Toleration is a policy or attitude toward something that is not approved and yet is not actively rejected. The word comes from the Latin tolerare (to bear or endure), suggesting a root meaning of putting up with something. There is no single and widely accepted definition of the term, and it is hardly an exaggeration to say that every author uses it in his or her own way. Therefore it may be best to understand the many uses of the word in terms of family resemblances.

It should be clear that each of the languages that uses a variant of the Latin term (German, Toleranz; Dutch, tolerantie; French, tolérance; Spanish, tolerancia; Italian, tolleranza; etc.) adds its own slightly different connotations to the word, based on historical experiences. Languages that do not derive the word from Latin have synonyms, each with some overlap and some difference in usage.

Throughout much of the history of the concept, toleration referred largely to a policy or attitude toward different religions. Intolerance could mean burning at the stake of heretics or apostates and forced conversions of adherents to different religions, and tolerance could mean anything short of that. By the late twentieth century, demands for toleration could also refer to other disputed behaviors such as sexual orientations, clothing and dress, drug use, vegetarianism versus meat-eating, and more (although religion was often not far behind these disputes). Ethnic and cultural behaviors and language usage could be the subject of tolerance and intolerance as well. In medicine, toleration refers to an organism's capacity to absorb or endure something without untoward consequences.

Conceptual Nuances

Most uses of the word understand it as referring to a middle ground on a spectrum between rejection, intolerance, hate, and persecution on one end, and acceptance, approval, love, and respect on the other. They distinguish it from indifference because it only comes into play when something is disliked or disapproved and matters.

Who is doing the tolerating, who or what is being tolerated, and exactly what such toleration entails can vary enormously. Individuals can be said to tolerate their own personal foibles, not to tolerate fools, or to tolerate whole groups. Groups can be said to tolerate individuals within or without, or other groups. States and other political authorities can be said to tolerate individuals, groups, or other states. That which is tolerated can range from the very existence to the appearance, ideas, or activities of the tolerated entity. Toleration can range from providing only limited encouragement, to doing nothing, to applying limited sanctions short of persecution.

Some authors have tried to distinguish "toleration" from "tolerance," with the former referring to official policies and the latter to a personal attribute, but ordinary language does not seem to distinguish the two. For example, we can say that the behavior of tolerant persons shows that they tolerate others, or that all we are asking for from another person is toleration. We can also say that a government policy reflects tolerance of some activity.

Some authors have thought that toleration is only a second-best, half-way measure, and that we ought to go beyond toleration to embrace and respect others. This is certainly the right thing to do where whatever is being tolerated actually deserves to be embraced. But one can wonder if all human beings really are always doing things that deserve respect. What would the world be like if all people and all of their activities were worthy of embrace? Certainly unlike anything we have seen so far. Then, perhaps, there would be no need for a concept like toleration. But until that moment arrives, this is the term for the response to things that merit neither active persecution nor full acceptance.

Toleration may look weak and thin from the perspective of a possible acceptance and embrace, but it can look very good from the perspective of someone who is undergoing persecution. Many a victim of intolerance would just like to be left alone, and that is one of the modes of toleration. One of the paradoxes of toleration is that if one is tolerant of everything, then one is also tolerant of the intolerant. This may mean complicity with persecution, or at least failure to prevent it.

Related Concepts

A large vocabulary of related concepts has been used to define and promote toleration. If, as mentioned above, religion created many of the disputes that lead to persecution, it also produced many concepts that can lead toward toleration. Irenicism (the seeking of peace), the pursuit of concord, comprehension, latitudinarianism, and basic agreement on fundamentals have been policies of many theologians and churchmen. Where these policies recognize that we may never approve of everything the other thinks or does, they promote toleration. Where they imply that someday we will all agree, they go beyond it.

Other terms that have both religious and secular meanings are relevant. Mercy and charity may inspire one to tolerate. Patience is close to the root meaning of the Latin word, helping one endure what one disapproves. Humility, modesty, and skepticism about one's own knowledge of what is right may incline one to tolerate others even when one disagrees with them. Indulgence can mean allowing something that one could prevent. Compromise may mean conceding some points in order to gain others, tolerating the loss of the conceded points.

High-minded philosophical principles can lead toward toleration. Belief in the autonomy and independence of other people can justify leaving them alone even when one does not like what they are doing. Principles of impartiality and neutrality may make a state stay out of religious or other quarrels. Of course, not just any principle will do: most persecution is justified by principle as well.

Toleration has not always been the result of principle. It can come about for purely practical reasons because of exhaustion, impotence, or impasse. It can be the result of politique calculation that hostility does not pay. Swiss physician and theologian Thomas Erastus (15241583) gave his name to Erastianism, a term for state supremacy and policies that enforce toleration in order to maintain political stability and prevent religious fighting. Gag orders and decrees prohibiting further debate have often been used to silence contending parties in the hopes of reaching a modicum of mutual toleration.

Liberty of conscience and freedom of religion are policies that sometimes overlap with toleration and sometimes go beyond it. Liberty of conscience usually means that everyone may think what they like, and no one will inquire into what they think. But this is compatible with suppressing public expression of what one thinks. On the one hand, this may be better than regimes in which "thought police" are constantly monitoring people's ideas; on the other, it is not as free as forms of toleration that permit expression. Freedom of religion often means that one can choose among two or more established religions, but it sometimes also implies that one must choose one of the available religions. It may not tolerate rejection of all religion.


