A meditation on hope: Sherwin Nuland on TED.com

Surgeon and writer Sherwin Nuland meditates on the idea of hope -- the desire to become our better selves and make a better world. In a thoughtful 12 minutes, he explores the connection between "hope" and "change" -- a fitting talk to end this week full of both. (Recorded February 2003 in Monterey, California. Duration: 12:37.)
