For whatever reason, the idea that reasoned theories are only as valid s the experiments comes forth earlier--i.e. Aristotle's philosophy is shown as invalid. Perhaps a theologian reasons the following:
"We can only understand God if we understand the world He created for us. Let us go forth and examine it. The phiilosophers and scientists are not God, therefore they are falible."
Logical--and then this theologian becomes Pope, and can put his thoughts into church doctrine.
