A quote from his speech about his life at Harvard:
Confidence in progress has now been replaced by postulation of change.
Progress is achieved and can be welcomed, but change just happens and
must be adjusted to. “Adjusting to change” is now the unofficial motto
of Harvard, mutabilitas instead of veritas. To adjust, the
new Harvard must avoid adherence to any principle that does not change,
even liberal principle. Yet in fact it has three principles: diversity,
choice, and equality. To respect change, diversity must serve to
overcome stereotypes, though stereotypes are necessary to diversity. How
else is a Midwesterner diverse if he is not a hayseed? And diversity of
opinion cannot be tolerated when it might hinder change.
