In the second of his “theological orations,” Gregory Nazianzen catalogs the impenetrable mysteries of creation: “How is it,” he asks, “that the earth stands solid and unswerving?  On what is it supported?  What is it that props it up, and on what does that rest?”

And then: “For indeed reason has nothing to lean upon, but only the Will of God.”

Patristic anti-foundationalism.
