Some months before Graeber's sudden death I finished his briliant anthropological work on debt. It will be one of the canon works of humanities when human being starts to think twice about economy. Graeber enlightened us as to the dark side of civilization. He revealed our dogmatic approaches toward sociology and history. There are many illuminations on slavery, family, money, government, colonization, militarism and etc in DEBT. He taught us anthropology is a libertarian science.
