Often, to get something done that really matters, we need to work with people we don’t agree with, like, or trust.

Instead, he provides a groundbreaking approach that embraces discord, experimentation, and genuine cocreation.

Using new case studies, a discussion guide, and frameworks for navigating permanent plurality in our polarized times, Kahane offers essential tools for transforming conflict into positive change.
