" Every perfection in this life has some imperfection mixed with it and no learning of ours is without some darkness. Humble knowledge of self is a surer path to God than the ardent pursuit of learning. Not that learning is to be considered evil, or knowledge, which is good in itself and so ordained by God; but a clean conscience and virtuous life ought always to be preferred. Many often err and accomplish little or nothing because they try to become learned rather than to live well.”

~ Thomas à Kempis (1380–1471); Imitation of Christ; Chapter 3 "
