" Reason excludes faith," Alessandro responded, watching the blood-red mite as it made a dash for the rim. " It's deliberately limited. It won't function with the materials of religion. You can come close to proving the existence of God by reason, but you can't do it absolutely. That's because you can't do anything absolutely by reason. That's because reason depends on postulates. Postulates defy proof and yet they are essential to reason. God is a postulate. I don't think God is interested in the verification of His existence, and, therefore, neither am I. Anyway, I have professional reasons to believe. Nature and art pivot faithfully around God. Even dogs know that. "
