Niall Ferguson is one of the world's most renowned historians. He is Senior Fellow at the Hoover Institution, Stanford University, and a Visiting Professor at Tsinghua University, Beijing. His many awards include the Benjamin Franklin Prize for Public Service (2010), the Hayek Prize for Lifetime Achievement (2012) and the Ludwig Erhard Prize for Economic Journalism (2013).
In his new book, "The Square and the Tower: Networks and Power, from the Freemasons to Facebook," Ferguson points out that though the 21st century has been hailed as the Age of Networks, networks have always been with us.
Throughout history, hierarchies housed in high towers have claimed to rule, but often real power has resided in the networks in the town square below. For it is networks that tend to innovate. And it is through networks that revolutionary ideas can contagiously spread.
