Know verily that Knowledge is of two kinds: Divine and Satanic. The one welleth out from the fountain of divine inspiration; the other is but a reflection of vain and obscure thoughts. The source of the former is God Himself; the motive-force of the latter the whisperings of selfish desire. The one is guided by the principle: "Fear ye God; God will teach you;" the other is but a confirmation of the truth: "Knowledge is the most grievous veil between man and his Creator." The former bringeth forth the fruit of patience, of longing desire, of true understanding, and love; whilst the latter can yield naught but arrogance, vainglory and conceit. (Baha'u'llah, The Kitab-i-Iqan)
