What happened
Pierre Bayle, a French Protestant who had fled to the Dutch Republic to escape Catholic persecution, published his Historical and Critical Dictionary in 1697, expanded in 1702. Structured as an encyclopedia of biographical and historical entries, the Dictionary used dense footnotes to question received claims in theology, history, and philosophy, applying skeptical scrutiny to sources that earlier scholarship had simply repeated. Bayle argued, controversially for his time, that a society of atheists could in principle be as moral as a society of believers, since moral behavior does not require religious belief to motivate it.
Why it matters
The philosopher Ernst Cassirer later called the Dictionary the "Arsenal of the Enlightenment" because so many 18th-century writers, including Voltaire and the authors of Diderot's Encyclopedie, mined it directly for arguments and citations. Inventories of private European libraries from the period show it was one of the most widely owned reference works of the century.
How we know
The Dictionary survives in its original French editions and later translations; the Stanford Encyclopedia of Philosophy's entry on Bayle traces its 1697 and 1702 publication and Cassirer's assessment from these editions and later scholarship.
