The man who knows how to lead one of his brothers towards what he has known may one day be saved by that very brother. People bring about their own undoing through their tongues. If one tries to navigate unknown waters one runs the risk of shipwreck. Leave him in error who loves his error. Every man is rich in excuses to safeguard his prejudices, his instincts, and his opinions.
Love is one thing, knowledge is another.
An answer brings no illumination unless the question has matured to a point where it gives rise to this answer which thus becomes its fruit. Therefore learn how to put a question. Understanding develops by degrees. There grows no wheat where there is no grain. The only thing that is humiliating is helplessness.
