I'm not sure that's true, Stuart. You've been here on a Christian Website for quite awhile. While 'faith' is certainly a different approach, it isn't completely blind. Kierkegaard's 'blind leap' didn't mean uncalculated, rather that some things have to be seen from the inside. All truth is circular and encapsulated of itself. Its its own veracity. There is a bit of humor among philosophy students: 1 claims nothing is real and the other lines up with a baseball bat and says 'let's test that theory.' My assertion that God exists is definitely a baseball bat: it is inevitable that His presence will be proven. I've been hit a number of times with that bat, if I ever felt the leisure to think something isn't real, that part is pretty much gone now. I've too many lumps that speak, and for me, are 'proof enough' not to ask again. It isn't always nor necessary that faith is a school of hard knocks, but those lessons have particularly stuck with me longer. He does exist.
