Morris explains and expounds upon Pascal's thought in an easy to read manner. A apologetic work in the line of G.K. Chesterton and C.S. Lewis.
Pascal is an example of a brilliant scientific mind who found it very reasonable to believe in God, or more specifically a Christian God. Morris, through Pascal, shows that faith and reason can take you farther than either can alone. A great thought provoking book for the person seeking understanding of those hard questions.
One addendum to the reviewer of May 9, 2000 who said "Pascal was a Jansenist, the Roman version of a Catholic":
Jansenism is named after Cornelius Jansen, who was the Roman Catholic Bishop of Ypres in the early 17th century. His main work, Augustinus, was published after his death. In this work, he claimed to have rediscovered the true teaching of St. Augustine concerning grace, which had been lost to the Church for centuries.
Jansenism was never approved of by the Roman Catholic Church, and while Pascal had several Jansenist friends, and wrote in support of their cause, it is questionable whether he himself was a Jansenist. Morris addresses this issue in pages 8 & 9 of this book.