In modern times and in liberal ideology, toleration has a positive valence, associated with open-mindedness and egalitarianism. It can be a valued character trait or a beneficial attribute of a group or state.

But toleration has also been considered a negative trait or attribute. It can be associated with laziness, carelessness, and slacking. While many moderns do not consider it lazy or careless to tolerate other religions, we can capture some of the force that this charge once had if we consider that doing nothing about cruelty or murder could be characterized as tolerating it. Then the tolerators would be tolerating something they should not, perhaps out of cowardice or carelessness.

Another negative valence of toleration can be found in the Marxist tradition, where tolerating something can be considered part of an oppressive regime. "Repressive tolerance" can include tolerating evil and oppressive people or activities. It can also mean tolerating a protesting group and thus depriving it of the importance it would have if it were taken seriously. In effect, this theory holds that in conditions of class inequality, both tolerance and intolerance are repressive.

Other modern groups have considered toleration condescending and ultimately affirmative of conditions of injustice. For example, T. S. Eliot (18881965) wrote that in the conditions of modern secularism "The Christian does not want to be tolerated" (Cranston, p. 101); rather, she wants to be respected. Similarly, spokespeople for ethnic groups, women, gays, and others have objected that simply being in a position of having to be tolerated is already unfair, reflecting power inequalities.

Perhaps because of its middle-way position, toleration is rarely likely to be stable over a long period. Rather, persons or states can become more or less tolerant or more or less tolerated as time goes by and opinions or conditions change. Since intolerance is often a response to a perceived threat, when the perception of threat increases or decreases, toleration may become less or more of an option. Individuals or groups that were once persecuted out of fear but are now perceived as harmless can become tolerated and eventually embraced. Vice versa, if people who were once considered innocuous become perceived as more of a threat, intolerance of them may increase.

Toleration in the Ancient World

Cyrus the Great of Persia (r. c. 558529 b.c.e.) is a key figure at the foundation of two traditions of toleration. He is praised in the Hebrew Bible for allowing the Jews to return to Jerusalem after Babylonian captivity. And Xenophon (c. 431c. 352 b.c.e.) lauded him in The Education of Cyrus (after 394 b.c.e.) for his policy of religious toleration, placing him in the Greek tradition. Scholars have speculated that his toleration of Medes, Hyrcanians, and other religious and ethnic groups was largely an imperial political strategy. He needed to draw on the manpower of conquered kingdoms and knew it would be easier to defeat kings whose peoples believed they could thrive under his rule.

Aspects of Buddhist religious thought, which originated in India, also justified peacefulness and toleration. Ashoka (r. c. 273232 b.c.e.), the last emperor of the Mauryan dynasty in India, renounced war and promoted Buddhism while remaining tolerant of other religions.

Throughout much of history, the ancient Chinese were tolerant of a variety of religions ranging from Confucianism to Buddhism and Taoism to animism. Manichaeans and Jews thrived at times. Scholars have speculated that it was precisely because they were tolerated and not persecuted that Jews in ancient China seem to have shed their identity and blended into the rest of the population.

The Koran contains passages about living in peace with peoples of other religions, especially "peoples of the book" (Jews and Christians). Therefore, Islamic cultures such as medieval Spain tolerated flourishing Christian and Jewish communities in what was known as convivencia, or living together in peace. The Ottoman Empire developed regimes of toleration of those religions that included the "millet" system, in which each religion had its own legal system and paid its own tax rate, even though only Muslims could hold higher offices.

The ancient Romans were generally tolerant of the existence of many cults because of polytheism, which implied that every hearth, city, and people could have its own gods. When they became an imperial power, they tolerated any religion that would also show signs of respect for Roman deities. They conceived of the Jewish War not as wars against that religion but against a rebellious subject people. Christians were persecuted for their refusal to take part in the imperial cult and for their disrespect for Roman rule, not merely for their religion.

The Rise of Christian Persecution

Throughout world history, local practices of toleration have been interspersed with pogroms and persecution. Sometimes practices of toleration have come before ideas about it, and sometimes ideas have come before practices. Wherever toleration is practiced as a norm, there is not much need to think or write about it. By far the most elaborate discussion of the issue took place in the Christian West in the period from 1500 to 1800, precisely because a great deal of persecution was going on. To fully understand it, we must go back to the origins of Christian persecution.

The situation in the Roman Empire changed when the emperor Constantine (r. 306337) legalized Christianity in 313 and promoted it as the public religion. Now it was implicated in state power and had to decide whether to tolerate or persecute others. In the following millennium there were wars against Muslims and persecution of pagans and Jews, as well as contentions within Christianity. With respect to the latter, one could justify intolerance if the people one disagreed with could be labeled as heretics or blasphemers.

The word heresy originally meant "choice," as in a choice of beliefs or sects, with no negative connotations. But various passages in the New Testament used it to mean sinful divisiveness. Early church fathers such as St. Irenaeus (c. 120 to 140c. 200 to 203), Tertullian (c. 155 or 160after 220), and Eusebius of Caesaria (c. 260c. 339) refuted the chief early heresies. In 325 Constantine convened the Council of Nicaea to settle church doctrine and then issued an edict banning heresies. In 385 a Spanish bishop, Priscillian (c. 340385), became the first person to be executed for heresy.

