About this book

What happens when a moral rule becomes so flexible that almost anything can pass?

In The Provincial Letters of Blaise Pascal, a church quarrel becomes a sharp, witty inquiry into conscience. Writing as Louis de Montalte, Pascal defends Antoine Arnauld, who faces condemnation by the theologians of the Sorbonne. The opening letters explore divine grace: how, according to the theologians in dispute, it acts on the human will.

Then a cheerful Jesuit guide explains his order’s moral methods, and Pascal presses a bolder charge. He argues that some Jesuit writers bend Christian rules until sin almost disappears. Drawing on their books, he turns laughter into a weapon. These eighteen letters bring together the dispute over grace, arguments about moral conduct, and Pascal’s replies to his critics.

What you’ll discover

  • An outsider among theologians Follow a questioning narrator into a church dispute where words carry serious consequences.
  • The puzzle of grace Explore the disagreement over divine grace that places Arnauld and the Jansenists under scrutiny.
  • A cheerful moral guide Meet the Jesuit father whose explanations give Pascal’s satire its lively point of attack.
  • Rules under pressure Examine probabilism and the direction of intention, methods Pascal challenges for making moral demands easier.
  • Laughter with a purpose Watch Pascal combine wit, close references, and forceful argument as he answers his opponents.

Who will love it

You will enjoy this if you like satire with a serious aim, sharp arguments in lively conversations, and a clash between conscience, church politics and the printed word.

In short

What if a curious young man sat down with a smiling priest and asked, one question at a time, how many sins his order could excuse? That is the scene Blaise Pascal builds in The Provincial Letters, written in Paris in 1656 and 1657.

Learned quarrels can hide behind words without meaning

Letter one opens with a surprise. The narrator expects the Sorbonne debate to be grave, yet the supposed heresy is refusing to say that the righteous have a proximate power.

What are the Provincial Letters about?

They are nineteen letters from 1656 and 1657. The first four deal with the Sorbonne dispute over grace and Arnauld, the middle ones with Jesuit moral teaching, and the last with the Jesuit replies and the charge of heresy against the Jansenists.

Who are the Jansenists and the Jesuits in the letters?

The Jansenists follow Jansenius and Augustine on efficacious grace and strict morals, with Arnauld and Port-Royal as their centre. The Jesuits are the Society of Jesus, whose casuists Pascal quotes at length, including Escobar, Bauny, Lessius and Molina.

What does probable opinion mean in the book?

It is a casuists' rule that an opinion may be followed if one serious doctor holds it, even when the opposite is more probable or safer. Pascal argues that this lets almost any act be defended.
