This article is an attempt to understand the increasing profile of complexity theory as a geography of dissemination. In the first part I suggest that complexity theory, itself a rhetorical hybrid, takes on new meanings as it circulates in and through a number of actor-networks and, specifically, global science, global business and global New Age. As complexity theory circulates in these networks, so it encounters new conditions, which generate new hybrid theoretical forms. In the second part of the article, I (...) consider how complexity theory might be interpreted as the emergence of a new structure of feeling in Euro-American societies, which frames the future as open and full of productivity. The conclusion offers some words of warning. (shrink)
