" The conviction reigns that it is only through the sacrifices and accomplishments of the ancestors that the tribe exists--and that one has to pay them back with sacrifices and accomplishments; one thus recognizes a debt that constantly grows greater, since these forebears never cease, in their continued existence as powerful spirits, to accord the tribe new advantages and new strength. "

― Friedrich Nietzsche , On the Genealogy of Morals / Ecce Homo
