The book the reader has now before his eyes - from one end to the other, in its whole and in its details, whatever the omissions, the exceptions, or the faults - is the march from evil to good, from injustice to justice, from the false to the true, from night to day, from appetite to conscience, from rottenness to life, from brutality to duty, from Hell to Heaven, from nothingness to God. Starting point: matter; goal: the soul. Hydra at the beginning, angel at the end.
