The Ogilvy & Inspire Lecture is an annual showcase of inspirational ideas. In the past, we’ve challenged Cannes audiences to think differently about education, values, public spaces, and the cosmos. This year, Monica Lewinsky, the oft-described “Patient Zero” of online shaming, calls for an end to cyberbullying and urges us to mend our broken social discourse. Ms. Lewinsky will ask us to resist the impulse to judge and will issue a clarion call for fostering compassion—both online and off.
