Soren Kierkegaard on Faith and Reason

There is only one proof – that of faith. It is impossible for a person to 
hold back his conviction and push ahead with reasons. If I actually have a

firm conviction, then it is higher than reasons; it is actually the 
conviction that sustains the reasons, not the reasons which sustain the 
conviction. “Reasons” can lay an egg no more than a rooster can, at most a

wind egg, and no matter how much intercourse they have with each other
they 
never beget or bear a conviction. A conviction arises elsewhere.
