Having been a student of philosophy way back when, I was drawn to the title of G. John Ikenberry’s newly published book Liberal Leviathan: The Origins, Crisis, and Transformation of the American World Order, with its echo of the great 17th century English philosopher Thomas Hobbes. So I was among the fifty or so local residents who turned up to hear Ikenberry discuss his prescription for the future at Labyrinth Books on Wednesday, April 13.
