The question of how much English should be used in international research universities is one with which I am extremely familiar. I would even say I am deeply puzzled by this trend. I am not certain what the correct answer should be.

That said, there are a few clear factors that determine the potential of a university to reach the highest levels of excellence. In the case of Harvard University, it was true that by the time of its tercentenary (300th anniversary of its founding) in 1936, Harvard had already achieved a reputation as a world-class institution. Harvard did not have the stature that it does today.

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.

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.

The rank of a university is similar to an index number say like the NASDAQ index. I don't understand how you can take an institution like Harvard, Stanford, or Michigan, and represent it by an index number. The concept makes no sense.

Research is an expression of faith in the possibility of progress. The drive that leads scholars to study a topic has to include the belief that new things can be discovered, that newer can be better, and that greater depth of understanding is achievable. Research, especially academic research, is a form of optimism about the human condition.

Public image is extremely important in American society and I observed personally that the Presidency of John F. Kennedy did much in the public mind for Harvard. Harvard was an excellent school before Kennedy, but Kennedy embodied a new vision for the United States: a leader who caught the world's imagination and that reflected on his alma mater, Harvard.
