“Narrow” is an adjective the academy should not shun but embrace, for if academic activity cannot be narrowly defined, it loses its shape and becomes indistinguishable from political rallies and partisan exhortation. This of course is what the [Israel] boycotters want. [Extremely broad definitions] do not enhance the academic enterprise or add a heroic gloss to the concept of academic freedom; rather they destroy both by emptying them of any specific content.
