I have to agree that faith can be rational. My biggest argument for this how the human psyche works. A person can say they have faith (in some cases even a gut feeling) but what they are experiencing in reality is a sum of what they subconsciously know. The example having faith that your wife is not cheating on you stands behind this point in that subconsciously you know that you know certain things about her day or you knew where she was at certain points. Even religion is in reality just a sum of what collective knowledge you have and whether or not I'm your mind it is collectively enough proof for you to believe.
