error. “Every man has commission to admonish, exhort, convince another of error, and, by reasoning, to draw him into truth” (p. 14). Locke would thus have been dismayed by a society such as ours in which the onus on “respect” frequently produces a timid unwillingness to challenge the beliefs of others.
Antinomians
Given the powerful nature of Locke’s case for religious tolerance, it comes as a shock that, near the close of the Letter, he excludes atheists and Catholics from toleration. There is no gainsaying that he rejects the possibility of tolerating atheists, whom he claims have no motive for keeping rules, since they lack fear of divine punishment. “Promises, covenants, and oaths, which are the bonds of human society, can have no hold upon an atheist” (pp. 52–53). Spinoza and Bayle disagreed. Locke’s position on Catholicism, however, needs finessing, since he did not, in fact, exclude the theoretical possibility of tolerating Catholics. Although Catholics held absurd beliefs, such as transubstantiation, the absurdity of another’s belief is not, in itself, a ground for coercion. What rendered Catholics unable to be tolerated was that they held political and moral positions that fundamentally threatened civil society. These were twofold: that the pope can depose heretic princes and authorize his followers to overthrow such princes; and that “faith need not be kept with heretics”: in other words, that rules of honesty and promise-keeping need not apply when Catholics deal with heretics. The implication of Locke’s position was that if Catholics could discard their uncivil beliefs, they could then be tolerated. Eighteenth-century Catholics took succor from this argument and strove to demonstrate that Catholicism was not committed to papal political dominion nor to breach of faith with heretics.
What Locke was precluding was not Catholicism as such, but antinomianism. An antinomian is one who holds that ordinary moral laws are trumped by the superiority of religious “truth.” This is to put religion in collision with reason and natural law, which are also the works of God and not in conflict with revelation. Antinomians hold either that they are divinely inspired to rule (the ultimate form of a godly commonwealth) or, on the contrary, that they are exempt from rule (the ultimate form of godly anarchy). Catholic claims that the pope had Christ’s commission to dictate to all nations and Calvinist claims that the “elect” should rule (“the rule of the saints”) were equally antinomian. There are hints that Locke had Puritan fanatics in mind as being also potentially intolerable. There are plenty of other varieties of antinomianism, then and now, such as the proposition that a particular territory belongs to a particular group because “God gave it to them,” or that one state should fight a war against another because it deems it to be the “antichrist.”
Locke was explicit that governments should concern themselves with religious behavior only insofar as it was dangerous to society’s temporal interests. Eccentric behavior in places of worship is no more harmful to civil society than eccentric behavior in marketplaces. Conversely, terrorist behavior in a church was as legitimately subject to surveillance as in a marketplace. Locke readily accepted that the state might need to exercise vigilance with regard to some religious groups, though the state should be explicit about the grounds for its suspicion. Conversely, citizens had a parallel duty to be vigilant in ensuring that those in charge of the state were not framing policy in accordance with “godly” agendas. Antinomianism can manifest itself from above as well as from below.
Locke’s Transition
Although this account has, thus far, dwelt on the Letter, Locke reflected and wrote about toleration across four decades. Conspicuously, he did not hold the same views in 1690 that he held in 1660. When monarchy and the Church of England were restored after the Civil Wars and republic, Locke had written in defense of the civil magistrate’s authority to impose a uniform public worship. Locke composed these essays, now known as the Two Tracts on Government (1660–62), while a young scholar and teacher at Oxford University, although they remained unpublished until 1967. They reveal a Locke deeply fearful of civil anarchy driven by religious fanaticism. Like most of his compatriots, he thought the Civil Wars had opened a Pandora’s box of wild “enthusiasm” and antinomian zeal-otry masquerading under the banner of conscience. He argued within the theological tradition of “things indifferent” and concluded that because most matters of worship and religious discipline are indifferent, the nonconformists had no conscientious ground for objecting to the imposition of order.
A striking feature of the Tracts is that they epitomize the argumentation that Locke would later come to oppose. For reasons that still remain unclear, by 1667 he had decisively changed his mind. Probably most important was his new association with Lord Ashley, the future Whig leader and Earl of Shaftesbury, and his consequent move from Oxford, the ideological home of Anglican churchmanship. Locke settled in the more cosmopolitan London, close to the court of Charles II, which had its own reasons for seeking toleration, as the king was either religiously indifferent or crypto-Catholic. Locke’s visit to Cleves in Germany in 1666 was also an eye-opener, for he was agog, in that tolerant city, that it was possible for Lutherans, Calvinists, and even Catholics to worship openly and yet live in peace. Locke’s conversion was signaled in his Essay on Toleration (1667), another piece that remained unpublished until long after his death. Containing arguments that would recur in the Letter, the Essay may have originated as a memorandum for Ashley and in turn for the royal court.
A large archive of Locke’s private notebooks and memoranda survives today. In these documents he constantly returned to consider the case for toleration. These materials have been gathered together in this volume under the heading “Fragments on Toleration.” Locke’s papers explore a number of themes that are not always prominent in the Letter. They include polemical critiques of churchmen who, in essence, echoed the arguments of his own early Tracts, which he had now abandoned. Several of his memoranda relate to Catholicism, illustrating his vehement hostility to a church that insisted on its own infallibility. At the same time, Locke continued to be disturbed by the dangers of Protestant antinomianism, not only in the dissenting sects but also by all forms of “enthusiasts,” whose mystical spirituality dangerously threatened to exceed the boundaries of Christian reasonableness.
Priestcraft
Catholics, antinomians, and “enthusiasts” do not exhaust the categories of the religious against whom Locke’s animus was directed. There is a stridently anticlerical tone in Locke’s Letter and in other writings, evincing his insistence that much that passes for Christian doctrine is merely priestly fabrication, supervening upon Gospel simplicity. Locke is constantly hostile to clergies. Those who persecute do so “upon pretence of religion”; they are bigots who seek personal power and wealth, rather than the salvation of others (p. 8). Such a charge had long been at the heart of the Protestant assault on medieval Catholicism. Yet, for Locke and increasingly for his contemporaries, priestly usurpation was not a Catholic monopoly. There are passages in Locke that prefigure the Enlightenment’s critique of “priestcraft,” a word that became fashionable in the 1690s and that Locke uses in The Reasonableness of Christianity. It denoted a general theory of the propensities of all priesthoods to pervert religion in pursuit of earthly domination. Religious creeds and clerically inspired political creeds are apt to be ideological in the strict sense of that term: they are doctrines that serve power rather than truth. Locke thought that the doctrine of the divine right of kings was a salient case: priests elevate princes so that princes will return the favor by awarding churches the trappings of temporal power. Over a longer historical span, it is possible to see that Locke’s claim that religions are projections of temporal power and worldly aspirations is one of the high roads to atheism. Locke provided a signpost to that road but did not himself make the journey. After all, the charge that religion has been perverted by worldliness lies deep in the Christian tradition itself. In this sense, distinguishing the Enlightenment from the Reformation is far from straightforward.
Early Reception
By the end of the eighteenth century, Locke’s Letter Concerning Toleration had been published in twenty-six editions, as well as being included in nine editions of his Works and in the Œuvres diverses de Monsieur Jean Locke (1710). It appeared in Latin, French, German, and Dutch and achieved its first American edition at Boston in 1743. Voltaire’s edition of 1764 accompanied his own Traité sur la tolérance,
