New Power explores how influence, leadership, and engagement have evolved in the digital age. The authors contrast "old power"—top-down, closed, and leader-driven—with "new power"—open, participatory, and crowd-sourced. Through case studies like #MeToo, Airbnb, and TED, they show how modern movements and brands leverage community and transparency. The book offers tools for leaders, activists, and entrepreneurs to harness this shift effectively. Branson and other innovators have praised New Power for its relevance in today’s hyperconnected world, where collaboration and authenticity often matter more than hierarchy or control.

In The Better Angels of Our Nature, cognitive scientist Steven Pinker argues that, contrary to popular belief, violence has declined significantly over human history. Drawing on data from psychology, history, and political science, Pinker examines how societal changes—such as the spread of literacy, trade, and centralized governance—have contributed to a more peaceful world. He identifies forces like empathy, reason, and moral progress as "better angels" guiding human behavior. Though controversial, the book provides a compelling, data-driven narrative that challenges pessimistic views of human nature and makes a bold case for the progress of civilization over the centuries.

In The Constitution of Knowledge, Jonathan Rauch defends the epistemic institutions—science, journalism, academia—that uphold truth in democratic societies. He explores how norms like open debate, peer review, and fact-checking serve as a “constitution” governing the marketplace of ideas.

Blending political philosophy, history, and media studies, the book is both a defense and a roadmap for safeguarding truth in a digital age. It's an essential read for anyone concerned about democracy, truth, and the future of civil discourse.
