"The Agnostic one who asserts... that there are limits to the sphere of human intelligence. He asserts further... that those limits are such as to exclude at least what Lewes [George Henry Lewes (1817-1878) British philosopher] called "metempirics" knowledge. But he goes further, and asserts, in opposition to theologians, that theology lies within this forbidden sphere... The Gnostic holds that our reason can, in some sense, transcend the narrow limits of experience. He holds that we can attain truths not capable of verification, and not needing verification, by actual experiment or observation."
