Bestselling author, media pioneer, and curator of TED for over twenty years, Chris Anderson visits Google to discuss his book "Infectious Generosity: The Ultimate Idea Worth Spreading." The book explores one of humankind's defining but overlooked impulses, and how we can super-charge its potential to build a hopeful future.

Let's face it: Recent years have been tough on optimists. Hopes that the Internet might bring people together have been crushed by the ills of social media. Is there a way back?

As the head of TED, Chris Anderson has had a ringside view of the world's boldest thinkers sharing their most uplifting ideas. Inspired by them, he believes that it's within our grasp to turn outrage back into optimism. It all comes down to reimagining one of the most fundamental human virtues: generosity. What if generosity could become infectious generosity?

Anderson's book offers a playbook for how to embark on our own generous acts—whether gifts of money, time, talent, connection, or kindness—and to prime them to have self-replicating, even world-changing, impact.
