A self that goes on changing is a self that goes on living': so too with the biography of that self. And just as lives don't stay still, so life-writing can't be fixed and finalised. Our ideas are shifting about what can be said, our knowledge of human character is changing. The biographer has to pioneer, going 'ahead of the rest of us, like the miner's canary, testing the atmosphere, detecting falsity, unreality, and the presence of obsolete conventions'. So, 'There are some stories which have to be retold by each generation'. She is talking about the story of Shelley, but she could be talking about her own life-story. (Virginia Woolf, p. 11)
