Technology now facilitates civic involvement throughout the world, said the State Department’s Jared Cohen. In an essay for the Web site Huffington Post.com, Cohen reflected on the lessons of the AYM conference and concluded that “this new ability to connect [online] is leveling the playing field and breaking down previous age, gender, socioeconomic and circumstantial barriers to who can emerge as a leader, activist or grassroots agent for change.”

But the main reason for academics to be concerned about the time it takes to get a degree has to do with the barrier this represents to admission to the profession. The obstacles to entering the academic profession are now so well known that the students who brave them are already self-sorted before they apply to graduate school. A college student who has some interest in further education, but who is unsure whether she wants a career as a professor, is not going to risk investing eight or more years finding out. The result is a narrowing of the intellectual range and diversity of those entering the field, and a widening of the philosophical and attitudinal gap that separates academic from non-academic intellectuals. Students who go to graduate school already talk the talk, and they learn to walk the walk as well. There is less ferment from the bottom than is healthy in a field of intellectual inquiry. Liberalism needs conservatism, and orthodoxy needs heterodoxy, if only in order to keep on its toes.

The academic profession in some areas is not reproducing itself so much as cloning itself. If it were easier and cheaper to get in and out of the doctoral motel, the disciplines would have a chance to get oxygenated by people who are much less invested in their paradigms.
