 When the Residential College opened in 1967 Cohen became a full-time member of its faculty, and his appointment was shifted from the Department of Philosophy to the Residential College, where he remains the only one of that founding group serving as an active member of the Michigan faculty.In 1998 anonymous donations totaling some $13,000 were made to the university to name a reading room in the Residential College in Cohen's honor.This was done; a plaque honoring him was placed.
