He has written an exceedingly clever and disturbing book on important issues, all that he writes is alive and much of what he says, even when it seems perversely provocative, turns out to be penetrating and serious.” —Isaiah Berlin, 20th Century“One of the most thoughtful products of the political dialogues of the London School of Economics since the great days of Tawney, Dalton, Wallas and Hobhouse. Its sobriety, liberal spirit and toughness of mind are rare qualities in any political work.” —Edward Shils, Guardian
