Carson's central thesis was that the most important question anyone can ask is: who am I, really? He noted that we often present ourselves as simply the sum of our social roles, titles, degrees, and accomplishments. We are our reputations, our duties as children, spouses, parents, and friends. But Carson argued that these are just superficial expressions of identity, things that can be changed or abandoned when they conflict with some deeply rooted idea of the person we want to be. He drew a parallel to his decades-long study of Martin Luther King Jr., observing that even after detailing every aspect of King's public and private life, the essential biographical question remained unanswered. Carson urged graduates to engage in serious self-examination, especially during this period of changing identities from student to whatever comes next.
