Barack Obama said this quote

It’s not just absolute power that the Founders sought to prevent. Implicit in its structure, in the very idea of ordered liberty, was a rejection of absolute truth, the infallibility of any idea or ideology or theology or “ism,” any tyrannical consistency that might lock future generations into a single, unalterable course, or drive both majorities and minorities into the cruelties of the Inquisition, the pogrom, the gulag, or the jihad. The Founders may have trusted in God, but true to the Enlightenment spirit, they also trusted in the minds and senses that God had given them. They were suspicious of abstraction and liked asking questions, which is why at every turn in our early history theory yielded to fact and necessity.
