That success was owing to a very simple artifice; it was only to tell my story in a quiet and truthful manner, without even avoiding the facts which told against me. It is simple secret that many men do not know, because the larger portion of humankind is composed of cowards; a man who always tells the truth must be possessed of great moral courage. Experience has taught me that truth is a talisman, the charm of which never fails in its effect, provided it is not wasted upon unworthy people, and I believe that a guilty man, who candidly speaks the truth to his judge, has a better chance of being acquitted, than the innocent man who hesitates and evades true statements. Of course the speaker must be young, or at least in the prime of manhood; for an old man finds the whole of nature combined against him.
