In the 15 years since its inception, Wikipedia has become as much a global community as a business venture — a living organism with a mission statement to make “the sum of all human knowledge available to every person in the world.” And a conversation with co-founder Jimmy Wales — one of the architects of that philosophy and the world-changing project that has grown up around it — is full of surprises. What Wikipedia is learning has resonance for our wider public life — about the imperfect but gratifying work of navigating truth amidst difference, ongoing learning, and dynamic belonging.
