Book excerpt: Although Pascal was one of the small group of thinkers who influenced Nietzsche profoundly, and although Nietzsche claimed to have Pascal's blood running in his veins, Pascal did not succeed in getting him to share his intense preoccupation with the question of the truth of Christian belief. Not its truth but the value of its effects on mankind became the focus of Nietzsche's vitriolic anti-Christian polemics. This study, one of the very few on the Nietzsche/Pascal relationship, explores and appreciates the religious thought of each. It also assesses the nature and ground of their relationship and investigates the reasonableness of the Faith that divided them.
