Faith does not have anything to do with logic or philosophic arguments.
Yet another example of how empiricism misses the forest for the trees. Faith has everything to do with logic and philosophic arguments; those are the reasons why one believes what one believes. Faith is simply a conclusion one reaches about things which are beyond empirical proof. Because you can't see them and put them into a test tube and observe them, it doesn't mean they don't exist.
"You may tear apart the baby's rattle and see what makes the noise inside, but there is a veil covering the unseen world which not the strongest man, nor even the united strength of all the strongest men that ever lived, could tear apart. Only faith, fancy, poetry, love, romance, can push aside that curtain and view and picture the supernal beauty and glory beyond. Is it all real? Ah, VIRGINIA, in all this world there is nothing else real and abiding. "
