The Revocation of the Edict of Nantes
In October 1685, Louis XIV revoked the Edict of Nantes, which for eighty-seven years had guaranteed French Protestants the right to practice their faith and pursue their trades. The revocation was a triumph of religious uniformity and an act of economic self-mutilation whose consequences Landes documented across his career. The Huguenots were disproportionately represented in France's most skilled and commercially productive trades: silk weaving, watchmaking, glassblowing, silversmithing, printing, finance. They were not merely skilled workers but nodes in networks of knowledge, trade, and trust extending across Europe. Between two hundred thousand and one million left France — the estimates vary widely, but even the lowest figure represents a staggering loss. They went to England, the Netherlands, Brandenburg-Prussia, Switzerland, the Cape Colony, and the American colonies. Every receiving society was enriched. France was diminished.
In the AI Story
The deeper damage was not the loss of skilled labor — which could, in theory, be replaced over time — but the destruction of networks. The Huguenots carried relationships of trust, channels of information, and cross-border connections that had taken generations to build. Networks do not regenerate when you re-admit the people you expelled. The trust has been broken. The connections have been rewired. The knowledge has found new homes.
The episode is Landes's most frequently invoked illustration of the structural principle that tolerance is economically productive and intolerance is economically self-defeating, regardless of the moral arguments that can be made on either side. The mechanism is not sentimental. It is that innovation requires the collision of different perspectives, collision requires proximity, and proximity requires tolerance. An economy composed entirely of people who think the same way will produce incremental improvements within existing paradigms but not the paradigm-breaking insights that come from the collision of incommensurable worldviews.
For the AI age, the episode establishes the template: societies that enforce intellectual conformity — whether through political censorship, cultural pressure, educational standardization, or algorithmic filtering — will bleed cognitive diversity with the same quiet efficiency that Louis XIV bled French commerce. And the societies that welcome heterodox thinkers will be enriched by exactly the same mechanism that enriched Amsterdam, London, and Berlin after 1685.
Origin
The edict was revoked by the Edict of Fontainebleau, issued at Louis XIV's court in October 1685. The original Edict of Nantes had been promulgated by Henri IV in 1598 as an instrument of religious pacification after the French Wars of Religion.
Key Ideas
Tolerance as economic infrastructure. Religious tolerance functioned, in the French case, as the structural condition under which commercial networks could span confessional lines and knowledge could flow across boundaries.
Networks are not replaceable. The deepest damage of expulsion is not the loss of individuals but the destruction of the relational infrastructure that made individuals productive — damage that cannot be undone by re-admission.
Receiving societies as beneficiaries. The distributed gains of intolerance — every rival nation enriched by France's expelled productive class — illustrate the competitive dynamic that rewards tolerance structurally.
The mechanism scales. The AI age version of the same principle: societies that enforce intellectual conformity will lose cognitive diversity to those that welcome it, with the amplifier making the gains and losses more immediate than the centuries-long timescales of the seventeenth century.
