Not in the text, but added by many sources is the sentence: "It will confound your enemies and astound your friends." Compare this line to the advice attributed to Henry Wotton (1568 - 1639) to a young diplomat "to tell the truth, and so puzzle and confound his enemies." E.g., Vol 24, Encyclopedia Britannica of Arts, Sciences, and General Literature, page 721 https://books.google.com/books?id=_GlJAAAAYAAJ&pg=PA721&lpg=PA721&dq=truth+wotton+confound+advice&source=bl&ots=-cGk3UDLLj&sig=ltOR1xtI9WFic1JWKiFmIZ8Yce0&hl=en&sa=X&ved=0ahUKEwjVkZCsj-jRAhXCyFQKHTmsCkAQ6AEIODAG#v=onepage&q=truth%20wotton%20confound%20advice&f=false (9th Ed. 1894)

“It is wonderful, the power of a faith like that, that can make multitudes upon multitudes of the old and weak and the young and frail enter without hesitation or complaint upon such incredible journeys and endure the resultant miseries without repining. It is done in love, or it is done in fear; I do not know which it is. No matter what the impulse is, the act born of it is beyond imagination marvelous to our kind of people, the cold whites.”

“These wisdoms are for the luring of youth toward high moral altitudes. The author did not gather them from practice, but from observation. To be good is noble; but to show others how to be good is nobler and no trouble.”

“She had run down and down and down, and had at last reached a point where medicines no longer had any helpful effect upon her. I said I knew I could put her upon her feet in a week. It brightened her up, it filled her with hope, and she said she would do everything I told her to do. So I said she must stop swearing and drinking, and smoking and eating for four days, and then she would be all right again. And it would have happened just so, I know it; but she said she could not stop swearing, and smoking, and drinking, because she had never done those things. So there it was. She had neglected her habits, and hadn’t any. Now that they would have come good, there were none in stock. She had nothing to fall back on. She was a sinking vessel, with no freight in her to throw overboard and lighten ship withal.”
