All of us rely on empiricism sometimes. When we were young, we learned not to touch the stove because we experience how awfully painful it was to touch it. This way of knowing things carries over into our adult lives. We experience their music. There is nothing wrong with a little empiricism.
Problems arise only when it becomes an exclusive philosophical position.
The Christian responds, of course, by pointing to the Bible. They have it on good authority that God, souls, etc. exist. They place their faith in scripture, rather than placing their faith in the non-existence of the supernatural. One of the central problems of our culture is that many people live their lives based on that second kind of faith. These assumptions are handed down to the majority of educators, who do their best to pass them on to our children.
