Snake that Swallowed Its Tail [PDF ebook] 

Liberal values are the hallmark of a civilised society. Yet they depend on an optimistic view of the human condition, Stripped of this essential ingredient, liberalism has become a hollowed-out abstraction. Tracing its effects through the media, politics and the public services, the author argues that hollowed-out liberalism has helped to produce our present discontent. Unless we stop boasting about our values and try to recover their essence, liberal society will be crushed in the coils of its own contradictions.
