This faith stands on its own feet and does not need help from understanding. Anselm believes in God anyway and does not need, e.g., the ontological proof for God's existence. The Cur deus homo is actually one chain of syllogisms. It gives me pleasure to see how the various tenets of my faith harmonize with one another, how what I know to be the case could not possibly be otherwise, how it is not just true but also reasonable , logically necessary. If I could not prove this , I would simply have to live with my incapacity, I would have hit my boundaries and would have to accept them.
Reason is a double agent.
On the one hand, reason can confirm faith in the way described above. Logical deductions are, according to Anselm, good exercises, games and pastimes for persons whose faith is solid and would certainly not need logical help. Everyone else, however, ought to strengthen their faith by devotional habits. At the end of the work, we find a logical analysis of Anselm's ontological argument. Bencivenga's book is certainly one of the best examinations of Anselm's thought ever written.
