Since the onslaught of neoliberal triumphalism from the 1980s onwards, critical development theory increasingly found itself in a sort of academic twilight zone. With few exceptions development research became characterised by an emphasis on empiricism, quantitative methodologies and policy-oriented project evaluations. Interpreting Third World problems in terms of the inner logic and shifting contradictions of a globalising capitalism was limited to those situated in the critical theory twilight zone.

The current article focuses specifically on a number of challenges which have to be faced by critical theory when leaving the twilight zone.
