Book excerpt: During the 1950s and 1960s, a generation of poets appeared who would eschew the restrained manner of 'movement' poets such as Philip Larkin, a generation who would, in the words of the introduction to A. Alvarez's classic anthology 'The New Poetry', take poetry 'beyond the gentility principle'. This was the generation of Thom Gunn, Geoffrey Hill, Ted Hughes, Sylvia Plath and Peter Porter. Here, author William Wootten explores what these five poets shared in common - their connections, critical reception, rivalries and differences - and locates what was new and valuable in their work.
