From the preface of Mark Twain's Personal Recollections of Joan of Arc:
To arrive at a just estimate of a renowned man’s character one must judge it by the standards of his time, not ours. Judged by the standards of one century, the noblest characters of an earlier one lose much of their lustre; judged by the standards of today, there is probably no illustrious man of four or five centuries ago whose character could meet the test at all points. But the character of Joan of Arc is unique. It can be measured by the standards of all times without misgiving or apprehension as to the result. Judged by any of them, judged by all of them, it is still flawless, it is still ideally perfect; it still occupies the loftiest place possible to human attainment, a loftier one than has been reached by any other mere mortal.
She was perhaps the only entirely unselfish person whose name has a place in profane history. No vestige or suggestion of self-seeking can be found in any word or deed of hers. When she had rescued her King from his vagabondage, and set his crown upon his head, she was offered rewards and honours, but she refused them all, and would take nothing. All she would take for herself - if the King would grant it - was leave to go back to her village home, and tend her sheep again, and feel her mother’s arms about her, and be her housemaid and helper. The selfishness of this unspoiled general of victorious armies, companion of princes, and idol of an applauding and grateful nation, reached but that far and no farther.
