He launched an assault on the moral theology of the Jesuits during the height of the Jansenist controversy and left a rather amusing and enlightening work what is beautiful in its turn of both phrase and thought. The first half of the letters is Pascal's attempt to relate the opposing views in the controversy and to illuminate the Jesuit views in all their folly. The second half (which is, unfortunately, a bit more functional and less engaging) is a mix of parry and riposte as Pascal swats away the arguments of his opponents.
