To understand the rise of what he calls ‘the revolutionary temper’, Darnton draws on a lifetime’s study of pamphlets, books, underground newsletters, songs and public performances, exploring Paris as an information society not unlike our own. Its news circuits were centred in cafes and market-places, on park benches, and under the Palais-Royal’s Tree of Cracow, a favourite gathering-place for gossips. He shows how the events of forty years – from disastrous treaties, official corruption and royal scandal to thrilling hot-air balloon ascents and a new conception of the nation – all entered the collective consciousness of ordinary Parisians.
