“Whether it is the best of times or worst of times, you will need over the decades ahead to find—in your work, your family life, your civic engagement—that special balance of reason and passion that we treasure at Vanderbilt,” Chancellor Nicholas S. Zeppos told the Class of 2015 during Commencement on May 8. The ceremony capped two days of activities for graduates and their guests, including the Senior Day speech by Walter Isaacson, author and former chairman and CEO of CNN. In all, the university awarded 1,644 undergraduate and 2,212 graduate and professional degrees this year.
