Hope. It’s a substance in short supply in 2020, yet more exquisitely important than ever before as we face unparalleled challenges as a species. We conclude this year’s Festival with a keynote address from esteemed thought leader Thomas Homer-Dixon, renowned for bestselling titles such as The Upside of Down: Catastrophe, Creativity, and the Renewal of Civilization, The Ingenuity Gap: Can We Solve the Problems of the Future and, now, Commanding Hope: The Power We Have to Renew a World in Peril.

In this extraordinary work, Homer-Dixon delves into complexity science, and how societies can evolve, to show we can shift human civilization onto a decisively new path—if we mobilize our imaginations and collective values. Commanding Hope marshals a fascinating, accessible argument for, ultimately, a renewed hope in a positive future for everyone on Earth.
