Sixty-five years ago Cyril Connolly reviewed Stephen Spender’s sexually candid and politically unsettling memoirs of his early manhood, World within World, with the intimate knowledge of a literary collaborator. ‘An inspired simpleton, a great big silly goose, a holy Russian idiot, large, generous, gullible, ignorant, affectionate, idealistic – living for friendship and beauty, writing miraculous poems’ was paired with a ‘shrewd and ambitious, aggressive and ruthless’ character, ‘a publicity-seeking intellectual full of administrative energy and rentier asperity, a young tiger sharpening its claws on the platform of peace,’ wrote Connolly in his matchless summary of the double Spender.
