It seems odd that in a knowledge economy where intellectual and knowledge work have become so important, universities are struggling as never before for economic survival. How do we explain the fact that most parents who have themselves experienced a university education want one for their children, yet do not rush to defend universities in the public debate about their futures and exert neither themselves nor their pocketbooks to ensure their survival？ Perhaps we have, collectively, an uneasiness with the kind of education that universities provide but recognize it, for the moment, as a short cut to economic advancement and therefore bear with it.
As the world moves towards a state of globalization, universities have to come to terms with what that might mean for their organization and curricula. As the power of the nation state wanes and borders become less relevant, they need also to ponder how to produce graduates who engage as global citizens and how they, as institutions, remain part of an international community of scholars. As the private sector offers more in the way of higher education, universities need to understand the distinct role it is possible for them to fulfill. And as the commercialization of knowledge becomes ever more rampant, we all need to contemplate the possibility that universities can no longer be sites of disinterested research.
Many universities are grappling with these issues, but it is important that all who value their continued existence also engage in the debate. Only in the common search for solutions will we, come to understand how precious is the resource in which we have invested so much as a country. How easy it would be for such a valuable resource to be almost irreparably damaged by our neglect.
Universities must never forget that it is by the attributes of those who pass through their portals that they will be valued. Perhaps it is time to re-assess the nature of what we offer and we can begin by looking at what others have suggested as our new role in such uncertain times.
