“Although wrongs have been done to me I live in hopes.”
As quoted in The West : Who is the Savage? (2001) PBS http://www.pbs.org/weta/thewest/program/episodes/four/whois.htm
Context: Although wrongs have been done to me I live in hopes. I have not got two hearts. … Now we are together again to make peace. My shame is as big as the earth, although I will do what my friends advise me to do. I once thought that I was the only man who persevered to be the friend of the white man, but since they have come and cleaned out our lodges, horses, and everything else, it is hard for me to believe the white man anymore.

Letter to Edward Dickens (26 September 1868), published in The Selected Letters of Charles Dickens http://books.google.com.br/books?id=NJH1g1i4gnIC&printsec=frontcover&hl=pt-BR#v=onepage&q&f=false, Edited by Jenny Hartley
Context: I put a New Testament among your books, for the very same reasons, and with the very same hopes that made me write an easy account of it for you, when you were a little child; because it is the best book that ever was or will be known in the world, and because it teaches you the best lessons by which any human creature who tries to be truthful and faithful to duty can possibly be guided. As your brothers have gone away, one by one, I have written to each such words as I am now writing to you, and have entreated them all to guide themselves by this book, putting aside the interpretations and inventions of men.
