Lettres provinciales (Provincial
letters) are a series of eighteen letters written by French philosopher and
theologian Blaise Pascal under the pseudonym Louis de Montalte. Written in the
midst of the formulary controversy between the Jansenists and the Jesuits, they
are a defense of the Jansenist Antoine Arnauld from Port-Royal-des-Champs, a
friend of Pascal who in 1656 was condemned by the Faculte de Théologie at the
Sorbonne in Paris for views that were claimed to be heretical. The First letter
is dated January 23, 1656 and the Eighteenth March 24, 1657. A fragmentary
Nineteenth letter is frequently included with the other eighteen.
