The sacrifice pillar of social order and , ultimately , the world, is one of the central concerns of De Maistre . Life emerges from the blood circulating through the body . The man is both flesh and spirit, body and soul. Meat, sensitive principle in man , is the cause of his guilt, and it can not be washed more than blood . Salvation by blood : this is the principle that , as De Maistre , behind every sacrifice . Hence the universality of a practice that today devoid of sacredness and splendor that were of the age , is still valid in modern societies.
