A life is one kind of biography and the letters are another kind of life, but the internal story, the true story is in the Collected Poems. The recent attempts by Motion and others to pass judgement on Larkin look awfully green and pale, compared with the self-examinations of the poetry. They think they judge him? No, he judges them. His indivisibility judges their hedging and trimming. His honesty judges their watchfulness.
