In one of his letters Thomas Jefferson remarked that in matters of religion “the maxim of civil government” should be reversed and we should rather say, “Divided we stand, united, we fall.” In this remark Jefferson was setting forth with classic terseness an idea that has come to be regarded as essentially American: the separation of Church and State. This idea was not entirely new; it had some precedents in the writings of Spinoza, Locke, and the philosophers of the European Enlightenment. It was in the United States, however, that the principle was first given the force of law and gradually, in the course of two centuries, became a reality.
If the idea that religion and politics should be separated is relatively new, dating back a mere three hundred years, the idea that they are distinct dates back almost to the beginnings of Christianity. Christians are enjoined in their Scriptures to “render … unto Caesar the things which are Caesar’s and unto God the things which are God’s.” While opinions have differed as to the real meaning of this phrase, it has generally been interpreted as legitimizing a situation in which two institutions exist side by side, each with its own laws and chain of authority—one concerned with religion, called the Church, the other concerned with politics, called the State. And since they are two, they may be joined or separated, subordinate or independent, and conflicts may arise between them over questions of demarcation and jurisdiction.
This formulation of the problems posed by the relations between religion and politics, and the possible solutions to those problems, arise from Christian, not universal, principles and experience. There are other religious traditions in which religion and politics are differently perceived, and in which, therefore, the problems and the possible solutions are radically different from those we know in the West. Most of these traditions, despite their often very high level of sophistication and achievement, remained or became local—limited to one region or one culture or one people. There is one, however, that in its worldwide distribution, its continuing vitality, its universalist aspirations, can be compared to Christianity, and that is Islam.
Islam is one of the world’s great religions. Let me be explicit about what I, as a historian of Islam who is not a Muslim, mean by that. Islam has brought comfort and peace of mind to countless millions of men and women. It has given dignity and meaning to drab and impoverished lives. It has taught people of different races to live in brotherhood and people of different creeds to live side by side in reasonable tolerance. It inspired a great civilization in which others besides Muslims lived creative and useful lives and which, by its achievement, enriched the whole world. But Islam, like other religions, has also known periods when it inspired in some of its followers a mood of hatred and violence. It is our misfortune that part, though by no means all or even most, of the Muslim world is now going through such a period, and that much, though again not all, of that hatred is directed against us.
We should not exaggerate the dimensions of the problem. The Muslim world is far from unanimous in its rejection of the West, nor have the Muslim regions of the Third World been the most passionate and the most extreme in their hostility. There are still significant numbers, in some quarters perhaps a majority, of Muslims with whom we share certain basic cultural and moral, social and political, beliefs and aspirations; there is still an imposing Western presence—cultural, economic, diplomatic—in Muslim lands, some of which are Western allies. Certainly nowhere in the Muslim world, in the Middle East or elsewhere, has American policy suffered disasters or encountered problems comparable to those in Southeast Asia or Central America. There is no Cuba, no Vietnam, in the Muslim world, and no place where American forces are involved as combatants or even as “advisers.” But there is a Libya, an Iran, and a Lebanon, and a surge of hatred that distresses, alarms, and above all baffles Americans.
At times this hatred goes beyond hostility to specific interests or actions or policies or even countries and becomes a rejection of Western civilization as such, not only what it does but what it is, and the principles and values that it practices and professes. These are indeed seen as innately evil, and those who promote or accept them as the “enemies of God.”
This phrase, which recurs so frequently in the language of the Iranian leadership, in both their judicial proceedings and their political pronouncements, must seem very strange to the modern outsider, whether religious or secular. The idea that God has enemies, and needs human help in order to identify and dispose of them, is a little difficult to assimilate. It is not, however, all that alien. The concept of the enemies of God is familiar in preclassical and classical antiquity, and in both the Old and New Testaments, as well as in the Koran. A particularly relevant version of the idea occurs in the dualist religions of ancient Iran, whose cosmogony assumed not one but two supreme powers. The Zoroastrian devil, unlike the Christian or Muslim or Jewish devil, is not one of God’s creatures performing some of God’s more mysterious tasks but an independent power, a supreme force of evil engaged in a cosmic struggle against God. This belief influenced a number of Christian, Muslim, and Jewish sects, through Manichaeism and other routes. The almost forgotten religion of the Manichees has given its name to the perception of problems as a stark and simple conflict between matching forces of pure good and pure evil.
