Can Harvard dedicate its intellect to improving the lives of people who will never even hear its name? Let me make a request of the deans and the professors – the intellectual leaders here at Harvard: As you hire new faculty, award tenure, review curriculum, and determine degree requirements, please ask yourselves:Should our best minds be dedicated to solving our biggest problems?Should Harvard encourage its faculty to take on the world’s worst inequities? Should Harvard students learn about the depth of global poverty … the prevalence of world hunger … the scarcity of clean water…the girls kept out of school … the children who die from diseases we can cure?Should the world’s most privileged people learn about the lives of theworld’s least privileged? These are not rhetorical questions – you will answer with your mother, who was filled with pride the day I was admitted here –never stopped pressing me to do more for few days before my wedding, she hosted a bridal event, at which she read aloud a letter about marriage that she had written to mother was very ill with cancer at the time, but she saw one more opportunity to deliver her message, and at the close of the letter she said: ―From those to whom much is given, much is expected.‖ When you consider what those of us here in this Yard have been given –in talent, privilege, and opportunity – there is almost no limit to what the world hasa right to expect from line with the promise of this age, I want to exhort each of the graduates here to take on an issue – a plex problem, a deep inequity, and bee a specialist on
