So what if faith is quixotic and mad?

Is there anything at all to be said for fideism? Guess it depends on what you think of Don Quixote.

Faith is indeed quixotic. It is absurd. Let us admit it. Let us concede everything!

Concede everything, and continue believing anyway. That drives many atheists right up the wall. I'm still trying to understand why such a smart and sane guy as Martin Gardner could "admit that faith is a kind of madness" and still embrace it.
