This article proposes a framework within which the question as to the purposes of open universities should be examined. It argues that the question has become submerged over time through the establishment of so many open universities that have become natural elements in a higher education landscape rather than remaining radical and innovative institutions. The article looks at a number of innovative distance teaching higher education institutions from the nineteenth century through to the contemporary period, and examines case studies in a wide international range. The outcome of the argument is that open universities should articulate their purposes within a discourse of development, and engage with the ethical and political questions as to how development is understood and advanced.