St. Augustine of Hippo (354430) was the most influential theorist of persecution. After belonging to the Manichaean heresy in his youth, he joined the Catholic Church in 387 and eventually became a bishop. Facing Manichaean, Pelagian, and Donatist heresies, at first he advocated peaceful methods but by about 400 he began to endorse coercion. He interpreted the parable of the tares (Matt. 13:2430) and the parable of the feast (Luke 14:2123) to justify coercion of heretics. The latter was a particularly long stretch, because the parable merely has a rich man prepare a banquet and send his servant out into the streets to find people and "compel them to come in." Later, both Catholics and Protestants justified forced conversions on the basis of this invitation to a feast.

Further developments in the justification of persecution include the definitions of heresy in Gratian of Bologna's (d. before 1159) Decretum (c. 1140) and many further decrees. The persecution of heretics became the object of armed warfare in the bloody Albigensian Crusade (12091229). In 1233 Pope Gregory IX (ruled 12271241) assigned the persecution of heresy to the Dominican order, establishing the Inquisition.

Medieval voices for tolerance.

However, not everyone went along with the violent treatment of religious difference. The Dialogue of a Philosopher with a Jew and a Christian of Peter Abelard (1079?1144) demonstrated that the pursuit of knowledge could not be detached from the inclusion of diverse standpoints. John of Salisbury (c. 11151180) and Marsilius of Padua (c. 1280c. 1343) combined defenses of personal liberty with functionalist accounts of the organic unity of the political community to maintain that the health of the body politic requires freedom of thought, speech, and even action. John Wycliffe (13301384) developed a theory of toleration that derived from his theology of grace and his political theory of the king's responsibility to protect the welfare of both the graced and the ungraced.

Medieval times also included voices for toleration from the disempowered. Menachem Ha-Me'iri (12491316) developed a uniquely Jewish theory of toleration to justify cooperation with gentiles. Christine de Pisan (13641430) stressed the interdependence of the various parts of the body politic to justify tolerant treatment of differences of gender, class, and nationality.

In the late medieval or early Renaissance period, Nicholas of Cusa's The Peace of the Faith (1453) recognized that mankind was inherently and inescapably diverse in language, culture, and politics. If there will always be different customs and rites, toleration is justified because persecution is futile. Giovanni Pico della Mirandola (14631494) and others from this period also developed toleration for non-Christians from their interests in the Jewish Kabbalah and pagan philosophy.

Early Modern Period

The Protestant Reformation created the most serious challenge to toleration in early modern Europe. Martin Luther (14831546), John Calvin (15091564), and Huldrych Zwingli (14841531) were the three most influential leaders of this movement, which permanently divided Christian Europe. Each demanded toleration for their own movement, but could be intolerant of other religions. Early Catholic responses included violent repression of the Protestants, but Humanists like Desiderius Erasmus (1466?1536) called for a more irenic response of continuing dialogue and peaceful admonition.

Early Protestants soon justified being left alone based on their interpretations of the Bible. Spiritualists like Hans Denck (c. 14951527) and Sebastian Franck (c. 1499c. 1542) and mystics like Jakob Böhme (15751624) felt that God is within every man, and religious individualism is God's purpose. Persecuted Anabaptists from Balthasar Hubmaier (14851528) and David Joris (c. 15011556) to Thomas Helwys (c. 1550c. 1616) and Leonard Busher (dates unknown) argued that religious persecution is against the spirit of Jesus Christ and that judgment about matters of faith should be left to God. Menno Simons (14961561), founder of the Mennonites, argued for Christian pacifism, and Italian Protestants like Bernardino Ochino (14871564) and Celio Secondo Curione (15031569) defended their right to religious toleration on such grounds as faith is a gift from God, it is tyranny to punish an error of the soul, and God's church has room for great variety.

At first the Protestants could claim the high moral ground because they did not use violence like their Catholic opponents. Then, in 1553, Michael Servetus (15111553) was burned for antitrinitarian heresy in Calvin's Geneva. This provoked Sébastien Castellio (15151563) to write some of the first sustained defenses of toleration. De haereticis (1554; Concerning heretics) collected the irenic opinions of several writers and essays by the author under false names. "Heretic" is just the word we use to describe those with whom we disagree, he asserts. The suffering of persecution is actually the sign of a true Christian, and persecution of people who are acting in accord with their consciences promotes hypocrisy and is harmful to everybody. In later works Castellio drew on the ancient skeptics for their rejection of pretended certainty and argued for the separation of church and state. Other writers including Jacobus Acontius (14921566) and Mino Celsi (d. c. 1575) followed up on Castellio's thinking. Among these, Dutchman Dirck Coornhert (15221590) insisted that civil unity was more important than religious unity; he was one of the first to argue in favor of tolerating atheists.

Throughout the early modern period, the ideal of the primitive church as voluntary and nonviolent appealed to many people. It could be carried to the point where Pietist Gottfried Arnold's Impartial History of Churches and Heretics (16991700) redescribed most alleged heretics as pious, and most of the orthodox as the real heretics.

Catholic toleration.

