If you’re having trouble sleeping, try attending a Harvard section. This near-ubiquitous course component is so egregiously slow and perfunctory it could serve as a callous lullaby. Intimate and discourseful engagements are hard to come by in lectures — this is an unfortunate byproduct of the need to present information to a large audience. Sections are meant to initiate that exact engagement, through close interaction with both the teaching team and one’s fellow classmates.
