Faust had the seniors in stitches during a humor-filled preamble. She called the Baccalaureate one of her “favorite events,” despite feeling daunted at imparting “the sober wisdom of age to the semi-sober impatience of youth.” The crowd roared its approval.

In four years on campus, the students helped to transform Harvard and the world around them as they strived for reinvention, inclusion, and innovation, Faust said. Their accomplishments included the student production “Black Magic,” a play about race and identity “that shattered precedent on the Loeb main stage.” They also turned out a range of prize-winning theses, including work on Lassa virus detection and a cultural history of the helicopter in Vietnam.

The class witnessed transformations in the form of a new concentration in Theater, Dance & Media, voluntary composting in the dorms, an end to backpack security checks at Lamont Library, and a shift in language and culture with the elimination off “House master” in favor of faculty dean. Students also saw “the entire campus agitate over sexual harassment and sexual assault,” Faust noted.

Building on her theme, Faust described three principles of transformation for the soon-to-be-grads to ponder. The first included a reminder that life “is not just about your passions; it is about your purpose.”

Listen to Faust’s address to graduating seniors

Faust’s recalled her freshman year in college, seeing future congressman John Lewis and other civil rights marchers beaten and tear-gassed while attempting to peacefully cross the Edmund Pettus Bridge in Selma, Ala.

“I felt a moral imperative to act — it was as if there was no other choice. Congressman Lewis calls it ‘making necessary trouble’ — a willingness to get in the way. I hear in your stories that same imperative.”

“See with fresh eyes,” Faust offered as her second principle, urging the students to draw deeper lessons from their studies in the arts and humanities and the sciences — patience, an appreciation for the value of listening, and a commitment to seeking out diverse perspectives.

A liberal arts education, said Faust, “enables us to see the world in order to understand how we can transform it.”

Finally, Faust told the seniors to “take this spirit of transformation with you”— a spirit linked to their professors and friends and the lessons of four years on campus — and to “keep the fire fueled by your education burning.”

Plummer Professor of Christian Morals and Pusey Minister in the Memorial Church Jonathan Walton encouraged listeners to think of Commencement as the beginning of a life enriched by the lessons and virtues instilled during college.

“Wisdom is more precious than silver or gold,” he said. “The common good outlasts individual accomplishments. And every grand idea that has ever pushed humanity forward began with a dream and faith put it into action.

“Be proud in recalling how far you have traveled in these four years, as well as the many obstacles that you have overcome,” he added. “Yet embrace humbly the infinite paths of possibility that are ahead of you.

The ceremony included songs, readings, prayers and blessings from a range of faiths and traditions. Graduates departed in a reflective mood.

Eden Girma said that she has come a long way since she first arrived on campus four years ago. A student in the Harvard-New England Conservatory dual degree program, Girma will head to London after graduation to study composition. She said she was grateful for Harvard’s resources and opportunities, but that her greatest transformation came “from the people I’ve been able to meet and interact with.”
