“…while our senses can only ever bring us verifiable knowledge about how the world appears in time and space, our reason always strives to know more than appearances can show it. This tendency of reason to always know more is and was a good thing. It is why human kind is always curious, always progressing to greater and greater knowledge and accomplishments. But if not tempered by a respect for its limits and an understanding of its innate tendencies to overreach, reason can lead us into error and fanaticism.”
