The scope of Alan Ryan’s two-volume historical work, On Politics: A History of Political Thought: From Herodotus to the Present (Liveright, $75.00) is as impressive as the subject matter. Three decades in the making, On Politics is one of the most ambitious and comprehensive histories of political philosophy in nearly a century. Rand, the former warden of New College at Oxford who teaches politics at Princeton, has produced both a history and an examination of human thought and behavior spanning three thousand years. On Politics traces the origins of political philosophy from the ancient Greeks to Machiavelli in Book I and from Hobbes to the present age in Book II. Publishers Weekly lauds Ryan for “. . . this absorbing and edifying read, which regularly reminds us of what modern citizens might gain from a deeper understanding of the roots of today's political ideals and loyalties.” Join one of the most influential political philosophers of our time as he looks to the past to provide insights to the present.
