It is a biographical book. The life must be lived before the history of a life can be written, hence it is not my life that I am writing. Having been attacked in early youth by an abominable moral malady, I relate what has happened to me during three years. If I were the only victim of this disease, I would say nothing, but as there are many others who suffer from the same evil, I write for them, although I am not sure that they will pay any attention to it; in case my warning is unheeded, I shall still have derived this benefit from my words in having cured myself, and, like the fox caught in a trap, I shall have devoured my captive foot.
