The application of reason to these fields is of course enormously beneficial, but you cannot argue, for example, from any particular reason, why 2 + 2 = 4. Or why beauty is preferable to ugliness. Or why it is wrong to torture someone just for the fun of it.
Therefore I think some of the threads in this section are misguided - ontological arguments, cosmological arguments, arguments about necessity and First Cause..... these are all interesting exercises, but they are ultimately exercises in futility.
Faith is belief. It is hope. Brought about by the intuition that all this cannot be meaningless....
iblees used reasoning when he was asked to bow down to adam and he was cast out of heaven ( so its said)
Godel proved thru formal mathematics that there are certain truths within a system which cannot be proved....so thats the extent of reasoning alone
I think when one completely exhausts their reasoning what they are left with is Faith, and that is true Faith when you have no reason left for it...and since you don't have any reasoning for it then its not acquired by you, but it comes from something that is beyond you.
