"Atheists and agnostics ask for this kind of "proof" for God, but are not alone in holding to strong rationalism. Many Christians claim that their arguments for faith are so strong that all who reject them are simply closing their minds to the truth out of fear or stubbornness.4 Despite all the books calling Christians to provide proofs for their beliefs, you won't see philosophers doing so, not even the most atheistic. The great majority think that strong rationalism is nearly impossible to defend.5 To begin with, it can't live up to its own standards. How could you empirically prove that no one should believe something without empirical proof?"