In the Anglophone world there has long been a tendency to claim that most theories of toleration came from the Protestant side. But Father Joseph Lecler found a Catholic writer in favor of toleration for almost every Protestant toleration theorist. For example, Cardinal Reginald Pole (15001558) developed the thought that "Heretics be not in all Things Heretics" into a defense of toleration. In the France of the religious civil wars of the sixteenth century, Chancellor Michel de l'Hôpital (15051573) strove for compromise and toleration between the Calvinists and Catholics, partly on the basis of his own Catholic religious convictions. The great author Michel de Montaigne (15331592) never renounced Catholicism even as his Essays (15801595) contained many reasons for toleration drawn from individualism, skepticism, and a deep sense of the bodily nature of human beings. Such thinkers were sometimes called "politiques" because of their arguments for toleration on practical political grounds.

Jean Bodin (15301596) is an intriguing figure, ostensibly Catholic, but he could have been a Judaizer. In several works including Colloquium of the Seven about the Secrets of the Sublime (c. 1588) he argued for nonviolence, neutrality, and mutual agreement not to discuss differences that might lead to fighting.

The Spanish conquest of Latin America led to much abuse of the natives, partly on the ground that they were not good Christians. Writers like the bishop of Chiapas, Bartolomé de Las Casas (14741566), wrote in their defense. Half-Spanish half-natives like Felipe Guaman Poma (15321614) wrote to reconcile the two cultures, to little effect. Garcilaso de la Vega, known as "the Inca" (15391616), also spoke up for tolerance from the native side.

By the mid-eighteenth century active persecution of Protestants in France had died down, but in 1762 Jean Calas, a Protestant, was the victim of a judicial murder. The famous writer Voltaire (16941778) took up the cause, publishing A Treatise on Toleration (1763), which received European-wide circulation and discredited such persecution in public opinion. It may have been the last major cri de coeur against religious violence, because even contemporary and later Catholic treatments of heresy such as François Adrien Pluquet's Dictionary of Heresies of 1762 and Nicolas-Sylvestre Bergier's Methodical Encyclopedia of 17881832 took for granted that heresy did not justify violence.

Antitrinitarianism (Socinianism).

Antitrinitarianism or unitarianismthe theory that Jesus and the Holy Spirit did not share God's naturewas a heresy considered as bad as atheism and persecuted all over Europe. But conditions close to anarchy have often been good for toleration. The absence of centralized power in Poland in the later sixteenth century meant that it became a haven for Lelio (15251562) and Fausto (15391604) Sozzini, founders of the antitrinitarian Socinians, and followers such as Samuel Przypkowski (15921670). They developed a battery of reasons why they should not be persecuted, most of them rooted in Scripture. Their much-anathematized writings were published in the Netherlands, which had one of the freest presses of the day. Later, many thinkers such as Isaac Newton (16421727) were clandestine sympathizers with antitrinitarianism under another of its variants, Arianism.

The Netherlands out front.

The Dutch published a great deal of toleration theory and practiced toleration to a substantial degree from the later sixteenth to the eighteenth centuries. During early decades of the Revolt of the Netherlands (15681648) almost anything could be published because of the exhaustion of the political authorities, the myriad of decentralized jurisdictions, and appreciation of the economic value of the book market. William the Silent (15331584), leader of the Dutch Revolt, wrote that repression of worship leads to hypocrisy and that no false religion would last.

In the early seventeenth century a theological dispute in the Netherlands between Gomarists and Arminians led to suppression of the Arminians, but also to many writings against that suppression. Simon Episcopius (15831643) and Jan Uytenbogaert (15571644) wrote that Christian charity and reciprocity requires freedom of conscience, even for Catholics. Hugo Grotius (Huigh de Groot; 15831645) defended a limited tolerance as part of his theory of natural law, which was developed by later natural-law theorists like the German Samuel von Pufendorf (16321694). Pufendorf's Of the Nature and Qualification of Religion (1687) claimed that the genius of the Christian religion was nonviolence, that people's thoughts were not punishable, and that the civil authorities should control religion.

Benedict Baruch Spinoza (16321677), an excommunicated Jew, wrote one of the most robust defenses of freedom of thought while living in the Netherlands. In his Theological-Political Treatise (1670) he argued for arming the state for security against the mob, and then for reining in the state in matters of religion. Pierre Bayle (16471706), a Huguenot refugee in the Netherlands, developed the most sophisticated and most tolerant theory of the century. In Letters on the Comet (1682) he showed how atheists could indeed live in civil peace, and in Philosophical Commentary on the Words "Compel Them to Come In" (1685) he developed a wide-ranging theory of toleration based on the rights of conscience, even erring conscience, that would protect not only Protestant sects, but Catholics and virtually all others as well. In his last writings, he asserted that he would rather live under an atheist king because that king would have one less reason to persecute.

The English Civil War and its aftermath.

The anarchy of the English Civil War was also fertile ground for toleration writings. John Dury (15951680), Samuel Hartlib (c. 16001662), and Johann Comenius (15921670) drew on millenarian hopes to justify reunion and peace among Protestants. Merchant and Leveller William Walwyn (16001680) wrote in favor of complete religious toleration on religious grounds. Leveller Richard Overton (fl. 16421663) argued for toleration of Jews and Catholics and made free use of humor to take down overserious persecuting pride, a method recommended in Anthony Ashley Cooper, Third Earl of Shaftesbury's Characteristics (1711). John Milton (16081674) made an impassioned case for toleration of divorce in several pamphlets, and then wrote the first major defense of that aspect of toleration known as freedom of the press in Areopagitica (1644). His work was followed up in the first substantial French and German defenses of freedom of the press by Elie Luzac (1749) and Karl Friedrich Bahrdt (1787).

