On its publication in 1957, The Poverty of Historicism was hailed by Arthur Koestler as ''probably the only book published this year which will outlive the century.''

A devastating criticism of fixed and predictable laws in history, Popper dedicated the book to all those ''who fell victim to the fascist and communist belief in Inexorable Laws of Historical Destiny.'' Short and beautifully written, it has inspired generations of readers, intellectuals and policy makers. One of the most important books on the social sciences since the Second World War, it is a searing insight into the ideas of this great thinker.
