. The problem with scripture, however, is that many of its possible interpretations (including most of the literal ones) can be used to justify atrocities in defense of the faith.

  The Holy Inquisition formally began in 1184 under Pope Lucius III, to crush the popular movement of Catharism. The Cathars (from the Greek katharoi, "the pure ones") had fashioned their own brand of Manicheanism (Mani himself was flayed alive at the behest of Zoroastrian priests in 276 CE), which held that the material world had been created by Satan and was therefore inherently evil. The Cathars were divided by a schism of their own and within each of their sects by the distinction between the renunciate perfecti and the lay credentes ("the believers") who revered them. The perfecti ate no meat, eggs, cheese, or fat, fasted for days at a time, maintained strict celibacy, and abjured all personal wealth. The life of the perfecti was so austere that most credentes only joined their ranks once they were safely on their deathbeds, so that, having lived as they pleased, they might yet go to God in holiness. Saint Bernard, who had tried in vain to combat this austere doctrine with that of the church, noted the reasons for his failure: "As to [the Cathars'] conversation, nothing can be less reprehensible ... and what they speak, they prove by deeds. As for the morals of the heretic, he cheats no one, he oppresses no one, he strikes no one; his cheeks are pale with fasting, ... his hands labor for his livelihood."8

  There seems, in fact, to have been nothing wrong with these people apart from their attachment to certain unorthodox beliefs about the creation of the world. But heresy is heresy. Any person who believes that the Bible contains the infallible word of God will understand why these people had to be put to death.

  The Inquisition took rather genteel steps at first (the use of torture to extract confessions was not "officially" sanctioned until 1215, at the Fourth Lateran Council), but two developments conspired to lengthen its strides. The first came in 1199 when Pope Innocent III decreed that all property belonging to a convicted heretic would be forfeited to the church; the church then shared it both with local officials and with the victim's accusers, as a reward for their candor. The second was the rise of the Dominican order.9 Saint Dominic himself, displaying the conviction of every good Catholic of the day, announced to the Cathars, "For many years I have exhorted you in vain, with gentleness, preaching, praying, weeping. But according to the proverb of my country, 'where blessing can accomplish nothing, blows may avail.' We shall rouse against you princes and prelates, who, alas, will arm nations and kingdoms against this land...."10 It would appear that sainthood comes in a variety of flavors. With the founding of Dominic's holy order of mendicant friars, the Inquisition was ready to begin its work in earnest. It is important to remember, lest the general barbarity of time inure us to the horror of these historical accounts, that the perpetrators of the Inquisition-the torturers, informers, and those who commanded their actions-were ecclesiastics of one rank or another. They were men of God-popes, bishops, friars, and priests. They were men who had devoted their lives, in word if not in deed, to Christ as we find him in the New Testament, healing the sick and challenging those without sin to cast the first stone:

  In 1234, the canonization of Saint Dominic was finally proclaimed in Toulouse, and Bishop Raymond du Fauga was washing his hands in preparation for dinner when he heard the rumor that a fever-ridden old woman in a nearby house was about to undergo the Cathar ritual. The bishop hurried to her bedside and managed to convince her that he was a friend, then interrogated her on her beliefs, then denounced her as a heretic. He called on her to recant. She refused. The bishop thereupon had her bed carried out into a field, and there she was burned. "And after the bishop and the friars and their companions had seen the business completed," Brother Guillaume wrote, "they returned to the refectory and, giving thanks to God and the Blessed Dominic, ate with rejoicing what had been prepared for them."11

  The question of how the church managed to transform Jesus' principal message of loving one's neighbor and turning the other cheek into a doctrine of murder and rapine seems to promise a harrowing mystery; but it is no mystery at all. Apart from the Bible's heterogeneity and outright self-contradiction, allowing it to justify diverse and irreconcilable aims,12 the culprit is clearly the doctrine of faith itself. Whenever a man imagines that he need only believe the truth of a proposition, without evidence-that unbelievers will go to hell, that Jews drink the blood of infants-he becomes capable of anything.

  The practice for which the Inquisition is duly infamous, and the innovation that secured it a steady stream of both suspects and guilty verdicts, was its use of torture to extract confessions from the accused, to force witnesses to testify, and to persuade a confessing heretic to name those with whom he had collaborated in sin. The justification for this behavior came straight from Saint Augustine, who reasoned that if torture was appropriate for those who broke the laws of men, it was even more fitting for those who broke the laws of God.13 As practiced by medieval Christians, judicial torture was merely a final, mad inflection of their faith. That anyone imagined that facts were being elicited by such a lunatic procedure seems a miracle in itself. As Voltaire wrote in 1764, "There is something divine here, for it is incomprehensible that men should have patiently borne this yoke."14

  A contemporaneous account of the Spanish auto-da-fe (the public spectacle at which heretics were sentenced and often burned) will serve to complete our picture. The Spanish Inquisition did not cease its persecution of heretics until 1834 (the last auto-da-fe took place in Mexico in 1850), about the time Charles Darwin set sail on the

  Beagle and Michael Faraday discovered the relationship between electricity and magnetism.

  The condemned are then immediately carried to the Riberia, the place of execution, where there are as many stakes set up as there are prisoners to be burnt. The negative and relapsed being first strangled and then burnt; the professed mount their stakes by a ladder, and the Jesuits, after several repeated exhortations to be reconciled to the church, consign them to eternal destruction, and then leave them to the fiend, who they tell them stands at their elbow to carry them into torments. On this a great shout is raised, and the cry is, "Let the dogs' beards be made"; which is done by thrusting flaming bunches of furze, fastened to long poles, against their beards, till their faces are burnt black, the sur
rounding populace rending the air with the loudest acclamations of joy. At last fire is set to the furze at the bottom of the stake, over which the victims are chained, so high that the flame seldom reaches higher than the seat they sit on, and thus they are rather roasted than burnt. Although there cannot be a more lamentable spectacle and the sufferers continually cry out as long as they are able, "Pity for the love of God!" yet it is beheld by persons of all ages and both sexes with transports of joy and satisfaction.15

  And while Protestant reformers broke with Rome on a variety of counts, their treatment of their fellow human beings was no less disgraceful. Public executions were more popular than ever: heretics were still reduced to ash, scholars were tortured and killed for impertinent displays of reason, and fornicators were murdered without a qualm.16 The basic lesson to be drawn from all this was summed up nicely by Will Durant: "Intolerance is the natural concomitant of strong faith; tolerance grows only when faith loses certainty; certainty is murderous."17
