Yet now, nearly four centuries later, we find ourselves in a challenging historical moment.How do we "enlarge" our graduates in a way that benefits others as well?Shepard spoke of enlarging "toward" -- toward, as he put it, "the country and the good of it."Are we succeeding in educating students oriented toward the betterment of others?Or have we all become so caught up in individual and personal achievements, opportunities, and appearancesthat we risk forgetting our interdependence, our responsibilities to one another and to the institutions meant to promote the common good?This is the era of the selfie -- and the selfie stick.Now don't get me wrong: There is much to love about selfies, and two years ago in my Baccalaureate addressI concluded by urging the graduates to send such pictures along so we could keep up with them and their post-Harvard lives.But think for a moment about the implications of a society that goes through life taking its own picture.That seems to me a quite literal embodiment of "self-regarding" -- a term not often used as a compliment.
