"If I were to try to read, much less answer, all the attacks made on me, this shop might as well be closed for any other business. I do the very best I know how -- the very best I can. And I mean to keep on doing it to the end. If the end brings me out all right, what is said against me will not amount to anything. If the end brings me out all wrong, ten angels swearing I was right would make no difference."
"In our world of big names, curiously, our true heroes tend to be anonymous. In this life of illusion and quasi-illusion, the person of solid virtues who can be admired for something more substantial than his well-knownness often proves to be the unsung hero: the teacher, the nurse, the mother, the honest cop, the hard worker at lonely, underpaid, unglamorous, unpublicized jobs."
