Toleration and Its Limits
In one line Locke argued that force cannot make belief, so the state should leave belief alone; then he drew limits we still argue over.
John Locke’s A Letter Concerning Toleration (1689) rests on one claim. The state exists to protect life, liberty, health and possessions, which he called civil interests. Saving souls is not its business. Force can make people say the words, but belief comes by persuasion, and a belief professed under threat saves no one.
That protects a great deal. A church becomes a voluntary society, and the state may not punish anyone for which one they join or leave. No church may borrow the state’s sword to punish the others.
Then come the limits, and they are the interesting part. Locke would not tolerate opinions that attack the rules of society, or people who owe allegiance to a foreign ruler. Nor would he tolerate atheists, since he thought promises lose their hold without God. Readers since have asked whether those limits follow from his argument or only from his fears.
The school assembly
A village school in Priya’s town holds a daily prayer. A new family, the Osmans, asks to be excused. The head, Mr. Doyle, worries that this will spread. Priya, on the governors’ board, raises Locke’s point: a prayer said because attendance is compulsory is not a prayer. The school’s job is reading and arithmetic, not souls.
The board lets the Osmans sit it out. Then the Osmans ask that the prayer stop for everyone, and the board finds Locke’s question harder than it looked.
Try this today Name one belief you find wrong but think should be tolerated, and say in a sentence why force would not fix it.
