Asian colleges would do well to use a broad range of criteria in selecting students and move beyond the unproductive "examination hell. "

I would not say that Harvard possesses any sort of absolute dominance. And I personally do not take the rankings of schools all that seriously. However, I think that Harvard's global visibility increased significantly in the 1930s and 1940s and that the new commitment to excellence at Harvard spread to other institutions.

Harvard introduced the now famous ad hoc system whereby a group of experts in the field of the faculty member to be promoted are consulted concerning the stature of that scholar. This move made the opinion within the field, rather than the clubby relationship within the department, the determining factor in the promotion of professors.

Never underestimate the difficulty of changing false beliefs by facts

There are, however, many challenges to Asian universities. First, academic freedom, in all senses, is much more critical to the success of a university than how much money is spent on infrastructure or on hiring big names. Faculty need to have the space to pursue the research that they are passionate about and the also need to have the freedom to express their opinions in the university, and in the society as a whole.

There seems also to be a tremendous risk to indigenous cultures if we insist that all scholarship be conducted in English. We are, for example, dealing with ancient and very highly-developed cultures in Korea, Japan, China and the Middle East. What is the impact on cultural and scholarly vitality forcing everyone to do their work in English? I do not have an answer, but this issue has been very much on my mind.

There are many in East Asia who simply judge students on the basis of national tests. The top universities in the United States do not do that, and for good reason. We need a careful process for admissions that take all sorts of factors into account: different intellectual strengths, artistic expression, economic standing, social background, ethnicity, regional representation and designs a class as a balanced whole.
