I read this more than five years ago. It is scholarly but well written. When I finished it, I wondered how practical it would be. In the last five years, I have thought about it several times. I cannot say that about 90% of the books I have read.
I believe it is a good example of "history of ideas" literature. It is a deconstruction of the notion of economics and commerce. By focusing on the narrow subject of gift giving, it opens the window to a critical understanding of common ideas like "interest," "usury," and "economic community." After all, what makes up a global economy? How do people bind themselves to "beliefs" that enable cooperation.
The book is not prescriptive. Instead, it is provocative to the extent that it challenges assumptions. I recommend it to the reader who is looking for an intellectual escape into the historically possible.
