. . . the scholars at the conference invariably assumed that "gifts" do not really exist: Scratch deep enough behind any human action, and you'll always discover some selfish, calculating strategy. Even more oddly, they assumed that this selfish strategy was always, necessarily, the real truth of the matter; that it was more real somehow than any other motive in which it might be entangled. It was as if to be scientific, to be "objective" meant to be completely cynical.
. . . Economists and Christian theologians agree that if one takes pleasure in an act of generosity, it is somehow less generous . . . To counteract this very perverse logic, Mauss emphasized the "pleasure" and "joy" of giving: In traditional societies, there was not assumed to be any contradiction between what we would call self-interest (a phrase that, he noted, could not even be translated into most human languages) and concern for others; the whole point of the traditional gift is that it furthers both at the same time.
