"Preface: I am going to make, at the beginning of my book, certain apologies and explanations, which would have como more appropriately at the end. But custom, which prescribes a Preface, proscribes an Epilogue, thus leaving me no alternative but to cry "peccabo", and impudently demand absolution for a prospective offence. Neverthless, I hope that my preliminary confessions may take the wind out my critics´ sails".
