I came across this quote:

isn’t the university primarily a place for the unfettered expression of ideas? The answer is no. The university is primarily a place for teaching and research. The unfettered expression of ideas is a cornerstone of liberal democracy; it is a prime political value. It is not, however, an academic value

here by Stanley Fish.

How does teaching and research categorically exclude the expression of ideas? I just can’t make it work in my head. Can’t make it work at all.
