God in the Dock

by C.S. Lewis

Whatever experiences we may have, we shall not regard them as miraculous if we already hold a philosophy which excludes the supernatural.

Experience by itself proves nothing. If a man doubts whether he is dreaming or waking, no experiment can solve his doubt, since every experiment may itself be part of the dream. Experience proves this, or that, or nothing, according to the preconceptions we bring to it.
