This volume signals reinvigoration of Russell the public campaigner. The title of the volume is taken from one of his most famous and eloquent short essays and probably the best known of his many broadcasts for the BBC. Man's Peril 1954-55 not only captures the essence of Russell's thinking about nuclear weapons and the Cold War in the mid 1950s, but its extraordinary impact which served to jolt him into political protest once again. The activism of which we glimpse the initial stirrings in this volume continued in various guises more or less without interruption until his death. Russell later became involved with pressure group politics of the Campaign for Nuclear Disarmament and the civil disobedience tactics of the Committee of 00. In the writings assembled in this volume, however, he is looking towards the non-aligned states and world scientific opinion as possible brokers of détente. Although Russell was becoming increasingly immersed in work for peace, this was not to find him reminiscing about his peace about peace campaigning during the First World War, defending "History As an Art", and attacking the obscurantism of obscenity legislation and the opponents of birth control.
