The Collected Papers 28 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, its extraordinary impact 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. In the writings assembled in this volume, however, he is looking towards the non-aligned states and world scientific opinion as possible brokers of detente. (The volume includes Russell's famous public statement, the declaration of scientists known as 'The Russell Einstein Manifesto'.) Although Russell was becoming increasingly immersed in work for peace, this was not to the exclusion of all other interests. For example, here we find also him reminiscing about his 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.
