The question of Woolf’s illness, a mental illness, and physical illness as well, is a difficult one. Her husband, Leonard Woolf, defined it as manic depression, and perhaps that is what it was. There is that sense of the highs and the lows, and certainly the great intensity of periods that she came to finish; all of the novels do seem to mark that sense of extraordinary intensity of perception, extraordinary intensity of the world. She also gives us characters like Rhoda in The Waves, or Mrs Dalloway in the novel of that name, for whom the world is a very dangerous place. She thought, she says in Mrs Dalloway, how very, very dangerous it was to live only one day. I do think those perceptions, the sense of the risks that are taken just in the very act of living, but also the very huge and extraordinary intensity of perception, of poetic imagination, does shape and colour her novels in profound ways.
