In the past, American colleges and universities were created to serve a dual purpose to advance learning and to offer a chance to become familiar with bodies of knowledge already discovered to those who wished it. To create and to impart, these were the distinctive features of American higher education prior to the most recent, disorderly decades of the twentieth century. The successful institution of higher learning had never been one whose mission could be defined in terms of providing vocational skills or as a strategy for resolving societal problems. In a subtle way Americans believed higher education to be useful, but not necessarily of immediate use.
