As a beneficiary of the Welfare State and the Permissive Society – to name just two of their life-enhancing achievements – I owe an enormous debt to the liberal intelligentsia who, in the teeth of opposition from the Old Gang, brought them to pass. But who were these irreverent shock troops and what motivated them? The answer is given by one of their standard bearers, Noel Annan (1916‒2000), in his dazzling group portrait Our Age (1990), which is not only a joy to read but also a wonderful crib for anyone studying the social history of Britain from the 1920s to the 1960s.
