Let's see what some Christian philosophers had to say about faith. I.M. Crombie wrote that theists, in order to express their belief, are bounded to use paradoxical statements. Some trust their cognitive faculties when they affirm the existence of God. For them, He is real and abstract at the same time, like memory. For others, He is something to speculate about.
As we can read in There Is a God, Anthony Flew, the founder of the new atheists “movement,” speculated long enough to change his mind about God. According to him, the fact that nature obeys laws points directly to God, as it does the fact that we are conscious, purpose driven beings. We are the product of billions of years of cumulative selection, or evolution, but this can’t in any way explain consciousness. We have the capacity of thinking in concepts and we are conscious of our ability to transcend matter, yet our brain is not very different from the one of an animal. We perceive ourselves as “selves,” but we can’t analyze the self because it’s not a mentalstate that can be observed or explained in scientific terms.
