Since the turn of the millennium, the major development agencies have been promoting “knowledge for development,” “ICT for development,” or the “knowledge economy” as new paradigms to prompt development in less-developed countries. These paradigms display an unconditional trust in the power of Western technology and scientific knowledge to trigger development—they taste of epistemic and technological determinism.

The genealogy shows, first, that knowledge and technology have always been integrally part of the very “development” idea since this idea was shaped during enlightenment. Second, while the genealogy reveals that epistemic and technological determinism were embedded in the development idea from the very beginning, it also illustrates that the determinism has always been challenged by critical voices.
