In a recent discussion with my sister-in-law, I was stumped. I said that Faith is the antithesis of Reason. She said, "No. They are not mutually exclusive. It is through reason that I have arrived upon my faith. I therefore believe that my faith is reasonable." But I think that faith is belief in the unknown. And if it is unknown, it is not knowledge. Therefor - how can it be reasonable? Your thoughts?
