Lewis, a notable and long-standing member of the Harvard faculty, worries about the state of American education — what do we want our students to learn? For him, too much emphasis is placed in course catalogs on intersectionality, and too little on a more canonical foundation of understanding. 

For Lewis, the campus protests are a mere symptom — we are "reaping what we have taught."

Harry Lewis is the Gordon McKay Research Professor of Computer Science at Harvard, and was the Dean of Harvard College for 8 years around the millennium.
