Roger Ariew masterfully renders the oddities of seventeenth-century French vocabulary and syntax in this eloquent and philosophically astute translation -- the first complete English translation based on the Sellier edition of Pascal's manuscript, widely accepted as the version closest to what Pascal intended. Ariew provides a general Introduction that discusses the the life and times of Pascal, a select bibliography of primary and secondary sources, a chronology of Pascal's life and works, concordances between the Sellier and Lafuma editions of the original, and an index.
