The Kaplen JCC on the Palisades in Tenafly is registering for its JCC University, an adult education program that offers participants the opportunity to rekindle past passions, ignite new interests, meet new people, and stay involved in the developments that shape today’s world. Top professors and experts talk about topics including literature, art, film, science, psychology, and politics.

Enrollment is open for a four-session winter term. On January 25, Professor A.
