1647 – 1706
Pierre Bayle (1647–1706) was a French skeptic and advocate of religious toleration, best known for his monumental Dictionnaire historique et critique (1697). Writing from exile in Rotterdam, he subjected theological and philosophical claims to rigorous critical scrutiny, arguing that reason and faith are irreconcilable and that moral virtue is independent of religious belief. His defense of toleration and his fideistic skepticism made him a formative influence on the Enlightenment.
