Somewhat later – I have a scrap of paper here telling me to look at Torgovnick, p. 40, on carnival, and that the quotation is good. When I get to a location where the Torgovnick book is available (I am many miles from it now) I will look at that page and post it here or somewhere else relevant.
The scrap of paper also says: the question is what the rules of exchange are between the modern West, the postmodern West, and their versions of the primitive. What the rules of exchange are. We will all think about this.
