It's a feature of our age that if you write a work of fiction, everyone assumes that the people and events in it are disguised biography — but if you write your biography, it's equally assumed you're lying your head off. This last may be true, at any rate of poets: Plato said that poets should be excluded from the ideal republic because they are such liars. I am a poet, and I affirm that this is true. About no subject are poets tempted to lie so much as about their own lives; I know one of them who has floated at least five versions of his autobiography, none of them true. I of course — being also a novelist — am a much more truthful person than that. But since poets lie, how can you believe me?
