To be proud of learning is the greatest ignorance. — Jeremy Taylor. English cleric (1613–1667) , Bishop Taylor. US Catholic bishop
He that speaketh against his own reason speaks against his own conscience, and therefore it is certain that no man serves God with a good conscience who serves him against his reason.
It is impossible to make people understand their ignorance; for it requires knowledge to perceive it and therefore he that can perceive it hath it not.