Roger Williams (1603?1683) founded the English colony of Rhode Island as a haven of freedom of religion, and published The Bloudy Tenent of Persecution (1644) in favor of separation of church and state and freedom of religion on Christian grounds. William Penn (16441718) founded the colony of Pennsylvania as a haven for persecuted Quakers and published The Great Case of Liberty of Conscience (1671).

Thomas Hobbes (15881679) wrote Leviathan (1651), one of the most influential theories of absolute power in the history of political philosophy, but he has also been credited with a theory of toleration in the ruler's own self-interest. Trying to control people's thoughts may provoke too much opposition and squanders power that can best be used elsewhere.

The English philosopher John Locke's (16321704) first work on toleration opposed it (1667). But after living for some years in the Netherlands, becoming friends with Dutch toleration theorist Philip van Limborch (16331712), and reading Pierre Bayle and Adriaan Paets (16311686) he developed a theory of toleration, which he published in A Letter Concerning Toleration (1689). He relied on the Calvinist point that everyone is responsible for his own salvation, skepticism about who really knew the truth, and the political benefits of toleration. Like Milton, however, he was unable to conceive of toleration of Catholics and atheists because of their alleged political unreliability, but later wrote for legal endenization of Muslims and against licensing of the press.

Economic interests, travel writings, and belles lettres.

Beyond religious and philosophical ideas, one source of toleration in theory and practice was economics. The Dutch found that wide toleration paid off in economic growth and provided a demonstration effect for the rest of Europe. Henry Robinson's (c. 1605c. 1664) pamphlets of the 1640s and Daniel Defoe's (16601731) many writings of the beginning of the eighteenth century pointed out the commercial benefits of toleration of merchants and customers of differing religions.

Another source of tolerationist ideas was travel literature, which introduced Europeans to different customs and religions from around the world. This could include actual travel accounts; somewhat fanciful travel literature such as Fernão Mendes Pinto's Travels (1614); and imaginative works like Denis Veiras's History of the Sevarites (16751679), Defoe's Robinson Crusoe (1719), and Jonathan Swift's Gulliver's Travels (1726).

Other genres of literature could be important, too. Aphra Behn's play Oroonoko (1688) taught English audiences to tolerate Africans, Gotthold Ephraim Lessing's Nathan the Wise (1779) expressed the values of toleration for late-eighteenth-century Germany, and Karl Friedrich Bahrdt's play The Edict of Religion (1787) ridiculed Frederick William II's attempt to legislate religious conformity.

Despite all of the foregoing defenses of toleration, open admission of Socinianism or atheism remained dangerous throughout the early modern period. One recourse for Socinians, atheists, and libertines was the circulation of manuscripts and even clandestine printed works in the large underground literature of the time. Much of this literature, which included many pleas for toleration, has been explored in the French annual La lettre clandestine (1992).

Toleration of Jews.

Jews and heretics were often subjects of popular and clerical intolerance in medieval and early modern Europe, but writers could counteract some of that sentiment. Millenarians favored toleration of Judaism because they believed that the Jews must voluntarily convert before the restoration of Christ. Histories such as Jacques Basnage's History of the Jews (17071716) and Ludvig Holberg's History of the Jews (1742) helped place this much-maligned people in a more favorable light. The Jewish writer Moses Mendelssohn's Jerusalem (1783) was an eloquent plea for religious tolerance.

Nineteenth and Twentieth Centuries

It seems safe to say that although toleration of differing religions remains a political issue even into the twenty-first century, there have been few or no substantial novelties concerning the idea of toleration since the eighteenth century. Wilhelm von Humboldt's The Limits of State Action of 1852, his follower John Stuart Mill's On Liberty of 1859, and twentieth-century pleas for tolerance have largely debated, restated, and updated the theoretical ideas already in place from earlier times.

Legal Acts and Declarations

In addition to political pamphlets and philosophical arguments, from the sixteenth century on toleration can be tracked by study of the legal provisions that were decreed to grant it. One form of toleration was settled by the Peace of Augsburg of 1555, which ended some of the wars between Lutherans and Catholics. Under the formula cuius regio eius religio (the ruler determines the religion) it held that each prince could decide which of the two religions would be established in his territories and permitted adherents to the other religion to emigrate. Although not much, this was an entering wedge for wider forms of toleration. The principle was reaffirmed, this time including Catholicism, Lutheranism, and Calvinism, in the Peace of Westphalia of 1648.

The Revolt of the Netherlands against Spain after 1560 eventually gave the once-persecuted victorious Protestants the dilemma of deciding how to deal with the large number of Catholics in their territories. Pacts of tolerance were published as early as the 1570s, and in some localities Catholics were forbidden to proselytize or engage in public processions but were allowed to worship in private homes.

In 1568 the Diet of Torda in Transylvania consolidated religious enactments of the previous decades into a decree that "no one should be abused by anyone for his religion" and further similar provisions. In the following decades Anabaptists, Unitarians, Jews, and Orthodox Christians were protected by various laws and patents. In 1573 the king of Poland was forced to accede to the Confederation of Warsaw, which granted Catholics, Lutherans, Calvinists, and even antitrinitarians some protection from persecution, leading to a golden age for Socinians there that lasted for several decades until Catholicism regained the ascendancy.

