In Alexis Wright’s novel Carpentaria (2006), Girlie claims, ‘If you ever want to find out about anything in your vicinity, you have to talk to the mad people.’ There are a lot of mad people in Wright’s biography of Aboriginal activist, thinker, and provocateur ‘Tracker’ Tilmouth. He is probably the maddest of all, in the Kerouacian sense of ‘mad to live, mad to talk’, but, according to his mate Doug Turner, his ‘madness gave him sanity’.
