All the great theologians in the Catholic Church have denounced reason as the light furnished by the enemy of mankind -- as the road that leads to perdition. All the great Protestant theologians, from Luther to the orthodox clergy of our time, have been the enemies of reason. All orthodox churches of all ages have been the enemies of science. They attacked the astronomers as though they were criminals -- the geologists as though they were assassins. They regarded physicians as the enemies of God -- as men who were trying to defeat the decrees of Providence. The biologists, the anthropologists, the archaeologists, the readers of ancient inscriptions, the delvers in buried cities, were all hated by the theologians. They were afraid that these men might find something inconsistent with the Bible.