After decades of civil war between Calvinist Huguenots and Catholics in France, Henry IV enacted the Edict of Nantes in 1598, which guaranteed Protestant rights to worship in their churches and even to certain fortified cities. Several other edicts of the sixteenth century attempted to settle continuing religious rivalry, but Louis XIV ended efforts to make coexistence possible by his Revocation of the Edict of Nantes in 1685. As many as a hundred thousand Calvinists fled France.

Taking advantage of the outflow of these talented and hardworking Huguenots, Frederick William I, the Calvinist great elector of Lutheran Brandenburg, issued the Decree of Potsdam in 1685, announcing that he would provide refuge to them and respect their religion. Many came and settled in Berlin, helping the city prosper.

The Toleration Act of 1689 demonstrates what the word could mean in England in that period. It suspended penal laws against Protestants who refused to conform to the Church of England. It did not lift penalties against antitrinitarians and Catholics, who were only given equal rights in 1813 and 1829, respectively. It maintained privileges such as exclusive qualification for political office for members of the Church of England. Nevertheless, this could be considered toleration because it allowed some dissenting sects that had not previously been permitted to worship in public to do so. Its perhaps unintended consequence was to keep alive the idea that other sects could eventually be tolerated, too.

Many who emigrated to the English colonies in North America did so in pursuit of religious freedom. Maryland's Act Concerning Religion of 1649 was the first to spell out religious freedom. As mentioned above, Roger Williams founded the colony of Rhode Island in order to institute religious liberty. By the later eighteenth century, the ideal of religious toleration was often institutionalized by declarations of rights. The Virginia Declaration of Rights of 1776, several other state declarations, and the First Amendment to the United States Constitution (1791) provided for religious freedom. In France, the "Declaration of the Rights of Man and of the Citizen" of the National Assembly in 1789 provided that "No one shall be disquieted on account of his opinions, including his religious views, provided their manifestation does not disturb the public order established by law" (Article 10). The United States and France served as models for such ideals and declarations in many countries throughout the next century.

Twentieth-century declarations.

In the twentieth century, the United Nations internationalized the tradition of declarations of rights to toleration. In 1948 the General Assembly adopted the Universal Declaration of Human Rights, providing that "everyone has the right to freedom of thought, conscience and religion; this right includes freedom to change his religion or belief, and freedom, either alone or in community with others and in public or private, to manifest his religion or belief in teaching, practice, worship and observance" (Article 18).

In 1996 the United Nations Educational, Social, and Cultural Organization (UNESCO) issued a "Declaration of Principles of Tolerance." Ignoring the ordinary usage of tolerance as referring to the middle of the spectrum between persecution and warm embrace, UNESCO redefined it by fiat as "respect, acceptance and appreciation of the rich diversity of our world's cultures" (Article 1.1). This was surely well-intended as an effort to move people who are unjustifiably opposed to diversity toward more open-mindedness. But if warm embrace becomes the exclusive meaning of toleration, we will surely need another term for our attitude or policy toward the things we may justifiably not respect, accept, or appreciate, but also do not persecute.

TOLERATION. Toleration (or its cognate, tolerance) denotes the readiness of an individual or a community to permit the presence and/or expression of ideas, beliefs, and practices differing from what is accepted by that individual or by the dominant part of the community. Toleration demands forbearance only; it does not require approval or endorsement of the tolerated ideas, beliefs, and practices. A tolerant person respects differences between him- or herself and other people; a tolerant community respects differences between groups and/or among individuals within the social totality. Toleration is thus antithetical to the persecution or repression (systematic or individualized) of ideas, beliefs, and practices that differ from one's own. Indeed, a tolerant person or society will protect the ability of such ideas, beliefs, and practices to persist even while acknowledging disagreement with them.

In early modern Europe, the main object of toleration in reality and as an ideal was difference of confession among religious communities, all of which claimed to be Christian. The Protestant Reformation had fragmentedpermanently, as it turned outthe institutional and doctrinal unity of the Latin Christian Church that the faith had supposedly upheld since the time of St. Paul. During the sixteenth century, under the impact of Lutheran and Calvinist condemnations of the impurity of the visible Roman Church, not to mention the English Church's institutional break with Rome and the emergence of extreme sects such as the Anabaptists, Christianity was forced to reinvent itself as a creed united in faith but divided in rite. This situation has commonly led scholars to conclude that only in the post-Reformation context did the ideal vision and real conduct of tolerance enter into Europe, expressed by various proclamations of toleration as well as by the theoretical statement found in the Epistola de Tolerantia (1689; Letter on toleration) of John Locke (16321704).

Yet the assertion of the singular modernity of toleration, arising in the aftermath of the Protestant Reformation, masks the complexity of its history. Prior to the sixteenth century, certain voices at the core as well as on the periphery of European society were prepared to countenance the presence of dissenters and even heretics within Christianity as well as the existence of various non-Christian convictions. Moreover, other important issues, such as the discovery of the New World with its large population previously unexposed to the Christian faith, also drove the debate about the extension of forbearance to cultures and religious rites utterly alien to Europe. Finally, no particularly compelling evidence suggests that the desire to persecute forms of difference and dissentin religion as in other fields of human endeavorabated with the rise of modern Europe. Even those prepared to tolerate certain divergent Christian confessions were equally ready to exclude and brutally suppress other self-identified ChristiansRoman Catholics, Anabaptists, Hutterites, millenariansnot to mention deists, atheists, and similar free thinkers.

