“Sacrificial destruction implies giving something that is to be repaid. All forms of North-West American and North-East Asian potlatch contain this element of destruction. It is not simply to show power and wealth and unselfishness that a man puts his slaves to death, burns his precious oil, throws coppers into the sea, and sets his house on fire. In doing this he is also sacrificing to the gods and spirits, who appear incarnate in the men who are at once their namesakes and ritual allies.”