The Koran is of course strictly monotheistic, and recognizes one God, one universal power only. There is a struggle in human hearts between good and evil, between God’s commandments and the tempter, but this is seen as a struggle ordained by God, with its outcome preordained by God, serving as a test of mankind, and not, as in some of the old dualist religions, a struggle in which mankind has a crucial part to play in bringing about the victory of good over evil. Despite this monotheism, Islam, like Judaism and Christianity, was at various stages influenced, especially in Iran, by the dualist idea of a cosmic clash of good and evil, light and darkness, order and chaos, truth and falsehood, God and the Adversary, variously known as devil, Iblis, Satan, and by other names.
In Islam the struggle of good and evil very soon acquired political and even military dimensions. Muhammad, it will be recalled, was not only a prophet and a teacher, like the founders of other religions; he was also the head of a polity and of a community, a ruler and a soldier. Hence his struggle involved a state and its armed forces. If the fighters in the war for Islam, the holy war “in the path of God,” are fighting for God, it follows that their opponents are fighting against God. And since God is in principle the sovereign, the supreme head of the Islamic state—and the Prophet and, after the Prophet, the caliphs are his vicegerents—then God as sovereign commands the army. The army is God’s army and the enemy is God’s enemy. The duty of God’s soldiers is to dispatch God’s enemies as quickly as possible to the place where God will chastise them—that is to say, the afterlife.
Clearly related to this is the basic division of mankind as perceived in Islam. Most, probably all, human societies have a way of distinguishing between themselves and others: insider and outsider, in-group and out-group, kinsman or neighbor and foreigner. These definitions not only define the outsider but also, and perhaps more particularly, help to define and illustrate our perception of ourselves.
In the classical Islamic view, to which many Muslims are beginning to return, the world and all mankind are divided into two: the House of Islam, where the Muslim law and faith prevail, and the rest, known as the House of Unbelief or the House of War, which it is the duty of Muslims ultimately to bring to Islam. But the greater part of the world is still outside Islam, and even inside the Islamic lands, according to the view of the Muslim radicals, the faith of Islam has been undermined and the law of Islam has been abrogated. The obligation of holy war therefore begins at home and continues abroad, against the same infidel enemy.
Like every other civilization known to human history, the Muslim world in its heyday saw itself as the center of truth and enlightenment, surrounded by infidel barbarians whom it would in due course enlighten and civilize. But between the different groups of barbarians there was a crucial difference. The barbarians to the east and the south were polytheists and idolaters, offering no serious threat and no competition at all to Islam. In the north and west, in contrast, Muslims from an early date recognized a genuine rival—a competing world religion, a distinctive civilization inspired by that religion, and an empire that, though much smaller than theirs, was no less ambitious in its claims and aspirations. This was the entity known to itself and others as Christendom, a term that was long almost identical with Europe.
The struggle between these rival systems has now lasted for some fourteen centuries. It began with the advent of Islam, in the seventh century, and has continued virtually to the present day. It has consisted of a long series of attacks and counterattacks, jihads and crusades, conquests and reconquests. For the first thousand years Islam was advancing, Christendom in retreat and under threat. The new faith conquered the old Christian lands of the Levant and North Africa, and invaded Europe, ruling for a while in Sicily, Spain, Portugal, and even parts of France. The attempt by the Crusaders to recover the lost lands of Christendom in the east was held and thrown back, and even the Muslims’ loss of southwestern Europe to the Reconquista was amply compensated by the Islamic advance into southeastern Europe, which twice reached as far as Vienna. For the past three hundred years, since the failure of the second Turkish siege of Vienna in 1683 and the rise of the European colonial empires in Asia and Africa, Islam has been on the defensive, and the Christian and post-Christian civilization of Europe and her daughters has brought the whole world, including Islam, within its orbit.