This context needs to be considered when assessing the strengths and weaknesses of the modern European approach to toleration. Even before the monk Martin Luther (14831546) nailed his Ninety-Five Theses to the church door at Witten-berg in 1517, Europeans were grappling with the consequences of their encounter with the indigenous peoples of the Americas following the discoveries of the 1490s. Spain and Portugal in particular sought and received the authorization of the Roman Church to conquer and settle the lands of the Caribbean and Central and South America under the guise of evangelizing and converting the native populace. Some thinkers recoiled with considerable horror from the slaughter and enslavement that ensued. The towering figure of the School of Salamanca, Francesco de Vitoria (c. 1486?1546), objected to the appropriation of the Aristotelian categories of barbarism and slavery by nature. Following de Vitoria, the Dominican bishop and former conquistador Bartolomé de Las Casas (14761566) composed a series of writings in Spanish as well as Latin defending the rights of the native population to maintain their cultural, political, and religious traditions and practiceseven such controversial rites as human sacrifices, not to mention refusal of Christian missionaries and resistance to conquest. In a famous debate with the Scholastic advocate of Spanish dominion over the Indians, Juan Ginés de Sepúlveda, held at Valladolid in 1550, Las Casas used the materials of Aristotle's corpus, Thomism, and canon law to refute the assertion by the Spanish crown of its right to impose religion and civilization at swordpoint upon indigenous Americans. Rather, a Christian attitude toward the Indiansrooted in divine and natural law as well as the teachings of the pagan philosophersdemanded forbearance of their way of life, even if Europeans found their faith and rituals abhorrent.

At one time, scholars viewed the Reformation as a singularly positive stimulus to the promotion of toleration. It is true that Martin Luther, at least in some contexts, appears to defend tolerance on the grounds that the magistrate should be concerned only with the care of the body and does not have the tools at his disposal to control or alter the state of a person's soul. But other reformers, most notably John Calvin (15091564), were inclined to deny any measure of forbearance for religious positions that did not strictly conform to their new orthodoxy. Indeed, one of the important early defenders of toleration during the sixteenth century, Sebastian Castellio (or Sébastien Châteillon) (15151563), published pseudonymously a treatise entitled De Haereticis, an Sint Persequendi ('Of heretics, whether they should be persecuted') in reaction to Calvin's instruction to the city of Geneva in 1553 to burn a visiting Spanish heretic theologian, Michael Servetus, who opposed the doctrine of the Trinity. Castellio argued that coercion is an inappropriate tool for effecting a change of religious views, since Christian belief must be held with sincere conviction. Hence, clerics and magistrates must refrain from the persecution of convinced Christians who cling to doctrines that do not coincide with official teachings. While Castellio did not go so far as to license broad dissemination of heterodox theology, he maintained that a Christian's duties extended to tolerating the free and honest faith of fellow believers even in the face of disagreements of understanding and interpretation.

In the short term, voices such as Castellio's went unheeded. Rather, in places such as France and Germany, where the Reformation enjoyed greatest support, violent harassment of religious minoritiesCatholic or Protestantpersisted and often threatened to erupt into full-scale religious warfare. It is true that some rulers and regions found ways to stamp out conflict, either by fiat or by negotiation. The most famous resolutions, such as the Religious Peace of Augsburg (1555) and the Edict of Nantes (1598), tended to be short-lived. But in Switzerland, where Reformed and Catholic communities often lived side-by-side, accommodation concerning the sharing of power and mutual respect for different rites succeeded in eliminating persecution in many areas. The Dutch Republic managed to achieve a similar arrangement, as did a number of eastern European states, including Poland, Transylvania, and Moravia.

These tolerant practices were certainly approved by many thinkers who subscribed to a range of confessions. Desiderius Erasmus (1466?1535), one of the leading humanists of the age and a Catholic who nonetheless sympathized with the cause of reform, promoted a vision of toleration that he derived from the principles of classical rhetoric. According to Erasmus, violence was an inadequate, as well as un-Christian, means of dealing with unbelief. Only by speech might those who strayed from truth be convinced of the error of their ways. And both preaching and conversationthe two predominant ways in which the orthodox express truth to the errantdemanded that one tolerate the heterodox, if only in order to achieve conversion. Another humanist, Jean Bodin (1529/301596), pushed this discursive paradigm of tolerance even further. In his Colloquium Heptaplomeres de Rerum Sublimium Arcanis Abditis (1588; Colloquium of the seven about secrets of the sublime), Bodin adapted the standard literary genre of the interreligious dialogue, in this case between advocates of the major world religions and of various philosophical interpretations of divinity. Unlike previous texts of interreligious dialogue, however, Bodin's discussion produced a stalemate: no one changed his mind and no conversions occured. Bodin's point has been understood as the promotion of tolerance, either because the relative merits of creeds cannot ultimately be demonstrated or because dialogue makes us realize that all religions have their merits and demerits. The text of the Colloquium was passed around secretly in manuscript for centuries, none daring to publish until the middle of the nineteenth century such a reputedly notorious challenge to the self-evident superiority of Christianity.

The cause of toleration became more visible as a political and intellectual force during the seventeenth century. As a practical aim, the Levellers in England during the 1640s made freedom to dissent from the established religion a central plank of their political program. Likewise, major figures in European philosophy weighed in on the side of freedom of religion. Thomas Hobbes (15881679) recognized the mischief that religion caused to the maintenance of public peace and order. His solution to the potential for religious conflict was not persecution of dissent but acknowledgment that, since faith was an inward matter, coercion of belief pertained to neither church nor state. So long as one's convictions about God and the afterlife did not produce external political dispute, Hobbesian logic required that the sovereign permit subjects to embrace whatever confession they liked. Baruch Spinoza (16321677) followed Hobbes in recognizing the inability of the government to control the inward faith of individuals. He therefore claimed a broad application for a right to liberty of thought and conviction without inference from a sovereign's (or a church's) determination of the truth or falsity of an individual's ideas. On the one hand, Spinoza proposed to employ the armed might of the state to rein in the activities of intolerant clergymen and mobs. On the other hand, he set clear limits on the power of the magistrate to persecute all forms of religious and intellectual dissent. The German jurist Samuel Pufendorf (16321694), too, advocated the protection of religious freedom in the name of the interests of the state. The sovereign must exercise control over the affairs of religion, not in order to impose "true" religion, but in order to ensure that "hotheads, pride, fame, and ambition" do not lead to civil conflict and sedition.

When viewed from the perspective of this intellectual backdrop, the concept of tolerance proposed by John Locke does not appear especially innovative or creative. Locke built his theory on a clear distinction between the aims of the church and the purposes of government. The church seeks to care for souls, whose condition cannot be changed by force but only by persuasion. Since the role of government is the protection of the life, liberty, and estate of subjects, its work cannot extend to the business of religion. For Locke, the magistrate should maintain public tranquility and defend individual rights. Thus, liberty of conscience was justified in the case of most Christian (and perhaps some non-Christian) rites. Of course, Locke insisted that government must take an appropriate interest in religious ideas and rites when they were capable of undermining social trust and political obedience. For this reason, he sought to exclude atheists and to ban any religious institutions that taught the superiority of the church to the temporal magistrate in civil affairs.

While Locke's account of toleration has received by far the most attention, the version proposed by the pre-Enlightenment thinker Pierre Bayle (16471706) is perhaps the most consistent and thoroughgoing of the late seventeenth century. Bayle is sometimes termed a Calvinist advocate of tolerance. Seeking to refute a range of arguments for persecution, Bayle baldly asserted that all forms of suppression of religious diversity encourage hypocrisy and erode social order. Indeed, to harass religious dissenters constitutes an affront to God. An erring conscience, if it be held in good faith, deserves as much protection as a correct onea principle that Bayle extended even to atheists. Unlike many of his predecessors, he did not embrace a strict distinction between the inward and the outward, and he thus took seriously the ability of the threat of coercion to weaken the beliefs of individuals. But should a person be forced to surrender his or her inner convictions, an act of sacrilege has been committed because God forgives error on account of the purity of the intention. A false belief sincerely held was regarded by Bayle to be superior in the eyes of God to a true conviction held only as a result of external compulsion. Bayle did admit that rites which are likely to detract directly from civil order may be constrained or excluded, but his main concern seems to be fanatical sects that inspire their adherents to engage in conduct that endangers the health and well-being of other inhabitants of the community.

The themes highlighted by seventeenth-century proponents of toleration received further elaboration during the eighteenth century, in particular, the problem of balancing personal liberty of conscience against the need for public order and obedience. For instance, the journalist and novelist Daniel Defoe (16601731) railed in his writings against conformity, and he was only too happy to satirize the foibles of the persecutorial impulse. Although a dissenter himself, he once dared to publish a hoax pamphlet, "The Shortest Way with Dissenters" (1702), purportedly written by a High Church spokesman, that called for the hanging en masse of religious nonconformists.

The two most intellectually powerful eighteenth-century proponents of toleration were Christian Thomasius (16551728) and Immanuel Kant (17241804). Thomasius, a central figure of the so-called "civil Enlightenment," adopted a jurisprudential approach according to which all supposed heresies were framed in a historical light, and the charge of dissent was viewed simply as a means for different sects to vilify one another. Theological and metaphysical questions should be set aside in favor of a prudential law of religion (Staatskirchenrecht) that permitted and regulated expressions of religious diversity. Like Hobbes, Thomasius showed how an absolutist conception of government might yield a thoroughgoing principle of tolerance. Kant was certainly the more famous figure in the promotion of tolerant attitudes. His essay Was ist Aufklärung? (1784; What is enlightenment?) pronounced a human duty to become liberated from self-imposed mental chains and to develop an independent capacity for critical reflection. This requires a public sphere that is fully tolerant of differences in thought and action among individuals. Yet Kant also asserted the overriding duty that each person has to obey government, so that the subjects of a ruler have a supererogatory responsibility to refrain from public expression of ideas or doctrines that might promote disobedience to the sovereign will. For Kant, too, toleration did not necessitate the institutional primacy of rights associated with political liberalism.

Despite Kant's insistence upon obedience, a considerable number of Enlightenment thinkers in fact defended various forms of toleration in the eighteenth century. Thomas Paine (17371809) dismissed the terminology of "toleration" itself as inherently intolerant, since it depended upon the grant of the state, preferring to speak of basic rights associated with freedom of conscience and thought. The French philosophes, who were the main champions of enlightenment, likewise announced themselves to be defenders of tolerance. But perhaps it was with the "Declaration of the Rights of Man and the Citizen," approved by the National Assembly of France on 26 August 1789, that such a basic liberal conception of liberty of belief and worship received its characteristic statement.
